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.

  I have had workmen who come and do a job with out acknowledging me, but both Kenney and Phil were very courteous hardworking as well as hospitable and kept me updated each step of the process as they worked. I must admit their decision making was greatly appreciated and it reflected in their work. For my next project I will request their services again.

  MD Mold & Waterproofing did an excellent job in removing the mold from my entire basement.  The team was professional, knowledgeable, and supportive during the process of emptying a basement full of 26 years of memories.   I highly recommend them.

  We had some bathroom mold that I was worried about and a previous team had come out and told us that it was a full gut job. Thankfully, we decided to get a second opinion, and John assured us that it was just surface level and easily saved us tens of thousands of dollars!

  MMW’s crew, Marcel and Hugo were excellent. They arrived on time, introduced themselves and told us what we could expect as to what they would be doing. They took great care in moving furniture out of the rooms they were working in. They then sealed off the rooms they were in so as not to affect the rest of our home. Throughout the remediation process Marcel kept us informed of what they were doing. When they left they cleaned up and left our home looking the same as when they arrived. We were very impressed with Marcel and Hugo.
