Carpentry- 19 Apr 2012
It was an absolute pleasure having Danny round to fit our new Front Door. He arrived promptly, worked extremely hard and completely the job to a very high standard. He always works with a smile on his face and is an extremely amiable person. You will not be disappointed if you hire him for the job and I'll certainly be using him again in the future.

Bathroom Fitting- 7 Jun 2026
We recently had our bathrooms refurbished by Vasile and his team, and we are absolutely delighted with the results. From the very beginning, they were professional, reliable, kind, and exceptionally helpful. Vasile was always available to discuss every aspect of the project, taking the time to explain things clearly and answer our questions with patience and honesty. It felt as though we had a genuine partner supporting us through the renovation of our three-bedroom flat. Vasile and his team were fully invested in achieving the best possible outcome and were always willing to go the extra mile when challenges arose. The quality of their work is outstanding. They worked efficiently, kept us informed throughout, and ensured everything was completed in a timely manner without compromising on quality. We would wholeheartedly recommend Vasile and his team to anyone looking for skilled, trustworthy, and genuinely caring professionals.

Roofing (Flat)- 2 Aug 2023
Stay clear of this person as he is not experienced builder and do not fulfill his commitments after taking money. Don't hire this tradesman unless you want someone not to turn up on agreed date and time or you want to chase him again and again without him picking up your phone calls or answering them.. My garden shed was leaking from the side. Amarjeet recommended to put new flashing on the garden shed roof to fix it. However, after putting flashing, the garden shed continued to leak from the same area he had put the flashing. He said this time the cause of leak were the joints which he failed to look into earlier. So, he fixed that. After second fix, the shed again leaked, this time directly under the flashing he had put. When I asked him to fix it, he refused saying that the issue is with the joints and not the flashing. I told him that I had hired him to fix the water leak and not the flashing or joints. I even said that I will pay him if the issue is different. After ringing him several times and then agreeing a date and time with him, he didn't turn up. He is not a professional or experienced builder. Having now spoken to another builder, they suggested that the issue is that the water is somehow going under the flashing he had put. There is a bigger problem of the water standing on the roof which needs to be fixed first and which this builder failed to notice. Unfortunately, I will have to pay another builder to complete his work!

Extensions- 18 Oct 2017
I asked Prohaus to undertake a ground floor side return and rear extension as part of the refurbishment of my flat in Putney. I have used many builders before on development projects but was especially impressed with Naz and his team on this build. It was the first time I used them and won’t be the last. Naz was great to work with, the whole build went smoothly and he always had a positive attitude and solution to any unexpected issue. The build came in on time and budget which was very impressive in itself. All in all I would highly recommend him.

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

Questions to ask local loft conversion companies in Hounslow

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 Hounslow?

A local loft conversion company in Hounslow 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 Hounslow 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 Hounslow 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 Hounslow

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 Hounslow before agreeing to start the work.

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

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