Can I get Damp Proofing without removing plaster?

If you’ve found damp in your home, you might have noticed a white sediment deposited on the surface of the affected walls; this is salt.  Any damp that makes its way into a property carries with it a range of minerals (including salts) and deposits these in the surface of the wall as it evaporates.  This is a problem for two reasons:

  1. It leaves a permanent stain on the wall; and
  2. The salts which are deposited are hygroscopic, meaning that even when the source of the damp that deposited them has been cured, they will continue to attract moisture from the internal air of the property, leaving the wall appearing permanently damp.

Where these salts are present, the wall plasters must be replaced.  As part of their work, our technicians commonly remove salt contaminated wall plaster and replace it with specialist salt retardant plasters to prevent the problem reoccurring.

How much does damp proofing cost?

The cost of damp proofing will depend on the size and causes of your damp issues. The cost of our projects normally starts at around £1,500.00 plus VAT and can rise, depending on the amount of work required. We offer free surveys, so get in touch today for a bespoke quote, which will help you to understand the extent of work required.


How long does damp proofing take?

We always aim to complete damp work in the time specified by your Surveyor. It varies according to the size of the project; a small job could take as little as 2-5 days, a large project might take 3-4 weeks. Additionally, once a wall is plastered, drying time must be allowed to ensure that the work is as effective as it can be, and that the treatment lasts. In every job that we undertake, we will give you an approximate timeframe and ensure we work as effectively and as quickly as possible.

How does a chemical stop damp?

The chemical which our technicians use is injected in a continuous line near the base of a wall affected by rising damp. When the chemical cures, it acts as a waterproof barrier which prevents any additional water rising past it and into the interior of your home.

What pitfalls should I be aware of when looking for a damp contractor?

Whenever you’re embarking on a damp repair project, it’s important to get a clear idea of the associated costs and to formalise this in a contract, before instructing a contractor to proceed. The existence of a clear contract helps you to avoid any uncertainty about what work will be carried out and ultimately what you’ll be paying for. Avoid contractors who do not use contracts and only offer a brief description of what work they’ll be carring out. Often, this can be an indication of an inexperienced contractor.

At Allerton Damp, we always provide our customers with a quotation which itemises the work that will be carried out. A helpful floorplan is included which shows the area(s) in which work will take place.
