Window Replacement in Collin & Rockwall County

For homeowners with fogged glass, drafts, water stains, difficult operation, damaged screens, or storm impact around windows.

What is window inspection and replacement?

Window replacement should solve a documented problem: failed insulated glass, water intrusion, damaged frames, poor operation, or storm impact. John's Roofing checks glass, screens, seals, flashing, trim, and surrounding wall conditions, then explains whether glass, a component repair, or a complete window replacement is appropriate.

How it works

  1. Step 01

    Inspect the full opening

    Glass, sash, frame, screen, trim, sill, flashing, and nearby wall conditions are documented.

  2. Step 02

    Separate symptom from source

    We distinguish glass-seal failure, air leakage, drainage problems, and exterior water entry.

  3. Step 03

    Compare repair and replacement

    The written recommendation explains what can be retained and what must be replaced.

  4. Step 04

    Install, seal, and verify

    The opening is protected, flashed, sealed, operated, and inspected before closeout.

In writing

Warranty and what happens if your claim is denied

  • Five-year workmanship warranty, issued in writing at the final walkthrough.
  • Manufacturer material warranty registered in the homeowner's name.
  • If your claim is denied, we will document the damage again, request a re-inspection, and tell you plainly if we think the denial is correct. You are never charged for an inspection or for claim documentation.

Questions people actually ask

Does fog between window panes mean the whole window must be replaced?

Not always. Fogging usually means the insulated glass seal failed. Some units allow glass-only replacement; frame condition, parts availability, age, and installation details determine the practical option.

Can a roof leak look like a window leak?

Yes. Water can travel from roof-to-wall flashing or a wall penetration before appearing around a window. The source should be traced before replacing the window or applying more sealant.

Are hail-damaged screens and windows covered with the roof?

They may be part of the same storm claim when damage is documented and covered by the policy. Record screens, glazing, frames, trim, gutters, and roof components before repairs begin.
