"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."

"Mike did an excellent job. He was very attentive to my concerns regarding the fill valve issue I've been having with one of the Toto toilets they installed. I am very satisfied with the resolution. Mike just reenforced my decions to use Valley for all my plumbing needs."

"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 had 5 different plumbing contractors look at my needed repair. They all had basically the same solution and high costs. Harry looked at the problem (repairing and installing 80ft of copper plumbing from the main to my house) and came up with a completely new and better solution at a lower cost. Harry was diligent and responsive and truly cared about a quality outcome and a sound repair. I would highly recommend Harry for all your plumbing needs."

"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

Heavy rain can affect a leach field because the extra rain can cause the groundwater level to rise. This leads the soil around the leach field to become saturated with rainwater, so it’s no longer able to take in effluent from the leach lines for final treatment. Heavy rainfall can cause the leach field to flood.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

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

Gravity can make it difficult to make plumbing work in a garage if your plumbing is lower than your drainage point. Fortunately, there are ways to create drainage when adding a bathroom to a sunken garage. Plumbers will recommend using an upflush system that discharges into a pump from the back of the toilet.

Almost any kind of home can have a wine cellar or cabinet installed. You’ll need an area where a concrete floor can be put in, along with the necessary insulation, climate control, and ventilation systems. If you think of yourself as an aspiring sommelier, an underground wine cellar may be ideal, but it will cost significantly more. 

What you choose to install really depends on your budget and how many bottles you’re looking to store.
