"Cal Coast communication through the whole process was what I needed. I didnâ t know the questions I should ask. I was scared and nervous. Iâ ve never been through this before. Cal Coast took care of everything and problem solved for me throughout the whole process. Not only did he do the water mitigation and mold removal, I hired him to do the put back as well. Everything was done on time. I highly recommend them."

"First, we decided to have Hafa Adai perform pest control services because they answered our request in a timely manner and had a very competitive price. Second, they had excellent reviews. When Vincent contacted us, he provided the information we needed, understood what our issues were, and was very timly in delivering the service. Once here, he surveyed the situation where we had ants inside our house, mostly in the kitchen and bathrooms. He determined that he needed to treat the outside first. In doing so, he found five (5) ant nests/collonies around our perimeter and treated those and the entire outside. He used ant traps on the inside. Since treating for ants, we've been free of these insects and the issues we had on the inside. Vincent's professional service was the answer."

"We were getting our house ready to put on the market when we found mold in the crawl space and one of the closets. MacCraft came out the same day we called— Alex walked us through exactly what needed to happen, gave us an estimate, and got it handled. They documented everything so we had paperwork to show buyers. House passed inspection without any issues. Highly recommend them"

Mold Testing and Remediation FAQs, answered by experts

Just because you find mold in your home does not mean you need to pursue professional remediation services. You can often clean small amounts of surface mold, such as in bathrooms or on windowsills, using household products. However, extensive mold growth, persistent odors, or mold caused by water damage require professional remediation. A good rule of thumb is to hire a pro when the mold is in an area larger than 10 square feet, poses health risks, or affects the structural integrity of your home.

No, it isn’t. This is one of those things that needs to be dealt with immediately because mold will spread at a rapid rate and can go from just one spot on the wall to a serious health risk in a matter of days. Prolonged exposure can be extremely dangerous, so any mold issues (or even suspected mold) need to be dealt with right away. 

Musty smells often indicate the presence of mold, which can lead to various health risks. Inhalation of mold spores may trigger allergic reactions, causing sneezing, a runny or stuffy nose, and itchy or watery eyes. People who suffer from mold allergies or asthma may experience more severe respiratory problems. Certain types of mold, like black mold, can lead to mycotoxicosis, a condition associated with serious health effects like respiratory problems, fatigue, headaches, and skin irritation if exposure continues for an extended period. Those with weakened immune systems, respiratory problems, or allergies may be more vulnerable to the health risks that come with musty smells. Therefore, it is crucial to address and eliminate the source of the odor promptly.

Common areas include insulation, flooring, ceilings, and siding in older buildings. Professionals identify potential risks.

Yes. You should use this product in a well-ventilated area because the fumes can be harmful. In addition, the product is poisonous if swallowed, so keep it out of reach of children. Wood finishing products that are oil based can cause irritation to your skin, so you should always wear gloves when handling it.
