Decking- 9 Jul 2026
I couldn't be happier with the decking Syed and the team installed. From start to finish they were incredibly professional, friendly, and worked at an impressive pace without compromising on quality. Their workmanship is absolutely top tier, and the finished decking looks fantastic. What really stood out was that they even completed a section of the decking that I hadn't asked them to do. It was a genuinely kind gesture and shows they take real pride in their work and care about their customers. Syed and the team were attentive throughout the whole job, always happy to answer questions and make sure everything was done exactly right. They're a great bunch of fellas, and it was a pleasure having them here. I wouldn't hesitate to recommend Syed and the team to anyone looking for quality decking, and there's no doubt I'll be using them again for future projects. Thank you all for an outstanding job!

Handyman- 15 Apr 2026
Joe is incredibly diligent, polite and does a great job. Initially hired him to fix some drawers and help with a couple of small things but was so impressed have been using his services for other tasks, which he has done really well - staying incredibly late until the job was done, which I wouldn't normaly expect. He can be very busy but that is normal for someone who is very good at their job! Would definitely recommend. Also he is extremely tidy and a nice guy.

Gas Work- 7 May 2024
Florin has done a great job to replace my gas system boiler. He worked hard to finish the job in one day, in fact stayed late evening to make sure the job was completed. He registered the boiler, provided the building reg and Lanlord certificate. I will recommend him based on my experience and will use him again in future.

Loft Conversion- 26 Dec 2019
Working with Dil was a pleasure! From the the outset he was very helpful with calculating overall costs (over and above his costs) for the build to ensure everything had been catered for and was very thorough in checking that my ideas/plans were appropriate for the long term. It was through the initial discussion that some minor adjustments were made and for the better I believe, simple things like where the new Megaflow System should be placed. He was very quick and efficient in identifying where there may be issues upfront and has the right contacts to get things sorted to minimise problems further into the build. I had to get a new mains water pipe installed which to me was a a major job but he got it sorted very quickly through his contacts at a very reasonable cost. His team are very polite and they do a as good a job as possible to minimise impact on your daily living if like us you are living in the property during the process. Essentially a team of 3/4 guys who are capable of doing most things however Dil does call in specialist trade as and when needed to ensure the job gets done in a timely manner, for my build he called in roofers and certified plumbers for the boiler. Only negative is that you have to watch the silicone sealant finishing which is not the tidiest but a minor in the grand scheme of things and if you don’t like something you simply have to say and he will redo within reason. Overall a very happy customer

Carpentry- 21 Dec 2025
Viktor and Michael are very friendly and professional. They were on time and the price quoted was the price I paid. I hired them to install architraves around 4 internal doors and I am very happy with their work. They made sure I was happy with the work before they left and they took time to clean up after as well. They take real pride in their work as all the joints are perfectly aligned and all the nails are sunk in to the wood so I can apply filler afterwards and paint. Viktor also made a quick trip to Screwfix to ensure he used the strongest adhesive to fix the architraves to tiles in the bathroom. I will hire Viktor and Michael in the future to refurbish my stairs and install wall panelling on the stairs wall. I highly recommend them for their honest and professional work.

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.
