Rowden stretches from Chippenham's southern edge into the rural fringe, creating the most varied exposure of any Chippenham neighbourhood. Rural fringe properties have more wind exposure and a higher debris load than central streets.
1960s–70s estate housing in the northern sections; 1990s–2000s development at Methuen Park; occasional period farmhouse and cottage properties on the outer edge. Three distinct maintenance profiles in one area.
Nail sickness on 1960s–70s sections; flat roof extension failures on 1990s–2000s sections; and lime mortar requirements on rural fringe period properties. Mixed property types require broader material preparation than single-era areas.

01249 247 076Rowden is a Chippenham district on the southern edge of town mixing older Rowden Hill property with later 20th-century and modern housing. On this kind of stock, the problems we see most in Rowden are nail sickness on the mid-century stock, wind-lifted tiles on the exposed higher ground, and ageing felt on the older extensions. Rowden sits on rising ground on the south of Chippenham, its higher plots more exposed to wind.
For a new window we check rafter spacing, the room below and planning status; for a leak we diagnose the flashing.
Rear-slope installations are usually permitted development; front-slope, listed and conservation-area need checking first.
A fixed price for install or flashing repair, agreed before work.
The window is fitted and sealed with the correct flashing kit for your specific tile or slate profile.
We test for watertightness, make good internally where agreed, and guarantee the work.
| Job | Typical duration |
|---|---|
| Flashing kit repair | 2–4 hours |
| Replacement in existing opening | half to full day |
| New roof window (rear slope) | 1 day |
| Multiple windows | 1–2 days |
| Dormer roofing / repair | per scope |
Cutting a new opening needs dry conditions so the roof is never left open to rain; we weather-schedule new installations.
Rowden's mix ranges from tight older plots to open modern estates with driveway access for scaffold and skips. Scaffold and skip permits go through Wiltshire Council, and on the estate roads off Rowden Hill we allow extra time for setup. Access is always itemised in your written quote, never a hidden extra.
Workmanship carries our 10-year guarantee; the window and flashing kit carry manufacturer warranties (Velux units typically 10 years) on top.
