Air movement seems near the sash edge
Operation, latch and weatherstripping are reasonable inspection points, but the exact defect remains unknown.
Notice next: Note whether the sash closes squarely and locks without forcing it.

Air movement near a window
What should you check when a window feels drafty?
A draft can involve an open or poorly latched sash, worn weatherstripping, a gap at the frame, an air path around the rough opening, or air movement elsewhere in the wall. Cold glass can also feel uncomfortable without proving that air is leaking. Do not use the sensation alone to prescribe replacement.
Record the exact location, wind and temperature conditions, whether the unit closes and locks normally, and whether moisture or frame damage is present. A qualified assessment can distinguish adjustment or repair, air-sealing work and replacement. A draft question remains a repair assessment unless the homeowner separately chooses to evaluate replacement.
Put safety before diagnosisDo not remove trim, inject material into unknown cavities or reach outside an upper-story window to find an air path.

U.S. national guidance
What changes after you choose a location?
Choose a state to make the geographic boundary explicit.
A ZIP helps identify possible window installation service areas and building jurisdictions, but it does not prove jurisdiction, address-level coverage or an available window or building-envelope professional.
Applies nationallyThe safety and observation sequence on this page is general U.S. guidance.
Must be confirmed locallyBuilding codes, permits, product approvals, lead-safe programs, contractor requirements, climate design, prices and provider availability require current evidence for the exact property.
Separate glass, sash, frame and opening conditions
Which situation best matches the windows?
Air movement seems near interior trim
The frame-to-opening path or adjacent wall may be involved.
Notice next: Mark the location without removing trim or probing the cavity.
Area feels cold without clear air movement
Surface temperature and comfort can differ from an actual leakage path.
Notice next: Record weather, room conditions and the exact surface that feels cold.
Safe observation
What should you record before the call?
A short, factual description helps the next professional choose the right first inspection without treating a symptom as proof.
A draft sensation cannot distinguish product leakage, installation leakage, wall leakage or surface-temperature effects, and it does not prove replacement is needed.
What to record
- Exact draft location and affected windows.
- Wind, outdoor temperature and indoor condition when noticed.
- Opening, closing, latching and locking behavior.
- Visible gaps, failed finishes, staining, condensation or frame damage.
Stop and get appropriate help
- The sash, glass or hardware is loose, damaged or cannot secure the opening.
- Opening the window creates a child, occupant or fall hazard.
- Draft investigation would disturb painted pre-1978 material or reveal active water damage without the appropriate controls.
Short answers
Questions people ask before the call
Does a draft mean I need new windows?
No. Operation, weatherstripping, frame, rough-opening and adjacent-wall conditions should be separated first.
Can I seal every visible gap?
Not blindly. Drainage paths, materials and the actual air or water boundary must be understood before applying sealant or foam.
Are ENERGY STAR windows automatically draft-free?
No. Certification describes an exact product's ratings; field installation, operation and wall integration remain separate.
