uPVC & aluminium windows
Casement, flush sash, tilt & turn, bay and sliding sash. A-rated double or triple glazed.
Luton · Bedfordshire · North London
We're a small Luton-based installer specialising in made-to-measure uPVC and aluminium windows, bi-fold doors and composite front doors. One team surveys, manufactures to your sizes and fits — so nothing gets lost between trades.

What we supply and fit
Nothing here is off-the-shelf. Every frame is manufactured to the sizes we take off your opening, in the colour and finish you choose.

Casement, flush sash, tilt & turn, bay and sliding sash. A-rated double or triple glazed.

Two to seven panels, slim 100mm sightlines and a low threshold that sits almost flush.

48mm composite front doors, uPVC back doors and French doors, all on multi-point locks.

Roof lanterns for flat-roof extensions and inline sliding patio doors for wide openings.

Why homeowners pick us
You deal with the same people from the first measure to the final adjustment. There's no call centre, no commission-only salesperson and no price that mysteriously halves if you sign tonight. We quote once, in writing, and that's the price.
Specification
Not upgrades, not optional extras. This is the baseline on every job we quote.
Low-emissivity glass, warm-edge spacer bars and argon fill. Typical whole-window U-value from 1.2 W/m²K, or 0.8 with triple glazing.
Multi-point shootbolt locks, anti-snap and anti-bump cylinders on doors, internally beaded frames so glass can't be removed from outside.
Multi-chambered profiles with twin gaskets and drained, ventilated glazing rebates. They stay dry and they stay quiet.
Part F of the Building Regulations changed in 2022. We fit compliant background ventilation and tell you where it's needed.
Anthracite grey, black, cream and Chartwell green are our most-asked-for. Aluminium can be powder coated to any RAL, dual-colour included.
Toughened or laminated glass in every critical location — doors, side panels and anything low-level — as Part K requires.
How it works
From your first call to us clearing up and handing over the paperwork.
Tell us what you're after. If you have rough sizes or photos, even better — we can often give a ballpark figure on the phone.
We measure every opening, check the structure above it, talk through frame styles, colours and glass, and leave you samples to look at.
An itemised quote within 48 hours. Approve it and your frames go into manufacture — usually two to three weeks for uPVC, three to four for aluminium.
Most houses are done in one to two days. We take the old frames away, make good, hand over your guarantee and register the work for Building Regs.
The job we get asked for most
A bi-fold lives or dies on the survey and the threshold. Get the opening out of level by a few millimetres and you'll be shouldering panels shut by the second winter. We laser-level the aperture, check the lintel can carry the span, and set the track in a bed of sealant so water drains out rather than pooling under the rollers.
The result is a door that opens with one hand, locks without lifting, and folds back to leave you 90% of the opening clear.

In their words
Recent jobs across Luton, Dunstable, St Albans and Barnet.
Three-panel bi-fold across the back of the kitchen. Quoted properly, arrived when they said, and the threshold is genuinely flush so the wheelchair goes straight out.
Nine windows and a composite front door in two days. They dust-sheeted the whole hallway and I honestly couldn't tell anyone had been in. Front of the house looks like a different property.
We're in a conservation area so the flush sash in Chartwell green was the only thing planning would accept. They knew that before I did and sorted the paperwork side too.
Had three quotes. Theirs wasn't the cheapest but it was the only one that listed the glass spec and the U-value in writing. That told me everything.
Where we work
We're based in Luton and most of our work sits within about 30 miles of it. That's deliberate — it means we can get back to you quickly if something needs adjusting, rather than treating aftercare as someone else's problem.
Not sure if you're in range? Ring us. If we can't help we'll usually know someone who can.
Common questions
It depends on size, material, colour and glazing, so anyone quoting a firm figure before measuring is guessing. As a rough guide, a standard uPVC casement in white sits at the lower end, a coloured flush sash in the middle, and slimline aluminium at the top. Triple glazing typically adds 15–25%.
We'll give you a ballpark over the phone if you have approximate sizes, then a fixed written price after the survey. No deposit is taken until you've seen that price.
uPVC gives you the best thermal performance per pound and needs almost no upkeep. It's the sensible choice for most replacement windows.
Aluminium is stronger, so the frames can be much slimmer — you get noticeably more glass in the same hole in the wall. It's the right call for bi-folds, large sliding doors and anywhere you want a crisp, modern line. It costs more.
Replacement windows and doors are covered by the Building Regulations, and the installation has to be certified. We handle that and you get the certificate for your records — you'll need it when you sell.
Planning permission normally isn't required for like-for-like replacement, but it can be if you're in a conservation area, the property is listed, or you're changing an opening size. We'll flag it at survey stage if it applies to you.
Manufacture is the long part: two to three weeks for uPVC, three to four for aluminium. Fitting is quick. A typical three-bed house of windows is one to two days, a single bi-fold is usually a day.
We work one opening at a time so the house is never wide open, sheet the floors and furniture, and take every old frame and offcut away with us.
Frames, sealed units and our workmanship. That includes misting or blown double glazing, failed hinges and handles, and anything that turns out to be down to how we fitted it.
Wear items and accidental damage aren't covered, and neither is glass breakage after handover. Full written terms come with your quote so you can read them before you commit.
Yes. Misted units, dropped or dragging doors, broken hinges, failed handles, snapped locks and worn gaskets are all straightforward fixes and far cheaper than replacing the whole frame.
If a frame is genuinely past saving we'll tell you that rather than sell you a repair that won't last.
