New build, extension and self build projects
Why triple glazing 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
- Delivery timed to the build programme rather than to our diary
- Door thresholds are set with a spirit level along their full length and then re-checked with a straight edge.
- The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
Performance figures supplied in writing for building control and SAP calculations
What we typically find on triple glazing surveys around here
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·The composite front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·The old aluminium sliding door has a cracked head roller that pulls the door out of parallel with the frame.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
- ·The escutcheon plate on the back door hides a botched cylinder swap where the follower is worn.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
- ·The letter plate cover has snapped off and the exposed brush strip has flattened over the years.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·A previous owner has fitted a chain to the front door on top of the multipoint — a sign they never trusted the lock.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The escutcheon on the front door is loose and rotates as the key turns.
- ·The composite door slab has a hairline crack along the letterplate cut-out from a delivery boot.
- ·The friction hinge on one window sticks at 45° open and needs the palm of a hand to nudge past.
Why residents are booking triple glazing right now
- ·The homeowner is preparing to work from home permanently and wants the office quieter than the living room used to be.
- ·The resident wants the crew to be locals who won't disappear if a warranty call needs answering in year eight.
- ·The owner wants the front door hardware to match a specific interior palette — brass, matt black, or brushed nickel.
- ·The buyer wants the heating bill visibly lower before next winter, not a marginal improvement they have to guess at.
- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·The resident wants the ground-floor windows to be genuinely secure — laminated inner pane, PAS24 hardware, real not marketed.
- ·The homeowner wants the back door to be a family door — kids in and out, and no one having to slam it to lock.
- ·The buyer has just moved in and is fixing everything the vendor's homebuyer report flagged, in priority order.
- ·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 owner has watched a neighbour's crew leave debris behind and wants a written cleanup expectation on the quote.
- ·The homeowner wants the property EPC to move up a band ahead of a remortgage in six months.
- ·The buyer wants the whole job done by one team who own the outcome — not designed in one place and fitted in another.
- ·The homeowner wants matt black hardware because everything inside the house is matt black — no chrome to argue with.
- ·The homeowner is fine spending more if the crew is right — the price is the last question, not the first.
- ·The homeowner is planning a garden studio and wants the patio doors to bookend the view when it's finished.
- ·The resident wants the sliding door to open with a fingertip after ten years of use, not two hands after two.
How our fitters actually do the work
- ·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 door slab gets a full inspection before hanging — dents, delamination, edge integrity, all noted before fixings go through.
- ·The internal beads are numbered on removal so they return to the same corner they came from.
- ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The client is left with the manufacturer's paperwork in a labelled envelope, not a folded receipt tucked inside a drawer.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The frame is protected with a low-tack tape at any point a tool might scrape it during the fitting hour.
- ·Foam gets a wet finger dressed into the internal reveal, not a dry-cut strip that pulls back later.
- ·The internal cill support is packed with hardwood the full depth of the cill, not just at the ends.
- ·The trim between the frame and the plaster line goes on last, after the sealant has set and been proven leak-tight.
- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
- ·Door thresholds are set with a spirit level along their full length and then re-checked with a straight edge.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The install date is stamped inside the frame chamber for future reference — a decade later a client can still date it.
FAQs — triple glazing in Ystrad Mynach
How long does a triple glazing install take in a Ystrad Mynach property?+
1 day per elevation with the heavier units, or 2–3 for a full house. Most of the railway era terraces near the station we see in Ystrad Mynach fit our standard schedule with no surprises.
What guarantee do I get when you fit triple glazing in Ystrad Mynach?+
10-year sealed unit guarantee, 10-year frame, 2-year fitting. We're insured to work right across Caerphilly County Borough Council's area, and you have one named contact from quote to snag.
Why replace the whole set rather than one-by-one in a Ystrad Mynach home?+
Because traffic noise from the A470 or A469 that double glazing only partly muffles, and cold radiating off the glass at night 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 CF82.
How do you reach jobs in Ystrad Mynach from your base?+
Ten minutes north of Caerphilly on the A469, so we can survey in the morning and quote the same afternoon — typically a short run via A472.
Do you do commercial triple glazing for sites near Tredomen Business Park?+
Yes. We've worked across Tredomen Business Park and the Penallta industrial units, supplying the same 44mm triple-glazed sealed units build we use on residential. Commercial quotes include site access notes and out-of-hours options.
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.

Faults we fix before recommending triple glazing
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.
Asymmetric glass thickness and a good frame seal cut traffic noise; simply adding a third identical pane often doesn't.
Most of the heat leaves through the roof and the frames, so that's where the money should go first.
