**Drafts or Cold Spots:** Feeling a breeze even when your windows are closed? This is a clear sign that air is leaking in or out.
**High Energy Bills:** A sudden or consistent increase in heating or cooling costs often points to poor insulation, with windows being a common culprit.
**Condensation Between Panes:** Moisture trapped between glass layers indicates a failed seal, compromising the window's insulating properties.
**Difficulty Operating Windows:** Windows that stick, don't latch properly, or are hard to open and close can have structural issues leading to air leaks.
**Faded Furniture or Flooring:** UV rays entering through old windows can cause damage to your interior furnishings, indicating a lack of proper UV protection.

Questions to Ask Your Window Contractor

Once you've identified that your windows might be contributing to energy loss, the next step is to consult with a professional. Choosing the right window contractor is essential for a successful project. To help you make an informed decision, here are some critical questions to ask before hiring:

What specific energy-efficient features do your windows offer (e.g., Low-E coatings, argon gas, multiple panes)?
Can you provide references from previous customers in Massachusetts or Connecticut?
What is your warranty policy, both for the windows themselves and the installation?
How long have you been in business, and what certifications or affiliations do you hold?
What is the estimated timeline for the project, from measurement to completion?
