"We were stuck in the middle of a plumbing project and couldnâ t complete it. We had been trying for hours to drill a hole into a stainless sink to no avail. We needed an expert! I googled plumbers in the area and found Felix right away. It was our lucky day because he was available and he came over immediately. What had taken us hours (without success) took Felix maybe 15 minutes tops. He came with the right tools as well as his personal experience and we were able to continue on with the installation of our reverse osmosis filter installation. Felix was fast, professional, reliable, and very friendly. Thank you Felix! You saved the day!!"

"Nathan and his crew recently did a partial remodel of our master bathroom. It is now a beautiful tub/shower. They did a wonderful job removing the old shower/tub, and drywall. Now there is a jacuzzi tub, travertine on the shower walls up to the ceiling, and new fixtures for the shower and sink. It looks like a museum piece. They also clean up thoroughly before they leave everyday, there are contractors that are not nearly as thorough as Nathan's team is. A great experience from start to finish, if you are in need of a remodel, don't hesitate to call Nathan"

Percolation Tests questions, answered by experts

While asbestos can’t be directly absorbed through the skin—the fibers are too big—skin contact can still produce symptoms. Contact dermatitis can flare up in sensitive individuals but in most cases, the danger from asbestos comes from inhaling the fibers, or dust, that is produced when asbestos is disturbed. If you touch asbestos by accident, immediately wash yourself and your clothes.

Most manufacturers stopped putting asbestos in linoleum before 1980 due to public concerns about its toxicity. However, the Environmental Protection Agency (EPA) didn’t ban asbestos-containing products until 1989, and a comprehensive ban was not announced until 2024. This means that homes built after 1989 may still have asbestos in their flooring.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.
