Cardiff, CF10

Patio doors fitted across Cardiff & CF10

Capital city — everything from Edwardian conservation-area bays to glass-fronted Bay apartments. That mix is why no single patio doors spec works for every Cardiff address — a Cyncoed terrace needs different reveals to a newer Cathays estate. We survey first, recommend the right toughened safety glass to BS EN 12150, and quote in writing. 10-year product, 2-year fitting sits behind every job.

Owner occupiers replacing one door or one window

Why patio doors look different to owner occupiers replacing one door or one window

A single replacement is a half day job for us and a whole day of your time, so the useful detail is arrival window, how the old frame comes out, and how the new one is made good inside and out.

What we build into the quote for you

  • The old unit removed and taken away the same day
  • Making good inside so there is no decorating job left behind
  • The client's Wi-Fi router near the door is checked for a signal drop after the composite slab is fitted — a rare case, but worth confirming.
  • The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.

Reviews from customers who booked one door or one window and were not upsold

Common in Cardiff
  • Heritage-friendly frame profiles in conservation streets
    Our patio doors address this with thermally broken aluminium or reinforced uPVC.
  • Traffic noise on the A48 ring
    Our patio doors address this with thermally broken aluminium or reinforced uPVC.
  • Single-glazed bays losing heat in tall Victorian rooms
    Our patio doors address this with thermally broken aluminium or reinforced uPVC.

What we typically find on patio doors surveys around here

  • ·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
  • ·The letterbox opening is not draught-proofed at all — a candle held two feet away flickers in a light wind.
  • ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
  • ·The bay-corner post has bowed by about 4mm across two metres — visible only if you sight along it.
  • ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
  • ·The letterplate is a straight through-plate with no anti-snap flap — visible from outside in the hallway.
  • ·The bay corner post has never had its structural bracket — a common corner-cutting shortcut a decade ago.
  • ·There is a live crack running from the top corner of a bay-window pane where the frame has been out of square since installation.
  • ·Original security bolts on the ground floor sashes are seized in place and no longer key-lockable.
  • ·The friction stays are the wrong hand for the sash — a previous swap fitted left-hand stays on a right-hand window.
  • ·The concrete cill under the door has heaved by 3mm across the two-metre span, tilting the whole threshold.
  • ·The mid-rail on the composite door is bowed outward at the middle by 2mm — a slab-warp symptom.
  • ·The cill end-cap has fallen off and the cill chamber is now a home for insects.
  • ·The front door has been painted three times without stripping — the paint film is now stopping the door closing at the top.
  • ·The internal glazing bead across the top of the bay lifts out completely with fingernail pressure.
  • ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.

Why residents are booking patio doors right now

  • ·The buyer is done with the sound of the frames rattling in a gale.
  • ·The buyer is buying the property specifically for the garden and wants a bi-fold that opens the whole rear elevation.
  • ·The owner wants the master bedroom quiet enough for a night-shift partner to sleep past 11am.
  • ·The homeowner is preparing the property for a smart-home installation and wants sensor pockets designed into the reveals.
  • ·The owner has watched a neighbour's crew leave debris behind and wants a written cleanup expectation on the quote.
  • ·The buyer wants the whole ground floor to feel more connected to the garden without losing the wall.
  • ·The buyer wants the front door delivered pre-hung and pre-glazed on the same date as the frames.
  • ·The homeowner is planning a loft conversion next year and wants the windows sorted before scaffold cost is priced.
  • ·The homeowner is 68 and wants a threshold that will still be usable in ten years without a step.
  • ·The buyer wants a survey that says no to things when they don't fit, not just yes to everything they ask for.
  • ·The owner is preparing the elevation for a specific street-photo listing and wants the finish to be photographable in raking morning light.
  • ·The resident wants the kitchen brighter in the mornings without losing the privacy from next door's back garden.
  • ·The buyer wants the whole job done by one team who own the outcome — not designed in one place and fitted in another.
  • ·The buyer wants a genuine step-up in security, not a marketing claim — PAS24 tested, not PAS24 marketed.
  • ·The resident has been quoted for solar and does not want the roof work to happen before the windows do.
  • ·The owner wants the property to look less like a rental and more like a home, and the front door does most of that work.

How our fitters actually do the work

  • ·The manufacturer's kite mark on the corner of the glass is left in place at handover — proof of spec for the next owner.
  • ·The lead fitter leaves a handwritten note of anything the client should watch in the first month, not a printed generic checklist.
  • ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
  • ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
  • ·The lock cylinder is measured to sit flush with the escutcheon plate — a proud cylinder is a snap risk.
  • ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
  • ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
  • ·The trickle-vent covers are set with their vane orientation matched across a bank of windows for visual consistency.
  • ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
  • ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
  • ·The manufacturer's serial-number label on the new frame is peeled off, not left to yellow on the glass for years.
  • ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
  • ·Cylinders come out of the box, get numbered, and are the last thing fitted, so a lost cylinder does not stall the day.
  • ·The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.
  • ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
  • ·The perimeter airtight tape is applied over the frame flange in a single unbroken run around all four sides.

FAQs — patio doors 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 tired 80s sliding aluminium doors that stick, lose heat and rattle in the wind 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.

What guarantee do I get when you fit patio doors in Cardiff?+

10-year product, 2-year fitting. We're insured to work right across Cardiff Council's area, and you have one named contact from quote to snag.

Do you do commercial patio doors 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 or reinforced uPVC build we use on residential. Commercial quotes include site access notes and out-of-hours options.

Is it cheaper to repair the existing frame?+

Often, yes. Hinges, handles, gearboxes and single sealed units can all be replaced without touching the frame. We quote the repair first when the frame itself is sound.

Will one new unit match the older frames already fitted?+

We match profile, colour and hardware finish as closely as the current stock lines allow, and we will tell you honestly at survey where an exact match is not possible.
