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.

  My experience with Maryland Mold was excellent! From the initial walk-through with John, the written  proposal to the installation of my dehumidifiers to help remove significant humidity from my basement was a thorough and detailed process with professional service. Maurice was my technician and his customer service was impeccable! I highly recommend Maryland Mold if you have any water intrusion, humidity or general basement needs or concerns.

We had some water in our basement after a hard rain. Nick was here the next day, identified the problem, and was able to refer us to the right person to get it fixed up. Fantastic service! I hope we don’t need them, but if we did I would call Maryland Mold and Waterproofing in a second!

  I can’t recommend Nick enough. This is the place you should call when you have a foundation issue. His quote was 1/3 of the other quote we got but then he said that to be honest, the problem is probably clogged outlet drains and the water is backing up against the house. He suggested consulting with a landscaper first and addressing the problem, and then we may not need to do anything to the basement. We talked to our landscaper and he can replace the drain hoses/ down spout and direct the water away from the house. Nick, there is a special place in heaven for people like you!

  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.
