Marketing agency or in-house marketer: what's best for an Australian construction company?

By Michael Lyons, Constructiv Digital. Last updated 3 November 2026.

For most small and medium Australian construction companies, a specialist marketing agency for builders gives you more skills for less money than one in-house marketer. A full-time hire typically costs $85,000 to $160,000 a year once super, leave and tools are added, and one person rarely covers SEO, Google Ads, web, content and CRM. In-house makes sense once you need daily content and have budget for agency support too.

Below we compare the real costs, the skills gap, when each model fits, and the questions to ask any agency before you sign.

How do the costs compare?

The salary is only part of an in-house hire. Super, leave, software and management time add up quickly. Here's a side-by-side view for 2026.

Indicative 2026 ranges, excluding GST and ad spend. The super guarantee rate is 12% from 1 July 2025; see the ATO's super for employers guide.

What skills can one in-house marketer cover?

Construction marketing now spans at least six disciplines. It's rare to find one person who is strong at all of them:

• SEO, including technical fixes, service and location pages, and AI search visibility.
• Google Ads, including keywords, negative keywords, bidding and conversion tracking.
• Website design and development, including landing pages, speed and conversion.
• Content, including project case studies, capability statements and tender material.
• Social media and video, including LinkedIn for commercial work and Facebook or Instagram for residential.
• CRM and lead handling, including follow-ups, lead source tracking and reporting.

A good in-house marketer is usually strong in two or three of these and relies on outside help for the rest. That's not a failing; it's the reality of the role.

When does an in-house marketer make sense?

In-house is usually the right call when:

• You need daily content from site, such as progress photos, social posts and project updates.
• You run several brands, divisions or display homes that need constant coordination.
• Your annual marketing budget, excluding ad spend, is well above $150,000.
• Someone senior in the business can manage and develop the role.

Even then, most in-house marketers still use agencies or freelancers for specialist work like SEO and Google Ads.

When does a specialist construction agency make sense?

An agency is usually the better option when:

• You want results across several channels without hiring several people.
• You need experience now, not after a new hire learns the industry.
• You want continuity, so marketing doesn't stop when someone resigns or goes on leave.
• Your buyers include procurement teams, head contractors or government, where tender language and compliance matter.

This combination of industry knowledge and specialist marketing expertise can deliver measurable results. For example, our case studies highlight a 122% increase in website traffic for Waratah Supplies over six months and 193 paid search conversions for The Advanced Group in its first six months.

Is a hybrid model the best of both?

For many growing builders and contractors, yes. A common hybrid looks like this:

1. An in-house coordinator captures site photos, manages social media, collects reviews and briefs the agency on new projects.
2. A specialist agency handles SEO, Google Ads, website updates, content and reporting.
3. A monthly meeting reviews leads, jobs won and next month's priorities.

This keeps the knowledge of your projects inside the business while giving you a full team's skills.

When is an agency not the right choice?

An agency isn't always the answer. It may not suit you if:

• Your pipeline is full for the next 12 months and you're turning work away.
• You win nearly all your work through a small number of long-term relationships.
• You can't commit any budget beyond three months, because SEO and content need time.
• You aren't able to give an agency access to project photos, staff time or feedback on leads.

In those cases, a few hours of freelance help or a one-off website refresh may be enough.

What questions should you ask when selecting an agency?

Use these questions to compare agencies, including us:

1. What construction clients have you worked with, and can we speak to one?
2. How do you report on leads and jobs, not just traffic?
3. Who will work on our account, and what's their experience?
4. What's the minimum term, and what happens to our website and content if we leave?
5. Do we own our Google Ads, analytics and Google Business Profile accounts?
6. How are you adapting our marketing for AI search tools like ChatGPT and Google AI Overviews?

Frequently asked questions

Is it cheaper to hire a marketing agency or an in-house marketer?

For most small and medium construction businesses, an agency is cheaper. A retainer of $2,000 to $8,000 a month covers several specialists, while an in-house hire often costs $85,000 to $160,000 a year all in.

What does a construction marketing agency do?

It plans and runs your marketing across channels such as SEO, Google Ads, website, content and social media, with reporting tied to leads and jobs won.

Can I use an agency and an in-house marketer together?

Yes. Many builders use an in-house coordinator for site content and social media, and an agency for specialist work like SEO and Google Ads.

How long should I give an agency before judging results?

Give Google Ads one to three months and SEO six to twelve months, but expect clear monthly reporting from the start.
