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.

Rob and crew from NW Crawl Space did full remediation for our crawl space and attic, after finding evidence of rodents (mice) in both areas. Removed old crawl space insulation & vapor barrier, replaced heat-ducts that were damaged, & vacuumed out attic insulation and debris. Sealed openings in both areas to prevent rodents from returning. Traps set, with rodent control plan. Highly recommended!

Northwest Crawl Space Services has been honest, professional, easy to work with, and has done excellent work on my home. I first approached the company looking for someone to reinsulate and clean out my mud room crawlspace-- it is an addition to the house and is open-air. Lior came by and noted that because NWCSS specializes in fiberglass insulation, they wouldn't be able to work on this part of my house, because it would require spray foam insulation to truly be rat and weather proofed. I really appreciated this up front honesty-- two previous contractors had given me bids to reinsulate with fiberglass, never mentioning the need for spray foam, and never saying that they wouldn't be able to do a proper job. I would have paid money to some other company for a shoddy, inappropriate "solution" if Lior had not filled me in. Lior even recommended some other companies to call that specialize in spray foam! After this helpful and informative experience, I knew right away when I discovered signs of rats in my main basement crawlspace that I wanted NWCSS to be the ones to work on the problem. Lior came by to check it out and did a very thorough inspection. His manner with clients is excellent-- I never felt like my questions were being dismissed. We set a date for a crew to come by to replace rat-infested insulation, remove the improperly installed vapor barrier, clean out debris, and reinstall vapor barrier to industry standards. The crew, Patrick and Chandler, were friendly, polite, and happy to answer questions. Savannah in the office has also been very friendly and quick to answer my questions regarding logistics and payment. Overall, my experience was excellent and I will re-hire NWCSS when it comes time to reinsulate and clean out my attic crawlspace.

Matan gave us a fair estimate for the crawl space re-insulation and screening, and the work was done promptly. I was pleasantly surprised when the final bill came in about 15% UNDER the estimate. It’s nice to deal with a company which has the integrity to pass those savings on.

Northwest Crawl Space is a trustful company to work with. They helped me install the French drain, replace the insulation and vapor barrier. Matan and his stuff did a great job. They will carefully protect your home when performing the job, clean the waste after the work is done, and come back to inspect if the work is good.

We had Northwest crawlspace come out to inspect our crawlspace and they identify a lot of standing water as well as rodent activity in the insulation. As a result, we needed a full clean out of our crawlspace and new insulation, vapor barrier, drain and sump pump. The crew was professional, friendly and fast. The work was extremely well done, we recently had them come out to check everything and the technician confirmed it was one of the best installs he had seen. I would highly recommend this company to anyone.

I had Northwest Crawl Space Services remove all my rodent infested insulation and vapor barrier. They cleaned & disinfected my crawl and installed all new insulation and a sealed vapor barrier. The workers were very diligent and and skilled in their methods. I was given a quote up front and feel that I received a quality job that was worth every penny. I am beyond pleased with the company and would highly recommend them to everyone.

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.
