"These guys are excellent craftsmen, very conscientious and detailed in their work, professional in every way. We had some older brick and concrete steps removed and replaced with brick and granite. It came out beautiful! Having them back to replace the walkway, too."

"We are very pleased with Leo and his team. They replaced our old concrete walkway with a beautiful stone and brick walkway. They were so professional, talented and turn around time between the free quote and the project being done was about a month. Highly recommended"

"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!"

"The owner of this company was wonderful to work with. He guided us in the right direction, he was always on time and hard workers. They removed an old stone wall, hauled it out and replaced it with a beautiful stone wall. They did such a great job we are having them replace a smaller wall to match the new one. If you want a good job done I highly recommend this company. I don't think you would be disappointed."

"Working with Brett to replace our front steps was an easy, straightforward experience. The estimate he provided was accurate and when we asked for extra work to be performed we were accommodated within the regular project timeline. The services he provided exceeded our expectations using quality materials and leaving no trace of discarded project materials behind. We are very happy with the results. Thank you!"

"Edwin and his team did an outstanding job on a challenging retaining wall project. He was very collaborative in working out the layout of four retaining walls with eleven granite stairs and a new patio with a fire-pit. His team worked very hard with the excavation and construction which was all done by hand due to the slope of the site. He started and completed the job as quoted. We are pleased with the finished result."

"I interviewed several landscaping and masonry companies to install a new paver walkway and demo my existing brick steps to install new granite steps.. I decided on S.L. Dionne Landscaping and I couldn't be happier. Shawn and Bob were both knowledgeable, professional and worked efficiently. Both possessed great attention to detail to the project at hand. At the end of each work day, the property was left clean and orderly with all tools put away for the night. The finished product was far beyond my expectations. Several people driving by my home have stopped to comment on the transformation of the front of my home All who stopped admired the the quality workmanship and said how beautiful the job came out. I would definitely hire SL Dionne again and will do so for my future projects. Thank You Shawn and Bob.. Lynne Allen Plaistow, New Hampshire"

FAQs for concrete work projects in Sandown, 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.
