Windows & Doors Growth Hub

Window replacement leads typically cost between $80 and $350 per lead, depending on the market, channel, competition, and how well the campaign is qualified.

Google Ads usually produce the highest-intent leads but at the highest cost. Facebook and other paid social channels often generate cheaper leads, but they require stronger qualification, faster follow-up, and tighter sales processes to convert reliably.

Cost per lead alone is not the right metric to judge performance. A $250 lead that turns into a $12,000 job is more profitable than a $75 lead that never closes. What matters more is cost per booked appointment and cost per sale.

In most cases, rising lead costs are not the real problem. The breakdown usually happens after the lead comes in. Slow response times, weak qualification, inconsistent follow-up, and poor visibility into which leads convert create the illusion that leads are “too expensive.”

For window companies, improving close rate and appointment quality often reduces acquisition costs more effectively than switching channels or increasing spend.

A healthy cost per sale for window companies typically falls between 8% and 15% of total job revenue.

For example, on a $10,000 window replacement project, total marketing and sales costs should ideally land between $800 and $1,500. Companies prioritizing aggressive growth may temporarily accept higher costs, while companies focused on profitability aim for the lower end of that range.

If your cost per sale feels too high, the issue is rarely lead volume alone. It is usually driven by low close rates, poor appointment quality, or inconsistent follow-up after estimates.

Small improvements compound quickly. Increasing close rate by even 5–10% often has a larger impact on profitability than generating more leads at the same cost. The most efficient window companies monitor cost per sale weekly and adjust follow-up, qualification, and sales discipline before increasing ad spend.

Most window companies do not have a lead problem. They have a system problem.

Common breakdowns include slow response times, no qualification before appointments, inconsistent follow-up after estimates, and no visibility into which leads actually convert into sales. When every lead is treated the same, sales teams waste time on low-intent prospects and miss high-intent opportunities.

Leads decay quickly. Response delays of even 10–15 minutes significantly reduce booking and close rates. Without structured follow-up, many homeowners who initially show interest simply move on to the next company.

The fix is rarely “more leads.” It is usually better speed-to-lead, clearer qualification, consistent follow-up, and basic tracking that shows which sources and appointments produce revenue. When those systems are in place, close rates often improve without increasing marketing spend.

Google Ads delivers faster results. SEO lowers costs over time.

 

Google Ads works best when immediate demand and predictable lead volume are priorities. It allows window companies to appear at the top of search results for high-intent keywords right away, but costs increase as competition rises.

 

SEO takes longer to produce results, but it compounds. Over time, strong local SEO and service-based content reduce reliance on paid ads and lower cost per lead. SEO also builds credibility and trust with homeowners researching major replacement decisions.

 

High-performing window companies typically use both. Google Ads capture demand now. SEO builds long-term stability and cost control. The right mix depends on market competitiveness, budget, and how quickly the company needs results.

 

A strong close rate for qualified window replacement appointments is typically between 25% and 40%.

Close rates below 20% usually indicate poor lead quality, weak appointment setting, an inconsistent sales process, or a lack of follow-up after the first visit. Close rates above 40% are possible but usually reflect strong qualification, disciplined sales execution, and well-matched leads.

Improving close rate creates leverage. Increasing close rate by 5–10% often drives more revenue than increasing lead volume, without increasing marketing costs. Most window companies focus too heavily on generating more leads instead of improving how effectively existing opportunities are converted.

Close rate should always be reviewed alongside appointment quality and cost per sale, not in isolation.
