Casement windows
The classic side-hung window — clean lines, excellent ventilation, available in flush or storm profiles.

Browns supply and fit made-to-measure double and triple glazed windows in uPVC, aluminium and timber-effect frames. Every unit is internally beaded, A+ rated and backed by a 10 year insurance backed guarantee.

We start every window project with a free at-home survey. A Browns surveyor — never a salesperson — measures up, talks through frame styles, glass choices and ironmongery, and gives you a fixed price within one working day.
Frames are manufactured to your exact reveals so there's minimal making good when we fit. Our in-house installers remove your old units, fit and seal the new windows, and tidy up properly before they leave.
All windows are FENSA registered on completion. You'll receive your guarantee paperwork through the post a few days later.
