"NAL East, from the very first time I called to get information, to the scheduling, and then their inspection were all amazing. They took such pride in their work, explaining everything in detail.. I got my results report with lab results and copies of the pictures and recommendations later that same evening. I called at 11:30 PM to leave a message but someone actually answered and connected me to the report interpretation department who helped me understand my entire report.

At Tri State Flood Inc, we specialize in comprehensive disaster restoration services. Our team is dedicated to safeguarding homes and businesses from the damaging effects of water, fires, mold and storms. Here’s what sets us apart: Water Removal and Storm Damage Restoration: When water wreaks havoc due to storms or other incidents, we’re here to help. Our 24/7 emergency response team swiftly tackles water extraction, drying, and structural repairs. Comprehensive Services: Beyond mold and water remediation, we handle storm damage repairs, basement flood cleanup and fire restoration. Choose Tri State Flood Inc for reliable, efficient, and compassionate restoration services. We’re committed to restoring peace of mind and protecting your property.

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

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.
