Garratt’s is a leading London damp proofing contractor and basement waterproofing contractor working with developers and contractors across the city. As a family business, the company has over 70 years of experience helping to transform dark, wet, forgotten subterranean rooms into thriving spaces and homes, that add value to a property, as well as reinforcing their structural integrity.

Basement waterproofing London

As a leading waterproofing company in London, Garratt’s has worked across a range of different properties, including large commercial buildings, heritage and historical buildings, residential apartment blocks and individual homes. The company often works as the principal basement waterproofing contractor alongside architects, surveyors and property management companies on large-scale renovation and refurbishment projects, as well as advising on basement tanking solutions for new build developments.

Protecting the built environment against damp

In a densely packed city such as London, every inch of space is a valuable commercial entity. Ensuring that any underground area is protected against damp ingress and flooding will not only safeguard the integrity of the building as a whole, but will also reduce the financial risk posed by flooding or historic damp issues.

Over the decades, Garratt’s has built up a reputation as an experienced basement waterproofing contractor in and around the London area. As well as basement tanking systems we have developed a core list of services that addresses the full range of damp proofing issues, including wet and dry rot, condensation, penetrating damp, rising damp, basement flooding and tanking solutions.

Fully accredited water proofing solutions

We work as waterproofing contractors for main contractors and property managers across the city, providing fully accredited and professional services with standard 20 year guarantees for all general damp proofing work, and 10 year guarantees for all basement tanking systems. Garratt's are also an approved waterproofing contractor with Newton, Safeguard and Triton, with Delta approved technicians. These guarantee are assigned to the property, and are fully transferrable should the property be sold on.
