Exterior Issues Can Cause Damp Internally
Exterior Issues Can Cause Damp Internally:
Dh Damp Proofing & Plastering have been to numerous properties in London & Berkshire were people are unaware that exterior issues can cause damp internally.
Being aware of the grounds surrounding your property can save you the hassle and not to mention money. By identifying a potential hazard, you can stop the interior of your property succumbing to a damp problem making it a more enjoyable environment to live in.
So now you’re probably thinking what is it you should look for on the exterior.
Firstly, make yourself familiar with your damp proof course level, you should be able to identify this quite simply it is typically on the second or third brick course. Then assess the area around the property and check for foliage, trees or newly installed driveways and patios. Check that foliage is away from the walls of the property as the moisture collected by the foliage can breach the damp proof course and the moisture can ingress into the property and cause damp on the internal walls.
Newly installed driveways and patios should never be installed at a higher level than your damp proof course, and should not be at an angle that slopes inwards towards the property. Again, this can cause a breach to the damp proof course and moisture can ingress and cause damp internally.
Trees that are too close to the property can also cause moisture to make its way inside because the roots can penetrate the foundations and cause cracks were moisture can then ingress. Trees can also suck all the moisture out of the ground making the earth dry leading to movement and subsidence.
Chimney stacks that are damaged can allow moisture to ingress down the chimney breast causing damp on the interior. We are not suggesting you get onto your roof to check but maybe having a look with binoculars instead to check for any crumbling bricks, missing mortar or damaged capping pots.
Damaged roofs are another thing that can cause problems on the interior. Missing slates, shifted slates or any damage that allows moisture to ingress should be addressed before the problem spreads to an internal damp issue.
You should check gutters and down pipes for any blocking or damage. These are designed and are there to keep moisture away from the property and any damage to this can cause moisture to flow directly against the exterior walls leading to penetrative damp internally.
Check the walls of the property for any missing mortar or crumbling bricks because damage to these can also lead to moisture ingress into the exterior of the property.
Windows and doors should be fitted correctly with all seals in place and no gaps around them which will allow moisture to make its way inside.
This list is not exhaustive, just bear in mind that exterior issues can cause damp internally.
