"I had a drainage system installed on August 7, 2025. After the first rainfall, I reported issues on August 13. The company returned and said a batch of PVC used did not have proper perforations and had to be manually modified. Since then, the system has continued to show problems, including erosion and exposed drainage pipe within less than a year. In December 2025, I submitted another service request. An appointment was scheduled, then rescheduled to January 2, 2026, but no one showed up and I received no communication. I followed up on January 6 and provided multiple dates I was available, but never received a response. Recently, I reached out again and was told the issue was not covered under warranty and to stop trying to schedule appointments. Very disappointing experience and lack of follow-through."

"Mr. Sydney Bigham did a terrific job! He was quickly responsive, provided a detailed bill with recommendations for a time line from most to least urgent, prices were comparable or better than other bidders. He explained things well, went above and beyond in terms of quality and thoroughness of work, was respectful and appropriately friendly and very knowledgeable. I'll hire him again."

"For the homeowners who discovered mold in their home, and are stressed and worried about the potential cost of the eradication process, you need not look any further than these guys! Craig showed up promptly on the day day and time of our appointment, and my wife and I were immediately impressed and comfortable with his warmth and knowledge! During his assessment, he took his time pointing out the obvious areas and certain problems we never noticed! He did this not to frighten or pressure us, but being informative about the reason for for the presence of the mold! But what shocked us was the total cost of eradication...it was almost half of what 2 other companies had quoted us! His crew of young men worked tirelessly and were friendly and courteous to a fault. No complaints about their cleanup efforts either! We would highly recommend this company in a heartbeat! Ray & Lisa Jones, Delaware, Ohio"

Our patented, demolition-free dry-fogging process is scientifically proven to eliminate mold?not just from surfaces, but from the air itself?in just a few hours. No mess. No stress.

FAQs for mold & toxic material test projects in Columbus, OH

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.
