Fantastic service from start to finish. We had our old windows replaced with new double-glazed ones and the difference in warmth and noise reduction is incredible. The team arrived on time and worked professionally. Highly recommended. HARRY BROWN

We ordered a custom front door and the quality is brilliant. The fitting team were friendly, tidy and explained everything clearly. The house feels much more secure now. Will definitely use them again. ROSS WILLEY

I needed a roof lantern installed for my kitchen extension and these guys did an excellent job. Clean lines, great finish, no leaks, and the natural light is unbelievable. Worth every penny. MONICA WOOD

Our shopfront glazing cracked after a break-in. They came the same day, secured the area and replaced the glass quickly. Very reliable and polite service – exactly what you want in an emergency. THOMAS WATSON

Brilliant workmanship. They repaired a misted double-glazed window in our bedroom and saved us from replacing the whole unit. Honest pricing and no upselling. Refreshing to see! HARRY BROWN

We had glass balustrades installed on our staircase and the final look is stunning. Super modern and very safe. The installers clearly knew what they were doing and worked with great attention to detail. ROSS WILLEY
