← Contractor Quote AuditorWhat to check on the estimate
- Window count, sizes and rooms listed individually
- Frame material and product line named
- Glass package: panes, coating, gas fill
- Full-frame replacement versus insert/retrofit
- Interior and exterior trim, casing and caulking
- Disposal of old windows and warranty registration
Questions worth asking
- Is this a full-frame replacement or an insert into the existing frame?
- Which product line and frame material are being installed?
- What is the glass package, and is it the same on every window?
- Who finishes interior trim and exterior caulking?
- Is disposal of the old windows included?
- Who registers the manufacturer warranty, and when?

Why are two window quotes so far apart?
Insert versus full-frame is often the biggest factor, followed by product line and glass package. Those three lines usually explain the gap.
Is trim work usually included?
Sometimes. It is one of the most common exclusions, so it is worth asking about explicitly before signing.
