Extensions- 31 Aug 2020
Luke and your builder ltd done our back and side utility room. Even though we’ve had lockdown and COVID 19 they done a great job. I’ve used your builder ltd a few times and the quality of work is of the highest order. What they quoted before they started is what I paid. Couldn’t be happier with the end product. Completely transformed our house. Would highly recommend them.

Bathroom Fitting- 3 Sep 2018
Mike was very professional from the start of our process finding someone to build our en suite bathroom. He came up with the best solution for the long soil pipe we needed and demonstrated the previous experience to make it work. He even tried to fix our existing toilet when he had just come to quote! Mike and his colleague Kear worked hard through a very hot week in July and always left the house tidy each day. As long as you keep providing tea with 2 sugars they just keep going! They even fixed our garage door, probably out of frustration of opening it each morning. I would recommend Mike for any bathroom or plumbing work.

Plumbing- 21 Nov 2022
Dawid and Mattusz were able to pop round to see the job shortly after I posted it. They gave me a good price and I gave them the go ahead to do the job as it was urgent. They were really nice, shoes off at the door (unprompted) and solved the problem. They cleaned up afterwards and were really professional throughout. I will be saving their number and using again!

An amazing result, very reasonably priced and professional service. We are really thrilled with the extension, Dave was able to answer any questions and adapt our specifications at a moments notice. He had been patient and friendly throughout and I have to say the work itself is exceptional. We sent pictures to family who are in the trade in London and the boss asked if Dave wants to do some work in London! If you are looking for a builder, I can't see why you'd go anywhere else. Thanks again Dave and Harvey

Connor and his team turned up when they said (weather permitting) and kept in good contact throughout. The quote was extremely reasonable and there were no changes. The work done has been to an extremely high standard. I cannot recommend this company highly enough and will definitely use them again. They were friendly, cheerful and hard working.

What experience do you have with similar extensions in Petersfield?
