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.

Carpentry- 16 Apr 2017
For a number of reasons, Reinaldo is without doubt the best tradesman I have come across, After having Cowboy Builders ruin my brand new doors. The quality of his work was faultless, he was prompt, always on time and very efficient, his work and work area was always left clean and tidy, and his communication skills, with regards to problem solving and making sure that the work he was carrying out was to my requirements, was excellent. I gave Reinaldo a number of jobs to do over a few separate visits and was not let down once. I cannot recommend Reinaldo highly enough and will be using him again for any future carpentry & joinery works. Reinaldo is not a carpenter however a magician as he can spell his Magic on any given work with a smile.Thanks again ,Reinaldo great work!

Loft Conversion- 10 Feb 2026
We had a great experience working with BS Loft Conversions on our L-shaped dormer loft conversion. Anxhelo was friendly, approachable and professional from the initial quote through to completion. We made a few changes as the build progressed, and he was always open to discussing options and finding sensible solutions. We found the original quote fair, and the additional items we added were also priced fairly. Anxhelo was generous with his time in offering advice on different aspects of the build, which we really appreciated. The team – Anxhelo, Klaidi, Henry and Jimmy – were on site consistently, worked hard, and are clearly experienced at what they do. At the end of each day, and at the end of each stage of the project, the site was always left very clean and well organised. Before choosing BS Lofts, we spoke to previous clients and heard positive feedback, which gave us confidence. Having now worked with them ourselves, we’re happy to recommend them to friends and family.

Extensions- 8 Dec 2021
Me and my wife are very satisfied with Prabbuilders work. What stands out with Prab builders is that they do every task as if they are doing it for their own house and with work they are meticulous and exceptional. What we started with and how our extension looks now is simply amazing and the way they explain about what will look good(Color/ the structure etc ) is commendable as we both were not sure what decision to make, but after completion we are overjoyed to see how excellent it turned out to be now. I would recommend them anytime based on their skill ,eye for detail, being punctual and the hard-work they invest into every task to make sure we are getting the final product the way we dreamt of.

Questions to ask local loft conversion companies in East Sheen

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 East Sheen?

A local loft conversion company in East Sheen 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 East Sheen 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 East Sheen 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 East Sheen

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 East Sheen before agreeing to start the work.

Do I need planning permission for a loft conversion in East Sheen?

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