FILL YOUR CALENDAR WITH
booked estimates.
The Ad-to-Estimate System that turns ad spend into qualified, on-the-books estimates for window installation companies ready to scale past seven figures — and you only pay per estimate delivered.
We only work with window installers. That's it.
[Replace with your real founder story: what you saw window installation companies struggling with — wasted ad spend, unqualified leads, agencies that didn't understand the trade — and why you built a system paid on estimates booked, not clicks or impressions.]
When you work with WindowSpark, you're not another account number in a queue. You're working directly with a team that lives and breathes window installation lead generation.
Two systems that keep your estimate calendar full.
The Ad-to-Estimate Funnel
Google & Meta campaigns built specifically to move a homeowner from "just browsing" to a booked estimate on your calendar — not just a form fill that goes nowhere.
- High-intent targeting for window replacement homeowners
- Estimate-first landing pages, not brochure sites
- Automated booking + reminders so estimates show up
Pay-Per-Estimate Pricing
You don't pay for clicks, leads, or "impressions." You pay only when a real, qualified estimate hits your calendar — so the risk of wasted ad spend is on us, not you.
- No retainers tied to guesswork
- Transparent cost-per-estimate reporting
- Scales up as your crew capacity grows
How we turn ad spend into a full estimate calendar.
We map your numbers
Average ticket, close rate, service area, and current lead sources — so the system is built around your real economics, not generic assumptions.
The funnel goes live
Estimate-first landing pages, tracking, and your first campaigns launch to start booking estimates immediately.
We double down on what books
Budget shifts toward the highest-converting channels and service areas as real cost-per-estimate data comes in.
New territories, same system
Once your core market is booked solid, we expand the funnel into adjacent service areas to push you toward multi-7-figures.
Most lead-gen companies aren't built for window installers. We are.
