Window Replacement Proposal: Unit Schedule & Worked Example
Build a window replacement proposal with a unit schedule, product specifications, installation boundaries, energy labels and editable pricing.
Use a schedule for every opening
A window proposal should identify each opening rather than offer an unexplained quantity of “new windows.” Assign IDs such as W1 through W4, with room, measured opening, style, manufacturer/model, frame/color, glazing and accessories. Confirm who approves the final order and how measurements are verified before manufacture.
The fictional example replaces four units in existing suitable openings. Its scope assumes the agreed insert installation, not structural enlargement or full-frame work. Those methods affect trim, flashing, labor and what hidden conditions may become visible.
Compare documented products
Use the actual product's energy-performance information when presenting options. ENERGY STAR explains the NFRC ratings on certified window labels. Record relevant ratings from the selected model; do not promise a specific bill saving or tax credit without a current, project-specific basis.
State what happens to interior and exterior trim, and distinguish the manufacturer's product warranty from the installer's actual workmanship commitment. Energy performance, ordering details and installation quality should not be collapsed into a vague “premium window” label.
Show the unit and installation math
Four illustrative units at $425 cost $1,700. Four installation allowances at $180 add $720; trim at $45 per opening adds $180; an $80 handling/disposal allowance gives $2,680 before tax. These inputs are fictional, and actual prices depend on verified products, measurements and the installation plan.
If one unit is upgraded from $425 to $510, the product change adds $85 before tax, assuming installation is unchanged. If it requires a different opening or installation method, revise the affected labor and trim as well. Client approval should identify the changed unit, not just a new total.
Resolve older materials and concealed work
Paid window replacement in covered pre-1978 buildings falls within EPA's RRP program. Check applicability and required arrangements before committing to disturbance of older painted materials. Our ordinary-opening price does not include that additional scope.
Record visible deterioration during inspection and an approval process for concealed rot or structural work. Confirm lead time with the supplier before promising an installation date. At handoff, check the selected units, operation and listed finish work against the schedule.
