Compliant Window & Door Fitting

Fully Guaranteed and Insured

Designed to Fit your Needs
Patio doors are all about light, space and everyday convenience. Modern sliding patio doors give you wide, uninterrupted views with slim frames, smooth-running tracks and strong weather seals — so you can enjoy the garden without draughts or rattles. We supply and install patio doors, including uPVC patio doors and contemporary aluminium sliding doors, made to your exact opening with glass and hardware options that suit how you live.
A great result blends design and engineering: insulated frames, low-E glass, precision rollers, and thresholds that keep the elements out while staying easy to keep clean. We measure, make and fit with care so your doors look intentional, move effortlessly and stay that way for years.
Both deliver excellent performance; the right choice depends on look, span and budget.
We’ll bring samples so you can compare frame depth, colours and handle styles in natural light.
Patio doors should feel as cosy as the rest of the room. Our specifications include:
You’ll notice steadier temperatures and fewer cold spots beside the glass.
Good security can be discreet. Expect:
From the garden you see slim, balanced lines — not bulky bars or bolts.
We design patio doors around your everyday flow:
We’ll map furniture positions and walkways during survey so the main opening lands exactly where you need it.
We specify room by room, balancing light, privacy and quiet.
We coordinate handles, cills and nearby window colours so the elevation feels designed, not pieced together.
Thresholds take the brunt of daily traffic. We set them to:
For busy households, we’ll recommend low-maintenance finishes and hardware that shrug off constant use.
It’s time to consider patio door replacement if you notice:
A modern, made-to-measure set restores easy operation, security and insulation in one project.
Smooth, secure doors start with careful fitting:
We protect floors, remove waste and leave everything tidy at the end of each day.
Like-for-like patio door swaps rarely need planning permission, but installations must meet Building Regulations for thermal performance and safety glazing. We handle the compliance and issue the documents you’ll need for future sales. If you’re widening an opening or working in a conservation-sensitive street, we’ll advise on sympathetic design choices and any permissions.
These five-minute habits keep movement smooth and seals effective.
We’re happy to sketch alternatives and talk through how each option behaves in your space.
Not with modern low-E, argon-filled glazing, warm-edge spacers and tight compression seals. Correct installation is key — we make sure the perimeter is airtight.
Quality tracks are easy to keep clear. A quick vacuum and wipe now and then is enough; rollers are designed to run smoothly over day-to-day dust.
Yes — we can supply a glazed unit with an integrated cat flap or fit one to a suitable panel, keeping security and sealing in mind.
No. With the right running gear and calibration, both glide with minimal effort. Aluminium simply allows bigger panes with slimmer frames.
Absolutely. We coordinate patio doors with existing window colours and door furniture so everything reads as one design.
Tell us about your opening, your view and how you use the room — we’ll design sliding patio doors that feel smooth on day one and still do in five years, with security and insulation built in. Clear options, tidy installation, long guarantees.
