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"

PuroClean, a leader in property emergency services, helps families and businesses overcome the devastating setbacks caused by water, fire, mold and other conditions resulting in property damage. Each of our independently owned franchises pledge to do whatever it takes to respond, restore and rescue properties in all of the communities we serve.

"PuroClean in Stevensville has now worked with me through two separate flood disasters to my home. In both instances they were professional, accessible, and did excellent work. Past reviews on Angie’s List (through 2016) May not reflect the company’s high quality performance under new ownership. I would recommend this PuroClean to family and friends."

PROTECTING BY INSPECTING! Lead poisoning is no laughing matter. Worldwide, about 143,000 deaths per year result from lead poisoning, and lead paint is the most common perpetrator. You can prevent lead poisoning from taking a toll on you, your family, and your home by having your property inspected. Reliable Lead Inspection Services, LLC has helped countless homeowners across Baltimore, MD and the surrounding counties with their home lead inspections since 2014. The state of Maryland requires that all properties – including apartments, condos, townhouses, lofts, and single-family homes – built before 1978 have a new lead inspection certificate every time the property is rented or sold. Even if you’re not in the market to buy or sell property, it is always a sensible decision to have any home inspected before doing renovations. You never know what could be hiding in those walls! I can provide 24 hour results if needed. Available 7 days a week. MDE Lic #15208 Ask us about our Senior, Police, & military discounts!

"Norman, was very friendly, knowledgeable and informative. He explained everything he was doing through the process. I would highly recommend requesting Norman."

"great customer service, shows up on time and they stand by their work. I was worried about a mold smell months after the work was done and they send someone out to look over the house no charge. turns out it was just my dehumidifier, but I would definitely hire them again!"

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.
