"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

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Mold thrives in wet and humid conditions, and the bathroom can often be an ideal place for it to grow. If you are worried about mold, it's a good idea to hire a local mold inspector to inspect your bathroom. 

How you handle the mold depends on the extent of the issue. If it's on the caulk or other surface, a deep cleaning with mold-killing products such as vinegar or bleach may be sufficient. For a large infestation, you'll most likely need professional mold remediation.

Yes. Black stains are more than an eyesore. Some black stains can pose health concerns, especially for those with asthma, allergies, or other respiratory conditions. Some stains can also damage the brick’s structural integrity, harming the mortar and resulting in more expensive repairs.

Mold grows at the fastest rate the environment it’s in will let it. The space between your vinyl flooring and the base flooring it’s on is a perfect environment for mold growth, allowing for rapid spread and contamination. Preventing this involves a proper installation of the flooring and constant humidity control.

The CDC does not consider diatomaceous earth toxic to humans or animals, though it can cause skin, eye, and lung irritation when handled without PPE. It's important to note that non-food-grade diatomaceous earth can be toxic when handled or consumed, so homeowners should only purchase the food-grade option.
