"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!!"

"We called Silva’s Painting & Construction yesterday to reinforce two shelves that were sagging. They came and fixed them right away. Then we asked if they could construct additional shelves for our custom storage cabinets in our garage. They took measurements and a sample and constructed them in a very short amount of time. Silva’s and sons, Giovanni and Alex along with their amazing father, Sergio, have been wonderful in helping us with our move to another neighborhood and all the adjustments needed. Highly recommend and endorse this business."

Mold Testing and Remediation questions, answered by experts

Yes, brown spots on a ceiling are usually caused by water leaks and can lead to mold growth, especially if you don’t correct the underlying problem. Ongoing water leaks and moisture issues will almost always result in mold growth, especially if you live in a warm climate. Mold is a health hazard, so get the root problem fixed quickly, clean it, and encapsulate the area to avoid mold formation.

You can find the smell of mold in your house in two ways: following your nose, and using common sense tactics like looking anywhere there’s water first. Mold cannot form in a completely dry environment, which is why you see mold much more often under kitchen sinks than on garage floors. If you have looked everywhere and still can’t find the source, hire a pro, because you may have mold in your walls.

If the smell is closer to mildew or rotten eggs, the issue is probably mold or bacteria buildup in the machine or its drainage system. Clean your washing machine thoroughly, paying close attention to the rubber door gasket, as it can harbor odor-causing residue. Some machines have lint or debris filters that should also be checked and cleaned according to the user manual's instructions. Be sure to leave the machine's door or lid open after each use, as this allows for better air circulation and helps prevent mold growth.

Mold in a basement is harmful as it can trigger allergy symptoms, especially for those with asthma and other breathing conditions. Symptoms of mold exposure include itching, sneezing, running nose, and congestion.

Not necessarily. If the mold is only on the surface or in small areas, you may be able to clean it effectively without removing all the caulk. However, if the mold has deeply penetrated the caulk or the caulk is damaged or deteriorating, you should remove the caulk completely and replace it to ensure thorough mold removal and prevent future growth.
