Tips for Maintaining a Crawl Space

Common areas with crawl space problems

Because most crawl spaces go largely unused, many homeowners aren’t aware of any problems lurking inside. Sure, they may peek in to pull out holiday decorations occasionally, but most folks never really spend any time down there. A dark and creepy crawl space often goes unnoticed. However, it’s not a good idea to assume everything is fine. Here are tips for maintaining a crawl space from your trusted foundation repair pros, ECP.

The conditions inside a typical crawl space make it ideal for fungus growth. This is especially true if your foundation hasn’t been properly waterproofed and you don’t regularly check your crawl space. As mold spreads, it can cause serious consequences for your family’s health. Also, it can cause problems for the structure and stability of your home.

Certain construction methods and materials can compromise a home’s crawl space that you may not be aware of – particularly in older homes. But you can prevent unnecessary property damage by avoiding each of the following:

OPEN VENTS:

Vented crawl spaces are very common here in Kansas City because building standards once required them. And while they may seem like a simple solution to prevent moisture buildup, they do just the opposite. Most crawl space vents in older homes are designed to stay open and circulate air, not dehumidify or eliminate water. During the summer, hot, humid air circulates through the cooler indoor spaces, coating surfaces with condensation. Precipitation may also cause problems when vents are left open. If left unchecked, all this moisture will create mold and mildew.

CHECK FOR INADEQUATE DRAINAGE:

Outdated plumbing can also be problematic for any crawl spaces, especially those that are underground. Standing pools of water invite insects to breed, and any flooding will damage your belongings and support structures.

If your plumbing system doesn’t have an effective drainage system, your pipes may leak or burst to relieve the water pressure. In a large crawl space, make sure there is a recessed drain on the floor that’s capable of draining large amounts of water quickly. It might also be a good idea to have your plumbing thoroughly inspected by a professional who can repair or replace any weak or damaged pipe sections – especially if you have an older home.

CONSIDER SPRAY FOAM INSULATION:

One of the most popular forms of insulation now comes in a high-pressure can. This expanding polyurethane foam quickly fills tight spaces. This makes it a popular choice for wall cavities, roofs, attics, and crawl spaces. It’s also one of the most energy-efficient types of insulation because it’s so effective at blocking heat, air, and water. However, the same properties that make spray foam insulation so effective could cause problems in your crawl space.

If you have wood walls or beams, moisture may get trapped between your foam and the wood. This causes these support structures to start rotting. And if your insulation is open-cell foam rather than closed-cell, it will absorb water vapor rather than trap it.

AVOID FIBERGLASS INSULATION:

Fiberglass is a terrible choice to insulate your crawl space! Fiberglass isn’t a protective barrier against moisture; if water collects on it, the insulation will soak it up like a sponge. Unless you inspect your insulation frequently or schedule regular energy audits, you may not realize it’s a problem until it’s too late. This insulation is designed for use in well-ventilated spaces with exhaust systems that send water vapor outdoors – NOT dark, damp crawl spaces.
