Getting casement windows right in Grantham
Casement windows are the most common replacement window type in the UK, hinged at the side or top and opening outward for good ventilation. In Grantham, that means working with a Georgian High Street core with Victorian terraces and post-war estates around it. The Georgian frontages on the High Street are listed, so shopfronts and flats above them occasionally need heritage sign-off, but the surrounding residential streets are mostly standard Victorian brick. We quote against the property in front of us rather than a generic price list, so Grantham jobs are measured and priced individually.
Why locals choose us
- A-rated (or better) energy ratings on modern casement units, which helps against heat loss through single-glazed or tired double-glazed originals
- UPVC, aluminium or timber-effect frames depending on the look you want and how much upkeep you’re happy to do
- A Lincolnshire market town, the birthplace of Margaret Thatcher and close to Isaac Newton’s Woolsthorpe Manor, which shapes a fair bit of the Grantham housing stock we work on
- Trickle vents and multi-point locking as standard on new casement units, which matters for both condensation control and insurance compliance
- Free, no-obligation quotes with a written price before any work is booked in

Frequently asked questions
How long does a casement window installation take in Grantham? A standard-sized casement window usually takes 30-60 minutes to fit once the installer is on site; a full house of 8-10 windows is normally done in a single day by a two-person team.
Can I get uPVC casement windows in a conservation area near Grantham? It depends on the specific conservation area rules - some allow uPVC if the profile and glazing bar pattern match the original, others require timber. Check with the local planning department before ordering.
What’s the difference between top-hung and side-hung casement windows? Side-hung casements open outward like a door and give the widest opening for ventilation; top-hung casements (often called awning windows) hinge at the top and can stay open a crack even in light rain.
