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.
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
- ·The internal reveal plaster is spalling under the cill where condensation has run for years.
- ·The letterplate is a straight through-plate with no anti-snap flap — visible from outside in the hallway.
- ·The cill drainage caps on a north-facing elevation are frozen in place with layered moss.

- ·The resident wants the letterbox to stop being a draught source without giving up daily post.

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.
- ·The manufacturer's serial-number label on the new frame is peeled off, not left to yellow on the glass for years.
- ·The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- ·We de-glaze into a padded rack, not straight into the skip — the intact panes go to a glazier for reuse.
- ·The keeps for the multipoint are set with a strike plate template, not marked by eye against the closed door.
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
Landlords, letting agents and portfolio owners
Landlords, letting agents and portfolio owners around Caerphilly: what changes
This page is aimed at rental stock rather than owner occupied homes. The priorities are different: void periods, compliance, hardware that survives tenants, and a spend that can be justified against rent and EPC banding.
What matters most on this kind of job
- One invoice per property with each opening listed for the accounts
- Work scheduled inside a void period so rent is not lost
- The frame reinforcement steel is confirmed by knock-test before selecting the fixing pattern.
- The head of the frame is packed dry before the sides are fixed, so the frame does not distort during installation.
Repeat work for local landlords across multiple properties, with the same specification carried between them

Questions we get on Edwardian bay-fronts jobs like this
Is it worth upgrading the whole elevation rather than one opening?+
On a edwardian bay-fronts it often is, because the frames were fitted at the same time and tend to fail together. Owners who want the bay preserved as a feature, not flattened, and hardware that reads period. We price both options so you can compare them properly.
Do you handle the old frames and glass?+
Removal, disposal and recycling are all in the quoted figure. Sealed units go to a glass processor, uPVC to a profile recycler, and the skip or van load never sits on a Caerphilly street overnight.
How much disruption should we expect inside?+
Dust sheets down, one room at a time, and the old units carried out through the nearest external door rather than through the house where we can. On a edwardian bay-fronts the internal plaster reveal is the sensitive part, so we cut the old frame out rather than lever it. Fitted in a single day, usually 4–6 hours.
Do you fit composite doors on edwardian bay-fronts around Caerphilly?+
Regularly. Bedwas, CF83 is where most of this work lands, and we also cover Cardiff, Newport, Pontypridd. Easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass.
Can the work be done between tenancies?+
That is how most of our rental work runs. Give us the void dates at enquiry and we will confirm before you accept whether the programme fits inside them.
Will new windows move the EPC band?+
Replacing failed or single glazed units with A rated sealed units improves the fabric score. How far the band moves depends on heating, insulation and the rest of the assessment, so we will not promise a specific letter.

Summary — composite doors on a Edwardian bay-fronted house in Caerphilly
Edwardian bay-fronted house jobs in Caerphilly get a named contact from survey to snag. 10-year product guarantee with a 2-year fitting guarantee on top sits behind it. Estate roads are wide and van-friendly — we can leave the truck in one spot for the whole day without moving. Bay ceiling drops usually have a beam boxed in above — we route silicone around the boxing edge rather than through it. Around Caerphilly that usually means wind-driven rain off the mountain ridge on stone-fronted terraces, post-war semis around the castle and newer estates out toward Bedwas, with Bedwas and Trethomas the streets we are on most. Front door threshold sits on a York stone step in most cases — level it back to the tile line before the frame lands. Non-square reveals mean every frame is bespoke-scribed — templates rather than standard sizes. Timber-frame construction means fixings go into studs; we probe before drilling to locate them. Party wall proximity means neighbours hear the removal — we knock ahead and time the noisy hour to mid-morning.
