"Amazing. He was here several times, always arrived on time with all materials. Before every job the pricing was discussed and I paid exactly what was agreed upon with no surprises. The electrician was kind, considerate and caring and explained everything to me. He made suggestions and took the time to help me understand everything. I learnt this is a family business and being a small business owner myself It was such a pleasure to have him here. So many companies today you get no personalized attention. He was always reachable by email or phone. I would highly recommend him and will continue to use him."

Electrical questions, answered by experts

If you plan to have a refrigerator or other appliances that require electricity, you will need an electrical outlet in your outdoor kitchen. Be sure to comply with all National Electrical Code® (NEC®) codes for electrical wiring and outlets in kitchens. If you do not plan to install a refrigerator or any other appliances that require electricity as part of your outdoor kitchen features, then you do not need to install electrical outlets. However, it is a good idea to install at least one electrical outlet should you decide to use any appliances that require electricity.

Most upgrades take 1-5 days, depending on building size and wiring complexity.

Unfortunately, a partial power outage without a tripped breaker often means you have a major wiring issue or that the breaker itself is going bad. When the power is out in one room but the breaker is not tripped, you need to call an electrician as soon as possible to identify the cause of the problem and repair it.

GFCI stands for Ground Fault Circuit Interrupter, a standard safety addition to home power outlets. In rooms where moisture is more likely, like the bathroom and kitchen, GFCI outlets stop the current when certain kinds of shorts are detected, preventing shocks. Both GFCI and the similar AFCI (Arc Fault Circuit Interrupter) outlets are polarized and have clear indicators on the receptacle where hot wiring should go.

There are many signs it is time to replace an electrical panel, starting with flickering lights. Other tell-tale signals include overheating appliances, light fixtures that cause an electric shock, hissing or crackling from the breaker box, burned or blackened spots near the breaker box, and breakers that trip whenever activating power-hungry appliances like microwaves.
