Attic Insulation Services in London, Ontario
You’ve cranked up the thermostat, but your home still feels chilly. Your energy bills are climbing, icicles are forming along the roofline, and you’ve even heard the faint scurry of something above the ceiling. If any of this sounds familiar, your attic insulation might be to blame.
In London, Ontario, where winters can be brutally cold and summers humid, proper insulation isn’t just about comfort—it’s about protecting your entire home. Insufficient or damaged attic insulation can lead to drafts, ice dams, mould, and even pest infestations.
At AM Group Exteriors, we’ve been helping Ontario homeowners keep their homes warm, efficient, and pest-free since 1956. Here’s how to recognize when your attic needs attention—and why calling in an insulation specialist is the smartest move you can make.
Why Attic Insulation Matters
Your attic is more than just storage space—it’s the thermal barrier between your living area and the outdoors. Quality insulation helps maintain consistent temperatures, prevents moisture buildup, and reduces heating and cooling costs year-round.
In London’s climate, that protection is essential. Poor insulation means warm indoor air escapes during winter, melting snow on your roof and causing ice dams. In summer, it allows hot air to seep inside, forcing your air conditioner to work overtime. Either way, you pay for it in higher energy bills and avoidable repairs.
Signs Your Insulation Needs Attention
If your attic insulation is old, compacted, or damaged, your home will start showing clear warning signs. Here’s what to watch for:
1. Drafty Rooms and Uneven Temperatures
Do certain rooms in your home feel colder than others, even when the heat’s on? That’s a tell-tale sign that your attic isn’t retaining heat properly.
Our fix: We inspect your attic’s insulation levels and seal gaps around vents, wiring, and chimneys. Then, we top it up or replace it with high-performance blown-in insulation, ensuring even warmth throughout your home.
2. Ice Dams Along the Roofline
Those big, glittering icicles hanging from your gutters might look pretty—but they signal a serious problem. Ice dams form when escaping heat melts snow on your roof, which then refreezes at the edges. This trapped ice can lift shingles, cause leaks, and damage your soffit and fascia.
Our fix: Proper insulation combined with adequate ventilation keeps your roof temperature consistent, preventing ice dams before they start.
3. Pests or Unwanted Guests in the Attic
If you’ve been hearing scratching or rustling above your ceiling, pests like mice, squirrels, or birds may have found their way in. Once inside, they tear up insulation to build nests and leave droppings that can contaminate the air.
Our fix: We remove damaged insulation, seal entry points, and install fresh, pest-resistant materials. The result: a clean, well-sealed attic that keeps critters out for good.
4. Skyrocketing Energy Bills
If your utility costs have spiked but your usage hasn’t, your insulation may be thinning or compacted. Gaps in coverage allow heat to escape quickly, forcing your furnace to work harder.
Our fix: Our team measures your current R-value and upgrades it to meet or exceed Ontario’s recommended standards. Most homeowners see energy savings immediately after installation.
What Causes Insulation to Fail
Even the best insulation doesn’t last forever. In London’s damp, fluctuating climate, insulation can lose effectiveness due to:
- Age: Most materials degrade after 15–20 years.
- Moisture damage: Roof leaks or condensation can compress insulation and promote mould.
- Rodent or insect activity: Pests disturb and contaminate materials.
- Improper installation: Gaps and uneven layers reduce efficiency.
- Settling and compression: Over time, insulation settles, reducing its thermal performance.
Once that happens, your home becomes drafty, noisy, and far less efficient.
