Window Replacement Google Ads Budget Guide

The short answer

It can be enough for one city or county, and it is not enough for a whole metro. $3,000 a month is about $99 a day. That funds one tightly focused Search campaign, not several markets, several products and several channels at once.
Whether it pays depends on three numbers you already own: average job value, the share of leads that become booked appointments, and your close rate. Use the calculator below with your own figures.
In GoRizen's experience, window replacement leads often cost $80 to $350 each. At that range, $3,000 buys roughly 9 to 38 leads a month, which is about 1 to 5 closed jobs. The spread is wide, so know where you sit before you commit.
Media spend alone can already exceed a healthy cost per sale. In GoRizen's experience a healthy cost per sale runs 8% to 15% of job revenue, and that figure includes sales cost, not just ads. If ads alone take 15% to 20%, the budget is too thin for your job size or your follow-up is leaking leads.
Follow-up often matters more than the budget. In GoRizen's experience, even a 10 to 15 minute delay in responding noticeably lowers booking and close rates. Fix response time before you raise spend. The Lead-to-Job Leak Diagnostic walks through it.

What $3,000 a month actually buys

$3,000 a month buys about $99 a day of Google Ads spend, and that is enough to test one market properly if the account is built for booked jobs. Google sets a campaign's monthly limit at 30.4 times its average daily budget, so a $99 daily budget caps the month near $3,000. On any single day Google may spend up to twice the daily budget, which means a day can run near $197 and a slow day can run under $99. The monthly total is what stays fixed. (Google Ads Help: why daily costs might exceed your average daily budget)

Two cross-checks keep expectations honest.

Published market data. LocaliQ (WordStream) lists the 2026 average for the broad Home and Home Improvement category at a $8.33 cost per click, an 8.05% conversion rate and a $90.92 cost per lead. That is a category average, not a window replacement figure, and impact window keywords in competitive metros can run higher or lower. At those averages, $3,000 buys about 360 clicks and roughly 29 leads. (LocaliQ search advertising benchmarks)
GoRizen's own range. The Windows & Doors Growth Hub states, in GoRizen's experience, that window replacement leads typically cost $80 to $350 depending on market, channel, competition and how well leads are qualified.

To see what a click costs for your exact keywords and city, open Google Ads Keyword Planner, set the location to your service area, and read the top-of-page bid range for terms such as "window replacement near me" or "impact windows cost." That is Google's own auction data and beats any average.

The calculator: from $3,000 to closed jobs

The calculator below turns a monthly budget into expected booked jobs. Every row uses the same steps, so you can swap in your own numbers.

The formulas, in words

Leads = monthly budget divided by cost per lead.
Appointments = leads multiplied by your lead-to-appointment rate.
Closed jobs = appointments multiplied by your close rate.
Cost per closed job (ad spend only) = monthly budget divided by closed jobs.
Ad cost as a share of revenue = cost per closed job divided by average job value.

Worked example. Budget $3,000. Average job value $10,000 (an illustration, use yours). Lead-to-appointment rate 30%, which sits at the low end of the 30% to 35% range reported in the Sunset View Construction case study. Close rate on appointments 25% to 40%, GoRizen's stated range for a strong close rate on qualified window replacement appointments.

Cost per lead	Leads	Appointments (30%)	Closed jobs at 25% close	Closed jobs at 40% close	Ad cost per closed job	Ad cost as % of a $10,000 job
$80	37.5	11.3	2.8	4.5	$1,067 to $667	10.7% to 6.7%
$150	20.0	6.0	1.5	2.4	$2,000 to $1,250	20.0% to 12.5%
$350	8.6	2.6	0.6	1.0	$4,667 to $2,917	46.7% to 29.2%

How to read it:

At an $80 cost per lead, $3,000 works for a $10,000 job even at a 25% close rate.
At $150 per lead, the result depends on the close rate. At 25% you are above the healthy range on ads alone. At 40% you are inside it.
At $350 per lead, $3,000 does not work for a $10,000 job. Either the job value must be much higher, the cost per lead must come down through better qualification, or the budget must be spent on a narrower target.
All figures are expected averages, not guarantees. At 1 to 3 closed jobs a month, a single month will swing a lot. Judge results over at least a quarter.

The most you can pay for a lead

Work backward from what you can afford. The formula, in words: maximum cost per lead = average job value x target cost per sale (as a percentage) x lead-to-appointment rate x close rate.

Average job value	Target cost per sale	Lead-to-appointment	Close rate	Maximum cost per lead
$10,000	15%	30%	25%	$113
$10,000	15%	30%	40%	$180
$10,000	8%	30%	25%	$60
$20,000	15%	30%	25%	$225
$20,000	15%	30%	40%	$360

This is a ceiling for total cost per sale. Because the healthy range includes sales cost, set your ad-only target lower than the ceiling. If your numbers say you can pay $113 per lead and your market delivers leads at $250, adding budget will not fix the gap. Fixing lead quality, the landing page and follow-up will.

When $3,000 is enough

$3,000 a month is a workable budget when most of these are true:

One service area. You advertise in the city or county where you install and close most jobs.
A job value that supports the math. The table above shows $10,000 jobs need a cost per lead near $80 to $150, while $20,000 jobs tolerate more.
Fast follow-up. Every lead gets a text in seconds and a call in minutes, and every lead has an owner in your CRM.
Clean tracking. Calls, form fills and booked appointments are tracked as separate conversions, so you can see cost per booked appointment, not just cost per click.
A landing page that matches the search. Impact windows, sliding glass doors and window replacement each have their own page, with a short form that asks for project type, number of openings and timeline.

When $3,000 is not enough

Be skeptical of the budget if any of these describe you:

You want several cities, several products and Meta all at once. $99 a day split four ways is about $25 a day per campaign, which rarely gathers enough data to optimize.
You are in a very competitive metro. If Keyword Planner shows high bids on your core terms, a small budget buys few clicks and Google gets little conversion data.
Your close rate is under 20%. In GoRizen's experience, a close rate under 20% usually points to lead quality or follow-up, not to the budget. More spend multiplies the leak.
You have no CRM or call tracking. Without them you cannot tell cheap leads from closed jobs, and you will tune toward the cheapest lead.
You need volume fast. Window projects have consideration periods, so jobs from this month's leads often close later. Plan for a lag between spend and revenue.

How to spend the first $3,000

A $3,000 budget goes furthest when you shrink the target and sharpen the offer. This is GoRizen's recommended order, not a formula that guarantees a result.

Start with one Search campaign for your main product and city. Build separate ad groups for impact windows, window replacement and sliding glass doors, and pair each with its own landing page. Add negative keywords for DIY, repair-only, car window and job-seeker searches. See Google Ads for Window & Door Companies That Convert.
Check whether Local Services Ads are available to you. LSAs charge per valid lead, and Google is moving LSA campaigns into Google Ads as a Performance Max campaign type with pay-per-lead goals, in phases running from August 2026 into 2027. The categories Google names for the first phase do not include windows and doors, so check eligibility in your own account. (Google Ads Help: Local Services Ads transition)
Add qualifying questions to your form. Ask project type, number of openings and timeline. In the Supreme Windows case study, adding qualification questions, accepting short-term drops in raw lead volume and shifting budget toward Google Ads went with an 18% decrease in cost per lead and more than a 50% decrease in cost per sale in 2024.
Track three conversions: calls, forms and booked appointments. Then send closed jobs back from your CRM. Start with a simple bid strategy and move to Target CPA only once conversion volume supports it. GoRizen's Google Ads post cites Google's guidance of evaluating Target CPA over 30 days with at least 30 conversions. At 20 leads a month, you may not reach that for a single campaign, so start simpler.
Review search terms weekly. In a small account, one wasted query category can take a noticeable share of the month.
Hold Meta until Search is working. Meta builds demand earlier in the decision. Add it when Search produces booked jobs at a cost per closed job you accept, and fund it separately.
Review at 30, 60 and 90 days by cost per booked appointment and cost per closed job. Raise the budget only when the cost per closed job holds as spend grows.

If you sell impact windows in a hurricane market, add a seasonal layer on top of this plan. See our impact windows hurricane marketing playbook.

Raise the budget or fix the funnel first?

Raise the budget when cost per closed job is inside your target, follow-up is fast, and Google is limiting your delivery. Fix the funnel when leads are cheap but few close. In GoRizen's experience, increasing close rate by even 5 to 10% often has a larger impact on profitability than generating more leads at the same cost.

Symptom	Likely cause	First move
Plenty of leads, few appointments	Slow follow-up or weak qualification	Faster first response, form questions
Appointments, few sales	Sales process, price presentation, financing	Review lost-deal reasons in the CRM
Few leads at a high cost per lead	Budget spread too thin or low-intent keywords	Narrow to one market, tighten keywords and negatives
Good cost per closed job, spend capped	Budget is the limit	Add budget in steps and watch cost per closed job

What agencies and in-house teams cost on top of the budget

The $3,000 in this guide is ad spend. Management is a separate cost whether a person on your team or an agency runs the account. GoRizen's bundled growth plans run from $3,400 to $16,000+ per month by company size, starting at $3,400 a month for companies with $1M to $2M in annual revenue, and standalone paid ads management starts at $2,500 a month. These prices do not include ad spend, which is billed separately. See GoRizen pricing for what each plan includes. For the full agency versus in-house comparison, see Agency vs In-House for a $5M Home Service Company.

If your revenue is near $1M to $2M and ads are the only lever you want, paying management on a $3,000 budget can consume a large share of the return. Run the calculator with the management fee added to the budget before you decide.

Proof: what the numbers look like in practice

These are GoRizen client results from the live case studies page. They do not predict your result. For hurricane-market examples, including STS Impact Windows & Doors, see the impact windows hurricane marketing playbook.

Sunset View Construction: in 4 months, 700+ inbound leads, 140+ sales-qualified opportunities and 40+ closed sales, a 30% to 35% lead-to-appointment rate, and peak months of 12x to 26x return on ad spend. The case study notes these are peak-month and multi-touch figures on high-ticket projects with longer buying cycles.
Supreme Windows: in 2024, a 300% increase in lead volume, an 18% lower cost per lead and more than a 50% lower cost per sale, with paid media spend down 11% quarter over quarter.

FAQ

Is $3,000 a month enough for Google Ads for a window replacement company?

It can be, for one city or county and a job value near $10,000 or more, if follow-up is fast and tracking is clean. At GoRizen's stated range of $80 to $350 per lead, $3,000 buys roughly 9 to 38 leads a month. Use the calculator above with your own job value and close rate before you decide.

How much should a window company spend on Google Ads?

Set the budget from your numbers, not a percentage. Work backward from the cost per sale you can afford: in GoRizen's experience a healthy cost per sale for window companies is 8% to 15% of job revenue. Then check that the budget is large enough to collect conversion data in your main market.

How many leads will $3,000 a month produce?

It depends on your cost per lead. At $80 per lead, about 38. At $150, about 20. At $350, about 9. Published category benchmarks and your Keyword Planner bid range will show where to expect to land.

Why did my Google Ads not work for my window company?

The usual causes are leads that do not qualify, slow follow-up, a landing page that does not match the search, or tracking that only counts form fills. In GoRizen's experience a close rate under 20% points to lead quality or follow-up before budget. Start by reviewing search terms, form questions and response time.

Should I use Local Services Ads instead of Search?

Test both where you can. LSAs charge per valid lead rather than per click, but the categories Google names for its Local Services Ads transition do not include windows and doors, so confirm eligibility in your own account. Many companies run Search first because they control keywords, landing pages and conversion tracking.

How long before I see results from Google Ads?

Leads can arrive in days, but closed jobs lag. Window projects have a consideration period, so judge results over at least a quarter by cost per booked appointment and cost per closed job. Google's help pages advise giving Performance Max campaigns one to two weeks, and up to six weeks at low volume, before major changes.

When should I increase my Google Ads budget?

When cost per closed job is inside your target, response time is fast and Google is limiting delivery. Raise the budget in steps and watch whether cost per closed job holds. If it climbs as spend grows, fix qualification and follow-up first.

Does GoRizen manage window companies' Google Ads?

Yes. GoRizen runs Google Search, Local Services Ads, Performance Max and Meta campaigns for window and door companies, and reports on booked jobs and cost per closed job. Ad spend is billed separately from GoRizen's fees. See Paid Ads Management and pricing.
