The days are getting shorter, the leaves are falling from the trees and there’s a noticeable chill in the air. That must mean it’s Autumn! It also means it’s time to start thinking about ways to prevent damp and condensation in your property.
The most common cause of damp in a property is the build-up of condensation. It should be made clear to your tenants that it is their responsibility to prevent condensation in the property. Once you have installed extractor fans in bathrooms, stress that tenants should switch these on every time they shower or take a bath. It might be worth investing in an extractor fan that switches on automatically in time with the bathroom light. That way, you won’t have to rely on your tenants remembering to do so. Extractor fans should also be fitted in the kitchen above the hob. Boiling water causes lots of steam to be produced, which will settle on the walls and windows if not removed.
Advise your tenants to open their windows regularly, especially in the kitchen and bathroom. During the colder months, they may be reluctant to do so, but windows need only be open for ten minutes a day for a noticeable difference in the levels of condensation build-up. Remind them that they need to close and lock all of their windows before leaving their house each day.
Tell your tenants not to put wet clothing on radiators. The water vapour mixing with the hot air will rise and settle on walls and windows. You may wish to fit a clothes line to encourage your tenants to dry their clothes outside.
Rising damp occurs when groundwater seeps through the bricks and mortar of a building because its damp course has failed. It is your responsibility as a landlord to make the building watertight again by fitting a new damp course. The cost should not be passed on to your tenants. You should ask a professional for their advice; rising damp is often misdiagnosed and fitting a new damp course could end up being a needless expense.
Penetrating damp occurs when water enters a building via an external wall or the roof and settles inside. This will invariably be because of a fault within the building, such as holes in the roof, damaged gutters, or cracks in the external render. Again, it is your responsibility to ensure that these issues are remedied and that the house is fit for habitation. Fixing penetrating damp is usually a simple process. Make a note of anywhere that the damp appears and find that point on the exterior of your property. Around this area you should be able to quickly find the fault and fix it yourself with some simple DIY. For serious problems, consult an experienced surveyor. A check of the whole building may be required to ensure the damp has not become wet rot, which would be disastrous for the structural integrity of your property.
