We work in Caerphilly weekly: it's one of our most regular travel areas because the trip is short enough to fit around Pontypridd work without disrupting the day. ### Caerphilly Property Types We Know Caerphilly's housing splits between the town centre's mix of Victorian and Edwardian stone-fronted terraces (similar in build to what we know intimately in Pontypridd), post-war semis spreading across Bedwas, Trethomas, Llanbradach and Energlyn, and newer estates around Lansbury Park, Pontygwindy and the Caerphilly fringes. The valleys above — Senghenydd, Abertridwr, Aber — carry the older stone terraced miners' housing. ### Common Briefs In Caerphilly Most Caerphilly briefs we price are kitchen-diner rear extensions on the post-war semis, full renovations on the Victorian town-centre terraces, and silicone render systems over tired pebbledash on the 60s–80s estates. The valley villages (Senghenydd, Abertridwr) bring more solid-stone repair and lime-pointing work — same skill set we use on Pontypridd's older stock. ### Driving Time To Caerphilly 20–25 minutes from Pontypridd to most of Caerphilly. The fastest route is A470 to Nantgarw then A468 east, but the route over Senghenydd Mountain is faster outside peak times and drops us straight into the upper valley.

Property type, climate, building age and infrastructure all behave differently in Caerphilly. Generic builders don't account for it. We do. ### Solid Stone Terraces, Same As Ponty The older Caerphilly and Senghenydd valley terraces are solid stone — they need lime plaster and breathable build-ups, not modern gypsum. We work this stock weekly and spec accordingly. ### Hill-Site Drainage Caerphilly and the surrounding valley villages sit on hillsides. Garden patios, extensions and retaining walls need engineered drainage to handle hillside run-off, especially after the heavy rain that funnels off Caerphilly Mountain. ### Render Failure On 70s-80s Estates The Bedwas, Trethomas, Llanbradach and Energlyn estates carry a lot of post-war and 70s sand-and-cement render that's cracking and blowing. Silicone render systems over the top stop the cycle. ### Cold-Bridging On Inter-War Semis The post-war and inter-war semis around Caerphilly typically have poor insulation continuity at floor and eaves junctions. Extensions and renovations are the right opportunity to design cold-bridging out — we detail for it as standard.
