Composite doors fitted across Nelson & CF46
If you're looking at composite doors for a home in Nelson, you're probably dealing with fully exposed elevations on high ground with nothing to break the wind or period stone cottages where frame style has to suit the building — both common in the village terraces around the old pond and square, stone cottages toward Llanfabon, and scattered detached properties on the higher ground with open exposure on three sides you find across CF46. We've fitted hundreds of sets across Trelewis, Treharris and Llancaiach, all signed off under Caerphilly County Borough Council building standards. The 48mm slab clears most South Wales brick reveals without needing a packer; sidelights match Edwardian bay layouts.

Owners of older and character property
Who this page is for: owners of older and character property in Nelson
On older houses the opening is never square and the reveal is never standard. This page covers how we survey and pack those openings rather than forcing a stock size into them.
What this buyer actually needs from us
- Slim sightlines so the glass area is not visibly reduced
- Heritage colours and traditional hardware rather than stock white and chrome
- The cylinder key gets a keyring immediately, so it does not sit unnoticed in a jacket pocket for the day.
- The composite slab is not trimmed on site — if it doesn't fit, a new slab is ordered rather than reduced.

- ·The old timber sub-cill under a uPVC swap is boron-treatable but only if we lift the frame off it cleanly.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·The kitchen window has a defrost line across the low-e coating — argon gas long gone.

How our fitters actually do the work
- ·The old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The old keys are collected and destroyed, not left in a bag on the drive.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- ·The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
- ·The finished elevation is photographed from the pavement and uploaded to the office job file as sign-off record.
- ·The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- ·The frame is plumbed on two axes before the first fixing goes in — not one axis and then trusted.
- ·Any dropped hinges on the existing door are noted before the swap so the new frame is set for the correct drop.
- ·The frame perimeter sealant is a low-modulus polymer where the substrate is going to move — plain silicone otherwise.
- ·The threshold sealant runs the full width with a single tool pass, not stitched together in inches.
- ·The frame reinforcement is chosen for the wind load exposure of the elevation, not the smallest steel that fits.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
FAQs — composite doors in Nelson
Will composite doors suit the older village terraces around the old pond and square common around Nelson?+
The 48mm slab clears most South Wales brick reveals without needing a packer; sidelights match Edwardian bay layouts. We've installed dozens in Trelewis and Treharris alone.
Why replace the whole set rather than one-by-one in a Nelson 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 CF46.
How do you reach jobs in Nelson from your base?+
A short hop off the A470 at Nelson, and we allow extra time for the narrow lanes out toward Llanfabon — typically a short run via A472.
What colours and finishes are available for composite doors?+
Solidor / Rockdoor style ranges; anthracite, navy, racing green, chartwell, black; brass, chrome or matt black hardware. We bring physical samples to the quote so you can see them against your village terraces around the old pond and square in real light.
Can composite doors handle fully exposed elevations on high ground with nothing to break the wind?+
Directly, yes — grp skins don't warp, fade only slowly under direct uv, and resist coastal salt better than aluminium-skin doors. That matters in Nelson where fully exposed elevations on high ground with nothing to break the wind is the single most common reason people call us.
Can original glazing bar patterns be matched?+
In most cases, using astragal bars externally or bars within the sealed unit. We will show you both at survey because they look noticeably different from the pavement.
Do I need permission to replace windows on a character property?+
Usually not on an unlisted house outside a conservation area. Inside one, or where an article 4 direction applies, the rules are stricter and we will check with the council before you order.

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.
