Damp Treatment Specialists

Getting the Diagnosis Right Before Any Work Starts

Damp shows up the same way regardless of its cause, as staining, a musty smell, crumbling plaster or peeling paint, but rising damp, penetrating damp and condensation each need a completely different fix. Treating the wrong one wastes your money and the problem simply returns.

Our team starts every job with a proper inspection to identify exactly what is causing the moisture, whether that is a failed damp proof course, a leaking gutter feeding water into the wall, poor ventilation, or bridged cavity walls. Only once we know the cause do we recommend a treatment plan.

Because we handle both the damp treatment and the plastering that follows, you get one team responsible for the whole job, with a finish that looks right and a problem that actually stays solved.

Our Damp & Plastering Services

Everything Covered Under This Service

From diagnosing the cause to the final coat of plaster, here is what is included in our damp proofing and plastering service.

Damp Diagnosis & Survey

A thorough inspection to identify whether you are dealing with rising, penetrating or condensation related damp.

Rising Damp Treatment

Installing or repairing a damp proof course and treating affected masonry to stop moisture rising through walls.

Penetrating Damp Repairs

Tracing and fixing the external source, whether that is render, pointing, gutters or window seals letting water in.

Condensation Control

Ventilation improvements and surface treatments that reduce mould growth caused by trapped moisture indoors.

Plaster Stripping

Removing damaged, blown or contaminated plaster ready for treatment and a fresh, sound surface.

Re-Plastering

Skilled plastering to a smooth, lasting finish on walls and ceilings, ready for decorating.

Salt Neutralising Treatments

Treating hygroscopic salts left behind by long-term damp, which can otherwise draw moisture back into new plaster.

Waterproofing below ground level spaces to keep cellars and basements dry and usable.

Ceiling Repairs

Repairing cracked or sagging ceilings caused by water damage or age, restored to a clean, flat finish.

Real Client Stories

What Our Damp & Plastering Clients Are Saying

Homeowners across Bristol and Keynsham trust MC Roofing & Landscapes to get to the root of damp problems.

“Had damp in the same corner of the lounge for years and two other companies just slapped on a coat of paint. MC actually traced it to a cracked gutter outside, fixed that first and then replastered properly.”

Eleanor Pascoe

“Rising damp in our hallway was clearly explained before any work started, which I really appreciated. New damp proof course fitted and replastered, no issues since.”

Reece Goddard

“Bathroom kept getting black mould no matter how often we cleaned it. Turned out to be a ventilation problem rather than a leak. Sorted properly and it has not come back.”

Got Questions

Damp Proofing & Plastering FAQs

Everything you need to know before booking your free damp survey.

How do I know if I have rising damp or penetrating damp?

Rising damp typically appears low on internal walls and worsens near the ground, while penetrating damp can appear at any height and usually links to an external defect such as render or roofing. Our free survey will confirm which you are dealing with.

How long does the plaster need to dry before decorating?

Fresh plaster typically needs around one week per millimetre of thickness to dry fully before painting, though this varies with ventilation and weather. We will give you a clear timeframe for your specific job.

Can condensation cause the same staining as damp?

Yes, condensation related mould can look similar to other types of damp, which is exactly why an accurate survey matters before any treatment is chosen.

Do you offer a warranty on damp treatment?

Yes, our damp proofing and plastering work is backed by our lifetime workmanship warranty for complete peace of mind.

Can you treat and replaster in the same visit programme?

Yes, we handle both the damp treatment and the plastering that follows as one project, so you only need to deal with a single team from start to finish.

Which areas do you cover for damp proofing?

We work from our Keynsham base out across Bristol and the neighbouring areas for damp and plastering jobs. Reach out with your location and we will confirm.
