Our Experience

Allerton Damp Proofing was founded in 1983 with the objective of providing expert property services, with honesty and integrity.  In all of our 33 years, we have succeeded in achieving these goals, but we certainly aren’t resting on our laurels.  We continue to strive for excellence and our dedication to quality, and outstanding customer service is such that we are regarded as leaders in our industry.

Our Commitment

To us, commitment means working with speed to finish a job on-time, but always taking the time to ensure that a job is finished correctly and to a high standard.

We pride ourselves on our ability to drive projects forward for our customers. We realise that any home improvement project causes some upheaval and inconvenience for the occupants and as part of our commitment to quality, we ensure that all projects which we carry out are finished quickly, cleanly and to a high standard.

Expert Property Services

Though we have been around much longer than our industry regulator, the Property Care Association (PCA), we have been a member since its foundation in 2003. Our surveyors are Certified Surveyors in Remedial Treatments (CSRT) in accordance with the PCA’s requirements; CSRT is the expert qualification for the diagnosis of damp and timber-related defects in properties. Similarly, our Technicians are certified PCAQTs (Qualified Technicians), making them experts in carrying out the works that our surveyors recommend.

Safe Working

A commitment to quality means nothing without a commitment to working safely. As such, we are certified by the the Contractors Health and Safety Assessment Scheme (CHAS) for which we must regularly demonstrate our dedication to safety. The CHAS mark guarantees to our customers that their safety will be safeguarded by our experts throughout any works which we carry out for them.

We’re never happy unless we’re making you happy. Part of our great service to you is ensuring that we uphold our values which we call ‘the two pillars’. Why are they called that? Well, they are the foundation of our business, without which we couldn’t exist. Find out more about the two pillars below.



Unlike many of our competitors, our surveyors do not work for commission. We believe that the incentive of commission has blighted our industry, with surveyors trying to increase their earnings by over-quoting or quoting for unnecessary work. At Allerton Damp Proofing, we offer incentives to our staff are for outstanding customer service, nothing more.



To us, integrity in our work means that we provide customer care that lasts. To this effect, we provide comprehensive 20 year guarantees with our work, which is 10 years longer than many of our nearest competitors. In addition, we are authorised by the PCA to offer specialist Guarantee Protection Insurance, which some customers might be asked to obtain if they are in the process of selling their homes.

Our damp proofing guarantee

When you receive advice or a survey report from us, you can be sure that it represents an honest and expert opinion of the condition of your property. It will not contain any hard-sell or recommendations for unnecessary action. Additionally, you can be confident that any quotation that we provide to you is an honest reflection of the work that it relates to.

Trading Standards Experts, giving you the confidence that, when you choose us, you are choosing excellence.

As part of choosing us, you will automatically gain the protection that consumers get through the Which? Trusted Traders Scheme. This includes access to the Which? arbitration and complaints service, as well as a whole host of other benefits.

We always endeavour to provide the best service and products for our customers. However, on rare occasions, we recognise there may be times where our customers may not be completely satisfied.

“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.

Please note that, as a provider of essential services, we are still open for business, with some restrictions. As a new or existing customer, you can continue to call us to discuss new or existing projects.

Please note that we have had to restrict our work in occupied homes considerably, due to the risk that this might pose to our customers and workforce. However, our work in empty homes and properties continues largely as normal.

If you would like to speak to a member of our team about anything to do with our work during the COVID-19 crisis, please contact us, as normal, using any of the contact details on this site.
