The short answer: 78% of homeowners hire the first contractor to respond. The door and window installation industry averages 47 hours to first contact. Sub-60-second response achieves a 73% appointment booking rate; 30-minute response achieves 4%. At an $11,000 average job value, every lead your team fails to contact within 5 minutes is likely a lost deal — and at typical lead volumes, that math crosses $500,000 quickly.

Speed to Lead: Why Your 6-Hour Response Time Is Costing You $500K+ Per Year

A homeowner submits a quote request on your website at 2:14 PM on a Thursday. Your team gets back to them at 10:30 AM on Friday — less than 21 hours later. You'd call that a fast response.

They already signed with someone else.

78% of homeowners hire the first contractor to respond. Not the best contractor. Not the most affordable one. The first one. And in a market where your average competitor is calling back at 47 hours, the company that responds in five minutes isn't winning on merit — they're winning on execution.

This post is about what that gap actually costs, and what it takes to close it.

The Industry Average Is Catastrophically Slow — and That's a Competitive Advantage for You

The home services industry averages 6.8 hours to first lead response. Door installation is worse. Field evidence puts the category average closer to 47 hours — nearly two full days between the moment a homeowner raises their hand and the moment anyone responds.

Here's why that's an opportunity: most of your competitors are making the same mistake.

If you respond within five minutes, you're not competing against the industry. You're operating in a different tier than the industry. The homeowner experiences the contrast immediately — one company called back before they'd even finished refreshing their email, and four others are still in their voicemail queue.

The company that calls first shapes the homeowner's expectations, tone, and decision frame. Everyone who calls after is playing catch-up.

The Booking Rate Collapse After 60 Seconds

The data here is not directional — it's decisive. Text responses within 60 seconds achieve a 73% appointment booking rate. Responses after 30 minutes: 4%.

That's not a 10-20% decline. That's a 94% drop in booking rate from a 60-second response to a 30-minute one.

At 47 hours? The homeowner has already forgotten your company's name.

The mechanism makes sense: the window of homeowner engagement is narrow. They submitted the form when the problem was front of mind — they were standing at the door noticing the draft, or they just got home after a particularly miserable December night. By the next morning, they've moved on to other things. Your call interrupts something else instead of meeting a live intent.

Text response at 60 seconds meets them exactly where they are. That's the difference.

What the Math Actually Looks Like

Let's be specific about the cost.

Assume your company:

• Generates 50 leads per month from digital sources
• Has an average job value of $11,000
• Currently responds to leads at an average of 6 hours

At a 6-hour response time, you're achieving something in the 15-20% appointment booking range. Call it 18%, or 9 appointments from 50 leads.

Now model the same 50 leads with a sub-60-second text response:

• 73% booking rate = 36 appointments
• Even at the same close rate (let's say 30%), that's 10.8 jobs instead of 2.7

The delta is 8 additional jobs per month at $11,000 average = $88,000 per month. Annualized: over $1 million.

That number is a ceiling estimate. But the point is that lead response speed is not a minor efficiency gain. It's a different revenue model from the same lead volume.

At realistic scale — 50 leads/month, 6-hour response, 30% close rate — the gap between your current response time and a sub-5-minute response is likely worth $500,000+ annually. Most companies have never calculated it.

Why Most Door Companies Are Still at 47 Hours

It's not that sales teams don't care. It's that lead response at scale requires automation, and most regional dealers are running leads through a person who has eight other things happening.

The common failure mode: leads land in an email inbox. Someone on the sales team checks it at the end of the day. They call the next morning. The homeowner doesn't pick up. The rep leaves a voicemail. Two days pass.

The homeowner has already scheduled with someone else.

The companies closest to cracking this problem are deploying two things: AI-assisted text response (within seconds of form submission, not hours) and automated scheduling links that let homeowners book directly without waiting for a callback. Neither of these requires a large tech budget. Both require a decision to implement.

A Threekit AI agent handles this 24-7. A homeowner who submits a form at 11 PM gets an immediate response - not from a voicemail system, but from an AI agent that can answer product questions, guide them through options, and either schedule the appointment or queue them for a rep callback first thing in the morning. The gap between form submission and first meaningful engagement doesn't exist. Your top sales expert is working every minute of every day.

What Sub-5-Minute Response Actually Looks Like

Here's a realistic implementation:

Step 1 - Immediate text acknowledgment. Within 60 seconds of form submission, a text goes out: "Hi [Name], this is [Company Name] — we got your request. Our next available times are [X] and [Y] — does either work?" No human intervention required.

Step 2 - Scheduling link. The text includes a link to a live calendar. The homeowner books their appointment without waiting for a callback. This is especially important for evening and weekend submissions.

Step 3 - Human follow-up within 5 minutes during business hours. For leads that don't book via the link, a team member calls. The human call is warmer because the text already established contact.

Step 4 - Automated follow-up cadence. If no response to the text within 2 hours, a follow-up text goes out. Day 2, another. The sequence runs without anyone managing it manually.

This is not a theoretical system. It's what companies in adjacent home improvement categories (HVAC, roofing) are already running. The door and window category is two to three years behind.

The One Number to Show Your Leadership Team

If there's one metric to put in front of your CEO, your VP of Sales, or your board, it's this: what is our current average lead response time, and what is the booking rate at that response time?

Most leadership teams don't know their lead response time with any precision. They assume someone is following up quickly because they don't hear otherwise. They're wrong.

Pull a sample. Look at time-stamped lead submissions and time-stamped first contacts. The number is probably not 47 hours — it may be better in your market. But it's almost certainly not 5 minutes, and the gap between 5 minutes and wherever you are is a revenue number worth knowing.

Then ask the follow-up question: what would it take to respond to every lead in under 5 minutes, every time?

That's the conversation that changes the math.

When your rep does call, they're not starting from cold. Threekit's AI Lead Intelligence means the lead arrives with a structured summary - lead score, budget, timeline, products explored. The rep can open with "I saw you were interested in our fiberglass entry doors in the $3K-5K range. I have two options I think will work perfectly." That conversation closes differently than "Hi, you filled out a form on our website."

If you're building toward a website that generates leads with product and budget context already attached - making every response more relevant and every conversation faster - Threekit's AI Agent is the tool designed for that. You can also review what good looks like and how lead quality differs from lead volume for context on how top companies are winning right now.

Frequently Asked Questions

What is the ideal lead response time for door and window companies?

Under 5 minutes for the first contact — ideally an automated text within 60 seconds of form submission, followed by a human call within 5 minutes during business hours. Research shows a 73% appointment booking rate for 60-second text responses versus 4% for 30-minute responses.

How much revenue does slow lead response cost a door company?

At 50 digital leads per month and an $11,000 average job value, the difference between a 6-hour response time and a sub-60-second response is estimated at $500,000 to $1 million in annual revenue from the same lead volume. The exact number depends on your current booking rate and close rate.

Why do most door companies respond so slowly to leads?

The most common failure mode is manual lead management — leads land in email inboxes, a team member reviews them at the end of the day, and calls go out the next morning. At that point, 78% of homeowners have already committed to a competitor. The fix is automation: AI text response and self-scheduling links that don't require human intervention.

Does text response work better than phone calls for lead follow-up?

For first contact, yes. A text within 60 seconds acknowledges the inquiry immediately, asks a qualifying question, and provides a scheduling link — all without requiring the homeowner to answer a call they may not be expecting. Text response achieves 73% appointment booking at 60 seconds; phone calls at the same speed are still effective but require the homeowner to pick up.

How do you calculate the cost of slow lead response?

Multiply your monthly lead volume by your current booking rate and close rate to get monthly jobs. Then recalculate with a 73% booking rate (sub-60-second response) and the same close rate. The difference in jobs times your average job value is the monthly revenue gap. Annualize it.
