Hello! We are a small family owned company. Our love of renovation began in 1998 the year we bought our first home. The last 14 years we have designed and renovated our own homes and since 2010 we had the opportunity to start up our own company and join the renovation business full time and we couldn't be happier. Steve and I have been married for 26 years and we have 3 sons, hence the name 3 Sons Renovation. We work diligently for our customers and our goal is to make sure they are pleased with their project. Give us a call, we love to talk all things renovation. Thanks for reading, Kimberly

"Jeanne is AMAZING! We hired the CDA Inspectors to inspect the house we are currently under contract with; Jeanne was thorough, very observant, so easy to work with and listened to our concerns. The report she sent was very detailed to include recommendations for the issues she uncovered. 47 pages of detailed information leaves little to the imagination so kudos to a nice in-depth look on things we needed to know. Thank you so, so much, Jeanne for alleviating my anxieties and for your most professional, superb and genuine care service!! HIGHLY RECOMMEND!"

Plumbing Installations, Service, and Repair. New Construction and Remodel, Commercial and Residential.

"I recently bought a rental property and within 3 weeks of closing I got a call from my tenant that her kitchen was flooded. I had my handyman take a look and he found that it was coming from a pipe in the foundation underneath the sink. He said a licensed plumber would have to fix it. I call pretty much every plumber in Sandpoint and they're all booked out 1-2 weeks. Nightmare scenario. I finally talk to Kris and he's got a busy schedule too but he says to me he'll stop by and take a look in between jobs the next day. He stopped by like he said and assessed the leak and said he could stop by the following day in the evening after another job and fix it. Sure enough, true to his word he fixed the leak and got my tenant's water back on. Can't recommend Kris enough. Don't know what I would've done if I hadn't found him."

Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

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 testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.
