New build, extension and self build projects
Why solid roof conservatories look different to new build, extension and self build projects
Written for extensions, garden rooms and self builds where the opening is being formed rather than reused. The critical items are the structural opening sizes, the weatherproofing detail and when we can get on site relative to the brickwork.
The things worth checking before you accept a price
- Structural opening sizes agreed and issued to the builder in writing
- Cill, lintel and cavity closer details resolved before frames are ordered
- The site tidy happens twice per day, not once at the end, so brick dust doesn't track through the house.
- The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
Extension and garden room glazing completed to the builder's programme, with sizes issued before brickwork started

What we typically find on solid roof conservatories surveys around here
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·Original door furniture is 90s brass, tarnished, and no longer matches anything else on the elevation.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·The multipoint gearbox on the front door still throws, but the hooks miss the keeps by 2mm on the middle throw.
- ·The glazing spacers between panes carry the visible desiccant snowfall that gives away a blown unit.
- ·The bay-corner post has bowed by about 4mm across two metres — visible only if you sight along it.
- ·The bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·The friction stays are the wrong hand for the sash — a previous swap fitted left-hand stays on a right-hand window.
- ·The cill drainage caps on a north-facing elevation are frozen in place with layered moss.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
- ·The top hinge on the front door has torn its middle screw out and been left to run on two fixings.
- ·The porch-roof lead flashing has been dropping water onto the head of the front door for years.
- ·The outer frame has moved fractionally over the years, dropping the bottom hinge screw pattern out of line.
- ·The manufacturer's kite mark on the corner of the glass is late-90s vintage, which explains the thermal performance.
- ·The front door has been painted three times without stripping — the paint film is now stopping the door closing at the top.
Why residents are booking solid roof conservatories right now
- ·The owner wants the front door hardware to match a specific interior palette — brass, matt black, or brushed nickel.
- ·The buyer wants no upsell scripts — a survey, a spec, a figure, and space to think.
- ·The homeowner wants the composite slab to be paintable without voiding the manufacturer warranty.
- ·There is a puppy in training and the sliding door onto the garden has to work with a paw against the glass.
- ·The resident works from home and wants the neighbour's dog to stop being the loudest thing on every call.
- ·The resident cycles to work and wants a bike-in-porch design that a survey needs to plan around.
- ·The buyer wants the front door delivered pre-hung and pre-glazed on the same date as the frames.
- ·The resident wants an installer who will honestly say when a repair beats a replacement.
- ·The owner has an electric car on the drive and wants the front to say the whole property has been kept up.
- ·The owner has watched the bay corner posts sag for a decade and now wants them straight and structural.
- ·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
- ·The resident has a shift-worker sleeping in the day and needs the bedroom to be a genuine acoustic step change.
- ·The buyer wants a composite door slab that a courier's boot cannot dent when a delivery is fumbled.
- ·The resident has been quoted for solar and does not want the roof work to happen before the windows do.
- ·The owner is having a kitchen refit next month and wants the patio door in first so the tiler works to a fitted threshold.
- ·The owner is preparing the property for a rental switch and wants glazing to hit HMO fire-escape spec.
How our fitters actually do the work
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
- ·The mitre joins on any Georgian bar are picked to face the corner that is least visible from indoors.
- ·The window boards are pre-treated on the underside with a moisture seal before setting in place.
- ·The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- ·The frame perimeter sealant is a low-modulus polymer where the substrate is going to move — plain silicone otherwise.
- ·The old frame comes out in one piece where possible so the reveal detail is not chased through with a demolition bar.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The frame square is checked at the diagonals before any glass goes in — a square frame stays square.
- ·The glazing bead is tapped in with a rubber mallet, not a metal claw — the profile marks otherwise.
- ·The trickle vent chamber inside the frame is proven clear with a torch before the outer cap goes on.
- ·The old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The glass has a factory kite mark visible at handover — not scraped off by a lazy cleaner during the fitting hour.
- ·The head of the frame is packed dry before the sides are fixed, so the frame does not distort during installation.
- ·The old frame's fixing holes in the brick are filled and made good before the new outer frame beads up to the reveal.

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.
