We’ve been successfully damp-proofing properties for trade clients for over 60 years.

Office buildings, mansion blocks, schools, hospitals, churches, houses, flats…

You name it, we’ve fixed it. And we’d be delighted to help you.

Everyone in our team is a skilled professional with decades of experience.

We have all the important accreditations you look for: CHAS, the PCA and Constructiononline.

We’re members of the British Structural Waterproofing Association.

You can be confident that your project will be in very good hands.

All our work is designed to last. In fact we’re so confident in our craftsmanship that we offer some of the longest guarantees in the industry – up to 50 years.

We take professional pride in doing a great job.

And we fully understand the demands of commercial projects, going out of our way to give you exactly what you need:

We’re the only damp-proofing company that offers a 50-year guarantee.

Exclusive 50-YEAR guarantee

1. Extremely high quality work, that lasts for years

Our surveyors have a huge amount of experience, allowing them to accurately identify every problem and pick just the right method to solve it. This is vital. Use the wrong method, and sooner or later the damp will be back.

Then our highly skilled fitters and plasterers carry out the work to an extremely high standard – keeping your client’s building dry for years to come, guaranteed.

2. Among the longest guarantees in the industry: up to 50 years

Depending on the type of job, we guarantee our work from 10 to 50 years. In fact we’re the only damp-proofing company that offers a 50-year guarantee. That’s how confident we are in the quality of our workmanship.

On the rare occasion that our work fails during the guarantee period, we’ll come and fix it as soon as we possibly can. No quibbles.

In addition, our guarantees can be underwritten by General Protection Insurance (GPI), giving you or your client extra peace of mind.

3. One-stop shop, with the full range of damp-proofing solutions

We are experts in the full range of damp-proofing methods:

  • chemical damp-coursing
  • physical damp-coursing
  • basement tanking & waterproofing
  • structural waterproofing
  • dry & wet rot treatment
  • woodworm & insect infestation, and
  • specialist replastering

Plus we are recognised fitting agents for industry leaders, Newton tanking systems and Safeguard products.

So whichever is the right system – or combination of systems – for your damp problem, we can install the best one for you.

4. Expert surveyors, fitters and plasterers, with decades of experience

Our professional surveyors are damp specialists with decades of experience.

Similarly our operators are long-serving staff with an average of 20 years’ working for us. They know the business inside and out.

We carry all the specialist tools for every type of damp problem and building. And we’ve used our own proprietary render for over 40 years – we know it keeps a building dry.

5. Vast industry experience & local knowledge

We’ve been in business for over 60 years and have vast knowledge of the rivers, streams, water table, areas of flooding, soil types and construction methods of London and the surrounding counties. Our know-how is immense.

We’ve built a database of some 40,000 surveys carried out in the area, and have carried out works in most roads listed in London.

We also have in-depth industry knowledge of all the damp-proofing solutions to deal with any problem.

And as the science behind damp eradication has progressed, we’ve literally been involved in writing the textbooks on damp-proofing.

Put all of this together, and it means that our guys will choose the best option for you or your client – saving you time, hassle and money.

6. Industry leaders in physical DPCs

Physical DPCs are extremely effective. But most companies don’t have the experience or the right tools to install them properly.

We are one of a handful of companies in the UK to offer a specialist physical DPC service.

We guarantee our physical DPCs for 50 years.

We’ve never had to go back to repair a physical DPC that we’ve installed – including DPCs installed over 60 years ago. That’s how effective they are when installed correctly.

7. Flexible arrangements to ensure your project runs smoothly

We know it can be a nightmare getting all your contractors to co-operate on a project.

We’ll do our utmost to make sure the work runs the way you want it to, by:

  • ​Dovetailing our work with other contractors.
  • Providing a dedicated account manager and surveyor to ensure smooth progress, and that we hit your deadlines.
  • And if you prefer to undertake the finishes in-house, or complete other areas of works by your own operatives, we can provide you with our proprietary materials and advice.

And last but not least…

8. Helpful office staff to take your calls

If you need to get in touch with us, we’ll answer the phone!

It sounds like a small thing, but you’ve probably dealt with contractors who rarely answer calls. This can be extremely frustrating when there’s a change in plans, or something important to discuss.

There’s always someone in our office to take your calls between 8.00am and 5.00pm. And even if your query is out of office hours, we’ll usually pick up and get back to you as quickly as possible.

How to get started

We’d be delighted to discuss the work you’re involved in, and how we could help. To get going, just give us a call or email to arrange an initial chat. Then we can talk over the phone, or arrange to meet in person. After that, if you’d like to take it forward, the next step would be to arrange for one of our surveyors to a make a site visit, and then send you a full report. ​If you have any questions, we’re more than happy to talk them through with you.
