Glass Only vs Full Window on a Claim — Sash or Frame Damaged Too
The estimate says glass unit, one line, and the glass is indeed cracked. It is also the least of it. The sash corner split when the hail hit and the frame sill has a hole in it.
Glass only vs a full window on a claim comes down to what the storm hit. If the sash and frame are sound, a new insulated glass unit in the old sash is the right repair. If the sash is bent or cracked, new glass will not seal in it; if the frame is split or racked, only a whole unit stops water. JMB Builders checks all three, photographs what the adjuster missed and lists the correct repair. Twin Cities.

Adjusters see cracked glass from the lawn and write a glass unit. Often that is right. A hailstone or a piece of debris can break the outer pane of an insulated unit and leave the sash and frame untouched, and a new unit made to the old size and coating, set in the existing sash, puts the window back. It is also the cheapest line, and that is why it gets written when the damage went further. A glass unit set into a sash whose corner is split will leak at the corner. A sash set into a frame that is racked or has a hole in the sill will not seal, and the water that gets past it ends up in the wall.
The three parts are checked in order. Glass: cracked, chipped, holed or fogged. Sash: the frame around the glass. Look at the corners for splits, run a straightedge down the rails for bends, and check the sash lock against its keeper. Frame: the part fixed in the wall. Look at the sill, which faces up and takes the hits, for dents through the vinyl or cladding, cracks and holes, and measure the diagonals for racking. Only when sash and frame pass is glass only the right answer. When the sash fails, it is a new sash with new glass. When the frame fails, or the maker no longer supplies sashes and glass for it, it is a whole unit.
Then it has to be shown, not said. Each window gets a close-up of the glass, a close-up of the sash corner and rails with a straightedge in the shot, a photo of the sill with a coin or tape for scale, and a wide shot that says which window. Our scope lists the window as glass, sash or whole unit with a one-line reason. You send the packet to your adjuster as a supplement request; the decision is theirs and we do not promise how it goes. Whatever is approved, we do that repair, and we will tell you plainly when glass only is the right call too.
What you supply
- The adjuster's estimate showing the glass-only lines and the claim number
- Your storm-day photos and the broken glass or sash if you kept them
- Access to each window inside and out, with the sash unlocked so it can be operated
- Window labels or paperwork if you have them, for the maker and series
- Your paint color if interior casing is replaced on a whole-unit swap — painting is quoted as a separate line, or paint it yourself
What JMB supplies
- A glass, sash and frame check on every window on the estimate and the rest of the storm side
- Photos per window: glass, sash corners and rails with a straightedge, sill with scale, and a wide shot
- A scope line per window reading glass, sash or whole unit, with the reason in one sentence
- A walk of the house with the adjuster at re-inspection when you want us there
- New insulated glass units made to the old size and coating, set in sound sashes
- Replacement sashes ordered by the maker's label code, with options such as the maker you had
- Whole units with sill pan, flashing tape, foam, sealant and interior trim reset where the frame failed
- A final invoice matched to the approved scope, with finished photos
How it is priced: per window
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Glass unit size, thickness, coating and tempered or not, for glass-only lines
- Sash availability from the maker, since a discontinued series turns a sash into a whole unit
- Whole units in siding, brick or stucco, which sets the exterior trim and flashing work
- Interior trim disturbed by a whole-unit replacement
- Second-story access for inspection and install
- Windows added to the scope by supplement after re-inspection
Send the adjuster's estimate and a close-up of each window's sash corner and sill. We reply within one business day on which ones look like more than glass.
How long it takes
The check takes a visit. Glass units and sashes are made to order over weeks; several swap in one visit once they land. A whole unit is about half a day each.

Situations and options
Glass only is right
Cracked or fogged glass, sash corners tight, rails straight, sill sound, lock meets the keeper. A new insulated unit to the old size and coating goes in the existing sash and the glazing bead is reset. Trim and wall untouched.
Sash damaged, frame sound
Split corner, bent rail or a sash that no longer locks, in a frame that is square and whole. A new sash with glass is ordered by the maker's label code and swapped into the frame. The wall is not opened.
Frame damaged
A hole or crack in the sill, dents through the cladding, a racked frame or a torn weatherstrip channel. Whole-unit replacement: old frame out, opening checked, new unit set with sill pan, flashing, foam and sealant, trim reset.
Parts no longer made
The sash is damaged but the maker no longer supplies that series. A glass unit in a damaged sash is not a repair. We document the discontinued part and list the whole unit, and matching the neighbors becomes part of the conversation.
Glass Only vs Full Window on a Claim — Sash or Frame Damaged Too: questions, answered
Insurance approved glass only but my window frame is damaged too, what do I do?
Document the frame damage and ask for a supplement. Photograph the sill and corners with a coin or tape for scale, measure the diagonals to show racking, and put a straightedge on any bent rail. Have a contractor write the window as a sash or whole unit with a one-sentence reason. Send that to your adjuster with the claim number and a request for re-inspection. The decision is theirs; the photos make it an easy one.
How do I tell if only the glass is damaged or the sash too?
Look past the crack. Check the four corners of the sash for splits, which on vinyl often start at the weld. Hold a straightedge along the top and bottom rails; a bent rail shows daylight under it. Open the window and lock it; if the lock misses the keeper or the sash binds, it moved. Any of those means a glass unit alone will not seal and the sash should be on the scope.
Why won't new glass fix a window with a cracked sash?
Because the glass unit seals to the sash, not to the frame or the wall. A split sash corner opens a path for water behind the glazing bead and into the sash, and in winter that water freezes and opens the split further. The new glass may look fine for a season. The sash is what holds the seal, so a damaged sash gets replaced with the glass in it.
Can the adjuster see sash and frame damage from the ground?
Usually not. Sash corners, sill dents and racking show up close, inside, with the window open. An adjuster working from the lawn sees the glass and writes the glass. That is why the photos matter: a close-up with scale and a straightedge shows what the ground view hides, and a request for re-inspection gets someone to the window. We come along when you want us there.
Does a whole-window replacement cost the insurer more than glass only?
Yes, and that is not the question. The question is which repair stops the water. If the frame is split, a whole unit is the repair, and the scope should say so with the evidence. We list the correct repair for each window regardless of which line it is, and we say glass only when glass only is right. Your adjuster decides what the policy pays; we do not promise the outcome.
What if the window maker no longer makes sashes for my window?
Then a damaged sash cannot be replaced on its own and the window becomes a whole-unit line. We document the maker, series and the discontinued part, and list the full replacement with the reason. A new unit beside old ones raises a matching question; Minnesota has a matching rule for replacement-cost policies, and how it applies to your claim is a question for your agent.
