What’s Included in a Window Replacement Quote (and What Should Be)
What’s included in a window replacement quote is the whole question. A real quote is a document, not a figure. It lists every opening, names the exact product and glass, states how each window will be installed, and puts the finish work and disposal on their own lines. If you can hand it to a second installer and they could build the same job from it, it is complete. If you cannot, something is missing, and that missing piece is usually where the install-day surprise lives.
Here are the twelve line items a written quote should include, the six red flags that mean the quote is not finished, and a sample quote read the way a good one reads.

The twelve line items a written quote should have
- 01
Every opening, individually
Location (e.g. "kitchen, rear"), rough size, style, and its own line. A house-wide lump sum hides which windows need extra work and why.
- 02
Manufacturer and product line
The actual series name, not just the brand. Most manufacturers sell three or four tiers under one logo with very different frames and warranties.
- 03
Frame material and color
Vinyl, fiberglass, composite, or wood-clad; interior and exterior color; any woodgrain or painted finish listed as its own option.
- 04
Glass package, with ratings
Number of panes, low-E coating type, gas fill, spacer type, and the U-factor and SHGC from the NFRC label. "Energy-efficient glass" is not a spec.
- 05
Installation method, per opening
Insert (pocket) or full-frame, stated for each window. Full-frame openings should list new sill, flashing, and insulation.
- 06
Hardware, screens, and grids
Lock style and finish, full or half screens, grille pattern and whether grids are between the glass or applied.
- 07
Exterior finish work
Aluminum capping or new brickmould, caulking, and any siding or stucco repair around the opening.
- 08
Interior finish work
Stops, casing, jamb extensions, drywall touch-up, and who paints. On older Valley homes this line is often the difference between quotes.
- 09
Removal, disposal, and permits
Hauling old units away, lead-safe practices on pre-1978 homes, and who pulls any municipal permit.
- 10
Warranties, both of them
The manufacturer warranty on the window (glass, frame, hardware) and the installer’s labor warranty, each with its term and whether it transfers to a buyer.
- 11
Terms and validity
How long the quote holds (30 days is standard), what is due when, and what happens if scope changes after measuring.
- 12
Schedule
Estimated lead time to manufacture, expected install days, and what happens if a unit arrives damaged.
Six red flags on a window quote
None of these mean the installer is dishonest. All of them mean the quote is not finished, and an unfinished quote is one you cannot compare or hold anyone to.
Verbal-only quote
A figure spoken in the driveway is not a quote. If they cannot write it down, they can change it.
"Today-only" offers
A quote that vanishes when the salesperson leaves is a pressure tactic. Real installers hold a quote for 30 days.
No measurements
A quote produced without measuring every opening is a guess. Expect a tape measure, a level, and a diagonal check on older frames.
A single lump sum
One total for the whole house makes it impossible to compare, cut scope, or catch a missing window.
"Lifetime warranty," no document
Lifetime of what? Ask for the written warranty terms. Many exclude labor, glass seal failure after a period, or transfer to a new owner.
A deposit before a written quote
A deposit should follow a signed, itemized agreement, never precede one.
Sample quote anatomy: a Bethlehem twin, 10 openings
Here is how a complete quote reads for a common Valley house. Notice that each line says where, what, which glass, and how it is installed. Yours will be measured, and the specifics will be yours; the shape of the document should look like this.
| Where | What | Glass | Install |
|---|---|---|---|
| Living room, front | Picture 60×48, fiberglass, white | Low-E, argon, U 0.27 | Insert |
| Living room, flankers | 2 casements 24×48, fiberglass | Low-E, argon, U 0.27 | Insert |
| Bedrooms 1–3 | 5 double-hung 32×54, vinyl | Low-E, argon, U 0.28 | Insert |
| Kitchen, rear | Double-hung 32×46, vinyl | Low-E, argon, U 0.28 | Full-frame (soft sill) |
| Bath | Awning 30×20, vinyl | Obscure, low-E, argon | Insert |
| Exterior | Aluminum capping, 10 openings, white | — | Included |
| Interior | New stops and casing, kitchen only; homeowner paints | — | Included |
| Removal | Disposal, lead-safe practices (pre-1978) | — | Included |
| Warranty | Labor 10 yr · Manufacturer limited lifetime, transfers once | — | Written |

Why the format matters more than the total
Two quotes for the same house can look completely different and both be honest, because they describe different jobs. One includes capping and a full-frame kitchen window; the other assumes inserts everywhere and leaves the old brickmould. The only way to see that is on paper, line by line. That is also why the quote you get through this site is written this way before any deposit changes hands.

What Lehigh Valley quotes tend to leave out
In the Valley’s older boroughs, the line most often missing is interior finish: who replaces the stops and casing after a full-frame install on a 1920s twin, and who paints them. In the townships built since 1990, it is the glass line, where “energy efficient” stands in for a U-factor. In locally designated historic districts, it is the exterior profile and color that any review tends to focus on. Ask for each of those in writing and you have closed the three gaps that cause most of the install-day disagreements homeowners here report.
Quote line-item questions
Should a window quote include the permit?
If your municipality requires one, and some do for full-frame work or a change in opening size, the quote should say who pulls it and that it is handled. Most Lehigh Valley municipalities treat like-for-like insert replacement as routine, and the quote should say that too; the installer confirms with the borough or township office before work starts.
Is it normal for a quote to skip the glass ratings?
It is common, and it is a gap. Ask the installer to add the U-factor and SHGC from the NFRC label for each glass package quoted. Without them you cannot compare one quote’s "energy glass" with another’s.
How long should a written quote be valid?
Thirty days is standard, and most installers will extend it if you ask before it lapses. A quote from last year will usually be refreshed rather than honored as-is because product lines and lead times change.
What if the quote lists a brand I have not heard of?
Many excellent windows are made by regional manufacturers you will not see advertised on television. Look up the NFRC ratings and the written warranty, and ask the installer why they chose that line. A clear answer is a good sign.
Can I ask for the quote to be split into phases?
Yes. Any installer working from an itemized quote can group openings into phase one and phase two. Ask them to show both versions so you can see what changes when the job is done in one visit versus two.
Will the quote from this site have all of this?
That is the standard every installer in the network agrees to: a written, itemized quote per opening, with product, glass, installation method, finish work, disposal, and warranty terms, before any deposit.
