"I recently hired EA Masonry to install a shed base and expand my concrete patio, and I couldn’t be happier with the entire experience. Their pricing was very competitive, but what really stood out was how incredibly friendly and welcoming they were from the very beginning, I felt comfortable with them right away. The quality of their work was phenomenal. They were professional, detail-oriented, and clearly take great pride in what they do. It’s rare to find a team that combines skill, reliability, and such genuine kindness. I highly recommend them to anyone looking to hire for a project. In fact, I already have another project for the Spring that they will be returning for!"

"Gary Gagne repaired and refurbished my concrete steps and did an excellent job. They look better than new!! He responded to my inquiry almost immediately , got me an application for a contract and set up an appointment to get the work done very quickly. He is insured and local and has been in business for over 20 years. He has a website with pictures of projects large and small in all his many categories. He took good care of my siding and windows as he sprayed on the steps finishes, covering them with paper and did an excellent job cleaning up after the job was done . He is a top notch professional in every way and I am so happy to have found him. I very highly recommend him."

"I spent a lot of time trying to find someone that could replace my front steps. Getting someone to actually call back was the first challenge. Then, trying to find someone who does everything we wanted: granite steps, faux stone facing and sides, white railings, and the ability to tear up and lower my walkway then redo it to make the first step 7” was an even bigger challenge. We finally found the right guy/company and we are very happy with the results. Walter Santos of W. Santos Construction did it all for us. He started within days of us accepting his proposal. He was kind, communicated the next steps with us well, and the quality was fantastic. I was outside tonight taking photos and a family was taking a walk stopped me to ask who did the steps because “they make the house.” I took some dry and wet pics after the dust was washed off and I’m very happy with the results. He even came out to finish on Memorial Day."

FAQs for concrete patios, walks & steps installation projects in Londonderry, NH

Most sidewalks rely on a ready‑mix blend of Portland cement, sand, gravel, and water that trucks deliver to your site and pour in one continuous lift. For added strength, many contractors fold in fiber mesh or steel reinforcement. This mix cures into a rock‑solid slab that stands up to foot traffic, freeze‑thaw cycles, and daily wear for decades. Expect a pro to recommend a 4‑inch‑thick pour for standard walkways.

With the right mix, proper drainage, and routine upkeep, a concrete sidewalk can last 25 to 50 years. Freeze‑thaw cycles, road salt, and heavy loads all shorten that timeline, but sealing every few years and patching small cracks early keeps damage in check. Think of sealing as inexpensive insurance for decades of safe, stable footing. In milder climates, some slabs push well past the 30‑year mark without major repairs.

Concrete sidewalks crack as a result of significant temperature fluctuations and heavy load pressures. The freeze-thaw cycles and sustained weight from vehicles or intense foot traffic force the concrete to develop cracks over time. Applying a premium sealant every two to three years and substituting salt with sand for de-icing minimizes crack formation. Regular maintenance and timely repairs safeguard the sidewalk’s structural integrity and extend its service life.
