"With the recent snow melt and the rain we are having this may be a timely recommendation. I hope you don’t have this need, but if you do I would like to recommend Master Service Company. We had at least six estimates for waterproofing our basement and although not nearly the cheapest, we were impressed by the presentation and the personnel and low key sales approach. So, we hired them! The work was done last week and again we were impressed with the crew doing the work, the care given to hold down the dust created, the quality of the materials used, and the willingness of the crew to keep us apprised of the job as it progressed. The was great care given to cleanup of what is a very messy job. We waited until the repair had been “battle tested”, (and this inclement weather has certainly accomplished that) before writing a recommendation. We could not be more pleased at this point. Again I hope you don’t have the need, but if you do give Mr. Jeff Russell at Master Service a call. Contact: Jeff Russell 317-720-3288."

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."

"Very good experience working with the company. They showed up on time, had all tools needed, kept my house clean with drop cloths, installed all new two bathrooms and a remodel a bedroom also. The owner kept me informed of everything going on and was very knowledgeable about products and installation. I would definitely hire them again. Top rated in my book."

"Very well. Workers arrived promptly and worked steadily. They inspected for mold in my basement, removed duct cover where mold was found, built a new cover, applied mold preventive to the whole basement, and did an awesome clean-up, including vacuuming the whole basement. I was pleased that the job was done well and finished in a day. One worker returned two days later to sand the drywall, which had needed time to dry completely. I appreciate how they explained everything they were doing."

Mold Testing and Remediation FAQs, answered by experts

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.
