Port Orange Glass · Port Orange, Ponce Inlet & South Daytona, FL
The haze is on the inside of the sealed unit, which is why cleaning it has never worked and never will.
Call (386) 387-3973A double-pane window is two sheets of glass held apart by a spacer around the edge, with the gap sealed and usually filled with an inert gas. The sealed cavity is the entire point: it is what stops heat crossing the window, and it only works while it stays sealed.
Florida is unkind to that seal. The glass expands in afternoon sun and contracts after a thunderstorm, day after day for two decades, and the sealant flexes every time. Eventually it stops keeping up. Once the smallest breach opens, humid outdoor air gets into the cavity, and every night as the window cools that moisture condenses on the inside faces of the glass where nobody can reach it.
What you see is the haze, sometimes a visible tide line, sometimes white mineral streaks after a few years of it drying and re-wetting. The window is not dirty and never was — this is the one glass problem that cleaning cannot touch, which is precisely why people put up with it for years before calling anybody.
Almost everyone told they have fogged windows is quoted for new windows. Sometimes that is right. Frequently it is not.
What has failed is the sealed glass unit — the two panes, the spacer and the seal, as one manufactured item. In a great many cases that unit can be taken out of the existing frame and a new one fitted, with the frame, the sash and the hardware staying exactly where they are. No permit, no wind-load calculation, no contractor license required, no hole in the wall of your house, and a price that is not in the same category as a window replacement.
Whether it is possible depends on the window: how the frame holds the unit, whether the sash can be worked on, whether the frame itself is sound, and whether the original size and thickness can be matched. Some designs make it impractical, and an old frame that is failing on its own merits is a genuine reason to replace the whole thing.
But it is a question that deserves to be asked out loud, and the honest test of a company is whether they raise it before you do.
There are cases where swapping the glass is throwing money at a lost cause, and they are worth knowing so you can recognise an honest recommendation.
If the frame is cracked, distorted, or rotting where it meets the structure, the new sealed unit is going into a compromised opening and will not last. If nearly every window in the house has gone at once, the labor of doing them individually starts to close the gap. If the windows are single-pane originals rather than failed double-pane ones, there is no unit to replace. And if you were planning to upgrade to impact glazing anyway, doing it now rather than twice is straightforwardly cheaper.
Note what all four have in common: they are reasons about your specific windows, observed by someone standing in front of them. None of them can be established over the phone.
There are services that drill the unit, dry the cavity and reseal it. It removes the visible fog. What it does not restore is the sealed, gas-filled cavity that made the window insulate in the first place, and opinions on how long the result lasts vary widely. Ask anyone offering it what specifically is warranted and for how long, and compare that against the price of a new unit before deciding.
Both, but be skeptical of anyone putting a precise figure on the energy side. Once the cavity is breached the window insulates worse than it did — that is not in dispute. How much that shows up on a bill depends on the window, the elevation, how many are affected and how you run the house, and a salesperson quoting you an exact annual saving is estimating, not measuring.
Worth checking before you spend anything. Sealed units often carry a manufacturer warranty measured in decades, and it is sometimes transferable to later owners. If you have the builder documents or a label on the spacer bar between the panes, that is where the manufacturer and date are recorded. On a twenty-year-old house it is a long shot — and it is a free long shot.
The glass is made to your measurements, so there is a fabrication wait between the measure and the fitting — usually the bulk of the elapsed time. The fitting itself is normally quick. Ask for the two dates separately, because "we can come out Thursday" often means somebody with a tape measure rather than somebody with your glass.
Accurate as far as it goes, written August 2026, and general by design. This page covers sealed unit failure in double-glazed windows and the options for repairing it. It is not a code interpretation and it is not a decision about your address — Port Orange runs from the Halifax out to the interstate, and the answer is not the same at both ends.
Two things worth confirming rather than assuming: what the building department with jurisdiction over your address actually requires, and whether the company quoting you holds the license for the part of the job that needs one. Links for both are on this page and neither check costs anything.
