Damp Proofing & Prevention
Kent, East Sussex, & West Sussex
Tired of patching the same damp problem again and again?
You're not imagining things — that musty smell, the peeling paint, the cold, clammy feeling in your home. Damp is one of the most common and destructive problems facing UK homeowners, especially in older properties across Kent, West Sussex, and East Sussex.
What starts as a small damp patch can turn into full-blown mould, timber rot, and crumbling plaster. It doesn’t just make your home feel uncomfortable — it reduces your property value and poses serious health risks.
Renovani Ltd is here to fix it for good.
Damp is more than just a cosmetic issue
When left untreated, damp leads to:
Rotting skirting boards and flooring
Crumbling plaster and ruined decor
Cold, uncomfortable rooms
Persistent mould and mildew growth
Health problems like allergies and respiratory issues
Expensive structural repairs down the line
Our goal isn’t just to treat the symptoms — it’s to find the source, fix it, and keep your home dry and healthy for years to come.
What type of damp are you dealing with?
Rising Damp
Moisture rising from the ground into your walls and floors.
Common signs include:
Damp patches near the base of walls
Bubbling or peeling wallpaper
White salt marks on paint or plaster
A musty smell near floor level
Damage to skirting boards or wooden floors
Solution:
We install or repair damp-proof courses (DPC), apply specialist internal wall treatments, and protect your timber from decay.
Penetrating Damp
Water entering your home from outside — usually through leaks, cracks, or poor drainage.
You might notice:
Water stains or damp patches after rain
Mould growth on walls or ceilings
Flaky paint or wallpaper
A musty smell in one specific area
Solution:
We locate the source — whether it's a cracked brick, blocked gutter, or leaking roof — and fix it. Then we dry, treat, and restore the interior.

Frequently Asked Questions (FAQs)
Q: How do I know if it’s rising damp or penetrating damp?
Rising damp typically affects lower walls and shows salt marks, while penetrating damp can appear anywhere, especially after rain. During our survey, we’ll diagnose it properly and explain your options.
Q: Can damp proofing really stop the problem for good?
Yes — if done correctly. We focus on finding and treating the root cause, not just painting over it. Our work is guaranteed.
Q: Will I need to leave the house during the work?
Usually not. We plan around your schedule and work in sections to minimise disruption.
Q: Is your survey free?
Yes — our initial site survey is free, and we’ll provide a no-obligation quote with clear next steps.
Q: How long does the work take?
That depends on the extent of the damp and size of your property. Most treatments take 1–3 days.
