Common questions about crawl space dehumidifiers
Do I really need a dehumidifier in my crawl space?
Yes, if your crawl space has high humidity, it can lead to mold growth, wood rot, and pest infestation. A dehumidifier helps regulate moisture levels and protects your home from long-term damage.
How do I know if my crawl space is too humid?
Signs include a musty smell, condensation on ductwork or insulation, sagging floors, and visible mold. We can measure your crawl space humidity during a free inspection to confirm if a dehumidifier is needed.
What type of dehumidifier do you install?
We install professional-grade, energy-efficient crawl space dehumidifiers designed for long-term performance in enclosed environments. These are far more effective than portable units.
Will a dehumidifier reduce mold in the crawl space?
Yes. Mold requires moisture to thrive. A dehumidifier helps dry out the air, making the crawl space inhospitable to mold growth when combined with vapor barriers or encapsulation.
How much maintenance does a crawl space dehumidifier require?
Minimal. Most systems need filter checks or replacements every few months. Our team will guide you through maintenance steps and options for built-in drainage or monitoring systems.
Do I need to encapsulate my crawl space before adding a dehumidifier?
Encapsulation isn’t required, but it significantly improves the effectiveness of the dehumidifier by sealing out ground moisture. Many homeowners choose both for complete protection.

Understanding crawl space dehumidifiers
Crawl space dehumidifiers are specialized systems designed to control humidity levels in tight, enclosed areas beneath your home. Unlike standard room dehumidifiers, these units are built for long-term use in low-clearance, high-moisture environments.
When air becomes too humid in a crawl space, it creates the perfect conditions for mold, mildew, dust mites, and even wood rot. Over time, this moisture doesn’t just stay below your home, it rises, affecting indoor air quality and increasing the load on your HVAC system.
A professionally installed crawl space dehumidifier works with encapsulation and vapor barrier systems to maintain a dry, balanced environment. This three-part defense helps:
- prevent fungal growth and allergens
- protect your home’s structure from moisture damage
- improve your family’s respiratory health
- increase the longevity of your flooring and insulation
Michaelis only installs high-capacity, energy-efficient dehumidifiers that are built to last and designed to operate quietly and consistently, delivering performance you can count on.
Health risks of high humidity in crawl spaces
Crawl spaces might be out of sight, but when humidity builds up underneath your home, the consequences are anything but invisible. In Indianapolis and surrounding counties, where fluctuating weather can cause condensation, poor ventilation, and water intrusion, excess moisture becomes a serious health hazard, especially if left unchecked.

Why professional crawl space dehumidifier installation matters
While you can purchase a dehumidifier at your local hardware store, crawl spaces require more than a plug-and-play solution. Moisture problems beneath your home are often complex—and without the right installation strategy, you could be wasting energy without solving the core issue. Here’s why professional installation is essential:
1. it’s about more than just placing a unit
A dehumidifier won’t work properly if your crawl space isn’t sealed. That’s why our approach often starts with vapor barriers, insulation checks, and air sealing. Once moisture is contained, the dehumidifier can do its job efficiently, pulling water from the air without fighting a constant influx.
2. sizing and placement are everything
Too small, and it won’t reduce humidity. Too large, and you’ll waste energy and cause temperature imbalances. We calculate the exact size and placement based on your crawl space’s volume, condition, and airflow to ensure maximum performance.
3. integrated drainage prevents mold return
Our dehumidifiers include dedicated drainage lines to move water safely away from your foundation. Without this, you risk leaks, backflow, or puddling, all of which defeat the purpose. We also install condensate pumps or gravity drains depending on your home’s layout.
4. set-it-and-forget-it performance
Our systems come with smart humidistats and sealed ducting so you don’t need to crawl under your home to make adjustments. Once installed, it runs automatically, maintaining ideal moisture levels with little to no maintenance.
5. long-term savings and protection
A professionally installed crawl space dehumidifier can extend the life of your insulation, flooring, HVAC system, and structure. It also reduces energy consumption by making the air easier to heat and cool. That means fewer repairs and lower bills.
Don’t wait for the damage to spread
A humid crawl space is more than a nuisance, it’s a hidden threat to your home’s health, structure, and air quality. Left untreated, excess moisture can lead to mold, rot, pest infestations, and even foundation problems.
At Michaelis, we don’t settle for surface-level fixes. We inspect your crawl space thoroughly, diagnose the source of the problem, and install permanent dehumidification solutions that work in harmony with your home’s ventilation and waterproofing systems.
