Belgium contractor guide: boosting ad spend ROI on Meta

Why most Belgian contractors get poor ROI from Meta ads

The problem is almost never the platform. We see this constantly in our work with renovation and trade businesses across Belgium: contractors run a €20/day campaign with a generic photo, broad targeting, and no follow-up system, then conclude that "Facebook ads don't work here." What they actually proved is that an unstructured campaign doesn't work, which is true everywhere.

The Belgian market has real structural differences that compound this problem. You're running bilingual creative across Flanders and Wallonia, you're operating under GDPR constraints that limit certain audience data, and you're selling jobs that often run €5,000 to €50,000+, where the sales cycle stretches weeks, not hours. A campaign structure built for a €30 product simply doesn't translate.

The good news: those same structural factors, when you account for them properly, give Belgian contractors a genuine cost advantage. CPMs in Western European markets like Belgium run well below U.S. levels, where advertisers pay roughly $23.00 per thousand impressions. That gap means your budget goes further here, if the rest of the system is sound.

What does good ROI actually look like for a Belgian renovation contractor?

The cross-industry average ROAS on Meta sits around 2.79x. For a roofing or insulation company, that number is largely irrelevant. Your benchmark is the economics of your own jobs.

Here's how to frame it correctly:

• Calculate ROAS as revenue divided by ad spend. €4,500 in closed jobs from €1,000 in spend is 4.5x ROAS, or 350% ROI.
• For high-ticket renovation, target a lifetime value to customer acquisition cost (LTV:CAC) ratio above 3x. A client who books a €12,000 roof replacement and refers two neighbors has a very different LTV than someone who books a €1,200 gutter clean.
• Track Marketing Efficiency Ratio (MER), which is total revenue divided by total ad spend across all channels. This prevents Meta from taking credit for jobs that referrals or Google drove.

A 2.5x ROAS on a €500 average job is a thin margin. A 2.5x ROAS on a €15,000 window replacement project is a strong business. The number only means something in context of your average job value and close rate.

For contractors who want to understand how these numbers translate into actual campaign benchmarks, our breakdown of Meta ads ROAS benchmarks for contractors in 2026 goes deeper on what top performers do differently.

How to structure a Meta campaign that actually generates qualified inquiries

Start with one campaign, one ad set, and three to five creatives. Run it on a fixed daily budget, somewhere in the €25 to €50 range, for at least seven to fourteen days without touching it. Meta's algorithm needs that window to exit the learning phase. Every time you change the budget significantly or swap out the ad set, the learning resets and your CPM climbs.

On targeting: broad audiences consistently outperform narrow interest stacks for home improvement. Broad targeting CPMs run roughly $8 to $10, while narrow interest-based targeting pushes $10 to $15. More importantly, Meta's own AI, through Advantage+ placements, is better at finding your homeowner audience than manually stacking interests like "home renovation + homeowner + age 35-65." Let the algorithm work, and save your energy for the creative.

Creative is where Belgian contractors lose the most money. A static image of a finished roof or a before-and-after window photo doesn't build enough trust to move a homeowner toward a €20,000 decision. Video-first creative that shows your crew at work, explains your process, and addresses the homeowner's actual fears (will they be reliable, will the price hold, will it be done on time) reduces the friction of a cold inquiry. The Ramsey Holiday Lights campaign was built around exactly this principle, focusing on trust and authority before asking for any contact, and it delivered 8.9x ROAS in 53 days with 42 high-quality leads.

For Belgian campaigns specifically: split your Dutch and French creative into separate ad sets. Not just translated copy, but creative that reflects the visual and tonal differences between Flanders and Wallonia. Running a single Flemish-style creative across both regions costs you relevance and conversion rate in the south.

Timing and budget decisions that affect your CPM in Belgium

Q1 is the best time to build your pipeline at the lowest cost. Post-holiday ad inventory is cheaper, homeowners are planning spring renovation projects, and your competitors are mostly sitting on their hands waiting for the phone to ring. Q4 CPMs spike across the board as e-commerce advertisers flood the auction, which makes it an expensive time to compete for the same eyeballs.

Practical budget guidance:

• Use daily budgets when you're still in the testing phase. They give you flexibility to pause, adjust, and observe without locking in spend.
• Switch to lifetime budgets once you have a winning creative and a stable cost per lead, so Meta can allocate spend toward the highest-converting time windows.
• Set a cost-per-result goal only after you have at least 30 to 50 conversion events. Setting it too early starves the algorithm before it has enough data.

On lead quality: if you're generating inquiries but they're not converting to booked estimates, the issue is usually upstream in the ad or the landing experience, or downstream in your follow-up. A €50/day campaign with a 30% appointment booking rate beats a €200/day campaign where leads go cold in the inbox. Our guide on improving Meta ads lead quality with Advantage+ covers the specific levers that affect inquiry quality, not just volume.

What a working acquisition system looks like versus a one-off campaign

Most contractors who've "tried Facebook ads" ran a one-off campaign with no qualification layer and no structured follow-up. The leads came in, nobody called them back within the hour, and by the time someone did, the homeowner had already booked a competitor.

A working acquisition system has three connected parts: the ad that generates the inquiry, a qualification step that filters serious homeowners from tire kickers, and a follow-up sequence that moves qualified leads to a booked estimate. Remove any one of those and the economics collapse.

This is the difference between a campaign and an infrastructure. Our client results page shows what this looks like in practice across different home improvement verticals, including a garage door and gate company that generated over 200 inbound requests in three months, with €60K closed in the first two weeks alone.

If you're evaluating agencies or building this yourself, the questions to ask are covered in detail in our piece on how to choose a Meta ads agency for your contracting business.

The core truth for Belgian contractors in 2026 is this: Meta ads don't fail because of the platform or the market, they fail because the campaign is disconnected from a real acquisition system. Knowing this means you stop asking "does Facebook work in Belgium?" and start asking "is my structure, creative, and follow-up actually built to convert high-ticket homeowners?"

Frequently asked questions

What is a good ROAS for a Belgian home improvement contractor on Meta?

A good ROAS for a Belgian renovation or trade contractor on Meta depends entirely on your average job value. The cross-industry Meta average sits around 2.79x, but high-ticket home improvement businesses, roofing, windows, insulation, should be targeting 5x to 10x or higher. A 4.5x ROAS on a €15,000 window project is a strong outcome. The same ratio on a €500 job barely covers costs. Always calculate ROAS in the context of your job value and close rate, not against a generic industry number.

What is the 20% rule on Facebook ads?

The 20% rule was a former Meta policy that penalized ad images where text covered more than 20% of the creative surface, reducing reach or blocking delivery. Meta formally retired this rule, but the underlying principle still holds in practice: heavy text overlays reduce engagement and trust, particularly for high-ticket home improvement where visual credibility matters. Video-first creative with minimal on-screen text consistently outperforms text-heavy static images for renovation businesses targeting homeowners.

Is €25 per day enough to generate renovation leads in Belgium?

Yes, €25 per day is a viable starting budget for testing in Belgium, provided the campaign is structured correctly. Run one campaign, one ad set, and three to five creatives for at least seven to fourteen days without changes. This lets Meta's algorithm stabilize. At this budget, expect to gather enough data on CPM, click-through rate, and cost per lead to make informed scaling decisions. The goal at €25/day is learning, not volume. Scale only after you have a confirmed cost per qualified inquiry.

How does GDPR affect Meta ads targeting for Belgian contractors?

GDPR restricts the use of sensitive personal data in ad targeting and requires a lawful basis for data processing under EU law. For Belgian contractors running Meta ads, this means you cannot use certain health or financial data for targeting, and retargeting website visitors requires a compliant cookie consent setup. In practice, broad audience targeting with Advantage+ placements is both GDPR-friendlier and more effective for home improvement than narrow interest stacks that rely on inferred personal attributes.

Why do my Meta leads not convert into booked jobs?

Unconverted leads almost always trace to one of three problems: the ad attracted low-intent or unqualified homeowners, there was no qualification step between the inquiry and the sales call, or follow-up was too slow. Research consistently shows that leads contacted within the first hour convert at significantly higher rates than those reached a day later. A structured follow-up sequence, not just a single callback attempt, is what separates contractors who close from Meta leads from those who write off the platform entirely.

What is a realistic cost per lead for roofing or insulation in Belgium?

Cost per lead for high-ticket home improvement in Belgium varies by service, targeting approach, and creative quality, but a realistic range for a well-structured campaign is €15 to €50 per inquiry. Roofing and insulation tend toward the higher end because of longer decision cycles and higher homeowner intent thresholds. The more important number is cost per booked estimate and ultimately cost per closed job. A €45 lead that closes at 30% is far more valuable than a €15 lead that closes at 5%.
