His service was very great and precise and seeing him working made me realise he is very experienced in his work. I will definitely call him for any other work that needs to be done.

We recently completed a full house refurbishment including a 4-metre rear extension, dormer loft conversion, and complete interior renovation with ALMO Property Group—and I genuinely couldn’t recommend them more highly. From the very beginning, the team managed everything seamlessly, from planning and design through to execution. What could have been an incredibly stressful process was made smooth, organised, and surprisingly enjoyable thanks to their professionalism, communication, and attention to detail. The quality of workmanship throughout the project has been exceptional. Every stage was handled with care, precision, and a clear commitment to delivering a high-end finish. The team were reliable, efficient, and always kept us informed, which gave us real peace of mind. A special mention has to go to Ameer, who was absolutely outstanding from start to finish. His dedication, responsiveness, and willingness to go above and beyond made a huge difference. He was always on hand to answer questions, offer solutions, and ensure everything ran perfectly. ALMO Property Group have completely transformed our house into a beautiful home, and we are beyond happy with the results. If you’re looking for a trustworthy, skilled, and professional team, I would highly recommend them.

Asen did an incredible job! In just under 4 weeks he managed to assemble a team and complete renovation on a 2 bed flat including: * Full rewiring, new lights, updating and adding sockets * Fixing rotten and uneven subfloor and levelling the whole house * Wood flooring throughout - done excellently with no thresholds * New boiler and all new radiators * Built a pocket door at the porch to stop our kitties from escaping * Tiled the fireplace * Skirting, decorating and repainting the entire flat * Dealt with gutting the place and arranging pickup of rubish The place looks and feels amazing and everything works! Asen was good on the price, kept to the (very tight) timelines, great communication throughout and overall very professional and friendly! Pics shows after and during the work, ignore the moving boxes.

Conversions - General- 11 Oct 2022
We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!

Painting & Decorating- 7 Dec 2021
I chose Fayn as it provides detailed breakdown on a written quote, similar way of quote for large construction project. I hire it to do two two jobs - #1 repair previous flush light damage; #2 repair painting hook holes. I am happy with the job #1 but job #2 could have done better. For job #1, he has kept the place clean and tidy, ceiling area near flush light becomes smooth and nice. He is polite. For job #2, I was hoping to hide the tiny painting hook holes but they end up enlarged marks on wall. I must say the paint color I got isn’t quite matching, also a matter of new and old paint. I would appreciate him letting know me the color isn’t right after applying to the first hook instead applying to all, as well as using a smaller brush for tiny holes. He helps finding solutions by mixing paint. But every touch up just extends the area, so I had to tell him to start small for testing. He tried hard to make the mark less obvious.

Tiling- 23 May 2026
Peter deserves a 100/10 review — honestly one of the best tradespeople I’ve ever worked with. Peter completed all 4 of our bathrooms, including the tiling, a beautiful kitchen splashback, and laminate flooring, and the quality of his work was absolutely exceptional. His attention to detail is second to none — everything was finished to perfection, and you can tell he genuinely takes pride in his craft. What really sets Peter apart, though, is how professional and caring he is. From day one, he treated our home with respect and treated us like family — not just another job on his list. He was always punctual, communicative, incredibly hardworking, and went above and beyond at every stage. More than just doing the work, Peter offered amazing support and guidance throughout the build, giving us practical tips and advice that genuinely helped us make better decisions and avoid mistakes. That kind of honesty and care is rare. To put it simply: Peter is an angel. Reliable, skilled, trust

Questions to ask local loft conversion companies in West Acton

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 West Acton?

A local loft conversion company in West Acton 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 West Acton 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 West Acton 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 West Acton

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 West Acton before agreeing to start the work.

Do I need planning permission for a loft conversion in West Acton?

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