"Mark and helper climbed their ladder outside to the Soffit under the roof overhanging. They cleaned the vent and ran a brush all the way down to the clothes dryer. Now my clothes are dry and the amount of dust has increased due to the opened pathway. Any dust that came outside was cleaned up. Great job. Thanks!"

"After coming home from a vacation and finding our finished basement flooded we used Home Advisor to find help. CARE Property Services responded immediately and did a thorough job of removing the water, and drying out the basement, after removing all furniture and multiple cardboard boxes. After the dry out they returned for the recovery phase, replacing drywall and insulation as needed, painting all rooms and a thorough cleaning of the carpet. Then they put back all the furniture and those boxes not ruined or that we requested to leave for us to evaluate. They worked with our insurance company making the entire process as easy as possible. They were wonderful to work with, professional, helpful and did all they could to prevent any disruption to our life. I highly recommend them."

"Mold Inspection Plus is an extremely reliable and prompt company. The owner James goes above and beyond to keep you in the loop through the whole process and he is kind and very personable. Mold Inspection Plus moves fast and handles each service call with urgency and care. In addition, they are up to date and use modern technology to administer their mold sample tests and provide drawings and photos to you in a very professional and organized pdf format. They also have a convenient electronic system for paying invoices which is such a great option to have. We enjoy working with them and would do all of our property work with them if they provided more than just Mold Remediation."

"Chris was WONDERFUL! I just purchased a home and wanted to have a mold inspection done for peace of mind. Chris took time to explain the process and put my fears at ease with his vast knowledge. He reviewed the test results with me prior to closing which gave me the peace of mind I needed to confirm I was making a good purchase and great investment. I highly recommend Mid Atlantic Commercial Residential Real Estate Solutions. VERY PROFESSIONAL AND COURTEOUS!!"

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