Installation and service of HVAC, plumbing and roofing systems throughout southern Minnesota. Over 40 technicians offer 24/7 emergency service through out our market area. Maintain offices Mankato, Minneapolis and Rochester, MN. Been a leading provider of HVAC and roofing services for over 100 years.

"The person who rated Schwickerts with a 5 star review because they make sure "the customer is satisfied" is obviously had a different experience than we did. They installed new roofs on our association townhomes and during installation, somehow dislodged several unit's furnace vents as well as someone's water heater vent. When Fall rolled around and furnaces were turned on, one customer had water dripping in her attic and down into her home. They came back several times. Couldn't find anything wrong. On third trip, the employees didn't bother looking in the attic; they simply cut holes in her ceiling and found what they said was a disconnected vent to her furnace. They told her she was lucky they found the problem, because the next step was going to be having to go up on her new roof and cut into it. Unfortunately, after they left, water continued to leak into her home. She could not allow the water to continue to damage her ceiling, so she had someone else look in the attic...and they discovered the furnace exhaust had been disconnected in more than one location, and the water heater vent had been disconnected as well. SCHWICKERT HAD THE NERVE TO SEND THIS PERSON A BILL FOR OVER $400 DOLLARS "INVESTIGATE THE CONDENSATION ISSUE" (TO CUT THE HOLES IN HER CEILING), EVEN THOUGH THE PROBLEM WAS CAUSED BY THEIR SHINGLING INSTALLATION CREW AND NOT CORRECTED. Their customer service for the issues WE HAD after installation was extremely POOR."

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.
