How much does it cost to hire a damp proofing company?
How much you end up spending on damp proofing will depend heavily on the type of damp you have (rising, penetrating, or condensation) and the treatment required. The most common methods include injecting a chemical damp proof course (DPC), structural basement tanking, or installing mechanical ventilation systems. The size of the affected area and where you live in the UK will also impact costs.
The average cost to treat a single damp wall using a chemical injection typically ranges between £300 and £1,000, while a full property damp proof course can cost anywhere from £2,000 to £6,000+.

Factors to consider when choosing a damp proofing specialist
An effectively damp-proofed property can transform your home’s interior, turning a cold, musty environment into a warm, healthy, and comfortable space to live in. What’s more, it will eliminate the stress of dealing with peeling wallpaper, crumbling plaster, and hazardous mold growth that can affect your family's respiratory health. Investing in damp proofing also protects the core structural integrity of your building, keeping its value high and making it much more appealing to future buyers or renters.
A damp proofing specialist can help you with:
- Diagnosing the root cause of moisture issues using calibrated damp meters and thermal imaging.
- Injecting new chemical damp proof courses or replacing physically damaged DPCs.
- Cellar and basement tanking (applying waterproof membranes or coatings to below-ground walls).
- Removing salt-contaminated plaster and applying specialized, salt-resistant replastering.
- Installing continuous positive input ventilation (PIV) systems to permanently eradicate condensation.
Damp proofing specialists don’t just mask stains with anti-damp paint. They locate hidden defects like blocked cavity walls, failed external rendering, or bridged DPCs, ensuring the moisture is stopped at the source before any internal cosmetic repairs begin.
Looking after your property’s moisture barriers is incredibly important, as leaving damp untreated can lead to devastating wood-rotting fungi like dry rot or wet rot in your floorboards and joists. If your home is showing signs of damp, a local specialist can get it permanently back into a dry, healthy shape.

Other damp proofing FAQs
How long does it take to complete a damp proofing treatment?
For a standard terraced or semi-detached home requiring a new injected damp proof course on a couple of walls, the process usually takes 2 to 4 days. This timeline includes drilling the masonry, injecting the cream or fluid, stripping back the contaminated plaster, and applying the specialist salt-retardant backing plaster.
Does damp proofing require planning permission or building regulations?
Standard damp proofing treatments on existing homes do not require planning permission, though you must seek consent if your building is listed. However, under UK Building Regulations, any replacement of internal plaster down to the masonry or installation of a new DPC must comply with moisture resistance standards and should ideally be carried out by a certified specialist who can provide a compliance certificate.
How do I prepare my home for a damp proofing treatment?
To prepare for your specialist’s visit, clear all furniture, ornaments, and floor coverings at least one to two meters away from the affected walls to give the team ample room to work. Because stripping plaster creates significant heavy dust, you should also cover nearby fixed items and doorways with plastic sheeting to protect the rest of your home.
