Paul did an amazing job at my 3 bed, he built a shower room and toilet area downstairs from scratch and plastered and repainted the whole house with his specialist team within 2 weeks. This has been amazing as other contractors quoted between 6 weeks. I will definitely be using Paul's services in future as he sticks to the price quoted and is trustworthy

Restoration & Refurbishment- 18 Feb 2021
Ray was an absolute professional. He fitted a new downstairs toilet which required a new soil pipe and associated groundwork as well as new stud walling to partition the space. He did most of the work himself, but brought in others for the pieces where he wanted an expert. He was flexible to small changes and was happy to take on additional work when unforeseen issues were discovered. The areas he had worked in were quickly cleaned before he left each day. Overall the work was completed to a good quality and at a reasonable price.

Conversions - General- 17 Apr 2026
A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again

Bathroom Fitting- 14 Nov 2019
We had our bathroom completely refurbished and Graham the owner was lovely. He came to give us the quote, visited whilst work was being undertaken to make sure everything was okay and came to make sure everything was finished to how we wanted it. The work carried out was of a high standard and whilst the bathroom work was being completed we also ended up getting our kitchen worktops done by Graham’s team. Chris was the one who carried out our work, he was very friendly and checked we were happy with the work he’d done before he left everyday. I would use Graham again for other work needed around the house.

Electrical- 26 Jul 2026
Genuinely one of the worst builders we have come across. David rewired the flat and Stefan plastered the hallway. David is NOT qualified as an electrician and cut corners wherever he could. David leveraged us for money mid job and in the end left the job without finishing and without providing a certificate. David ran cables behind door frames (awful idea), got the cheapest material, forgot where holes were for spotlights and switches among many issues which meant we had to constantly ask our builders to fill the holes and make good. Stefan did the hallway plastering without putting on mesh. The plaster cracked within 2 weeks and the paint keeps cracking and will be a constant problem. When asked to come back and fix the issue - he point blank refused. They were the cheapest quote but we really hope we had gone to someone else

Windows & Doors (uPVC & Metal)- 28 Jan 2026
Very unhappy with how things went with Angle Construction overall. Poor comms during the transaction was the first red flag - no communication for 2 days the moment money was sent, however afterwards received an apologetic call - parts ordered and arrived in due course. Andrei turned up, and got to work on removing the old gate, but then started shaving down the post without saying anything -we were told after that the posts were not level. Eventually he said the door would need to be cut, which we agreed to. The door and posts were both cut to fit, but massive gap left at the bottom, and only half of the door fittings and no handles were installed! In addition, where the door was cut and the wood shaved made, a lot of mess was left all over the garden furniture and patio floor. Shocked at the lack of care and professionalism. He was clearly agitated and in a rush to leave. We have a working back door, but it looks like a real botched job. Not happy, and I would not recommend.

What to ask a Uxbridge extension builder before hiring?

Before hiring an extension builder in Uxbridge or extension building company in Uxbridge, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Uxbridge?

An extension builder in Uxbridge should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Uxbridge extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Uxbridge?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Uxbridge extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Uxbridge extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
