Permanent haze between panes
This differs from removable room-side condensation and can indicate an insulated-unit seal failure.
Independent Ownership and Repair Guide
North Star Window Repair in Hamilton
Start with warranty records and an exact symptom. Brand identification supports the diagnosis, but it does not replace measurements or a condition check.
Use the Original Service Route First
A covered product deserves a warranty review before alteration
If your North Star windows may remain under warranty, locate the purchase agreement, installer information, labels and current terms before arranging independent repair. The party responsible for the original installation may need to inspect the opening first.
For appropriate out-of-warranty work, Windows Hamilton separates replaceable glass or screen work from operation and frame conditions. This avoids ordering a pane when sash alignment or the installation perimeter is the real concern.
We are independent and are not North Star, an authorized dealer or its warranty administrator. We do not provide counter sales for loose parts.
Identify the Actual Failure
Similar complaints can need different trades and scopes
Record when the symptom occurs and whether nearby windows behave the same way.
Draft is felt near one edge
A draft may involve sash seals, locking pressure, frame alignment or perimeter installation—not necessarily the glass.
Water marks appear below the frame
Check exterior drainage and wall connections before applying sealant that could trap water.
Appropriate Independent Service
Measure the component and verify the retained assembly
Availability and fit depend on the installed design, condition and access.
Insulated-unit replacement
Specify dimensions, thickness, coatings, spacer, grids and safety glazing for a failed unit in a sound sash.
Review IGU service
Sash and hardware review
Evaluate locks, hinges or balances alongside sash position and frame square before sourcing a component.
Review repairs
Replacement installation
When the frame or perimeter is compromised, define removal, water management, insulation and finishing as one project.

Repair Value Comes From What Stays
Judge the frame and installation before preserving them
The rest of the opening performs well
Focused service can preserve a sound assembly when one measured component has failed.
- Stable frame
- Predictable operation
- No active perimeter damage
Failures overlap across the assembly
Replacement may be more durable when frame distortion, water entry and multiple worn components occur together.
- Several symptoms
- Perimeter needs correction
- Repair would retain weak materials
Appearance Needs Its Own Review
Match performance first, then compare visible details
A new insulated unit must meet the opening requirements, but older coatings, grid profiles and spacer colours may no longer have an exact visual match. Review adjacent units in daylight when consistency matters.
Ask for the independent repair warranty in writing and keep it separate from any original manufacturer coverage.
