Visible cracks, gaps, or missing caulking may mean your windows are no longer properly sealed against drafts and water. In Winnipeg, exterior joints endure intense sunlight, seasonal movement, and repeated freeze-thaw cycles, making condition more important than age when deciding on repairs.
Once the problem has been traced to the perimeter joint, the work should follow three practical steps:
The sealant must suit the joint, surrounding material, expected movement, and outdoor exposure. You can only select the right product after assessing the window and joint; one caulk isn't suitable for every application.

When failed perimeter caulking causes drafts or lets water around a window, proper joint preparation and a clean, new seal can fix the problem and improve the finished appearance. Bresara provides window caulking in Winnipeg for homes, upper-storey windows and commercial buildings, with access requirements determined by the building type, elevation and site restrictions.

The cost and timing depend on the actual scope of the work. Useful details include:

Inspect exterior caulking annually and replace it based on condition rather than a fixed schedule. Caulk and gaskets may begin to fail after roughly 10 to 15 years, while south-facing windows can deteriorate sooner because of sun exposure. Cracking, shrinkage, or separation matters more than age alone when determining how often you should replace your window’s caulking.
Look for cracking, peeling, shrinkage, gaps, or sections pulling away from the frame. Caulk that crumbles or smears when touched is also failing and needs to be replaced. Fog between panes or soft wood points to a different problem.
Yes, when the draft is coming from failed perimeter seals around the frame. Re-caulking helps block outside air and reduce unnecessary heat loss.
Loose, cracked or detached caulk should be removed so the joint can be cleaned and prepared before new sealant is applied. Adding a fresh bead over failing material can leave the original problem in place. How much needs to be removed depends on the condition of the existing joint.
Yes. Exterior caulking must tolerate moisture, sunlight, temperature swings and joint movement. Interior caulking is chosen for indoor conditions and humidity shifts, and it may need to be paintable so it fits the decorating plan. The two products are not automatically interchangeable.
Mild to warm, dry weather generally provides better conditions for adhesion and curing. Some products allow cold-weather application, but low temperatures can slow or interfere with curing and may lead to failure after the weather warms. Conditions and product suitability need to be checked before work begins.
