Extensions- 13 Nov 2020
Matt and his team recently completed a fantastic job on our kitchen/extension and bathroom refurb. All of his team were great to work with and have on site, which really helped in what was at times quite a stressful space to remain living in. They always left the space as clean and tidy as possible which was appreciated. Matt specifically, was really flexible with us as we had delays in getting permissions and also were a little unclear on exactly what finish etc we wanted on things. He gave us genuine advice on everything from underfloor heating to the skylights and doors. We are so pleased with the finish of everything from the tiling and paving to the bathroom. Can't recommend Firtree enough, if we look to do the loft we will be straight back in touch. Many thanks to all, but special thanks to Matt, Sean, Dan and Joe who held it all together.

Loft Conversion- 15 May 2025
We had the pleasure of having Arben and his brother work on our loft, and I can't recommend them highly enough. The job was incredibly challenging, but they tackled it with skill, determination, and a great attitude. From start to finish, they were professional, efficient, and incredibly friendly. The quality of their work was outstanding - they paid great attention to detail and clearly take pride in what they do. It was a real pleasure having such trustworthy and skilled tradesmen in our home. Thank you, Arben, for the fantastic job!

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Latest review:
Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

We have known and worked with Joe for the last 6 years. He has recently built a ground floor kitchen extension and created a utility area and downstairs cloakroom for us. His ability to communicate each phase of the build’s requirements is brilliant. His craftsmanship is impressive. He has the ability to turn ideas into reality. Joe is a highly skilled plumber and electrician too which is hugely advantageous. He is professional and easy to have in your home. I can’t recommend Joe highly enough.

Mateusz, better known as Matthew, has just completed a job at my house consisting of replacing our bedroom ceiling, installation of downlights, repairs and redecoration, as well as the installation of a concealed shower, shower tray and cubicle, which involved some retiling and electrical repairs to mirror lights & switch. Matthew has done a great job, working conscientiously and paying attention to every detail. We are delighted with the outcome and it has been a real pleasure to have him working here. The work has been completed to a high standard and for a very reasonable price. I have already recommended Matthew to a neighbour and I would not hesitate to ask him back to do more work for us in the future.

I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

Questions to ask local loft conversion companies in North Finchley

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in North Finchley?

A local loft conversion company in North Finchley will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in North Finchley should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some North Finchley loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in North Finchley

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in North Finchley before agreeing to start the work.

Do I need planning permission for a loft conversion in North Finchley?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional North Finchley loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some North Finchley loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
