"As others have said here on Home Advisor, Vincent and his wife Grecia do outstanding work, communicate better than any other contractor I've ever hired, and most importantly to me they are quality people. The price was fair and reasonable; they were flexible and super trustworthy. I actually enjoyed having them at my home believe it or not. We needed to tear up an old concrete driveway (~50' x 12') and replace it. Initially we thought we were going to go with asphalt because of the lower cost, but when we discussed the pros and cons with Vincent and compared his quote to those from other companies, we realized AA Outdoor could do a high quality concrete driveway at a price that was comparable to asphalt. Concrete will also save us maintenance and expense over asphalt too, and that decision was made in part because of the excellent communication and feedback from Vincent when we first started discussing the project. Vincent is very knowledgable and has decades of quality experience; I asked a ton of questions and he answered them all - I actually learned a lot from him. I recommend Vincent and Grecia (AA Outdoor Services) highly without a doubt!"

"Overall,pleased with the experience. Two very hard working men did a good job. The only negative was when they left concrete dust from a saw in the garage. What a mess."

FAQs for concrete work projects in Cos Cob, CT

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.
