Your name on every quote

Your homeowners want instant answers.
Most contractors take 2–3 days to quote.

That window closes fast. Homeowners who don’t hear back in hours are already talking to competitors. Every day you wait on a quote is a lead you may lose.

⏱️

Hours become days

Manual quoting takes time — measuring, pricing, formatting. Meanwhile, the homeowner got a response from someone else.

📉

Cold leads don’t close

A quote sent 48 hours after inquiry has half the close rate of one sent same-day. Speed signals professionalism.

🔁

Back-and-forth kills momentum

Phone tag, texted photos, unclear scope — every friction point pushes the homeowner toward whichever contractor is easiest to work with.

Common questions about window estimate calculators

Everything contractors ask before getting started.

How accurate are instant window estimates? +
WindowQuote estimates are ballpark figures built from current SoCal market pricing for materials and labor. Most estimates land within 15–25% of a final on-site quote. They’re designed to set realistic expectations before the in-home visit — not replace a final proposal. Homeowners who arrive at your site already knowing the rough cost range are more qualified, not less.
What window types are supported by the calculator? +
All major residential window types: single-hung, double-hung, casement, sliding, awning, picture/fixed, bay/bow, and sliding patio doors. Materials include vinyl, fiberglass, wood clad, and aluminum. If you install it, it’s probably covered.
How do homeowners use the window estimate calculator? +
You share your branded quote link with them — via text, email, or from your website. They click it, enter their window count, approximate sizes, type preferences, and material choice. In about 60 seconds they have a professional price range. From there, they can request a formal quote from you with one tap, which sends their contact info directly to you.
Is it really free for contractors? +
Yes. Contractors get a free branded quote link with unlimited estimate generation. No credit card required to sign up. Free will stay free for basic quoting. We earn when the platform adds deeper features — lead management, proposal tools, and integrations — which you can choose to upgrade to or not.
Can I add the window estimate calculator to my own website? +
Yes. Your branded quote link works anywhere a URL works — website buttons, email signatures, Google Business profile, Instagram bio, or a QR code on your truck or job site sign. Homeowners who arrive through your link see your business name prominently on the estimate page.
