When you hire a professional to carry out a work in your home and that person does not carry it out as agreed in the contract, you can sue him in a civil court to comply with the terms provided or repair the damage he has caused.
As you can see, the contract, the invoices and the estimate are necessary for you to have a successful process. A claim for work done badly is based on the initial agreement between the parties and you will hardly be able to object to it if you do not have a written reference of what was to be done.
So be cautious. Make quotations and contracts that explain the details of the work and the scope of the project when you are going to carry out work on your home. This will protect you when it comes to claiming for bad work in court.
The contractor is responsible for the works, but there may be other actors involved such as the company's liability insurance. This may include some parameters for a claim for poor workmanship. In addition, the claimant must try to prove that the work was indeed poorly completed or delivered in a defective condition.
Usually there is also an expert witness who submits a report on the work. He has to be an expert in construction matters and his function is to determine whether the workmanship is in accordance with the contract and whether the intended functionality was achieved.
In addition to this, in order to denounce a badly done reform, you must have the support of a lawyer who drafts the complaint against the professional and takes the case to the civil court of the corresponding locality.
This process can take up to nine months and will probably cause you some inconvenience. However, it is advisable to seek redress before trying to modify the work yourself or hiring another company and incurring further costs. Also be aware that there are time limits and deadlines for claims.
Many cases can fall under a claim. For example, you contracted to replace a bathtub with a shower tray and the work has not been properly executed. Perhaps the materials were placed in an inadequate way and, as there is also water circulation, leaks or leaks occur. In this case, the claim can proceed because inadequate materials were used or because of defects in execution.
But your case may have larger dimensions. You contract an integral reform with floors, new plumbing, modifications in walls, bathroom and kitchen. You probably submitted a project to obtain a building permit and in it you explained the scope of the renovation.
In both cases, the lawyer' s job is to prove that there are differences between what was agreed and the final result. To do so, he will rely on a report or expert opinion. The former sets out the situation - at a cost of around 300 euros - while the latter also looks at the causes and possible relevant repairs as well as the costs of repairs, which can be up to 1.000 euros.
