"I feel like I had the A-Team working on my driveway project. We had Steve the Field Inspector who identified all the troubled areas. Everything Steve told be about the process, what the team would be doing, and how it would be done. It was all true. When Bryce and Joe showed up. We reviewed the project once again to ensure agreement. The guys got to work. They extended to some drain tile, cleaned out all the cracks, let the polyfoam do its job, and finally sealed all the joints. The result was picture perfect just as I hoped it would be. Thanks Foundation Recovery System team for a great job and a great experience."

"After several years of constantly replacing blown pond lights Bernd evaluated our situation and made a couple of recommendations. Following his recommendation and with his assistance all of our lights were replaced. The pond now glows beautifully from dusk until about 3am. We couldn't be more pleased."

French Drains FAQs, answered by experts

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.

Boiling water helps unclog a drain, but usually only with a harder abrasive such as baking soda or vinegar. On its own, it isn’t the most effective tool. In addition, you shouldn’t use boiling water if you have PVC pipes, as it can soften or melt them. Use a plunger or enlist the help of a pro if you have plastic pipes.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

If you drop jewelry down your sink, it can cause a clog, especially if it accumulates other debris on its way down. However, that is the least of your worries if you drop your favorite jewelry down your drain. If your gold band goes tumbling down the sink drain, don’t panic—refrain from running more water down the sink, and follow the steps above.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.
