When is the best time for a home insulation project?
Planning and scheduling your insulation project well can make a big difference in cost and comfort. While insulation can be installed year-round, certain seasons make the job easier, faster, and sometimes cheaper.
Spring and Fall: Ideal Seasons for Insulation projects
Most insulation experts recommend to do insulation projects in the spring and fall. The weather is mild, which means:
- Easier scheduling — contractors are less busy than during peak summer or deep winter.
- Better working conditions — moderate temperatures help materials install properly.
- Immediate Energy savings — you’ll be ready for both the summer heat and winter cold.
Summer
If the attic is like a sauna in the summer, it is a good time to add attic or roof insulation. The work can be done quickly, but expect slightly higher labor costs if contractors are in high demand.
Winter Upgrades
Insulation projects are also possible in winter, especially for basements, crawl spaces, and interior walls. They can, however, be challenging due to the cold weather. Some spray foam products require a certain temperature to cure properly, so contractors might need to use heaters or wait for warmer days.
If you want the best value and stress-free experience, plan your insulation project for spring or fall. You’ll enjoy flexible scheduling, fair pricing, and immediate comfort improvements before Calgary’s harsh weather hits full swing.
