AW Waterproofing Solutions calls Napanee home. We're the local waterproofing specialists that Greater Napanee homeowners have trusted for over 15 years. From foundation crack repair to full exterior Duraflex waterproofing systems, we know Napanee's soils, weather, and home foundations better than anyone.
Greater Napanee sits on clay-heavy soil throughout Lennox & Addington County. This clay expands when saturated and contracts during dry periods, generating significant lateral and hydrostatic pressure against foundation walls year-round. Combined with Ontario's seasonal freeze-thaw cycle, this pressure forces water through the smallest foundation crack or joint in a foundation wall.
Spring snowmelt from the Napanee River watershed raises local water tables dramatically each year. Homes near Napanee Creek, the river flats, or low-lying areas of Greater Napanee face repeated flooding pressure below grade. Many homes in Greater Napanee were built between the 1960s and 1980s — meaning original waterproofing membranes, parging, and weeping tile systems are at or well past their expected service life.
Water doesn't just cause inconvenience. Left unchecked, wet basement moisture causes mould throughout wall cavities and HVAC systems, structural deterioration of foundation materials, framing rot when water reaches wood, and reduced property values. The earlier you address it, the less it costs to fix permanently.

"We've lived in our Greater Napanee home for over 20 years and always had a damp basement in spring. AW Waterproofing came out, assessed the foundation, and installed an interior waterproofing drainage system that's kept us completely dry through two wet springs. We wish we'd called sooner."
"The crew was professional, clean, and explained everything before they started. Our 1970s bungalow had hairline cracks in the foundation wall that were letting in water every year. Polyurethane injection sealed them completely. Excellent local company."
"We had exterior waterproofing done last fall — full excavation, Duraflex membrane, new weeping tile. The team finished on schedule and the yard was restored properly. No more water, no more worry."
