"We had a great experience with Giant Plumbing and couldn't be happier with the outcome. After a previous water line repair by another company didn't meet our criteria, code, or accepted plumbing standards, Don carefully evaluated the situation, clearly explained what needed to be corrected, and handled everything professionally from start to finish. They fully removed the prior work, rebuilt the system to code, and completed the job exactly to our specifications. Their communication was excellent throughout -- thoughtful, transparent, and never rushed -- and the quality of workmanship was outstanding. The final result is clean, secure, and exactly what we had hoped for from the beginning. It was a huge relief to work with a licensed professional who takes pride in doing things the right way. We would absolutely recommend them and wouldn't hesitate to hire them again."

French Drains FAQs, answered by experts

There are several ways to tell if your gutter downspout drain is backed up. The most obvious sign is when you see water flowing over your gutter edges. This can occur during everything from light rain to a rainstorm. Additional signs can include peeling paint around your downspout, visible dirt around your downspout, and moisture on the side of the house. If you're having ongoing problems with clogs caused by a poorly designed or worn-out gutter system, consider getting a quote for gutter replacement cost.

As a general rule of thumb, it’s best to clean your linear drain every two to three months to prevent debris buildup. However, if you notice it draining slowly or an odor from your drainpipes, it’s best to clear the clogged drain and maintain it more often. If you let a clog go for too long, you may have to invest in the price of professional shower drain cleaning, which costs about $225.

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.

Your garbage disposal is not draining because it might have a clog due to food waste, a foreign object, grease, oil, fat, or it may have a broken motor. When water doesn't flush out of the disposal, that's a key sign that your disposal has a clog or needs repair. 

There are a few ways to unclog a toilet without a plunger. Break up the clog with homemade solutions containing soap, vinegar, and baking soda, or simply let hot water spend some time in the drain. You can also use a two-liter soda bottle filled with water to push pressurized water into the pipe to dislodge the debris (see the steps above).
