"I discovered my 10 year old water heater had developed a pretty good leak and called the branch located in Hudson, WI. Brian answered my call and he was very attentive to my needs, quoted me a better price than I was finding elsewhere, and was able to schedule an install in a very short time. I really appreciated his help and understanding of my situation. The install went great and my new water heater is functioning as it should! I'm definitely a repeat customer should the need arise!"

Sewer Cleaning questions, answered by experts

Cat pee has a strong ammonia-like smell, so if you smell cat pee but don’t have a cat or don’t suspect your cat has any accidents, there could be other issues at hand. Aside from pet urine, your house may smell like cat pee from leaking freon from an old fridge, mold, spilled cleaning supplies, or even outside odors from nearby farms.

It can take anywhere from one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

Check connections, clean fixtures, and apply finishing or protective coatings to preserve months' worth of shine and functionality.

Ideally, you might find that you only need to clean the sewer line or remove a clog from the main line. That costs $200 to $300. However, “sewer main clogs can cost upwards of $1,000 to clear, depending on what is causing the clog, distance from accessible cleanouts to the clog, and whether there is occupied space below the clogged line (apartment buildings, condos, etc.),” says Botelho.
