"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."

"I had a consultation with Brandon and Oz to install artificial turf by my sidewalk. I am very pleased with my consultation. Oz was able to come out and give me a quote right away. The quote that he gave me was very reasonable. He was very professional and nice. Encore builders appears to be a very well established company and I am very happy with the quote that I received. I will update my review once I move forward with the work."

"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

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

A grinder pump is a major investment for homeowners and business owners alike. Protect this investment by choosing a reliable and reputable contractor to source the pump itself, install it, and outsource any additional work. Research local sewage system contractors ahead of time to ensure they have the appropriate insurance and licensing. You should also perform a fairly thorough online search to get a feel for the company’s professionalism by reading reviews.

Finally, give them a call to discuss the project. A good technician will be more than happy to get into specifics regarding both the installation process and the pricing.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
