Groundwork & Foundations- 1 Oct 2024
It was a complex job requiring the removal of an earth bank, ground works to include reinforcements to an independent engineer's specification, and re-erection of a boundary wall in a locally listed area against a busy road. We had some problems during the works but all were resolved to mutual satisfaction and with good humor. The end result is a high quality, solid wall of which Dave and his team should be proud

Roofing (Flat)- 9 Nov 2020
Darren & Son (plus Team) responded promptly to our advert for a Roofer in My Builder, they accessed the repair and quoted quickly. The work required was worst than expected but they tackled it with professionalism and speed and kept us informed of the work being done (via photos). They also cleaned up and disposed of all redundant waste. Thank you once again guys for being able to sort out what could have been a potential bigger problem and I would recommend then to anyone.

Bricklaying- 22 Aug 2022
Adam did an excellent building job, both brick work and carpentry, at the end he cleaned up and removed all the debris. What happened Adam started on Tuesday 16th August and expected to complete the work in 1 day, but he had to return the following day. Wednesday he worked till mid-day, leaving to work on another job. Thursday he didn't turn up, same on Friday. Eventually I managed to make contact with him and he said I will be there on Saturday. So on the Saturday we expected him at 8 to 8.30am. I rang him at around 9.00am to say where are you, he explained he had been working on another urgent job, but he would be with us around 9.30am. He arrived and by 11.30am the job was finished. We have a small well in our back garden, the roof had collapsed, it needed a large piece of plywood with tiles on the top. Adam said I will bring you a piece of plywood at no charge, either tonight or during Sunday, we felt very happy about the whole proceeding. Of course over the weekend no Adam arrived no plywood nothing, no email, or answer to my phone call. So finally on Tuesday we went out and purchased a large piece of plywood. So there you have it a very good workman, but keeping his promises needs to be considerably improved.

Restoration & Refurbishment- 2 Apr 2026
Really pleased I chose Leigh Matthews for this job. We were taking over a building that was unoccupied for 18 months and there were some issues with that, The team were excellent, and they finished the 4-week job on time, and right on budget. They were helpful and considerate and left the premises clean and tidy. They were also able to help out with some problems with the plumbing that were not in the original scope. I loved the way they did the estimate and the invoicing. Breaking all the items down into the individual tasks and at the end of each week, itemising which tasks were complete and a %age on those in progress. I would not hesitate to employ them again

Peter and team did a brilliant job refurbishing our kitchen. He organised building control sign off for knocking down an internal wall. He sourced new glazing for us and designed and built a custom bench seat. He assisted us with ordering the right units for our kitchen. He was great at problem solving along the way e.g. cutting cornice to fit tricky corners. The team were courteous and left our house tidy at the end of each day.

Extensions- 9 Apr 2017
Overall a good job. They got a very good match with the new bricks on the porch to our existing house and the porch looks good. The job did take slightly longer to complete than we had been told and there are a few small things that could have had a better finish, but then we haven't asked Bauer to put these right so can't fault them for what they don't know. Overall we would hire again and we are pleased with the result and value for money.

Ashley & his team did a outstanding job doing our porch. After we got let down by another contractor in the summer & was about to give up on doing the works this year. Found Ashley on my builder, it was the best thing that happened, he managed to turn it around & get it all done before Christmas for us. Excellent work from start to finishing. Prompt & reliable. Would definitely recommend Halsey construction.

Painting & Decorating- 10 Jul 2024
I recently had the pleasure of hiring Daniel to paint the ground floor of my house, including the kitchen, hallway, and living room. Not only did he do an exceptional job with the painting, but he also took the time to fix issues left over from a previous plasterer, all within the price we agreed on. Daniel truly went above and beyond my expectations. His attention to detail and dedication to delivering high-quality work was evident in the finished product. The walls look fantastic, and I couldn't be happier with the result. If you're looking for a reliable and skilled painter, I highly recommend Daniel.

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

An extension builder in Horley 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.

What experience do you have with similar extensions in Horley?
