Compare QuotesInspection Fees
Some contractors inspect for free and include the diagnosis in their repair quote. Others charge an assessment fee, roughly R800 - R2,500, more if a detailed written report is needed. Ask before the visit. See damp inspection.
What Affects the Cost
Access
Ladders, scaffolding, rope access or moving kitchen units and built-in cupboards all add cost.
Size of the affected area
More wall length or surface area means more material and labour. Larger jobs sometimes get a lower unit rate.
Treatment method
A clear sealer costs a fraction of a new membrane. External excavation costs far more than internal tanking.
Removal of damaged plaster
Hacking off salty plaster, rubble removal and skip hire are often priced separately.
Drying time
Walls need time to dry before replastering and painting, which can mean return visits.
Reinstatement
Replastering, skirtings, painting, retiling and garden or paving repairs may or may not be included.
What a Quote Should Include
- The diagnosed cause of the damp.
- Method and products to be used.
- Measured areas or lengths.
- Plaster removal, replastering, painting and rubble removal, or a clear statement that they are excluded.
- Drying time and timeline.
- Guarantee terms in writing.
- VAT, deposit and payment terms.
