Moisture In Crawl Space Under House: All You Need To Know

moisture-in-crawl-space-under-house

Under the floor boards of your home isn’t just dirt, spiders and building foundations, but most likely, a ‘crawl space’ – a basement that isn’t big enough to stand up in, hence the name.

A crawl space normally isn’t suitable for storage or proper access, as it’s dark, dingy and often moist to the touch.

However, if there is moisture in a crawl space under the house, this can easily encourage damp to seep through into your floorboards. Why is it bad to have damp floorboards, and how can it be avoided? All will be revealed in the following article…

Why Is Damp An Issue?

Damp can cause deterioration of your floor structure and health issues for those in your home

When damp settles into a surface, it can take a long time to dry it out, and often requires costly repair to either entirely remove the affected area, or to reconstruct it back to its original structure.

When damp settles into flooring, it’s more likely that the entire flooring will need replacing than it will be that a repair can be carried out. This doesn’t come cheap!

Damp can also become a festering ground for mould, which flourishes in cold and wet environments. Mould in the home has an impact on the air quality within. This can have drastic negative consequences for the health of the residents within the property, as airborne allergens and irritants are released.

Surfaces that are damp-ridden, or have mould growing within, or on them, suffer substantial structural damage as they disintegrate. With floorboards, of course, this renders them not safe for you to walk on, but also, they can easily become foodstuffs for unwanted pests, such as rats, mice and termites.

Unlike more traditional insulation solutions, such as fibreglass panels and blown-in cellulose, spray foam insulation will not break down or degrade over time. Its chemical make-up ensures that it will never become food for pests, as it creates a barrier that prevents them from entering

Crawl Spaces Easily Become Wet. How Can This Be Avoided?

Spray foam insulation protects against damp in floorboards

The only way to entirely protect against moisture entering through the home is to seal off any areas where the moisture is able to transfer through to the interior of the property. This is known as ‘thermal bridging’, and by blocking the bridge, the area inside remains resolutely dry and warm.

This multi-purpose product can be either injected into crawl spaces, or sprayed directly into them. An industrial foam, the chemical mixture is 100% water-blown, and develops and spreads up to one hundred times its original size as it enters the air.

It adheres onto any surface, and is completely water and air tight, sealing off the interior of your home from the elements outside.

Spray foam insulation is primarily used as an insulation product to keep properties warm, and increase their thermal capabilities, but as a water-tight barrier, also keeps the sealed areas dry. Even the most residual vapour within the air is unable to pass through.

Unlike more traditional insulation solutions, such as fibreglass panels and blown-in cellulose, spray foam insulation will not break down or degrade over time. Its chemical make-up ensures that it will never become food for pests, as it creates a barrier that prevents them from entering.

The lack of mould growth will enhance the interior’s air quality greatly – which will be a noticeable benefit to anyone with a condition or illness aggravated by airborne pollutants.

How Is Spray Foam Insulation Installed?

Only expert installers can install spray foam insulation

Spray foam insulation is a chemical product, and so should only be fitted by accredited and properly qualified technicians. In the UK, the only company with specialist technicians who are certified by the British Board of Agrement (BBA) are us here at Home Logic.

Based in Southampton, but with teams of qualified technicians throughout the country, we are the most reputable installers of spray foam insulation.

The foam is applied using specialist equipment to mix it in equal portions with water, and to spray it onto, or inject it into, the relevant area. It is important, therefore, that only expert tradespeople apply it; in order to ensure it is done so correctly and safely.
