Damp Proofing in South London
Damp doesn’t just look unsightly, it can cause lasting damage to your home if left untreated. Roof Crest provides effective damp proofing solutions across London, tackling the problem at its source.

DAMP PROOFING
Expert Damp Proofing Solutions
Damp can show up in different ways, from rising damp and penetrating damp to condensation, and each requires a different approach to treat properly.
At Roof Crest, we start by identifying the type and cause of the damp before recommending a solution, whether that’s a damp proof course, tanking, ventilation improvements, or render repairs. We’ll explain exactly what’s needed and why, so you understand the problem rather than just being told it’s fixed.

What causes damp in a home?
Damp is usually caused by rising damp from the ground, penetrating damp through walls or roofs, or condensation from poor ventilation. We’ll identify the exact cause during our survey before recommending treatment.
How do I know if I have damp?
Common signs include musty smells, discoloured or peeling walls, damp patches, mould growth, and flaking paint or plaster. If you’re noticing any of these, it’s worth getting the property inspected.
How is damp treated?
Treatment depends on the type of damp. This might include installing a damp proof course, tanking, improving ventilation, or repairing render or brickwork. We’ll recommend the right approach for your specific problem.
How long does damp proofing take?
This depends on the extent of the damp and the treatment required. We’ll give you a realistic timeframe once we’ve assessed the property.
How much does damp proofing cost?
Cost depends on the cause and extent of the damp, along with the treatment needed. We’ll give you a fixed, no obligation quote after a free survey.
Will damp come back after treatment?
When treated correctly and the underlying cause is addressed, damp shouldn’t return. That’s why identifying the actual cause matters more than just treating the symptoms.
Is damp proofing disruptive?
It depends on the treatment required. We’ll talk you through what to expect and keep disruption to a minimum wherever possible.
