"It went flawlessly. The three guys arrived on time and made fast work of disassembling our granite slab front steps, by hand. They created a new reinforced base with crushed stone and reassembled the slabs to a new level surface. They patched two concrete retaining walls. Then the attacked the 37-year dirt build-up on our large concrete patio. They cut and filled a few large cracks and pressure washed the surface so that it now looks like a completely different patio. I could not be happier with the completed results of these three too-hard-for-us projects. Excellent work by three very hardworking professionals!"

"JJ Sousa is my trusted mason for any all indoor/outdoor work. They can do so much more than just masonry as well! Recently they came up with a great design for a 40â granite outdoor staircase and a large outdoor patio with natural earth stones. They also solved a lot of drainage/flooding issues I was having! I highly recommend them for your next job. They go above and beyond for their customers!"

FAQs for concrete work projects in Alton Bay, NH

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.
