# WowFix vs Glass Guru > The Glass Guru's signature foggy-window fix is moisture removal — drying the fog out of the old unit "for half the cost of new glass." WowFix replaces the failed unit outright **from $198, fabricated in our own shop**. The difference is what you're left with: dried-out old glass, or a brand-new sealed unit with its insulation restored. **Free estimate · 4.9 · 473+ reviews** ## Drying the Old Unit vs Replacing It The Glass Guru describes an exclusive restoration method that "removes all that trapped moisture and prevents it from returning" at "half the cost of new glass" (their site, August 2026). Here's the physics we'd want to know as homeowners: fog means the factory seal already failed, and the insulating gas that made the unit efficient escaped long ago. Drying clears the view — it cannot refill the insulation. Even Google's own AI summary of defogging notes it "does not fully restore original insulation value." - Defog: clears the moisture — the failed seal and lost insulation remain - New IGU: fresh seal, fresh air gap, full insulating performance - WowFix new sealed unit: from $198, built in our own shop - Half-price on a dried old unit vs full fix from $198 — run the math for your window ## When Defog Makes Sense — and When It Doesn't Honesty cuts both ways. If a unit is enormous, oddly shaped or historically protected, drying it can be a reasonable stopgap, and The Glass Guru is an established franchise that does it professionally. But for the standard double-pane windows in most Charlotte homes, the arithmetic is stubborn: a new shop-built unit starts at $198, restores the insulation a defog can't, and carries our 5-year parts-and-labor warranty. That's why we quote the real fix first. - Standard double-pane: new unit from $198 usually beats half-price drying - New unit restores insulation; defog restores visibility only - 5-year written warranty on every new sealed unit - [Full IGU guide](/insulated-glass-unit-replacement/) — thicknesses, measuring, prices ## How WowFix vs Glass Guru Works Fog diagnosed honestly, priced exactly, fixed in one visit. - **Confirm It's Seal Failure** — Fog between panes = failed factory seal.

The honest caveat is what defogging can't do: the seal already failed and the insulating gas already escaped, so drying restores the view, not the performance. Google's own AI summary notes defogging "does not fully restore original insulation value." We simply think most homeowners, seeing both numbers, choose the new unit. **Q: Glass Guru says half the cost of new glass — isn't that cheaper?** A: Half of an unpublished number is hard to compare, so run it against ours: a new shop-built sealed unit starts at $198 installed, insulation restored, 5-year written warranty. If a drying quote beats that meaningfully on your window, it's usually a very large or specialty unit — and then it's a fair option. **Q: Does WowFix offer defogging?** A: No. We fabricate new insulated glass units in our own shop from $198, so the honest fix costs close to what drying costs elsewhere — at that gap, selling a service that leaves the failed seal in place isn't something we'd offer family. **Q: Is there a Glass Guru in Charlotte?** A: The franchise lists an East Charlotte location.
