Purchased new windows for a job we are doing for a customer in Portsmouth. These guys are great. Very responsive and know what they are talking about. They also keep up with building regulations to make sure everything they supply meets the standard. Thanks!!!!

I have been using Horizon windows and doors on our properties and those of customers for over 10 years now and never ever had anything other than 1st class service and quality - light tunnels, roof lights, french and sliding doors, windows in plain, woodgrain and painted finishes and the replacement of blown sealed units originally fitted by others. Thoroughly recommend! Great company with 1st class professional staff.

Supplied and fitted a set of bi-fold doors in our new extension. Good workmanship and took away all waste afterwards. The doors look great and its really finished off our new patio area. Thumbs up ?

We recently had bifold doors and windows installed and we couldn’t be happier with the results! From start to finish, their team was professional, knowledgeable, and incredibly helpful.

The quality of the doors and windows is outstanding and clearly built to last. The installation process was smooth and efficient, with great attention to detail. They kept us informed throughout, ensuring everything was perfect. Highly recommend to anyone looking!

I used horizon for windows for my extension, we had a great service from start to finish we are using them again later in the year to replace the existing house windows after seeing the quality of the ones for our extension, super pleased with them.
