We contacted Castlehall as we had a number of cracks around our bays and landing windows as well as a lintel in kitchen that needed looking at. Paul came around and noticed that our window sill was causing the problem. He recommended Barry the window man who fitted new windows. We noticed a difference straightaway. No other builders we got quotes off had noticed this problem and I think if we had gone with someone else we would have been back to square 1 in a few years. Paul and his team then came in and completed all the work throughout our house, lintel and wall straps fitted, insulated bay, pointing, plastering, guttering and even added a back gate. We are very happy with the work and will definitely use again and have already recommended them.
