Stittsville sits at Ottawa’s western boundary where the prevailing Ottawa Valley westerlies are strongest in the suburban area, and west-facing entry doors in Stittsville lose their weatherstripping effectiveness faster than comparable sheltered Ottawa urban entries. The village core homes have seal profiles from multiple eras of modification. The Fernbank builds have seals that are approaching their first replacement. We replace weatherstripping across all of Stittsville the same day.
The prevailing westerlies that Ottawa Valley residents know well strike Stittsville’s west-facing entry doors with more sustained force than comparable entries in sheltered Ottawa urban locations. The wind pressure differential across a closed west-facing Stittsville entry door in January is measurably higher than on a sheltered Centretown entry — and that pressure differential is what determines whether a weatherstripping seal maintains contact with the door face or allows air movement through the gap it should be closing.
Standard compression weatherstripping provides adequate contact pressure in calm or low-wind conditions. Under sustained Ottawa Valley westerly wind loads, a standard seal on a west-facing Stittsville entry is being forced away from the door face — the wind pressure against the exterior of the closed door is greater than the seal’s spring-back force — and cold air infiltrates through the gap created. Heavier-profile compression seals with greater restoring force, and properly installed kerf-in seals with positive mechanical retention in the frame groove, maintain contact under the wind load that standard adhesive-backed products can’t resist.

The door frames in Stittsville’s village core homes have been modified, patched, and adapted over decades in ways that make weatherstripping replacement require more assessment than a standard residential entry. A frame that has had foam tape applied over original kerf-in channel seal, then compression strip added over the foam tape, then another layer of adhesive foam when the compression strip compressed flat, has a door stop face that is a layered history of inadequate repairs. Stripping back to the frame and installing a correct-profile seal in the correct mounting position is more work than adding another layer — but it produces a result that actually seals the door.
The newer Stittsville builds in the Fernbank corridor have weatherstripping that is approaching its first replacement interval — typically eight to twelve years for a moderately exposed Ottawa suburban entry. First replacement at this stage is worthwhile because the original builder-specified seals are frequently the minimum product that meets the energy code requirements rather than the best product for Ottawa’s actual exposure conditions. Upgrading to a heavier-profile seal at first replacement produces better thermal performance than simply replacing like-for-like.
