Get Waterproofing QuotesWhat Observatory Homes Commonly Need
- Rising damp treatment. Damp walls and flaking paint low down.
- Damp proofing. Damp from leaking gutters, sills and parapets.
- Roof leak repairs. Leaks at chimneys, valleys and old flashings.
- Metal roof waterproofing. Corrugated roofs with loose laps and rust.
Damp in Older Houses
- Bridged damp courses. Raised floors, paving or soil let moisture past the damp course.
- Mould in winter. Cold rooms with little ventilation get condensation.
- Rental homes. Landlords and tenants should agree who fixes the cause.

Get Waterproofing QuotesWhat Affects the Quote
- Cause. Rising damp, leaks and condensation are fixed differently.
- Replastering. Salt-damaged plaster adds cost.
- Roof condition. Old sheeting may need replacing before coating.
Timing Around Winter
- Book damp work in summer so walls can dry.
- Make temporary roof repairs before the rains.
- Ventilate rooms to reduce condensation while waiting.
Questions to Ask
- How did you rule out condensation?
- Will you fix bridging paving or soil?
- Is the roof sheeting sound enough to coat?
Waterproofing Observatory FAQs
Can mould be fixed with waterproofing?
Not if it is condensation. Ventilation and heating help; a damp assessment confirms the cause.
How long until treated walls dry?
Often several months, depending on wall thickness and weather.
Should the landlord pay for damp repairs?
Usually structural damp is the owner’s responsibility, but check the lease.
How much does damp treatment cost?
Ballpark R350 to R900 per metre for injection, more with replastering.
