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!

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Pawel and the team did a fantastic job. The bathroom looks superb and the whole team took time to finish the job to a very high standard. There was a narrow timeframe in which to do the work and this was met (despite more effort than first thought with respect to strengthening the floor). Pawel was easy to deal with and contacted me after the job to ensure everything ok. Highly recommended.

Haxhi and his team exceed my expectations. We did agree on a bathroom renovation which basically everything was done from scratch. He was always on time and he met the deadline of the project. I had an issue with my water pump but he managed to fix it for little cost. Also he did the tiles for me on the wall and floor with very minimum waste and he did a brilliant job. We changed the position of the basin in order to save space and we did replace it the washing machine(hidden). We are now working on my other property to renovate the bathroom. Hahxi is very professional, knows the job very well, he did coordinate with me on every step to make sure we are on the same page . I strongly recommend him for any renovation project you may have.

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 .

Paul and the team from Modern Attics converted our loft in Spring 2011. The job was completed on time and on budget. Every effort was made to limit the intrusion onto our lives during the conversion, particularly as we had a young son living at home. The building team were very tidy during the process and Paul's management through regular site visits, telephone calls and emails ensured a relatively stress free project. Any issues that arised were dealt with quickly and to our satisfaction. I would be very happy to recommend Paul and his team to anyone considering a loft conversion or extension.

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.

Questions to ask local loft conversion companies in West Hampstead

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 Hampstead?

A local loft conversion company in West Hampstead 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 Hampstead 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 Hampstead 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 Hampstead

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 Hampstead before agreeing to start the work.

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

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