Four Mistakes Which Should Be Avoided While Repairing Crawl Spaces

Crawl spaces are complex and the state they are in can have a major impact on your home. Issues in crawl spaces are usually caused as a result of excessive moisture from the ground. Problems can range from mould accumulation and musty smell to excessive rot of the sub-floor structure, such as floor joists and wood beams. Regularly check for signs that indicate whether your crawl space needs repairs or not. Count on Paul's Basement Waterproofing for effective crawl space repair in Leamington.

Crawl Space Repair Mistakes


Hire a professional for crawl space repair as some of these mistakes can cost you thousands of dollars in re-repair. While repairing your crawl space:


1.      Avoid Adding More Ventilation


Adding more vents does not necessarily dry the moisture content in your crawl space. In humid weather, extra vents pull a lot more moisture into your crawl space. If you are using fibreglass insulation, it has the tendency to absorb water, which can damage the insulation over time. A humid environment will also make mould growth easier.


In cold weather, pipes and utilities (furnace, HVAC or hot water pipes) that need to be hot are cooled down as cold winter air enters the crawl space. The utilities will have to work harder to perform their daily work costing you additional energy.


More ventilation can cause rodents and pests to move in and cause damage that would need expensive structural repairs.


2.      Check for Drainage System


Crawl space usually has standing water after heavy rains. Standing water can cause damage, such as the increased risk growth of mould and mildew. Additionally, wooden structures can absorb this moisture and damage the structure of your home. A drainage system will help to keep your crawl space dry. For an effective drainage system:


·       Install a sump pump to control groundwater leakage

·       Install a discharge pipe that will be routed from your sump pump to the area outside the crawl space

·       Check for a perimeter drain, if major water problem exists

·       While repairing your crawl space, take special care to create a drainage system that takes into account the slope of the crawl space floor


3.      Install Vapour Barrier


Place vapour barriers across the ground, preventing ground moisture from entering the crawl space. The vapour barrier helps in moisture prevention and is made from plastic or foil sheet. The thickness of the sheet depends on the protection needed for your crawl space. Before installing a vapour barrier:


·       Remove any items that you have stored in the crawl space, for free access to the ground

·       Ensure the crawl space is dry and clean before covering the ground

·       Clean the surface for any mould before covering the ground with vapour barriers


4.      Avoid Installing Fiberglass Insulation


Fibreglass insulation is known to absorb moisture. Moisture from the soil can seep in and can be absorbed by fibreglass insulation. This will make the insulation heavy and it will start to fall out of place. It will also cause damage to the floor joints. Additionally, fibreglass insulation attracts insects, rodents and also has a higher probability for mould growth.
