"Danny was great!!! We are doing a house refi and the appraiser noted a mold like substance in the basement bathroom. I contacted Danny and e answered his phone whenever I called, and was quick to come out to test our mold. In the beginning, he explained that he only tests, does not do remediation and why it isn't good to have a company that does both together. He made this process easy to digest and feel like I wasn't going to go down a road that was an expensive scam. He thoroughly explained the test process, and even told me that it might be just an allergen, which in fact it turned out to be. He sent me a thorough report, and then let me know that the mortgage company could call him directly if they needed any clarification or didn't understand the report."

"Very professional. They did an excellent job cleaning all the air ducts and the dryer vent. Also treated the air conditioning vents in the attic for mold. House smells a lot better now. They would wear shoe covers every time they entered the house. Very reasonable in their pricing. I would highly recommend them."

"Bruce was very responsive to my call. We scheduled an appointment 2 business days after our first contact. Bruce was on-time and very professional. He looked at the basement and said it was a good waterproofing job and looked at the mold area - and it turns out its the type of mold we can remove ourselves by peeling the paint off. I couldn't be more grateful for his integrity in looking at our problem. Because of that I would call them again, use them and will highly recommend them to anyone I know who needs mold remediation."

"We received an asbestos inspection/test for our old plaster walls and ceiling areas. The turn around times were fantastic - inspector was in our area and able to fit us in the same day I called. Sample results and accompanying lab report were emailed within 36 hours. All samples were analyzed by a local lab accredited under the NIST NVLAP Asbestos Fiber Analysis Lab Accreditation Program, so I felt comfortable trusting the results. The inspector seemed very knowledgeable and helped walk us through any areas that could be of concern. Thankfully all samples were negative, but the modest inspection and sampling fees were well worth the piece of mind during our remodel. In short, I highly recommend this company for asbestos testing/inspections."

"Very affordable and thorough test results. I really appreciated that the Moldlab not only provided us with what kind of mold they found but what the affects are on people/pets and then how to get rid of the mold! Our kit was mailed on the same day we ordered it and Charlie was quick?to resend my email results when I accidentally deleted them in my spam folder.?"

"We originally found AMS via Angie's List, and the owner came out very quickly to do a free inspection and talk to use about everything he was seeing -- high potential for mold within the walls of the shower, and other possible areas (on drywall of opposite side of walls, floor, etc.) He showed us all readings on the tools he was using, talked to us in detail about what he recommended -- namely, complete destruction of the tile-walled shower due to multiple instances of bad grout (old shower) and the resultant mold problem within the walls as well as on the floor of the shower. He also recommended some touch-up painting with anti-mold paints where water spotting occurred on our main level ceiling, rather than a more complex/expensive and in his view unnecessary ceiling patch. His crew was excellent, keeping things very clean and on schedule and luckily no major issues were found besides demolishing just the existing shower and raising up the old linoleum flooring followed by completely painting all exposed areas with Aftershock anti-mold primer paint to minimize problems in the future. He stayed at the estimate of about $3K for this work as agreed. (I eventually put in a new shower and floor myself.) For his second visit, he came out for another free inspection of some mold exposed in a main level bathroom ceiling when some plaster that had been wet down a few years ago when doing some cleaning broke away. This was a very small mold spot, and had a companion of some other mold shadowed behind wallpaper. AMS did another free inspection of this problem for me today, and advised that it was something I could definitely handle myself - ceiling and walls were bone-dry all around the area and it would be simple to just remove a patch of the wallpaper (which we plan to remove in this room anyway), scrub the mold with appropriate cleaner, re-plaster the small area of the ceiling that would need it, and then paint with Aftershock primer paint. He even gave me recommendations on places to get all my materials, including the brush I would need to match the existing ceiling texture. Even when I offered to pay for the inspection, he refused -- just asked me to write up a couple reviews, which I'm happy to do. I'm the type of person that likes to find high-quality businesses to form relationships with. As much as no one wants to use a mold remediation service, I would definitely call AMS again if I need to."

"We highly recommend RTS for anyone with mold concerns. We found what we were concerned was mold in our new house. Our realtor immediately recommended that we reach out to Paul at RTS because so many clients raved about him and his company in the past. Despite the fact that he was out of town, he offered to immediately review photos in order to provide an initial assessment. Paul later came to my home and was extremely knowledgeable, detail-oriented, and caring. He did a terrific job assessing a potential leak in our bathroom and then cleaned and treated the area. Paul then very speedily wrote a clear and detailed report with next steps and helpful recommendations on preventing mold from growing in the damp area. He had multiple conversations with us and our builder and even followed up to confirm that our builder was taking the necessary remedial measures. It is obvious that Paul cares for his clients and will take the extra time to make sure all their concerns are addressed."

"It went exceedingly well. I called the company and Bob Ciangalini even answered his own phone. I was very impressed by Bob because he was punctual, knowledgeable, and just plain nice. We knew that the tiles contained asbestos, but when Bob came to our house, he correctly pointed out that the mastic (glue) might also contain traces of asbestos. He removed some mastic and had it tested by a local lab, and he was correct. The price is higher than some other companies, but, in my opinion, this company is worth the extra cost. Bob responds very quickly to any phone inquiry and the removal is professionally done and relatively quick. Would definitely use this firm again and would recommend them."

FAQs for mold & toxic material test projects in Charlotte Hall, MD

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
