Crawl Space Encapsulation in Annapolis & Nearby Areas in MD

Your crawl space may be problematic without you knowing. Nevertheless, these issues may already be affecting you and your family. Sometimes, only a thorough inspection is enough to point out the source of the problem. Common problems in crawl spaces include:

Foul odors
Mold, dry rot & structural decay
Bouncy or sagging floors
Poor indoor air quality
Uneven temperatures and discomfort around the house
Cold floors during the winter
High energy bills

Having your crawl space encapsulated is the ideal solution for moisture-caused problems in your foundation.

The Problem with Crawl Space Vents

Houses with vented crawl spaces are very common across the US, but now it is known this ventilation technique does more harm than good. Modern building science determines that crawl spaces fitted with vents and openings are much more vulnerable to the hazards of humidity, because they allow external, humid air in.

These vents must be airtight sealed to keep humid air out during summer, and freezing air out during winter. This way, the crawl space is protected from the adverse effects of humidity, and you spend less energy in heating during winter time.

  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.

  Nick and his team are very professional and knowledgeable. We didn't end up having a mold problem, but Nick came out to look everything over and provided options regarding a dehumidifier. We highly recommend MD Mold and Waterproofing.
