"Great experience! We had a clog in our sewer main and Adrian was polite, respectful, and perhaps most importantly, efficient. He fixed our clogged, shared some advice on how to avoid future issues and made sure he left the areas he worked in just how it was before he arrived. His services are fairly priced and he came highly recommended. I would not hesitate to recommend him to my friends and family."

"Mike and Todd did a great job. They replaced my main sewer line very quickly. This is an old house, they did material research to make sure the repair was correct, and they worked in tight space under the house. They were on time and fast, and the work was excellent."

Sewer Cleaning FAQs, answered by experts

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

One way to save money on sewer lines is to install a sewer cleanout since it makes sewer line maintenance easier. Keeping up with maintenance is key to reducing the cost of repairs, so be sure to schedule annual plumbing inspections, install drain guards to stop objects from accidentally falling down drains, and only flush human waste and toilet paper to protect your pipes.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

It's advisable to have your sewer line inspected every three to five years to ensure its proper functioning and detect any potential issues early on. However, the frequency of inspections can vary based on factors such as the age of your sewer system, the type of pipes used, and your property's location. If you notice any warning signs like slow drains, foul odors, or sewage backups, it's essential to schedule an inspection promptly, regardless of the regular maintenance schedule. 

Sometimes, the drain is just too clogged—thanks, stubborn hair and soap scum. In this case, you’ll need a more powerful drain cleaner than you can DIY safely at home. But this doesn’t mean you have to choose a traditional drain cleaner. 

You can find biodegradable drain cleaners at your local home improvement store or online for those drains that need a little more oomph. 

While on the hunt for a formidable drain cleaner, the best options are non-chemical clog solutions that combine enzymes and bacteria.
