Window and door installation no-shows happen at three points, each with a different cost profile. A measure visit no-show costs you 60 to 90 minutes of professional measurement time. A cancellation after windows are ordered but before installation costs you the manufacturer's fabrication deposit and potentially a non-returnable product. An installation day no-show with a crew on site costs crew wages for a blocked day and a non-recoverable scheduling slot. Each situation requires a different financial protection mechanism.
Measure visit no-shows: the filtering problem
Window replacement companies that offer free measure appointments often find their measure calendar fills with homeowners who are comparison shopping without a real decision timeline. A homeowner who books measure appointments with four window companies, receives four quotes, and then takes 6 months to decide has cost each installer a 90-minute professional visit that produced no revenue. Three of the four installers get ghosted entirely.
A $75 to $100 measure appointment deposit filters for homeowners who are in the decision phase. Homeowners who are genuinely planning to replace their windows within the next 60 to 90 days do not hesitate on a $75 deposit that applies toward the project. Homeowners who are browsing prices without a real timeline often decline and book a competitor who offers free measures. This is a positive outcome: your measure calendar is populated by buyers rather than browsers.
The financial protection is secondary to the filtering effect. At $100 per measure deposit and a 90-minute visit at $75 per hour professional time cost, the deposit covers the direct time investment in a no-show. The more important benefit is fewer wasted visits with homeowners who were never going to buy in the first place.
The custom order cliff: where cancellations become expensive
The most financially dangerous point in the window installation business is the moment you place the order with your fabricator. Replacement windows are manufactured to the exact rough opening dimensions of each specific opening in the homeowner's house. A 36-inch by 48-inch double-hung low-e argon-filled window in white vinyl for a specific opening is not a standard inventory item. It cannot be returned, cannot be resized, and can only be installed in one specific place in the world: the opening it was built for.
A homeowner who cancels the day after you place the fabrication order has created a non-returnable product. Your fabricator's deposit, typically 30 to 50 percent of the window cost, is gone. If you ordered 15 windows for a whole-house replacement, the fabrication commitment alone runs $3,000 to $6,000 before labor or installation costs.
Your project signing deposit must be collected before you place any fabrication order. This is not optional. The sequence is: homeowner signs contract, homeowner pays project deposit, then you place the fabrication order. An installer who places the order before collecting the signing deposit has created an exposure that the deposit cannot cover retroactively.
Installation day crew no-shows
An installation day no-show with a window crew on site is a full-day loss. A two-person window installation crew for a whole-house replacement represents $600 to $900 in crew wages for the day. When the homeowner is not home or the property is inaccessible, that crew cost runs regardless. Your policy must address this explicitly.
The installation day cancellation or no-show policy should specify a crew deployment fee equal to the crew's minimum daily wage commitment. For a 2-person crew at $25 per hour over an 8-hour day, that is $400. For a 3-person crew, $600. This fee applies when the homeowner is not present at the scheduled installation start time, when the property is not prepared per stated requirements, or when access issues prevent the installation from proceeding.
This fee is separate from the project deposit. The project deposit protects the window fabrication cost. The crew deployment fee protects the labor cost of a wasted crew day. Both should be in your contract.
Setting the right project signing deposit
The project signing deposit for a window replacement project should be calibrated to your actual fabrication commitment. If your window manufacturer requires 40 percent of the window cost to place the order, your customer deposit should be at least that amount. For a $6,000 material cost on a 10-window project, your fabricator requires $2,400. Your customer deposit should be at least $2,400 before you place any order.
Industry standard for window replacement is 25 to 40 percent of the total project cost. For a $9,000 window replacement project (materials plus labor), a $2,250 to $3,600 deposit is appropriate and expected by homeowners who have purchased home improvement projects before. Frame it clearly: the deposit covers the window manufacturing order placed on your behalf.
GrabMySlot handles measure appointment deposits efficiently. For project signing deposits on larger window projects, collect those through your contract management process or a direct payment link. The amounts are too large for a booking page deposit and too legally significant to handle outside a signed contract.
GrabMySlot is free to start. You pay 3 percent only when you collect a deposit. Set up your booking page in under five minutes at grabmyslot.com.
