Should I Put a Dehumidifier in My Crawl Space?

Crawl spaces can contribute to various problems throughout your home, making moisture management essential.

In a previous article, we answered the question, “Do I need a sump pump in my crawl space?” In this article, we’re going to answer the question, “Should I put a dehumidifier in my crawl space?” The answer is quite simple, so we won’t waste your time. Let’s jump right in.

Should I Put a Dehumidifier in My Crawl Space?

If your crawl space has high humidity levels, a dehumidifier can be an excellent addition to your home. Crawl spaces are notorious for trapping moisture, leading to problems such as mold, mildew, and wood rot. Here are some reasons why a dehumidifier might be necessary:

Man installing dehumidifier in a crawl space.
  • Moisture Control: A dehumidifier helps maintain healthy humidity levels, reducing the risk of mold and mildew.
  • Improves Air Quality: By reducing humidity, a dehumidifier can improve the overall air quality in your home.
  • Protects Structural Integrity: Excessive moisture can weaken wooden beams and joists, compromising your home’s foundation.
  • Discourages Pests: Many pests are attracted to damp environments. By keeping your crawl space dry, you can create a less hospitable environment for unwanted critters.

For more information on crawl space moisture control, check out our guide on Crawl Space Encapsulation.

Had BAU take care of a chimney that was leaning away from my home, fix my front door which would jam at times of the year and relevel my floors. This was my second time working with BAU who installed screw jacks and leveled my floors several years ago. This time, Juan took a look at the problem areas, took measurements, made recommendations that fit my needs and budget and answered all my questions. Gonzalo and team came to work on my property. They worked quickly to install piers under the chimney and in the crawl space. They put tarp down to keep the house clean in the areas they needed access and cleaned up after themselves each day on the job. They answered my questions and throughly explained the problems and solutions they would implement to level the floor. Overall, I'm pleased with their work, being on time each day, and communication skills and would recommend.

BAU did a great job on my ADU that had a serious moisture problem that was causing the building to deteriorate. I couldn't remove the tile without replacing it all at a large expense so they did the whole job in a very cramped crawl space. The guys they sent out were great and finished with everything in one day!!!

Jonathan Falcone was great to work with. He visited a couple times and walk through multiple options of design to rectify the sloping issues of our house. He was attentive and took multiple calls to help with the review and planning process. I would highly recommend to work with Jonathan! Looking forward to the project kicking off and the sloping foundation to be fixed!

Foreman Andrew is incredible and a leader. We hired BAU to perform a whole house underpinning job from December 2022-March 2023. Our recently purchased 1950's home sat on expansive clay soil and had been settling for decades. The project was a big job and complicated by the winter rains that occurred throughout many days of the project. Andrew was extremely professional, knowledgeable about every aspect of the job and managed the entire project class and skill.He communicates very effectively and is transparent to assuage any concerns that we had on the project. He also shows up earlier than anyone, and works the entire day, rain or shine, in the mud and trenches with his team. This leadership was impressive. Since the completion of our project, he has remained available and came out to make some minor adjustments promptly and free of charge. Without any hesitation, I would entrust BAU to do my foundation work with the demand that Andrew lead the project. Thank you Andrew and your crew for a job well done.

Our house is 85 years old and has some cracking on the stucco, so I called for a free inspection to see if the problems were something we need to be concerned about. Daniel, our inspector, was prompt and friendly and explained everything he was doing and seeing as he took measurements and inspected the foundations. He said that while there are things we can do for earthquake retrofitting (and he did recommend a separate company for that if we wanted to do it) our problems were mostly cosmetic and nothing to worry about. He also took his measurements to be scanned in at his office and kept on file so that we can have him back out for another inspection in the future to compare, again, purely at our discretion. He was respectful, friendly, and straightforward and answered all of my questions. I'd definitely recommend them.

We recently had foundation work completed. The crew was on time every day and worked hard to keep a very dirty job and their traffic through the house to a minimum. The crew chief, Robert Busch, was amazing. Telling us what was planned for the day, any unforeseen problems, and giving us a recap of what was completed daily. We could not have had a better experience with his communication and hard work. Everyone was respectful and friendly. I also thought that the evaluation and estimate experience was positive. Jim communicated clearly and we never felt that work being suggested was unnecessary. He explained clearly and showed us pictures of what was going on under the house.Hope we never need them again, but would use them in a flash.

1. Call Center ***** – they took the call after 6:00 PM and were extremely professional. Guy on the phone (sorry I didn't write is name down), was so kind and emailed confirmation immediately. 2. Pre-Visit Confirmation ***** – Email, text and phone calls to confirm the time and prep me for the visit. Incredible. Nobody is doing this right these days and BAU absolutely has it nailed down. 3. Estimator ***** – I wish I could offer more than 5 stars. Joe Le Bel is the most professional tradesman I've met in a long time. Others are good too, but Joe is the gold standard. He sat with me to ask what I was concerned about and what was important to my family. Who does that???? Oh yeah, Joe did. So comforting. Joe was professional and respectful of our space. Was careful to be conscientious about where he placed his gear, tools and instruments. Super clean going under the house without tracking dirt and debris back into the house. (The inspectors from HomeGuard could definitely take notes on this!) Then, once Joe finished, he sat down with us and talked us through all the different aspects off his inspection. What an extremely positive interaction. I would 100% recommend BAU and Joe. Can't get any better than this. Thanks BAU for a great culture of excellence. Thanks Joe for being such a good human and professional!

I had Joe inspect the crawlspace of my home, and I couldn't be more satisfied with the experience. First off, he did the inspection for free, which is rare these days! Joe was professional, punctual, and thorough in his inspection, explaining everything he found in a way that was easy to understand. He took the time to ensure I knew what was going on beneath my home and didn't push any unnecessary services. I highly recommend him for anyone in need of an honest and detailed inspection. Definitely a 5-star experience!"

Brandon and his crew were wonderful to work with. We had pretty extensive movement in our foundation, and Brandon was knowledgeable and took the time to carefully explain all of our options and how each would look. He and his crew were communicative and professional. Our biggest fear was that our new kitchen granite counters would crack in the lifting, but Brandon and his crew were extremely mindful of the situation, taking extra care and nothing cracked. Thank you, Brandon!
