All the guys respected my property and left so clean you can't they were here. I highly recommend Alpha Structural for any foundation work you may need"

"The technician arrived at the start of the 2 hour window. On time! Very professional. Explained options for dealing with my toilet leak. I chose to replace the toilet and gave him guidlines for the new toilet. He went to Home Depot, acquired the toilet returned promptly and installed it in a timely manner. After which he broke down and explained the itemized charges. After paying for the work thru my credit card, I received an e-mail summary right away...One major concern that I had in hiring Western Rooter & Plumbing was that their technicians had been vaccinated for Covid 19. I had been referred to Western earlier this year by my condo HOA for a common area leak repair in my unit. I was assured by the dispatcher that the technician coming to my condo was vaccinated against Covid. So when I had this toilet leak problem 6 months later that I had to pay for, out of a multitude of plumbing companies, I went back to Western Rooter & Plumbing after receiving the same assurance."

"**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."

"Our project was one step and a landing on our porch. Approx. 30 sq feet. We had the top layer of tile removed and concrete around the door area chiseled and jack hammered away. They then cut fossil stone for risers and step/landing in large squares as requested. They did put up a moisture barrier at the entrance and calked after grouting the stone. This was done upon the City of Downeys expectations. I believe that wouldn't have been done had I not called the city to come by to clarify the code for this job. So my only complaint is that some workers, actually most don't keep up or research the code. Then when the city does visit you may have to tear down a project and re do it. That can be costly and frustrating. Our porch and step look great. Not sure if the cost to us was cheap, but it is done and looks great."

Foundation Drain Installation FAQs, answered by experts

Costs range from $2,000 to $7,000, depending on system type and excavation requirements.

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.

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.

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.
