"They were the third mold company to work on my problem and the only one to get it right. Showed up quickly, worked hard to remove a shower and floors in upstairs bathroom and destroy mold throughout and also removed ceiling from dining room below and treat that area. Their knowledge was apparent, and I have great confidence in their expertise and work product, especially after a couple of disappointments with other mold "experts" prior to engaging Premier. Very high rating."

"The inspector was professional and thorough. The report was timely and the company's representative called me to explain the results of the test. I've emailed him to request clarifications and am awaiting his reply. The only negative thing is that after our telephone conversation he transferred me to a 3rd party company who markets mold removal services. The rep there tried to sell me his product. I didn't buy it yet."

"Shane was my first contact (via phone) and was very knowledgeable and went above & beyond to answer all my questions. I tend to have pretty good discernment, and I immediately sensed I was dealing with an honest, straightforward company. Shane offered me an appointment 2 days later that s fast! Awesome when you re concerned about mold! Ray came to our house (a several hour drive to the Redding area!), and was prompt & called ahead to be courteous. Total genuine and nice guy (especially bc he s a dog lover ;) He wasn t rushed at all, answered all our questions (we had a lot), and actually said he likes & welcomes questions! After we received our report & invoice, I THOUGHT I was messaging my husband, lol, but I texted Shane: Thumbs up! They did thorough testing, & the price was still what was initially quoted! I highly recommend these guys!!"

"Leo Tocchini responded immediately..same day as my Call regarding smell and potential moisture issues in crawl space of manufactured home. He monitored a number of areas around my home and in various places of crawl space for moisture levels. I was reassured when his monitor indicated within normal range. We then addressed seismic retrofitting procedure initiated by me for a potential future project. Leo explained what was involved and answered my questions thoroughly. I noted he is kind, attentive, excellent at clarifying procedures and rates. I inquired about the full scope of his work for future projects for myself and for a friend who is currently desiring to live in this area and will need to have his potential home inspected and assessed thoroughly before purchasing. I recommend this company highly. I think it is a rare Gem given myexperiences having purchased multiple properties during my lifetime. A 10 in my view."

FAQs for mold & toxic material test projects in Sebastopol, CA

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.
