Humid Crawl Space
Historically, it was believed that crawl spaces allowed for natural airflow. However, it has been discovered that vented crawl spaces are susceptible to moisture problems and mold growth and aren’t as energy efficient as once believed. Therefore, crawl space waterproofing, repair, and encapsulation have become necessary to overcome crawl space high humidity and moisture problems.

How do I know if my crawl space has high humidity?
You can detect high humidity in a crawl space using a hygrometer or relative humidity sensor. Signs of excess moisture may also include a damp or musty smell, visible condensation on surfaces, or a general feeling of dampness when you enter. If the relative humidity in the crawl spaces is above 60%, your crawl space likely has a humidity problem that needs attention.
How do I manage high humidity in my crawl space?
The best solution is to install a dehumidifier paired with an encapsulation. Without sealing off the crawl space the best you can first, the dehumidifier will have to work too hard, because there will be an ever-present source of fresh damp air flowing in from the ground, vents, and cracks in the foundation.
What is a crawl space dehumidifier?
A dehumidifier is a device that processes the air in a crawlspace, removing wet or humid air and replacing it with dry air. This reduces the risk of mold growth and wood rot, improving the home’s air quality, safety, and overall home’s value.
What type of dehumidifier does Dry Otter install?
Dry Otter currently installs AprilAire products. The Aprilaire E100 is commonly used. It’s energy-efficient, long-lasting, and manufactured in the U.S.
What is the warranty on a dehumidifier installed by Dry Otter?
How much maintenance does a dehumidifier need?
Dehumidifiers are self-contained units requiring minimal maintenance. Dry Otter recommends periodic maintenance to clean or replace the filter and test functionality through our annual maintenance program.
What are the benefits of a dehumidifier?
A dehumidifier will manage crawl space high humidity and moisture, which means less risk of mold, mildew, poor air quality, and wood rot. They filter allergens and provide dryer air for your HVAC system, helping with its efficiency as it allows for comfortable air for your home.

Vicki Gurley2025-09-25Trustindex verifies that the original source of the review is Google. After reading many great reviews, we used Dry Otter to remove mold and mildew from a newly purchased older home. Dry Otter then expertly encapsulated the crawlspace and installed a dehumidifier (Thanks Johnathan, Trey, and Desmond!!) and did the needed structual repairs. Great job!! The dehumidifier monitor now assures us that the crawlspace remains dry. THANK YOU, DRY OTTER! Rick Dunlap2025-09-24Trustindex verifies that the original source of the review is Google. The work done by Will and his crew was excellent. I can sit in my crawlspace with a sense of calm as it is so clean.

Kimberly Jones2025-09-17Trustindex verifies that the original source of the review is Google. After researching crawl space encapsulation and asking neighbors, I found Dry Otter. I contacted 4 companies and 2 didn’t even respond. Dry Otter came out and presented photos, info on their process & system and a quote on the spot. I appreciate their professionalism and responsiveness and the price was not only the better option but most importantly was a better material used and I like the fact they are independent family-owned. The team that did the work was Noah, Corey, Jam & Tristen. A group of very nice hard working young men. Noah was especially great and easy to work with. They called both days 20 minutes out, communicated during the process and explained everything in detail with instructions, etc. With our house being a new build only a year old, we wanted to make this important investment to protect the support beams and trusses for the long term. I’m looking forward to some energy saving as well. And, no critters or bugs will be especially nice too! I highly recommend Dry Otter! Joey Tirak2025-09-05Trustindex verifies that the original source of the review is Google. My crawlspace needed some attention had pretty high humidity and condensation on duct work. Decided to go with an encapsulation with foam board on walls. Dry otter was great to work with. Will and Josh were the installers and their communication and professionalism was outstanding. The crawl space looks great now and thet explained everything very well. They even checked back in a couple days after the install to make sure the humidity has dropped. highly recommend Dry Otter if you need a crawl space encapsulation
