Window Replacement Contractor Software in Illinois

Illinois sits across two ENERGY STAR climate zones. Chicagoland and the northern counties are in the Northern zone, and the rest of the state down to Cairo is North-Central. The U-factor a window needs to qualify is stricter in the north, so a shop that sells in both Rockford and Springfield is quoting two different specs, and the rebate paperwork has to match the right one.

The housing stock sets the job. Chicago's bungalows and two-flats still carry a lot of original wood double-hungs with rope weights, and replacing them means a careful measure in openings that were never square. The suburbs built from the 1950s through the 1990s are the volume market, with aluminum sliders and early vinyl that have failed seals and fog between the panes. The collar counties add newer houses with builder-grade windows that are reaching the age where they stick.

There is no state license for window installation in Illinois. The state licenses roofers and nobody else in the exterior trades. Chicago requires a general contractor license for work inside the city, the suburbs have their own registrations, and downstate is mostly a business registration and a permit where one is required.

The contract is regulated statewide. Any job over $1,000 falls under the Home Repair and Remodeling Act, which requires a written contract stating the total cost with parts and materials listed with reasonable particularity. The contractor hands the homeowner the state pamphlet called Home Repair: Know Your Consumer Rights and gets a signed acknowledgment before the contract is signed. Custom windows take four to eight weeks to arrive, and the contract needs an install date that allows for it.
