"I spent a lot of time trying to find someone that could replace my front steps. Getting someone to actually call back was the first challenge. Then, trying to find someone who does everything we wanted: granite steps, faux stone facing and sides, white railings, and the ability to tear up and lower my walkway then redo it to make the first step 7” was an even bigger challenge. We finally found the right guy/company and we are very happy with the results. Walter Santos of W. Santos Construction did it all for us. He started within days of us accepting his proposal. He was kind, communicated the next steps with us well, and the quality was fantastic. I was outside tonight taking photos and a family was taking a walk stopped me to ask who did the steps because “they make the house.” I took some dry and wet pics after the dust was washed off and I’m very happy with the results. He even came out to finish on Memorial Day."

"We had a replacement bulkhead installed and couldn't be happier with the work. The team was responsive and communicative from start to finish. They arrived promptly, completed the job efficiently, and left the site spotless. A few days later, we had heavy driving rain and the inside of the bulkhead stayed completely dry - a true test of quality work! Highly recommend this company for their profesionalism and attention to detail."

"Excellent! The old wooden fence was removed and replaced but we also added a pergola. The installer (Jaime) did a great job and cleaned everything up. He arrived around 7:00 AM and did the job by himself. Very hard worker who was friendly and polite."

Concrete Repair questions, answered by experts

Addressing gaps and cracks reduces heat loss and improves energy use.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

It is possible for a slab leak to cause a sinkhole, but it would have to be a particularly serious leak. A slab leak causes the land under your home to erode and if there is enough movement depressions will form in the ground, potentially causing a sinkhole.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.

Yes. A foundation wall can usually be replaced, but you’ll want to call a foundation professional.
