New solid roof conservatories for Blackwood homes
Most of our solid roof conservatories jobs in Blackwood start with the same call: "wanting the space of a conservatory without the temperature swing, the glare and the heating cost that comes with a glass or plastic roof". Around here that usually means a a broad mix where the original frames have given up. We work right across NP12 — Cefn Fforest, Pontllanfraith, Oakdale and the surrounding streets — typically arriving via A4048. Base and dwarf wall checked or built, frames set and levelled, solid roof structure craned or lifted on, then insulated, tiled, boarded and skimmed so the inside reads as a room rather than a conservatory.

Landlords, letting agents and portfolio owners around Blackwood: 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.
The things worth checking before you accept a price
- Documentation for the file: guarantee, insurance and compliance certificates
- Work scheduled inside a void period so rent is not lost
- The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- The perimeter tape between frame and reveal is a compressible foam tape, not a plain butyl strip.
Repeat work for local landlords across multiple properties, with the same specification carried between them

What we typically find on solid roof conservatories surveys around here
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·The transom bar has a live crack in the plastic, opened up by summer expansion cycles.
- ·The glazing spacers between panes carry the visible desiccant snowfall that gives away a blown unit.
- ·Condensation runs down the inside of every north-facing pane between October and March.
- ·The escutcheon on the front door is loose and rotates as the key turns.
- ·The cill end-cap has fallen off and the cill chamber is now a home for insects.
- ·The composite door skin has a UV bloom on the south-facing elevation that no longer matches the colour on the shaded elevation.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·The reinforcement steel inside the top rail of a wide sash has rusted through in one corner.
- ·Handles on the ground-floor windows have been swapped for cheap replacements that no longer match the espag rod.
- ·The composite front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·The trickle vent on the master bedroom has been foil-taped shut for warmth — condensation has doubled since.
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·There is a permanent green algal streak below the sill where water is bypassing the drip groove.
- ·The top hinge on the front door has torn its middle screw out and been left to run on two fixings.

- ·The homeowner wants the composite slab to be paintable without voiding the manufacturer warranty.
- ·The wife wants the noise from the trunk road down; the husband wants the heating bill down; both are on the enquiry.
- ·The buyer is moving in with two dogs and needs a back door that will not degrade with claw scrape.
- ·The homeowner is targeting a specific EPC band ahead of a rental switch and needs the frames to contribute measurably.
- ·The resident wants the sliding door to open with a fingertip after ten years of use, not two hands after two.
- ·The owner has scaffolding booked for a re-render and wants the frames sequenced around the render trades.
- ·The buyer wants an installer who will still exist to honour a guarantee in year eight.

- ·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.
How our fitters actually do the work
- ·The manufacturer's kite mark on the corner of the glass is left in place at handover — proof of spec for the next owner.
- ·The multipoint gearbox is thrown by hand before the frame goes in — a factory fault at that point is a five-minute fix.
- ·The finished elevation is photographed from the pavement and uploaded to the office job file as sign-off record.
- ·The old broken glass is bagged in a labelled sack, not tipped loose into a general skip.
- ·The install date is stamped inside the frame chamber for future reference — a decade later a client can still date it.
- ·The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·The frame square is checked at the diagonals before any glass goes in — a square frame stays square.
- ·Cavity closers get inserted where the old frame's cavity closer has failed — not omitted because it is unseen work.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The letterplate brush strip is trimmed to the exact height of the door thickness so it seals without dragging.
- ·The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- ·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.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The internal cill is scribed to the reveal, not just butted and caulked over the gap.
- ·The lock cylinder is measured to sit flush with the escutcheon plate — a proud cylinder is a snap risk.
FAQs — solid roof conservatories in Blackwood
Do you fit solid roof conservatories across all of Blackwood?+
Yes — we work across every NP12 postcode, from Cefn Fforest through to Pontllanfraith, and out as far as Oakdale. The A4048 gives us clear access with a loaded van, and estate driveways here mean unloading is straightforward.
What guarantee do I get when you fit solid roof conservatories in Blackwood?+
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.
Can solid roof conservatories handle first generation double glazing from the 1980s that has misted across whole elevations?+
Directly, yes — built as a permanent room, with the roof structure rated to the same life as a house extension roof. That matters in Blackwood where first generation double glazing from the 1980s that has misted across whole elevations is the single most common reason people call us.
Why replace the whole set rather than one-by-one in a Blackwood home?+
Because wanting the space of a conservatory without the temperature swing, the glare and the heating cost that comes with a glass or plastic roof 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 NP12.
Will solid roof conservatories suit the older a broad mix common around Blackwood?+
A solid roof suits the wetter and windier South Wales climate far better than glass, and it keeps the room warm on valley floors that hold cold air. We've installed dozens in Cefn Fforest and Pontllanfraith alone.
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.

Faults we fix before recommending solid roof conservatories
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.
