Housing

Additional work and associated prices should be agreed on in writing. This is in the interest of both the consumer and the business.

Particularly in renovation work done on old buildings there is the possibility of unexpected complications during work that even a professional contractor could not foresee. 

• The contractor must agree with the customer on undertaking unexpected additional work. The contractor may not undertake additional work and charge for it without the customer's permission.
• If the consumer wants additional work or changes to the work originally agreed upon, he must be prepared to pay for them.
