"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"

"They ran interior piping to a sump pit. They had to break up the floor install the piping. Install a sump pump pit so the water was pumped outside. Then recement the trench. This is the second time I have used this company and I highly recommend them. I have had two different crews doing the work and both did an outstanding job."

"I posted an initial review on 2/21/19 on a job done on 1/11/19 to fix groundwater from coming into our basement. The drainage system and sump they installed was not collecting all the water that was coming in, as we had leaking from several areas along an uneven rock ledge. I had reached out to our salesperson by phone and email and never heard back, so I was very frustrated. About 3 weeks after I posted the review, I did get a call from Jeff Allen, one of the supervisors. To make a long story short, he sent out one of their waterproofing specialists to look at the problem. We had already hired an independent mason to try to remedy the problem but he had not yet had a chance to do the job. Jeff convinced me that CT Basement systems would do absolutely whatever it took to fix my water problem. I cancelled the independent mason. Danny, a mason from CT Basement Systems came out and used a very ingenious method to divert all the water to the originally installed water guard trough and then to the sump. It is working beautifully!! I think Danny is a genius and I am so impressed and thankful for Jeff's perseverance and kindness in making this happen. I am now a very happy customer."

Drain Pipe Installation questions, 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.

First, find the cleanout pipe in your yard. Unscrew the cap—you may need a wrench to do so. Then, get a drain snake. You can use a non-motorized one, but a motorized snake will make the job a little easier. Feed the snake through the pipe until it reaches the clog. Spin the snake continuously, but don’t try to feed it through the pipe anymore. Keep spinning until you feel it break the clog apart.

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.

A clogged sewer line is not typically covered by homeowner’s insurance, though some sewer line issues are covered. For instance, damage related to a fallen tree is usually covered. Though sewer line replacement is not covered in a standard insurance policy, some companies offer add-ons for this purpose. Read the fine print before spending your own money.

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.
