Crumlin Windows & doors · Crumlin NP11 # Windows & Doors, Fitted Across Crumlin & Hafodyrynys Steep valley terraces, exposed elevations, non-standard openings — we've installed across Crumlin for years and know what these houses need. [Request free Crumlin survey](/contact) [01495 825934](tel:+441495825934) Free survey in Crumlin, usually within the week · 10-year guarantee NP11 12 min from workshop Sirhowy & Ebbw Valleys - ASSURE registered installer - MTC-certified fitters - VEKA · Smart · Aluk approved - 10-year guarantee + IBG - Family business since 1997 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 terraces The classic Crumlin terrace — narrow-fronted, three storeys, non-standard openings and original stone reveals. - Post-war council stock 1950s semis and short terraces on estates like Woodfieldside. - Hafodyrynys detached Larger detached properties on the ridge above the valley — often specifying aluminium. Common Crumlin service needs - Full re-glaze programmes Whole-house replacements where original 1990s uPVC has gone. - Composite doors Solid, secure front doors in colours that stand out against stone terraces. - Bespoke sizes Very little of Crumlin fits standard window sizes — we manufacture to survey.

Crumlin homeowners choose us because we understand valley properties — not because we're the cheapest phone-quote. ### Valley-specialist install team Our fitters install in Crumlin, Newbridge, Abercarn and Abertillery every week. Nothing about a Sirhowy or Ebbw terrace surprises us. ### Bespoke manufacture We make our own uPVC frames, so non-standard Crumlin openings don't add weeks to your job or cost more than standard sizes. ### ASSURE registered Every install compliance-certificated by the ASSURE scheme. ### 10-year guarantee + IBG Product and workmanship covered for a decade, backed by Insurance-Backed Guarantee. What Crumlin throws at us ## Crumlin properties throw specific challenges — here's what we assess at survey. ### 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. ### 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. Our process ## Five steps from Crumlin enquiry to guaranteed install. 1. STEP 01 ### Enquiry & call-back One quick call to understand what you're after — no scripted pitch, no pressure. 2. STEP 02 ### Free measured survey We visit, measure to the millimetre, and check reveals, lintels and access — usually within the week. 3. STEP 03 ### Fixed written quote Line-by-line, no rounded 'today only' discounts. You take it away and think about it. 4. STEP 04 ### In-house manufacture Bespoke frames and doors made in our Pontllanfraith workshop — no distant factory lead-times. 5. STEP 05 ### Guaranteed install Our own MTC-certified fitters, compliance certificate via ASSURE, 10-year IBG-backed guarantee. Crumlin FAQ ## Everything Crumlin customers ask before booking.
