Was very knowledgeable and gave honest feedback on how to fix the problem, versus trying to just sell me something. Will definitely use again

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.

Common Crawl Space Problems

Groundwater Intrusion

crawl 1 crawl space

Crawl spaces without adequate drainage systems are vulnerable to water infiltration through leaks and evaporation. Crawl spaces afflicted by water pooling are breeding grounds for pests.

Maryland Mold and Waterproofing can provide modern solutions to water-related crawl space problems.

High Humidity

Untitled design 13 crawl space

Many crawl spaces have dirt floors, which allows groundwater to evaporate into the space. Crawl spaces with vents allow humid air in. All of this contributes to an increase in humidity levels.

Maryland Mold and Waterproofing employs an advanced encapsulation system, with proper vent sealing and floor lining, which takes care of all sources of humidity in crawl spaces.

Mold, Odors & Structural Decay

Untitled design 14 crawl space

Crawl spaces, much like basements, are dark, damp environments. At 60% humidity, mold, and dry rot start to occur.

Maryland Mold and Waterproofing provides and installs modern, smart dehumidifiers, which reduce humidity levels, causing existing mold to dry and die, while also preventing new mold occurrences.
