3 Best Mold Removal Services in Johannesburg (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Fenris Morrow, Expert in Professional Services · ✓ Data verified August 2026 · 6 min read

Damp and mold in a Johannesburg home usually trace back to rising damp, a leaking roof, or poor waterproofing rather than the mold itself, so anyone searching for mold removal services in Johannesburg is really looking for someone who fixes the source. The three specialists on this page have logged 172 Google reviews between them, and all three sit above 4.0 stars, with Maintenance Aid holding both the highest rating and the deepest track record.

Short answer: Maintenance Aid leads with 4.8 stars across 93 reviews, the most of any damp and waterproofing specialist in Johannesburg on this page. Dampcon (4.7, 42 reviews) has operated since 1985, and Damp King (4.1, 37 reviews) rounds out the list. All three handle rising damp, waterproofing, and related repair work rather than mold removal alone, so expect a site assessment before any quote.

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the company’s live Google star average. Review volume is how many customers have rated them, ranked against the other Johannesburg specialists we found. Confidence weighs the rating by that volume, so a rating built on more reviews carries more weight than one built on a handful. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does mold or damp removal cost in Johannesburg?

None of the specialists on this page publish fixed mold or damp removal pricing online, and reviewers describe project-based quotes rather than a flat rate. Cost depends on the size of the affected area, whether the cause is rising damp, roof leaks, or waterproofing failure, and whether repainting or replastering is needed alongside the treatment itself.

Serving Johannesburg and surrounds

The specialists above are based in Highlands North, Booysens, and Randburg, and describe working across the greater Johannesburg and Pretoria area, including complexes and commercial buildings beyond the city centre.

What to ask before you hire a damp or mold specialist

Can you identify the underlying cause, such as rising damp, a roof leak, or condensation, before quoting a fix?
Does the quote include repainting or replastering after the treatment?
What warranty do you offer on the repair, and how long does it last?
Will a site supervisor check the work as it progresses?
Can you provide references from a similar-scale job?

Frequently asked questions

How did you choose these mold and damp specialists?

We started from mold, damp, and waterproofing specialists in Johannesburg with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Is mold removal the same as damp proofing?

Not exactly. Mold is often a symptom of an underlying damp problem, such as rising damp or a leaking roof. All three specialists on this page focus on waterproofing and damp proofing as the root fix, which is usually what stops mold from coming back.

Do these companies offer a warranty on their work?

Reviewers mention warranty coverage at Maintenance Aid specifically, including a multi-year warranty on roofing work. Confirm warranty length and what it covers directly with each company before booking, since terms vary by job type.

The bottom line

Maintenance Aid is the safe default with the highest rating and deepest review history here, while Dampcon is worth a call if a previous damp fix from another company has already failed. Get a written quote that names the root cause, not just the treatment, before any work begins.
