"I was completely impressed with the professionalism and expertise of this company, and the ease of doing business with them. After a preliminary estimate to abate ONLY the perimeter (so that a water barrier system could be installed) Conrad provided a second estimate to abate the entire basement. I'd contacted two other companies for estimates; however, Bluestone's pricing was exceptionally competitive. They showed up on time (7 a.m.) and began work, their crew worked diligently and cleaned up after themselves. There were no hiccups, no last-minute craziness, or surprises. The work was completed in one day and I used their recommended air quality testing company to certify that the environment was free of asbestos particles (or within minimum guideline amounts)."

"I had a water leak from my ice maker. The water line had a pin size hole in it and was leaking downward thru the floor. Once I realized the issue. I had a 6x6 section of flooring to be replaced. I also had sub-flooring, drywall and insulation that needed to be replaced. My insurance suggested I bring in a specialist. Because of the potential of mold. I called Patrick at Mold Removal & Solutions. Patrick came to the house the same day and gave me a quote. A couple days later Patrick started working and was finished in about three days. This is the second time I used Mold Removal and Solutions. Patrick and his crew were always on time and professional. I would recommend Patrick to anyone."

"Rapid mold services and Augustin were absolutely amazing!!! We had extensive mold in our kitchen and they worked endlessly to remediate it all while keeping costs as low as possible. They worked in a timely manner, kept us up to date and educated through everything they did, and had excellent communication. I would recommend them time and time again!"

"We were told by an insurance advisor that we had "cracks in our foundation", a phrase that no one ever wants to hear. We contacted several waterproofing companies to inspect and submit bids. We received bids from the first 2 companies that ranged in price from $3K to $10K. Jerry Meadow with U.S. Waterproofing was the last company we spoke to, and the only honest individual we dealt with--as he properly diagnosed that the issue was not with the foundation, but rather an HVAC problem. Jerry was absolutely correct, and although we did not have the need to hire him, it is a rarity to find such an honest and experienced service professional, and I would highly recommend their services for that reason alone."

Biohazard Remediation FAQs, answered by experts

In most cases, it's not worth the risk of buying a home with mold. You should carefully weigh the pros and cons before making a decision—and there are far more drawbacks than benefits. For one, buying a house with mold opens you up to health risks since mold can cause respiratory and allergic reactions. If the mold is widespread throughout the home, the cost to completely remove it, make necessary repairs, and prevent it from returning is often not worth the cost savings of buying a mold-infested home for a bargain.

If you’re worried mold might still be lingering after you’ve cleaned your items, here are signs to watch for:

  • Musty smell

  • Visible spots or stains

  • Allergy symptoms when you’re around the item

  • Damp or sticky feel.

If you notice these signs, it might be time to let go of the item or get professional treatment.

Toxic mold doesn't have a specific color; instead, toxicity depends on the type of mold and the mycotoxins it produces. Stachybotrys chartarum (also known as black mold) is notorious for its potential toxicity. However, not all molds appearing black are Stachybotrys chartarum. Mold species that appear in various colors, such as green, gray, brown, or black, can also produce mycotoxins. Therefore, it's essential to focus on identifying the type of mold through professional testing rather than relying solely on color to determine its toxicity.

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.

It‘s risky to pressure wash indoors, and we wouldn’t recommend it, but following all safety guidelines can prevent the worst outcomes. Always make sure to use an electric-powered machine over one that’s gas-powered, remove obstacles that could cause tripping or falling, and keep appliances like hair dryers and toothbrushes unplugged and out of the way to prevent electrical hazards.
