Guardian Basement Waterproofing understands your basement waterproofing needs. We know how to detect the source of water intrusion and stop leaks before they happen. We help our customers reclaim their basements from water, mold and mildew by doing what we do best: finding and repairing the source of their water-related problems. Guardian uses only skilled and experienced technicians to do the job right the first time! As a basement waterproofing company with more than 40 years of waterproofing experience, Guardian stands behind its work with a Lifetime Guarantee. Additional phone number - (410) 484-9812.

"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."

Including Fire, Water and Flood, Mold, Freeze, Wind / Storm and Hurricane, Burst Pipe and Vandalism damage, etc... Call Now for a FREE Insurance Claim Consultation. No Recovery, No Fee

"Simply put, hiring Insurance Claims Specialist, LLC was one of the most important decisions we made in getting our roof damage resolved. We are responsible homeowners with a strong track record of maintaining our house and property, as well as making sure we have proper insurance coverage. But when weather damaged our roof and our insurance provider denied our claim, we found ourselves in uncharted territory. The process with the insurance provider was daunting, confusing, lengthy, stressful, and not transparent. We were kept at arms length and passed through multiple reviewers. They sent a third-party engineer who showed up unannounced, spent very little time inspecting the damage, and then submitted a report that had numerous factual errors. That report then became a baseline for the insurance company! We were buried in red tape and going in circles. Wayne was able to quickly step in and, using his extensive expertise and knowledge of the regulations and insurance process, got right to the point. As a respected, experienced adjuster, his analysis and steadfast conclusions carried weight. In what could have been a disputed claim that may have taken years to resolve, he cut through the red tape and was able to resolve the matter in our favor within months. In a world where home owners are kept at arms length and treated with skepticism, Wayne was treated with respect as a knowledgeable expert whose views were grounded in experience. When he spoke, people listened. Wayne was very candid and responsive to us. He kept us out of the process details and acted as our representative, while keeping us appropriately informed. He made the process much less stressful! He got the right people to listen and move forward with the right decision. Again, one of the best decisions we’ve made. We highly recommend Insurance Claims Specialist, LLC without reservation."

FAQs for mold & toxic material test projects in Chester, 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.
