"Sebastian & Ableardo and crew were wonderful they were by far the most affordable. They gave me a bid to replace my old concrete patio and fix a crack sidewalk which I ended up having them replace another part of my sidewalk it became a bigger job then expected, when I had a question Sebastian got back to me right away. They had the job done in 2 1/2 days in this heat. I would highly recommend them my dad is going to call them I already passed there business cards out to some friends. Thank you Q&M LLC"

"Mike provided an estimate and plan that worked within my budget. He monitored his crew, and they completed the work promptly. Mike was professional, and the team was friendly. When I discovered later that some of the plants had died or were not thriving, I called him, and he made arrangements to return a week later and personally replaced the plants."

"JDM is one of the best contractors I've ever worked with. They are my go to for all concrete works and I've used their services extensively. A 70'L x 12' tall 2'thick Keystone retaining wall with 2 bends, footings, a 100' sidewalk curb, 1200 sq feet of crushed stone leveling and ground prep. Thousands of sq feet of landscape grading. They've been been spot on every time. For example, the retaining wall, has both low point drainage and face drains, with stepped geogrid tiebacks. This is how a proper retaining wall is done. They even trimmed the geogrid fabric around the blocks 100% pro grade retaining wall. Get complimented on it by other contractors all the time. Footings were 2'round and 1'round dug 4' deep, well below frostline, positioned right on center for steel posts. Ironworker gave a "dang, these footings are dead nuts". The concrete walk had 2 vectors of fall, 2% linear fall and 1% lateral. There are relief scores every 6' and its edges properly shaped against chipping. Obviously mother nature doesn't play nice and poured concrete does its thing, so I bet I could bust out my micrometer and laser level and find some +-% somewhere, or some place where concrete leaked through forms. Its real life and poured material doesn't always obey. I read some bad reviews here and I must say, am surprised. If you communicate to Danelle and Melvin what you want done EXACTLY they will get it done to your speciifications as close as anyone I've worked with. Danelle shows up on time to do the estimates, bids are quick and fair, and the invoice has always been at or below bid. Melvin is a top tier foreman. Asks what you want before every job. He does exactly what you say, so some of the negative reviews could probably have been more thorough with their instructions. Specify depth, degree of fall, give them the architectural prints. You will get what you want. If you want precise results, give precise instructions, and JDM gives me the results I want every time, bar none. I'll build my retirement home on their concrete."
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.
