Hello, My name is Mario Licata. I have been building, remodeling, cleaning and doing all around property maintenance since 1986. I am a master window cleaner, studied electrical theory for four years while I was an electrician. I love being a father and a husband but it doesn't pay well so I do these other jobs to pay the bills. I am an honest hardworking person. Over the years I have developed great relationships with other service professionals and that is why I am able to offer such a wide range of services to my clientele. However, rest assured, I am tooled and capable to take care of your work if one of my great service professionals is not able to attend to it. I have been a business owner since 1986 and I have grown and sold 2 small businesses in that time.

"Went well........they moved inside items carefully to get access, used ladders where needed, cleaned sills and outside frames and screens in addition to windows, stayed busy and tolerated my obnoxious ankle biter."

Radon Detection and Reduction questions, answered by experts

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. 

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
