6 windows in a first floor flat
The team from Harp did a great job . From providing all the info needed to comply with the landlord’s licensing requirements to installation . The windows look lovely and the guys did an amazing job with so little mess. Very pleased indeed . Given the windows industry suffers a bit in terms of reputation , it’s been a pleasure lovely to deal with knowledgeable, good people before and during the installation . Thank you - we are really pleased !
Bifolds and patio doors
Excellent service form start to finish. Other companies had a 8-10 week wait, garl had our bifolds with us after 2weeks. The men fitting the doors where so friendly and helpful they got on with the job and tidied everything up and even offered to come back and seal the doors when our other work had been completes 10/10 service and quality
All new windows and back door
What fantastic service I have received from the start of engaging with Harp until completion of the job. Everyone was an absolute pleasure to deal with and the windows look great - the left so little to sort out and cleaned up so nicely. I would highly recommend Harp to anyone!
We have used Harp Windows previously for windows and doors which is why we used them again to replace our old patio doors, excellent job again, sturdy doors fitted well by experienced fitters, would highly recommend.
Replacing 4 sets of windows and one patio door
Excellent job. The two installers seemed to enjoy their work. Clean, quick, immaculate repairs to any damage. All windows and door open easily. Looks really good. Only 2 concerns: 1) they didn't wear ear defenders during noisy work, or masks to protect against fumes from the sealant. 2) the cavity wall insulation was made of tiny styrofoam balls. They didn't lay down a tarp outside, so the balls went all over the grass. I tried to sweep up but will never get them all. (My vacuum doesn't reach round the side of the building!)
Reply from Harp Windows Ltd
Thank you for your great feedback , it is very much appreciated and we are delighted you are so happy with your new windows and door. To quickly address your concerns as listed: as a general rule ear defenders are not commonly used by window installers in the trade. It is not our policy to insist on installers wearing protective masks when applying sealant – this is down to each individual installer’s personal choice. I can only apologise for the inconvenience of the Styrofoam balls in this instance, unfortunately they are notoriously difficult to control, but thank you for bringing it to our attention. In the meantime, if we can be of any further assistance, please don’t hesitate to get back to us at any time.
