Decks Engineered for Central New York Winters
Central New York is tough on outdoor structures. Between heavy lake-effect snow, ice buildup, and dramatic temperature swings, a poorly built deck will not last. Ontario Builders constructs every deck with the local climate in mind — using deep concrete footings that extend below the frost line, galvanized and stainless steel fasteners that resist corrosion, and lumber that is rated for ground contact and sustained moisture exposure.
We also offer complete deck restoration and staining services for homeowners who want to bring an aging deck back to life without a full rebuild. Our deck staining process includes power washing, sanding, and applying commercial-grade stain that penetrates deep into the wood grain to protect against UV damage, moisture absorption, and mildew growth. A properly maintained deck in Mexico, NY can last 25 years or more — and Ontario Builders makes sure yours is built and finished to reach that benchmark.
Whether you need a brand-new deck, a front porch rebuild, or professional staining for an existing structure, our team delivers the same level of precision and attention to detail on every project.

Deck Construction FAQs
Pressure-treated lumber is the most popular and budget-friendly choice for Central New York decks. It holds up well against rain, snow, and freeze-thaw cycles when properly sealed and maintained. Composite decking is a premium alternative that resists warping, rotting, and fading without the need for annual staining. Ontario Builders helps you choose the right material based on your budget, style, and how much maintenance you want to do. We will walk you through samples and real-world examples so you can see and feel the difference before committing.
Most deck projects take between 1 and 3 weeks depending on the size, design complexity, and weather conditions. A standard single-level deck typically takes about one week from footings to finish, while multi-level builds, wraparound porches, or projects requiring extensive concrete work may take closer to two or three weeks. Ontario Builders provides a clear timeline during the estimate process so you know exactly what to expect. We also communicate daily throughout the build to keep you informed of progress.
In most cases, yes. The Town of Mexico and most Oswego County municipalities require a building permit for new deck construction, especially for decks that are attached to the home or elevated more than 30 inches off the ground. Ontario Builders handles the entire permitting process for you — from submitting the application and site plans to scheduling the required inspections. Everything we build meets or exceeds local building codes so you never have to worry about compliance issues down the road.
