"We hired Pure Maintenance of Colorado after another remediation company failed to properly contain mold during cleanup. Pure Maintenance was everything we needed — professional, knowledgeable, compassionate, and extremely thorough. They spent three full days deep cleaning, doing small-particle removal, and fogging the entire house and ventilation system. What truly matters is the outcome: the air in our home feels fresh and clean, and our child, who has mold sensitivities, has had no reactions since the treatment. The difference is night and day. We are sincerely grateful and give Pure Maintenance of Colorado our highest recommendation."

"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."

Customers say: Quality work

"Very happy with the service we received from Healthy Home. We received a deeply concerning air quality report from another company, so we followed up with Healthy Home to get another evaluation. We had a different and wonderful experience with Bob. He was very thorough and tested our home at numerous points in the house for various potential issues, using high-quality, reliable (and it sounds like expensive, haha) equipment. He answered in detail all of my and my wife's extensive array of questions so that we could fully understand the data that was collected and the warning signs to look out for regarding air quality. At the end of the day, we had a lot more knowledge about air quality, and our fears were put to rest about the safety of our home. We'll definitely consider Healthy Home again in the future!"

"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."

"We used Jason for evaluating the Radon for our basement. He was very courteous and polite. We were below the threshold needing remediation, but he was still willing to give me a ballpark estimate should we desire to do something in the future. He also shared some products on Amazon should we want to do our own long term tests. Very pleasant experience and gave us a great deal. I would recommend him and would do business with him again."

"As a Real Estate Agent, i have been a part of hundreds of Home Inspections and i was more than impressed with the knowledge, professionalism, and willingness to educate my Buyers about every aspect of the home. Not an over alarmist like Axium Inspections are, and more friendly than any other Inspection Company that I have worked with in the past. All Agents have their preferred Inspection Company but, I would hire RF before I worked with anybody else."

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.
