Excellent job done.

From salesman to completion of my front door, was excellent. Pleasant workers, tidy and polite. Staff in store were also excellent. Overall, a very good organisation.

Very happy customer

From start to finish, I received a good service. The quality of the windows and door seem good (much better than what I had). They were the most reasonable quote I had. Would recommend them to anyone.

Professional and friendly
Customer Service
Used Harp for new windows, and again shortly afterwards for a new door. Very professional - no hard sell, just good service. Fitters did a great job - very efficient, friendly and tidied up after themselves. Would definitely recommend.
