"I needed someone to test for mold as I had been diagnosed with a pulmonary mold disorder. When they arrived they immediately showed expertise in these matters and were concerned about my overall health and the state of my home. As it turns out one of my biggest issues was dust. To get better and be in remission so to speak the dust has to be reduced in my home first. They stated it would not pass a mold test right now there was no need to test and I needed a special cleaning. If I had the money I would have used them. I ended up getting some family together to get the job done as the price was out of my budget. However, if you have a mold or allergy issue, or any water damage at all I would not hesitate to call this company they care about you, your home, and your health. Thank You, Brandon and Tom."

"The serviceman showed me where the problem was and explained what they would do to correct it. He explained their procedure, what the equipment was for and how they would complete the job. He showed me the end results. The carpeting was covered during the process, and vacuumed after the job was completed. I was very pleased with their work. The only problem I noticed after they left was that their equipment put a gouge in the doorway and in the door of the room that they put their venting tube through to the window."

MD Mold provides comprehensive mold inspections backed by laboratory-grade DNA testing. Our approach goes far beyond basic air sampling and microscope spore counts.\n\nOur Inspection Process Includes:\n • Full roof-to-ground exterior inspection to identify moisture entry points\n • Complete interior assessment with thermal imaging and moisture mapping\n • HVAC system inspection for mold-prone conditions and contamination\n • Collection of air, surface (swab), and dust samples\n • All samples analyzed in our in-house laboratory\n\nWhy qPCR Mold Testing Matters\nTraditional mold testing relies on visual spore counts, which cannot reliably determine whether mold is toxic, allergenic, or actively growing.\n\nWe use qPCR (quantitative Polymerase Chain Reaction) technology to:\n • Detect mold using DNA-based identification\n • Target specific molds associated with allergens and mycotoxins\n • Identify mold that may be hidden \n • Deliver objective, defensible data for remediation decisions\n\n

FAQs for mold & toxic material test projects in La Crosse, WI

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.
