High Levels of Moisture in the Crawl Space and the Problems it Causes in Annapolis, MD and Nearby Areas


Relative Humidity levels at or above 60% create the perfect environment for mold and dust mites to occur. These pests release mold spores and droppings into the air you breathe, making it harmful and allergenic. Other hazards that could come from a damp crawl space include termites and carpenter ants.

Crawl spaces with vents or without proper encapsulation are vulnerable to humidity intrusion through the influx of external, humid air and evaporation through the space floor.

While encapsulation and vent sealing are effective solutions against humidity, there is a third source of moisture that needs to be taken care of: condensation. When there is a difference of temperature between the air and elements within the crawl space, such as HVC ducts and pipes, condensation takes place.

Dehumidification: The Definitive Solution for Crawl Space Mold Problems


Having a good dehumidifier running in your crawl space is enough to maintain Relative Humidity (RH) at healthy levels during the entire year.

We recommend you choose a model specifically designed for basement and crawl space environments, rather than generic, hardware-store bought models.

Maryland Mold and Waterproofing provides an effective dehumidifier as part of our Level 4 Healthy Crawl Space Certificate, nationally backed by a Transferrable Lifetime Warranty.

We used Maryland Mold and Waterproofing to remediate mold from our HVAC system and to water proof our basement. That meant coordinating an HVAC company as well as the waterproofing done by Maryland Mold and Waterproofing. Colin Hall was our representative and coordinated this beautifully. He was not only very professional but made sure the job was done to our satisfaction and even came out himself to put our basement shelving back together when the job was complete. He takes pride in his work and made sure we were well taken care of. We finally have a dry basement after years of rain water infiltration. I highly recommend Maryland Mold and Waterproofing and hope you have a similar experience.

Maryland Mold and Waterproofing did a great job at performing mold remediation and crawlspace encapsulation on my house. I was pleased with all aspects of the process, from the initial estimate to project completion. I solicited estimates from three companies, including two national enterprises that advertise heavily. One never bothered to respond. The other sent someone to provide an estimate who was supposed to be a structural engineer (at least that was claimed in the company’s brochure), but had no such credentials on his business card. I had some concerns about possible structural problems, and the rep told me I needed a support beam and four jacks to buttress a “seriously under-engineered” floor. Subsequent attempts to follow up with that company met with no response. I decided to contract with Maryland Mold and Waterproofing and part of the contract included having an independent structural engineer evaluate the space. His evaluation concluded that there were no serious structural issues, just normal settling for a house that is 50 years old. The first MMW crew came out to remove all the moldy insulation and applied a fungicide in the crawlspace. Within a matter of days a chronic problem I have had with my sinuses that I thought I was stuck with for the rest of my life cleared up. A few weeks later a crew came to finish the encapsulation and install a dehumidifier. Both crews worked hard and efficiently in a very confined space and were courteous. I recommended the company to my neighbors, and MMW is doing the work on two more houses on my block.

Nick did a fine job of explaining our project and his team was here on schedule and did quality work with no problems. They treated the mold, encapsulated the crawl space and installed a dehumidifier and a turtl access hatch. Excellent work.

Great experience MD Mold and Waterproofing. The entire team was professional, responsive, knowledgeable, and did their jobs well. We have gone through a complete remodel of the old home we just purchased and have dealt with a million trades and contractors. The team from MD Mold and Waterproofing rose to the top! We'd highly recommend using them. Hats off to you, Nick and Colin, Freddy and the other gentleman who have made our basement water-free :-)

After our drain broke we discovered mold under the floor. Maryland Mold and Waterproofing provided a quote and was able to respond quickly after our agreement was signed. The folks were professional and courteous. Their efforts were much appreciated. They are definitely a company to consider if one has a potential mold issue.
