Damp Proofing Rickmansworth
Rickmansworth sits on the valley floor where three rivers and the Grand Union Canal meet, so groundwater and below-ground damp are part of the picture here in a way they are not in most towns, alongside the rising and penetrating damp of the older centre and the Metro-land estates. We diagnose the real cause and put it right. Survey-led, with a written 10 year guarantee.

Damp in Rickmansworth Property
Rickmansworth is defined by water. It gives Three Rivers its name, sitting on the valley floor where the Colne, Chess and Gade, all chalk streams, meet the Grand Union Canal. That makes it different to most of the towns we work in: the ground is river gravel and alluvium over chalk, the water table is high, and the town has flooded more than once over the years. The lakes of the Aquadrome are old gravel pits that filled with water once they were dug below the water table, which tells you how close that water sits to the surface.
For valley-floor, riverside and canal-side property that means ground damp and below-ground water are real risks, the kind that need proper below-ground waterproofing or tanking to BS 8102, not a damp proof course.
Away from the water there is the older town centre around St Mary's and the High Street, with solid-walled Georgian and Victorian homes prone to rising and penetrating damp, and the interwar Metro-land semis of the Cedars and Loudwater estates, where penetrating damp and condensation are more common. With that range, the only reliable starting point is a proper survey.

What Our Customers Say
Genuine reviews from Advanced Damp customers.
"Professional company and a great transformation. The area is a small below ground void that has a sloped cement retaining slab. They damproofed it and then came up with a great plan to add storage shelves. It looks great and has added the storage that we wanted."
"Lionel the surveyor arrived on time and he was very courteous and thorough, he discussed everything that needed doing and was able to reassure us during a very stressful time."
"Had the great experience for a Damp Survey. Very thorough on their report undertaken and prompt response to our enquiries. The very best of Lydia on sales and Lionel the surveyor. Highly recommended using their services."
