The Two Jobs, Side by Side
Both jobs end with a new window in the same hole. What changes is how much of the old assembly leaves with the sash, and that one difference drives price, glass area, mess, and whether the wall under the window stays dry for another twenty years.
What Comes Out in a Pocket Install
Sashes, stops, parting bead, and either the balances or the old sash weights. The jamb stays. The sill stays. The exterior brickmould stays. A self-contained unit with its own frame, sash, glass and hardware goes into the cavity, gets shimmed plumb and square, screwed through the jamb, sealed at the perimeter with low-expansion foam, and finished inside with a thin cover trim. Interior casing usually never comes off and no siding is cut.
What Comes Out in a Full-Frame Tear-Out
Everything back to the rough framing: jambs, sill, stool, apron, interior casing, exterior brickmould or trim. On a sided wall the crew cuts siding and water barrier back to expose sheathing around the opening. The replacement is a flanged unit or a block frame, set on a sill pan, taped into the water barrier, insulated in the shim gap, and re-trimmed on both sides. Two to three times the labor, and a second trade if the interior is plaster.
The Old Frame Decides First
A pocket insert borrows the squareness, the strength and the drainage of the frame it lands in. Where that frame is sound, you are buying a shortcut with almost no penalty. Where it is not, you are sealing a wet problem behind a window that will outlive the wood holding it up.
The Screwdriver Test
Raise the sash and press a small flat screwdriver into the sill at each outside corner, where sill meets jamb. Sound wood stops the tip cold. If it sinks a quarter inch under thumb pressure, the fibers are gone. Repeat under the interior stool at both ends and at the bottom of the exterior brickmould. Sills in central Indiana fail at the corners first, because that is where wind-driven rain stands and where a winter of freeze and thaw pries the joint open a little further every year.
Checking the Frame for Square
Measure inside the jambs corner to corner, both diagonals. On a three-foot window a difference under a quarter inch is ordinary and an insert will hide it. Half an inch or more and you get a square window sitting in a frame that is not, which reads from inside as a tapered gap running down one side. Measure the width at head, middle and sill as well. A middle number three-eighths of an inch narrower than the head usually means a settled header is bowing the jambs inward, and that is a framing conversation before it is a window conversation.
What Full-Frame Buys That You Cannot See
Most of the value in a tear-out is buried before the trim goes back on. That is exactly what makes it a hard sell, because the homeowner pays several thousand dollars for something that looks identical from the driveway.
The Shim Gap and the Weight Pockets
In a house built before about 1950 the space between window jamb and rough framing is usually empty, and in a weight-and-pulley window it is a pair of open cavities the size of a cereal box running the full height of the opening. In plenty of older Tanglewood houses those pockets connect straight into the wall and, at the top, to the attic. A pocket install cannot reach them. A tear-out exposes them and they get sealed and filled, which is often a bigger comfort gain than whatever glass package is on the order.
A Sill That Actually Drains
A tear-out lets the installer set a sloped sill pan with end dams under the new unit and lap it onto the water barrier below. Whatever gets past the exterior seal in year twelve then runs back out instead of into the framing. There is no way to add that under an insert later.
Getting It Written Into the Bid
The word replacement means nothing on its own. Ask for these lines in writing before you sign anything.
- The scope in physical terms: remove sash, stops and parting bead only, or remove to the rough opening.
- Whether a sill pan and flashing tape are included, and how the pan ties into the existing water barrier.
- A unit price for hidden rot repair, quoted per opening, so a discovery does not become an open-ended change order.
- Who supplies and paints interior trim, and whether drywall or plaster patching is in the price.
- The daylight opening dimensions of the ordered units, not just the frame size, so you can check egress rooms yourself.
- Debris removal and old sash disposal, which is a real cost on a nineteen-opening house.
One more thing worth doing before anyone orders glass. Walk the house and mark every window you would regret shrinking. On most Tanglewood homes that list is short, three or four openings, and it turns an all-or-nothing decision into a sensible mix.
What a Pocket Insert Costs You in Glass
The new frame nests inside the old one, so the daylight opening shrinks. Figure on losing roughly two to three inches of width and two and a half to four inches of height per opening, depending on how heavy the replacement frame is and whether the old jamb liners come out with the sash.
On a 36 by 60 living room double-hung that is a change almost nobody notices. On a 24 by 36 bath window it is close to a tenth of the width, and the casing suddenly looks heavy around a small pane. Two situations make it more than a looks problem: a bedroom or basement window already sitting near the minimum egress opening, and any elevation where some openings get inserts and others get full-frame units. Mixed sightlines on one wall are visible from the street even when the person looking cannot say what is wrong.
Where Each Approach Wins in a Tanglewood Home
Pocket is the right call when the frame passes the screwdriver test, the diagonals are within a quarter inch, the interior trim is original and worth keeping, the openings are generously sized, and the budget has to cover the whole house in one season.
Full-frame earns its money when any of the following is true:
- The sill is soft anywhere, or the stool shows old water staining that nobody has explained.
- The existing window is steel or aluminum set in masonry, so there is no wood jamb to insert into.
- The opening is already at or near minimum egress and cannot afford to lose height.
- Siding is coming off this year anyway, which makes the flashing work nearly free labor.
- The house still has weight pockets and the top-floor rooms are the ones you cannot keep warm.
- The window was replaced once already with an insert, so a second insert would nest inside two frames.
What the Two Jobs Cost in Tanglewood in 2026
| Scope | Typical installed range per opening |
|---|---|
| Pocket insert, mid-grade vinyl double-hung | $575 to $975 |
| Pocket insert, fiberglass or composite | $900 to $1,500 |
| Full-frame, mid-grade vinyl, sided wall | $850 to $1,400 |
| Full-frame, fiberglass or clad wood | $1,300 to $2,300 |
| Sill or framing repair found during tear-out | $150 to $600 extra |
Most Tanglewood homeowners find full-frame lands roughly $250 to $500 per opening above the pocket price for the same window, before any repair turns up. Across fourteen openings that is a $3,500 to $7,000 spread. These are typical central Indiana ranges for 2026 and they move with unit size, second-story access, and how much interior trim has to be rebuilt afterward.
