"Wonderful contractors. I hired Isaac and Rudy to do a big job for me. Pave a large area around my pool, replaster my pool, and then pour concrete over a separate area in my backyard. Everything looks great, and I couldn’t be happier. Most importantly, they didn’t drop off the face of the earth once payments was made. They took care of me from start to finish and afterwards. I will definitely be hiring them again for other jobs."

"things wet well. Pavers turned out beautifully. Landscaping was beautiful. There were issues over time with sprinkler coverage and with plants or grass that died. Jonathan and his crew (Victor especially) were extremely knowledgeable, took responsibility, was very responsive to issues that arose. I respect that of a company. Things are rarely perfect. Unforeseen issues can arise. It is professional to be responsive, even outside warranty when appropriate."

"They did an excellent job on my backyard concrete. I'm impressed with the professionalism and guidance in helping choose the perfect stamp design."
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.
