30-second summary

  • A home service is marked up with the type dedicated to its trade (Plumber, Electrician, HousePainter…) or, failing that, LocalBusiness.
  • Done well, it helps you get cited by ChatGPT for 'a reliable plumber available tonight near Montreal'.
  • You can reflect availability and services — only if they are true and displayed.
  • Absolute rule: only mark up what is true and visible. No false signal (especially not a fake 24/7 availability).
The key idea The principle of structured data is the same as for a restaurant — we explain it in this guide. The home service has an asset: schema.org offers trade-dedicated types (Plumber, Electrician…), which let you describe your activity and your area unambiguously.

This guide expands on the fourth lever of our pillar article on the Local Pack. It is the most technical, but also the one that prepares the future: as search shifts toward AI answers, providers whose data is structured take a head start.


The right type: by your trade (or LocalBusiness)

The schema.org vocabulary offers types dedicated to many trades: Plumber, Electrician, HousePainter, Locksmith, MovingCompany, HVACBusiness… Choose the one matching your dominant trade. If no precise type exists for your activity, use LocalBusiness, more generic but already much clearer than vague markup.

To this markup, you add the useful properties: the services genuinely offered, the service area (areaServed), contact details, and optionally the average rating — only if it is real and displayed.


The properties that matter for a home service

ElementWhat it describes
nameThe exact business name (consistent with your NAP).
areaServedThe service area (cities and sectors genuinely covered).
makesOffer / hasOfferCatalogThe services offered (unclogging, recurring cleaning, repair…).
telephone / urlThe phone and the site address.
openingHoursThe opening hours (and emergency availability if real).
aggregateRatingThe average rating — only if it is real and displayed.

What it looks like in code

The markup takes the form of a JSON-LD block placed in the page. Simplified example for a plumber (adapt to your trade and your real information):

<script type="application/ld+json"> { "@context": "https://schema.org", "@type": "Plumber", "name": "Your business name", "url": "https://your-business.ca", "telephone": "+1-514-000-0000", "areaServed": ["Montreal", "Laval", "South Shore"], "makesOffer": [ { "@type": "Offer", "itemOffered": { "@type": "Service", "name": "Drain unclogging" } }, { "@type": "Offer", "itemOffered": { "@type": "Service", "name": "Water heater repair" } } ] } </script>

Each value must reflect the reality of your business and match what is shown on the page. This code is a starting point, not a copy-paste: its value comes from accuracy.


Rich results: an asset, not a guarantee

Clean markup makes your information eligible for certain rich displays in Google. But eligible does not mean guaranteed: Google decides alone, based on page quality and data consistency. Beware of anyone promising 'guaranteed stars'. This principle is the same for all businesses — we detail it on the restaurant side.

Getting cited by AI: tomorrow's visibility

More and more clients no longer type keywords: they ask. 'A reliable plumber available tonight near Montreal', 'who can deep-clean before a viewing this weekend' — to ChatGPT, to Gemini, or in Google's generated answers. These systems rely on clear, structured information.

A business whose site exposes consistent Schema provides exactly the data these AIs need to understand it and, where relevant, cite it (trade type, services, service area, availability). It is not a guarantee — no one can promise that — but a total absence of structure makes a business much harder to interpret. This is GEO (generative engine optimization): ground still little occupied by home services.


Mistakes never to make

  • Marking up a rating, an area or an availability absent from the page.
  • Displaying a fake 24/7 availability you don't offer: misleading, and a source of bad reviews in an emergency.
  • Inventing reviews or a rating. Forbidden by Google, risky for your reputation.
  • Not testing: validation tools exist; check before and after publishing.
The golden rule of Schema Only mark up what is true and visible on the page. Structure amplifies your reality — it must never dress it up. For a home service, where you open your door to a stranger, it is also the best long-term protection.

Frequently asked questions — Schema and AI

The schema.org vocabulary offers types dedicated to many home-services trades: Plumber, Electrician, HousePainter, Locksmith, MovingCompany, HVACBusiness, among others. Choose the one that matches your dominant trade; if no precise type exists for your activity, use LocalBusiness, more generic. This is more accurate than a vague type, because it clearly states your trade to Google and AIs. To this markup, you add the useful properties: the services genuinely offered, the service area (areaServed), contact details and, if it is real and displayed, the average rating.

No, and you should be wary of any guarantee. Markup makes your information eligible for certain rich displays, but Google alone decides whether to show them, based on page quality, data consistency and many other factors. Clean markup that is faithful to the visible content puts the odds in your favour, without guaranteeing anything. Conversely, markup describing information absent from the page (a rating, an area or an availability that is not there) may be ignored, or even deemed misleading. For a trust sector like home services, the rule is clear: only mark up what is true and visible.

AI assistants build their recommendations from clear, structured information. When a client asks for 'a reliable plumber available tonight near Montreal', the AI relies on sources that unambiguously describe the type of business, the services offered, the service area and the trust signals. A business whose site exposes consistent Schema (trade type, services, area) provides exactly that data, which makes it interpretable and, where relevant, citable. It is not a guarantee of being named, but a total absence of structure makes a business much harder for an AI to understand. It is still little-occupied ground among home services — an advantage to take early.

You can describe your services, including emergencies, in your site content and reflect them in the Schema (for example via the services offered and the hours), provided this information is true and displayed on the page. Never mark up a 24/7 availability you don't actually offer: it is misleading and, for a client in an emergency, a source of disappointment and bad reviews. The goal of markup is to amplify a reality, not dress it up. Used well, it helps Google and AIs understand that you are available and relevant for an urgent request — a real asset when the information is accurate.

Yes, but only if they are real and displayed on the page. Review markup must never invent a rating or include reviews absent from the site. Google explicitly forbids marking up fake reviews, and it can lead to a penalty. The rule applies to all Schema: what is marked up must correspond exactly to what the visitor sees, whether it is a rating, a service area or an availability. For a home service, whose reputation is the main asset, this honesty is also the best long-term protection: a single false signal spotted can cost far more than the small gain hoped for.
