"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."

"The estimate was wrong. They did not do everything I asked so then they had to come back and tear walls down for a second time on my dime."

French Drains FAQs, answered by experts

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.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

First, find the cleanout pipe in your yard. Unscrew the cap—you may need a wrench to do so. Then, get a drain snake. You can use a non-motorized one, but a motorized snake will make the job a little easier. Feed the snake through the pipe until it reaches the clog. Spin the snake continuously, but don’t try to feed it through the pipe anymore. Keep spinning until you feel it break the clog apart.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.
