Built Tough for Delaware County Weather
Engineered for Ohio's Four Seasons
Delaware sits right at the edge of Central Ohio's snow belt, making durable deck construction essential. We engineer every project with deep footings below the frost line, pressure-treated or composite framing, and weather-rated hardware that withstands heavy snow loads and the brutal freeze-thaw cycle. Your Delaware deck will look great and perform flawlessly for decades — guaranteed.
