Your big risk: cheap damp proofing that fails

The building trade doesn’t have a great reputation. And damp-proofing companies are no exception.

Many operators want to cash in quick, demanding payment up-front before they even start. This is even true of some of the most well-known companies. They promise you everything at low prices. Then afterwards you realise the work wasn’t up to standard. Believe me, we see a lot of these jobs!

You can easily end up with a damp problem that comes back in a year or two. You have to chase them to fix it. Or you end up paying a different company to do the job all over again. An expensive headache.

Obviously you don’t want to be in that situation. And we don’t want it to happen to you either.

Here at Dampcoursing Ltd we have a very different approach.

High quality work & full guarantees

We want you to be 100% satisfied.

We only invoice you after we’ve done the work and you’re entirely happy.

As a team of experienced professionals with decades in the industry, we take great pride in our craftsmanship.

And on the rare occasion that something does go wrong, we take full responsibility for fixing it.

For your peace of mind we provide a written guarantee for every job we do.

Not only this, but our guarantees are among the longest in the industry. That’s how confident we are in our work.

We always honour our guarantees. No ifs or buts. So if anything goes wrong during the guarantee period we’ll come back and fix it for you at no cost.

And if you end up selling your property, our guarantees are transferrable to the new owners.

This can be invaluable to you.

Potential buyers will be wary about damp issues. But with our guarantees in place you’ll be able to demonstrate that everything has been comprehensively dealt with, and that the new owners are fully covered.

Hugely experienced surveyors to assess your problem

Our surveyors have decades of experience in the underlying causes of damp.

Everything from the water table, rivers, streams, reservoirs and areas of flooding, to soil types and construction methods across London its suburbs. Their know-how is immense.

Plus we have in-depth industry knowledge of the many different kinds of damp-proofing solutions – from waterproof renders and chemicals to dampcoursing, tanking and pumps – to find exactly the right solution to fix your unique issue.

Our surveyors will provide you with a comprehensive survey and report. They’ll explain where the damp is coming from and identify exactly the right option for you – making sure your property stays damp-free for years to come, and saving you time, worries, hassle and money.

Honest, professional advice you can trust

It’s always tricky employing people to do specialist work you don’t fully understand. You can’t help wondering: Is all this work necessary? Or have some extras been added to bump up the bill?

Let me reassure you: our surveyors will never recommend any work you don’t actually need.

Our surveyors are not paid commission. They don’t get paid a bonus for additional work they bring in.

In other words, they’re not trying to make extra money out of you. Their sole interest is in doing a thorough, professional job – identifying the cause of your problem, and advising you of the best method of fixing it.

In fact out of every ten surveys they do, there are always one or two where they don’t recommend that we do any work. Usually this is because there isn’t a rising damp problem at all, but something like a leaky gutter or faulty plumbing that can be easily fixed.

Compared to some less scrupulous companies, you can trust the advice and recommendations we give you. And you can be sure that our quotation will only be for work that is actually required.

Full range of damp-proofing treatments

We have specialist expertise in the full range of damp-proofing treatments.

This includes:

  • Chemical damp-coursing
  • Physical damp-coursing
  • Basement tanking & waterproofing
  • Structural waterproofing
  • Dry and wet rot treatment
  • Woodworm and insect infestation, and
  • Specialist re-plastering.

We don’t just have a couple of ‘standard’ methods to draw upon.

Instead we provide you with exactly the right solution, using a combination of techniques to cure your particular problem.

Expert fitters and plasterers

Our team of expert fitters and plasterers – who are all long-serving staff, each having an average of over 20 years in the industry – ensure your job is done professionally, to exacting standards.

Just as important, they will always make sure that your property is carefully protected from the work, and leave everything neat and tidy afterwards.

Our own special materials, for the most durable solution

Standard construction materials – like ordinary plaster, cheap chemical injections and tanking – can deteriorate quite rapidly, and at worst may not work at all.

As well as using best-in-trade materials, we have our own proprietary materials, specially designed to keep the damp at bay.

Thanks to our extensive experience we know exactly which materials will work best to deal with your problem.

Specialists in physical damp-proofing: the most long-lasting cure of all

Amongst the wide range of solutions we offer, we are one of a handful of companies in the UK that specialise in physical replacement damp-coursing – a method that is practically infallible.

Put it this way: we’ve never had to go back to repair a physical damp-proofing course that we’ve installed in over 60 years.

And last but not least,

My promise to you

As the Contracts Manager at Dampcoursing Ltd, I promise you that our team will:

  • Accurately identify your damp problem and its causes,
  • Advise you of the most effective solution,
  • Give you a quote for necessary works only,
  • Carry out the work to an extremely high standard, designed to last, and
  • Provide you with a full guarantee, to give you long-term peace of mind.

Whether you’re a homeowner or a trade professional, we’d be very pleased to help.

The first step: a no-commitment survey

If you’d like us to help with your damp problem, the first step is to arrange for one of our surveyors to visit.

Our surveyor will come to your property and do a thorough investigation. This will take from 30 minutes to an hour or so, depending on the nature of the problem.

They will then write up a full report of their findings. This usually takes a day or two to complete, and is emailed to you immediately.

The report

  • explains your damp problem and its causes,
  • includes a plan of the damp areas,
  • recommends the proposed treatment for fixing it, and
  • provides you with a quotation for doing the work.

This takes some time, and involves the expertise of our professional surveyors.

For this reason we do make a charge for the survey and report.

Together they cost £125.00 + VAT.

However this cost is fully refunded to you if you instruct us to go ahead with any works.

N.B. If you’re a trade client, please see the TRADE page for further details.

To be clear: having a survey done doesn’t commit you to anything else. If you don’t want to take it any further, that’s fine. And you’ll still have a detailed professional report giving you a full explanation of your problem and its remedies. This will be invaluable in helping you with any decisions you need to make.

Of course if you would like us to get rid of your damp problem, we’d be delighted to go ahead with the work, at a time that suits you.

Please don’t forget that here at Dampcoursing Ltd. we’re committed to offering you the very best possible service:

  • A hugely experienced professional team who understand damp-proofing better than anyone else – and who you can trust to know what they’re doing.
  • A full range of damp-proofing treatments, to give you the best solution for your problem.
  • High quality work that lasts for years, even after our guarantee period has ended.
  • A full guarantee with every job, so you know that you’re protected.
  • A helpful office team to contact whenever you need to.
