"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

Figuring out why you have a musty smell in your house is the first step to getting rid of it. Mold or mildew is most likely causing the unpleasant odor. People use these terms interchangeably, but they’re actually different.

Mold is a fungus that loves to grow in moist, humid places. It’s typically black or green and has a raised, uneven texture. Stay vigilant for signs mold may be growing in your home. 

You’ll find mildew growing on your shower walls and in your bathroom’s nooks and crannies. It’s a specific type of mold that grows flat. Mildew is usually white, gray, or yellow.

Touching toxic mushrooms will generally not cause harm unless you consume them. It's important to thoroughly wash hands after handling any type of mushroom to prevent accidental ingestion.  

It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.

A stain from a water leak will usually be brown and concentrated in a single area where the water is originating from. You may find it under a damaged section of roof, under an upstairs bathroom, or beneath your HVAC system. Stains from condensation are more likely to be widespread since they don’t come from a single point of water intrusion. Condensation stains also look blotchy and may smell musty, and they won’t be concentrated in a single area on your ceiling.

The most common reason for a smelly dishwasher is a dirty dishwasher filter. The filter is responsible for catching food while your machine is running to prevent clogs. Over time, that filter gets more and more filled with food particles. Cleaning your dishwasher filter monthly can keep the smell at bay.
