New full-house replacement for Newport homes
Most of our full-house replacement jobs in Newport start with the same call: "the false economy of replacing one tired window at a time while the others keep failing". Around here that usually means a long Victorian and Edwardian bay fronted terraces through Maindee and Stow Hill where the original frames have given up. We work right across NP19 and NP20 and NP10 — Maindee, Rogerstone, Allt-yr-yn and the surrounding streets — typically arriving via M4 J24 to J28. Front-to-back schedule: front elevation first, sides, then rear; one team on site each day; rubbish cleared nightly.

Owners of older and character property
Why full-house replacement look different to owners of older and character property
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.
The things worth checking before you accept a price
- Slim sightlines so the glass area is not visibly reduced
- Astragal or bar options that match the original glazing pattern
- The internal beads are numbered on removal so they return to the same corner they came from.
- The internal skirting is protected with a strip of packing tape across the top edge before any tool touches it.
Ten year product guarantee on heritage profiles exactly as on standard ranges
What we typically find on full-house replacement surveys around here
- ·The internal glazing bead sits proud of the frame by 1.5mm, so the seal at the top corner has failed first.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·The mid-rail on the composite door is bowed outward at the middle by 2mm — a slab-warp symptom.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·A previous fitter drilled through the outer frame chamber for the trickle vent — never fully sealed the drilling.
- ·The multipoint lock still throws but the internal handle has 40° of dead travel before engaging.
- ·The bay-corner post has bowed by about 4mm across two metres — visible only if you sight along it.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·The bay corner post has never had its structural bracket — a common corner-cutting shortcut a decade ago.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The composite slab has swelled by 2mm on the hinge stile from years of morning-sun exposure.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
Why residents are booking full-house replacement right now
- ·The buyer has just moved in and is fixing everything the vendor's homebuyer report flagged, in priority order.
- ·The buyer wants no upsell scripts — a survey, a spec, a figure, and space to think.
- ·The resident is expecting an elderly parent to move in and needs a door that opens without a shove.
- ·The buyer wants a genuine Which? Trusted Trader install, not a subcontracted crew running the badge.
- ·The buyer wants the whole ground floor to feel more connected to the garden without losing the wall.
- ·The homeowner is planning a loft conversion next year and wants the windows sorted before scaffold cost is priced.
- ·The owner wants the crew to talk to the neighbour before scaffold goes up on a shared party wall.
- ·The owner just remortgaged and wants the money to be visible on the elevation for the next valuation.
- ·The resident has a shift-worker sleeping in the day and needs the bedroom to be a genuine acoustic step change.
- ·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 wants the sound of the sea audible but the wind noise gone.
- ·The resident wants the patio door to slide with one finger — not the two-handed heave the current one takes.
- ·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 electric car on the drive and wants the front to say the whole property has been kept up.
- ·The homeowner wants the composite slab to be paintable without voiding the manufacturer warranty.
- ·The buyer wants the heating bill visibly lower before next winter, not a marginal improvement they have to guess at.
How our fitters actually do the work
- ·The client is left with the manufacturer's paperwork in a labelled envelope, not a folded receipt tucked inside a drawer.
- ·New frames sit on hardwood packers, not plastic offcuts — plastic creeps under load, timber does not.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·The door slab gets a full inspection before hanging — dents, delamination, edge integrity, all noted before fixings go through.
- ·The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The internal cill is scribed to the reveal, not just butted and caulked over the gap.
- ·The internal make-good uses caulk to the plaster, silicone to the tiles, and neither where paint has to go over.
- ·Fixings are set at the manufacturer's spacing, not evenly spaced by eye — the corner loads matter.
- ·The perimeter foam goes in in two passes so the second lift meets the first without a void in the middle.
- ·The client's Wi-Fi router near the door is checked for a signal drop after the composite slab is fitted — a rare case, but worth confirming.
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
- ·The frame is protected with a low-tack tape at any point a tool might scrape it during the fitting hour.
- ·The bay-corner post is set with a laser level across both faces before the outer frames are trimmed to fit.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
FAQs — full-house replacement in Newport
Do you fit full-house replacement across all of Newport?+
Yes — we work across every NP19 and NP20 and NP10 postcode, from Maindee through to Rogerstone, and out as far as Allt-yr-yn. M4 J28 puts most of Newport inside half an hour of our Caerphilly base, so survey and fit dates rarely slip.
Will full-house replacement suit the older long Victorian and Edwardian bay fronted terraces through Maindee and Stow Hill common around Newport?+
We sequence the install so terraced neighbours and parked cars aren't blocked all week — a real concern on Welsh valley streets. We've installed dozens in Maindee and Rogerstone alone.
Why replace the whole set rather than one-by-one in a Newport home?+
Because the false economy of replacing one tired window at a time while the others keep failing 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 NP19.
Can full-house replacement handle Severn estuary wind and salt reaching NP19 and NP10 addresses?+
Directly, yes — whole property reset to a-rated thermal performance for a 20-year horizon. That matters in Newport where Severn estuary wind and salt reaching NP19 and NP10 addresses is the single most common reason people call us.
What colours and finishes are available for full-house replacement?+
one consistent foil/RAL across every elevation; front door, back door and patio doors as a coordinated set. We bring physical samples to the quote so you can see them against your long Victorian and Edwardian bay fronted terraces through Maindee and Stow Hill in real light.
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.
Do I need permission to replace windows on a character property?+
Usually not on an unlisted house outside a conservation area. Inside one, or where an article 4 direction applies, the rules are stricter and we will check with the council before you order.
Solve Severn estuary wind and salt reaching NP19 and NP10 addresses for good
Our full-house replacement use argon-filled units to fix the root cause — not patch it.

Faults we fix before recommending full-house replacement
A draught is usually a compression problem — gasket, hinge or seal — long before it's a reason to replace the window.
Rot in the bottom rail is repairable; rot that has reached the joints and the cill usually isn't worth chasing.
Yellowing is cosmetic and treatable; splits at the welded corners are structural and aren't.
