"Look, you're not calling a company like FWDR because something happy has happened... Our refrigerator flooded our kitchen - exposing a small, long-term leak that had slowly destroyed our cabinets, drywall, and floors without for years our knowledge. We now had ourselves a water damage AND a mold problem and had no idea where to start. We were lost and stressed and didn't know who to call. I did a quick search and found FWDR because of all of their amazing Yelp reviews. One call to FWDR turned a stressful situation into a manageable project with knowledgeable support all along the way. Javier was always able to quickly and patiently answer my questions (and I had a lot of questions), he referred us to several companies to deal with prerequisite issues (asbestos and lead testing and removal), and it felt like he was there to walk us through the whole process. I can't tell you how much I appreciate the patience and consideration Javier, Santos, and Margarita showed every step of the way. They worked with the other vendors and my insurance directly to make sure that no time was wasted between services from different companies, the work was quick and thorough (proof received through testing), and every consideration was given to my family with two toddlers and small home during a pandemic - they did their very best to work around us and our day to day needs. I can't thank them or recommend them enough. Attentive, detailed, courteous, patient, thorough, and going well above and beyond in customer service - you really can't ask for more from a company you never really want to have to call in the first place!"

"It is never easy having your kitchen torn up, but Hector from Bay Works Tile and Stone was wonderful to work with.  He met with me a couple of times from January to March regarding this project and went over all the details.  It took a few months for me to decide what type of material I wanted to choose and I finally decided on a travertine.  I ordered the material and we set a date based on when the product would arrive.  I asked Hector to pick the product up for me and he had no problem doing that, and did not charge me more.  The first day of demo went great and at the end of the day I went to look at the travertine and noticed it was the wrong material!  I called Hector when I realized that I had ordered honed not tumbled and he agreed to meet me at a tile shop the next morning.  We found another alternative and he even got the tile price at his cost AND agreed to take the wrong tile back at no additional cost.  What I like about Hector is his easy going attitude and his ability to problem solve and always make you feel like its under control with a smile!  This could have been a really big nightmare for myself and my family with a torn up kitchen and it worked out great.  I even like the tile I picked out better than my first choice!  His pricing is really reasonable and he doesn't nickel and dime you like other companies.  Hector wasn't the cheapest bid, nor the most expensive, and I am so glad I went with him!  Our kitchen looks fabulous!"

Radon Detection and Reduction questions, answered by experts

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.
