"I recently had the pleasure of working with Bio 911 for a mold issue in my home, and I am absolutely thrilled with the exceptional service they provided. 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. What truly sets Bio 911 apart is their commitment to transparency and open communication. Throughout the remediation process, they consistently kept me informed of their progress, explaining each step they were taking to address the issue. This level of communication provided me with peace of mind and confidence in their work. Upon completion of the remediation, Bio 911 performed a thorough inspection to ensure that every trace of mold was eradicated. The final results were nothing short of remarkable – my home felt fresher and healthier than ever before. I would wholeheartedly recommend Bio 911 to anyone in need of mold remediation services.

"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 received the phone number of this company from a friend that hired them and he was able to reduce his utilities bills by doing an efficiency audit that includes covering all the openings at the house (windows, HVAC, Doors etc.?.) and then with a machine, running the test and to see from where the house is losing most of the energy and to perform a repair that will prevent that in the future. Ezra and his team of workers came to perform the test and to see what need to be repaired or improved. The audit took close to 5 hours and then the machine that they used worked for additional 2 plus hours. After that was completed, we saw clearly that the problem was the windows and the HVAC. Ezra recommended us to perform a repair to both of them and then to run the test again. After the workers of them finished the repair, Ezra came once again and did the test. He was pleased with the results and so as we. During all the work, we saw how it was before and how it was after. We do recommend this company for that type of work! They are professional and honest people to hire and they carry all the relevant licenses as well."

"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."

Mold Testing and Remediation FAQs, answered by experts

Follow recommendations for removal or remediation to ensure a safe living environment.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Professionals use specialized equipment and techniques to detect asbestos, radon, and VOCs.

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.

Certainly, DIY mold tests are not perfect when trying to determine whether you have a mold problem. They could give you a false positive reading, or they may fail to detect mold that’s behind a wall, especially if the infestation is still small. Ultimately, you should seek a mold inspection if the DIY test gives you a positive result, just to be certain. And if the test is inconclusive, it’s probably worth seeking an inspection from a pro.
