How To Deal With Rising Damp On Old Houses

Dampness can be triggered by several factors. Rising Damp can potentially be problematic on the masonry of walls and could cause health concerns in worst cases. Newer buildings aren’t likely to encounter such problems due to the installation of DPCs or damp proof courses. Old buildings and houses on the other hand, are more susceptible to the effects of Rising Damp. Let’s take a deeper look into what causes dampness in old houses and how to treat them.

First off, it’s quite necessary to understand the different types of old homes. Understanding the type of property will allow a homeowner to determine the type of fixes needed without causing any unnecessary damage and repairs. Here’s a list of the type of homes built before the 1940s:

Gregorian Homes – During the old times, particularly in the Gregorian era, homes were built without DPCs or damp proof course. On the other hand, Gregorian homes were built with good ventilation, which allowed the homes to keep humidity levels to a minimum.

Victorian Homes – Condensation is a common problem among Victorian homes due to the fact that they are primarily built with solid walls, which were cold and had large surfaces. Victorian homes also used a lot of timber, which meant the possibility of rot when Rising Damp manages to crawl up to vulnerable areas.

Late Victorian Homes – During the late Victorian era, the DPCs became a staple of construction. Cavity walls were introduced and greatly reduced dampness. The space in between the walls allowed for ventilation. Early forms of DPCs were used in late Victorian properties. However, the wear on Victorian homes today could have resulted in the filling of cavities, which could have bridged the air gap.

Edwardian Homes – By the time of the Edwardian era, Rising Damp has been a known occurrence. This has resulted to the addition of DPCs to almost every property. Slate, bitumen, and hessian DPCs were commonly used during the period. Damp only became a problem during the period if the DPCs failed to do as intended.

Understanding ThePrimary Causes Of Rising Damp In Old Properties

There are a couple of reasons for damp in old homes. It is necessary to isolate the cause of dampness first before proceeding to treatments. Here are the most likely causes of damp in old homes:

Condensation – This is probably the most common reason for damp in old homes. The temperature difference between the walls and air could cause condensation. However, it is fairly easy to detect condensation. Molds on the wall are telltale signs of condensation.

Interstitial Condensation – There is also another way for condensation to occur. Warm moist air can sometimes enter the structure of the house. When the air gets trapped, it condenses and creates the problems associated with dampness. This is why it is necessary for buildings to always have adequate ventilation.

Poor Ventilation – Air normally enters a building and into different structures. It is up to the building’s ventilation system to prevent any moist air from being retained inside and condense. This is quite an important feature in homes nowadays. However, poor ventilation can cause a number of problems including dampness.

Penetrating Damp – Rain can pour a lot of water onto homes and it can be problematic. Issues with structure, wrongly placed gutter systems, and or cracks could contribute to penetrating damp.
