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.

"Not a happy customer, very disappointed with the outcome. The mold remediation was contained to a 12 x 24 bedroom and was limited to surface mold (mostly furniture) caused by condensation and humidity. The carpeting was also removed & discarded. The total cost was very expensive ($4,250) for what ended up being 5 hours of work. This is over $800 an hour! Here are a few things we were not happy about; 1. There were plastic barriers taped to the walls during the process which caused the paint/plaster to be pulled off the wall in several areas. Now we have another expense to fix this problem. 2. We had told Kerry to leave us the dumpster for a few more days (since we had paid for it up to a week), but he went ahead and told the company to remove it the following day. 3. We found additional mold on the closet baseboard that had been missed and we needed to clean it ourselves. Needless to say, we do not recommend this company. "

"When I called the mold company for my lab results. They gave me a person named Ricardo Echeverria, Senior Mold Analyst to call for the results. He verbally told me that the cause was something like a remodel, construction going on. There was a red flag for a VOC called Methylene Chloride--Banned outdated paint. I sent Ricardo and email asking if I can have a report of what he said in writing. I only received a contaminants list. I said, I am not a scientist and do not understand the lab results.I never received a response back from him. I called Jeremiah Bancroft a few times and asked for a written explanation of the causes. He could not supply me with a written explanation because it was a legal issue. I asked for his help. I need your help. Jeremiah said, go to your primary care for a doctors note. That was the last time I spoke to him on September 19, 2024"

Lead paint can be found in almost 75% of all housing built before 1978 and a dangerous mold infestation could exist in any home no matter how old the home is. A professional inspection from ASAP Environmental is the best way to protect yourself before you buy.

"We had a pipe break in our kitchen ceiling and an issue with condo owners that felt “the mold was everywhere”. Christopher was amazingly knowledgeable and explained all of the issues without being an alarmist putting us all at ease and did a thorough inspection. As an architect for 40 years he was the best mold expert that I have met and would highly recommend them."

FAQs for mold & toxic material test projects in Hopkinton, 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.
