Good to know
It is critical to make sure that the sealant you are using is compatible with the surfaces to be sealed. Also check drying time, resistance to dryness, the product’s colour and whether or not it can be painted.
Check your product carefully before using it outside. Make sure it is specially designed to conserve its rate of elasticity in spite of temperature variations. Some products feature guaranteed flexibility at temperatures nearing -40°C. Products that are not made to be used outside will lose volume and crack, which leads to increased risk of infiltration. Also make sure you are choosing quality products, as certain low-grade caulking compounds will fissure.

Reasons for re-caulking
To avoid air and water infiltration inside the building. By stopping water from entering, you are protecting wood and structural components. It is important to re-caulk doors and windows because when sealant is dried, old or cracked, it lets in air and allows heat to escape, which can make heating your home more difficult. Sealant that lets in water can lead to significant damage underneath the exterior coating and in the very structure of a building, as well as consequent fungal growth.

- If the old sealant seems difficult to cut, make sure you are using a perfectly sharp blade and repeat as needed.
