Roofing (Pitched)- 14 Nov 2017
Marcin was a pleasure to deal with! He is knowledgeable and professional - he came and explained clearly what needed to done, he emailed me materials' list required and suggested suppliers with product links and he was very helpful at agreeing between us who will be supplying what material. He came and did the job without disruption, in an efficient manner. While he was quick he was thorough to ensure the job is done to a correct standard. He is smart and finds solutions that work. I wish every tradesperson was like him!

Bathroom Fitting- 13 Jul 2023
We honestly can’t recommend Orland highly enough. He came in mid job after we got abandoned by some shady builders, and was just fantastic. Built us a wonderful bathroom in under a week - was polite, professional, arrived early and all his work was to a very high standard. Would definitely ask him to help with future projects!

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Conversions - General- 23 Jul 2025
I recently had the pleasure of working with Teimo and his team on a full renovation of a probate house, and I couldn't be happier with the results. The entire house needed a complete overhaul, including two new bathrooms, a kitchen extension, new doors, skirting, walls, plumbing, electrics, as well as front garden paving, a brick wall, and back garden fencing. The quality of the work is outstanding. Teimo and his team take immense pride in everything they do, and it really shows in the final product. They are not only highly skilled but also incredibly polite and tidy, ensuring the worksite remained clean throughout. They worked hard, from 8:30 AM to 5:30 PM every day, and completed the project on time without any issues. What truly stands out about Teimo is his honesty and clear communication. He’s upfront about everything, and you can trust that the price you’re quoted is the price you’ll pay—there are no surprise cost increases along the way I highly recommend Teimo and his team

Samouil and his team at KnowHow Decorating completed a major project restoring our house. Work scope included sorting the tired and broken windows , guttering , fascia panels. Replacing rotten window ledges was done with superbly crafted new hard wood. No task was too difficult as the house was looking shabby. Full painting inside and outside was really well done. We feel like we have a "new" house and Samouil and team are a pleasure to deal with. They go beyond to satisfy you . I do not hesitate to recommend them strongly and will use again anytime .

Extensions- 14 May 2025
Jon was able to take a failed project from a previous contractor and manage historic building preservation, regulation in Westminster, a lack of parking, plumbing from the Victorian age, and a demanding client to deliver a beautiful result. I love my garden flat extension, it manages to respect the historic nature of a building from the 1840s while also adding amenities to be proud of in 2025. Thank you Jon (and team) and best of luck with future business.

Questions to ask local loft conversion companies in Turnham Green

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 Turnham Green?

A local loft conversion company in Turnham Green 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 Turnham Green 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 Turnham Green 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 Turnham Green

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 Turnham Green before agreeing to start the work.

Do I need planning permission for a loft conversion in Turnham Green?

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 Turnham Green 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 Turnham Green loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
