Home house renovation is completed the renovation company tube I want more money ~ what to do?

You have already finished the renovation, what are you afraid of? Now most of the payment in advance to give work.

Generally speaking, the water and electricity are single-counting, the contract will be written in the unit price how much, according to your actual changes to calculate the cost. (Every home is different, and the difference between a big change and a small change is huge.)

If your contract says utilities are included, then you have even less to fear. If it's written to follow what actually happened, then it's tough. Verbal promises are much less legally efficient than written ones.

Most companies will give you a very low price first, and in the middle they will keep asking questions, and then they will realize that the contract is not written.

In short, the first renovation, most people are going to be ripped off. It is recommended that you negotiate with each other to solve it. Through the law, if you win or lose, not to mention, to involve themselves in a lot of energy, I hope to help you.
