"Did you know mildew is the gas given off from mold?? Joe offered great advice about the growth of mildew into mold, and my landlord's responsibility to remove it. I feel that he is knowledgable and would perform a thorough inspection. Based on my present economics and quotes from 2 other firms, and not to discount Mold Testing CO at all, I decided on another company. Joe at Mold Testing CO is definitely my second choice."

"I worked with the team of John, Greg and Francisco. John initiated the process with the initial questions and customer service. He deferred to Greg as the work order begin to materialize and i had questions that required field expertise. Greg was very helpful and knowledgeable. Finally, Francisco was equally valuable in the process. He actually spotted another area with mold within the garage ceiling that a competing company did not. The team realized i had not budgeted for the garage and helped come up with a fair price for their services. Throughout the experience, this team was excellent. Highly recommend for anybody needing remediation services."

"I interviewed five companies for a mold mitigation. I chose this company because Ryan the representative was the most thorough in finding places where there was moisture that the other companies did not even look for. They have always showed up on time and have done what they said they would do. Ryan was always available by phone or email for any questions. He was very responsive at all times. Their follow up is very good, testing to make sure there are no mold spores in my home. I would I commend them very highly."

"Great service and very knowledgeable. Provided us with input and talked about options we could consider based on different outcomes. I particularly liked that less-invasive options were considered when gathering test samples so that we didn't have holes in our walls while planning for next steps. I would definitely contact Enviocore if we ever have another water issue arise."

"Couldn’t be happier with the service. He was incredibly thorough — checked every area of the home without cutting corners and explained everything clearly along the way. Beyond being great at his job, he was just a genuinely good person: friendly, honest, and easy to work with from start to finish. If you need asbestos testing done right by someone you can actually trust, look no further. Highly recommend!"

FAQs for mold & toxic material test projects in Denver, CO

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.
