"We hired Groundworks CA (fka Bay Area Underpinning) for what we understood was a full foundation repair. We paid $42K. They only worked on the rear and never informed us that the front wasn’t included. Months later, while selling our home, a third-party engineer found $189K in unaddressed issues at the front. We were blindsided, lost our buyer, and suffered major financial and emotional stress. Groundworks later admitted they hadn’t measured the front. Their rushed “final inspection” months later felt reactive, not professional. When asked for a partial refund, they refused. We feel misled and abandoned. Avoid."

"Patrick showed up immediately, diagnosed the problems in a no-nonsense way, and fixed them at a price that was FAIR and, frankly, much less than our former plumber who kept coming back to "fix" the symptoms without ever addressing the cause. He is honest, responsive, fair, smart, skilled and friendly. I can't overemphasize- this is your guy!"

"Rich and his crew were fantastic. They went above and beyond in many areas, and were always terrific with communication about all of the aspects of the project. They fully landscaped our front yard, including abundant lighting, and replaced the sprinkler system throughout the property. They were a pleasure to work with and the end product is the envy of the neighborhood."

Drain Pipe Installation questions, answered by experts

Installing a plumbing system is a project best left to professional plumbers. Plumbing systems involve tons of moving parts—water supply lines, pipes, drain lines, sewer connections, and connections to appliances like water heaters, washing machines, and dishwashers. Improper installation of your plumbing system can leave your house vulnerable to potential damages that could result in flooding or damage to your home’s foundation. While you can DIY your way through common plumbing problems like fixing clogged drains or leaky faucets, it’s highly recommended that you contact a plumbing professional for most of your plumbing-related tasks, especially installing the system. 

A clawfoot tub's water supply lines and drain pipe are visible above the floor. When the water leaves the bath, it enters the drain pipe, which leads under the floor, before connecting to the main drain pipe leading to the sewer system or septic tank. Some modern clawfoot tubs also feature an overflow hole and pipe to prevent the bath water from spilling out if you overfill it.

No, rough-in plumbing is one of the last steps before your drywall goes up. This is because essential things like pipe installation require space before other elements go up. After the rough-in plumbing is complete, your inspector will also come to conduct an examination and tell you if your plumbing is approved and satisfies your building permit.

Garbage disposals fit the drains of nearly every sink out there due to universal drain hole sizes of 3 1/2 to 4 inches, but the same isn’t true for the housing underneath the sink. You need plenty of room to fit a garbage disposal under there, so measure the space ahead of time and use those dimensions when shopping for a new model. If you’re replacing an existing model, get one in that size.

Local building codes sometimes require sewer ejector pumps to have their own vents. If so, these dedicated vents run upward through the home and exit through the roof. Otherwise, the pump’s vent pipe can connect to an existing vent stack. Regardless of which method you use, venting is an important part of installing a sewer ejector pump because it helps equalize pressure and prevents gases from building up inside your home.
