"I was in a desperate need to find somebody who is qualified to check some mold and do testing in my house. I did the petri dish test by that mold thing you get at home depot or lowes. Needless to say, I hear that it's not as accurate. So since I needed absolute accuracy and the reviews were awesome, I chose to go with this company. I am extremely grateful for both of them. They are super patient. They helped me and more way than I can imagine and I look forward to not only using them again, but also referring them. It's nice to know that there are good people out there who are willing to help you and that are doing things the right way Thank you so much."

Mitch and his staff are a cut above the rest. I have hired West Coast Mold on several occasions when purchasing new properties. I am on the overly cautious side. Mitch always makes me feel at ease and I am always amazed at the level of professionalism and quick turn around time. As his invoices state - he really is a fungi!
Got questions about your tap water? Here are answers to the most common concerns we hear from LA homeowners.
Generally, yes—but contaminants can still enter your water through aging pipes, plumbing issues, or environmental factors. Testing is the only way to know for sure what’s in your water.
We test for a range of potential contaminants including lead, bacteria, chlorine byproducts, nitrates, heavy metals, and more—based on your specific needs and water source.
Over-the-counter kits only test for a few basics. Our certified lab testing is far more accurate, covers more contaminants, and comes with expert guidance you won’t get from a DIY kit.
Pricing depends on your home, water source, and what you need tested. Reach out for a free quote—we’ll recommend the right test with transparent pricing and no upsells.
