The reputation of the manufacturer

The working method

Builders are increasingly employing works foremen.

The terms of the contract

Only focus on manufacturers offering a individual construction contract (CCMI) based on the law of December 19, 1990. It is the safest contract for owners. It saves you from having to bear an additional cost, even if the costs of materials change during the work.

  • Payment terms ;
  • The delivery time ;
  • Late penalties;
  • A note on the possibility of having you assist at the reception of the house.

The price of the services

It is often the decisive criterion in the final choice of the manufacturer. But beware ! Beware of proposals whose prices are excessively lower than those of the competition. This can hide the use of poor quality materials and / or the employment of low-skilled labor. Keep in mind that a house is made to accommodate you for a long time and that you can sell it later.
