Owners of older and character property around Caerphilly: what changes
This page is for older stock where the replacement has to look right as well as perform. Sightlines, reveal depth and the way a frame sits back from the brick face are the difference between a sympathetic job and an obvious one.
What we build into the quote for you
- Slim sightlines so the glass area is not visibly reduced
- Advice on conservation area and planning constraints before ordering
- The lock cylinder is measured for internal and external protrusion — a cylinder that stands proud is a snap risk.
- The perimeter foam goes in in two passes so the second lift meets the first without a void in the middle.

What we typically find on conservatory roof replacement surveys around here
- ·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
- ·The manufacturer's kite mark on the corner of the glass is late-90s vintage, which explains the thermal performance.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The friction hinge on a bedroom window has one detent — it either opens fully or slams shut on any breeze.
- ·A previous fitter left the transport wedges in the frame corners and the internal seal never fully reset.
- ·The old aluminium sliding door has a cracked head roller that pulls the door out of parallel with the frame.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.

- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·Original security bolts on the ground floor sashes are seized in place and no longer key-lockable.
- ·The internal glazing bead across the top of the bay lifts out completely with fingernail pressure.

How our fitters actually do the work
- ·The crew leaves the client with a printed adjustment card so the multipoint keeps can be re-set six months on without a callout.
- ·Any dropped hinges on the existing door are noted before the swap so the new frame is set for the correct drop.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
- ·The reveal is brushed down and vacuumed before any sealant runs, so the bead adheres to substrate, not dust.
- ·The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
- ·The dustsheet inside the room is a heavy canvas taped to the skirting, not a light plastic left loose.
- ·The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·We de-glaze into a padded rack, not straight into the skip — the intact panes go to a glazier for reuse.
- ·The frame drainage caps face outward and are set proud enough that they don't clog with a season of rainwater.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·The internal make-good uses caulk to the plaster, silicone to the tiles, and neither where paint has to go over.
- ·The composite slab is not trimmed on site — if it doesn't fit, a new slab is ordered rather than reduced.
- ·The bay-corner post gets a structural bracket into masonry, not a token fixing into the outer frame.
- ·The window boards are pre-treated on the underside with a moisture seal before setting in place.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
FAQs — conservatory roof replacement in Caerphilly
Can conservatory roof replacement handle wind-driven rain off the mountain ridge?+
Directly, yes — the tile and insulation system carries a 25 year weathering expectation and the room stays usable in january and july. That matters in Caerphilly where wind-driven rain off the mountain ridge is the single most common reason people call us.
Will conservatory roof replacement suit the older stone-fronted terraces common around Caerphilly?+
South Wales rainfall is what kills polycarbonate roofs here, and a warm roof stops both the noise and the heat loss in one job. We've installed dozens in Bedwas and Trethomas alone.
Why replace the whole set rather than one-by-one in a Caerphilly home?+
Because a conservatory that is unusable because it freezes in winter, bakes in summer and drums so loudly in rain that you cannot hear the television 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.
How do you reach jobs in Caerphilly from your base?+
Easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass — typically a short run via A468.
Do you fit conservatory roof replacement across all of Caerphilly?+
Yes — we work across every CF83 postcode, from Bedwas through to Trethomas, and out as far as Machen. Easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass.
Will modern frames look wrong on an older house?+
They can, if the profile is chosen badly. Flush sash sits back into the reveal and keeps the sightline slim, which is why we specify it on older elevations rather than standard chamfered casements.
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.

Faults we fix before recommending conservatory roof replacement
Fog between the panes means the sealed unit has failed — the glass can usually be swapped without touching the frame.
A draught is usually a compression problem — gasket, hinge or seal — long before it's a reason to replace the window.
Which face the water sits on tells you everything: inside is ventilation, between the panes is a failed unit, outside is normal physics.
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
