New conservatories for Caerphilly homes
Most of our conservatories jobs in Caerphilly start with the same call: "old polycarbonate-roof conservatories that overheat in summer and freeze in winter — a solid warm roof fixes both". Around here that usually means a stone-fronted terraces where the original frames have given up. We work right across CF83 — Bedwas, Trethomas, Machen and the surrounding streets — typically arriving via A468. Base surveyed and steel-reinforced footings poured where needed, dwarf wall built, frames and roof craned or lifted into place, doors and glazing sealed to the existing house.

New build, extension and self build projects
New build, extension and self build projects around Caerphilly: what changes
This page is for work on a new structure rather than a replacement in an existing opening. Tolerances, cill details and the order of trades matter far more than they do on a straight swap.
What we build into the quote for you
- Coordination with the plasterer so reveals are finished cleanly
- Building regulations compliant ventilation and safety glazing specified up front
- The van carries a set of dust extraction attachments and uses them on any grinder work in occupied rooms.
- The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
Performance figures supplied in writing for building control and SAP calculations
- Wind-driven rain off the mountain ridgeOur conservatories address this with uPVC or aluminium frame system.
- Noise from the A469 corridorOur conservatories address this with uPVC or aluminium frame system.
- Tired 1990s-era double glazing failing at the sealsOur conservatories address this with uPVC or aluminium frame system.
What we typically find on conservatories surveys around here
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·The internal glazing bead across the top of the bay lifts out completely with fingernail pressure.
- ·The garden gate side of the property gets no direct sun and the frames there look ten years newer than the fronts.
- ·Every kitchen window handle has been replaced twice in ten years — a sign the espag is going, not just the handle.
- ·There is a live crack running from the top corner of a bay-window pane where the frame has been out of square since installation.
- ·Condensation runs down the inside of every north-facing pane between October and March.
- ·The manufacturer's kite mark on the corner of the glass is late-90s vintage, which explains the thermal performance.
- ·The bottom hinge on the front door has torn its top screw fixing free of the frame.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·The top vent has been kept permanently closed with a wooden shim wedged inside the frame.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
- ·The bay corner post has never had its structural bracket — a common corner-cutting shortcut a decade ago.
- ·The reveal internally has been skimmed over the old plaster edge, hiding a 6mm gap behind the architrave.
- ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
Why residents are booking conservatories right now
- ·The buyer wants a genuine step-up in security, not a marketing claim — PAS24 tested, not PAS24 marketed.
- ·The owner is done with the biannual repaint of the timber back door and wants a paint-free equivalent.
- ·The resident wants the letterbox to stop being a draught source without giving up daily post.
- ·The homeowner wants a five-star Checkatrade installer at the door, not a subcontracted crew nobody has vetted.
- ·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
- ·The resident wants the kitchen brighter in the mornings without losing the privacy from next door's back garden.
- ·The buyer wants the frames branded with the manufacturer's paperwork stapled to the frame chamber for the next owner.
- ·The homeowner wants a warranty they can pass on to the next owner without a fee or a form.
- ·The buyer is furnishing the property for short-term let and wants a five-year cosmetic warranty on the door slab.
- ·The owner has an ageing parent visiting for extended stays and wants the guest bedroom warmer than it currently is.
- ·The homeowner is preparing to work from home permanently and wants the office quieter than the living room used to be.
- ·The buyer has just moved in and is fixing everything the vendor's homebuyer report flagged, in priority order.
- ·The owner is preparing the elevation for a specific street-photo listing and wants the finish to be photographable in raking morning light.
- ·The resident is on a listed street and wants a front door that will pass Article 4 first time.
- ·The resident is fitting a home cinema in the front room and needs the windows to be a full acoustic upgrade, not a nominal one.
- ·The buyer wants the property to look owned rather than tenanted — the front door tells that story first.
How our fitters actually do the work
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The lock cylinder is measured for internal and external protrusion — a cylinder that stands proud is a snap risk.
- ·The keys are handed to the client only after the lock has been thrown four times in and out from both sides.
- ·The frame is protected with a low-tack tape at any point a tool might scrape it during the fitting hour.
- ·The threshold sealant runs the full width with a single tool pass, not stitched together in inches.
- ·The bathroom obscure glass pattern is confirmed with a physical sample against the existing pane, not chosen from a brochure image.
- ·Every silicone bead is tooled with the correct radius spatula, not smoothed with a wet finger only.
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The gasket is dressed into every corner with a specific gasket tool, not a screwdriver, so the corner stays sharp.
- ·The trim between the frame and the plaster line goes on last, after the sealant has set and been proven leak-tight.
- ·The wall around the frame is Hoovered before the client sees the room again — brick dust ages a first impression.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
- ·The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·The old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
FAQs — conservatories in Caerphilly
Do you fit conservatories 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.
What guarantee do I get when you fit conservatories in Caerphilly?+
10-year product, 2-year fitting, structural warranty on the base. We're insured to work right across Caerphilly County Borough Council's area, and you have one named contact from quote to snag.
Will conservatories suit the older stone-fronted terraces common around Caerphilly?+
Warm-roof upgrades suit the wetter South Wales climate — they hold heat and stop the roof drumming during valley downpours. We've installed dozens in Bedwas and Trethomas alone.
Do you do commercial conservatories for sites near Pontygwindy Industrial Estate?+
Yes. We've worked across Pontygwindy Industrial Estate and Bedwas House Industrial Estate, supplying the same uPVC or aluminium frame system build we use on residential. Commercial quotes include site access notes and out-of-hours options.
Can conservatories handle wind-driven rain off the mountain ridge?+
Directly, yes — 20-year frame life with the modern warm-roof option keeping the room usable year-round. That matters in Caerphilly where wind-driven rain off the mountain ridge is the single most common reason people call us.
Do you work from architect's drawings?+
Yes. Send the elevations and we will return structural opening sizes, cill details and the glazing specification in writing so the openings are formed correctly.
When should glazing be ordered on a new build?+
As soon as the openings are confirmed. Manufacture takes weeks rather than days, and ordering late is the most common reason glazing holds up a build programme.
Solve wind-driven rain off the mountain ridge for good
Our conservatories use self-cleaning glass roof or solid warm roof to fix the root cause — not patch it.
