Improving your electrical system sure does adds value to your house but the relationship value- amount of money spent on improvements is not always directly proportional. In order to make an overall calculus and decide the degree of added value, you have to take into consideration the following:
* the current value of your home;
* the total costs of the improvement work;
* the projected value of your house after performing these improvement jobs.

Nonetheless, knowing accurately how much of the expenditure will be recovered is tough. One thing is for sure, kitchens and bathrooms that have an impeccable electric system ensure a return of their costs when selling the house. Another aspect to have in mind when executing a job for the improvement of the electrical system is to add as many receptacles as possible. The principle of convenience works well when discussing the added value of your house, because the next owners think "it is better to have too many than to have too few".

Estimating the costs of the job requires to first draw a list of the components required by the respective task. When going to the store, look at different box sizes and fixtures. Depending on your project, the list should include more or less:
* switches and receptacles;
* cable, noting different gauges;
* electrical boxes (it is recommended that you purchase the biggest your wall can accommodate);
* circuit breakers;
* cover plates;
* appliances (disposer; dishwasher etc.);
* light fixtures;
* wire nuts, light bulbs and electrical tape.

When purchasing things like cable, do it after the principle "the excess is good" as you might need some for your future projects too. When renting tools for the electrical jobs, make sure that the space is ready for use all at once because the working kit is recommended to be leased for as little time as possible.
