"We had a blockage somewhere in our plumbing line and couldn't use our upstairs toilet for over a year. Our contractor Ben Sviri from Creative Home Remodeling Group came out to our condo with his plumber to assess it. Not only did they find the blockage (PVC pipe), they also removed it and patched it up the same day! We definitely recommend them with any home project you may have."

Percolation Tests questions, answered by experts

You can tell if old flooring has asbestos if thick black flooring adhesive is underneath the tiles. However, homeowners should not cut into linoleum floors to look for this adhesive. Instead, hiring a specialist to test the floors is the only safe way to determine if old flooring has asbestos.

Asbestos was most commonly produced and integrated into building products from the 1920s to the late 1980s. In reality, asbestos use should have ceased much sooner because asbestos was linked to cancer in studies produced as early as the 1950s. You can even extend that number past the 1980s due to stockpiled materials and because some countries treat asbestos use differently. It may also be found more in commercial applications than residential.

Asbestos testing takes place in two stages—collection and lab testing. Collection can take less than 20 minutes if a professional manages to get a direct sample. If air samples are required, then the pro will set up a testing device and return to collect it. In both cases, the sample is sent to a lab and results are confirmed or denied usually within one to two days.

According to the National Cancer Institute, asbestos-related diseases can take anywhere from 10 to 40 years for symptoms to appear. The health risks increase with prolonged and heavier exposure. Risk factors also include:

Amount of exposure
Chemical makeup, size, and shape of the asbestos fibers
Length of time a person is exposed to asbestos
Genetic factors
Source of exposure (direct exposure or secondhand exposure from someone directly exposed)

Common areas include insulation, flooring, ceilings, and siding in older buildings. Professionals identify potential risks.
