Why Window Repair Matters for Your Home
Windows play a crucial role in your home's comfort, energy efficiency, and security. Damaged or malfunctioning windows can lead to:
✔ Higher energy bills (up to 30% heat loss/gain)
✔ Security vulnerabilities (easier break-in access)
✔ Moisture damage (wood rot, mold growth)
✔ Reduced home value (poor curb appeal)
Timely window repair helps maintain your home's structural integrity while saving money on energy costs.
