Why do people have problems with independent repair
They try to abandon all the wishes and save, but in the end they have to overpay for eliminating any defects. At this stage, you are not yet determined with the materials for repair, but only evaluate which work should be carried out, therefore the amount will not be accurate.
The most common cause of unplanned embezzlement is unskilled workers.
After all assessments, correctly plan the upcoming repair process. Sometimes it happens that having agreed with people about payment, they call one value of their services, and already during the repair this amount begins to increase. Repair should begin only if you already have the necessary funds.
