Crawlspace Ventilation

Traditional crawlspaces typically have openings or vents in the walls that allow outside air to circulate below your living space. Usually, if insulation is installed, it’s in the form of fibreglass batts placed between the joists. The floor is most often soil or poured concrete, which is why you may need crawlspace ventilation services.

These types of crawl spaces develop a number of serious problems. During the summer, warm, moist air enters the crawl space and condenses on the cooler surfaces in the crawlspace. This steady influx of moisture helps mould to grow and makes wood rot. Damp wood will also attract insects like termites and carpenter ants which can cause additional damage. Fiberglass insulation easily absorbs moisture causing it to sag or fall out of place. Winter weather brings other problems: floors become cold and high heating bills get bigger. At any time of year, indoor air pollution can cause illnesses through airborne mold spores entering the home through cracks and gaps in the crawl space floor.

Today, building performance engineers recommend that vented crawlspaces be sealed or “encapsulated” to protect this area of the house from exterior temperature and humidity conditions. Crawl space encapsulation is the perfect solution for all the problems that occur in vented crawlspaces. No matter what size or condition, DELTA is ready with the training, tools and materials to seal any crawlspace. Contact us today for a free estimate on our crawlspace ventilation services.
