Customers say: Terrific value

"Jack is a straight shooter and goes over the problems he sees and only positive solutions. Jack is personable and tried to save you money versus over sell unnecessary improvements. We need our foundation patched for leaks and his crew went over and beyond the work we thought we needed. Waterproofed our outside issues and then waterproofed the inside with paint. They cleaned up our crawl spaces as well as under the basement stairs. Jack even threw in a fire extinguisher and 2 water detectors. Great man, proud of what he does and loves to please his customers. HIghly recommend. Oh, his crew keep everything clean and when they left you would never have known they dug into our driveway and backyard to install leader drains from our gutters."

"Pros: VERY fast response time. I had a small leak in the kitchen. It was not an emergency, but they had someone at my house in 2 hours even though it was a Saturday. The technician gave me an estimate, had all the parts, and fixed it in less than 2 hours. Work was fine. Cons: Very expensive. Replacing the drain, basket and trap cost $870. It was worth it to me for the speed, but I was quoted $480 from another company if I could wait a week."

French Drains FAQs, answered by experts

Usually it’s fine to leave a toilet clogged overnight, as long as it’s not close to overflowing. In some cases, the extra time may give the clog time to work itself out. For example, if it’s caused by an excess of toilet paper, letting it sit could result in the clog dissolving and you may be able to simply flush it away by the time you wake up. 

Only let it sit though if you have more than one toilet in the home.

Although linear drains allow water to flow quickly and efficiently, they tend to clog more easily than traditional drains. Linear drains are flush with the shower floor, allowing soap scum and hair to potentially build up. They’re also longer than other drains, allowing for more space to let debris fall into the drainpipe. 

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.

Anything from debris, rust, ice, and even poor installation can cause clogs in your plumbing vents. Some signs of a clog include slow drains, gurgling sounds in drains and toilets, and bad odors. The bad odors are the most concerning, as these can include methane and hydrogen sulfide. Contact a plumber to come take a look if you notice any of these signs.

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.
