"The experience with Justin at Fire & Water Damage Recovery was excellent. They were referred by the plumbing company that serviced my sump pump. We still got 3 estimate, Justin's estimate was in the middle but I felt good with Justin based on our phone conversation and the referral so we went with this company. Justin did tell me that he might have estimated on the high side because he does not like to surprise the homeowners. What a surprise when I go the final invoice. The final invoice came in much lower and was very close or lower than the lowest estimate I got. Justin and his team also took pictures of how the place was before and after for me to see. They even took pictures of the pathway that they took to get to the crawl space to assure me that they kept the place clean when they got in and out. I was very satisified with Justin and his company."

"We needed to turn our home into a rental property.  We had started to work with another contractor.  Unfortunately, the contractor had our start date for a month after we needed the project completed.  I searched Angie's List and found S&Y Corporation.  They came to our house, within an hour after my first call and started the project the very next day.

S&Y Corporation is one of the most professional contractors that we have worked with. Their employees are skilled artisans. Our floors, walls and electrical work were a WOW, for us. I was so impressed with their service, that I wish we had found them sooner. I would hire them again, in a heart beat!. Mr. Young Ko takes pride in the work of his team and was good with follow up, before, during and after the projects. Great job!  I will hire S&Y again."

Radon Detection and Reduction questions, answered by experts

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

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.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
