"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!!"

"Need to move not a newly purchased home n 5 days. Spent several hours daily in advanced, getting the house move in ready. Toward the end of each day I noticed that the house was making me feel weirdly sick. I contacted home adviser which steered me toward California Emvironmental Forensic Inspections. They responded, quiclkly with testing. A Had machines in the house, solving the problem the next day. Adam was great to work with at explaining the process. I am so happy to have this problem solved."

Lead Testing and Removal questions, answered by experts

Several different measurements may be used to determine the amount of lead in water. The most common unit of measurement is micrograms per liter (µg/L), which is the same as parts per billion. Another measurement is milligrams per liter (mg/L), which is the same as parts per million.

Lead toxicity comes from inhaling lead or consuming it. Before the 1980s, when the government banned lead from consumer use, it could be found in paint, plumbing, pipes, ceramics, and even gasoline. Lead paint is toxic for the same reason lead itself is toxic, which is why lead poisoning from paint presents the same as lead poisoning from water or food sources, with a slight increase in respiratory symptoms vs. digestive symptoms. Lead paint is most dangerous when it’s old and peeling, cracking, or otherwise disturbed. This increases the concentration in the air and, therefore, in breathable air. 

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

If the lead paint is in a place that is not easily disturbed and is not flaking or deteriorating, you do not necessarily need to remove it. Lead is toxic when dust particles or flakes from peeling lead paint are ingested. If people are not in the area with the lead paint, it may be safe to leave it in place. You still may want to consider encapsulation with a paint formulated for covering lead-based paint, just for an added layer of protection.
