MMR is nationally certified, fully insured and specializes in all aspects of mold remediation and restoration. Unlike most mold companies, MMR offers free inspections and appointments at specific times (no 4 hour appt windows!). Most projects can begin the next day or a time convenient to you. MMR does not use sub-contractors or undocumented workers at any time. All employees are highly trained and very polite. We will leave your home or business clean and sanitary.

"Overall, job paid for was complete. Hoped getting the wall put back together was an option, but removing the mold was important"

"I called and spoke with Trey regarding his company coming out and servicing my basement. I (still) need the area dried out after my sump pump failed/drained backed up during the recent tropical storm (Isaias). Trey was great (on the phone). Very informative and personable. He told me to send him pictures via text and to call back with my insurance claim number and they would be able to work with me. I called about 3 times and left 2 messages over the course of the next 2 days. Five days later I still have not heard back from Trey or anyone with his company I am VERY disappointed at how he handled this. I had cancelled potential service with another well-known company (I was in their rotation for a call-back) to use Raines because they are local and have great reviews (as I mentioned his reviews to Trey on the phone). Now I am going to just use the other company, which is pushing my appt date even further out. I don’t know why I never received a call back from Raines, but I know this is NOT the way to do business."

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.
