Highlights
"Prime Build knocked the wall through between our kitchen and dining room. Removed an existing conservatory and built an extension in its place. They installed our kitchen, and fitted herringbone flooring. They also replaced the lintel in our upstairs window which had been leaking. The quality of work is excellent, Dan and Gary have been amazing through the process and were tidy and made the whole thing painless. I would highly recommend them for any building work and we will certainly use them again for future work"
"Great experience from start to finish! Communication and timekeeping were spot on. We always knew what was happening and when people would be arriving each day. The guys were always pleasant and courteous. We were living in the house while the work was taking place and everything was left tidy and safe each day before they left - important as we have young children. The work was completed to an excellent standard and we are really happy with the finished build. It has made a huge difference to our home and we are so grateful to these guys for doing such a wonderful job!"
"Lead flashing and roof tile replaced to a good standard. Flashing on lean-to roof replaced and attempted repair to flashing at roof and main building wall not completed satisfactorily even though builder said they would return to finish work. Repeated phone calls resulted in two visites and promises to sort on going issue. This did not happen and on the final call I was told to find someone else to sort the problem as they were to busy."

Check the TrustMark registerNever pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.

Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
