"Was polite and professional but didn't have the tools needed to properly unclog my underground gutter drain which was clogged with roots. Tried a mechanical auger that he had but that was all he could do and only pulled thin roots which helped but didn't completely unclog the drain."

They really take pride in there work at this company and completely explained me the process and everything that was involved. I had roots clogging my toilet drain and Sterling was able to locate and remove the root issue and provide me with video evidence of just how clean the drain now is after the service. Very happy with the service provided."

"Really appreciate Mahon (Mike and Robert) to come out the day after New Year's to assist us. Our basement bathroom drain line had clogged and I had spent most of NYE day trying to use a plunger and typical off-the-shelf remedies to fix. This service qualified as a emergency call due to the holiday (as these things happen). We were the 7th customer they were scheduled to see. Luckily, they were in the area for another emergency appointment and were able to assist us earlier than promised. They were extremely careful in lugging the 250lb auger through the house and did not damage anything. They had the drain open and flowing within 10 minutes. Mike and Robert were super easy to work with and very professional. Awesome service! KR"

French Drains FAQs, answered by experts

DIY plunging or drain cleaning chemicals may help minor clogs, but professional hydro jetting ensures long-term solutions.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

You’ll likely pay between $300 and $450 to unclog your toilet with Roto-Rooter. However, the price could change depending on if the clog has caused a lot of damage, which your plumbing pro will want to inspect during your service appointment. Keep in mind that you won’t get a quote from Roto-Rooter over the phone. They have to send a pro out for an in-person cost estimate. You can also attempt to snake your own clog for a lot less, and simple drain snakes cost no more than $50.

It takes hair about two years to dissolve on its own in the drain without the use of any tool or help. Fortunately, using a drain snake, plunger, or any of the actions mentioned above to dissolve the hair will help get rid of the clog in as little as 15 minutes. 

Baking soda and vinegar is a great solution for cleaning your sink drain; in fact, it’s our preferred method. Here’s how to unclog your drain with baking soda and vinegar: Pour in a half cup of baking soda, then 1 cup of white vinegar, and let the two bubble for 15 minutes. Then rinse out with boiling water. This method is much safer than using a chemical drain cleaner gel.
