Every window has two kinds of seals, and they fail in opposite ways. Drafts, whistling or water sneaking past a closed sash mean the weatherstripping — the rubber and pile around the moving parts — is worn out; that's a from-$115 swap. Fog, haze or condensation trapped between the panes means the factory seal inside the insulated glass unit has failed; no caulk can reach it, so the sealed unit itself is replaced from $198. One symptom check tells you which repair you're actually buying. - Drafts with the window locked — weatherstripping, from $115 per window - Door perimeter seals — from $175 per door - Fog or moisture between the panes — failed glass seal, new sealed unit from $198 - Not sure?

The exact number goes in writing before any work. **Q: Can you reseal a foggy window without replacing the glass?** A: Honestly — no. The failed seal is factory-welded inside the glass unit where no sealant can reach, and defog drilling only hides the symptom for a season. The lasting fix is a new sealed unit in your existing frame, which is why we quote it straight at from $198 instead of selling a temporary service. **Q: What causes window seals to fail?** A: Sun and temperature cycling age the flexible seal until it cracks and the unit inhales humid air — it's wear, not damage, which is why it shows up on 15-25 year old windows all at once. Weatherstripping simply wears from thousands of open-close cycles. Both are normal aging, and both are parts-level repairs. **Q: Is a failed window seal covered by insurance or warranty?** A: Homeowner policies treat seal failure as wear and tear, so it's rarely covered. Some window brands warranty the glass unit itself — if yours qualifies, we'll say so and install the warranty glass. Either way you get itemized paperwork worth submitting. **Q: My windows are drafty but not foggy — which repair is that?** A: That's the weatherstripping — the seal around the moving sash — at from $115 per window, and it pays for itself in comfort. See our [drafty window repair](/drafty-window-repair/) guide for the symptom-by-symptom walkthrough. **Q: Is it worth repairing a window seal instead of replacing the window?** A: Almost always. A seal is one failed part on an otherwise healthy window: $115-$480 against $1,000+ per opening for replacement. The exception is a frame that's genuinely rotted or broken — and when that's true, our written quote says so. ## Serving NC & Surrounding Areas Same seal pricing, wherever our crews run — find your city below.
