What types of damp treatment do we offer?

Penetrating damp (or water ingress), is a type of damp problem that is the result of moisture or rainwater successfully penetrating through to the internal wall from outside the property. One of the unique things about penetrating damp is that, unlike rising damp, it can occur at any level of the building, including ceilings, floors and walls, and usually gets visibly worse at certain times, like during wet weather.

There are several common issues that are known to frequently cause penetrating damp:

  • Broken water pipes
  • Leaky roofs
  • Failed water management systems
  • Blocked or damaged guttering
  • Badly maintained brickwork
  • Poorly installed cavity wall insulation

What are the signs of penetrating damp?

There are several symptoms that can indicate a problem with penetrating damp. These can include:

  • Damaged or peeling plaster
  • A damp or musty smell
  • Localised damp patches
  • Watermarks that appear when it rains
  • The appearance of black mould
  • Damage to exterior stone or brickwork

How do I identify the source of penetrating damp?

First, you need to try and identify what is causing the penetrating damp. Look out for cracks in the external wall or missing pieces of mortar where water may be getting in, as sometimes old bricks can become porous, thus allowing water to penetrate your home.

One good tip is that if the penetrating damp is occurring at the same height as your guttering, you should examine your downpipes and gutters for cracks or leaks. Other places to inspect include your roof, the flashing, the pointing (this is the cement between the roof tiles) and the roof ridge.

You can also check to see if there are any cracks around the door frames which may need repairing and do the same around the window frames too. Lastly, penetrating damp can also occur because of leaking pipes, especially in the kitchen and the bathroom.

If you are struggling to identify the source of your damp problem, then our team can provide a professional damp survey to get to the root of the problem. Contact us today to arrange your property survey today!

What do I do once the source of penetrating damp has been fixed?

Once the source of the penetrating damp has been eliminated, a course of damp treatment can be applied. The type of treatment and repair work will depend on which area of your home was damaged as a result and can include undertaking building services such as repointing crumbling or missing mortar between bricks, resealing the damaged or defective area and undertaking treatment that effectively stops damp being ‘bridged’ from the outer skin to the inner skin of the property.

Our damp specialists are experienced in providing effective damp treatment to help prevent your damp problem from reappearing, as well as repair and refurbishment work to get your home back to its former glory!
