"We were happy to find Tommy and his crew. We had some water damage in the lower level of our home after the heavy rains this year. We had mold in the carpet and water coming in through the porous tile. Tommy gave us a fair quote and their staff handled the process professionally. There were no surprise charges and the crew showed up on time and the office quickly responded to our emails. They did the build back after the mold remediation and we could not be happier with the way it turned out. They did a beautiful job. I highly recommend Pure Restoration if you are dealing with a mold takeover in in your home!"

"On a referral we contacted Baldwin Builders to do asbestos abatement and removal of old air ducts from the attic. Not only were they professional, efficient, and reasonable, but the job was done promptly and they were immaculately clean in the house. I would definitely recommend this company. Hallie was always very helpful."

"We had severe water damage in our home that affected the kitchen, dining room, bathroom, and pantry. Jose and his team came to the rescue and did an exceptional job restoring everything. They worked quickly, stayed organized, and kept the area spotless every day. Jose is incredibly reliable, honest, and easy to communicate with. He always showed up on time, kept his promises, and made sure every part of the job was done right. His crew is skilled, professional, and worked efficiently together. I got three estimates before starting, and Jose not only offered the best price but also finished the job faster than anyone else. The results are clean and beautiful — you’d never know there was any water damage! They truly went above and beyond. Highly recommend Jose and his team!"

"Armando was excellent to work with before during and after the junk hauling process. He was patient to explain everything. No hidden fees. Very considerate when I needed to reschedule. He worked with me and offered recommendations from trailer sizes I needed to what was the most efficient way to remove certain junk. He's truly an expert and a professional."

Customers say: True professional

"Paul was proactive in getting us scheduled and setting up with our popcorn ceiling removal. He also recommended someone to do the sample tests required before removal. I felt the cost they gave us was fair. We weren’t on location when the material was being removed but they did a good job of removing the popcorn ceiling and not causing too much damage / scraps to the drywall so the resurfacing afterwards went smoothly. The only thing that could have been better was no one actually came out to inspect the place until the actual start date at which point it was determined an additional area would have to be demoed and the cost would be slightly higher. In the end we were very happy with the result just would have liked to have avoided the last minute price increase as we were just moving into the place and budgets were tight after paying our down payment. Regardless the work was done precisely and cleanly. Had the air quality tested after asbestos removal and it came back clean! Would recommend these guys to anyone looking to remove their popcorn ceilings"

Biohazard Remediation FAQs, answered by experts

Vermiculite insulation can be hazardous if it contains asbestos. Asbestos fibers, when released into the air and inhaled, can pose significant health risks. The EPA recommends leaving vermiculite insulation undisturbed to avoid potential exposure. It is crucial to have vermiculite insulation tested by a certified professional to determine if it contains asbestos. If asbestos is present, proper precautions should be taken, including containment or removal by licensed abatement professionals.

Mold can come back after cleaning, especially if the conditions are right. Mold loves moist environments, so if you clean a piece of furniture, then put it back in a humid area, the mold can return. Mold may also return if you missed an area during cleaning. A professional mold remediation company can help ensure that the mold is gone for good.

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.

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.

Rockwool insulation is permeable to moisture, meaning that humidity can get inside the insulation. However, since this insulation is moisture resistant, once dry, your rockwool insulation should return to normal without losing performance or becoming damaged. Keep in mind, that surrounding parts of your home can still become damaged from water damage, so it's important to take action if you have a leak in your home even if rockwool is moisture resistant.
