"Very friendly, but critically amateur. Took dust samples from the center/most trafficked parts of each room (inaccurate); threw all the samples into the same bag (cross-contamination). He didn't have any 'official' equipment for bagging the paint chip samplesâ ended up using a discarded ziploc bag that may or may not have been from his lunch that day. The worst offense was finding out after getting results back that he had no idea which sample went to which room, as he did not write this information down. That was the whole job. I asked for a partial refund (despite deserving a full refund) and after initially denying the request, he offered $32 back of the $293 total, because quote: "[he's] a reasonable man." This is not a legitimate business."

"I recently had the pleasure of working with Shawn from Superior Damage Restoration to address a persistent water leak issue in my penthouse duplex unit. The problem was that water was seeping through from under the flooring and down the stairs whenever it rained. Previous contractors had incorrectly suggested that the issue was with the balcony door. Shawn and his team provided a comprehensive explanation of the root cause and took a thorough approach to resolve it. They removed the damaged flooring, waterproofed the balcony door, and even assisted with moving furniture around during the process. Despite their initial efforts, the issue persisted, but they didn't give up. Using thermal devices, they identified that the water was actually coming from the rooftop, down the wall frame studs, and into the floor. Once the true source was identified, they promptly waterproofed the rooftop, and after the next rain, I was relieved to see that no water came through. The team then continued with the flooring work, and Shawn offered an excellent choice of new flooring that perfectly matched the shade of the rest of the unit. I'm extremely satisfied with the work done by Shawn and his team. They were accommodating, responsive, efficient, and pleasant to have around. I'm looking forward to working with them to waterproof other areas of the rooftop to ensure this issue is fully resolved. I highly recommend Superior Damage Restoration for their professionalism and dedication to solving complex problems."

Mold & toxic material tests FAQs

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.
