"Capped an old water connection in my laundry closet and closed it into the wall, as well as changed the connection box around the drain hose to make it more flush with the wall. Looked like the water connection was never there when they got done with it, and the connection box/drain hose looked great as well. Definitely recommend!"

"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."

"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."

Customers say: True professional

"We are thrilled by the results! Mike and his crew took out 10 boxes of dirt from a hill in our back yard all manually! They then installed a 50 x 4ft retaining wall (fully permitted) on the hill. After that poured a 60 x 10 concrete deck and steps to our new upper deck that now overlooks the pool. They then covered the new wall and existing lower wall with new custom colored stucco. We have now doubled our backyard space and for the first time in 12 years be proud to show off our backyard!

Foundation Drain Installation questions, answered by experts

Grinder pumps alone cost $300 on average. The average cost to install a new grinder pump is between $2,000 and $4,000, including the pump and labor. This price can also change based on the exact type of grinder pump you choose, labor costs in your area, and the power system your home currently has.

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 move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

The cost to install a new sump pump, including materials and professional labor, typically ranges from $1,000 to $3,000. The average cost is often cited between $1,200 and $2,500. Several factors influence the final price, including the type of pump, the complexity of the drainage system, and the installation location. For instance, installing a sump pump in a basement may cost around $1,200, while a more complex installation in a crawl space can cost an average of $3,900. It is important to hire a licensed professional for the installation to ensure quality work, which can impact the pump's lifespan and warranty. Note that these costs are for a new installation; replacing an existing unit is less expensive, typically costing $308 to $748.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.
