I hired this company for multiple projects around my house, including a downstairs toilet, upstairs bathroom, hallways, media walls, and spotlights. I’m extremely happy with the quality of work and the overall service. I kept bringing them back for more jobs, which says it all. They were reliable, professional, and easy to communicate with throughout. Everything was completed to a very high standard and on time. Highly recommended — I would definitely use them again!

Carpentry- 17 Jun 2026
I cannot recommend Atilla highly enough. I originally brought him in to help with the carpentry work on my house build following a full demolition. The plan was for him to assist for just a few weeks, but from day one it became clear that he was exceptional at what he does. He was reliable, hardworking, highly skilled, and always polite and professional. As the project progressed, I ended up keeping him on for the entire duration of the build—around seven months. During that time he worked alongside various contractors, carpenters, roofers, and other trades, consistently proving himself to be one of the most dependable people on site. He became involved in virtually all aspects of the carpentry work throughout the project and always completed tasks to a very high standard. His attention to detail, positive attitude, and willingness to help wherever needed made a huge difference to the success of the build. Thank you Atilla.

Loft Conversion- 6 Oct 2018
Stuart at top floor conversions did a fantastic job at fitting a new loft hatch complete with ladder, light, moving our landing ceiling light, and boarding the attic floor. They were very professional, nothing was too much trouble - even with our very wonky house(!). They did a fantastic job clearing and cleaning after, and installing the new hatch and ladder. They did all the work within the day - big thanks to both of you! I could not recommend them enough!

Bathroom Fitting- 26 Jan 2019
Jav and Joe are nice chaps, gave a very reasonable quote and started really quickly (the following day!). We ended up using someone else for the floor tiles after Christmas (we already know them) so these guys took out our old shower enclosure and fittings and fitted new ones including tiling inside the cubicle. There was a damp issue and a leak beforehand- both of which they repaired to a high standard or came up with solutions to so that the job could compete in time for Christmas. They explained all our options well. They went out to get extra materials without an extra charge and worked at a weekend to get it finished in time. Pleased with the finish and I hear metro tiles are particularly difficult to get spot on. I would have liked a more comprehensive quote beforehand but they provide me with this on request and the job finished on budget except for the work around the unexpected damp which was a small extra charge and we were told about this before we went ahead with the extra work. Good all rounders who can do a whole job like this, altho for anything particularly specialist (such as complex patterned or mosaic floor tiles) I chose to use someone who just does tiling and that id already used- although they do work with a specialist themselves for such jobs and his work examples looked high quality so no need to source anyone extra if you want them to manage the whole thing for you. Would use again.

Loft Conversion- 1 Mar 2026
We can’t recommend Gary highly enough! A couple of years ago, he transformed our old granny-style bungalow into our dream home. He managed the project, removing the roof, adding a second floor, and gutting the ground floor/adjusting the layout with impeccable craftsmanship. Every detail was carefully considered, from electrics to tiling to high-quality cladding. Gary kept everything on budget, and had clever ways of helping us to save money, for which we could spend elsewhere. He also had great advice for adjusting certain elements of the build which we decided to implement. Communication was great, and we loved Gary’s brother Jon who worked day and night on the project and was lovely to be around with a great sense of humour. Gary and his team were not just skilled, but genuinely lovely to work with. We’re blown away by the final result, and we’ll definitely be calling him for future projects. Thank you Gary, Jon and team!

Questions to ask local loft conversion companies in Addlestone

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 Addlestone?

A local loft conversion company in Addlestone 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 Addlestone 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 Addlestone 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 Addlestone

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 Addlestone before agreeing to start the work.

Do I need planning permission for a loft conversion in Addlestone?

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