Plumbing- 2 Jun 2026
Excellent. I needed someone to remove an existing washing machine and for a new one when it arrived. Shaun was on the job immediately, arrived when he said he would, and did the job efficiently....returning a week later to fit the new machine. Reasonable price charged. Honest, friendly and respectful. Hoping to get him back for other work in the future.

Restoration & Refurbishment- 20 Jun 2026
I can’t rate Luke and his team highly enough - they were exceptional. They fitted the new kitchen, did the complicated electrics, carried out joinery, plastered, tiled and painted (as well as rectified a nasty area of damp) all to an extremely high standard. Each one of the tradesmen were polite, professional and a pleasure to have in our house. Luke provided a very detailed quote and fulfilled all his obligations to the letter. We are pensioners with health problems so it is essential that we can trust tradespeople: Profurb are reliable, clean and tidy, and highly skilled. What could have been an anxious renovation project was smooth and hassle-free. I’d recommend Luke, Jimbo and the other members of the team without hesitation. (Oh, and the kitchen-diner looks wonderful!)

Extensions- 17 Oct 2020
Overall an excellent build. Although this was a straight forward build, foundations, concrete floor, single skin blockwork walls, pitched roof with corrugated bitumen sheeting roof, key to the build was the flatness and levelness of the concrete floor and neatness of the blockwork and pointing on the inside as it was not to be rendered on the inside. My initial concerns of using a Contractor I had no previous direct experience were gradually alleviated as the build progressed. James, Greg and their team were good workers and skilled at their trade, particularly Dan and Harvey. My real concerns over the ability to delivery the quality floor were dispelled when seeing the team at work, Greg takes the lead for groundworks and blockwork and did an excellent job. The quality of the blockwork has attracted many positive comments from passing neighbours, as has the finished roof, soffits, facias and bargeboards. The use of AGR for the demolition and groundworks and GMC for the high spec. concrete can be highly recommended. The use of 'Ozzy' (Paul Evans) for the small fibreglass flat roof can also be recommended. Early on in the build I had some concerns about material shortages on site meaning that precious hours of good weather were being lost but a sharing of these concerns resolved the issue. JH were open to consider changes and extras on the build for which I was grateful. Communications with the client is key and there were a few times when I had to chase for info. Very happy.

Plastering- 28 Dec 2021
Lloyd from LGM Builders called to give me a quote to plaster my bedroom walls and ceiling. He was very helpful and friendly. He suggested putting insulation boards on the outside wall to keep the heat in. I also needed one new board on the ceiling. I was told the whole job would be 1 day prep and 2 days work. Lloyd arrived alone and completed all the work in 1 day and asked to be paid. I never expected to have any problems and paid him by bank transfer that evening. I then discovered that the new boards covered my window sill and also didn't allow enough room for the new radiator to be fitted without moving the pipes. Lloyd purchased a new window sill on my behalf and said he would return to fit later in the week. As the plaster dried I noticed lots of indentations and it was quite rough in places. When Lloyd arrived I mentioned the faults in the plaster so that it could be fixed. Lloyd's personality completely changed, his tone was aggressive, which made me feel very vulnerable and uncomfortable in my own home. He said he had done a good job and if I was a painter I would know that the indentations would need filling prior to painting. He then said he wasn't going to waste his time putting the new sill on when he could be working for someone else.
