Scope of window weatherproofing
Window weatherproofing should start with identifying drafts, visible gaps, failed seals, or water-entry symptoms. Share the window type and where the problem appears rather than requesting sealant everywhere. Ask the provider to distinguish adjustment, weatherstripping, and repair of defects, and to assess whether a larger window or surrounding-envelope repair is needed.
Describe air leakage and water entry separately
Tell the provider what you observe, where it occurs and when it happens. A draft at an operable joint, water at the surrounding wall and moisture between panes can have different causes. Photographs of the whole opening and the affected detail are useful. A request to seal every visible gap should not replace an assessment of the actual leakage path.
Match treatment to the window detail
Ask whether the work concerns weatherstripping, an identified sealant joint or a more substantial installation defect. ENERGY STAR describes air sealing as a distinct home-improvement measure; it is not a promise that one product fixes every window problem. Manufacturer-designed drainage and operating features need to remain functional. Damaged glazing, decayed frames and failed adjoining weather details may require another repair rather than more surface sealant.
Define the repair and its limitations
Agree on the exact joints or components being treated, preparation, accepted material and checks. Painting, replacement parts and surrounding wall repair may be separate stages. Ask what evidence would require further investigation if the symptom returns. The directory does not guarantee a particular energy saving or certify the whole building as waterproof. Complete window replacement should be considered as a separate scope when the assessed condition calls for it.

Project questions
What symptoms should I record before window-weatherproofing work?
Describe where drafts, gaps or water entry appear and provide photographs of the window type. Ask for an assessment of the cause rather than requesting sealant across every joint.
Can weatherstripping address every leaking-window problem?
Ask the provider to distinguish failed seals or adjustment issues from damage to the window or surrounding construction. A larger repair may need assessment before a weatherproofing scope can be agreed.
