How Mould Affects Your Weston-super-Mare Home – and How Damp Surveys, Timber Treatment & Tanking Help
Love your home in Weston‑super‑Mare? As a local damp proofing contractor, we know how winning the fight against damp depends on smart tactics like damp surveys, timber treatment, effective tanking, and targeted mould treatment. Let’s tackle the problem where it starts—right at home.

Mould, Scourge of the Seaside Property
Living in Weston‑super‑Mare comes with seaside charm, but it also brings moisture challenges. Salt-laden air, cool mornings, and homes built before modern insulation can make condensation a daily battle. When moisture lingers on window sills or cold corners, mould spores settle in, feeding off your walls, timber and soft furnishings. It doesn’t just look unpleasant—it can damage your property and affect your health too. That’s where we come in as a local damp proofing contractor, offering services from damp surveys to timber treatment, mould treatment, and tanking.
This blog is your go-to guide for understanding why mould shows up in coastal homes, how we tackle it properly, and why installing the right system makes all the difference.
How Mould Impacts Health & Property
- Health concerns – Black mould often releases spores that can trigger coughs, sneezes, and breathing problems, especially in children or asthma sufferers. It can also worsen allergies and lead to persistent rhinitis.
- Home damage – Mould eats into paint, plaster, and timber, causing discolouration and decay. Without prompt timber treatment, structural components like skirting boards and window frames suffer too.
- Air quality drop – Air in mouldy rooms can feel stale and damp, and poor ventilation doesn’t help. Over time, whole rooms—or even entire flats—can suffer from poor indoor air.
That’s why a proper damp proofing contractor steps in with smart solutions like damp surveys, tanking, timber treatment, and thorough mould treatment.


How Mould Treatment Works
- Damp surveys – First, our survey team checks your property for hidden sources of mould—moisture trails, timber rot, condensation hotspots. We use moisture meters and inspections to get to the root of the problem.
- Surface mould removal – We treat visible mould with fungicidal washes, scrubbing away stains and sanitising surfaces. No hidden specks left behind—we clean it properly.
- Timber treatment (if needed) – If mould has penetrated woodwork, we apply specialist timber treatment solutions that protect against decay and future infestations. This keeps floorboards, frames and skirting safe.
- Tanking alternatives (for severe damp) – In spaces like basements or storage areas, moisture may come from walls rather than condensation. That’s where tanking comes in—a waterproof membrane or cementitious barrier seals things off.
- PIV Installation – the game-changer – The real secret weapon is Positive Input Ventilation (PIV). Modern, discreet, and low-energy, PIV installation systems continuously pump filtered air into your loft. That subtle airflow pushes stale, moist air out through trickle vents. No fuss, no draught—just constant mould prevention.
Benefits of PIV Systems
- Reduces condensation by keeping air fresh and dry
- Helps fight mould and mustiness year-round
- Filters air and can mitigate allergens
- Very quiet—almost unnoticeable once installed
- Low maintenance—just an annual service
In Weston‑super‑Mare, where coastal humidity can sneak indoors, a good PIV system is one of the best investments you can make for your health and home.


Real Results: Local Homes Get Fresh Again
We’ve helped families across Weston‑super‑Mare reclaim damp rooms and restore comfort. In one case, bedroom mould stains and recurring coughs vanished within weeks of installing a PIV system. In another, careful timber treatment saved skirting boards ravaged by mould and neglected rot. And in downstairs storage rooms, simple tanking transformed unusable areas into dry, safe spaces.
Tips to Reduce Mould Between Visits
While professional help is key, there are things you can do right now:
- Open trickle vents or window locks slightly during and after showers
- Avoid drying clothes on radiators indoors
- Use extractor fans when cooking
- Keep furniture a few centimetres from walls to help air flow
- Keep the loft space ventilated
These steps help your mould treatment and PIV installation work better—keeping your home fresh long-term.
