We recently used Crownhill Glass Ltd for a window repair, new window installation, and a brand-new front door, and the whole experience was fantastic from start to finish.
The team was professional, friendly, and punctual, and the quality of workmanship was excellent throughout. The window repair was completed quickly and to a very high standard, while the new windows have completely improved the appearance and comfort of our home. The new front door installation was equally impressive — it looks amazing and was fitted perfectly with great attention to detail.
Communication was excellent from the initial quote through to completion, and everything was left clean and tidy afterwards. You can really tell the team takes pride in their work and customer service.
Highly recommend Crownhill Glass Ltd to anyone looking for reliable, professional, and high-quality glazing and installation services. We would definitely use them again!

Misted or Blown Double Glazing?
One of the most common issues for homes and commercial buildings is fogged or misted windows.
