"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. 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."

"I hired Groundhog Landscaping for general weed and feed service for my lawn. Their machine leaked gasoline all over my lawn. They came out to “fix” my lawn and made a repair. Meanwhile they are sending me a bill for the service they performed. I told them I would not pay it until the lawn was fixed. 10 weeks after they have not fixed my lawn and it is a complete mess. Please see the pictures"

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