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."

French Drains FAQs, answered by experts

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

Common causes include hair buildup, soap residue, food particles, and foreign objects. Older pipes can also contribute by facilitating buildup more easily.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.
