Period Detail. Modern Performance.
The same flush sash platform, finished with authentic Georgian or astragal glazing bars that make the period look. The sash closes fully within the frame like traditional timber joinery, in keeping with conservation streets, with A+ energy efficiency, triple glazed options and a 10-year guarantee.
Crafted for period character.
Made to measure in the UK. Authentic Georgian and astragal bars over a flush timber-look sash, and four good reasons it belongs on cottages, terraces and conservation streets.
Authentic period detail
Georgian and astragal bar layouts replicate traditional joinery, and the sash sits flush in the frame just like the original timber windows.
Conservation friendly
Flush contours and traditional bar layouts satisfy most conservation officers, with woodgrain foils to match the original joinery.
Modern comfort behind the look
An A+ rated multi-chamber profile keeps the warmth in, with acoustic glazing options to quieten busy period streets.
Safe & secure
Multi-point locking comes as standard with PAS 24 available. Security engineered in, for total peace of mind at home.

How long does installation take?
Most window installs are completed in 1-2 days. Doors typically take 1-3 days depending on threshold work. Full-house or multi-room replacements run 3-7 days. We give you a precise schedule at the survey stage so you can plan around it, no open-ended jobs.
Is the installation FENSA-registered, and do I get the certificate?
Yes. Apex Glazing is FENSA-registered (Reg 40373). On completion you receive a FENSA certificate, which satisfies Building Regulations Part L compliance and removes the need for separate council approval. Certificates are issued within 30 days and stored in your FENSA online account for future house sales.
What warranty do I get?
10-year manufacturer warranty on the product itself (frame, glass seal, hardware) plus a 12-month workmanship guarantee from us on the installation. We've been trading since 2005 with 6,340 completed projects and a 5.0-star Google rating, we'll come back if anything's not right.
Do you remove and dispose of the old windows or doors?
Yes, removal of existing units, safe disposal at a licensed waste facility, making good of internal and external reveals, and a thorough final clean-up are all included in the quoted price. There are no extras for skip hire, scaffolding, or waste removal.
Can you match existing windows for a phased replacement?
Yes. We can RAL colour-match the new frames to your existing units, replicate sightlines, glazing bar layouts, and hardware style to keep a phased replacement consistent. Bring photos to the survey, or we'll come and measure the existing windows so the new ones blend in seamlessly when fitted alongside.
