Caulking, Importance and Savings (FAQ)
Why is it so important to do the caulking again?
The Quebec Building Code provides that the techniques used for the construction of the building envelope make it impermeable to air and water infiltration.
Caulking is the ultimate finishing step that must maximize this waterproofing effort in every detail. Caulking is the only way to properly seal the contours of doors and windows as well as the junctions of the various sidings.
It must be admitted that you have probably already experienced air and water infiltration if the current state of the caulking of your building is cracked or taken off.
What are the potential savings in energy costs if we do the caulking again?
First, you will surely reduce your energy costs if you properly seal the contours of the openings to eliminate air infiltration.
However, several factors can influence the percentage of savings, such as weaknesses in insulation or the effects caused by thermal bridges.
Some studies estimate additional energy costs at plus or minus $1.00 for each 12-inch-long slot (CMHC 2009).
Second, you will avoid major and priceless financial disasters if you eliminate any potential for water infiltration, not to mention the possible harmful effects of mould on the health of the occupants.
The different renovation subsidy programs
Over the years, financial assistance programs for building renovations have taken different forms and have been aimed at different audiences.
Each year, our ecoenergy subsidy and Logiréno page tries to provide an update on these tax credits with variable rules.
