"Henry was very professional and also made me feel comfortable explaining what my concrete needs were. The work was performed perfectly and exactly to my expectations . The work was done soon after the estimate was given and I thought that was amazing seeing it is the season that everyone is looking to have their jobs done . I would highly recommend Republic Masonry to anyone looking for concrete work ."

"We are very pleased with Leo and his team. They replaced our old concrete walkway with a beautiful stone and brick walkway. They were so professional, talented and turn around time between the free quote and the project being done was about a month. Highly recommended"

"Tomas and his crew did excellent stone veneer and concrete repair work. They arrived as promised and completed the work quickly. They kept the worksite clean and clean up after themselves. The price was competitive for the project. Hilarios construction was a pleasure to work with."

"08-AUG-2025 Issues began immediately after hiring Pro Foundation & Masonry. During the estimate, I told Foreman Bobby there was no mortar in the cinder blocks. He gave a quote that I believed included proper mortar. On Aug-12-2025, I raised the issue again?he said he was ?focused on the damaged area.? When digging, a missing footing section was found, and Bobby quoted $22,500, which I thought was too high. Though he fixed some cracks, major ones in the cellar were ignored. They used the wrong mortar (not S mortar as discussed) and left sloppy drippings inside the wall. I sent photos on Aug-23; Bobby replied on Aug-25 saying the floor was dirt. Promised cleanup on Aug-30 never happened. I followed up repeatedly?no one came. They even left a dangerous cinder remnant that I tripped on. A section of wall was filled with concrete instead of block?looks unprofessional. They say one thing, do another. I?m very unhappy with their work and service. They're gonna fix the two crack on my fieldstone foundation. The manager Rey came and he felt really bad that the foreman left in this way they left it. He was really pretty readsonable."

"Perfect! The removal of the pre-existing concrete patio took and entire day of hard work with some heavy equipment and lots of muscle. Once the old concrete was removed and disposed of, the site was excavated to prepare the underlying base of crushed stone and sand for the pavers. The paver installation went well, but required last minute cutting into small pieces to fit some difficult spots (around the cellar hatchway). Everything looks beautiful compared to the older poured concrete. We're totally satisfied with the project and the team who did the work!"

"AC Stoneworks were awesome! We had them build a paver patio for us. Their pricing is very reasonable and they were responsive, efficient, and friendly. They suggested some excellent ideas during the quoting phase, and were happy to make some adjustments during the work phase. Great to work with!"

"These guys are the best. You donâ t need to look any further. They came out to assess the issue the same day. Within two weeks they had manufactured new concrete footings in the basement, placed new lally columns and removed the really old ones. Highly recommended."

Figuring out how many bars you need isn’t a one-size-fits-all equation. A structural engineer or experienced concrete contractor will look at your slab’s thickness, the loads it must carry, and local code requirements, then run the numbers for you. That quick consultation protects your budget and keeps the finished slab safe, level, and up to code.
Match the metal to the job. For light, thin pours like a sidewalk, welded wire mesh often does the trick. Thicker slabs—driveways, garage floors, foundations—usually call for traditional steel bars. If your site sees salt, humidity, or coastal spray, spend the extra cash on galvanized or stainless steel to fend off rust and avoid future repairs. When in doubt, a concrete pro can confirm the best fit for your project and budget.
Stainless steel costs more up front, but the alloy can last 75 years or longer with little to no rust. That longevity means fewer repairs, less maintenance, and peace of mind for structures exposed to salt, moisture, or de-icing chemicals. If you’re pouring near the coast or in a humid climate, the extra dollars now can save you multiple replacements down the road.
An engineer will review the slab’s thickness, span, soil conditions, and expected loads, then specify bar size, spacing, and grade. Skipping that step or guessing can leave you with cracked concrete or a blown budget. For a modest consultation fee, a local engineer or contractor can do the math and hand you a rebar schedule that meets code and keeps your project on solid footing.
