Latest review:
I engaged Edi to work on a full renovation and refurbishment of a 4 bedroom detached house with front and back gardens on Blackheath’s Cator Estate. Edi did an extensive amount of work, including stripping out; plumbing; plastering; windows installation; carpentry; and decoration. In addition, after commencing the property work, once the scaffold had been erected, following sensible advice, Edi and his team replaced the roof and fully insulated the attic; fitted additional electric points; rebuilt the garden patio; and replaced the flooring throughout, in addition to other important jobs including re rendering and pointing of chimneys, building new wardrobes in the main bedrooms; and upgrading the radiators. A new kitchen, and two new bathrooms have been fitted. The kitchen redesign meant knocking through a wall with the lounge to create a larger space. Edi is a highly skilled craftsman, who thinks creatively as he works to make best use of the space, including shelf fittings, and additional lighting for example. He has built some beautiful wardrobes, and the internal decorations have brightened up what was previously a rather shabby looking house. In addition to the above, I wish to commend Edi for his professionalism, courtesy, and passion for doing the best work possible. On all the site visits I attended, and every time I spoke with him on the phone, it was striking how much he cared about the work that he was doing, his desire to ensure that the house would look the best. I always left site visits with the feeling that he cared so much about the house that he could be safely relied on to give the best advice to enable us to make the right decisions. I also noticed that Edi and his team would take the upmost care to keep the property safe, tidy and in good shape throughout the project. He can be fully trusted to look after any site he works on. He is intelligent and careful when it comes to safety and security. It has been a pleasure for Edi and his team to work with us over a period of around 6 months, and he did so much to reduce the stress of a significant project so that we could always rely on him to work methodically, patiently and sensibly, and to make best use of the resources available. His pleasantness shines through, and everyone I know who has spoken to him has always provided me with the most positive feedback I have no hesitation in recommending Edi to anyone who wishes to engage him for future projects, and is most deserving of the good words that I and others that work with him have to say about him.

Joinery & Cabinet Making- 19 Apr 2019
Marian is i would say a master craftsman . He did an excellent job with the 2 alcove bookshelves. The alcoves were big and i wanted most of the period features and he made it exactly as per my specifications he also helped mount my tv on one of the units and looks very clean and he also helped conceal all wiring for my electric fireplace. I will definitely use his services again.

Bathroom Fitting- 9 Feb 2019
Extremely pleased with the job Remi did. At the quoting stage he was upfront about costs we might not have considered, but still ended up being very competitive on price. During the job, he communicated clearly when he came up against issues; his fitting was to a high standard; he was on time and worked as long as he needed to each day to finish the job. His after-care was also good, as he returned to fix a related issue that arose during the work without quibbling; he also came back to complete fitting an item whose delivery had been delayed. Overall, I'd definitely hire him again.

Fencing- 13 Mar 2026
We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

Painting & Decorating- 12 Feb 2019
He truly showed professionalism that I had struggled as a guest house operator to get from handy people. He would go out of his way to satisfy. The finished redecorated room project was a masterpiece and took a little longer than planned because of the weather but he gave it his all! I am pleased I took a chance on him as there was no review on his profile when I hired him. I would however, pay attention to work and point out issues as they come up otherwise, you will have dirt and rubbish to content with as the workers leave all the mess after work.

What to ask a Finchley extension builder before hiring?

Before hiring an extension builder in Finchley or extension building company in Finchley, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Finchley?

An extension builder in Finchley should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Finchley extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Finchley?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Finchley extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Finchley extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
