How Far in Advance Should Contractors Order Windows?

For contractors, the best time to order windows isn’t simply “as early as possible.” It’s early enough to accommodate the actual product lead time while keeping specifications, dimensions, and project decisions far enough along to place an accurate order.
That distinction matters on new construction and renovation projects. If windows arrive late, the effects can extend beyond the openings themselves. Dry-in, exterior work, insulation, drywall, trim, and other scheduled work may be affected.
The better approach is to plan the window package early and work backward from the date the windows need to be on site.
Why Window Lead Times Matter for Contractors
A quoted lead time is only one part of the construction schedule. Contractors also need time to finalize product selections, review plans, confirm specifications, place the order, coordinate delivery, and prepare for installation.
One specialty unit can also affect an otherwise straightforward package. Large openings, custom shapes, unusual configurations, specific finishes, or other made-to-order features may require more time than standard units.
This is especially important when the project has a firm dry-in or installation date. In Chicagoland, a late-summer or fall delay can push exterior work into colder weather, leaving less flexibility in the schedule.
When to Order Windows Before Installation
There isn’t one lead time that applies to every window Woodland Windows & Doors sells. Timing varies by manufacturer, product line, window type, and configuration. Current manufacturer availability also changes throughout the year.
For that reason, contractors should connect with Woodland during the planning stage rather than relying on a general industry estimate. Woodland can review the proposed window package and provide current lead-time information for the products being considered.
Remember that production time may not begin when you first request pricing. The order needs to be sufficiently finalized before it can move forward.
If you have blueprints, send or bring them to Woodland early. Our team can assist with blueprint takeoffs, product selection, value engineering, and manufacturer resources so you can establish a realistic ordering schedule.
What Can Delay a Window Order?
Several details can add time between product selection and jobsite delivery, including:
- Custom sizes, shapes, colors, or configurations
- Specialty glass, grille, hardware, or finish selections
- Large or complex window and door assemblies
- Changes to plans or opening dimensions
- Architectural or customer approvals
- Manufacturer production schedules and product availability
- Increased seasonal demand
That’s why “standard lead time” can be misleading. Two projects using the same manufacturer may have very different timelines depending on what is actually specified.
How to Keep Your Project Schedule on Track
Start by identifying when the windows need to arrive, then work backward, accounting for current product lead times, final approvals, order processing, and a reasonable schedule buffer.
Most importantly, identify potential long-lead products before they become critical-path problems. Waiting until framing is well underway to start discussing the window package can leave fewer options if a selected product requires additional production time.
