What Exactly Is Crawl Space Cleaning?

As previously stated, the crawl space is a space beneath the home and between the bottom of the house and the ground. Plumbing, gas hookups, ventilation, and electrical components are all located beneath. The goal is for you to be able to access them. Keeping your crawl space clean will help your home smell better and may increase the value of your home.

Why Clean the Crawl Space?

Health Reasons

If you have mold growing in your ductwork, it might damage the air that your family breaths in. If bugs or rodents have established nests, the air quality in your home will suffer.

Prepare for Inspections

If mold is discovered during a house inspection, the inspector will make a note of it. This is related to safety because it might influence the support beams and the health of the residents.

Increase Home Value

A clean crawl space can increase the value of your home if you are looking to sell. Be sure to address any issues that an inspector notes.

Typical Problems in Crawl Spaces

Rats and other animals will build nests in this space.

Mold and fungus grow in the dampness, polluting the air that the family breathes in the home.

Damaged Vapor Barriers
These must be repaired because they prevent ground moisture and mold and fungus growth.

Look for broken pipes that may be leaking water into the crawl space.
