How are costs calculated?
Costs depend on materials (brick, natural stone, manufactured stone), project size, complexity (weather exposure, drainage, slope), and local conditions. We provide free, detailed estimates for every project.
How long will my masonry job take?
Smaller jobs (brick repair, repointing, small feature work) often take a few days. Medium size residential jobs (patios, walkways) may take 1-2 weeks. Larger commercial works take more time — we’ll give a realistic timeline before work begins.
What materials hold up best in Lake Ronkonkoma winters?
We recommend frost-resistant bricks, bluestone or other dense stones for veneers, high-quality mortar mixes designed for freeze/thaw, and good drainage to avoid moisture retention.
What warranty or guarantee do you offer?
We stand behind our work. Our workmanship is guaranteed, and we help clients with aftercare tips, maintenance, & inspections to keep things strong season after season.
