"We were in a tight time crunch to get patio walls and concrete steps repaired because we were told our pool area ground prep was starting the next day. I listed my project and heard from 3 Brothers Masonry within 20 min. They arrived 2 hours later and gave us a quote. We agreed and they came back and finished the job that same afternoon, as agreed. We appreciated the quick response, the appreciation of our time constraints, and the timely completion of our repair project, as quoted, both in workmanship and price. We highly recommend them!"

As a highly skilled framer and carpenter with eight years of dedicated masonry experience, I bring a rare and comprehensive understanding of structural development to every project. My background blends the precision of finish carpentry and the durability of robust framing with an extensive mastery of concrete, stone, and brickwork. This unique dual expertise allows me to seamlessly bridge the gap between foundational masonry and structural woodwork, ensuring structural integrity, exceptional craftsmanship, and efficient workflow management from the ground up.

The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Rick responded immediately to my e-mail inquiry through the website and called me to set up an appointment.  He was extremely professional, courteous and knowledgeable.  As it turns out, after making the arrangements for the sump pump, we discovered the source of our water was from our heating system.  When we informed Rick of this and the fact the sump pump would not be needed, he promptly refunded our deposit.  I would definitely recommend Rick Jackson and will contact him in the future if the need arises.

FAQs for concrete work projects in Keene, 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.
