Window Repair Services We Offer
Fogged / Failed Glass Seal Repair
When double-pane or triple-pane glass units develop condensation or fogging between the panes, the insulated glass unit (IGU) seal has failed. This is one of the most common window problems in Portland's 15–25-year-old housing stock.
The glass unit itself can often be replaced without replacing the entire window frame, at approximately 30–50% of the cost of a full window replacement.
We identify the window brand and product line, source the matching replacement IGU, remove the failed unit, and install the new one with proper glazing and sealing.
Note: Fogging that appears on the inside of the glass (room-facing surface) is condensation from humidity — a ventilation issue, not a window defect. We distinguish between these on-site so you don't pay for an IGU replacement you don't need.
Draft and Air Leak Repair
Drafts from windows are rarely from a failed window — they're almost always from inadequate air sealing in the gap between the window frame and the rough opening, or from deteriorated weatherstripping.
We remove interior trim, inspect the air sealing, fill gaps properly with low-expansion foam, replace deteriorated weatherstripping, and reinstall trim.
This repair dramatically improves energy performance and comfort at a fraction of the cost of replacement.
We also re-caulk exterior joints where the original caulk has dried, cracked, or separated — a common source of water infiltration that is often mistaken for a window failure.
Hardware Repair & Replacement
Broken cranks (casement windows), failed tilt latches (double-hung), broken sash locks, and non-functional operators are all repairable without replacing the window.
We source replacement hardware across all major brands — Milgard, Andersen, Marvin, Jeld-Wen, Pella, and most others.
Typical repair time: 30–60 minutes per window once parts are sourced.
Broken hardware is one of the most common reasons Portland homeowners call us — and one of the most unnecessary causes of window replacement.
Sticking or Hard-to-Operate Windows
Windows that stick, bind, or require significant force to operate are often suffering from one of three issues: paint build-up in the channel (common in older Portland homes that have been painted multiple times), swollen wood from moisture exposure, or sash hardware that has failed or shifted.
We diagnose the cause on-site before recommending a repair approach. In many cases, a careful cleaning, adjustment, and wax treatment of the channel fully restores operation without any part replacement.
If the sash or frame has swollen due to moisture intrusion, we assess whether the moisture source has been corrected and whether drying the wood out is sufficient, or whether the unit needs replacement.
Caulking, Flashing & Water Leak Repair
Water coming in around a window frame is rarely due to a defective window — it's usually caused by failed exterior caulking, missing or improperly installed head flashing, or a failed sill pan.
We address the actual source of the water intrusion — not just the symptom. This may involve re-caulking, re-flashing, and, in cases where water has been getting in for an extended period, inspecting and repairing any rot or moisture damage in the rough opening framing.
If we find dry rot behind the window during a repair call, we address it then, rather than closing everything up and having it return as a more expensive problem in a few years.
When to Repair — When to Replace: An Honest Assessment
We don't push replacement when repair is the right answer. Here is our honest assessment framework for the most common window conditions:
