"They did a great job. The job took 2 days, over a week, to allow the concrete to cure. The back corner wall of my foundation was leaning out. They jacked up the house and rebuilt the foundation. The crew were nice and kept the work site clean."

Customers say: Quick response

"Contacted Mike after waiting for the original plumber we called to cal back (never heard from him) . My daughter told us about My Guy had plumbed their bathroom. Mike told us he would be in Spokane on the 10th of March and that he could do a laundry room sink install in the afternoon. We sent him pictures of the old sink and the plumbing set up. He arrived as promised with all material in hand and within 4 hours he and his apprentice completed the job. The completed project was far better than we had ever hoped for. They did a total cleanup and removed the old concrete sink and did it all at a reasonable price. We would not hesitate to recommend Mike for any plumbing job."

"We had a complicated job to widen a basement walkout, which included demolition of walls and steps that had been improperly installed. We also wanted other steps and a patio demolished and new steps and patio poured, as well as sidewalks. We got bids from several contractors who were willing to do the job but seemed not to necessarily know what they were doing. Chris Ferraro gave us a bid, and we knew right away that he knew what he was doing and would do a quality job. It wasn't cheap, but it was well worth it to have the work done right and look great."

Foundation Drain Installation FAQs, answered by experts

Yes, you can install a sump pump yourself. By following the steps above, you can have a sump pump installed in 24 hours. You will have to use some advanced tools and techniques, so if you feel uneasy about taking it on yourself, it’s best to hire a professional.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

No, you can’t drain your sump pump into your home’s sewer system. In fact, it’s against the law in many places because dumping extra water into a municipal water system can disrupt or overwhelm the treatment process. And for similar reasons, you shouldn’t discharge a sump pump into your septic system, either.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.
