About Green Bay & Why Our Work Lasts Here

Green Bay averages 51 inches of snowfall per year, and the freeze-thaw cycle that follows each winter is one of the harshest tests any deck can face. Moisture works into wood grain, expands when it freezes, and splinters what was a smooth board by spring. That’s why we recommend composite decking — Trex and TimberTech products are engineered specifically to resist moisture absorption and handle thermal expansion without warping.

For homeowners in historic neighborhoods like Astor Park and near the Allouez border, where homes are 100 years old or more, we pay special attention to ledger attachment on older framing and ensure our footings reach Wisconsin’s required frost depth. On the East Side and in Preble, newer builds allow for cleaner connections, but the climate demands are the same. Every deck we build in Green Bay is designed to still look right in year ten, not just year one.
