RenoAtlas.ca1. Diagnose
A split joint can signal movement, failed flashing or water behind the cladding.
Air sealing / cost
House caulking cost: quantity, cost and method
Measure joints, estimate cartridges, and separate material, removal, preparation and access instead of relying on a vague per-window price.
Know before you start: Cartridge coverage depends on joint width and depth; always replace the calculator assumption with the exact product data sheet.
Choose sealant by joint
| Type | Where it may fit | Verify |
|---|---|---|
| Silicone | Compatible glazing and wet areas | Paintability, adhesion and cure |
| Polyuréthane | Compatible moving exterior joints | Primer, temperature and geometry |
| Thermoplastique | Many residential exterior joints | Substrate, application temperature and movement |
| Acrylique / latex | Interior and low-movement joints | Humidity and persistent water exposure |
Work method
2. Remove and clean
Remove failed material and prepare both bond faces as directed.
3. Control the joint
Backer rod and depth are not arbitrary; avoid three-sided adhesion where prohibited.
4. Preserve drainage
Never block weeps, drainage holes or intended water exits.
5. Cure and inspect
Respect weather and cure limits, then inspect gaps, debonding and stretching.

Entered costs are your local assumptions; RenoAtlas does not present them as a quote.
Why two prices can differ
- Full old-sealant removal versus surface overcoating.
- Second/third-storey access, lift or scaffold.
- Actual joint width/depth, backer rod and primer.
- Flashing, rot or substrate repair before resealing.
- Number of colours, details and protection/cleanup time.
