Why Older Windows Are Drafty
Many homes built decades ago in Shelby Township keep their character, and they also often keep cold air where you do not want it. This piece explains pragmatic fixes you can expect to see on-site, realistic cost ranges, and when replacement is the smarter move.
Drafts at older windows happen for predictable reasons - failing seals, warped sashes, and gaps where glazing or caulk has given up. You might notice cold drafts at the bottom of a sash, or you might My Quality Windows, Roofing, Siding & More of Shelby Twp see cracked putty and paint that no longer seals the glass.
How to Diagnose Drafts
On a first visit, a technician will inspect the sash operation, press tight against seals to test compression, and run a smoke test to see where air moves. An experienced window replacement company can confirm the cause with a quick inspection.
If the draft is coming from the sash fit, new weatherstripping often solves the problem without replacing the entire window. This fix preserves historic character and is worth trying before more invasive work.
Repairing Glazing and Seals
Old leaded or single-pane units with broken glazing compound benefit from careful re-puttying, which also protects the frame edges. Re-puttying requires a steady hand and time for curing, and a craftsman can match the exterior profile so the work looks original.
Storm windows can cut heat loss and reduce drafts, and they are available in fixed and operable styles to match sash function. Storms are a common choice in Michigan, because they deliver measurable energy savings during long winters without removing historic fabric.
Replacement Scenarios
Double-pane units with a breached edge seal should be replaced rather than re-sealed in the field, because long-term durability is a concern. Replacing the sealed unit improves thermal performance and can be done while preserving the original sash if the glazing pocket and frame are sound.
If repair costs approach replacement prices, or if you want improved U-factor and solar gain control, new windows are often the best investment. Weigh the value of preserved historic character against energy savings and maintenance reduction when deciding.
Use ranges when budgeting: small repairs are inexpensive, mid-level IGU or sash work is moderate, and full replacement with premium materials is the largest investment. Ask installers for itemized quotes that separate materials, labor, and any required flashing or trim work so you can compare apples to apples.
Look for a tradesperson who understands historic windows and can describe approaches that preserve original materials when possible. If energy performance is a priority, request U-factor and SHGC numbers for proposed windows and compare them rather than relying on marketing copy.
Treat the easiest, highest-value fixes first - weatherstripping and re-puttying - then move to IGU or sash replacement if necessary.
