Dunnville is a river town in Haldimand County at the mouth of the Grand River near Lake Erie, known for its annual Mudcat Festival and excellent fishing. The community features heritage homes along Queen Street, established waterfront properties, and a traditional Ontario small-town atmosphere anchored by the Grand River.
Dunnville's location at the mouth of the Grand River near Lake Erie brings cold winters with dual moisture sources from the river and lake, creating challenging conditions for window installations with temperatures regularly below -15C.
Dunnville's dual water exposure from the Grand River and nearby Lake Erie creates persistent moisture that accelerates window deterioration. Many older homes along Queen Street and the riverfront have aging windows that need replacement with moisture-resistant, energy-efficient triple-pane units designed to handle the challenging waterfront climate.

Our riverside home in Dunnville had constant moisture problems with the old windows. Panes installed moisture-resistant triple-pane windows and every problem is solved. No more condensation, no more drafts, and our Grand River home is warm all winter. — Clifford M., Grand River
