Aluminium windows fitted across Cardiff & CF10
Capital city — everything from Edwardian conservation-area bays to glass-fronted Bay apartments. That mix is why no single aluminium windows spec works for every Cardiff address — a Cyncoed terrace needs different reveals to a newer Cathays estate. We survey first, recommend the right powder-coated RAL finish, and quote in writing. 10-year powder-coat guarantee, 2-year fit warranty sits behind every job.
Owner occupiers doing the whole property in one go
Why aluminium windows look different to owner occupiers doing the whole property in one go
Whole property work is a different purchase to a single replacement. You are buying two to four days of disruption, a matched set of frames and one point of contact, so this page concentrates on those three things.
What this buyer actually needs from us
- Matching frame colour and hardware finish across the whole property
- A programme that keeps the house lockable and weathertight every night
- The bay-corner post is set with a laser level across both faces before the outer frames are trimmed to fit.
- The crew takes the old glass off site in a labelled sack that day, not a skip left on the drive.
Full public liability insurance and a written two year fitting guarantee on the package

How we build aluminium windows
Structural openings checked for square, aluminium frames mechanically fixed to the substrate, perimeter sealed with low-modulus silicone.
- • thermally broken aluminium profile
- • powder-coated RAL finish
- • 28mm warm-edge spacer units
- • concealed espagnolette locking
Guarantee: 10-year powder-coat guarantee, 2-year fit warranty.
What we typically find on aluminium windows surveys around here
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.
- ·The glazing spacers between panes carry the visible desiccant snowfall that gives away a blown unit.
- ·The multipoint keeps have worn a shallow groove where the hooks now catch — closing needs a lift-and-pull.
- ·The old timber back door has a live rot pocket at the bottom hinge that reads soft to a screwdriver tip.
- ·Every kitchen window handle has been replaced twice in ten years — a sign the espag is going, not just the handle.
- ·Two units have the classic dust ring inside the sealed gap, meaning the perimeter seal has been breached for at least a year.
- ·The internal beads pop out with a chisel and a tap, but the external glazing gasket is bonded solidly to the frame.
- ·The bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.
- ·The georgian bar between the panes has come detached from the top spacer on one unit.
- ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
- ·The letterplate flap spring has gone slack and the flap now hangs open in a light breeze.
- ·One sash locks by lifting a nail out of the frame — a bodge from a decade ago that everyone forgot about.
- ·The manufacturer's kite mark on the corner of the glass is late-90s vintage, which explains the thermal performance.
- ·The frame drainage slots at the bottom are clogged with debris, so rainwater sits inside the chamber.
- ·The catch keep for the bathroom window has been packed out with a folded matchbox to make the sash lock.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
Why residents are booking aluminium windows right now
- ·The homeowner is planning a garden studio and wants the patio doors to bookend the view when it's finished.
- ·The owner wants the job to finish clean — no leftover offcuts in the skip on the drive, no sealant on the render.
- ·The homeowner is selling within eighteen months and wants the front elevation to photograph well for the listing.
- ·The buyer is furnishing the property for short-term let and wants a five-year cosmetic warranty on the door slab.
- ·The buyer wants a genuine Which? Trusted Trader install, not a subcontracted crew running the badge.
- ·The resident wants the front door to sound solid when it closes — a hollow slap does not read as secure.
- ·The homeowner is expecting a Grandchild to stay for extended visits and wants the guest room genuinely warm overnight.
- ·The owner has watched a neighbour's crew leave debris behind and wants a written cleanup expectation on the quote.
- ·The resident wants the whole property warm to bare feet on a January morning — the frames are the last variable.
- ·The owner wants the frames to disappear visually and let the view do the work.
- ·The owner has scaffolding booked for a re-render and wants the frames sequenced around the render trades.
- ·The buyer wants the frames branded with the manufacturer's paperwork stapled to the frame chamber for the next owner.
- ·The owner wants the front door to feel expensive to close — the weight, the sound, the drop of the latch.
- ·The buyer wants the sound of the sea audible but the wind noise gone.
- ·The owner has an ageing parent visiting for extended stays and wants the guest bedroom warmer than it currently is.
- ·The owner is done paying to service failing 90s uPVC every couple of years and wants the whole set replaced together.
How our fitters actually do the work
- ·The old broken glass is bagged in a labelled sack, not tipped loose into a general skip.
- ·The manufacturer's serial-number label on the new frame is peeled off, not left to yellow on the glass for years.
- ·The perimeter tape between frame and reveal is a compressible foam tape, not a plain butyl strip.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
- ·The frame is protected with a low-tack film across any face a tool might touch during the fitting hour.
- ·The friction stay screws are torque-limited, not driven at full trigger — over-driven screws strip the stay chamber.
- ·The keeps for the multipoint are set with the door open and the position marked, not adjusted by eye once the door is closed.
- ·Sealant is a single continuous bead run at the perimeter, not overlapped in six-inch runs.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise, checked with a spirit-level lip.
- ·The trim between the frame and the plaster line goes on last, after the sealant has set and been proven leak-tight.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The internal architrave is scored along its length with a fresh blade before removal, so the wallpaper does not tear back.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
FAQs — aluminium windows in Cardiff
How do you reach jobs in Cardiff from your base?+
10 miles from base, A470 the whole way — Cardiff installs run as smoothly as our home patch — typically a short run via A48.
Why replace the whole set rather than one-by-one in a Cardiff home?+
Because chunky uPVC bars that block daylight in narrow valley terraces, and dated 70s aluminium that cold-bridges and ices up internally rarely stays isolated — once one unit goes, the rest follow within a few years. Doing it once means matching frames across the elevation and one trip for our team into CF10.
How long does a aluminium windows install take in a Cardiff property?+
1–2 days for a typical rear elevation, longer for full-house. Most of the Edwardian and Victorian bay-fronted houses in Cathays and Roath we see in Cardiff fit our standard schedule with no surprises.
Do you do commercial aluminium windows for sites near Cardiff Bay, Capital Business Park?+
Yes. We've worked across Cardiff Bay, Capital Business Park and the Llanishen industrial belt, supplying the same thermally broken aluminium profile build we use on residential. Commercial quotes include site access notes and out-of-hours options.
Will aluminium windows suit the older Edwardian and Victorian bay-fronted houses in Cathays and Roath common around Cardiff?+
Slim sightlines maximise daylight in tight Edwardian openings, and powder coat shrugs off coastal salt and valley rain. We've installed dozens in Cyncoed and Llanishen alone.
Do I have to use the same specification in every room?+
No, and it is usually cheaper not to. Triple glazing where noise or cold is the real complaint, A rated double elsewhere, obscure glass in bathrooms. We price the options side by side at survey.
Will the house be secure overnight during a full replacement?+
Yes. Only one elevation is open at a time and every opening we start is finished, glazed and locked before we leave for the day.

Faults we fix before recommending aluminium windows
Handles are a cheap wearing part — the trick is matching spindle length, backset and screw centres so it fits first time.
Friction stays are consumable — when they corrode or bend, the sash drops out of square and everything else starts to fail with it.
Asymmetric glass thickness and a good frame seal cut traffic noise; simply adding a third identical pane often doesn't.
Yellowing is cosmetic and treatable; splits at the welded corners are structural and aren't.
