How to Know If Your Windows Are Causing Cold Spots Around the House - Kubala Windows

As the seasons change in Massachusetts and northern Connecticut, many homeowners notice uncomfortable cold spots in their homes. You might be cranking up the thermostat, but certain areas still feel chilly. Often, the culprit isn't your heating system, but rather inefficient or old windows. Identifying these issues early can save you money on energy bills and improve your home's comfort.

Signs Your Windows Are Causing Cold Spots

It's not always obvious that your windows are the source of cold drafts. Here are some key indicators to look for:

**Visible Drafts:** Hold a lit candle or an incense stick near your window frames. If the flame flickers or the smoke wavers, you have a draft.
**Condensation Between Panes:** Moisture or fog between double-pane glass indicates a broken seal, which compromises the window's insulation.
**High Energy Bills:** A sudden or consistent increase in heating costs, especially during colder months, can be a sign of heat escaping through your windows.
**Rotting or Warped Frames:** Old wooden frames can rot, warp, or crack, creating gaps for cold air to enter.
**Difficulty Opening or Closing:** Windows that stick, don't latch properly, or are painted shut might not be sealing correctly.
