    Great radon testing company in LA area! They took care of my radon testing in 48 hours. Some other…read morecompanies may take up to 7 days for the same service! You might find the following helpful: Radon is a cancer-causing, radioactive gas.You can't see radon. And you can't smell it or taste it. But it may be a problem in your home. Radon is estimated to cause many thousands of deaths each year. That's because when you breathe air containing radon, you can get lung cancer. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high. Radon can be found all over the U.S. Radon comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon can be found all over the U.S. It can get into any type of building - homes, offices, and schools - and result in a high indoor radon level. But you and your family are most likely to get your greatest exposure at home, where you spend most of your time. You should test for radon. Testing is the only way to know if you and your family are at risk from radon. EPA and the Surgeon General recommend testing all homes below the third floor for radon. EPA also recommends testing in schools. Testing is inexpensive and easy - it should only take a few minutes of your time. Millions of Americans have already tested their homes for radon (see How to Test Your Home). You can fix a radon problem. Radon reduction systems work and they are not too costly. Some radon reduction systems can reduce radon levels in your home by up to 99%. Even very high levels can be reduced to acceptable levels. How Does Radon Get Into Your Home? Any home may have a radon problem Radon is a radioactive gas. It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements. Radon from soil gas is the main cause of radon problems. Sometimes radon enters the home through well water (see "Radon in Water" below). In a small number of homes, the building materials can give off radon, too. However, building materials rarely cause radon problems by themselves. RADON GETS IN THROUGH: Cracks in solid floors Construction joints Cracks in walls Gaps in suspended floors Gaps around service pipes Cavities inside walls The water supply Nearly 1 out of every 15 homes in the U.S. is estimated to have elevated radon levels. Elevated levels of radon gas have been found in homes in your state. Contact your state radon office for general information about radon in your area. While radon problems may be more common in some areas, any home may have a problem. The only way to know about your home is to test. Radon can also be a problem in schools and workplaces. Ask your state radon office about radon problems in schools, daycare and childcare facilities, and workplaces in your area. How to Test Your Home You can't see radon, but it's not hard to find out if you have a radon problem in your home. All you need to do is test for radon. Testing is easy and should only take a few minutes of your time. The amount of radon in the air is measured in "Pico curies per liter of air," or "pCi/L." There are many kinds of low-cost "do-it-yourself" radon test kits you can get through the mail and in hardware stores and other retail outlets. If you prefer, or if you are buying or selling a home, you can hire a qualified tester to do the testing for you. You should first contact your state radon office about obtaining a list of qualified testers. You can also contact a private radon proficiency program for lists of privately certified radon professionals serving your area. For links and information, visit: http://www.epa.gov/radon/radontest.html. There are Two General Ways to Test for Radon: SHORT-TERM TESTING: The quickest way to test is with short-term tests. Short-term tests remain in your home for two days to 90 days, depending on the device. "Charcoal canisters," "alpha track," "electret ion chamber," "continuous monitors," and "charcoal liquid scintillation" detectors are most commonly used for short-term testing. Because radon levels tend to vary from day to day and season to season, a short-term test is less likely than a long-term test to tell you your year-round average radon level. If you need results quickly, however, a short-term test followed by a second short-term test may be used to decide whether to fix your home.

I saw him go back and forth with a flipper who had done improper work on a home, and after calling in a specialist, it turned out Elias was absolutely right. He saved me from issues that could have financially devastated me and my family, and I'm extremely grateful for his honesty and attention to detail. We eventually settled on a home, and as Elias says, "There's no such thing as a perfect home." We're aware of the minor issues with our house, but they're all manageable, and we feel confident moving forward. Overall, Elias does honest and thorough work. He is extremely knowledgeable, pays close attention to detail, and genuinely looks out for his clients. I would definitely recommend him to my friends and family!

The property I was purchasing is in an older building, and his expertise really stood out. He knew exactly what to look for, identified both immediate and potential long-term issues, and answered every question I had with confidence. His inspection gave me the information I needed to make an informed decision and negotiate repairs. On top of that, his communication was outstanding. He was responsive and professional. If you're looking for an inspector who is experienced, detail-oriented, and especially knowledgeable about older buildings, I wouldn't hesitate to recommend him.

We contacted Scope Environmental because they specialize in a wide range of services, including sewage and mold remediation. Veronika was courteous, highly responsive, and scheduled a team to come out the same day. Peter and his crew were professional, efficient, and thorough. They quickly extracted the standing water, debris, and sewage, then applied absorbent materials to the wet areas to remove moisture. They also installed heaters and drying equipment to prevent further damage. I appreciated that they returned over the following days to monitor progress and ensure everything was drying properly. Their support during such a stressful situation made a world of difference. I highly recommend this reliable, family-owned company for anyone needing this kind of emergency cleanup services.

    "Multiple Layers" of Deception and Unprofessionalism…read more.. In my correspondence with Gene K., a representative of Scope Environmental (cut and pasted from Yelp chat room) mentions "We can definitely help. Our asbestos inspection, survey, and lab results pricing is very competitive. It's $625 for the inspection and report. Each sample is $35. No other fees. Generally, results and reports will be available within 24-48 hours". Gene K. also mentioned the following "Some samples have multiple layers, and that can not be determined prior to taking the physical sample. You are welcome to call in so that you can properly comprehend the procedures". However, UNDISCLOSED FEES can creep into the price charged to the customer, e.g. such as the need to test "multiple layers" of one material; so, "No other fees" is (deliberately) misleading and therefore, deceptive. A field inspector (Daisy Flamenco) of Scope Environmental, arrived at the project site and upon seeing the area that needed sampling, asked the homeowner for a ladder to get her modest stature to the sampling material areas. When sampling the ceiling, Ms. Flamenco was barely able to reach the sampling surface (needed to be on her tippy toes), even with a step ladder (provided by the homeowner). ALL sample takers must come fully prepared for all conditions at the work site and not rely on the homeowner to provide tools, equipment or assistance of any kind to do THEIR job! Ms. Flamenco was dressed casually, no respirator or other appropriate protective equipment or gear, which is not only hazardous to herself, but sends the message to the homeowner (overseeing the work), that asbestos is really not that harmful. Even two and a half years following the end of the COVID-19 pandemic, it is appropriate if all workers who enter a home, to wear a mask or at least offer to wear one, but Ms. Flamenco failed to show the occupants of the residence, such consideration. Most (professional) people return to bad pre-pandemic habits, even if to protect the home's occupants from the common cold. What is really inconsiderate and unprofessional, is that Ms. Flamenco had disturbed suspected asbestos containing materials by scraping and cutting away material from parts of a furnace and its ducts, leaving the furnace and ducts out-of-order, i.e. if no asbestos or other harmful materials were found, the furnace and ducts could not be safely and effectively used without first repairing them. Leaving carcinogenic materials exposed (cutting, scraping or otherwise removing and exposing asbestos) to those who live at the work site, is hazardous and unprofessional and should never be done this way. Exposing harmful materials puts people and animals at risk of exposure to carcinogens and asbestosis causing particles! Asbestos sample takers should take measures to seal or otherwise cover, exposed asbestos containing materials (when they are through sampling them), to protect home occupants. This experience was a wake-up call to how incompetent workers can make a bad situation, worse!
