Decorative Overlays, Stamped & Colored Concrete

Upgrade entries and outdoor living with stone, slate, or board-form looks. UV-stable sealers resist sun fade and make rinse-down cleanup quick for properties in Brooklyn, Canterbury, and Plainfield.

Moisture Vapor Barrier (MVB) & Professional Surface Prep

We moisture-test every slab. Where vapor drive is elevated (common in older basements and low-lying sites), we install 100% solids MVB. Industrial grinding/shot-blasting plus crack/joint rebuilding ensure long-term adhesion.

Windham County FAQs

Do coatings handle the winter sand and salt along I‑395 and Route 44?

Yes. Windham County roads are heavily sanded and salted in winter. Our epoxy and urethane systems use chloride-resistant resins and tough topcoats to stand up to abrasives and de-icing chemicals. A light rinse in late winter or early spring helps extend the coating’s lifespan.

Is moisture a concern in older basements and mill buildings here?

It can be. Many historic homes and repurposed mills in Windham, Putnam and Killingly sit over high water tables or have minimal vapor barriers. We moisture-test every slab and, when readings are elevated, apply a 100 % solids moisture vapor barrier to prevent bubbling or delamination.

Do you work on barns and agricultural shops in rural areas?

Absolutely. The Quiet Corner has numerous farms and equestrian facilities. We install slip-resistant coatings for feed rooms and stalls, full-flake systems in garages, and heavy-duty resurfacing in workshops. These systems hold up to tractors, skid loaders and constant hosing.

Do I need a permit for coatings or resurfacing?

Interior coatings generally do not require permits. New exterior slabs or structural changes may—requirements vary by town (e.g., Windham, Putnam, Killingly). We’ll review any permitting questions during your estimate.
