Why Your Home Might Be Losing Heat (and How Aftermath Contracting Fixes It)


Home Heat Loss and Heat Gain - How Can Insulation Help


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.
