"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."

"????? If I could give zero stars, I would Hiring this contractor was a nightmare from start to finish. The bathroom they delivered is so poorly done that I feel like I need to redo it entirely. They rely on subpar subcontractors with no professionalism or craftsmanship. ? Overpromise and underdeliver: I had to stay on top of every detail myself, doing the job the contractor was hired to manage. ? Unreliable: Never kept appointments or confirmed schedules. The only time they showed up on time was to collect payment. ? Unsafe practices: At one point, a subcontractor was cutting concrete inside the bathroom with a gas?powered tool, filling my entire home with smoke. I had to intervene to stop it and argue just to get basic protections like tarps in place. ? Poor management: Subcontractors openly complained about not being paid, and I even had to send one home myself because of unacceptable behavior. ? End result: Substandard work that does not reflect the money spent. Save yourself "

"We had a replacement bulkhead installed and couldn't be happier with the work. The team was responsive and communicative from start to finish. They arrived promptly, completed the job efficiently, and left the site spotless. A few days later, we had heavy driving rain and the inside of the bulkhead stayed completely dry - a true test of quality work! Highly recommend this company for their profesionalism and attention to detail."

FAQs for concrete patios, walks & steps installation projects in Amherst, 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.
