Window replacement leads from homes old enough to need them.

Spur finds homes with single-pane, aluminum, or first-generation double-pane windows by build year and ownership, writes a postcard about comfort and energy use for each owner, and mails it with a QR code to your estimate page. You reach them before the big national brands do.

National window brands own the mailbox. Local installers rarely get a look.

Big brands mail constantly

Homeowners get heavy-discount mailers from national window companies every month. A generic local flyer gets lost in the stack.

Leads come at the end

By the time a homeowner fills out a lead form, they've already booked two in-home estimates with someone else.

Wrong homes on the list

EDDM routes include new builds with modern windows and renters who can't make the decision.

AI draft for Paula G. · 2215 Fernwood Dr

Hi Paula,

Homes on Fernwood Drive were built in the late 1980s, and most still have their original double-pane windows. After 30-plus Illinois winters, the seals between the panes often fail (you'll see fogging), and frames and weatherstripping start letting in drafts.

Not every window needs replacing at once. We offer a free assessment where we check each window and door, show you which ones are losing the most, and give you a written price for replacing only those, or all of them, so you can decide.

Scan the code on this card to book a time. We're local, we install with our own crews, and we don't do high-pressure same-day pricing.

How to find window replacement leads before the national brands

Replacement windows are a big-ticket, considered purchase, and homeowners usually get several estimates. National window brands spend heavily on mail and TV, which means the homeowner's first impression of the category is often a heavy-discount offer with a same-day signing deadline. Local companies win by being specific, honest, and early.

Build year is the core signal. Homes built before about 1980 often still have single-pane or early aluminum windows, which are the biggest comfort and efficiency upgrade. Homes built from about 1980 to the mid-1990s usually have first-generation double-pane windows, and after 25–30 years the seals commonly fail, letting the insulating gas escape and causing fogging between the panes. Combine build year with long ownership and owner occupancy to find homes most likely to still have their original windows.

Lead with comfort, not just energy savings. Homeowners notice drafts, cold rooms, condensation, and street noise more than a percentage on their utility bill. Copy that names those experiences for a home of their age, and offers an assessment that tells them which windows actually need attention, builds trust that heavy-discount mailers don't.

Compliance is part of the job. For homes built before 1978, the EPA's Renovation, Repair and Painting rule requires lead-safe work practices and a certified firm when disturbing painted surfaces, which window replacement almost always does. Saying you're RRP-certified on mail to older neighborhoods is both required knowledge and a trust signal.

Finally, follow your installations. Neighbors in the same subdivision usually have the same original windows. A card after each install, mentioning the nearby project without naming the customer, gives the street a real local reference and a reason to book.

Expect a longer decision cycle than most trades. Homeowners often scan a window postcard months before they're ready to buy, waiting for a tax refund, a bonus, or the end of winter. Keep owners who scanned on a light follow-up schedule so your company is still the first call when they're ready, and re-mail past estimates every six months.

Questions from window & door companies

How do I find homes that need replacement windows?

Use build year as a proxy for window age. Owner-occupied homes built before the mid-1990s and owned 10+ years are the most likely to still have original windows. Pre-1980 homes often have single-pane or aluminum frames.

How do local window companies compete with national brands?

Be specific and honest. Mail a card that names the home's age and the likely issue, offer an assessment instead of a same-day discount, and follow up quickly on every scan. Homeowners notice the difference.

Do I need to be lead-safe certified for window replacement?

For homes built before 1978, the EPA's RRP rule generally requires a certified firm and lead-safe practices when work disturbs painted surfaces, which window replacement usually does.

Can I target entry and patio doors separately?

Yes. Run separate campaigns: entry doors for long-time owners focused on curb appeal and security, and patio doors for homes built in the era of older aluminum sliders.

What does Spur cost for a window company?

Solo is free forever with no card. You pay per postcard when you mail. Team is $49/mo billed annually with more searches, enrichments, QR codes, and lower postcard pricing.
