"Melinda,a very pleasant customer service person,called me promptly this morning 15 or 20 minutes after my post of our need. A tech could come today to unclog our drain. Very pleasant tech came to do the job, Steve. I haven't seen much about pricing for this service.While I was looking for a plumber this morning I did see some ads By other companies to unclog a drain for $250. This company charged $225 for the first hour and was prepared to use a camera if necessary within that price. Very good and briefexperience overall."

"Jon is professional and a man of his word. My wife and I had some leakage in our finished basement. After substantial research, I contacted several companies in the area. Jon and his crew at Eastern responded faster than every other company and offered us the best price for the least hassle. The crew works hard and fast. They were respectful of our home and property and cleaned up after themselves when they were done working. Our interior foundation drain is working great and can sleep in peace knowing that our basement is dry, even on the wettest nights.They stand by their work and even came out to install a false floor under our oil tank after we replaced it., at no additional fee. I would 100% recommend Jon and his crew for all of your waterproofing needs."

"Great experience with Jade Construction and would absolutely hire them again. I had a drainage issue in my backyard and it made it hard to get the equipment in without destroying my whole yard. Jason was patient even though I had to reschedule a meeting twice early on, and acted quickly when conditions were dry enough to do the job. He installed a drain system and leveled out the land and both have helped a ton. Professional, helpful, and did a great job."

French Drains FAQs, answered by experts

You can often unclog a garbage disposal in less than 10 minutes, though sometimes you might need longer if you’re unsure what’s causing the clog. For minor clogs, consider plunging the drain, flushing the drain with baking soda and vinegar, or using an Allen wrench to free the clog. If the clog is more severe, contact a local plumber.

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

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.

Yes, many services include camera inspections to identify the cause of the blockage. Confirm with your provider.

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.
