"Outstanding service! We had a pretty nasty mold problem, which was taken care of incredibly fast and efficiently. You immediately could tell that Kirill really knew what he was talking about. Very knowledgeable, highly professional, and always on time. The same goes to his crew."

"Overall they did NOT do what they were paid to do. 1) They were paid $25,000 to document and remove the contents and on numerous occasions they opened a drawer and took one picture, or they missed an area entirely. I would say about 30% of the contents were documented in this way. Their job was to document everything so we could file a comprehensive claim. I personally spent over 150 hours working on the contents inventory to make up for their shortcomings. 2) They were paid an additional $5,691.95 to clean some of the contents that could be salvaged. Numerous items, we can only document 14 of them, are missing from the cleaned contents totaling a value of over $7,000. WDR's response was oh we made a mistake and disposed of those items and you will be reimbursed by the insurance company for their value (of course depreciated) so no harm was done. Of course there is harm!! These items had not only material but sentimental value! We lost everything in my parents home of 50+ years and they just threw the things away. Very Very unprofessional. 3) In the boxes of items that were cleaned and returned we have found items that were never ours, how many people have they switched or lost items on??"

"It’s been a while that I wanted to have a company that can come over and check the house for any problems that increased my monthly bills and to fix them at a normal price. I came across this company and I scheduled a meeting with Ezra and Charlie to come over and see/check. Ezra and Charlie checked the house for more than 2 hours and they found out that some of the windows were old and needed to be replaced with new ones. In addition to that, they recommended me to remove the water heater and to install a tankless system that will provide me with hot water only when I need and by having that, my bills will be reduced.The Quote that I got from him was good enough (to my opinion) and I retained them for the job. The work that they did proved to be good one and I see that in my monthly bills. It was a 2 weeks work and I am completely happy with my decision to hire them."

FAQs for toxicity and mold removal projects in San Francisco, CA

Remediation should keep mold from returning as long as the moisture source is eliminated. Fix leaks, control humidity, and replace water-damaged materials, then schedule periodic inspections to stay ahead of new growth. With those safeguards, your home can stay mold-free for the long haul while protecting both health and property value.

Most pros recommend leaving the home while they work on mold remediation. Removing mold stirs up airborne spores that can aggravate respiratory issues, and contractors can work more efficiently in an empty space. A short, temporary relocation keeps everyone in your family safe and lets the crew finish the job without interruption.

Mold shouldn’t return once the moisture problem is fixed. Stay vigilant: repair leaks right away, keep humidity below 50 percent with a dehumidifier placed in damp areas, and improve ventilation where needed. Routine checks for leaks and mold and quick repairs go a long way toward keeping your home mold-free.

Mold spores can trigger nasal congestion, throat irritation, coughing, wheezing, eye irritation, or skin rashes. People with asthma, allergies, or weakened immune systems often feel the effects sooner and more intensely. Some molds also release mycotoxins linked to serious respiratory or neurological issues. Swift remediation and better ventilation are the best defenses.
