All the electrical switches in the house should be insulated properly to avoid any disaster to happen in the house. Insulating can also help in saving electricity and in turn you will get reduced electricity bills.
- The very first step is to switch the power of the circuit breaker as well as of all the equipments off. Ones you have done that test the electricity with the tester to make sure that the circuit is off.
- Now take a screw driver and remove the cover plate and the switch. Now spray the foam amid the walls and exterior rim of the electrical box.
- Now that you have sprayed the foam, take an unused cloth or a piece of cotton to wipe off the extra foam from the walls and the switch.
- Now attach the cover plates and the switches back with the help of a screw driver.
