Bricklaying- 23 Jan 2025
Michael, Matthew and James , Came and rebuilt my garden wall, which was leaning and not safe, On Saturday at 8.30. We were very impressed how hard they worked to get the job done,the result looks great and they left it tidy. I would definitely use them again and would recommend Construct. On day one they took the dangerous wall down and managed to clean most of the bricks off and the following day rebuilt it just adding a few additional bricks. They are very polite, also their quote was good for us. Well done Michael and Matthew

Handyman- 22 Oct 2023
Ended up being a disappointing service. This trader was responsive at the beginning and addressed my queries after sending his quote however even when he mentioned that the job could be done in half a day, he had to come back more than twice after starting the job due to a lack of material, time or issues arising on his part, etc. A month after the job was completed the hatch fell off the ceiling and the trader said “I’ll be there tomorrow at the latest”, never replied at what time, I had to reach out several times as he was irresponsive and in the end did not come back anyway to fix the poor job and rather wanted to charge for any “extra” work conducted despite the hatch was already paid for. He said “find someone else to do it” and has not provided a partial refund either. I would not recommend him as clearly did not take proper care to do the job I paid and has no inclination of after care once he has the money.

Stonemasonry- 1 Jun 2025
He turned up exactly when he said he would, and from the moment he arrived to look at the job, I could tell he knew exactly what he was talking about, he offered me a few solutions, of what he could do to fix the problem. He said he would give me a call the following week to confirm when he could do the job, and he did just that. On the day he turned up, on time, he set up his gear and proceeded . I had prepped the footings to strengthen the buttress, and he seemed pleased with that. He did exactly what he said he would do, cleared up well afterwards. As for the quality of the job he did, perfect, exactly what I wanted, and very happy. I can recommend this stonemason without question. Ps. He likes his capachino coffees, no sugar. Thanks Jed.👍
