"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"I contacted California Drains because my parent's home was completely backed up to the point where dirty water was coming out from the drains inside and outside their home. They promptly answered and booked me in the same day. They were able to contain the water from continuing to come out of the drains overnight and returned the next day first thing in the morning to get the problem fixed. Price was very reasonable, and the workers were very professional. Left everything clean and drains were completely cleared. It has been months since they came and there has not been an issue since. 10/10 will highly recommend to family and friends."

"As a career woman (currently typing this review while out of town!) with a busy schedule, I needed a driveway that was both beautiful and practical. I needed my driveway redone ASAP and I needed it done fast. Encore Builders made the entire process quick and easy, and the results look GREAT. From day one, Oz and Brandon were professional, efficient, and detail-oriented. They started by taking precise measurements and carefully mapping out the design to ensure the perfect layout. Once the plan was finalized, they got to work by digging up and removing the old driveway, making sure the foundation was properly prepared for the new and improved design. On the next stage, they leveled the ground to create a strong and even base, ensuring proper drainage so I wouldn't have to worry about water pooling in the future. (This is when you know a company is doing its job right). Then came the exciting part--laying the pavers. Their team worked meticulously, aligning each stone perfectly to crea"

"Great! Beautiful straight walls with split face block and topped with brick. Very helpful with ideas for a design that will work with my home, clean, friendly and professional. Also poured driveway and little concrete bridge over a wash at the back of my home with tunnel drain so water still gets through. Highly recommended!"

"Etan Home Construction was a pleasure to work with. Ed, Richard, and crew installed the foundation for our single-family home. Excellent attention to detail and quality of work; Ed caught a discrepancy made by our civil engineer and surveyor, which would have been an incredibly costly error. I could not be happier with the end result, I highly recommend!"

"Impressed! Johnathan and Gio were so professional, courteous, and sympathetic to our situation. I had the unfortunate experience of a root intrusion in my sewage drain and these guys made it right! They worked hard and made sure we still had use of bathrooms during the project. It wasn't the cheapest but when I saw the skill level everyday, I believe I got what I paid for and this isn't something you want to be cheap on when its under the slab! Top notch all around and the attention to detail was commendable, well done guys!"

Foundation Drain Installation FAQs, answered by experts

Installation typically takes 1-2 days, depending on the scope and site preparation.

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.

If you hire a professional, installing a new sewage ejector pump costs $850 to $3,500, or an average of $2,300. Otherwise, if you handle the installation yourself, you can expect to pay $500 to $1,000 for the sewage ejector pump, permits, and other supplies required for this DIY project.

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.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.
