"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

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.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

If your home was built before 1978, there’s a chance that any paint on your hardwood floors could be lead paint—especially if it was already there when you moved in. Because lead is toxic, hiring a licensed pro to remove it is mandatory. The average price for professional lead paint removal ranges from $1,500 to $5,300 and depends on the scope of the project.

No, you can’t place hazardous waste in a dumpster unless you specifically ordered a dumpster for hazardous waste removal. If the dumpster company finds hazardous waste that it didn’t approve for dumping, the company will return the waste to you, and you’ll likely face a fine for illegal dumping.

Results from professional lead testing are typically available within a few days to a week (2-7 days), depending on factors like laboratory processing times and the volume of samples being analyzed. Expedited services may also be available for urgent situations.
