Crawl Space Repair in San Francisco, San Jose, Fremont, CA

Eliminate crawl space moisture, mold, and structural problems

Why dry your crawl space?

Eliminate Odors

Damp, dark crawl spaces are the perfect breeding ground for foul odors. Pests, mold, and rotting structural components can leave your home smelling less like a clean haven for your family, and more like a hole in the ground. A dry, encapsulated crawl space will rid you of foul odors permanently.

Home Health

Over time, moisture in your crawl space can lead to sagging, buckling, and even collapsing floors as wooden components rot and concrete cracks. Crawl space repairs from Clean CrawlSpace Inc. ensure the long term health of your home from the bottom up, simultaneously shoring up your home's future market value.

Healthy Air Quality

With as much as half of the air in your home coming from the crawl space, it's essential that it's protected from moisture. If your crawl space is vented or unsealed, it's very likely that moisture has seeped into the crawl space, releasing mold, dust, and other indoor air contaminants into the rest of your home.

Increased Energy Efficiency

Open crawl space vents or poor crawl space insulation can allow heating or cooling to leak out of your floors during the winter and summer months. The resulting effect is an overworked HVAC system, which can raise your energy bill by a significant percentage. Proper insulation ensures you only use the energy you need, saving you hundreds each year.

Why is my crawl space wet?

There are a number of reasons you have a wet, damp, and musty crawl space. These include:

  • Plumbing failures
  • Open vents in the foundation
  • Saturated soil and poor drainage around the foundation
  • Poor grading around the foundation
  • Water leaks or seepage through foundation cracks
  • Ineffective drainage or sump pump systems

Why is my crawl space making me sick?

If you've noticed increased allergy or asthma flare-ups, chances are, your crawl space is the reason. Your crawl space provides a breeding ground for mold and mildew, indoor air pollutants that cause runny noses, sneezing, itching, headaches, fatigue, and a host of other symptoms. Air from your crawl space then travels up through the rest of your home, affecting indoor air quality.

How do I keep my crawl space healthy?

The best way to keep your crawl space healthy is to install a comprehensive crawl space waterproofing and encapsulation system. Our state-of-the-art crawl space solution comes with perimeter drainage, drainage matting, a sump pump, and a dehumidifier. This combination has proven effective at keeping homeowners' crawl spaces dry for a lifetime and has been used in thousands of homes throughout the United States and beyond.

How can I improve the air quality in my crawl space?

Poor indoor air quality in your crawl space is due to excess moisture, mold growth, and other contaminants. Air pollutants from your crawl space are transported to the rest of your home. To improve air quality in your crawl space and therefore your entire home, we recommend installing a complete crawl space encapsulation system. A proper encapsulation system will help maintain a stable humidity level in your crawl space and ensure that it stays clean.

Maintaining relative humidity levels is essential because it ensures that mold and mildew don't grow and affect your home's air quality.

Is it worth it to seal my crawl space?

There are so many benefits of sealing your crawl space that make it worth the cost. Sealing your crawl space helps prevent moisture from seeping into your crawl space, ultimately combating mold and mildew growth. Not only that but sealing your crawl space can save you money in heating and cooling costs. Plus, you won't have to worry about structural damage due to wood rot in your crawl space.

Can I seal my own crawl space?

Yes, you can seal your own crawl space. However, there are a lot of risks that come with DIYing your crawl space encapsulation, including the following:

  • You miss out on warranties, like our 25-year transferable warranty
  • Store-bought crawl space products may not last more than a few years
  • A lot of store-bought crawl space products won't prevent moisture and mold growth
  • You don't get an inspection to ensure your system functions properly

When it comes to crawl space sealing and encapsulation, you should skip the hassle that comes with DIYing it. You can count on us to get the job done right the first time, saving you time, money, and stress.
