"Alpha Structural are class acts 100%. Dick came to my house, gave us an honest estimate under what we had expected and got us on the books promptly to begin work. The foreman, Jose, was attentive and polite throughout the work. The stars of the show, Lawrence and Antonio, blew us away with their work. They gave me regular updates and got the job done, start to finish, with utmost professionalism. Little things, like pulling in my garbage cans after collection, just really made their work ethic and politeness stand out. With their stellar reputation and amazing performance, I trust this company with any foundation work I'll hopefully not need in the future! I just wish they provided more services so that I can work with them more."

"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."

The installation process was seamless and the team was professional and efficient. I now have a backyard that I can be proud of and enjoy all year round. I highly recommend this company for anyone looking to enhance their outdoor space."

"**SIMPLY OUTSTANDING** Robert Garcia Concrete is the only company, in the past 3 yrs that we hire. During this time, Robert and his crew have completed 3 jobs for us. Everything from our first conversation about the upcoming project is fully estimated in detail and documented in both email and text by Robert. His attention to customer service is beyond compare. The cost is very fair. The level of perfection that the entire crew puts forth is really enjoyable to witness. Our most recent project was a concrete patio replacing a preexisting. wooden deck that, over the years was in disrepair. Robert and his crew demo'd the structure in short order, leaving a clean area. The next morning they installed rebar and forms. The next day they were here bright and early w/ concrete pump, truck, and in no time had the new patio slab looking fabulous. Robert himself, always returns the following day to remove forms, and check to ensure all is well. An impressive part of this project was the replacement of a small narrow set of precarious stairs with risers that were too high and too shallow. They completely transformed the area by removing the old, and made all new safe and aesthetically symmetrical entry to our family room from the backyard patio. These guys are top shelf! Friendly professionals. And...they play great music while they work, which makes watching the evolution to the area that much more enjoyable."

Foundation Drain Installation FAQs, answered by experts

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.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

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.
