Damp Causes

The predominant problems arising with damp in older houses is penetrating damp, property faults and condensation. These are caused by a lack of maintenance or problems at ground level.Stepped foundations and concrete plinth exposed during pentrating damp problem

Also where the property has been modernised and double glazing added and no modern extraction has been installed. In the cooking or the bathroom areas the property’s humidity levels rise this becomes trapped in the house. Rising damp is rarely found because most property's still have an original dpc. Made from flint or a sand, ash and bitumen mix and in some case engineering bricks.

Cavity Wall Clearance

This penetrating damp fault can be removed by cavity wall cleaning.

Damp Proof Courses

New Dpc fitted during cavity wall clean out to stop any future rising damp problemsDamp proof courses were not regularly installed in any building construction method until the introduction of the Public Health Act in 1875. Three years later the Building Act of 1878 provided more detail on the types of constructions and the regulation of their construction.

They were regularly installed after this so by the time of the great Victorian building boom of 1880 they had become commonly installed. Rising damp would normally only affect a property if a small part had been broken during some other building works at that level.

Other Damp Proofing Companies

Many damp proofing companies just treat it all as rising damp with cement based products. Trying to just block the damp out and insisting you Hydroscopic salt stain caused by internal condensation and not rising damp or penetrating dampneed another DPC which will have to be chemically injected.

This method has proven to be the wrong long term approach and is showing up as failed crumbling pink gypsum plasterwork. It will have a high salt content due to humidity problems in old houses. This will appear within 2 – 25 years of this using this method of cement and gypsum plaster based renders in old houses.

This stain looks like rising and penetrating damp and appears to show Dpc failure but it’s not the humidity is causing it.

So as the work is guaranteed for Dpc failure only you will have to pay again to have it plastered to stop the hygroscopic salts constantly absorbing moisture from the atmosphere and making your wall look a mess.


Damp Survey

Click to our survey pageTo measure these effects damp companies use damp meters little yellow electronic devices with two little prongs for measuring damp.

The problem with these meters is that they measure all damp rising damp, penetrating damp, condensation and hygroscopic salts they don’t differentiate between them. So when it bleeps really loud or goes really red only an experienced surveyor can Interpret its readings and diagnose the property fault behind that reading.

These meters are useful in detecting the area the damp is coming from and at what level. And how its spreading in your property so a good surveyor will use the device as a guide because the device isn’t telling you what damp you have or why you have it.

That’s why you need some who works with Victorian and Edwardian houses because they are enthusiastic and passionate about the work they do. And the way that it should be carried out to preserve these period properties and their common faults.
