A big spring drop fills the calendar for six weeks. By midsummer the installers are idle and you're buying leads again.
Window play · Direct mail program
A window direct mail program that books assessments every month, not every spring.
Most window companies mail in bursts: a big drop in spring, then silence. A program keeps four standing lists running all year, each with its own card, each measured by cost per signed project. Spur builds the lists from property data, writes and mails the cards, and shows you which list closes.

The problem
Window companies live on spring blasts and expensive lead forms.
Entry and patio doors are fast, profitable installs, but most mail only talks about windows, so owners never think to ask.
One mailer to a whole zip can't tell you whether original windows, sliders, or new buyers produced the signed jobs.

AI draft for Victor A. · 3406 Hedgerow Ln
Hi Victor,
Homes on Hedgerow Lane were built around 1996, and many still have their original sliding patio doors. After nearly 30 years, the rollers wear, the track fills with grit, and the seals that keep the Texas heat out start to fail.
A new patio door with low-E glass slides with one finger, seals tight, and blocks much of the afternoon heat that comes through that big pane of glass. Most installs take a single day.
Scan the code to see styles and book a free measure. You'll get a written price that's good for 30 days, not 30 minutes.

How to build a window and door direct mail program
A direct mail program is a set of standing lists, each with its own message and schedule, that keep running month after month. For a window company, that's the difference between a crowded spring and an idle summer, and a pipeline that stays full year-round. Window buyers take weeks or months to decide, so steady mail produces a steady flow of assessments that turn into installs later.
Most window companies need four lists. Original windows: owner-occupied homes built before about 2000 and owned 10 or more years. Patio sliders: homes built roughly 1985 to 2005, whose original sliding doors often have worn rollers and failing seals. Entry doors: long-time owners of higher-value homes, where a new front door is a fast curb-appeal win. New buyers: recent purchases of older homes, whose owners plan upgrades in the first year.
Give each list its own card. Window cards talk about the home's era, comfort, and fogged glass. Slider cards talk about doors that stick and leak air. Entry door cards are about curb appeal, security, and a door that seals. New-buyer cards offer a free whole-house window and door assessment to help them plan. One flyer can't carry all four messages.
Set a rhythm. Run the core lists monthly so the pipeline never empties, then add pushes before the seasons when owners feel their windows most: early fall, before the first heating bills, and late spring, before air conditioning season. Spur refreshes each list automatically and mails only new matches.
Measure by cost per signed project, not response rate. A slider list might produce more scans than the window list, but the window list may produce bigger contracts. Because every card has its own QR code, you can see scans, assessments, and signed projects by list.
Keep the program honest. Avoid fake deadlines and "today only" pricing, which homeowners associate with the national brands. And don't mention the federal 25C credit, which ended for windows and doors installed after 2025. A written quote that stays good for 30 days is a stronger differentiator.

A year of mail costs less than one small window job.
- Spur Team: $588/yr, plus 2,400 cards on Team at $0.94 each = $2,256
- 3 window projects (~$36,000) + 6 patio doors (~$18,000) + 4 entry doors (~$8,000) ≈ $62,000
- Year one total cost: $2,844

FAQ
Window direct mail questions
How should a window company use direct mail?
Run four standing lists, original windows, patio sliders, entry doors, and new buyers, each with its own card, refreshed and mailed monthly.
How much should a window company spend on direct mail?
Work back from cost per signed project. Window projects often run five figures, so even a modest close rate supports a steady monthly budget. Track by list and fund what closes.
When is the best time to mail window offers?
Monthly for the core lists, with extra pushes in early fall before heating bills arrive and in late spring before air conditioning season.
Can Spur exclude my past customers?
Yes. Upload a customer CSV from your CRM or a spreadsheet, and Spur removes those addresses before mailing. Past customers can get their own card.
Should I market doors separately from windows?
Yes. Patio and entry doors are quick, profitable installs with their own reasons to buy. A separate card for each gets doors noticed.
