From start to finish, their professionalism, expertise, and dedication to resolving the problem were truly commendable. Upon contacting Bio 911, their response time was impressive. A knowledgeable representative promptly scheduled an assessment of the mold situation in my home. The inspector, who arrived punctually, exhibited a deep understanding of mold issues and was able to identify the extent of the problem. They patiently explained the entire process, answered all my questions, and provided a comprehensive estimate. Once the remediation process began, the crew demonstrated an impressive level of skill and efficiency. They meticulously sealed off the affected areas, preventing cross-contamination, and worked tirelessly to remove the mold. I was particularly impressed by their commitment to safety, as they used advanced protective equipment and followed industry best practices.

"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."

"We loved working with Repair and Remodel Experts. They were
professional, polite, accommodating and stayed on task. They met our
deadline and the work they did was fantastic. Being a church, we
appreciated their work ethic and the demeanor of their crew. We didn't
have to worry that we would have visitors who might hear inappropriate
behavior or language coming from the construction area (which was right
next to our current office space.

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

A funky smell is the first indicator that mold or mildew is present in your home. You may also notice that you or your household members are suffering from increased allergies or respiratory issues.

However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

Yes, mold can grow on virtually any porous material, including plaster, and can be a pain to get rid of. If you see any signs of mold or mildew growth, call a local mold inspection company to take a look—mold is a health hazard and can spread quickly to other parts of your home.
