Checking Your Crawl Space

Checking Your Crawl Space

Crawl spaces might be the most neglected area of the home, but regular maintenance is vital for the overall health of your home- especially after a long, wet winter.

Excessive moisture can wreak havoc on your home. Here are some things to look for as you check off your “Spring Cleaning”:

Cracks and Holes

Wait for a sunny day and take a look around inside your crawl space. Can you see daylight? If so, you definitely need to seal your crawlspace. If the light can get it, critters and moisture, and eventually mold spores, can get in too.

The most common places to look for cracks:

  • the space where the wall meets the floor
  • cracks or joints in the floor
  • joints in the wall below the groundline

Don’t be fooled by a small crack – small rodents like mice can enter through an opening the size of a dime, and water can get through just about anywhere. Pooling water can undermine your foundation, leading to costly repairs down the road.


Ventilation is important, but if not done properly, it can increase the moisture in your crawl space and do more harm than good. Especially if you vent to the outside of your home, the air on the outside is often more humid than the air in your crawlspace. In the winter, this can mean drafty homes and frozen pipes. In the spring, the warm air outside your home cools and condenses in your crawlspace, resulting in soggy insulation, muddy floors, rusted ducts and mold. Look for pools of water near vents and check to ensure that all seals are intact.

If you notice excessive humidity or water in your crawlspace, its best you go ahead and check out your insulation as well.

Insulation material acts like a sponge, soaking in the water and then holding it in place – allowing mold and mildew to build up and wear down organic materials, like your floor joists (eek!).

Don’t wait to inspect your home. If you notice any broken seals or standing water in you crawl space, contact a professional as soon as possible. An Atticare technician can thoroughly inspect your crawlspace and explain the best course of action. From a simple cleaning to a full encapsulation with a vapor barrier, our techs have the skills and experience to get the job done right.
