"Shane was my first contact (via phone) and was very knowledgeable and went above & beyond to answer all my questions. I tend to have pretty good discernment, and I immediately sensed I was dealing with an honest, straightforward company. Shane offered me an appointment 2 days later that s fast! Awesome when you re concerned about mold! Ray came to our house (a several hour drive to the Redding area!), and was prompt & called ahead to be courteous. Total genuine and nice guy (especially bc he s a dog lover ;) He wasn t rushed at all, answered all our questions (we had a lot), and actually said he likes & welcomes questions! After we received our report & invoice, I THOUGHT I was messaging my husband, lol, but I texted Shane: Thumbs up! They did thorough testing, & the price was still what was initially quoted! I highly recommend these guys!!"

Lead Testing and Removal questions, answered by experts

“Testing” can start with your senses: Assessing your water’s appearance, taste, and smell can all be good first steps. The best way to know for sure what’s going on with your water is to use a well water testing kit, which can tell you about the specific levels of bacteria, dissolved solids, and hardness of your water with precision. Have a pro test your well water at least once per year.

While not all homes built before 1978 contain lead paint, enough do, so you’ll still want to test to be on the safe side. The federal government banned lead-based paint for homes in 1978, but your state may have banned lead before that time. Around 24% of homes built between 1960 and 1977 contained lead-based paint, while 87% of homes built before 1940 contained lead-based paint.

At-home lead tests can provide accurate results if used correctly, and if the kits are reputable and certified. They vary in sensitivity and methodology, influencing their accuracy. Follow instructions meticulously, ensuring proper sample collection and test execution. While they can detect elevated lead levels, for precise confirmation or if results are concerning, consider professional testing or lab analysis for comprehensive accuracy and guidance on addressing any issues.

How you test for lead in your water depends on the source of your home's water supply. If you have municipal water, your local water system may offer to test the water for free or may connect you to a lab that will perform the testing.

If you have a private well that provides drinking water, you are responsible for testing it for lead. Look for a lab that is accredited by your state's Department of Environmental Protection to perform the test.

Professional lead removal involves identifying and safely removing or encapsulating lead-based paints and materials, using specialized equipment, and following strict safety procedures to minimize exposure and contamination.
