Meta Ads vs Google Ads for Window & Door Contractors: Where to Spend Your First Marketing Dollar

“Should I run Meta or Google ads?” is one of the most common questions we get from residential window & door replacement contractors who are about to start running paid traffic for the first time, or are about to fire whoever's running it now. The honest answer is: both, in a specific order, with a specific allocation. The two channels do completely different jobs in your funnel.

The fundamental difference: intent

Google Ads = harvesting demand

When a homeowner types “window replacement near me” or “double hung windows installed” into Google, they have already decided they have a problem and are actively shopping. Your Google ad gets shown because they raised their hand. The intent is high, the volume is bounded by the number of in-market searchers, and the cost-per-click reflects that intent. In the competitive metros we buy in, a click on a contractor term is priced in the high single digits to low tens of dollars. That is our experience of these auctions, not a published rate card; pull your own keyword planner estimates for your market.

Meta Ads (Facebook + Instagram) = creating demand

On Meta, your ad gets shown to homeowners scrolling past dinner photos and friends' vacation pics. They are not searching for windows. They may never have connected the draft in the back bedroom to the heating bill, even though the Department of Energy puts heat gain and heat loss through windows at 25% to 30% of residential heating and cooling energy use. Your ad has to create awareness, then create desire, then capture intent, all in the few seconds before the thumb moves on.

What each channel is genuinely good at

Google Ads strengths for window and door contractors

• Geographic precision. Show your ad only to searchers within your service radius. Easy to control.
• Buyer-intent keywords. “Window replacement Toronto,” “double hung windows installed near me,” “low-e window cost”, these are not browsing queries. These are buyers.
• Local Service Ads (Local Service Ad). The pay-per-lead format that puts you at the very top of Google with a verification badge. Note that the badge changed: Google has moved to a single Google Verified badge for eligible advertisers who complete its screening and verification, and has discontinued the money-back guarantee that used to sit behind the old Google Guarantee badge. If your sales script still promises homeowners a Google-backed refund, rewrite it. Often a high-margin channel when the ideal customer profile fits.
• Branded search defense. When a competitor buys ads against your business name, you bid on your own name to keep that traffic.

Meta Ads strengths for window and door contractors

• Visual storytelling. Before/after window installations, drafty-window pain, energy-savings stories. Google search ads are text; Meta ads are short visual narratives.
• Demographic + interest targeting. Homeowners aged 35-65, in your service area, with home values in your job-size range, married, etc. Far more targetable than Google search.
• Lookalike audiences. Once you have a list of past customers, Meta can build an audience modelled on them. It is the one lever that turns your existing customer base into a targeting asset, which is why we build it as early as the data allows.
• Pipeline-stuffing volume. When you need lead volume for a slow month, Meta has the audience scale Google's in-market search demand can't match.

The order to build them in

For a contractor starting from scratch or with a broken existing setup:

Step 1: Get Google Ads & Local Service Ad running first

Highest-intent traffic, fastest path to first appointments, clearest ROI signal. The ramp time on Google search and Local Service Ad is fast, often within 2-3 weeks of launch you have a working baseline. This gets revenue flowing while the longer Meta ramp is in progress.

Step 2: Stand up Meta retargeting

Even before you run Meta to cold audiences, run Meta ads only to people who've visited your website but didn't convert. This is the cheapest, highest-converting Meta traffic you'll ever buy. It also gives you Meta pixel learnings cheaply before you spend on cold audiences.

Step 3: Meta cold prospecting + lookalikes

Once the pixel has a real conversion history behind it, build a lookalike audience from your past customers and start running cold prospecting on Meta. There is no magic event count that flips the switch; what matters is that the optimisation has enough of your own conversions to learn from rather than learning on your cold budget.

Step 4: Channel-mix optimization

With both channels running, every quarter you re-balance spend toward whichever channel is producing better cost-per-signed-job that quarter. The CAC math has to be tracked per channel, covered here.

The starting allocation that usually works

For a window and door contractor running their first $5K-$10K/mo of paid ad spend in a typical North American metro:

Over time as Meta pixel data matures and lookalike audiences improve, the mix usually drifts toward 40/50/10 or even 50/45/5 in favor of Meta, because Meta's scale is larger once the targeting infrastructure is real. Starting Meta-heavy on day one means paying for the learning period at prospecting prices instead of retargeting prices.

The mistakes that cost contractors the most

1. Running Meta with no pixel data

Spending heavily on Meta cold prospecting before the pixel has seen a meaningful number of your conversions is paying retail for the platform to work out who your buyer is. Run retargeting first. Build pixel data with cheap traffic.

2. Skipping Local Service Ad because “Google's expensive”

Local Service Ads are pay-per-lead, not pay-per-click, and Google's own documentation describes providers as having passed its proprietary screening and verification process. For the window and door accounts we have run, it is routinely among the cheapest sources of signed work, which is our experience rather than a benchmark. Skipping it untested is leaving margin on the table.

3. Running ads to a generic homepage

A Google search ad clicks through to your homepage. The homepage is built for a 50-second skim, not a campaign-specific offer. Conversion rate is abysmal. Real ad campaigns route click traffic through purpose-built landing pages tied to the ad creative.

4. No conversion tracking, no server-side events

Without server-side conversion tracking, you're flying blind on what's actually working. Mobile operating-system tracking-consent prompts broke client-side pixel reliability years ago, and browser restrictions have narrowed it further since. Server-side event forwarding is non-optional now.

5. No phone-call tracking

A large share of window and door leads from paid media arrive as phone calls rather than form-fills, and on a high-ticket in-home purchase that share skews older and more phone-inclined. We are not going to put a percentage on it, because the honest answer is that it varies by market, offer, and creative, and it is measurable in your own account within a month. Without call tracking, whether from a dedicated provider or the native Local Service Ad call reporting, every phone call gets attributed to nothing and your CAC numbers are wrong.

The infrastructure that has to exist regardless of channel

Whichever channel mix you choose, none of it works without the operational infrastructure underneath it:

• Sub-2-minute lead response across both channels. See the speed-to-lead math.
• Pre-qualifying funnel that filters out wrong-fit leads before your sales rep gets involved. See pre-qualified vs raw.
• A2P 10DLC compliance for any SMS automation in the lead- response stack, sitting on top of the federal rules that cap the time to honour a do-not-call request at ten business days and restrict solicitation calls to the 8 a.m. to 9 p.m. window in the recipient's local time. See TCPA / CASL compliance.
• Server-side conversion tracking on both platforms so attribution actually works.

Sources

• Google Local Services Ads Help, the Google Verified badge, which states that Google is discontinuing the money-back guarantee associated with the Google Guarantee badge and that a single Google Verified badge applies to eligible advertisers who complete verification.
• Google Local Services Ads Help, how Local Services Ads work, the source for paying only for leads and for the statement that a verified business has passed Google's proprietary screening process.
• U.S. Department of Energy, home upgrades, the source for heat gain and heat loss through windows accounting for 25% to 30% of residential heating and cooling energy use.
• 47 Code of Federal Regulations section 64.1200, the Federal Communications Commission telemarketing rules, including the 8 a.m. to 9 p.m. solicitation window and the ten-business-day cap on honouring a do-not-call request.

Final thought

Don't pick between Meta and Google. Build both, in order, with the operational infrastructure to convert what each channel produces. The contractors who win the next five years are the ones running a balanced, transparent, properly-tracked channel mix, not the ones “all in on Facebook” or “just doing Google because Facebook didn't work.” Both work. They work together better than either works alone.
