Local Experts
Doors, windows and glass for Coventry homes
CGW Installations is a door and glazing installer based in Coventry, working from the south of the city. Coventry is home, so a survey, fitting day or follow-up visit here is never far for us.
We specialise in composite door installation in Coventry, with a particular focus on Rockdoor. We're a Rockdoor Trusted Installer, and in April 2024 Rockdoor named one of our jobs, a double Georgia door set in Agate Grey, its Installation of the Month.
Every job is owner-led and fitted by an NVQ-qualified carpenter with more than 25 years in the building industry.
Why This Area
Why Coventry is our home patch
Because we're based in the city, it's easy for us to come out and measure up, then come back for the fitting at a time that suits you. If something needs adjusting after the job is done, we're close by.
Coventry homes range from older terraces to 1930s semis and newer estates, and the doors and windows on them vary just as much. We look at the opening, the frame and the brickwork around it before recommending anything, so you get a repair or replacement that suits your house rather than a standard answer.
What We Do
The work we do around the city
For new front and back doors, Rockdoor installation comes with Rockdoor's 10-year manufacturer warranty where it applies, and we also offer composite door installation from other manufacturers.
If you already have a Rockdoor that's sticking or hard to lock, our Rockdoor repairs and maintenance service can usually put it right without replacing the door.
We also handle individual window installation, glass replacement for misted or broken sealed units, bifold door installation for extensions, and silicone sealant application around frames, baths and showers.
Good To Know
Before you change a door or window in Coventry
Replacing an external door or window has to meet Building Regulations. We're Certass accredited, so we can certify the work ourselves and you get a certificate once it's fitted, with no separate building control visit to arrange.
If your home is listed or sits in one of the city's conservation areas, check with Coventry City Council before changing how the front of the house looks. Our blog post on whether you need building control approval to replace a front door explains the rules in more detail.
