Damp Proofing Specialists

We are Anke Damp Proofing, a family-run business based in Welwyn Garden City, Hertfordshire. Anke Damp Proofing was founded in 2016 to provide specialist damp and waterproofing services. We cover the Hertfordshire, London, Bedfordshire, Cambridgeshire and Essex area offering a range of professional property services.

No Hard Sell

Unlike many similar businesses in the damp-proofing industry, our team is all salaried including our surveyors. Without the pressure to earn a commission, our staff don’t oversell services or pressure customers to buy treatments they don’t need. In fact, much of our work is purely advisory with no obligation to purchase our services.
