Great company! Fitted us in very quickly as we were on a tight turn around on this project. Reasonable price, tidy, professional, reliable… what more can I say or expect. Really friendly team and easy to deal with.
Turned up on time and did a fabulous job. Left the house just as they found it and the wife was so happy, it looks like the front door is next. Would have no issues in recommending to anyone. Thank you.
