Window replacement leads from homes still on their original glass.
The best window leads aren't form fills sold to four companies. They're owners of 40-year-old homes who've lived with drafty windows for years and have the equity to fix them. Spur finds those homes by build year, ownership length, and equity, writes a card about their window era, and alerts you when they scan.

The problem
Bought window leads are shared, late, and full of price shoppers.
By the time someone fills out a form, they've already had an in-home pitch from a national brand and anchored on its price.

AI draft for Ruth N. · 1214 N Dryden Ave
Hi Ruth,
Homes on Dryden Avenue were built in the early 1960s with single-pane windows, and a lot of them still have them, sometimes with storm windows added on top. If your front room is cold in January and the glass fogs up on winter mornings, that's why.
Modern double-pane windows with low-E glass make a dramatic difference in a house this age. Because your home was built before 1978, we'll do the work under the EPA's lead-safe rules. Our crew is certified, and we'll give you the required pamphlet before we start.
Scan the code to book a free assessment. We'll show you which windows are worth replacing first and give you a written price.

How to find window replacement leads before anyone else
Most window replacement leads are bought at the bottom of the funnel. The homeowner has already decided to replace, filled out a form, and is collecting quotes. Those leads are expensive, often shared, and price-driven. The alternative is to find owners who need windows before they start shopping, and become their first conversation instead of their fourth.
Property records make that possible. Build year is the best proxy for window type. Homes built before about 1980 commonly have single-pane glass, aluminum frames, or wood windows with storm panels. Homes built from 1980 through the late 1990s usually have first-generation double-pane units whose seals commonly fail after 25 to 30 years. Add owner occupancy and 10 or more years of ownership, and you have homes that probably still have those windows.
Equity is the third filter. A whole-house window project is often $8,000 to $20,000 or more, and owners with substantial equity are more comfortable taking it on, whether they pay cash or finance. Combining build year, ownership, and equity gives you a list of owners with both the reason and the means.
Write to the era. Single-pane homes hear about drafts, frost on the inside of the glass, and cold rooms. 1990s homes hear about fogged glass and failing seals. A card that names the owner's actual problem stands out from discount mailers that say the same thing to everyone.
Plan for compliance. Many of the best window leads are in homes built before 1978, where the EPA's RRP rule requires a certified firm, lead-safe practices, and the Renovate Right pamphlet. Mentioning your certification on cards to older neighborhoods is both required knowledge and a trust signal.
Be patient with the pipeline. Window buyers often scan months before they buy. Keep owners who scanned on a light follow-up schedule, and re-mail the list each spring and fall. Exclusive leads you generated yourself don't expire just because the owner wasn't ready this month.

FAQ
Window replacement lead questions
How do I get window replacement leads that aren't shared?
Build your own list from property records: owner-occupied homes built before 2000, owned 10+ years, with strong equity. Mail them under your name and every response is yours alone.
How do I know which homes still have original windows?
Build year and ownership length are the best proxies. Long-time owners of pre-2000 homes are the most likely to still have the windows the builder installed.
How long do windows last?
It varies by material and climate, but first-generation double-pane seals commonly fail after 25 to 30 years, and single-pane and aluminum windows are well past their efficient life.
Does a window replacement need lead-safe work?
In homes built before 1978, the EPA RRP rule generally requires a certified firm and lead-safe practices when the work disturbs painted surfaces, which window replacement usually does.
What does a window replacement cost?
It varies widely by window type, size, and material, but many whole-house projects fall between about $8,000 and $20,000 or more.
