Replacement Windows Installed the Right Way

  • Foggy glass or failed seals
  • Water intrusion or wood rot

How Windows & Doors Tie Into Roofing

Most homeowners don’t realize: roof leaks, ice dams, and poor attic ventilation can contribute to moisture issues that show up around windows and trim. If you’re seeing leaks or staining, it may be a roofing issue—not a window issue. We can help you identify the source.

Frequently Asked Questions

How do I know if water near a window is a window issue or roof issue?

Water can travel. If staining appears after wind-driven rain or ice, the source may be roof flashing, trim, or siding above the opening. We’ll inspect and help pinpoint the cause before recommending replacement.

Yes. If we find damaged trim or rot, we can repair or replace affected exterior components so the installation is solid and sealed correctly.
