Composite Doors in Caerphilly, Supplied and Fitted
Caerphilly is our home patch. We fit composite front doors right across CF83, from the terraces off Bedwas Road and Nantgarw Road to the newer estates at Trecenydd, Energlyn and Llanbradach, and out to Bedwas, Machen and Abertridwr. Most jobs are a single day, the old door goes with us, and the price you agree is the price you pay.

Why Caerphilly homeowners choose us
Owner occupiers doing the whole property in one go
Why composite doors 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.
The things worth checking before you accept a price
- An itemised written price so single openings can be added or dropped
- Matching frame colour and hardware finish across the whole property
- The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.
- The internal cill is scribed to the reveal, not just butted and caulked over the gap.

Composite door styles we fit
A composite door is a 48mm solid timber and foam core wrapped in a glass reinforced plastic skin. That build is what lets it hold a colour, resist warping and take a proper multi point lock without flexing. The style you pick changes the slab, the glass aperture and the hardware, not the core.
- Solid slab, no glass at all, the most secure and the warmest option
- Half glazed with a single central aperture, the most popular choice on Caerphilly terraces
- Four pane and six pane cottage styles for older stone fronted properties
- Door with one or two sidelights, which suits wide Edwardian and 1930s openings
- Door with a top light or transom above, used where the opening is taller than a standard 2100mm slab
- Arched glass and stable door variants for cottages and converted properties
Colours and finishes
Composite skins are coloured through the surface layer rather than painted on, so a scratch does not show a white line underneath. Anthracite grey and black are the two we fit most, with navy close behind. Dual colour is standard on most ranges, so you can have a strong colour outside and white inside where the hallway is small and needs the light.
- Anthracite grey, jet black, navy blue, racing green, chartwell green, duck egg, red, cream and white
- Woodgrain or smooth surface texture on most colours
- Dual colour inside and out at no structural cost
- Hardware in brass, polished chrome, satin chrome, matt black or graphite
- Matching letterplate, knocker, spy hole, numerals and handle sets
Glass options
Glass is where a door stops looking like everyone else's. All our glazed doors use toughened safety glass as standard, and every glazed unit is double glazed with a low emissivity coating. Obscure glass is graded 1 to 5 for privacy, and we recommend level 4 or 5 for anything facing a pavement.
- Clear toughened double glazing for doors set back in a porch
- Obscure levels 3, 4 and 5 for street facing front doors
- Decorative leaded, bevelled, sandblasted and stained designs
- Triple glazed door glass where the hallway is cold or the door faces a main road
- Low iron glass where you want the colour of the door to read true through the frame
Security and locking
Security is the part people ask about last and care about most once it is explained. The lock, the cylinder and the hinges do the work, not the slab. We fit a high security multi point lock as standard, with a cylinder that resists snapping, bumping, picking and drilling.
- Multi point lock with hooks, rollers and a deadbolt engaging on lift of the handle
- Anti snap, anti bump, anti pick and anti drill cylinder to TS007 3 star or equivalent
- Reinforced steel or aluminium subframe within the outer frame
- Fixed security hinge bolts on the hinge side so the door cannot be levered off
- Laminated glass upgrade available where the door is out of sight of the road
- Specification suitable for PAS24 requirements where a landlord or insurer asks for it
Insulation and running cost
The foam core is the reason a composite door feels different to touch in January. A typical old timber or early uPVC front door has very little insulation and a poor seal at the threshold, so the hallway pulls cold air through the letterplate and under the door. A modern composite slab with a double sealed frame and a thermally broken threshold cuts that draught out.
It will not on its own transform a heating bill, and we will not claim it does. What it does reliably is stop the hallway being the coldest room in the house and stop the draught you feel on the stairs.
Composite compared with uPVC doors
A uPVC door is a hollow frame with a panel inside it. A composite door is a solid slab hung in a frame. Both are perfectly serviceable, and uPVC is the cheaper option, but they behave differently over ten years.
- Rigidity: a composite slab does not flex when pushed, a uPVC panel can
- Colour: composite colour runs through the skin, uPVC foil can lift at the edges after long sun exposure
- Thickness: 48mm composite against roughly 28mm on most uPVC doors
- Cost: uPVC is typically the cheaper supply and fit, composite costs more up front
- Lifespan: we would expect a composite door to still look right at 15 years, and a foiled uPVC door to look tired sooner
- Both take the same grade of multi point lock, so security comes down to the cylinder either way
What is included in a fitted price
We quote supply and fit as one written figure, so there is nothing added on the day. A quote from us includes the survey, the door, the frame, the hardware, the fitting and the clean up.
- Free site survey and a written quote, no obligation and no pressure
- Removal and disposal of the old door and frame
- New outer frame fitted plumb to the reveal with hardwood packers
- Composite slab, chosen glass, chosen hardware and the security cylinder
- EPDM and silicone sealing inside and out, plus internal trims
- Threshold set and drainage checked so water runs away from the property
- 10 year product guarantee and 2 year fitting guarantee in writing
- Site left clean, old materials taken away the same day
What Caerphilly properties actually need
The housing here is mixed and it changes the door spec more than people expect. The Victorian and Edwardian terraces around the town centre often have a tall opening with a fanlight above, so a standard slab leaves a gap that has to be filled with a top light rather than packed out. The 1930s semis at Penyrheol and Trecenydd usually take a standard 838mm slab with a single sidelight where the porch was widened. The newer estates at Energlyn and Churchill Park are typically a straight swap.
Older stone fronted properties towards Abertridwr and Senghenydd often have reveals that are out of square by 10mm or more. That is not a problem, but it does mean the frame has to be packed and sealed properly rather than foamed and forgotten, or the door will bind within a year.
Doors and full house work in Caerphilly
A front door is often the first job we do for a Caerphilly customer and a full house of windows is the second. If you are thinking about both, say so at the survey and we will price them together and sequence them so the house is only disrupted once. Whole house replacement is the work we do best and the part of the business the owners most want to grow.
Common questions
How much is a composite front door fitted in Caerphilly?
It depends on size, glass and hardware, so we quote after a free survey rather than guessing over the phone. The written quote covers supply, fitting, removal of the old door and disposal, with nothing added on the day.
How long does the fitting take?
A standard front door swap in Caerphilly takes 4 to 6 hours and is finished the same day. A door with sidelights or a new top light can take a full day.
Do you cover the villages around Caerphilly?
Yes. Bedwas, Trethomas, Machen, Llanbradach, Abertridwr, Senghenydd, Nelson and Ystrad Mynach are all inside our normal working patch, along with the whole of CF83.
What guarantee comes with the door?
A 10 year product guarantee on the door and frame plus a 2 year guarantee on our fitting. We are fully insured and our Checkatrade profile is rated 10 out of 10.
What we typically find on composite doors surveys around here
- ·The friction hinge on a bedroom window has one detent — it either opens fully or slams shut on any breeze.
- ·There is a paint bridge from the internal architrave to the frame that will crack the moment the new unit lifts out.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.
- ·The old timber back door has a live rot pocket at the bottom hinge that reads soft to a screwdriver tip.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The garden gate side of the property gets no direct sun and the frames there look ten years newer than the fronts.
- ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
- ·The georgian bar between the panes has come detached from the top spacer on one unit.
- ·A previous decorator's dust sheet was left inside the frame chamber during a repaint and is still there.
- ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·The letter plate cover has snapped off and the exposed brush strip has flattened over the years.
- ·The friction stays are the wrong hand for the sash — a previous swap fitted left-hand stays on a right-hand window.
- ·The internal glazing bead sits proud of the frame by 1.5mm, so the seal at the top corner has failed first.
- ·The letterplate flap spring has gone slack and the flap now hangs open in a light breeze.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.

- ·The resident has already had one failed installation and wants to know exactly how this one will differ.
- ·The owner is having a kitchen refit next month and wants the patio door in first so the tiler works to a fitted threshold.
- ·The buyer wants the whole job done by one team who own the outcome — not designed in one place and fitted in another.
- ·The owner is done reheating rooms every hour because the frames leak the heat straight back out again.
- ·The homeowner has just re-rendered the front elevation and wants the frames to be the last piece of the picture.
- ·The buyer wants a written commitment on the sealant colour and the trim colour before any deposit changes hands.
How our fitters actually do the work
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
- ·Door thresholds are set with a spirit level along their full length and then re-checked with a straight edge.
- ·The frame reinforcement is chosen for the wind load exposure of the elevation, not the smallest steel that fits.
- ·The client's alarm sensors on the old frames are removed and returned to the client, not binned by default.
- ·The door is closed, locked, and left overnight before final adjustment, so any settlement is captured before sign-off.
- ·The glass has a factory kite mark visible at handover — not scraped off by a lazy cleaner during the fitting hour.
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The screws through the outer frame go into pilot-drilled masonry, not driven with hammer action alone.
- ·The bay assembly is squared with a laser diagonal, not a tape measure and eye.
- ·The internal cill support is packed with hardwood the full depth of the cill, not just at the ends.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- ·The internal make-good uses caulk to the plaster, silicone to the tiles, and neither where paint has to go over.
- ·The letterplate brush strip is trimmed to the exact height of the door thickness so it seals without dragging.
- ·The fitting van is stocked with the specific spare parts likely to be needed on the day — not a return trip on a missing hinge.
- ·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.

Can composite doors handle wind-driven rain off the mountain ridge?+

Fitted in a single day, usually 4–6 hours. Most of the stone-fronted terraces we see in Caerphilly fit our standard schedule with no surprises.
Do you do commercial composite doors for sites near Pontygwindy Industrial Estate?+
Yes. We've worked across Pontygwindy Industrial Estate and Bedwas House Industrial Estate, supplying the same 48mm solid composite slab build we use on residential. Commercial quotes include site access notes and out-of-hours options.
Why replace the whole set rather than one-by-one in a Caerphilly home?+
Because old timber and rotten 90s uPVC front doors that leak heat, jam in winter and fail break-in standards 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 CF83.
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 composite doors
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
A composite slab that catches on the frame has almost always moved at the hinges, and hinges are adjustable in three planes.
Most break-ins through glazed openings exploit the cylinder or the keeps, both of which are upgradeable in an afternoon.
