How to tell your contractor what's wrong
Most homeowners describe the solution they want instead of the problem they have. This costs you money. Here's how professionals communicate with contractors — and why it gets better results.
You call a plumber and say: “The kitchen tap is leaking — can you replace the washer?”
The plumber replaces the washer. It leaks again two weeks later. Turns out the valve seat was corroded, and the washer was a symptom, not the cause. You’ve now paid twice.
This happens constantly. And it happens because of a well-intentioned mistake: you described the solution you wanted instead of the problem you observed.
The rule: describe the symptom, not the fix
Professional property managers never tell a contractor what to do. They describe what they see, hear, smell, or feel — and let the contractor figure out the cause.
Instead of this:
“The gutter is broken — please replace it.”
Say this:
“Water is running down the north facade during rain, originating from the gutter joint at the roof edge. The gutter appears intact but the joint area is visibly wet even after rain stops.”
The difference is enormous. The first version tells the contractor what to do (replace the gutter). The second tells them what’s happening and where. Now the contractor investigates, finds the actual cause (maybe degraded sealant, maybe a misaligned section, maybe a blocked downpipe backing up), and fixes it properly.
Why this matters financially
When you prescribe the solution:
- The contractor does what you asked, even if it’s wrong
- You can’t complain about the outcome — you told them what to do
- If the problem recurs, you pay again
When you describe the symptom:
- The contractor is responsible for diagnosing the cause
- If their fix doesn’t solve the problem, that’s on them
- You retain leverage: “I told you the problem. Your job was to solve it.”
This is not a small distinction. It shifts accountability from you to the person you’re paying to have the expertise.
What to include in your brief
A good contractor message has five elements:
-
What you observe — the symptom, in plain language. What do you see, hear, smell? When does it happen? How long has it been going on?
-
Where exactly — floor, room, wall, exterior face. Be specific. “Kitchen” is not enough. “Kitchen, north wall, below the window, left of the sink” is useful.
-
Component details — if you know the brand, model, year of installation, or any error codes, include them. This saves the contractor a site visit just to identify what they’re working with.
-
Your mandate — the budget ceiling. “You are authorised up to €275 to complete this repair. If you expect costs to exceed this amount, stop and provide a written estimate before proceeding.”
-
Contact for access — who to call, when the property is accessible, any access restrictions.
What to leave out
- Your diagnosis. “I think it’s the boiler pump” — unless you’re a heating engineer, this is noise.
- Your preferred solution. “Just replace the whole thing” — let the contractor decide whether repair or replacement is appropriate.
- Urgency pressure. “This needs to be done TODAY” — unless it genuinely endangers people or property (use the 4P rule). False urgency gets you premium pricing for standard work.
The 4P urgency check
Before you call, ask yourself: does this endanger…
- People? Health hazard, safety risk, structural concern
- Pets / environment? Toxic exposure, contamination
- Production? Can’t use the space for its intended purpose
- Possessions? Risk of damage to belongings or the building
If yes to any of these — it’s urgent. Call now. If no to all — schedule it. You have time to get it right.

This template does three things: it gives the contractor what they need to assess the job, it sets a financial boundary, and it shifts diagnostic responsibility to where it belongs.
