"Mold Warriors cared more about eradicating my mold - than I even did - and didn't stop until they found and removed every location of mold infestation. Their personal mission was to make sure my home was mold-free and they did it in a way that was remarkably professional, competent, responsive and successful. The first and only call I'll ever have to make with respect to mold infestation in my house. Can't recommend Patrick and Mold Warriors highly enough."

We take pride in combining innovation, industry knowledge and exceptional customer care with every project we do.

"Project Lead: Ben The Job: Rooftop Deck above garage needed to be ripped out and replace, new drainage needed to be installed The Good: Ben was very enthusiastic about the job and is a very nice guy. He made sure to explain what the job would entail, what needed to be done, why the problems were happening, ect. He was understanding about the funds for the job being locked up until the sale of one of my other properties went through. The beginning of the job went great, the framing was done well, more ceiling beams had to be replaced than originally thought which they did for no extra charge and they had some higher quality top layer material left over from another job that they used at no additional cost to us. The Bad: Going back to the demo part of the job, we were told that there was no need to move the boxes and various other things we had in the garage out or to cover them. Nobody covered them and so now we have boxes full of plywood debris from ripping up the deck. After the initial large work was done, a team was no longer sent out to do the finishing work. It was one guy, who came out 2-3 times a week, and we rarely got any notice on what days those would be. Often we were told he would be showing up one day, but then no one would show up with no explanation. Repeatedly we were told “oh, the guy is going to come out and finish the job on x day”, but then no one would show up, and when he did the job was not finished. We were told the job would take 10 days (and that that was estimating on the long side). The job was started on March 29th and didn’t finish until May 19th. It happened several times that Ben asked if I was free for him to come and discuss things later in the day, but then he would be a no show. There was a general lack of quality control with the finished work. Instead of quality control being done by the contractor, I had to go and find all of the problems myself (of which there were many on the first pass) and complain about them. Then the one guy came out a week later to fix them, but then new things came up, and I would have to complain about them, ect. In the end I just kind of felt it was ‘good enough’ and was so exhausted with the back and forth and taking time out of my work day to inspect the work and discuss what was wrong I just said it was fine so I could go on with my life."

Mold Testing and Remediation questions, answered by experts

Through air sampling devices and surface swabs in key areas of concern.

Exterior paint contains a higher level of VOCs, which can be dangerous if you’re exposed to it for a long period of time. The good news is that paint’s toxicity reduces significantly once fully dried and cured. Do not keep open exterior paint cans in your home, basement, or garage, exposing your household to harmful chemicals over time.

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Black mold and wood rot are both types of fungi that form in damp or wet areas, but they cause different problems. Black mold grows on the surface of wood or other materials, while wood rot affects the structure of the wood material. Additionally, inhaling or contacting toxic black mold spores can make people sick. Wood rot spores are not known to cause illness in humans.
