"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."

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."

Radon detection and reduction services FAQs
You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay $150 to $800 to hire a local radon inspector, and home-testing kits range in price from $15 to $250 from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.
If radon is present in your home, you can expect to pay around $1,000 for a radon mitigation system or between $780 and $1,250 in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about $4,600 to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing $1,500 to $15,000.
Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.
In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.
