Get Waterproofing QuotesTypical Jobs in Wellington
- Damp proofing. Damp walls, mould and salts in older homes.
- Rising damp treatment. Chemical damp-proof course injection and replastering.
- Metal roof waterproofing. Corrugated and IBR roofs on homes, sheds and stores.
- Wall waterproofing. Cracked outside walls letting in winter rain.
- Dam waterproofing. Farm dams that lose water through seepage.
Older Houses: What Usually Fails
- Damp-proof course. Old courses fail or get bridged by raised paving, flower beds or new plaster.
- Cement plaster. Hard cement plaster can trap moisture in older walls.
- Gutters and downpipes. Overflowing gutters soak the base of walls every winter.
Fixing gutters and lowering soil against walls is cheap and sometimes solves the problem.

- Wall length. Damp treatment is priced per metre of affected wall.
- Replastering. Hacking off and replastering adds most of the cost.
- Drying time. Walls need weeks to dry before final paint.
- Dam size. Large dams cost less per m² but need earthworks and anchoring.
How a Damp Job Usually Runs
- Assess. Moisture readings and a look at ground levels, gutters and plaster.
- Treat the cause. Inject a new damp-proof course or fix the water source.
- Replaster. Remove salt-damaged plaster and replaster with a salt-resistant mix.
- Dry and paint. Let walls dry, then paint with a breathable finish.
Questions to Ask
- Is this rising damp, penetrating damp or a plumbing leak?

- How long before I can paint?
- What guarantee is given on the damp-proof course?
Waterproofing Wellington FAQs
How do I know if it is rising damp?
Rising damp usually shows as a tide mark up to about a metre, with salts and flaking paint. A moisture test rules out leaks and condensation.
Will painting over damp fix it?
No. Waterproof paint over rising damp traps moisture and the problem returns. The cause must be treated first.
Can farm dams be lined?
Yes. HDPE or similar liners are common. Larger dams may need an engineer.
How long does damp treatment take?
Injection and replastering of a few rooms takes a few days, but drying takes longer.
