“Excellent service from start to finish. The survey was thorough and professional, with honest, evidence-based advice rather than trying to sell unnecessary work. I came away with complete peace of mind.”

“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

Our specialists regularly work throughout Christchurch and the surrounding neighbourhoods.
What causes mould in Christchurch homes
Damp sea air, homes that have been sealed up for energy efficiency and a lot of single-storey living all play a part.
Humid coastal air
Air off the harbour and the Solent is often already moist, so it takes less cooking, showering and drying washing indoors to reach the point where condensation forms.
Bungalows with cold ceilings
Christchurch has many bungalows and chalet homes. Patchy loft insulation leaves cold ceiling corners and room-in-roof walls where mould takes hold first.
Sealed-up homes
New windows, blocked vents and draught-proofing cut heat loss, but they also trap moisture. Without a way for damp air to escape, mould follows.
How we remove mould in Christchurch
1. Measure, don’t guess
We log humidity, surface temperatures and moisture in the walls to tell condensation apart from penetrating or rising damp.
2. Treat it safely
Affected areas are treated with professional anti-microbial products, and mould-damaged sealant, silicone or plaster is removed where needed.
3. Stop it coming back
Positive Input Ventilation (PIV), humidistat extractor fans, insulation upgrades or damp repairs — matched to what we found.
Services we provide in Christchurch
Every service is delivered by our own in-house team and backed by our 25-year guarantee.
Your local damp, mould & timber team in Christchurch
Many of the Christchurch homes we visit are bungalows or chalet bungalows owned by people who have lived there for years and have never had a mould problem until new windows went in. A single PIV unit in the loft often transforms these homes, quietly pushing filtered air through and keeping humidity down. Where mould is a sign of damp coming through the walls instead, we will show you the readings and fix that first.
Built to impress, built to last
Diagnosis first
We identify the real cause before recommending any treatment. No guesswork, and never unnecessary work.
In-house specialist team
Vetted, Proofterior-trained specialists, managed by us from survey to completion. No compromises.
25-year guarantee
Every treatment is backed by our 25-year insured guarantee, giving you lasting protection and peace of mind.

Everything you might be wondering
Usually, yes. Bungalows suit loft-mounted PIV units very well because the fresh air reaches every room easily. We check your loft space and layout during the survey before recommending one.
Mould spores can aggravate asthma, allergies and breathing problems, especially for children, older people and anyone with a weakened immune system. It is worth dealing with promptly rather than repainting over it.
Bleach can lighten the stain on the surface but does not deal with the moisture that feeds the mould, so it soon returns. Lasting removal means fixing the humidity or damp behind it.
