Career Profile

Damp rising up from the ground is a big threat to all buildings – so damp proofers keep it out.

What they do

They lay damp proof membranes to prevent moisture seeping into a building from the earth. These are laid when new buildings go up but with old buildings, the damp proofing may be needed because the old layer has deteriorated or there wasn’t one in the first place.

For maintenance and replacement work, damp proofers drill holes into the building and fill with a liquid damp proof material such as silicone. They use a range of materials to seal the building from the damp ground beneath it.  

This is a physically demanding career and suits people who enjoy a very active working day.

Typical tasks include:

  • giving advice to the client or main contractor
  • identifying damp problems
  • cleaning and preparing the area
  • using specialist tools and different products to cure damp
  • dealing with any issues that come up with customers and projects


  • Newly trained damp proofer’s can earn in the region of £12,000 - £20,000
  • Trained with experience damp proofer’s can earn in the region of £20,000 - £30,000

Salaries typically range depending on location and overtime. Self-employed damp proofer’s set their own pay rates.
