Doors, glazing and sealant work in Nuneaton
CGW Installations is a door and glazing installer based in Coventry, working across Nuneaton. We supply and fit Rockdoor and other composite doors, individual windows and bifold doors, replace failed glass and renew silicone sealant.

Why This Area
Small jobs done properly
Sealant is easy to overlook until it fails. Once it splits, shrinks or goes mouldy around a window frame, door, bath or shower, water can get behind it and cause damp or damage.
We cut out the old sealant, clean and prepare the joint, and apply new sealant in a colour that suits the surface around it. Our post on the signs you need sealant replacing explains what to look for. We give a small sealant job the same care as a new front door.
What We Do
What we do in Nuneaton
Our silicone sealant application service covers windows, doors, baths and showers. For new entrances, Rockdoor installation includes Rockdoor's 10-year manufacturer warranty where it applies, and our composite door installation service covers other brands.

Good To Know
Before you replace a door or window
Nuneaton is in Nuneaton and Bedworth Borough. If your home is listed or in a conservation area, check with Nuneaton and Bedworth Borough Council before changing the look of your front door or windows.
Replacement doors and windows also have to meet Building Regulations. We're Certass accredited, so we certify our own work and you get a certificate once it's done. Our post on whether you need building control approval to replace a front door explains more.
