Capitol Mold takes the high pressure sales tactics used by large remediation companies, and replaces it with honest interactions. We complete honest and in depth analysis of each job and walk you through every step, with evidence. Available from start to finish, from Assessment to Remediation, we make all of it happen seamlessly. Our services includes Remediation and Assessments (Assessments are not completed for AIQ Test Requests, only for potential remediation) (IAQ Testing is better suited for professionals who only perform testing) Testing Minimums included 2 Air-O-Cell Tests ($440 Minimum not including the Control Test) We do work with insurance companies using XACTIMATE. Our Company is fully licensed and insured for Mold Remediation and Assessments. All standards are followed under NORMI Protocol.

"When a leak was fixed that has caused to water to seep through my floorboards, I learned that I likely had mold in the crawlspace area underneath the flooring. I opened this job on Saturday afternoon fully expecting that the necessary mold remediation would be expensive. Murray at CapitolMold responded right away and came the next day on Sunday morning. Murray assessed the situation and explained my options. To my relief, his assessment was that the mold damage was relatively minor. He quoted me for the work and also explained that because the damage was relatively minor, I could do the remediation myself. Murray took the time to explain in detail how to do the work and recommended the necessary materials. I was very impressed with his honesty and willingness to impart his expertise. I highly recommend CapitolMold. I will not hesitate to call them again in the future."

"I had a terrible experience with EXCEPTIONAL RESTORATION. From start to finish, their service was unprofessional, unresponsive, and completely lacking in accountability. Not only did they fail to resolve the issue they were hired for, but their communication was poor and their handling of the situation caused more stress than relief. Despite multiple attempts to get updates and cooperation, they showed no urgency or respect for the damage done to my property. I regret ever trusting them with such an important job and would strongly advise others to look elsewhere. You expect a restoration company to bring peace of mind — instead, this company brought me nothing but frustration and loss of time and money."

Radon gas testings FAQs

Radon gas is a serious health hazard, as it is the second leading cause of lung cancer in the United States. When inhaled, radon breaks down into radioactive particles that can damage lung tissue. Because radon is odorless and invisible, regular testing every two years is crucial to detect its presence. If you have recently remodeled or started using different areas of your home, like the basement, additional testing is essential to ensure your family's safety.

Yes, you need a radon test to ensure your home is safe. The EPA recommends testing your home for radon every two years and after any renovations. Since about one in every 15 homes has elevated radon levels, regular testing is essential. Including a radon test in your home inspection is crucial when buying or selling a property, and some areas require disclosure of radon levels by law. Don't rely on neighboring homes or regional data; the only way to know your home's radon levels is through testing.

Certified professionals conduct radon testing, including accredited home inspectors and specialized radon mitigation companies. These experts follow strict EPA guidelines and use calibrated instruments to accurately measure radon levels throughout your home. Choosing a certified provider ensures you receive reliable results that protect your family's health and property.Professional testing is crucial for accurate detection and effective mitigation if needed.

Radon inspectors typically specialize in testing and assessing radon levels but may not perform mitigation services themselves. If your radon inspector identifies elevated levels of radon in your home, they will recommend a qualified radon mitigation specialist to address the issue. These mitigation experts install systems designed to reduce radon concentrations effectively, ensuring your home is safe.

No, air purifiers are not effective in removing radon gas from your home. Air purifiers are designed to filter out particles like dust and pollen, but radon is a radioactive gas that cannot be captured by standard air filters. To reduce radon levels, you need a specialized radon mitigation system that removes the gas from your home, ensuring your indoor air remains safe.

While opening windows may temporarily reduce radon levels by allowing some gas to escape, it is not an effective long-term solution. Radon continuously enters your home from the soil, and relying on open windows is not practical or sufficient to reduce levels significantly. To effectively lower radon concentrations, you need a professional radon mitigation system that actively removes the gas, ensuring consistent and safe indoor air quality.
