We had our crawl space waterproofed and the side yard fixed to keep water draining away from the house. Everything was done quickly and efficiently. I wanted more dirt added to the side yard to grade away from the house and they fixed it the next day no problem. I would hire them again to do similar work.

Maryland Mold & Waterproofing did an excellent job for me and they did it at about 1/2 the price bid by a competitor - a difference of several thousand dollars! The system has been working well since installed, with good effect on all three levels of my house. Their installer was very professional and very considerate, taking care to clean up perfectly after the work was done.

Maryland Mold and Waterproofing came to assess the same day I called and performed the repair the following day. John Rivers level of quality fairness and professionalism is what you hope for when you need this kind of service. I highly recommend this company.

He's been excellent, he explained everything that was happening. He left and even came back to check into the issue more to make sure his estimate was correct. He preformed mold testing and remediation on my home. I would hire his company again.

A plumber found mold in a small, enclosed part of our crawl space. It was so bad he refused to work there until remediated. We'd been concerned about humidity, mildew and odors from the larger, accessible part of the crawl space for some years, so the immediate problem in the small crawl space resulted in us asking MM&W to look at both spaces. John gave us a fair price for the work in both spaces and I was impressed with their technology, so we hired them. The photos from others on Yelp represent the work we had done. It wasn't cheap, but I can now go into both crawl spaces (one thing MM&W did was provide access into the previously closed off small crawl space) without a face mask and without any mold or mildew odors at all. We've even noticed a previous occasional musty odor that was in the house after rains is no longer present. I'll reserve final judgement on the effectiveness of the encapsulation and dehumifier system until summer time, but my wife and I are very pleased so far. We needed a couple small items taken care of after they were finished and they took care of those right away. More importantly, all members of the work crew were professional, on time, and paid attention to details such as cleaning up after each work day. As others have noted John was thorough and knowledgable, and Michele and Danielle were very responsible on the admistrative side of the job. Highly recommended!

I almost never leave reviews, but Maryland Mold & Waterproofing deserves a few minutes of my time. A mold inspection found mold in my home, which was under contract and due to be sold in less than 2 weeks. John Rivers and his team stepped in, and were nothing short of amazing. They eased the buyers concerns, and assured them that the problem could be "fixed". On very short notice, and under a tight deadline, John had a team of guys out at the house. They sealed up the area, cut out some drywall, and did an amazing job of removing and clearing out the mold. 2 days later, the repair crew arrived and replaced the drywall which had been removed, and repainted every surface that had been affected during the mold removal process. There was no indication there had been any repair to the wall when they left. Absolutely exemplary work by John and his crew, again, under a very tight deadline. If you have just discovered a mold issue, or have been waiting to deal with a mold issue that has lingered in your home, Maryland Mold & Waterproofing should be your first and only call. Their work is impeccable, and they guarantee the air test results after their work. Discovering mold in your home is a nightmare, but if you have found yourself searching for a company to help, I can't recommend Maryland Mold & Waterproofing highly enough.

John arrived right on time for the estimate. Did a thorough site survey. Pointed areas where work was needed and, importantly, where action was NOT needed. Crews to perform the work - French drain, roughly 200 ft long - on time and worked very efficiently. Final project exceeded expectations, was very aesthetically pleasing. All debris was removed and yard tidied up. Final invoice matched the estimate exactly.



This was a terrific experience. Very extensive job, executed perfectly by diligent, polite and friendly men. No surprises, no churn. And, again. John targeted exactly what needed to be done and provided advice on what was not required. His aim was to fix the problem without doing (or charging for) unnecessary work.

Found a lot of mold on a wall where a basement toilet leaked into and got out of hand. John came out and did a thorough assessment, looking at some other concerns I had, and ultimately decided that the drywall needed to be removed. I couldn't have asked for a better service! His guys came out and did a great job and the price was very reasonable. I went with Maryland Mold because I saw that they're trusted by a lot of realtors, and for good reason! The basement already smells a lot better and I can rest assured that the job was done right.

OMG! I can't say enough good things about this company. These days it is so hard to find good, reliable and honest contractors. Well, you won't go wrong with Maryland Mold & Waterproofing. To start, making the appointment was super easy. The woman who booked the appointment (whose name I can't remember) was awesome and even worked to get me an appointment a day earlier when i mentioned I wanted to have things expedited which was very accommodating since I called last minute. On the day of my appointment the owner, John, called a half hour prior to confirm the appointment and he showed up on time and was beyond professional. He quickly and throughly accessed the situation which ended up not being nearly as bad as I imagined. I had already prepared myself for the worst case scenario and tons of money going out the door. That was not the case. Ten minutes later and $0 spent I was reassured by John that I didn't even need his services and there wasn't anything to worry about. He was upfront, explained everything in layman's terms and didn't try to swindle me out of money for services that I didn't need. And, did I mention he didn't even charge a service fee for coming out! I HIGHLY recommend this company and he will definitely be my "go to" guy in the future for mold or waterproofing services.

We were selling our home in Gambrills and had a home inspection and mold was

found in our attic. Maryland Mold did a great job in removing the mold and installing

a new attic fan. The job satisfied the new owners and we were able to complete

the settlement.

Maryland Mold & Waterproofing was very professional and did a fantastic job on a leaky basement from a house built in 1948. The workers completed the job on time and the rates were very competitive. I would certainly recommend them to all my family and friends!

As a professional real estate agent, John Rivers and his crew are the only people we recommend whenever any of these issues come up. We can always trust John to give our clients his fair and honest opinion. There have been many times when John has let us know that the problem was small and something the homeowner could fix themselves instead of recommending a bunch of expensive work that is not truly needed. When work has been needed, it has always been completed at a reasonable cost and in a timely manner. He even sticks by his work with a guarantee. Being in a business where these issues can make or break a sale he is truly a life saver. Thank you for all you do and keep up the good work!



Always the Best,
