"Very satisfied with the whole process. Gerald did an excellent job. Arrived punctually and observed COVID protocols. Explained clearly what he was going to do and how. Showed us preliminary findings, and obtained our permission to take samples for lab testing. We felt he listened to, and responded to, our concerns. Overall a very professional experience. We’ve now received the written report and feel we got what we wanted: an objective analysis of the problem and information we need to remedy it."

"Pro is an important part of their name, and they live it! Protech Environmental is a top notch contractor. We hired them to safely remove vinyl flooring that contained asbestos, after we found them on the WA state Labor & Industries Certified Contractors List. Use this list in combination with Angi before you have any asbestos remediation done. Protech's bid was the lowest bid we received, but that was not the only reason we chose them. Each time we contacted them, they responded within a few hours. We sent Protech and the other bidders questions about their plans for the job, including their workers' vaccination status (they are all vaccinated), how long the work would take, and other things. They responded promptly and completely, and came to the house in advance of the work to make sure they knew exactly what we needed. On the day of the job, they called us several hours before they were to begin, to tell us they had to deal with an equipment problem and would be here about an hour late. They weren't that late, only about 40 minutes. Once they began, they worked efficiently, finishing the work in less time than expected. An important part of asbestos abatement is the clean up at the end of the project, and they did a wonderful job. They did a great job of removing their barriers with only a few spots where their tape took small amounts of paint from the walls. Any staples were removed and the woodwork was not harmed. We are very pleased with Protech's work. We will recommend them to anyone we know and the next time we need a contractor we will look at them first to see if they offer the services we need."

Biohazard Remediation FAQs, answered by experts

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

The Environmental Protection Agency (EPA) only recommends removing mold yourself if the area covers less than 10 square feet. Beyond that, you should hire a local mold remediation company for testing and removal. These companies are trained for the specific task of handling mold and removing it safely and responsibly. The mold removal experts will also be familiar with the different types of mold and the best ways to handle each one.

Turn off the water main immediately. Hire a professional plumber to check on your pipes and make any replacements so you avoid water damage. You don’t want to take any risks with flooding, so it’s best to consult a professional plumber as quickly as possible.

Areas of your home may provide an ideal environment for green or black mold. Most molds love moisture and will thrive in wet or damp areas. Some types of mold, such as Stachybotrys chartarum, grow well on materials commonly used in homes, such as gypsum board and wood. Mold may also grow in areas where there are leaks, such as in bathrooms, kitchens, or basements.
