Common Residential Window Repair Issues We Put Right

We've diagnosed nearly every window issue a home can present. Here are the problems our clients call us about most often.

πŸ–ΌοΈ

Window Won't Stay Open

A window that slides shut on its own almost always means a failed balance mechanism, whether a broken spring, worn cord, or spiral balance that has lost tension. Left alone, the window becomes unusable in the open position. We identify the balance type and replace the failed component.

πŸ”§

Sash Sticks or Won't Close Flush

A sticking sash usually means the wood has swollen or warped, or the track has built up paint and debris. Forcing it shut repeatedly can worsen the warping over time. We sand, clean, or repair the sash so it moves and seals correctly again.

πŸ•ΈοΈ

Torn or Damaged Window Screen

A torn or punctured screen lets in insects and reduces airflow control at the window. Small tears spread further with repeated handling and weather exposure. We patch minor damage or replace the mesh entirely depending on the extent.

πŸ”©

Screen Frame Bent or Warped

A bent frame corner often still holds the mesh but no longer sits flush in the window opening, leaving gaps around the edges. Continued use without repair can worsen the misalignment. We straighten aluminum frames or replace damaged sections.

🌬️

Draft Coming From Around a Closed Window

A draft with the window fully closed usually points to worn or compressed weatherstripping rather than a mechanical issue. This drives up heating and cooling costs every month it goes unaddressed. We replace the weatherstripping to restore the seal.

πŸ’§

Fogging or Condensation Between Glass Panes

Fogging trapped between panes means the insulated glass unit's seal has failed and cannot be cleaned away since the moisture is sealed inside. This signals lost energy efficiency at that window. We assess whether the glass unit can be replaced or the window needs full replacement.

πŸ”’

Window Hardware Loose or Broken

Loose or broken locks, latches, and cranks make a window difficult to operate securely. Continuing to use damaged hardware can cause it to fail completely. We repair or replace the hardware so the window locks and operates properly.

🧡

Screen Mesh Sagging or Loose in the Frame

Mesh that sags or has come loose from the frame channel usually means the spline has failed or was installed with incorrect tension. A loose screen lets in insects and looks visibly worn. We remove the old spline and reinstall mesh with proper tension.

🌳

Wood Frame Showing Rot or Soft Spots

Soft or rotting wood around a window frame usually signals moisture has been getting in for some time, often invisibly. Continuing to repair hardware on a compromised frame only delays the real fix. We assess whether the section can be repaired or the window needs replacement.

Customer Voices

Feedback From Around the Area

Natalie B.

Balance fix instead of a new window

Our bedroom window kept sliding shut and I assumed we needed a full replacement. Prime Windows Toronto fixed the balance spring in about twenty minutes and it works perfectly now.

Trevor S.

Screens look brand new again

Had three torn screens from our dog getting excited at the window. They rescreened all of them in one visit and the mesh tension is perfect, no sagging at all.

Priya D.

Good repair, sash took longer than expected

The diagnosis was accurate but once they got into the sash there was more rot than initially visible, so it took an extra hour. They explained it clearly before continuing.

Marcus H.

Honest about needing full replacement

I expected a repair quote but the technician from Prime Windows Toronto explained our frame had rotted too far to fix properly. Appreciated the honesty instead of a band-aid fix.

Isabelle R.

No more draft from the living room window

New weatherstripping made an immediate difference. The room feels noticeably warmer already and the draft we'd been dealing with all fall is gone.

Grant W.

Fixed a bent screen frame cleanly

Prime Windows Toronto straightened a bent corner on our patio screen frame instead of pushing a full replacement. Saved us money and it fits perfectly back in the track now.
