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.

Extensions- 30 Dec 2021
After getting a quote and feeling that James (Kelvin) knew exactly what he was doing, I was pleased I was going to get a bad job done well. After starting 2 months after the date quoted and paying a large amount of money for materials, which weren't delivered as quoted, Kelvin eventually started work (end of October), knocking down existing roofing, and leaving it without any cover for me to move between my house and bathroom, we then had the heavy rain, which he did say was on its way, causing water to get into my house and the bathroom. When he did start, being at work I couldn't see exactly what was going on. These are the problems we are now having after asking Kelvin to leave the job. After moving back door out a little, and external drain now being exposed on the inside of the house, it covered as an eco drain. After placing the cover (which we now know doesn't fit) over the drain, it was concreted up, which is against building regs, leaving any debris in the drain, so after having rain again this has flooded causing water to spread under existing flooring. Bad electrical work - with no name of electrician or cert as requested Life wires being left exposed Bad plastering - which Kelvin admitted he was no good at Roof leaking - no name of roofing company to get back to Floor tiles which he laid v v very badly - loose and able to take up without use of any tooling and not breaking any. I would not advise anybody to take him on as a builder

I chose Phil of Build-it because of the prompt reply and his quick assessment of the of the work required. He came in with a competitive price and he gave us a positive feeling that he would be able to complete the job on time and to the required standard. Phil and his small team started the job when promised and completed the work within the time they said. All the work done was to a very high standard and they left the job each day clearing up after them selves. I would certainly use them again if the need arises and would recommend them.

We have worked with many tradesmen over the years, and by far Dewie is the most considerate, conscientious, and tidy builder we have experienced. He came into our home, and with three very small children, we were understandably worried about dust, mess, and disruption. Dewie immediately put our minds at ease and was incredibly thoughtful throughout the process. He was forward-thinking with his quotes and approach to the work, ensuring everything ran smoothly. We can highly recommend him and would not hesitate to use him again for any future projects.
