Common Reasons for Rain or Ground Water in Your Crawl Space

Poor Drainage

Inadequate grading around the perimeter of your home can lead to water pooling near the foundation, increasing the risk of water seepage into the crawl space.

Leaking Gutters or Downspouts

Damaged or clogged gutters and downspouts can cause rainwater to overflow and collect near the foundation, ultimately finding its way into the crawl space.

Hydrostatic Pressure

During heavy rainfall or periods of high groundwater levels, hydrostatic pressure can build up around the foundation, forcing water through cracks or gaps and into the crawl space.

High Water Table

In areas with a high water table, the natural level of groundwater may rise close to or above the level of the crawl space, increasing the likelihood of water entering the space through the ground or foundation walls.

The Hazards of Standing Water in Your Crawl Space

Mold Growth

Standing water creates a damp environment ideal for mold growth. Mold not only damages building materials but also releases spores that can cause respiratory issues and allergies.

Structural Damage

Prolonged exposure to moisture weakens wooden supports and can lead to structural damage in your home's foundation, floors, and walls.

Wood-Destroying Organism Infestation

Standing water in your crawl space attracts wood-destroying organisms such as termites, carpenter ants, and wood-boring beetles, which thrive in moist environments. These pests can cause significant structural damage to your home by feeding on wooden components.

Odors and Indoor Air Quality

Stagnant water emits foul odors and contributes to poor indoor air quality, leading to discomfort and potential health problems for occupants.

Electrical Hazards

If water comes into contact with electrical wiring or appliances in the crawl space, it poses a risk of electrical shock and fire.

Increased Energy Costs

Moisture in the crawl space can lead to higher humidity levels throughout your home, making it more challenging and expensive to regulate indoor temperatures.

We recently hired Northwest Crawl Space Services to perform a complete remediation of our crawl space which had a rodent infestation. Lior initially came out and did a thorough assessment and explanation of what work needed to be done. He was very detailed in explaining all work that they would do and the subsequent follow up visits and warranty that was included in the price. The following week Robert and his crew came out to perform the work. They were punctual, courteous and extremely professional in every way. They took caution and care to make sure that the inside of our house was properly masked off and protected as they removed the entirety of the contaminated crawl space insulation etc. Robert provided me with detailed pictures of the finished work and as well as pictures of a couple water pipes that had very small leaks, which I greatly appreciated. As promised, Lior came back out two weeks later to inspect all work and make sure that there were no problems. I highly recommend Northwest Crawl Space Services!

Lior and his team were fantastic. They were cheaper than the big name companies and didn't try to upsell me to repairs that didn't need to be done. They took care of the problem quickly and were great with communication and photos of the project as it was being completed. They owner even did a follow up the next day to make sure the job was done correctly. I had a list of questions when the job was done and he already had them all addressed with pictures and videos of everything. They are locally owned and operated which is very important to me. Would highly recommend

We had a sump pump fail and ended up with a crawlspace that had at least two feet of standing water. Matan of Northwest Crawlspace Services came out to inspect. After examination, he carefully explained our problem and his proposed solution using easy-to-understand, non-technical language, and then gave us a firm price quote. His professionalism made us feel very much at ease and gave us assurance that we were in good hands. The very next day, a worker was sent to pump the water out of the crawlspace so that work could begin. After the water was gone, a crew of three workers was dispatched to begin the work. Before doing anything, they took great care to install plastic sheeting to protect all of the walls and floors leading up to the crawl space access door. The crew worked diligently throughout the day and completed most of the work. Afterwards, they thoroughly cleaned up, leaving little sign that they had even been there. The following day, they came back to finish the work and replace some duct work that had been damaged by the flooding. A little later, a separate person (presumably a supervisor) came by to inspect the job. We are thoroughly satisfied by the work of Northwest Crawlspace Services and would highly recommend them to other homeowners.

Frequently asked questions

Is a crawl space drainage system necessary if there's only a small amount of water present?

Even small amounts of water in the crawl space can lead to moisture issues, mold growth, and structural damage over time. Installing a drainage system can help prevent these problems and maintain a dry and healthy crawl space environment. It’s important to address any water intrusion promptly to avoid potential long-term consequences.

Several factors could contribute to this sudden occurrence. It’s possible that changes in weather patterns, such as heavy rainfall or melting snow, have led to increased water infiltration. Additionally, shifts in the water table level, which can vary from year to year, may result in water entering your crawl space. Aging drainage systems or shifts in the soil around your home’s foundation could also play a role.

The installation time for crawl space drainage systems varies based on factors like the size of the crawl space and the complexity of the drainage system. For an average-sized house, installation usually takes between 1 to 2 days. Our team can provide a more precise estimate after evaluating your specific requirements.

Signs such as musty odors, visible moisture, or water damage in the crawl space indicate a need for drainage solutions. Regular inspections can also help identify potential issues early.

While DIY installation may seem feasible, it’s best to hire a professional for optimal results. Our team has the expertise and equipment to ensure proper installation and long-term effectiveness of the drainage system.

Crawl space drainage is crucial for preventing water accumulation, which can lead to mold growth, structural damage, and other costly issues in your home.
