"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

It is generally safe to stay in a house that smells like sewage for a short time, but you should get the problem fixed as soon as possible. While the level of sewer gas is usually low enough to only cause minor symptoms, prolonged inhalation can lead to headaches, nausea, or respiratory irritation. High levels of gas exposure can be more dangerous, and high concentrations of methane—a component of sewer gas—can pose an explosion risk in enclosed spaces. If you smell sewer gas in your home, ventilate the area and call a professional to locate, assess, and fix the problem, as it will not go away on its own.

Although both bleach and vinegar are effective in killing mold on wood, vinegar is generally considered the better option. Bleach is a potent disinfectant that can swiftly and effectively eradicate most types of mold on wooden surfaces. However, diluting it with water and using it in a well-ventilated space while wearing protective gear is crucial as it can be harsh and potentially harm the wood's finish or discolor it.

On the other hand, vinegar is a gentler and more natural alternative that can successfully kill mold, but it may take longer and require multiple applications for persistent infestations. Vinegar is a safer option that is less likely to cause damage to wooden surfaces, making it an excellent choice for delicate areas or when a milder approach is preferred.

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.

The answer depends on the size of your home, the type of mold, and your ventilation systems. However, the best answer would be no, you shouldn’t stay in your home. Arrange to be away from your home during the mold remediation process, as mold is often most dangerous when it’s being removed due to the particles being released into the air. Some contractors won’t proceed with the remediation if you or other household members are in the home.
