"Arid did an amazing job! The sales rep, Mike who came out to give us an estimate was very knowledgeable and explained how the whole process worked. He was very patient answering my three pages of questions! The work they did and the equipment they installed was exactly as promised. I stressed out for so many years about getting French drains because I heard it was so messy and you get dust throughout the whole house. I followed their printed recommendations and there was virtually no dust in the floors above the basement. The Foreman, also named Mike, brought a crew of seven men and ran the job like clockwork. The job was completed in just 5 1/2 hours. They cleaned up every piece of debris and even washed down my driveway! Mike explained how the system works and left me all the manuals. I went with their backup pump and battery system, which they designed, for extra peace of mind. I would recommend Arid to anyone thinking about getting French drains. Thank you Arid!"

"Arrived on time. Performed work in a professional manner. When first attempt to clear clog showed that clog was not in sink drain line, quickly relocated to crawl space where 1.25 inch copper sink drain line connected to the 2 inch copper drain line that connects to 6 inch cast iron drain line. Worked diligently until clog was removed and proven by sink not backing up and, after flowing hot water, by the 2 inch drain line feeling hot at the point of connection to the 6 inch cast iron pipe and by the sound of the water entering the 6 inch pipe. Checked for leaking sink p trap connections and for the 2 inch plug that was removed to access the 2 inch copper line. Cleaned up work areas."

"We had started to get water coming in from the foundation of our basement. Sean had come to our home to give us our best option and estimate of what work they would end up doing. Overall it seemed like the best choice, and sure enough, it was. We had french indoor drains installed in our basement, along with an updated sump pump with a battery backup incase of power outages. Ever since this was completed, we've had no issues, and our basement is fully dry. It only took a few days to complete, and they did a great overall job!"

French Drains FAQs, answered by experts

Snakes can occasionally enter homes through shower drains, although it’s quite rare. This can happen when they follow sewer pipes or accidentally find their way into plumbing systems. To minimize the risk, consider installing drain covers or stoppers on your shower drains. Always keep drains closed when they’re not in use, especially in areas where snakes are known to be active.

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.

Boiling water helps unclog a drain, but usually only with a harder abrasive such as baking soda or vinegar. On its own, it isn’t the most effective tool. In addition, you shouldn’t use boiling water if you have PVC pipes, as it can soften or melt them. Use a plunger or enlist the help of a pro if you have plastic pipes.

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.

There are a few reasons your snake won’t go down the floor drain. One common reason is a large obstruction in the drain that is causing a blockage. You can remove any debris you see in the drain before trying to snake it. In addition, the snake might not be long enough to reach the clog, or it might be the wrong diameter.
