Windows & Doors for New Construction: A Builder's Guide

Windows and doors sit on the critical path of almost every new-construction schedule: framing waits on rough openings being finalized, dry-in waits on windows being installed, and interior trades wait on dry-in. Get the sourcing timeline wrong and a six-week window lead time becomes a six-week schedule slip. Here’s how to keep that from happening.

Spec early, not at framing

The single biggest cause of window-related delays is starting the spec process once framing is already underway. Lock in the window and door schedule — sizes, materials, glazing, hardware — before framing starts, so the rough openings are built to match the actual units rather than the units being adjusted to match a guess. Our spec guide walks through the order these decisions usually need to happen.

Understand the real lead time

Custom windows are made to order, not pulled from inventory, so lead time is a real scheduling constraint, not a formality. Build it into the master schedule the same way you’d sequence any other made-to-order component, and order early enough that the units arrive when the openings are ready — not weeks before, sitting exposed on site, and not after framing has already moved past them.

Price the whole job, not the sample unit

A quote for one sample window rarely reflects what a full new-construction order actually costs, because a real job mixes fixed and operable units, multiple sizes, and often several materials across one elevation. Our cost guide breaks down what actually drives the number so you can budget the full schedule of openings accurately, not just the headline unit price.

Coordinate delivery like any other trade

Direct-to-builder delivery — product shipped straight from manufacturing to your site — removes a dealer handoff from the schedule, but it still needs the same coordination as any other delivery: confirmed site access, a plan for who receives and stages the units, and a delivery window that matches when the crew is actually ready to install, not just when the truck is available.

Working with Bellevue on a build

Bellevue ships windows and doors direct to the job site, with every size, finish, and hardware configuration included in one all-in quote rather than a base price plus a list of upgrades — which makes budgeting the full opening schedule more predictable. Our builder portal lets your team track quotes, floor plans, and order status against each project as the schedule evolves. Send us your opening schedule through a quote request and we’ll return a configured, itemized quote within one business day.
