"I thought he did a good job explaining what he did do but very disappointed they didn't explain that you had to pay a lot extra money to actually find out what kind of mold if any you had. The $199.00 fee they only looked for mold & tested the air quality. If they found any mold it cost a lot more to find out what type. He did say we had mold in our crawl space but not what kind, that cost more money. Overall good for what he did do."

"Alfred from SS John & Marin Restoration went above and beyond the original mold remediation job parameters and took care of additional remediation issues discovered in unexpected areas. He and his team did a superb job of remediating several mold issues, identifying underlying causes, and implementing strategies that would help prevent problems in the future. Alfred proved to be highly expert, doing thorough and excellent work, and freely sharing useful advice with me as homeowner. The expanded remediation job was completed at a very fair price. I would definitely recommend Alfred and SS John & Marin Restoration for any mold remediation challenges."

"This was the 3rd time we have used Lawson and we have been very pleased each time. The first was a crawl space, the second was to remove old insulation in the attic and replace it. This time we had Lawson install a vent from a bathroom fan and install a Sanadry unit in our basement. No more moisture or musty smell! Great job every time and the men are pleasant to work with and respectful of our home. Neat and tidy work."

"Very professional team spent one full day sealing off basement, cutting drywall/molding/paneling, etc., then disposing of waste in rented dumpster. Took air samples to verify elimination of mold found earlier. Cleaned up nicely! Price wasn't cheap, but fair. <br />"

"My husband and I were considering whether to purchase a home that previously had a stucco exterior. The previous owner remediated the stucco and replaced it with Hardie Plank siding. The windows in this home also had issues. We almost walked away from purchasing this home because we were afraid of what was behind the drywall. We called Joe Fiorilli and he took a great deal of time explaining to us what he could do to help us determine if we had lingering mold issues. During the inspection process, Joe took over 10 mold samples throughout the test. The test did come back positive for several molds, including dangerous black mold. Joe gave us a projected estimate for what he thought the remediation would cost. Based on his reasonable estimate, we purchased thee home. Joe's team came in and removed the drywall and insulation to expose the mold and dispose of the material. The team sprayed the plywood which also had previous water damage. The bill was the projected estimate. Thanks to Joe, when we replace and paint the new drywall, we will be living in our "dream house" which we almost didn't purchase. Joe is thorough, responsive and spends the time to help customers understand the process."

FAQs for mold & toxic material test projects in Wilmington, DE

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.
