Complaint to a tradesperson — enforce your warranty rights
Create your complaint letter to a tradesperson in seconds. The AI drafts a professional letter about defective work, excessive invoices, or scheduling delays.
Important Tips
- Report defects immediately in writing and document with photos
- Set a reasonable deadline for repair (Section 634 BGB), usually 14 days
- Do not pay the full invoice immediately — withhold a reasonable amount as leverage
- For excessive invoices: the cost estimate is the upper limit (max. 15-20% overrun without consent, Section 650 BGB)
Notice Period
The warranty period for tradesperson work is 5 years for building work (Section 634a para. 1 no. 2 BGB) and 2 years for other work. Warranty claims begin with the acceptance of the work.

Frequently Asked Questions
What rights do I have for defective tradesperson work?
Under Section 634 BGB, you are entitled to repair, and after two failed attempts, to a price reduction or contract withdrawal. You can also claim damages (Section 634 no. 4 BGB). You may withhold part of the invoice until the defect is remedied.
What can I do about an excessive tradesperson invoice?
If a cost estimate was provided, it may only be exceeded insignificantly under Section 650 BGB (usually max. 15-20%). For significant overruns, the tradesperson should have informed you in advance. Without an estimate, you owe the customary fee (Section 632 para. 2 BGB). Request a detailed breakdown.
How long is the warranty period for tradesperson work?
For building work (e.g., heating, plumbing, roofing), the limitation period is 5 years from acceptance (Section 634a para. 1 no. 2 BGB). For other work (e.g., repairs), the period is 2 years. Acceptance of the work is the starting point for the warranty.
