"Amazing. YES - you pay a lot - but they rocked, their solution rocked, and the installation was flawless. We just built a brand new home and the builder put in the cheapest 24" deep sump pump possible. We live in an area known for basement flooding so I did my research - had several companies come in - and settled on Connecticut Basement Systems. But my LORD - expensive. But now I know why. Their crew of 3 showed up and laid down plastic mat from our front door all the way down to the basement (at least 200'). It was over kill - but then I saw why. They had to dig a 36" deep pit and a wider hole - and brought up all the mess in buckets. NOT A SINGLE DROP ON THE BASEMENT FLOOR OR ONE THE WAY UP THE STAIRS. In fact - if you didn't see the high tech 3 pump sump pump they installed - you would have never known they were there. EVERYONE was super nice and answered all my many questions. I just spent a year in **** building a new home - and this was the best experience I've had with a contractor in 10 years. Pay the bucks - great product - great installation - great service."

French Drains FAQs, answered by experts

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

Costs depend on clog severity, pipe condition, equipment required, and labor.

The best drain cleaners are biodegradable ones or a mixture of baking soda and vinegar. Strong, caustic chemicals may seem appealing with promises of unclogging your drain quickly, but liquid drain cleaners can cause damage to your pipes over time. Consider making your own drain cleaner with baking soda and vinegar.

If you try a drain snake and various DIY methods for unclogging drains to no avail, bring in a professional plumber to assess the situation. Also, if multiple drains in your home are backing up or you smell sewage, a visit from a plumber is best. You can expect your drain cleaning costs to fall around $250, and this can include an assessment of what’s caught in your plumbing and if there’s a larger, underlying problem. You should also consider calling a pro if you need to snake a toilet, as DIYing this could lead to a cracked fixture.
