"The Indoor Solutions crew worked efficiently to treat our basement and remediate the situation. They were excellent in every way. The crew moved furniture, packed up certain items, cleaned up and later restored our basement with new paint and flooring. It’s now a much more inviting space. "

"Easy 5 star rating, they did a great job! I had a short timeline to accomplish as much remediation as possible. Benji provided effective options to restore our space, his bid was competitively priced and he was very communicative and set honest expectations which he then delivered on. His team (Dequan, David, Maurice and Randy) were so accommodating. I wish every contractor I hired worked this way. Thank you!"

"My only regret is not hiring Adam Contracting sooner. From the beginning of the project, I was updated on the schedule and cost. All of the employees were professional, and skilled, and left my house clean after each task. If I had issues or noticed something that needed to be changed the owner addressed the concern immediately. I am very happy with the finished project!"

"Avoid Guardian Basement – False Promises and Poor Customer Service Two years ago, I hired Guardian Basement to fix a water issue on the front wall of my basement. Joel came out, sold me on their system, and guaranteed I would have a dry basement. We also replaced two sump pumps and had the sump well dug deeper. The main selling point was their lifetime guarantee. Fast forward two years, and I have the exact same problem. Every time there is significant rain, water rushes through the same wall. I reached out to Guardian Basement, and Joel scheduled a time to check it out. His tone was completely different this time—defensive and dismissive. Within five minutes, he claimed, “Your system is clogged.” He made this assessment without any real inspection—just by looking at the cement floor and wall. Now, here’s the catch: If you look closely at their so-called lifetime warranty, clogs are not covered. So despite spending thousands of dollars, I’m back to square one. To make matters worse, Joel was incredibly condescending and unpleasant to deal with. After this experience, I looked into their licensing with the state of Maryland and found multiple complaints against them. I am now in the process of submitting my own complaint as well. I would never recommend Guardian Basement to anyone. Save your money and go with a company that truly knows what they are doing and stands behind their work. If I could give them a negative number of stars I would."

"We hired Mighty in 2020 for soot removal after a kitchen pot caused smoke to accumulate all over the apartment. Mighty did an excellent job. They arrived promptly to inspect the damage and did a thorough clean up. I highly recommend them."

FAQs for mold & toxic material test projects in Silver Spring, 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.
