"The technician arrived at the start of the 2 hour window. On time! Very professional. Explained options for dealing with my toilet leak. I chose to replace the toilet and gave him guidlines for the new toilet. He went to Home Depot, acquired the toilet returned promptly and installed it in a timely manner. After which he broke down and explained the itemized charges. After paying for the work thru my credit card, I received an e-mail summary right away...One major concern that I had in hiring Western Rooter & Plumbing was that their technicians had been vaccinated for Covid 19. I had been referred to Western earlier this year by my condo HOA for a common area leak repair in my unit. I was assured by the dispatcher that the technician coming to my condo was vaccinated against Covid. So when I had this toilet leak problem 6 months later that I had to pay for, out of a multitude of plumbing companies, I went back to Western Rooter & Plumbing after receiving the same assurance."

"This was a difficult project, owing to the no-cripple-wall construction of my house and the ridiculously tight crawl space - less than a foot in critical spots - plus the maze of beams and ducts. I called six or seven plumbers to come out and bid the work and two of them ran screaming (well, not really, they just told me they needed to work up an estimate 'back at the office' and never called back). One guy swore I'd have to rip out a wall AND the floor to get to the pipe. Mr. Rooter didn't propose anything so dramatic. They just said they'd excavate as needed to make room to move around. So that's what they did. They billed it as a two-day job. They showed up on time, and the work was wrapped up by the third hour of the second day. Because that, I was concerned this job had been overbilled. Their bid had been astronomical, but it was still lower than everyone's except the guy with the lapsed bond. Mr. Rooter had been willing to negotiate and I knocked about $650 off their initial bid. They took another $200 off at the back end because of my concern with overbilling. They didn't have to do that since they had a signed contract in hand, but they were willing to take care of a customer. Thumbs up for that. The work looks solid, as far as this layman can tell. Everything drains as it should and none of the joints leak."

"Fantastic experience! Jerry Flores, and Flores Construction replaced a damaged concrete wall in two days. They were quick, efficient professional and personable in every way. Their pricing was very reasonable and they checked with me every step of the way to be certain they were meeting my expectations. I’m already working with them on another project. I would recommend them without hesitation."

Foundation Drain Installation FAQs, answered by experts

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.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

DIY is possible for small systems like French drains. Professional installation ensures proper grading and long-term effectiveness.

Basement toilets don’t always need a pump. However, it is the most common setup because plumbing systems use gravity to move waste away from the home. Basement toilets often sit below the home’s main sewage system, and installing a sewage ejector pump pushes the wastewater and sewage up to the main sewer line. Alternatively, you can use an upflush or macerator toilet that breaks down the waste and pushes it straight to the main sewer line rather than via a sewer line from the bathroom.

The regulations around whether drain pipe installers need to hold licenses or certifications differ based on where you live and the type of drain pipe installed. Municipalities have varying rules and regulations about who can and can’t perform plumbing work. However, we recommend hiring a certified plumber to install or modify your drain lines. Licensed plumbers will perform a high-quality, professional installation, which translates to a lower risk of clogs and leaks in the future. Use Angi’s state licensing tool to confirm the license status of your potential plumber before hiring them to install your drain pipe.
