Get Waterproofing QuotesSigns of Penetrating Damp
- Patches after rain. Damp that appears or spreads after storms.
- Damp high on the wall. Not limited to the bottom metre.
- Stains around windows. Water tracking from sills and frames.
- Cracked plaster outside. Hairline or structural cracks on weather-facing walls.
Where Water Gets In
- Cracks. Plaster and structural cracks let rain in.
- Parapets and copings. Flat tops of walls with no or failed waterproofing.
- Sills and frames. Failed sealant or sills without a drip.
- Porous walls. Face brick and old plaster that absorb driving rain.
- Gutters and downpipes. Overflowing or leaking water running down walls.
Methods
- Crack repair. Raking out and filling with flexible filler or mortar.
- Elastomeric wall coatings. Flexible waterproof paint systems for plastered walls.
- Clear water repellents. For face brick that should keep its look.
- Parapet waterproofing. Membrane or coating over the top and down the inside.
- Resealing windows. New sealant around frames and sills.
Coatings will not stop rising damp or a plumbing leak. The cause needs to be confirmed first.

Get Waterproofing QuotesWhat Affects the Quote
- Wall area. Coatings are priced per m².
- Number and size of cracks. Structural cracks may need an engineer.
- Height and access. Scaffolding adds cost on double storeys.
- Surface prep. Washing, scraping and priming old paint.
How the Work Usually Runs
- Inspect. Find where water enters, ideally after rain.
- Prepare. Clean, scrape and repair cracks.
- Prime. Seal the surface so coatings bond.
- Coat. Two or more coats at the right thickness.
Preparation and Disruption
- Dry weather. Coatings need dry days to apply and cure.
- Garden and paving. Plants near walls may need cutting back.
- Paint smell. Expect some fumes on solvent-based products.
Maintenance and Questions
- Inspect yearly. Check cracks, sills and parapets before the rainy season.
- Clear gutters. Keep water off walls.
- Ask. Which product and how many coats?
- Ask. Is crack repair included in the m² rate?
- Ask. What written warranty applies?
Wall Waterproofing FAQs
Is waterproof paint enough for wet walls?
Only if the problem is rain soaking through. It will not fix rising damp or leaks.
Can face brick be waterproofed without painting it?
Yes. Clear water repellents keep the look of the brick, but cracks and joints still need repair.
What about parapet walls?
Parapets are a common leak point and usually need a membrane or coating over the top.
Do I need scaffolding?
Often for double-storey walls. Ask whether it is included in the quote.
