What Our Customers Say
“Sean and Gary and the team worked extremely hard for us over a 11 week period on a 1920’s terraced house. We had the following work done that we were very pleased with – Ground floor extension with bi-fold doors – New tiled floor laid – New kitchen installed – Plastering of hall landing and stairs plus front room – Rear and front garden landscaped including fencing and walls etc. which they designed themselves. – Downstairs pantry converted into a toilet/cloakroom The build came in on budget and on time. Overall very pleased indeed. Once the build was finished Sean contacted us to ensure we were happy with everything and tidied up any snags. Would use them again.”
“They completely refurbished our house inside and out, we left them the keys and they designed the whole project themselves. We were very pleased with the result. We had used them previously for smaller jobs which we were satisfied with and trusted them completely with this job. Would use again.”
“Very good workers. Very good knowledge of the work they were doing for me and of other work I asked them about. Didn’t mind giving their time to explain things. You could not fault the quality.”
