Composite Front Doors on an Edwardian bay-fronted house in Caerphilly
Families in the leafy Edwardian suburbs and downsizers moving back into the character stock for the layout. That's the mix reaching out for composite doors in Caerphilly on this property type — often as part of a wider refresh, sometimes as a like-for-like fix. A four-panel composite in a heritage colour, matched to a re-set stained-glass fanlight, keeps the original tile porch reading right. We salvage the original toplight where it's intact and mount it above the new frame. Vaulted internal ceilings mean the crew works off a small tower for gable glazing — ground protection sheeting mandatory. Off-street parking makes van access straightforward — we can stage glass in the driveway rather than on the pavement. External cill drips block with paint over the decades — raking them clean stops water sitting on the frame after install. Off-street parking makes van access straightforward — we can stage glass in the driveway rather than on the pavement. Vaulted internal ceilings mean the crew works off a small tower for gable glazing — ground protection sheeting mandatory. Original front cills are usually blue engineering brick — leave them, drill through them for the frame fixings. External cill drips block with paint over the decades — raking them clean stops water sitting on the frame after install. Original 60s sliding aluminium frames cold-bridge — you can feel a two-degree temperature drop within a foot of the glass in winter. Salt air pits cheap aluminium at the fixing points; genuinely marine-grade powder coating resists.

Common edwardian bay-fronts problems we quote composite doors for
- 1Porch tiles cracked around the door frame where the timber has moved.
- 2Stained-glass toplights removed and re-glazed as plain — worth preserving where intact.
- 3The original bay corner posts have almost always been replaced in cheap 90s uPVC and now sag.

Who's asking
Families in the leafy Edwardian suburbs and downsizers moving back into the character stock for the layout.
In Caerphilly specifically that reads as young families upgrading first homes, long-time owners replacing original 90s uPVC. The recurring driver for a composite doors enquiry is: Owners who want the bay preserved as a feature, not flattened, and hardware that reads period.
Planning & permissions
Bay elevations are a strongly protected feature in most Edwardian conservation areas — we usually replicate the original sightlines rather than modernise.
Locally in Caerphilly, Caerphilly County Borough Council covers this area. Market town with the castle as the centrepiece — a mix of stone period stock and modern estates. We check any conservation or Article 4 status against the address before quoting rather than after.
What we typically find on survey
- ·The reinforcement steel inside the top rail of a wide sash has rusted through in one corner.
- ·Original door furniture is 90s brass, tarnished, and no longer matches anything else on the elevation.
- ·The composite front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·The cylinder on the front door still has the builder's key stamp, meaning it has never been changed since handover.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·The window opens fine on a cold morning and binds by 3pm on a hot afternoon — classic thermal-expansion bind.
- ·A cat flap has been cut through the lower panel of the back door, weakening the panel and voiding warranty.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·There is a paint bridge from the internal architrave to the frame that will crack the moment the new unit lifts out.
- ·The old timber back door has a live rot pocket at the bottom hinge that reads soft to a screwdriver tip.
- ·The catch keep for the bathroom window has been packed out with a folded matchbox to make the sash lock.
- ·The letterplate has a hinged internal flap that has snapped off and is currently held in place with masking tape.
- ·A cracked pane has been temporarily patched with clear tape and left for six months.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·The bottom hinge on the front door has torn its top screw fixing free of the frame.
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.
- ·The bathroom pane is patterned glass from the original build, and the pattern is no longer a current stock line.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
- ·The gasket at the vent has perished and pulled away from its channel in two-inch sections.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
- ·The letterbox opening is not draught-proofed at all — a candle held two feet away flickers in a light wind.
- ·The internal reveal architrave has been re-fixed with panel pins that have rusted and stained the paintwork.
- ·The porch-roof lead flashing has been dropping water onto the head of the front door for years.
Why residents are enquiring right now
- ·A recent break-in on the street has moved security up the priority list ahead of aesthetics.
- ·The homeowner is 68 and wants a threshold that will still be usable in ten years without a step.
- ·The resident wants the crew to be locals who won't disappear if a warranty call needs answering in year eight.
- ·The owner is preparing the property for a rental switch and wants glazing to hit HMO fire-escape spec.
- ·The homeowner wants a five-star Checkatrade installer at the door, not a subcontracted crew nobody has vetted.
- ·The resident has already had one failed installation and wants to know exactly how this one will differ.
- ·The resident wants the letterbox to stop being a draught source without giving up daily post.
- ·The resident wants an installer who will honestly say when a repair beats a replacement.
- ·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
- ·The homeowner is fine spending more if the crew is right — the price is the last question, not the first.

- ·The owner wants the property to look ten years newer without needing an extension.

- ·The homeowner has quotes from two national companies and wants a local one to be honest about the same job.
- ·The buyer wants the property to be quieter after 11pm — the street noise is fine, the bass from next door is not.

- ·The resident is moving elderly parents in downstairs and needs the front threshold to be wheelchair-usable.
How we actually fit it
- ·The crew leaves the client with a printed adjustment card so the multipoint keeps can be re-set six months on without a callout.
- ·The crew calls the client at 5pm the day before to confirm arrival window and site access details.
- ·The lock cylinder is measured to sit flush with the escutcheon plate — a proud cylinder is a snap risk.
- ·The reveal is brushed down and vacuumed before any sealant runs, so the bead adheres to substrate, not dust.
- ·The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
- ·The glazing bead is tapped in with a rubber mallet, not a metal claw — the profile marks otherwise.
- ·New frames sit on hardwood packers, not plastic offcuts — plastic creeps under load, timber does not.
- ·The old frame's fixing holes in the brick are filled and made good before the new outer frame beads up to the reveal.
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
- ·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.
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The crew takes the old glass off site in a labelled sack that day, not a skip left on the drive.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·The perimeter foam goes in in two passes so the second lift meets the first without a void in the middle.
- ·The install date is stamped inside the frame chamber for future reference — a decade later a client can still date it.
- ·The frame reinforcement is chosen for the wind load exposure of the elevation, not the smallest steel that fits.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The cylinder key gets a keyring immediately, so it does not sit unnoticed in a jacket pocket for the day.
- ·The old keys are collected and destroyed, not left in a bag on the drive.
