Why Properties in Grantham get Damp Problems

common damp problems in grantham

Grantham and the surrounding villages have properties of varying styles and ages. Grantham town itself has a mixture of new build and period properties which can get affected by the natural forces of time. Older properties tend to experience damp issues due to moisture buildup over the years. In the surrounding villages, these properties tend to be much older and can include cottages, barn and country manors which all typically experience damp and timber issues due to age. We are experts in fixing damp issues in very old buildings so feel free to get in touch if you need more information.

Black mould, crumbling plaster, condensation and warped timpers are the most common signs of damp.

There are various key ways you can prevent damp in your home or property. Firstly, by keeping on top of outdoor maintenance, this involves checking the roof regularly for any damage, keeping gutters clear and generally checking the exterior of the property to ensure there is no crumbling or visible damage. Keeping your home well ventilated and warm will also help to prevent damp developing within your home. 

There are three different types of damp and each have completely different traits that require different types of treatment. These are condensation, rising damp and penetrating damp. 

It is advised not to start decorating your home for around 12 months after you have had any damp-proofing treatment. Although, once visible signs of damp have disappeared completely you can use a water-permeable emulsion paint on the affected areas (this usually takes between 1 – 2 months). 

Being smart about heating can help to prevent damp, as long as there aren’t any previous damp issues already in the property.
