Atomic Rooter, Inc. is family owned and operated. We welcome your calls. Should you have any questions or require service, please do drop us a line.

"Steven was the absolute best… arrived at the very start of only a two hour window, fixed the problem in about an hour. Very polite and courteous. I called three plumbers and he was the first to call me back and the only one who would give me a ballpark figure over the phone. The others wanted to come out and have a look for $70. even though I accurately described the job in detail. I’m thrilled to have a reliable plumber! A more than satisfied customer, Lora Harrigan"

French Drains questions, answered by experts

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. 

Yes, hiring a drain cleaner is worth it, especially when compared to the cost of not being able to use a sink, shower, toilet, or bathtub and the potential damage that flooding can cause in your home. You might try a temporary drain cleaning liquid or snaking it yourself, but if the clog is out of reach or these methods do not work, then hiring a professional drain cleaner is the way to go.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Conventional drain cleaners, like you might buy at the grocery store, use bleach (sodium hydroxide) as the main ingredient. On the contrary, biodegradable drain cleaners use gentler ingredients such as baking soda, vinegar, and boiling water to clear out drains. 

Bleach is extremely corrosive and releases harmful gasses—hence the need for wearing safety protections like rubber gloves, eye goggles, face masks, and long sleeves and properly ventilating the room while using bleach. Biodegradable cleaners, however, don’t use bleach. Therefore they are safer to use, especially if you have a house full of children.

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.
