Damp proofing services
Damp Proofing Gauteng Homeowners Trust
AB Restorations delivers the damp proofing Gauteng homeowners trust, tracking rising and penetrating damp to its source, treating the wall and making good the damage. Every job is backed by a written 12-month workmanship guarantee.
Rising Damp Specialists
Rising, penetrating and condensation damp, each treated its own way.
Insurance Approved
An approved contractor for damp and water-damage claims.
12-Month Guarantee
Every damp treatment is backed by a written guarantee.
We Treat the Cause
We stop the moisture at the source, not just the stain on the wall.
Why it matters
The damp proofing Gauteng walls need to dry out for good
Damp does not fix itself. Rising damp climbs up from the ground, penetrating damp pushes in through walls, and condensation settles wherever the air cannot move. All three leave the same marks: stained walls, blistering paint, a musty smell and plaster that crumbles when you touch it.
We work out which type of damp you have and where the moisture is coming from, then treat the cause before we repair the damage. That is the difference between damp that stays gone and damp that is back by next winter.

Retaining and Below-Ground Walls
Tanking and sealing for retaining walls and rooms below ground where moisture pushes in.
How we work
Our damp proofing process
Four clear steps, from the first moisture reading to a re-plastered wall backed in writing.
Assessment and moisture reading
We inspect the wall, take moisture readings and work out exactly which type of damp you are dealing with.
Strip back and prepare
We remove the blown, salt-damaged plaster back to sound brick so the treatment can do its job.
Treat and seal
We install the correct damp course or sealing system to block the moisture at its source.
Re-plaster and guarantee
We re-plaster with a salt-resistant mix, leave the wall ready for paint and hand over your 12-month guarantee.
Peace of mind
Treated at the source, and guaranteed in writing

Damp proofing questions
Frequently Asked Questions
What causes rising damp?
Rising damp happens when there is no working damp-proof course in the wall, so moisture from the ground soaks up through the bricks. You usually see it as a tide mark, blistering paint or crumbling plaster up to about a metre off the floor.
What is the difference between rising and penetrating damp?
Rising damp travels upward from the ground through the wall, while penetrating damp pushes inward through cracks, walls or a leaking roof after rain. They look similar but need different treatments, which is why we diagnose the cause before quoting a fix.
How long does the wall take to dry out?
The treatment itself is quick, but a wall that has held damp for years needs time to dry once the moisture is cut off. Fresh plaster is usually ready for paint within a few weeks, and we tell you what to expect on the day.
Will the damp come back?
Not when the cause is treated properly. Damp comes back when someone only paints over it. We stop the moisture at the source and re-plaster the wall, then back the work with our 12-month guarantee.
Do you repair the plaster and paint afterwards?
Yes. We strip the damaged plaster, re-plaster with a salt-resistant system and leave the wall smooth and ready for paint. We can handle the painting too if you would like it finished in one go.
Which areas in Gauteng do you cover?
We treat damp in homes across the whole of Gauteng. Pretoria, Johannesburg, Kempton Park, Centurion, Midrand, Benoni, Boksburg and the wider East Rand are all regular stops for our team.
