Our family owned business provides professional, eco-friendly cleanup and restoration services throughout Connecticut. We specialize in residential and commercial damage due to water, fire, mold, and natural disaster.

"Tim was wonderful. I put in this project on a Saturday night after finding mold behind a piece of furniture in my finished basement. The next morning Tim already reached out looking to set up an appointment Monday morning. Over the phone he explained the possible process of this project and put me in the books first thing Monday morning. He arrived right on time, looked at the area, and again explained everything. After about 15 minutes of doing his inspection, Tim gave me two estimates, which were both fairly priced. I selected the estimate that worked best for me, and Tim got working right away. Throughout the project, he continued to update me with what he was doing and what he had left. From when Tim arrived to when he left, it took him roughly 3.5 hours for the whole project. He did an excellent job, and I would recommend him to anyone."

We have full compliment of licensed sub- contractors, Electric, Plumbing, Masons etc. Servicing all of New Jersey.

"AMS is our HERO. The city sewer backed up and filled one third of our basement just before kickoff on Super Bowl Sunday. By halftime George had arrived. He calmly assessed the situation, and set up a time to return the following morning. His workers were polite, professional, and meticulous, and did an unbelievable job of cleaning up a horrible mess. By the end of the day the damaged items, sewage , and much of the smell was gone. Huge fans and a germ-killing ionizer ran for three days. When they were finished the floor was bone dry and absolutely clean. It occurred to us that the floor could not have been better cleaned if it were being prepped for painting. So we will be doing so. AMS has innate integrity and a wealth of knowledge across a wide spectrum. Any project can be entrusted to their competent hands. Chester and Jean Lehmann"

Mold Testing and Remediation questions, answered by experts

Is mold in an air conditioner dangerous? Running an air conditioner with mold isn’t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it’s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.

Black mold and wood rot are both types of fungi that form in damp or wet areas, but they cause different problems. Black mold grows on the surface of wood or other materials, while wood rot affects the structure of the wood material. Additionally, inhaling or contacting toxic black mold spores can make people sick. Wood rot spores are not known to cause illness in humans. 

Some of the most common signs of sensitivity or illness from mold include congestion, eye irritation, difficulty breathing, and headaches. These symptoms may not lead to long-term health issues. However, some types of mold, like toxic black mold, can make you quite ill. You may experience respiratory issues, skin rashes, or neurological issues after exposure because of the toxicity. Infants, people with compromised immune systems, and older adults can suffer the most severe reactions.

Pellet stoves burn compressed wood byproducts, making them very efficient and clean-burning. However, even efficient combustion still produces fine dust particles, which could have an effect on the health of vulnerable people in your household, such as infants and people with asthma. A wood stove pro can help determine whether the levels in your home are unsafe.

Results typically come back within 48 hours, allowing for prompt remedial action.
