What’s happening?

With appkeep, your house has a maintenance plan: what needs doing, what it costs over the years, and which decisions can wait.

§ 01 Is it for me? three moments · in order

It’s for the owner of the house they live in — in Finland, the Netherlands, or Sweden for now. The rest of the EU is next, and the rest of the world after that.

You hand the contractor a budget ceiling, in writing, before work begins.

A mandate is the cap a property manager hands a contractor: hours, local trade rate, call-out, materials. They proceed within it. If the cost will exceed it, they stop and explain why in writing before continuing.

Holding a quote already? Enter it below to see whether it lands in the typical range for the job. Or set the ceiling first: the cap you hand the contractor before any work begins.

This is the tool for a repair you need now: something is broken, and sending a mandate commissions the work under your ceiling. Work that can wait puts you in a stronger position — you have time to make contractors compete on more than price. How to compare quotes for planned work

Without mandate

Jonas calls an installation company. Repairman arrives: €90 call-out. Thirty minutes assessing: €32.50. €125 on the meter before any repair begins.

With mandate

The price is decided before the visit, not discovered after it. Jonas hands the contractor the ceiling. They proceed within it; if not, they stop and write.

Describe the problem, not the solution. You write "find and address the cause of the leak", not "stop the leak". The contractor's expertise is the diagnosis; your mandate is the budget.

  1. Hourly rates above are EU averages for the trade. Adjust to your local market — Dutch and German rates run higher than Iberian and Eastern European.
  2. Materials ratio varies by trade. The calculator applies each trade's figure (plumbing 0.80, electrical 0.50, painting 0.35, roofing 1.0), and they lean generous because the mandate is a ceiling that should cover most jobs. The representative example above uses the general 0.50 default.
  3. Swedish rates show in kronor. We hold sourced ranges for plumbing (900–1,400 kr/h incl. moms, Stockholm) and electrician (650–1,050 kr/h incl. moms); for other trades, enter the rate from a quote or the trade body's published range — the calculator will not invent one.
