We asked Ray and his team to lay mosaic tiles in the front, replace wooden post, tidy up the hole around the front window and lay bricks along the front under the fence which we brought already. The brick work was shabby and some broken bricks where used as well as the cut ones that were used to support other bricks when being cut even though we had plenty of new bricks. Wooden post was fitted, new front door with frame was fitted, this again was fitted poorly, key lock off centre, door handles were put in the wrong place, i shared my concerns re attention to detail, there were a number of issues which did get sort of resolved, the quote was based on 6 days, covering laying tiles, materials, fitting door, ring doorbell, filling in hole, I was asked to get the grout and the builders used our filler then gave me a receipt for more which Ray did take as this was not appropriate. The tiles were incorrectly laid, damaged and just wrong, due to this we were told we needed to buy more so we did. I held back the money for the labour as we asked several times for them to be corrected resulting in more damage. the ring doorbell bell wast fitted as it wasn’t battery and was dismissed. We now need our door to be filled and rehung which Ray offered to do but we don’t trust him or his team so he did transfer the money to cover the cost. We are still needing to buy new tiles and to get our front gate re powered coated due to damage and remove the cement from where the builders did the brick

Excellent Service & Finish We had a very positive experience with The Building Co team, who we used to carry out a dormer conversion in our property. We're delighted with the overall finish as the work was executed to a very high standard. Ray and his team were very friendly and the met the tight deadlines set to complete the work. We could not fault any part of the process. Really delighted with everything. Overall, we're very pleased with our decision to use The Building Co and have already recommended them to our neighbours!

Moving into a house in need of modernization, I had The Building Co replace a broken boiler, fit a new bathroom, demolish an outside toilet, and some other minor works. The work was completed to a high standard with no major issues, though works did overrun slightly. I was especially impressed with the prompt removal of waste, communication from Ray, and willingness to help out with smaller issues around the house.

The Building Company built a utility room for us on the back of our old cottage, they understood what we wanted the utility room to look like and matched the new build in with the old brick work of our cottage.They worked really hard and was always on time considering the bad weather, which didn't stop them. We are very happy with our utility room it's well made and even more spacious than we thought it would be. Ray was always very polite and approachable and even helped out with painting, when needed and was always coming around to Check on the work I can highly recommend Ray and his work team, we are very happy with our utility room.
