Is it time to replace my windows or doors?

Not sure if it’s time for new windows or doors? Over time, wear and tear can lead to inefficiencies, security concerns, and a less comfortable home. If you’ve noticed any of these signs, it may be time to explore new, energy-efficient options that enhance both your home’s look and performance.

  • Drafts or rising energy bills

    If you feel cold air seeping in during winter or your energy costs keep climbing, outdated windows and doors may be to blame for poor insulation.

  • Difficulty opening/closing

    Warped frames or worn-out hardware can make windows and doors hard to operate, which can be both frustrating and a safety issue.

  • Condensation between window panes

    Foggy or hazy windows indicate a broken seal, which means they’re no longer insulating your home effectively.

  • Warping, rotting, or visible damage

    Moisture exposure can cause wood to swell, crack, or rot, while dents and damage in any material can affect both function and appearance.

  • Outdated appearance

    Old, faded, or mismatched windows and doors can make your home look dated, reducing curb appeal and even impacting resale value.

  • Outside noise intrusion

    If you’re noticing more street noise than before, your windows and doors may not be providing proper sound insulation, which can impact your home’s comfort.
