"I can’t say enough good things about Procyon. When a sudden flood in my basement occurred, their team responded with urgency and professionalism, arriving promptly and fully prepared. They quickly assessed the situation and got to work immediately. They ensured that every bit of moisture was taken care of, preventing any future mold or structural issues. I was especially impressed by their attention to detail. They didn’t just focus on removing the water, they also followed through with thorough drying, disinfecting, and post-remediation inspections to ensure my basement was safe and sound. They communicated with me every step of the way, which gave me peace of mind throughout the entire process. Thanks to their efforts, what could have been a disaster turned into a manageable situation. I highly recommend Procyon for anyone in need of reliable and effective remediation services. Their dedication, expertise, and customer care were second to none."

"I hired Kascon to do asbestos abatement in my attic. I worked with Keith Carroll as my primary contact, he was outstanding. Keith was prompt courteous knowledgeable and extremely helpful. The back office crew was equally oppressive in assisting me with documentation billing etc. as were the gentlemen who showed up to do the abatement work. They were neat and meticulous, showed up when they said they were going to show and did a great job cleaning out not only the asbestos but contaminated wood and materials. Would absolutely recommend this company to anyone who needs asbestos abatement work done. Ask for Keith, you will not be disappointed."

Biohazard Remediation FAQs, answered by experts

After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To get rid of a mold smell, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area. Call a mold testing professional for another inspection.

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.

Bleach and vinegar are both home remedies for killing mold and mildew, but neither is the best answer. A professional cleaning company or mold remediation company can do the best job. If you want to attempt killing mold yourself, however, reach for plain white vinegar before bleach. Vinegar is a mild acid, and when used properly, it can kill about 80% of mold varieties, along with their spores. It’s also much safer to use than bleach, as it doesn’t include toxic chemicals and isn’t generally dangerous to human or animal health.

Yes, you can use bleach to remove mold from your aluminum siding, but it’s a powerful cleaning agent, so make sure it’s diluted with water first. A solution of one part bleach and four or five parts water works well. But it’s still a good idea to start by cleaning a small, inconspicuous area of the siding to make sure that the solution doesn’t cause damage or discoloration. 

It’s worth it to get mold remediation as soon as you discover a mold in your home. Mold is a fungus that can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house. Once detected, call a professional mold remediation company immediately to get it taken care of.
