Most homeowners start noticing drafts, cold spots, or rising heating bills when winter hits. One of the most searched questions online every year is:
“Why does my home stay cold even when the heat is running nonstop?”
The answer is usually the same:
your home is losing heat faster than your furnace can replace it.
In cities like Vancouver, Burnaby, Coquitlam, North Vancouver, and West Vancouver, this happens more often because the climate is wet, windy, and constantly shifting temperatures. Aftermath Contracting deals with these issues every week — and most problems come from areas homeowners never expect.
1. Heat Escapes Through Weak Exterior Walls

If siding is old, cracked, or pulling away, cold air passes straight through the wall system.
Moisture trapped behind siding can also compress insulation, making it almost useless.
Signs this is happening:
Cold walls when you touch them
Rooms that never warm up evenly
Higher heating bills
Musty smell near exterior walls
Fixing the siding and repairing moisture-damaged insulation instantly boosts indoor comfort.
2. Air Leaks Around Windows & Doors
Windows and doors look sealed — until the first cold wind exposes every gap.

Common leak points:
Old caulking
Loose trims
Failing seals
Gaps behind window frames
These small leaks can account for 25–30% of total heat loss. Aftermath crews reseal, re-insulate, and rebuild any damaged framing around these areas.
3. Poor Attic Insulation (One of the Biggest Causes)
Warm air rises, and if the attic isn’t insulated properly, it escapes instantly.

Why this matters:
Heat rises into the attic
It escapes through the roof
Your furnace runs constantly
Energy bills skyrocket
Wet climates also reduce insulation effectiveness over time — something most homeowners never consider.
4. Hidden Moisture Damage Inside Walls
Water entering through siding, roofs, or windows can soak into sheathing.
Wet materials lose insulation ability and allow heat to escape faster.

This is a common issue in coastal BC homes.
Moisture behind walls leads to:
Heat loss
Mold growth
Soft framing
Outdoor air sneaking in
Aftermath uses moisture detectors and thermal imaging to find the exact problem areas.
5. Your Home Was Never Built for Modern Efficiency
Older homes were constructed under different building standards.
Walls weren’t sealed as tightly, barriers weren’t as advanced, and insulation options were limited.

Upgrading your home’s exterior systems makes a dramatic difference in:
Comfort
Air quality
Energy efficiency
Long-term durability
