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.
Roof Cleaning Across Chippenham Neighbourhoods
Moss growth rates vary across Chippenham's neighbourhoods depending on moisture exposure and tree cover. River-adjacent areas (Hartham, Monkton Park) see the fastest growth — 2-year cleaning cycles recommended. Central and elevated streets have moderate growth — 3–5 years. We use manual removal and soft-wash biocide on all Chippenham properties — no pressure washing, which damages protective coatings on concrete tile and can fracture aged clay tile.
A written inspection report is included with every cleaning visit — identifying any tiles, mortar or lead issues noted during the close-access cleaning work. Many repair recommendations originate from cleaning visits rather than specific surveys. Where the roof is approaching an age threshold, we note this clearly in the report.

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. Inspect & access
We assess the moss coverage, tile type and condition, and set up safe access.
2. Manual removal
Moss is scraped and brushed off by hand — never pressure washed, which damages tiles.
3. Biocide treatment
A biocide is applied to kill remaining spores and slow regrowth over the following seasons.
4. Clear the gutters
We clear the moss debris from the gutters so it doesn't wash back down.
5. Report
A written note of anything we spot up there, with no obligation to book it.

Access
Access & Scaffolding in Hartham
Hartham's riverside and estate properties vary from tight period plots to open grounds; period and stone stock often needs matching materials. Scaffold and skip permits go through Wiltshire Council, and on the lanes toward Hartham Park we allow extra time for setup. Access is always itemised in your written quote, never a hidden extra.

Your Guarantee
The clean and biocide are guaranteed for workmanship; regrowth timescales depend on aspect and canopy, and we're honest that no single treatment is permanent.
