We can offer Mold Testing and Remediation. Water Damage. Smoke Damage. Fire Damage. Our owner is on site for all jobs! Call today we work flawlessly with your insurance company.

"I had a poor experience. I hired this company to do a mold assessment in my apartment. I dealt with the owner. First, he requested cash or check payment only. He made an appointment and did not show up or contact me. I had to call him. In one of the rooms, the pipes above and whatever else the cause of the leak was, had been leaking repeatedly for 40 years, and the plaster constantly replaced. I was worried about mold ABOVE the ceiling on the beams and studs and not just the visible mold on the ceiling plaster and I worried it could be black mold. He did not seem to listen to what I told him and he did not use a water meter to check for saturation or a borescope or any other tools except taking a surface sample and air sample (the borescope and water meter I did not know about until after I had paid him for this inadequate job). He did not mention anything I said in the report. He was also rude and unkind and never provided me with a receipt."

"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"

Radon Detection and Reduction questions, answered by experts

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
