East Greenwich is where Cornerstone is based, with our office on Post Road. Since 2022, we have served local homeowners with deck construction, siding installation, roofing, carpentry, renovations, and related general contracting services.
We regularly handle permit applications for our projects and understand the importance of complete plans, product information, and clear communication with local officials. As a woman-owned Rhode Island contractor, we approach every East Greenwich project with careful planning, dependable service, and respect for the homeowner’s property.

Custom deck construction is our most requested service in East Greenwich. We build single-level decks, multi-level decks, wraparound decks, decks with pergolas, and pool surrounds using Trex and TimberTech composite decking. We have tested both across enough Rhode Island winters to know how they hold up. We handle the permit process with East Greenwich Building and Zoning on every project, including properties in the historic district that require additional review.



Being based in East Greenwich gives our team practical familiarity with the town’s homes, permitting requirements, coastal conditions, and historic character.
Projects that require permits need accurate plans, product specifications, and property information. Cornerstone prepares and submits the documentation required for our permitted work and keeps homeowners informed throughout the review process. Approval timing varies by project type and the town’s current workload.
Exterior work within or near a historic district may require additional documentation or review. We help homeowners identify applicable requirements and assemble project information such as photographs, material specifications, and proposed profiles when needed.
East Greenwich includes waterfront properties, historic homes near the village, established neighborhoods, and newer homes west of Route 2. Each setting can present different considerations for materials, moisture exposure, access, and exterior design.
We regularly prepare permit applications for our work and communicate with the appropriate local departments when review is required. Requirements and review times vary, so we confirm the process for each property and project rather than making one-size-fits-all promises.
Homes closer to Greenwich Cove can face wind, salt, and moisture exposure. Material selection, corrosion-resistant fasteners, flashing, and drainage details should reflect those conditions.
Older East Greenwich homes may require careful evaluation of existing sheathing, trim profiles, ventilation, and water management before exterior work begins. We document concealed conditions and discuss options before additional work proceeds.
When permits are required, we coordinate the project information needed for submission and keep the homeowner updated during review. Construction begins only after applicable approvals are in place.
