"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!"

Radon Detection and Reduction questions, answered by experts

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

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.

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.
