Compliant Window & Door Fitting

Fully Guaranteed and Insured

Designed to Fit your Needs
A tired entrance does more than date your façade — it can leak heat, stick in bad weather and leave you second-guessing security. Our replacement doors solve all three. We design and install made-to-measure systems for front and back doors that feel solid, close cleanly and keep draughts out, with colours and glass that look like they were chosen for your home (not the catalogue). From one-off replace front door projects to full sets with sidelights and top lights, we handle everything from survey to sign-off with clear communication and tidy workmanship.
Upgrading a door is about the system: insulated slabs or thermally broken frames, A-rated glazing in any panels, compression seals that stay tight, and hardware set so the lock engages positively without forcing. Get those right and the difference is instant the first evening you lock up.
If two or more of these are showing, door replacement usually beats patch repairs on cost and comfort over the long term.
We replace every common entrance style with specifications tuned to British weather and everyday use:
Whichever route you choose, we coordinate colours and hardware with your existing windows and roofline so everything reads as one design.
Your front door sets the tone for the entire elevation. We help you specify:
With a measured survey and made-to-measure manufacture, gaps are even, thresholds sit right and the finish looks intentional from every angle.
Rear doors work harder than the front: pets, shopping, recycling, muddy boots. We specify:
Prefer a full-glazed feel for the kitchen? We’ll balance light with etched privacy glass so the room stays bright without feeling exposed.
A modern door stops heat loss where it matters. Expect:
The pay-off: steadier temperatures and fewer cold spots by the entrance — even on blustery evenings.
We fit protection that works quietly in the background:
From the kerb you see clean lines, not oversized ironmongery.
Go classic, modern or heritage:
We’ll bring sample boards to the survey so you can compare finishes in natural light.
If your uPVC door has a single failed unit or a tired handle, a targeted repair can extend its life. When frames are distorted, multiple panes have failed or seals have perished generally, it’s time to replace uPVC door. A new, A-rated door upgrades insulation, security and looks in a single, tidy project — and avoids years of piecemeal fixes.
Like-for-like replacement external doors rarely need planning permission, but they must meet Building Regulations for thermal performance and safety glazing. We handle compliance and provide the paperwork you’ll need for future sales. If you’re changing the opening size or working in a conservation-sensitive area, we’ll advise on sympathetic designs and any permissions.
We specify room-by-room so the door serves how you actually live.
Often a single morning or afternoon including removal, fitting, sealing and tidy. Sets with side panels or making-good can take longer; we’ll confirm after survey
Modern skins and foils are UV-stable. With simple, non-abrasive cleaning, deep tones like Anthracite or Black keep their colour for years.
Yes. We coordinate colours, grains and hardware so the elevation looks designed, not pieced together.
Yes — detailed correctly, they balance accessibility and weathering. We set drainage so water moves away from the opening.
We’ll bring sample boards and photos of installed doors to your survey, and sketch options so you can compare looks in your actual opening.
Share a couple of photos and what you’d like to improve — warmth, quiet, appearance or all three — and we’ll design a replacement door that does the lot without fuss. Clear options, considerate fitting and support that sticks around.
