§ 01 Quote Check

Check a quote before you sign

Put a quote next to what homeowners actually paid, then check its terms against the law that applies. We never call a quote fair or a scam: we show where it sits, what to ask, and why.

This ZIP is not in a metro area BLS reports on, so this is the national figure.

Your multiplier: ×2.0Median wage × multiplier: $58/hr

You set this; casaq publishes no “typical markup” because we have no citable source for one. OEWS reports what employers pay these workers per hour. A contractor’s bill also covers the business: insurance, licensing, vehicles, tools, office staff, warranty callbacks, unbilled travel time and profit. The wage is a floor for understanding a quote, never a price.

5 · What the job involves

Doors or windows, add or replace

Doors and windows covers anything from one entry door to every window in the house. The survey does not record how many openings were done, so casaq shows the distribution for context only and does not place a single quote on it.

How it usually goes

Measure each opening; choose product line, glass and frame
Order (lead times can be weeks)
Remove old sashes or full frames; repair rot
Install, shim, insulate and flash each unit
Trim, caulk and clean up; lead-safe practices on pre-1978 homes

What moves the price

Number of openings
Insert vs full-frame replacement
Frame material and glass package
Custom sizes, shapes and doors
Rot repair and trim
