"Mold Neutralizers did a fantastic job for us. Lee is very knowledgable in the area of mold and was very insightful for us. He came very quickly after I requested a quote. Several of the tested areas came back positive for toxic mold, so my wife and I decided to have Lee and his crew take care of things for us. They did it in a timely manner and very efficiently. He communicated with us throughout the process, sending us pictures of the molded areas they remediated. (We were staying in a hotel while they did the remediation because I'm in a wheelchair and couldn't get around while things were torn up.) When they were done and we returned home, the house was extremely clean and ready for the subs to come and renovate the place. The remediation process itself was well shy of a week! We highly recommend Lee and Mold Neutralizers!"

"Hands down the best company I have ever selected to conduct an indoor air test for mold/fungus/asbestos. Bruce was the man who did the job and was so professional at what he does. He gave me advice for future reference, calmed my fears and did such a good quality job on my home. I would definately recommend anyone this company and DEFINATELY RECOMMEND BRUCE. He is the man you want to work in your home!"

"We called Tracy at AIAQ before noon on Wednesday the day before Thanksgiving. He was on-site within an hour. Tracy confirmed we had mold in our carpet and took some samples for lab testing to determine exactly what type of mold we were dealing with. About an hour after Tracy left, I received an email from him with a list of trusted and reliable remediation contractors. We called one of them and they will be here Saturday to assess the damage."

"Very useful and explained things in terms I could understand. Did not do anything that was not approved until he spoke to us. When the report was back from analysis, it was explained so we could understand it."

"Darwin is a thorough professional and I appreciate the assistance he provides. He was exactly on time. He educated us about the different types of mold and more. I could not have had a better professional mold tech. Thank you. I do feel that it is pricey, but if the test is positive for toxic black mold it will be worth every dollar."

"We originally had a company come out for a mold testing who was referred by the plumbing company that came out to repair a leak. The guy gave us the impression they were after a high payout through our insurance company so we went out on our own and found Green Technology Specialist. Darwin was so professional informative and patient for us. He thoroughly explained the process how long it would take and all the tests that would be performed he also helped us save a few bucks by advising us on how to get asbestos testing done. We will be using his referral for the remediation of the findings and rest assured all work we are getting is thorough and justly priced. Thank you Darwin!"

"Very well! He's very personable and arrived on time. He cleaned our ducts that hadn't been cleaned since our house was built - we could smell dust when the heat went on. He sprayed Microban 24-hour in the ducts and the whole house smells wonderful! He's ressonably priced, also."

"I had a minor leak coming from my HVAC system into my closet and called Dan with 1-800 WATER DAMAGE. He showed up quickly, walked me through everything, and helped me understand what would and wouldn’t be covered by insurance. Instead of pushing a claim, he was honest and explained that the repair cost was less than my deductible—and that filing a claim could raise my rates unnecessarily. We ended up fixing it without involving insurance, and I really appreciated the transparency and education as a homeowner. Highly recommend!"

FAQs for mold & toxic material test projects in San Tan Valley, AZ

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.
