"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"Several months ago, I noticed that doors in my house were no longer closing and latching. Specifically, my front door no longer locked completely. Once I got it fully locked I could no longer open my front door anymore, so I knew I had foundation issues. I called Bay Area Underpinning to come look at my foundation and do some measurements. We discovered that my front living room was sinking approximately one and a half to 2 inches. The crew, Lance Sladek, Jake Hall, and Eddie Shaw, crawled under my house and dug 30 to 40 foot holes in the ground to install piers that would lift my foundation. These gentlemen worked in very cramped dirty conditions in 90-100° weather. I was extremely happy with their work and their dedication to doing the job correctly. My after the foundation lift, my front door as well as several other doors in my home were able to close and latch again."

"I am very happy with Harry and his work. We wanted route a gas line, hot and cold water, and a drain to our backyard for an outdoor kitchen. Harry was punctual, did the work to estimate, and the quality of his work is second to no one. He was meticulous to the quality of his work and made sure everything was thoroughly tested before he left. His prices are very reasonable as well (compared with online estimates for linear foot of extending plumbing, his price was better than a general contractor’s that did a bid for the job). Not only did Harry do a great job for our project, I asked him to look at a leaking water heater and he fixed it in minutes. I ultimately will need to replace my tankless water heater and will call Harry when I do. I would recommend Harry to all my friends and family. Harry came highly rated on Home Advisor and he did not disappoint."

"We couldn't of had a better experience working with Pablo at New Earth Landscaping! Estimate process was fast and easy. After reaching out Pablo came by the next day to put together a proposal. He worked with us to stay within our budget. His team does quality work and was ahead of schedule. The whole project was 8 days (2 days ahead of schedule). Throughout the project he kept us updated with good communication. He trained me on using the irrigation system that he installed. At every step he went the extra mile to keep us happy as customers. We love the end results and couldn't be happier with out choice to work with Pablo."

Foundation Drain Installation FAQs, answered by experts

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

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.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.
