We were very pleased with the work done. Any mess was cleared away each day. They were friendly and answered all our questions. We were so pleased, we are now having a new front door and new patio doors fitted.

Jason came on time, carried out work efficiently, didn't break anything and cleared up completely so that when he left we would not know he had been, except for the two lovely new windows in the bathrooms.

Customer Service
Have just got home to see our new doors & windows, they look brilliant! Jason the fitter, has done a fantastic job, what a craftsman, his work is superb with great attention to detail and finish! as you can guess we're very pleased. John in the showroom & Alan in the factory were very knowledgeable and we appreciated their very helpful and professional advice. We wouldn't hesitate to use Harp Windows again and would recommend them very highly.
