Get Waterproofing QuotesWhat Melville Homes Commonly Need
- Damp proofing. Damp walls in older houses, often with more than one cause.
- Rising damp treatment. Failed or bridged damp courses under older brick walls.
- Metal roof waterproofing. Older corrugated iron roofs with rust, loose screws and leaking laps.
- Roof leak repairs. Flashings at chimneys, parapets and lean-to roofs.
- Wall waterproofing. Cracked render and parapets letting rain into walls.
Bridged Damp Courses
In many older homes, paving, garden beds or added layers of plaster sit above the damp course, so moisture climbs past it.
- Raised paving. Paving laid higher than the damp course lets splash and ground water into walls.
- Garden beds. Soil against outside walls keeps the base of the wall wet.
- Plaster over the damp course. External plaster that bridges the damp course carries moisture upward.
Lowering ground levels can be part of the fix, not only injection.

Get Waterproofing QuotesWhat Affects the Quote
- Cause of damp. Lowering paving or beds, gutter repairs or injection each cost differently.
- Roof sheet condition. Badly rusted sheets need replacing, not coating.
- Wall length. Damp work is priced per metre.
- Access. Narrow side passages and attached neighbours can slow work.
- Finishes. Replastering and repainting add to the total.
Timing Around the Rains
Storms show up rusted laps and tired flashings quickly. Treat damp and coat roofs in the dry season, and keep a temporary repair option for summer leaks.
Heritage Check
Some older homes may be heritage-sensitive. Check before changing the look of roofs, facades or boundary walls. Most damp and leak repairs do not change how a house looks.
Questions to Ask
- What is causing the damp, and is it more than one thing?
- Should ground levels be lowered before injection?
- Are the roof sheets sound enough to coat?
- Will you replace rusted screws and washers?
- What guarantee comes with the work?
Waterproofing Melville FAQs
Can an old corrugated roof be coated instead of replaced?
Yes, if the sheets are still sound. Rust is treated, screws replaced and laps sealed before the coating. Rusted-through sheets need replacing.
Why did damp come back after treatment?
Common reasons are a bridged damp course, salt-damaged plaster left on the wall or a second cause such as a leaking gutter.
Do I need to move garden beds away from the wall?
If soil is above the damp course, lowering it is often part of the fix.
What does metal roof coating cost?
Ballpark R120 to R280 per m², plus rust treatment and any screw or sheet replacement.
