I recently had Lancashire Double Glazing install new sliding patio doors in Anthracite Grey and I couldn’t be happier with the result. From start to finish, the process was seamless: The Anthracite Grey looks incredibly modern and has completely transformed the look of my house. It’s a sleek, high-end finish that really stands out. The sliding mechanism is butter-smooth. You can feel the build quality every time you open them—very solid and excellent at keeping the heat in. The team was professional, tidy, and efficient. They arrived on time, got the job done with minimal disruption, and left the area spotless. If you’re looking to upgrade your home, I highly recommend LDG. Great service and a fantastic product!

Great service from start to finish. Returned quickly to resolve minor unnoticed issue after fitting of French doors was completed. Would recommend and definitely go back to them if I need anything else. ☺️

Excellent service from start to finish We used this glazing company for a full premises installation in 2025, including all doors, windows, and a skylight. From the very beginning, the office staff were professional, helpful, and well-organised, keeping us informed throughout the process and answering all our questions clearly. The fitters were excellent — punctual, skilled, tidy, and very respectful of the property. The workmanship is of a very high standard, and everything was fitted perfectly. The quality of the materials and the attention to detail really stand out. The whole job was completed smoothly and on time, with no issues at all. Highly recommended for anyone looking for reliable, professional glazing services with a great team both on site and in the office.
