"Great service! We had drain tile installed with a sump pump and a wall braced. I appreciated that the work was done through WAFRP standards. Christian was always very courteous and professional. I would recommend Renew to friends and family. When I had questions after the job was complete Christian offered to come over and take a look to address my questions and make sure everything was good as can be. Great price for the quality work done here!"

"Central Wisconsin Excavating (CWE) did a fantastic job on our project. They built a solid, well-prepared foundation for our 80,000-bushel grain bin and graded our driveways perfectly to ensure water drains away from our buildings. Their attention to detail, quality of work, and professionalism really stood out. The site was left clean and properly finished, and everything was done right the first time. We’re extremely happy with the results and would highly recommend CWE to anyone needing excavation or site work done right."

French Drains FAQs, answered by experts

Yes, you can use hydrogen peroxide to unclog a drain. Instead of using a baking soda and vinegar solution, you can use baking soda with hydrogen peroxide. The process to unclog a drain is the same as with vinegar, but use 1 cup of hydrogen peroxide instead.

While technically possible, it is unlikely that a clogged toilet will fix itself. Clogs caused by water-soluble materials like toilet paper or human waste may eventually break down in the water, allowing flow to resume. However, this can take time, and any clogs from solid objects require manual removal. In most scenarios, especially if you don't have another bathroom, it is best to fix the clog yourself or call a plumber.

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.

Most blockages can be cleared in 1-3 hours, but severe issues may take longer.

If the drain is frozen, the pipes connecting to the washing machine are likely frozen. If the hot water trick doesn’t also unfreeze the washing machine pipes, you can gently apply heat with a hair dryer on the lowest setting. Start at the end of the pipe closest to the faucet to prevent pressure from building in the pipes, and make sure the faucet is open to drain the water as it melts.
