It is so nice to see that local and dependable businesses do exist. I had someone come around to quote me who was a nice genuine lady and not a cheesy sales person. They offered a reasonable price and timescales. I was called the week below they were due to come to decide on what day would be busy. Two gentlemen fitted the windows quickly and efficiently and even cleaned up after themselves. The windows themselves are incredible quality.

Would throughly recommend!

We got new windows with KP, 6 in total, to update our whole house, and we are very pleased with the final result. Within a mere 2 days of initially visiting the showroom in town, we had a member of staff visit our home to provide a quote for the windows, including installation, and we paid a deposit the same day. We went ahead knowing the work should get completed within 6 weeks and every step of the way all members of staff were friendly and helpful. This timescale was adhered to and when the work actually began in our house we had all 6 windows replaced in 1 single day (about 7hours really!). The installation team worked very quickly, professionally and respectful to our property ensuring sheets were laid down inside and they fully cleaned up after themselves when leaving. Our windows looks great, they have given our home an updated/modern look, we already can see and feel the difference since upgrading from our original wooden windows, and the overall buying experience has been very positive! We would absolutely reccomend this business for any of your window/door needs.

KP Windows and Doors are a fantastic, local business that you can rely on. We have used them for replacing double glazing in the past but chose them to replace our very tired, old, creaky main door this time.
Maureen arranged a site visit and listened carefully to our requirements and preferences. She came up with the perfect door! We had this installed last week and it looks stunning. We chose a Chatsworth Green for the outside and white for the inside. The whole dynamic of the kitchen has changed. From being shut behind a solid old brown, creaky door, to a beautiful light door that reflects colours from the cut glass design, the kitchen looks so much bigger! Thank you, KP Windows and Doors!

From start to finish everyone was very helpful!
I had a completely new conservatory, literally bringing it back to basics & starting from scratch!! The end result is fabulous & the glass roof is beautiful, definitely worth it!
The installers did a great job & they were very neat & tidy! Great workmanship!!
Overall I’d highly recommend this company!

✅✅We Wanted a bi-fold door installed in our new extension, the staff were particularly helpful in helping us decide on what was the best option for our size of opening. Ordered and installed with absolute professionalism. Will be using again when we renew our windows! First class local independent retailer ✅✅

Amazing service from start to finish. Really easy and friendly to deal with. The fitters did a great job, and were very clean and tidy on the day. The window looks impressive too. A great job all round.

Review for the front door that you fitted for us on Friday 14th August 2020. The service provided by ĶP Glass to us was a quick and well carried out. The two young men were well mannered and their workmen ship very professional resulting in this beautiful new door and windows with internal blinds. The Blind fitted in the window was adjusted for me on Wednesday by Phil from the blind manufacturer so that I could open it with ease because of my arthritis.

I would highly Recommend both KP and the blind Manufacturer.

Many thanks Chris and Alan Heels.
