Your siding isn’t just for looks it’s your home’s first line of defense against Ottawa’s harsh weather. But over time, even the best siding can start to break down, costing you in energy bills, curb appeal, and even structural damage.
Not sure if it’s time for a replacement? Here are the top signs it might be time to upgrade your siding.
Your Energy Bills Are Going Up
If you’ve noticed your heating and cooling bills creeping up especially in the winter your siding might not be insulating your home properly anymore. Worn-out siding can let cold air seep in and warm air leak out, forcing your HVAC to work harder.
Tip: Check for drafts around walls or windows this could be a sign of poor siding insulation.
Warping, Cracking, or Bubbling
Take a walk around your home. If you see:
Warped or loose boards
Cracks or holes
Bubbling or blistered siding panels
…those are red flags. These signs often point to trapped moisture, which can lead to rot and mold behind the siding.
Don’t ignore it, water damage can get expensive fast.
3. Fading or Peeling Paint
Good siding should hold its color for 8–10 years. If your siding is faded, chalky, or peeling, it may be past its prime. Faded siding can also be more brittle and less effective at protecting your home from the elements.
Pro tip: If you’re repainting your siding every few years, it's time for a replacement instead.
4. Signs of Mold, Mildew, or Pests
Check for dark streaks or greenish patches — these could be signs of mold or mildew growing under or on your siding. Also, keep an eye out for pest damage, especially with wood or older materials.
Left untreated, this can lead to serious issues inside your walls.
5. Your Home Just Doesn’t Look Great Anymore
Maybe the siding is outdated, the color doesn’t pop, or it’s just not aligned with your home’s value. New siding can instantly boost curb appeal and raise resale value, too.
If you're planning to sell or renovate, this is one of the most valuable upgrades you can make.
Bonus: It’s Over 20 Years Old
Even if your siding looks okay, most materials have a shelf life. Vinyl and wood siding typically last 20–30 years, while fiber cement can last longer. If your home is over 20 years old and the siding’s never been updated, now might be the perfect time.
