"Matthew from Sila was amazing. Not only did he leave what was a mess, super clean, he put in the time necessary to help make sure that all the changes I wanted were in place. New PVC to the sewer line, new extra tap for the vent I'll need next year, re-routed old drains to not only look better, but everything is now tighter-knit and well-organized. Even threaded rods to bracket the drain and valve so that the whole system doesn't shake when it shuts off. I am thoroughly impressed with the focus, the time, and the result. Sila's pricing is high, but in this case I am convinced that I got what I paid for... a system that I won't have to worry about one bit, for many many years to come."

Sewer Cleaning questions, answered by experts

If methods like hot water or a plunger don’t work on your clogged drain, you can snake your drain to dislodge the plug. This can be a messy process, taking some physical effort and additional time over the other drain-clearing options. You can purchase a drain snake at a hardware store and choose from handheld options or those attached to a drill. Just work slowly, and be ready to call a plumber if you’re unable to reach the clog from your drain or P-trap.

If the toilet is overflowing but there’s no clog, that’s a sign that the issue is deeper in the system, and plunging may not help. A blockage in your home’s plumbing, the plumbing vent, or even city sewer lines can cause toilets to overflow. The issue could also be the toilet itself if the filler float isn’t set to the correct height or if parts are damaged or worn out.

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.

When hiring a sewer line company, you need to consider more than just the quoted price. Make sure to check that the company or contractor is licensed, certified, and insured to protect you both. Check for positive reviews, and you can even request references for extra peace of mind. 

To find the best contractor, you might also want to consider how long the company has been in business doing sewer line cleaning and if they’ve won any industry awards for their work and service. Review potential contracts closely, and look for transparent pricing.

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.
