  • Barrels

At Three Counties, we use only the highest quality materials and construction methods. That’s why we’re confident in offering a two-year guarantee on all mechanical parts.

5-Year Glass Guarantee

The glass guarantee covers the glass and glazing against:

  • Condensation between glass panels

Your view of the world outside should always be clear and beautiful. We understand this, which is why we offer a generous five-year guarantee on the glass used in our installations. This covers issues like condensation between the panels, ensuring that your view remains crystal clear.

Whether you’re gazing out at your garden from your new conservatory or enjoying the natural light that floods through your windows, you can trust that the glass in your Three Counties installation is designed to stand the test of time.

10-Year Frames Guarantee

  • Discolouration

Frames are not just structural components; they also contribute to the aesthetics of your home. Over time, discolouration can be a concern for many homeowners. We put your worries to rest by offering an impressive ten-year guarantee against frame discolouration.

Our frames are designed to maintain their pristine appearance, even in the face of changing weather conditions and the passage of time. This commitment to quality ensures that your home’s windows, doors and conservatories from Three Counties will continue to look its best for years to come.

We recently decided to replace our front door, and could not be happier with the result! Thanks so much to Kate, for her time and understanding. Cannot say enough good things about the installation, and Cameron was tidy and efficient. It's been a pleasure to work with Three Counties recently, doors and windows. Many thanks!

Excellent service!! We had 21 windows and 3 doors installed and very happy with it all. The process from start to finish was stress free and Ron and Lee who installed the windows and doors were great. Would definitely recommend!

Just had my tatty old windows replaced by Three Counties, and it’s been a highly professional job from start to finish. Communication from the administration team was prompt and courteous at all times, and installation ended up being much quicker than advertised projections. Installation was without issue and the lads who did the work were amenable to my requirements and did an excellent job. Very happy with the entire process. Three Counties were recommended to me by friends and I can certainly now recommend them to others.

Bought two new windows and a new front door from Three Counties, was very impressed with the attitude of all staff, who were friendly and informative. Price was good, and installation completed without a hitch - very happy with the final product, and would definitely use again.

We have just had all our windows (18) replaced, french doors (20 and side panels (2) by Three Counties. We could not be more pleased with their workmanship and the finished product. They left the property incredibly clean after each day, and this despite the messy nature of ripping out old windows and frames. We were kept informed at each stage and a minor snagging issue was resolved promptly and efficiently after installation. A first class service. We would not hesitate to recommend Three Counties.

Three Counties have now installed several windows and doors on our house and they're always my go-to company. I used another before I discovered them and they let me down, but I absolutely cannot fault Three Counties. From the moment you contact them they're courteous and professional, and they keep in touch with timescales and installation times. Friendly installers too, who go above and beyond. You'd think all this great service would cost more but they beat other companies on price. Highly recommended and trusted, I'd never go anywhere else now.
