crawl space
warning signs

A residential crawl space that isn't properly ventilated can attract fungus, decay, bugs, reptiles and rodents, as well as many other unwanted critters. They are attracted to the warm and moist conditions of the crawl space. This also means that your family is breathing in this moist, humid air that most likely contains mold spores. Mold spores can cause serious health problems, especially for people with chronic breathing conditions like asthma. Crawl space musty odors can also trigger allergies and severe respiratory infections.

An unventilated and moisture-filled crawl space can cause astronomical heating and cooling costs each month. A crawl space without ventilation can take away all the warmth in the summer and the cooling effect in winter with uncomfortable humidity levels. This is why Anchored Walls has professional crawl space installation crews for placing vapor barriers or encapsulation systems in your family's crawl space area.

Sagging floors

Oftentimes, homeowners ignore sagging floors and consider it a characteristic of owning an older home. Anchored Walls cannot stress enough how important it is to address all sagging floor issues, as soon as you notice that something isn't right.

Sagging or sloping floors in your home can be due to:

  • Inadequate or failing support beams
  • Inadequate foundation installation
  • Termite damage
  • Dry rot
  • Water seepage
  • Poor soil compaction
  • Improper landscape drainage
  • Excess moisture pooling around the foundation
  • Foundation cracks
  • Deteriorating wood support structures
  • Improperly installed floor joists
  • Improper installation of the floor itself

Understandably, it's not very simple to estimate the actual cost of our sagging floor repair services, but our foundation repair specialists will be able to give you an estimate once they evaluate the damage.

foundation cracks

Crawl space problems can sometimes be caused from foundation cracks or poorly installed foundations, especially in soil which contains clay materials. The dirt floor of a crawl space can become infiltrated with moisture, if the area hasn't been set up with a vapor barrier or encapsulation system. Serious moisture problems dcan cause foundation cracks, and while they may be small at first, they will eventually grow and allow water to seep in. As more water enters the crawl space, the damage can quickly begin to spiral out of control.

If you have utility components in your wet crawl space, corrosion may begin forming on the pipes, fittings, valves and any other exposed metal part. 

Please contact us for more details about foundation cracks, and their effect on your crawl space.

wood rot

Crawl spaces without proper ventilation and a dirt floor are susceptible to wood rot or dry rot. A dirt crawl space floor is part of nature, and unfortunately, it can be quickly affected by the outside weather conditions. Most of the time, moisture from the dirt (clay soil) can and will eventually cause rot to the sill plates, floor joists and girders underneath your house.

Wood rot is able to develop from a tiny organism, which is in relation to the fungi group. Fungi tend to grow and reproduce easily when there's the right amount of moisture, oxygen, humidity and "food."


Moisture in your crawl space can come from three sources: condensation from the air, water seepage through foundation walls and leaks from plumbing pipes. It's very rare for moisture to come from other sources.

High amounts of moisture in a crawl space leads to the destruction of wood by fungi, insects and termites. Crawl space moisture can also lead to the growth of mold and mildew. When you have mold in your crawl space, it means that you also have poor indoor air quality. Mold can cause respiratory problems for individuals with pre-existing breathing conditions, such as asthma.

Even "dry rot" requires high moisture levels in the area to occur. Sometimes, it's possible that you don't even notice the dry rot occurring in your crawl space. All of the floor joists will appear fine; however, rotting is taking place inside of the wood.

Water in crawl space

Standing water in your crawl space may lead to a wide assortment of structural problems and health concerns. Excess humidity in your crawl space will form due to the evaporation of stagnant water in your home's crawl space. This standing water may also act as a breeding ground for mold and mildew growth.
Water in crawl spaces can also cause water damage, warping or buckling of the sub-flooring. This typically occurs near the area where your home's floors and walls come together. Naturally, all of these crawl space moisture issues can potentially create unhealthy indoor air quality and living conditions for your family.
Standing water in your crawl space can compromise the structural integrity of your home over time. This may even make your home uninhabitable in the future.

moldy crawl space

Crawl spaces make for easy access to certain utility components and may even be used for storage. However, a crawl space that isn't properly ventilated will typically have a moisture problem. Over time, this moisture can act as a breeding ground for the development of dangerous mold.

Crawl space mold can become a severe and dangerous problem, because it creates unhealthy indoor air quality. Crawl space mold can also damage your home's structure and flooring. Mold feeds on organic materials, such as wood, and when it's damp, it creates the perfect environment for growth.

If you believe you have a moldy crawl space, know that it will eventually spread throughout your home. Research shows that nearly half of the air you breathe in your home comes from the space beneath it (your crawl space). This means that the air you breathe may be infiltrated with mold spores. Mold can cause headaches, fatigue, flu-like symptoms, fevers, breathing problems and a wide range of other health issues.
