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.

I don’t usually write recommendations but if you are looking for a reliable , trustworthy and helpful bunch of all round builders these are your guys. We had a wall knocked out , flooring levelled and a chimney breast removed, we were fortunate not to have to live on site but they still tidied up every night and left it safe enough for our kids to pop home for a spontaneous sneaky peak. Nothing was too much and even as costs rose they helped to look for cheaper alternatives so we could still meet our design spec . They were on site every morning by 0830 and were only held up by delivery dates and the drying time of the floors and walls which were out of their control . They were even able to put us in touch with everyone we needed to do get the wow finish we wanted. We were that impressed we are back in the queue for more work !

Paul and his team did a great job converting my garage into a games room. I couldn’t be happier with the way it turned out, the quality of the work, and the general manner of the guys doing the work. Communication throughout was easy, and they left the job clean and tidy at the end of each day.

Fantastic service provided by Paul and the team we could not be happier with the end result. We had the whole house renovated, every room was ripped apart from new ceilings down to new skirts, and doors, internal wall removed for an open plan kitchen/diner, extension with a downstairs utility and bathroom, chimney's knocked out. Paul and his experienced team were very reliable and friendly. The project was finished in the specified times given initially to a very high standard. We didn't go a penny overbudget!! thank you to Paul and the team - Highly recommended. Corine & Matt.

Excellent service. We had a garage conversion providing us with a larger kitchen and an additional entrance / exit. Castlehall Builders were punctual polite and very professional. The building works started on time and the original estimated duration of the project was maintained. The standard of works was as we expected and we certainly had no complaints on the finished article. The price at completion was the same as the excellent value for money quotation. We will have no hesitation on using them on our next project. P & J B36
