Window Replacement Contractor Software in Missouri
A window job is never one window. It's eighteen openings, four sizes, two grid patterns, a bay that needs a site measure, and a homeowner who keeps asking about U-factor. ExteriorPro lets you build the estimate room by room, lock in the spec sheet the manufacturer needs, track lead times when the product's on backorder, and keep the install crew from showing up with the wrong brickmould. Everything tied to the project so the sales rep and the install lead aren't on different pages.
Missouri window shops run tight margins and long lead times. ExteriorPro keeps the opening list tied to the order tied to the install date, so nothing shows up wrong on install day.
From $199/month per location. No credit card required to start.

Missouri sits in the ENERGY STAR North-Central climate zone, and it is a state where both numbers on the label matter. The U-factor sells in January, when the wind comes across the plains into Kansas City, and the solar heat gain coefficient sells in August, when St. Louis sits at ninety-five degrees with the humidity to match. A window that only solves one of those is half a window here.
The housing stock splits by city. St. Louis and its inner suburbs are brick, and a lot of those houses still carry original wood windows that need a careful measure in openings that were never square. Kansas City's Missouri suburbs and St. Charles County are frame houses from the 1980s onward with builder-grade vinyl that is fogging and sticking, and that is the replacement wave that is only getting started. Springfield and Columbia are growing and add new-build work on top.
Window work runs most of the year in Missouri. Winters are cold enough to sell windows and mild enough to install them, and a good installer can swap an opening in January without letting the room go cold. The slowdown is August, not February.
There is no state license or registration for window installation, since Missouri's 2023 contractor registration covers roofing only. The rules are local. Kansas City, St. Louis city and county, St. Charles County, Springfield, and Columbia each license contractors on their own terms. When a window job is part of a hail claim, the state's storm law applies to the deductible, and the contractor cannot offer to pay or rebate any part of it. Custom windows run four to eight weeks from order to delivery, and the install date on the contract has to allow for it.
