"I did not know I had a high radon level. I contacted Gardner and they installed a remediation system. It took 4 men 9 hours to do the work. When it was done it looked professional and they cleaned up as well."

"Lifetime radon service did a great job of explaining the process of installing the remediation system as well as options we had to help control the costs of the project to within our budget. They were also flexible and allowed to replace the sump pump on our own prior to installation so that we were able to install the model of sump pump that we wanted."

"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"Todd Szada at Umbrella Environmental was awesome! He recommended that we get our vinyl tested for asbestos prior to any attempt at removal - the logic being that if the material did NOT contain asbestos, there would be no need to remove the material. He promptly visited our residence soon after we reached out and obtained a sample, had it tested and let us know that the vinyl did not contain asbestos and there was no need for removal. He saved us a great deal of money and simultaneously sacrificed additional business to help us. Todd is a consummate professional and we are very grateful we found him!"

"This company is great to work with. They did some mold testing on parents’ home and did excellent work. They also did some work on my home. They replaced a water heater and bathroom fans. He was easy to get a hold of, personable and come over right away."

Biohazard Remediation FAQs, answered by experts

Toxic drywall has a sulfur smell, similar to rotten eggs or poop. It’s often a sign that the drywall mud is expired, there’s mold or mildew growth, or there’s a leak in your home. Drywall can also absorb moisture during storage, transportation, or installation, resulting in a distinct musty odor.

In some cases, yes, it’s safe to spray hydrogen peroxide on your mattress, but the solution can damage memory foam mattresses, so you should only use it on non-memory foam mattresses. If you have a standard spring mattress, you can mix hydrogen peroxide with cold water in a 1:1 ratio and spray that on your urine-soaked mattress. If you’re cleaning pee out of a memory foam mattress, swap out the hydrogen peroxide for white distilled vinegar, or call in a professional mattress cleaner to avoid doing damage to your mattress.

Depending on the location of the water leak, it could go undetected for weeks, months, or even years in some extreme cases. Most homeowners who have plumbing leaks have slow drips, so you might not see signs of damage until they become severe problems. It’s a good idea to have a plumbing inspection done annually and to take steps yourself to check for leaks, including inspecting your floor, walls, and ceilings for signs of water damage, monitoring your utility bills, and looking for water around appliances and fixtures.

The duration of mildew smell in carpets depends on several factors, including the extent of moisture, cleanliness, and ventilation. If promptly addressed, the smell can diminish within a few days to a couple of weeks after thoroughly drying and cleaning the carpet. However, in severe cases or if not properly treated, the smell might persist. Persistent odors could indicate deeper mildew growth, requiring professional cleaning or, in extreme cases, carpet replacement to completely eliminate the smell.

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.
