Indoor Air Quality has never been more important as we all spend more time at home with our children and even aged parents. Often the young and elderly have a compromised immune system that makes them especially susceptible to airborne particles. Microgard takes this health concern very seriously and we do our best to answer your call promptly and get to your home in the same week in most cases! Mold can easily aggravate a variety of symptoms so we consider your call to be as urgent as you do.

"Kerry was GREAT! He came do to an inspection, spent a LONG time checking the nooks and crannies of our basement, and educated us about what to look for if there is mold. He found one old item (instrument case) that had mold on it which is what was causing the slight smell (and I'm sure it had the mold when we moved in a couple of years ago). He then told us we were actually okay - no remediation needed! I think we have all come to expect that if someone COULD get a job out of us - even if it was nott really needed (we're all such cynics now, right?) - they would. It was refreshing and nice to meet someone who tells you how he sees it. If we ever do have a problem, he is definitely our guy. Choose MicroGard - you won't regret it."

"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

Kevin at All Clean Environmental Services took my panicked call on a Saturday and listened in detail about health concerns regarding “moth ball odors” in my family’s rental property.

FAQs for mold & toxic material test projects in Harvard, MA

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.
