Exposure to prevailing weather
Crumlin's valley alignment funnels south-westerlies straight against front elevations. We spec enhanced weathering — reinforced gaskets, appropriate glazing spec — on exposed installs as standard.

Serving Crumlin
Why Crumlin homeowners work with us.
Response time. Crumlin surveys are usually offered within 4–6 working days. Fitting slots within 5–7 weeks.
Crumlin's terraces climb the Ebbw valley in steep rows above the old viaduct site. Access is tight, openings are rarely standard, and the exposure to prevailing westerlies is real — which is exactly why local specification matters more than a national quote.
We're twelve minutes up the Sirhowy from Crumlin. That proximity means realistic survey windows, no travel-day surcharges, and a team that knows the streets before they arrive.
Property types we install into
- Steep valley terracesThe classic Crumlin terrace — narrow-fronted, three storeys, non-standard openings and original stone reveals.
- Post-war council stock1950s semis and short terraces on estates like Woodfieldside.
- Hafodyrynys detachedLarger detached properties on the ridge above the valley — often specifying aluminium.

What Crumlin throws at us
Crumlin properties throw specific challenges — here's what we assess at survey.
Non-standard openings
Almost no Crumlin terrace has standard-sized openings. Our in-house manufacture handles the awkward sizes without inflated bespoke premiums.
Access and parking
Terraced streets in Crumlin are narrow and often on gradient. We plan loading and delivery around this so neighbours aren't blocked.
Stone reveal maintenance
Original stone reveals can hide soft mortar joints. We inspect at survey — if a reveal needs rebuilding, we tell you before you sign, not after we're on-site.

Crumlin FAQ
Everything Crumlin customers ask before booking.
Do you install in Crumlin and Hafodyrynys?
Yes — both are within our core area, twelve minutes from our workshop.
How quickly can you survey a Crumlin property?
Usually within 4–6 working days. We batch Crumlin visits with other Sirhowy jobs.
Can you handle non-standard opening sizes without a premium?
Yes — we manufacture our own uPVC in Pontllanfraith, so bespoke sizes don't add cost the way outsourced-bought stock does.
What's a typical Crumlin composite door cost?
From around £1,395 supplied and fitted, depending on colour, glass and hardware spec.
Do you handle stone reveal repairs?
Minor making-good yes. If a reveal needs structural rebuilding we'll advise on a mason before we quote — we don't mask problems.

Yes — Smart and Aluk systems. Popular on Hafodyrynys detached properties.
What guarantee do I get?
10-year product guarantee plus IBG-backed workmanship cover.
Do you handle upper-floor terrace installs safely?
