Mold Inspection & Radon Testing

We provide radon and mold inspection services with 10+ years of industry experience.

Mold testing includes air quality testing, surface sampling, and thermal imaging. You will receive a report that is clear and easy to understand with lab results interpreted.

For radon testing, SIS uses continuous radon monitors (CRM’s) to perform short term tests. We provide professional results and reports within one business day. The reports show hourly radon readings and an average over 48 hours so you can get a good indication of the radon levels in your home or business.

When your property has a mold or radon problem, the issue needs to be solved quickly and effectively. When working with SIS, we’ll respond right away. You’ll receive an inspection report that is clear and easy to understand with results interpreted.

Since SIS only performs testing and inspections, and not remediation, our reports are unbiased. We won’t magnify a problem in hopes of performing costly repairs.
