Good general communication and came and provided a quick and easy estimate and was able to schedule…read morethe work to be done quickly. They were professional and cleaned up well after the work. I also appreciated that they did attempt to limit the extent of the remediation as much as possible, working to preserve as much of the cabinets and structure. As for the cost, I felt it was quite fair. As a counter-example, I got an email quote from another provider that was almost 3X the cost, but didn't even know what the work was. So recommend you definitely get multiple estimates including onsite to verify the extent of the work required.

I've worked with Casaundra and Todd for property management and water-damage remediation, and they…read moreare truly exceptional. Their professionalism, expertise, and responsiveness stand out in every project. They've handled everything for us--from small, straightforward remediation jobs to an extremely challenging 13-unit apartment building fire where the sprinkler system caused significant water damage. Their ability to manage large-scale disasters with precision and calm is remarkable. Casaundra is especially impressive when it comes to navigating insurance requirements and claims. She knows exactly what documentation is needed, how to communicate with adjusters, and how to move the process forward efficiently. Her knowledge saved us time, stress, and unnecessary costs. If you need a team that is reliable, experienced, and genuinely cares about doing the job right, look no further. Highly recommended!

TL:DR; Will misled us into paying upfront for much of the work that he either didn't complete at…read moreall or did poorly/not up to code. When confronted, he agreed to give us our money back but has failed to make the full payment after 9 months. He also forged our signature to pull permits because he doesn't hold a license himself. We hired Will (aka Wisal) in October 2024 for a fairly large home project, and it was an absolute nightmare. The ordeal he put us through was an extremely emotionally taxing experience for our family. On top of that, he had not honored the refund agreement for the poor and incomplete work. We are now out of the money he still owes us, and we had to find another contractor to correct the terrible work he and his "team" did. Here were the main issues that led us to fire him from our project: 1. Forged Signature: We discovered that Will pulled permits under my name without permission by forging my signature on the paperwork, which he initially told us was pulled under his company's name. 2. Suspicious Electrical Work: Before the scheduled electrical inspection, Will had his team patch up the walls, which would make it impossible to inspect the wires. We found this suspicious, so we asked 4 separate electricians to take a look. Without being able to see behind the walls, they all saw that the work was not up to code. 3. Unnecessary Electrical Upgrade: We told Will we only wanted to rewire the house and to pull the permits. He told us we're required to upgrade our electrical panel. This caused a 3-month delay as we waited for PG&E to do the work. When PG&E responded to us, they told us we actually didn't need the upgrade. We suspect this was Will's attempt to charge us for unnecessary work. 4. Pressured To Pay Upfront: He pressured us to pay upfront for fees associated with the PG&E work (e.g. trenching fees, paving fees, etc). In California, you only need to make a downpayment of up to 10% or $1000 of the total contract price, whichever is less 5. Overpaid PG&E Fees: Will charged us $3,500 for PG&E's engineering advance. We asked PG&E about the charge and were told it was only $2,500. 6. Inconsistent Team: His "team" changed all the time. Will also did not seem to know when his team would work on our house. It was only when we checked and saw that either minimal or no work was done that he would then call his team to ask why they didn't show up. 7. Constant Delays: Will would promise us work would be done by a certain time (e.g. end of the week), but those deadlines were rarely met. For example, he told us the week of February 18th that interior painting and tiling work would be completed by the end of the week. By the time we fired him on the last week of March, that work was still not done. 8. Unprofessional Work: For basic jobs like painting, his team did not cover our floors. We now have paint splatters, scratches, and drywall residue all over our floors and cabinets. After all these issues, we fired Will and demanded a refund, which he agreed to pay on a 7-week schedule. That was back in April of 2025. It's January 2026, and he still has yet to pay us back fully. Do yourself a favor and avoid this company at all costs. P.S. If none of the above points convince you to stay away from this business, run some of the 5-star reviews through an AI detector. Many of them won't pass. I wouldn't trust a business with fake reviews. Would you?

Ah, the joys of homeownership. You think you're just fixing a little leak, and next thing you know,…read moreyou're starring in your own personal horror story--except instead of ghosts, it's a scammy contractor, a roof full of holes, and a rapidly draining bank account. Let me take you back to December 2024. After some heavy rains, we noticed a leak in our living room. Enter Will of Biohazmat (license #957784), who came in like a savior in a time of disaster. We were in a bit of a time crunch, planning to leave for a three-week holiday trip, and let's be real--it does rain in SF in December. Will assured us he'd take care of everything. Roof? Fixed. Ceiling? Restored. Peace of mind? Oh, how naive I was. Red Flag #1: The Mysterious Bathroom Leak One of the first things Will did was open up the ceiling--toward the upstairs bathroom. Now, I had explained, multiple times, that the leak happened after rain. Yes, there had been a small issue last winter, but it was clearly a rain-related problem. Still, Will was on a fishing expedition, hoping to uncover a more "profitable" issue. He eventually convinced me the entire roof needed replacing. I wasn't entirely sure, but hey, the roof was old. Maybe it was time? Spoiler: It was not time. It was a terrible decision. Red Flag #2: The Roofer Who Hates His Job The very next day, a roofer showed up to apply a temporary patch. He was barely inside when he launched into a rant about how Will had been delaying his payments for weeks and how he was planning to quit and work on his own. Now, a contractor's own workers bad-mouthing him before work even starts? That's a neon sign flashing "run" in bright red letters. But between holiday prep and wishful thinking, I convinced myself it would be fine. It was not fine. Red Flag #3: The Disappearing Act We left for the holidays. Will started work in January. I had set up cameras to monitor progress. It was a different roofer - I guess the first one has already quit. Three days before we returned, Will declared the job was done and demanded full payment. I got a few blurry, low-resolution pictures (classic), but on my cameras, I could still see workers moving around. Assuming they were just wrapping up (bad assumption), I wired the money. Terrible. Idea. The Disaster Unfolds Upon returning, I did what any responsible homeowner would do--I climbed up to inspect the work. Oh. My. God. Where do I even begin? Even without being a roofing expert, I could tell this was a train wreck. There were literal holes in my brand-new roof. You know, the thing meant to keep water out. I had a contractor neighbor take a look. Then, I brought in a few proper roofers. They all independently painted the same picture: total incompetence. Some highlights from my roof's tragic new look: The roofing material wasn't properly heat-sealed, meaning large sections could be peeled off by hand. Other parts were over-torched, melting the material and making it brittle. The seals around pipes? Instead of using proper metal flashings and sealants (as is standard), they smeared on some mystery black goo. Around chimneys and walls, instead of applying material properly, they just stuck it on without capping--essentially creating pockets for water collection. Drainage system? Not sealed at all. As if they just assumed water would avoid those spots out of respect. At this point, my frustration had reached Olympic levels. Red Flag #4: Will's "Fix" Was Even Worse I confronted Will, who eventually agreed to send someone to "fix" things. Enter Victor Hernandez, a supposed "partner" of Will's. I asked if he was licensed. Will assured me he was. Victor assured me he was. Fast forward through some back and forth, Victor himself admitted the roof was beyond repair (shocker). So, naturally, Will's solution was... to have Victor re-roof it. Because clearly, the guy whose company just butchered my roof was the right person for a do-over. When I asked what system they'd be using, it was total confusion. They claimed they'd heat-glue the roof but showed me materials meant for cold application. These guys didn't even understand the product they were using. So I asked for Victor's credentials. Nothing. No response. So I did my own digging. Guess what? Victor's license (#1071828) was suspended. He had no roofing license. His general contractor license was revoked due to a lawsuit. I confronted Will. After some discussion, he agreed to pay me back and part ways. Guess what? That didn't happen either as of now. And Then It Got Even Worse... It's been four weeks since that agreement. I'm still owed $9000. No payments. And just when I thought it couldn't get worse--it got worse. Before I had the chance to redo the roof, one of the drainages (the ones they didn't bother to seal) leaked and flooded my baby's room. So let's recap: Replaced a roof that probably didn't need replacing. Got scammed out of $9000. Ended up with more damage than when I started. Flooded my kid's room.

My Highest Recommendation for Bio 911…read more I had a mold problem caused by a leaking faucet and roof at my Mom's house. The mold remediation company that I was referred to, went ahead and started tearing out drywall before any contract was signed. They also would not answer most of my questions and only sent a single photo of what they found and that was only after I asked them to send me photos a second time. I called Bio 911 and spoke to Kirill, the owner of the company. He told me that he doesn't like to take on jobs that are already being worked on by another company, but he told me that he would be happy to come out to inspect and evaluate my problem. He was incredibly thorough. He checked the drywall where visible mold had been seen, checked a nearby restroom even though no mold had been seen in there, the outside wall of the building adjacent to the affected drywall, and even the walls of an adjacent apartment. He detected moisture inside of the outside wall of the building, which was something that the other company had missed, and he outlined the steps needed to correct the moisture problem and mold issue. Kirill did all this work simply because he likes to help people. He did not charge me a penny. How often can you find someone that does things just to help people? It is super rare and I am giving Bio 911 my highest recommendation as a result.

Kirill was very pleasant to talk with about our situation. He was very straightforward and…read moreknowledgeable. This has been a learning experience for me. I do not know if we will end up using them for the immediate clean up but they are on the short list for when we need them later.

Like everyone said, I appreciated Marco's honesty. I initially found them when looking through Yelp…read moresince we were having issues with our bathroom and shed that I wanted to get remedied. After communicating through the Yelp Services option, Marco showed up the morning of during the window of time to get a free consultation. Starting in the bathroom, instead of selling us his services, he told us honestly that we could fix it ourselves by purchasing a few items since they have a minimum charge that wasn't worth it for the bathroom fix. He took the time to walk us through how to fix it and why vinegar doesn't solve the root of the problem. He pointed out things from our paint to our bathroom ventilation issues that we should address. For the shed, he truthfully told us the cost of how much it would be for him to fix it versus us doing it ourselves or hiring some people he was training instead. He wasn't afraid to recommend other people instead of himself and I truly appreciated the information he gave us. We told him we wanted it to be a gym and he even gave recommendations on how to prevent moisture problems in the future. Sometimes it's tough with people being salespeople and selling their services (and I get that they need to sell themselves for their business) but I'm grateful to meet people like Marco who I'd definitely recommend to anyone who needed mold remediation services.

I really appreciate this honest business. Marco came by, assessed our issue and his answer really…read moreblew me away. He said if it were his house, he'd do the job himself to save money and told us exactly what to do. He could've preyed on us and told us we needed a lot of work but he was so honest. I'd totally recommend working with him and if we have any major mold issues in the future, I'd want to work with an owner like him. If he says you need mold remediation, you can likely trust that you really need it. He won't scam you if you don't.

this is the only company that you need to hire related to water damage. when will first came out,…read morehe was providing tips for us before starting the project. he ran tests and gave us a game plan without trying to upsell us and tried to keep our costs low. this was very different from other contractors because other contractors tried to upsell us and didn't put in half the work which led us to ultimately hire all action water damage. the team was very professional on getting the work done and everything was very reasonable. 10/10 would hire them again!!

We hired all action to remediate our house in 2024. Unfortunately two years later, we did an ERMI…read moreand bad molds were still detected so we took things one step further and hired a mold dog. The mold dog flagged all the places that were "remediated" by all action. The drywall with mold were all taken out but unfortunately the studs with mold were just encapsulated and painted over, therefore still exposing us to molds. I've learned that the proper way of treating studs is to remove and replace and if that's not possible, sand, hepa vacuum, antimicrobal and wire brush all the mold out of the studs. Unfortunately, we learned our lesson the hard way. Please be sure to properly vet your potential mold remediation company and understand if they do things properly and rid of ALL the mold. If you need your house to be medically clean of mold, steer clear from this company. They don't care about clients, they just want to get their foot through the door, get rid of the easy mold on the drywalls and not put in the hard work to really get the mold out of the studs. They will just cover up all the mold with white sealant and call it a day. Again we had an ERMI done two years later, which stachy and chaet still showed up. Learn about your molds, these are the baddddd molds. We then took things further and hired a mold dog & she flagged all the places we remediated. They're also not IICRC certified. Wish I had done better research earlier. See photos.
