But don’t just take our word for it…

A thorough and professional service on the advice, design, supply and installation of my secondary glazing. Now it is installed it is performing up to my hopes. Its definitely the way to go if you have big windows! Nice to find a company like this.

Great company to work with. We had some secondary glazing put on our bedroom window to combat noise from the main road our flat is on.

Mr Hogg

Secondary glazing put in with the minimum of fuss. Joiners got on with the job cleaning up behind them. Would recommend them to anyone.

Mr & Mrs McShane

Excellent service from start to finish! Very helpful salesman came out (not pushy at all) and explained everything/provided quotes for a secondary window. Window installed yesterday and looks great – guys that fitted the window arrived when they said they would and got the job done with no mess. 5/5 🙂
