Crawl Space Cleaning

Protect your home from pests, mold, and odors

The crawl space area is one of the most neglected areas of your house. As crawl space cleaning professionals, we often find crawl space areas in complete disarray. We discover insulation that has been pulled down and contaminated with rodent droppings, urine, food caches, nesting materials and even rodent corpses. Ducting is often chewed through and nested in. Vapor barriers are damaged, improperly set down or non-existent, and excessive moisture has led to mold and rotting wood. Vents are improperly installed or even blocked completely.

The problems are enormous, but nothing we can’t handle.

How a Dirty Crawl Space Can Seriously Affect Your Home

The first step to cleaning your crawl space is understanding why it is so important. Your crawl space affects your home in 5 huge ways. The first is air quality.

1. Poor Air Quality

A dirty, uninsulated, unsealed crawl space is a haven for all sorts of pests and allergens. Moisture in the crawl space allows mold and mildew to grow, and attracts insects and pests to your home. Approximately 40% of your home’s air comes up from your crawl space. Dirty crawl spaces allow germs, allergens, and mycotoxins to infiltrate your home air. This can increase allergies, worsen asthma symptoms, and depress the immune system.

2. High Energy Bills

A drafty crawl space that has not been insulated can allow a significant amount of heat to escape your home. Because so much of the air of your home is pulled up from the crawl space area, if your crawl space is cold, chances are the rest of your home will have a hard time keeping the temperatures up. Additionally, you’ll have cold floors, drafty rooms, and high energy bills — especially in very hot or very cold months of the year.

Homeowners that install crawl space insulation generally begin to experience 30-50% savings on their energy bills right away.

3. Damage To Home Subfloor

Excess or ongoing moisture in your crawl space area can severely damage the structure of your home. Moisture can cause wood rot in your load-bearing beams, and can also warp or allow mold to grow in the subflooring. The cost of replacing or repairing the subfloor or support beams can be enormous — crawl space cleaning will cost much, much less.

4. Pest Infestations

Pests are attracted to warm spaces that are infrequently visited and have access to food. This makes an uninsulated, unsealed crawl space the ideal home for many pests, such as mice, rats, squirrels, ants, roaches, spiders, and even hornets. These pests can destroy insulation, rip holes in vapor barriers, chew exposed wires, and lower your home air quality dramatically.
