This was not our first building project but it was our largest, involving an extension and comprehensive internal and external renovation in an old house. Igor/Combit were recommended by a good friend and the results exceeded our expectations. For us, the stand-out points were:

Quality: The quality of Combit’s building and construction work is outstanding. This is not just our view but also the view of our architect, and any subsequent friends or contractors who have visited the house, and who have better “in the trade” knowledge than us. It is clear that quality really matters to Igor.

Problem solving: Our project came with a number of challenges, some expected some unexpected. At every turn, Igor and his team always had a range of practical solutions which they discussed with us. All problems and challenges were resolved to our satisfaction

Reliability: Igor was always good to his word on timing and his team were always on site early/late as needed to get the job done. They were all always contactable (and quick to return our calls/messages when not available by phone or in person), and any minor end-of-project “snagging” is sorted-out quickly and without quibble.

Pleasant: Igor and his team were always courteous, helpful, and considerate.

Overall, a realistic, supportive and pleasurable organisation to work with, and with quality assured. 5 stars from here.

Working with Igor and his team at Combit was a truly commendable experience. The professionalism and courtesy of his workers were evident from day one, and they consistently ensured the workspace remained clean and organised.
Throughout the project Igor had an eye for detail, was hands on and was always contactable whenever we needed to speak with him.
We gutted the inside of our home which would usually take up to a year but Igor’s team managed to achieve our renovation in around 6 months whilst maintaining a high quality product.
Additionally Igor will stand by his work with after care support for any issues that may arise upon completion which gave us peace of mind.

We would happily recommend Igor to friends and family.

We recently hired COMBIT Construction, led by Igor and his team, to carry out renovation work at our commercial office building in Muswell Hill, London. They carried out refurbishment to a high standard and also helped resolve some other issues and carried out general building maintenance.

Throughout the project, the team were professional, accommodating, and responsive, even as additional tasks arose.

Ivan, in particular, deserves special mention for his exceptional work ethic, attention to detail, and commitment to getting things done properly. The painting and decorating were also completed to a very high standard.

I’ve worked with Igor and his team before and continue to be impressed by their reliability and quality of work. I would have no hesitation in recommending COMBIT Construction and would certainly use them again.

Igor and his team at Combit completed our home extension project in 2023. Everyone in the team was extremely hardworking, professional, and reliable. They clearly take pride in their work, which is reflected in the high-quality finish. Unlike other contractors who may leave things unfinished or cut corners, Igor is fully committed and ensures the project is completed to the highest standard. Even when carrying out remedial work well after the project was completed, they demonstrated the same level of dedication and professionalism. Thanks for doing such a great job.

Igor & his team did a fantastic job renovating my mother’s property.
I cannot thank them enough, we were so impressed from start to finish. Igor & his team are very trustworthy, hard working, friendly and kept the place clean after they finished work. Igor provided solutions during the works which was very helpful.
The whole property was renovated, which included all new fixtures and fittings. The old bathroom & separate WC was reconfigured into one large shower room. The electric meter and gas meter was relocated outside, new central heating, boiler installation, plumbing, all the floors were insulated. Also new windows, all external walls rendered. I would highly recommend Combit Construction and certainly use them in the future.

I am happy to provide this review for Combit Construction, who completed a full refurbishment of my house in 2018, including a loft extension, back extension, and various structural works. Igor was highly professional and demonstrated exceptional attention to detail, putting his full energy into the project. The work was completed to an outstanding standard, and as I write this review in 2025, it has truly stood the test of time. Combit Construction proved to be reliable and delivered high-quality workmanship, and I would happily use them again.

Our 1950s detached five-bedroom house underwent a complete renovation, both inside and out. The project included a loft conversion, new balconies, and a spacious 100m² extension added to the rear of the house. Additionally, built-in wardrobes were installed in all our bedrooms and the library, and custom desks were beautifully designed around our bay windows for our children—it looks absolutely stunning!

Igor and his team did a fantastic job, as you can see from the photos. He is an incredibly knowledgeable project manager who meticulously broke down every detail of the work required and its associated costs. This level of transparency was important to me, as it demonstrated his expertise and gave me confidence in the accuracy of his quotes. Furthermore, he provided numerous impressive testimonials, along with pictures and videos of previous projects, which reassured me that he was the right choice.

This experience was completely different from the other three companies we received quotes from. Their estimates lacked detail, and they made assumptions about our needs without asking the necessary questions.

Amazingly, the entire project was completed within the planned eight-month timeframe and stayed within budget! I highly recommend Combit Construction for any major house renovation projects.

Renovating a house can be quite stressful, we were lucky to find Igor and his team. They made the process smoother with good communication and honesty. They were professional and took pride in their workmanship. Our three girls were very happy with their new bedroom, bathroom and library. We highly recommend Igor and his team.

I couldn’t be happier with the outstanding renovation work Combit Construction completed on my flat. From our very first meeting, Igor demonstrated exceptional professionalism and attention to detail. What particularly impressed me was their ability to navigate the complexities of working within an apartment block with numerous restrictions.
Igor’s communication throughout the project was exemplary – always clear, prompt, and proactive. His team was not only highly skilled but also a pleasure to work with, maintaining a positive and respectful presence throughout the renovation. The quality of their finishing work truly sets them apart, with every detail executed to perfection.
The project was so successful that several of my neighbors have since hired Combit for their own renovations, and they’ve all shared similarly positive experiences. This speaks volumes about the consistency and reliability of their work.
For anyone seeking a trustworthy, skilled, and professional renovation team, I wholeheartedly recommend Igor and the Combit team. They’ve proven that high-quality craftsmanship and excellent customer service can go hand in hand.

Combit Construction extended the back of our house and renovated it. We were very pleased with the quality of the work. Igor made some very good suggestions along the way. His staff take great pride and care in their work and are pleasant to have in the house. I have no hesitation in recommending Combit Construction for any building project.

Igor, Ivan and their team took over a project mid stream having had difficulties with a previous contractor. The team delivered excellent results , have a fine eye for detail & are very good at solving problems onsite. highly recommend.

The quality of work carried out by Igor and his team was to a high standard and they are especially good at solving any unexpected problems that they may encounter. They do not cut corners and Igor always speaks to the customer before carrying out something not on the original brief. Igor’s team is polite and always clear up at the end of each day.

Combit Construction represents a team of highly skilled professionals. They provided a clear timeline and budget, and they stuck to both, which is rare in the construction industry. The quality of workmanship was outstanding, with great attention to detail and high-quality materials.

What impressed me the most was their commitment to customer satisfaction. They addressed any concerns promptly and made sure everything was completed to the highest standard.

Overall, I highly recommend Combit Construction to anyone looking for reliable and skilled professionals. I will definitely be using their services again in the future.

Igor and his team removed our dilapidated lean-to conservatory and built a beautiful new extension in its place. In addition, they turned what was our old kitchen into a shower and utility room, building sleek cupboards to house our paraphernalia so that the new open plan kitchen and living area remain clear and uncluttered. From the outset, Igor and Ivan were determined to make the utility room an object lesson in space saving storage and purpose built carpentry. Rezo and David worked tirelessly on the build, always punctual and professional. The team also came up with the possibility of a wrap around patio, where there had been old paving slabs and broken concrete. All of which attests to Combit’s special quality – the team really care about their work and are only satisfied with the best possible results, offering creative ideas and clever solutions along the way. Igor was always on hand to support and advise, and made sure that we were kept abreast of costs so that there were, in his words, ‘no nasty surprises’. This was very reassuring. So thank you all at Combit for your workmanship, care, creativity and enthusiasm.

Combit Construction deconstructed a three bedroomed semi detached house and built us a dream house. It was not an easy project but the expertise and professionalism of Igor and his Team ensured that we have a very solid and well constructed home. If you would like any more details or a verbal recommendation please contact me via Igor.
We would highly recommend this company, they go the extra mile.

We found Combit construction staff extremely hardworking. The builders turned up promptly, their work was of a high standard and they always cleaned afterwards .The job was done to our complete satisfaction. Combit construction did an amazing job for us. Thoroughly recommended.
Dina and Abdulla

Igor, Ivan and the team are superb, high quality workmanship, superb finish and price was good. They kept my house neat even though we were in the house when the renovations took place. Highly recommended.

I’ve worked with Combit Construction on my kitchen extension project. It was a big project, but Igor and his guys did an excellent job, accommodating all my requests. I’m very pleased with the final results. Igor also provides 1-year guarantee on the work his guys are doing, which I’m very happy to see.

I chose Combit Construction after a Google search for renovation specialists in North London. I was renovating a two-bedroom flat and wanted to get a few quotes for the job. I received quotes from three different companies and I went with Combit.
I chose Combit because I found Igor to be very thorough in understanding what I wanted to achieve, my budget, and time scale. Igor’s quote was not the cheapest however, it was the most thorough, and well-thought-out.
Throughout the build, I found that Igor’s workmen were working to a very high standard and when challenges arose Igor knew how to resolve them.
I would have no doubt in recommending Igor to others and he would be the first person I would turn to for future projects.

I worked with Combit to extend and open-plan the ground floor of our home. Igor, Rezo, Ivan, Oleg and the rest of the team always worked tirelessly to ensure the highest possible quality and that we were always satisfied with the work being done. Igor is a trustworthy adviser, always on-hand to provide creative recommendations and collaborate together through any challenges that our project encountered. I would give the highest possible recommendation to Igor and his team, without reservation. I look forward to working again with them in future.

Igor and his team did a 2nd project in our house. This time it was constructing outbuilding in our garden – gym + shower room + sauna. Plus also renovating our garden in the process.
Guys did a great job, as always, we’re happy with the results. I’d recommend Combit Renovations company.

Igor and his Combit team completed a big and complicated flat renovation for us. We basically completely redid our whole flat, that is change all flooring throughout (level, sound insulate, and new flooring), change all ceilings throughout (level, sounds insulate, and new lights), new kitchen, two new bathrooms, renovate/improve our balcony, etc. Moreover, we’ve done all this while abroad keeping in touch with Igor on a nearly daily basis through a combination of calls, videos, and messages – which he was sending us about our project.

We’re extremely happy with the end result (see pictures). We obviously encountered quite a few unexpected problems along the way and Igor & his team were really good at resolving them. The end result is very high quality, even better than we had hoped! See for examples how nice the flooring looks or how nice the tiles were installed in the bathrooms. My neighbors also commended the team for being very tidy & quiet in the common areas.

Thank you to Igor and his team for taking on our large downstairs and first floor bathroom renovation project. Igor and his guys were thorough and professional, worked quickly and carried on with the works while my family and I were still living in the house. They completed the job by our requested deadline.

Igor and his team did our rear extension, which included significant demolition, structural alterations and bespoke interiors. The project has its set of challenges as we found some surprises in our existing structure after the demolition phase, but full marks to Igor and his team for being patient, methodical, solution focused, and always coming up with creative ideas to solve problems. We were staying upstairs with young kids through the duration of our project and Igor’s team were extremely sensitive to this, respected our space, and minimising disruptions where possible. The finish is fantastic, and all thanks to Igor. They also subsequently returned to rectify minor snagging one year after completion demonstrating his commitment to customer care.

My wife and I went with Combit Construction for our garage conversion and we are very happy with the end result. The construction was at a period when COVID restrictions were in force, but Igor made sure the project completed on time and on budget despite additional works that were unforeseen. He went above and beyond to make us happy, including liaising with the Local Planning Officer on certain matters on our behalf. We felt the pricing was competitive, and the builders were professional and reliable. Highly recommended.

We renovated our 2 bedroom apartment using Combit Construction. Igor and his team are very hard working and reliable. Any queries were answered immediately. Igor gave us advice and quickly came up with solutions and suggestions for challenges that we encountered. At the end we were quite pressured for time, but the team made it possible for us to move in without major delays.

“We needed to convert our garage into a room years ago but because of our bad experiences with builders in the past we could not face the mess, the music, the shouting, the not knowing whether the builders were going to show up, the starting late and leaving early afternoon, all the problems they kept telling us we had, the surprised extras on our final invoice, etc.
However, it came to a point that we really had to convert the garage and on asking around we were recommended to Igor at Combit Construction.
From the moment we spoke to Igor and subsequently met him, our faith in builders was restored. He is totally dedicated to his work and we felt like his only clients because he came round so many times during the day to check on the work. He always makes himself available to speak to you and always very obliging and helpful.
We cannot recommend this building firm highly enough.
We found everyone extremely efficient, hardworking, reliable and so polite.
They were unobtrusive – never heard a raised voice or radio. Always tidied both inside and outside every day and always were helpful with suggestions and ideas.
They took a pride in their work, were loyal to each other and always so helpful to us in so many ways. Never came to us with problems – they solved the problems, and the only extras on our final invoice was what we had added on ourselves – Igor always keeping us aware of the additional cost.
Furthermore I know they will also give a good aftercare service.”

I was let down by my previous builders and called Combit Construction to help me to finish my project – converting 4 bedroom house into HMO.

Igor provided me with a very detailed quotation and reasonable cost.

I felt that I could trust Igor and his team as the project took off quickly and progressed very well.

It was a pleasure to work with Igor, as he gave us lots of helpful advise and took care of entire project.

Our communication was really good. I received video and photo reports regularly.

I came to visit the project only once – at the completion. I was really happy about all building stages and was very delighted to see the completed project with all attentions to the details.

I would happily recommend Igor and his Combit Construction team to everyone and definitely looking forward to use him again in my next projects.

It was a delight to know workers who took pride in their work.
They were professional, thoughtful, respectful, on time and went the extra mile to complete the job in the allocated time.
Igor and his team worked on demolishing a back garden wall and replacing it with wood panels. Concrete the back garden. Pointing exterior walls. Painting exterior of whole house . Repair and render window sills. Power washing some areas making it look like new.
Carried out some small extra work, all at high standards.
I am very pleased with the completed project and would recommend Combit Construction.

We have just finished our house renovation with Combit Construction and we are extremely happy with the work Igor and his team have done.
From the first meeting we felt like Igor was reliable, experienced and professional.
All the works have been carried out timely, precisely and at high standard. The guys were always professional on the job and were always leaving everything very clean and tidy at the end of the day.

Igor and his team did a fantastic job with my extension and extensive groundworks/landscaping, working through a very wet winter and Covid (within guidelines). The quality of the work is exceptionally high – Igor and his team think about both the aesthetics (they all have incredible attention to detail and provide suggestions on the finishes) and the long-term functionality and practicality of the build – they do not cut corners. Igor and his team were very polite and friendly and you could see genuine delight in making their clients happy. I would highly recommend Combit.

Excellent professional workmanship was delivered by Combit Construction. Igor and his team delivered exactly what we required and to a high quality finish. This is the second time we have used Combit and would highly recommend them to others who are looking for exceptional work and honesty.

I just had extention work done to my house (loft, side and back extension). Amazing and friendly team and more importantly started and finished on time. Price is reasonable and quality is high. Helped me through planning permission, building regulations and contraction work!! Always available when needed. My wife is happy with everything especially new kitchen !!
Would definitely use them again!

We hired Combit Construction for a rear extension and interior refurbishment on two floors.
Igor was pleasant to deal with throughout and his work is of a high standard. He made helpful suggestions along the way and gave us tips which saved us money. His workers were pleasant to have in the house and took pride in their work. They left everything clean and tidy at the end of the day.
Igor has been back several times to fill in cracks etc. It is easy to contact him and if he can’t take a call, he will always return it later.
I have no hesitation in recommending him.

Igor and his team did a fantastic job extending our house plus a full refurbishment. The work was of high standard, pricing very fair and communication was excellent. We would happily recommend him.

I live in North London and I looked around for a while for someone who I felt would offer me the best service. Without doubt doubt Combit did that and I would highly recommend.

Thank you so much for your amazing job! Did a great job here at my home in north London 🙂

Friendly, knowledgeable team, I wouldn’t go anywhere else!

So impressed with Combit Construction, it’s so hard to find people so reliable and affordable in North London. I’ll definitely be working with them again!

We love our new kitchen! So much more light and room with the extension. The Combit Construction team are outstanding. Very pleased with the quality of their work.

Combit did our loft extension and both my wife and I are very pleased with the result. The work has been finished to a very high standard and was completed on time and in budget. Thank you guys!

We needed some structural modifications made on our new house, however, only just moving to London we did not have any contacts.
After researching numerous builders we found Combit Construction who were the first company who we felt comfortable working with.
Igor was always readily available and talked a great deal of sense, without confusing the customer with building jargon.
They were able to give us a date that fitted with our schedules well and completed the whole job in a day without fuss, and all at an excellent price!
I would highly recommend them to anyone and will certainly be look to use them again when we require further work.
Many Thanks.

Had a minor construction job to do. Combit did the job well and cleaned up after themselves. Were polite and the charge was very reasonable.

Combit Construction turned up on time and carried out the work to a very high standard. The finish was very good and I was consulted on any change that had to be done. My budget wasn’t high but they treated me very well and provided a friendly service. They went the extra mile to produce a lovely kitchen for me. I would, and will, happily use them again.

Not all builders are the same. Igor and his team are reliable, diligent and thorough. They produced a great finish. Igor is easy to contact and will do what he says he is going to do. They are also trustworthy people. Happy to recommend them

Igor and his men took care of our office extention very professionally from start to finish.
They coped very well with a few unexpected situations that appeared on the job, showing high quality decision-making skills and sound judgment.
They also showed great sensitivity in continuing work without disturbing anybody in a very busy working environment.
I can’t recommend Kombit Services enough for your Building Works, you can relax , your work is in good hands

We recently used Combit Services to totally renovate a house and were very pleased with the outcome. They were efficient, tidy, considerate to the neighbours and completed the job within the timescale and budget. We will definitely be using them again!

We would highly recommend Combit Constructions as their workmanship is of a high standard. Their maintenance contractors are always happy to take on any required work that is asked of them.

Through comments from our clients Combit Constructions provides a great standard of maintenance work throughout the eight floors of our building.

Having Combit Constructions on our site gives us ease of mind for the maintenance of our building.

Efficient, reasonably priced, honest and reliable, all rare commodities in this industry. I would use them again.

The front of our house was painted and re done with meticulous attention to detail.Our kitchen and living room were completely refurbished and heating system re done. we were given plenty of advice, the work is good quality and of a high standard. The living room was given another 3 coats of paint when we thought it was finished as Igor and his polite team are perfectionists. There is no cutting of corners and yet the price compares well. I would recommend Igor and his team to anybody and definitely use them again.

Igor Korenev and his excellent team at Combit transformed the front of our house. The quality of work and materials was first class and Igor, with his eagle eye for detail, kept checking on everything and was only satisfied with top-quality work from his experienced and professional employees all of whom were delightful, hard-working and caring.

Timekeeping was meticulous and Igor ensured that everything was done at times convenient to us. Igor supervised everything on a daily basis and I was particularly grateful for all of the advice he gave me about what was needed such as fixing and cleaning the drive and wall and the way in which the house was painted.
Igor has an instinct about what will look best. Combit Services completed a first-rate job using top-quality materials and labour and provided top-quality customer care. Thank you, Igor and Combit Services. I have had no hesitation in recommending you to my friends.

Combit Construction have recently completed a project at my home in Edgware where the old conservatory was replaced with a larger extension/conservatory. All of Igor’s team were clean, trustworthy workers and Igor, himself is a man of high standards and expects those standards to be reflected in the quality of the work his team produces.
