"As a small business owner, I strongly caution others against this HVAC/R company. In over 10 years, they?ve been the least trustworthy and poorest performing contractor I?ve worked with. We experienced repeated service issues, a 25% rate hike without notice, ignored emails, and unreturned quote requests. Worse, we were billed for work that wasn?t done?confirmed twice, including by a third-party inspection with photos. Even when confronted, they deflected and delayed for months. We had to hire another company. They also mis-sized a walk-in freezer due to bad measurements and blamed their supplier. When shown proof it was undersized, they argued with no solution. They later mismeasured again on a replacement bid. Their attitude throughout was defensive, unprofessional, and dismissive. If something goes wrong?and it likely will?they will not stand behind their work. Save yourself the frustration and look elsewhere."

Sewer Cleaning questions, answered by experts

Snaking a toilet is similar to clearing sinks and bathtubs, but there are unique circumstances where you’d have to drain, disassemble, and remove the toilet to fix the clog. For stubborn clogs in the toilet trap, a toilet auger—designed with a shorter cable and a protective plastic encasing—can navigate the tight bends and clear the clog without risking damage to the porcelain. 

Costs range from $200 to $600, depending on the severity of the blockage and access difficulty.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Regular maintenance, such as not disposing of grease or coffee grounds down the sink and routine use of strainers, can prevent clogs.

Black Friday, also known as the day after Thanksgiving, is one of the busiest days of the year for plumbers. Plumbing pros receive many service requests for clogged drains, garbage disposal issues, and clogged sewer lines. Don’t hesitate to call a plumber on Black Friday if you experience emergency plumbing problems.
