Why This Matters Here

Why Hartham Specifically
Local Climate and Exposure
Hartham sits alongside the River Avon between Chippenham town centre and the rural south. The riverside location creates the highest moisture exposure in the Chippenham area — lead corrosion is measurably faster here, and moss growth on north-facing slopes is the most aggressive in our coverage.
Housing Stock Profile
Victorian and Edwardian properties near the river with post-war housing further inland. The riverside Victorian stock has some of the most demanding maintenance profiles in Chippenham due to the combination of age and moisture exposure.
The Most Common Call from Hartham
Lead valley and flashing failures accelerated by river moisture are the primary call — we specify code 5 lead on exposed riverside elements as standard. Aggressive moss on north-facing slopes is the secondary maintenance category.
What Makes Hartham Different
The River Avon creates conditions at Hartham that require specification adjustments compared to inland Chippenham properties. Code 5 lead, 2-year moss cleaning cycles, and annual gutter clearing are standard recommendations here.
Standard domestic rear-slope installations: usually permitted development. Front-slope: may need householder consent. We check during the survey.
Usually not. Most leaking Velux windows have a failed flashing kit, not a failed window. Flashing kit replacement costs £150–£350 versus £400–£700 for a new window.
Hartham is 1 mile from our Chippenham base — under 10 min. No travel surcharge.
Yes — we work with loft conversion builders across Hartham and all of Chippenham. We handle the roofing element and coordinate with the build programme.
Velux recommends a minimum of 10% of floor area as glazed area. Two standard pivot windows (78×98cm) usually meet this for a typical loft bedroom.
Internal condensation indicates insufficient ventilation — not a window fault. Solutions include trickle ventilators or improved mechanical ventilation.

Hartham is a riverside area north of Chippenham with a mix of older stone and brick property and Hartham Park's period estate, close to the Avon watermeadows. On this kind of stock, the problems we see most in Hartham are heavy moss on the shaded riverside roofs, blocked valleys from the mature tree cover, and leadwork on the older period stock. Hartham sits right on the Avon, so humidity is high, moss growth fast and drying slow, especially on the riverside slopes.

How the Job Runs in Hartham
1. Assess the opening
For a new window we check rafter spacing, the room below and planning status; for a leak we diagnose the flashing.
2. Confirm planning
Rear-slope installations are usually permitted development; front-slope, listed and conservation-area need checking first.
3. Written quote
A fixed price for install or flashing repair, agreed before work.
4. Install & flash
The window is fitted and sealed with the correct flashing kit for your specific tile or slate profile.
5. Test & finish
We test for watertightness, make good internally where agreed, and guarantee the work.
