Landlord Clinic tips and tricks No 9


Condensation is one of the most frequently reported issues we have in old properties. Most of the time tenants refer to it as damp, which in many of the cases is just not true. In Castledene we refer to it as lifestyle damp as much if not all of it is down to the way that the tenant choses to live.

A lot of the old houses that we rent out were built in the early 1900s and were not built to accommodate UPVC and modern windows. The old windows were drafty and had air bricks allowing ventilation and air flow throughout the house.

Moving forward about 50-100 years the houses are now sealed tight so ventilation is poor. When you have the heating blasting the hot air cannot escape so when the tenants use water, showers, washing machine or even breathing (although you can’t stop that) it will form water droplets in the air which collect on the windows or colder spots in the house

This can easily be fixed by ventilating the property better, trickle vents in the windows, open windows when showers, baths are on, or by keeping the heating at a reasonable temperature.

A lot of the houses have been built in such a way that even with all the measures stated, they will still get some condensation. It’s up to landlords to educate the tenant and come up with joint solutions. Don’t blame the tenant and the tenant shouldn’t blame the landlord. Find a win win for both parties
