Vinyl Siding Repair & Replacement Services in London, Ontario
Your home’s siding is more than just decoration—it’s your first line of defence against rain, wind, and fluctuating temperatures. But if you’ve noticed cracks, warping, or fading on your vinyl siding, you might be wondering: Should I repair it or replace it entirely?
It’s a question many London homeowners face, especially with Ontario’s unpredictable weather putting exterior materials to the test. The good news? You don’t need to guess. With the right inspection and expert advice, you can make the best long-term decision for your home and budget.
At AM Group Exteriors, we’ve helped homeowners across London repair and replace siding for more than 65 years. Here’s our no-nonsense guide to figuring out when a repair will do—and when it’s time to start fresh.
Why Vinyl Siding Is So Popular
Vinyl siding has become the go-to choice for London homeowners because it’s durable, low-maintenance, and available in endless colours and textures. It resists rot, insect damage, and warping far better than traditional wood—and when installed properly, it can last 30–40 years.
But even the toughest materials can break down over time. Between London’s cold winters, humid summers, and frequent windstorms, siding panels can crack, fade, or loosen, especially if they weren’t installed correctly in the first place.
That’s when it’s time to decide whether repair or replacement is the smarter move.
Signs Your Siding Needs Attention
You don’t have to be an expert to spot early warning signs. Here are a few things to watch for during your next walk around the house:
- Cracks, holes, or chips in panels
- Warped or bulging sections
- Gaps between siding and trim
- Mould or mildew along the seams
- Paint bubbling on interior walls
- Fading or dull patches
If you notice any of these issues, don’t wait. The sooner you act, the easier (and cheaper) it will be to fix.
Fix or Replace? Knowing the Difference
Not every siding problem calls for a full replacement. Sometimes, a small repair is all you need. Other times, patching one area just postpones the inevitable. Here’s how to tell the difference.
1. Small Cracks or Chips — Repair It
Minor damage caused by a stray baseball or hail can often be repaired quickly. Our team can replace individual panels or patch small sections without disturbing the rest of your exterior.
Pro tip: Address these small issues fast. Cracks can allow moisture behind the siding, leading to hidden rot or insulation damage if ignored.
2. Warping and Buckling — Inspect Before Deciding
If panels look uneven or bowed, improper installation or heat exposure may be to blame. Sometimes we can resecure or realign the siding to restore its fit and function.
However, if warping is widespread—or if the underlying sheathing is damaged—it’s usually more cost-effective to replace the entire section.
3. Fading or Discolouration — Replace It
All siding fades eventually, especially on south-facing walls that get the most sunlight. While a deep clean can help, badly faded siding often indicates age and UV wear. In that case, replacement is the smarter long-term investment.
Bonus: New vinyl siding offers UV-resistant finishes and improved insulation value, giving your home a fresh look and lower energy bills.
4. Water Damage or Mould — Replace It Immediately
If you spot mould, mildew, or bubbling paint inside your home, it’s likely that water has penetrated behind your siding. In this case, simple patching won’t solve the problem—you’ll need to remove and replace the affected area to protect your home’s structure.
At AM Group Exteriors, we don’t just swap out panels. We inspect your home’s moisture barrier, insulation, and framing to ensure the issue doesn’t return.
The Hidden Costs of Ignoring Siding Issues
It’s tempting to delay siding repairs, but waiting often leads to bigger (and more expensive) problems. Left unchecked, small cracks can let moisture seep in, causing:
- Rotting wood beneath the siding
- Mould growth behind walls
- Increased heating and cooling costs
- Pest infestations
- Compromised insulation
A quick inspection and timely repair can prevent thousands of dollars in future damage.
