How to set a mandate before calling your contractor

The problem with emergency repairs

Something breaks. You call a contractor. He arrives, looks around, makes a phone call, tells you he needs parts, and gives you a price. You’re standing in your kitchen with water dripping from the ceiling. You say yes.

He had the initiative. He knew it. You knew it. And you both knew you weren’t going to call two more companies while the ceiling dripped.

This is how most homeowners handle repairs. It’s also how most homeowners overpay.

What a mandate is

A mandate is a budget ceiling you communicate to your contractor before work begins. It works like this:

You are authorised up to EUR ___ to complete this repair. If you expect the cost to exceed that amount, stop and provide a written cost indication and a timeframe for completion before proceeding.

That’s it. One sentence that changes the entire dynamic.

Why it works

For you: If the repair costs less than your mandate, it gets done without further discussion. If it costs more, the contractor has to stop, explain, and get your approval. No surprises.

For the contractor: A clear mandate is actually easier to work with. They know the budget, they can plan accordingly, and their back office can schedule the job properly. Good contractors are used to this — every professional property manager works this way.

If the mandate is exceeded without notice: You now have a reasonable basis to negotiate the invoice. You were clear about your expectations upfront, in writing. That matters.

How to calculate your mandate

The formula is straightforward:

• Labour: Estimated hours multiplied by the local hourly rate
• Call-out / driving: Usually one hour at the hourly rate, or a flat fee
• Materials: Roughly 50% of the total labour cost

Add these up and round to the nearest 25 or 50.

Example

For a plumber in Finland at EUR 65/hour, a half-day job (3-4 hours):

Line item	Calculation	Amount
Labour	3.5 hrs x EUR 65	EUR 228
Call-out	1 hr x EUR 65	EUR 65
Materials	EUR 228 x 50%	EUR 114
Total		EUR 407
Mandate (rounded)		EUR 425

Present the mandate as a lump sum. The breakdown is for your reference — the contractor doesn’t need to see how you calculated it.

When money is tight

Set a lower mandate, but be reasonable. The point isn’t to lowball — it’s to establish boundaries. A mandate that’s too low will simply mean the contractor calls you after 30 minutes to say they can’t proceed. That wastes everyone’s time.

The leverage shift

Without a mandate, the contractor arrives, assesses the problem, and presents you with a price. At that point, your sunk cost is the call-out fee. If you say no, you pay the call-out and nothing gets fixed. The contractor knows this.

With a mandate, you reverse the dynamic. The contractor knows the budget upfront. If they’re confident they can do the job within it, they proceed. If not, they tell you before starting work — and you get a written estimate you can compare with other quotes.

One more thing

When you describe the problem to your contractor, describe the problem, not the solution you want.

Instead of “stop the leak,” say “find and address the cause of the leak.”

This ensures the contractor investigates the root cause rather than applying a patch that will fail in six months.
