Crawl Space Dehumidifier Installation Prices & Reviews

Crawl Space Dehumidifiers

You probably have crawl space moisture if you’ve noticed a damp feeling in the house, moldy closets, or musty odors. Due to the stack effect, up to half of the air in your house can come into the house from the crawl space.

Stack Effect – aka the chimney effect – as warm air rises, it pulls the air upward. It creates a suction, whereby sucking air from the lower extremities of the house, including the crawl space, floor vents, doors, windows, or other minor openings.

Once you have high moisture, a crawl space dehumidifier might be necessary. We have warm, humid summers in Virginia and North Carolina with high outside humidity, making for wet crawl spaces and fertile grounds for mold growth. Long-Term Value: Structural Preservation and Savings. A professionally installed dehumidifier does more than prevent mold—it acts as an insurance policy for your home’s core structure. By maintaining the humidity below the critical threshold of 55%, the unit prevents wood rot and fungal decay that damage support beams and joists. This structural stability, combined with up to 15-20% HVAC energy savings (by reducing moisture load on your AC), makes the installation a wise, long-term investment.

Two Ways to Install a Crawl Space Dehumidifier: Contractor or DIY

Contractor: Professional Vs. Handyman

To install a dehumidifier properly, you need to make over 20+ distinctions. Our recommendation is ALWAYS to trust the Experts. Get it done right the first time.

If you hire a handyman vs. hiring a professional contractor, you’re risking an incomplete and ineffective result that is important to achieve the first time. You don’t want to assume everything is working when it’s not because most people don’t regularly check their crawl spaces.

Diy: Consider All the Costs, Tools, and Skills Required

The Hidden Cost of DIY: Improper Sizing and Failure. The cost of the unit ($1,000–$2,000+) is only the start. The critical factor is sizing the unit correctly for your crawl space’s cubic footage and moisture load. An undersized unit runs constantly, wastes energy, and fails to solve the problem. When you hire BAY, our experts perform a full load calculation to ensure the right capacity (measured in Pints Per Day (PPD)) is installed the first time, preventing expensive rework and guaranteeing mold control. Keep this in mind when considering your options.

Best Crawl Space Dehumidifier Brands and Prices:

Aprilaire Crawl Space Dehumidifier Price

Why We Choose Professional-Grade Units (e.g., Aprilaire): We use high-capacity, Energy Star-certified commercial-grade dehumidifiers built specifically for the crawl space environment (e.g., Aprilaire). These units are selected not just for their leading 5-year warranty but for features critical to long-term performance: Low-Temperature Operation (Effective at 40°F), Self-Draining Capacity (no buckets to empty), and Integrated MERV 8 Filtration for superior air quality. We install units with the best Pint Per Day (PPD) rating relative to energy consumption.

Aprilaire Reviews

We have installed over 1,000 Aprilaire dehumidifiers, and our results are consistent. Maybe 1/50 units have minor errors but are easily troubleshooted by our expert technicians. They are not as quickly set up as the Santa Fe units but are much more dynamic, with more capabilities and better repair options.

Aprilaire crawl space dehumidifiers are what we recommend and what we install. The 5-Year Evergreen Warranty on the Aprilaire units is the best in the industry.

Aprilaire gets 5 of 5 Stars from BAY Crawl Space & Foundation Repair!

Santa Fe Crawl Space Dehumidifier Price

The price for a Santa Fe Compact 2 dehumidifier (most popular) sells for $1,118.99 at Sylvane.com.

The Santa Fe Advance90 dehumidifier (2 fans) costs $1379.99 on the Sylvania website, while the Advance100 costs $1798.99.

A Santa Fe Classic dehumidifier (basement) costs $1,699.99. This is the best basement dehumidifier available for large basements. It has a large capacity to control moisture in your wet basement. Because it is a standup unit, it is not applicable for crawl spaces because of its 36” height.

Santa Fe Reviews

We have also installed over 1,000 Santa Fe-brand crawl space dehumidifiers. We don’t have many problems with these units, but we switched to Aprilaire because of its superior technology and warranty. The warranty for the Santa Fe compact dehumidifier (the most common unit) is only one year on parts and labor, with a limited five-year warranty. This warranty isn’t great.

The best thing about the Santa Fe crawl space dehumidifier is its super-easy operation. The controls are simple. Set the dehumidifier to ‘Fan Auto’ and change the dial to ‘Normal / Dry,’ and your crawl space should dry up IF it is properly sealed.

Assessing your Crawl Space for a Dehumidifier

If you suspect your crawl space might have moisture issues, consulting an expert is a great idea. We’re happy to give you honest, unbiased options for controlling your crawl space moisture, with or without a dehumidifier. Our Expert Advisors will guide you on the best options for your home.

Our Reviews Reflect Our Commitment to Taking Great Care of Our Customers

  • “After shopping companies and getting several bids on the same project, we chose Bay Crawl because of their reputation and price. They had our whole house leveled and stabilized in two days. Left our property cleaner than they found it with a smile on their face. Do NOT plan your next project without getting an estimate from Bay Crawl.”

    – Ryan Simpson

  • “Our experience with Bay was outstanding. From first contact everything was smooth and made as easy as possible for us. We were kept informed every step of the process via email, phone, and text. The work was top-notch. The cost was extremely reasonable. We were impressed that Bay did not try to sell services that weren’t required.”

    – Teresa Lackey

  • “My experience was nothing but the best with Bay Crawl Space. The price was much more affordable than what another company quoted. Scheduling was easy and painless. They were professional and treated my home as if it was their own. They left me feeling very confident in my decision to go with Bay.”

    – Michael Turner

  • “It was an easy decision to choose Bay Crawl Space over the three other estimates I had gotten—not only was the price reasonable based on my research, but Jamie was the only sales advisor who described more than one option that I could choose. The scheduling was very smooth! I am confident that if I have any problems, I can call & they will resolve them.”

    – Diane Taylor

  • “Severe water damage to the structure. We thought we were in real trouble but after talking with them, we felt much better as we were assured that this was “Easy.” Our experience with Bay was better than we have had with any other contractor EVER. Upfront with what to expect, honest in their communications, and fair pricing.“

    – Mike O’Neill

  • “We had our crawlspace encapsulated by BAY three years ago at a fraction of the cost of JES’s estimate. The work was done on time and to exceptional standards. The office has been courteous, the workers arrived on time, and the work was accomplished as promised. BAY gets my highest recommendation.”

    – Bob Essman

  • “I am delighted with the crawl space encapsulation completed by Bay Crawl Space & Foundation Repair. What I particularly appreciate about BAY is their attention to detail & commitment to excellence. They were punctual and very much worth the value. I highly recommend Bay Crawl Space to anyone looking for excellent service & an affordable product.”

    – Leslie Ballard

  • “I’m not one to take home repairs lightly so I try and do my research. I got over 4 estimates to have my crawl space encapsulated and some repair work done. BAY beat the others prices by over 10k. Oh and they actually did more work that what the others quoted us to do. They also do quality work. So value for money, BAY is the company to go with.”

    – Benjamin Alexander

  • “I had an independent civil engineer out to inspect prior to the BAY visit. I was afraid I might be oversold on repairs I didn’t need. This was not the case. BAY made the same observations and gave same explanations or better. Great job BAY on hiring honest and competent assessors. Very professional, will work with you again!”

    – Zachary Frey

  • “I’m super pleased with the work Bay did us, it made a difference almost immediately. Our service advisor, Beau, did an excellent job of identifying the issues in our crawl and offering reasonably priced solutions. The team they sent out to do the work was awesome. They were friendly, knowledgeable, and efficient!”

    – David Green

  • Bay Crawl is by far the number 1 company for all of your crawl space and foundation needs. They are fairly priced. When coupled with the amazing service you receive, its a value that’s unbeatable. Every employee I interacted with was professional, polite, knowledgable, and hard working. You will not deal with a better run company than Bay Crawl.
