Costs depend on the scope and what we find under the surface. Fence and gate builds are often priced by linear footage, while porch or stair rebuilds depend on framing, footings, and finishes.
Simple installs can take a few days. Structural rebuilds can run longer, especially if we uncover rot or need extra drying time after removal. We give a realistic timeline before we start.
Spring through fall is common because of consistent temperatures and easier curing conditions. That said, we also schedule around your needs and the specific materials being used.
Pick a team that explains the build approach, calls out moisture and structural risks, provides a written scope, and gives you clear expectations on timeline, access, and cleanup.
