10 Excellent service and quality work

Writing this review 3 years after installation - still very happy with the standard uPVC windows. I can't speak highly enough of Amy, John and the installation team. Excellent communication - they patiently answered all of the questions. Punctual for the quotation appointment and installation - they are very experienced and knowledgeable. Harp Windows removed aluminium windows and the remnants of the bay window bits and replaced with uPVC. They exceeded expectations - they replaced the window ledge with wood, not pvc, as others quoted. Condensation black wall marks - a thing of the past.Verified reviewerJob location: HA210 Fit new UPVC back door.

Overall very good. Apparently I would have been better off ordering a new window at the same time, but in the event the installers worked around this shortcoming in a very professional manner and with great attention to detail.Verified reviewerJob location: WD2510 Replacement windows to front bay and bedroom

Job location: WD23From the moment I made contact with Harp Windows, they were very professional and helpful. John at the showroom listened to what I wanted and delivered exactly that! The two glaziers Rob and Robert are an asset and a real credit to Harp, very tidy, courteous and professional. It was a big job and tough in - 5 degrees and they did not stop, they worked very hard and were very pleasant at the same time! I would not hesitate to use them again, and highly recommend. I’m thrilled with the front of the house! Thank you Harp Windows10 Window unit replacement to a sash

Fantastic service from beginning to end. Local showroom in Watford with a super variety of windows and doors The fitment of the sash for my son's bedroom, best decision. Quality window and beautiful finish Paul and Miles are polite and friendly. Paul is a master at his job and Miles is super when finishing and completion.

I have to say I have been impressed with HARP from start to finish. I was guaranteed the best price from John at the beginning, There was no hard sell or tricks, Just simple and honest. I ordered 1 window to replace my old bay which I was advised would take 6 weeks from ordering. My window arrived slightly earlier than anticipated and was fitted without delay. The fitting team worked in a clean and tidy manner, were punctual and had a great attention to detail.Verified reviewerJob location: WD24

Our Mission:
To provide top quality local installations. We may not be the cheapest out there but we have full confidence in the quality and integrity of our products and our fitting teams. The outward appearance of most replacement windows and doors can be almost identical, but don't be fooled into thinking that all uPVC products are more or less the same!

Here at Harp, we only install top quality products in uPVC, aluminium and timber:
- Rehau uPVC casement windows and doors
- Evolution Storm and Flush timber replacement windows and doors
- English Door Company for our premium range of front and back doors
- Origin aluminium windows, doors and bifolding doors
