FAQs
“How long have you been in business?”
ANSWER: Allerton Damp Proofing Ltd was founded in 1983 (and we’ve got our old typewriter to prove it!). Throughout our history, we have served thousands of customers and recently celebrated our 19,000th survey! As such, when you choose us, you can be assured that you are choosing experience and excellence.
“Do you guarantee your work?”
ANSWER: Yes we do. Where appropriate, we will issue to you a free 20 year guarantee with our work. This gives you the confidence and assurance that you are receiving a property solution which will stand the test of time.
Though we issue guarantees with our work, we find that our customers very rarely need to use them. In fact, in a recent survey, it was found that fewer than 99.9% of our customers needed to use their guarantees.
