Frequently asked questions
What does a plumber charge per hour in Barcelona?
Rates vary between normal service, urgency and night or holiday work, plus the call-out. Always ask for the call-out cost and minimum hour by phone before accepting the visit.
Should I insist on a written warranty?
Yes: any serious repair carries a workmanship warranty and an invoice. The invoice is not a tax on you — it is what lets you claim when the fault returns next week.
Can I fix it myself?
Changing a shower screen seal or a washer is reasonable; touching gas, stacks or electrics without qualification is not, and can void insurance. The exact border: if it can flood or burn when it fails, let a professional do it.
