"Job well done- professional and more competitively priced than a more well known name. I trusted what they recommended and did not feel that it was all about making money. I had a new electrical box installed as well as updated the house and installed the exterior shut off. Well done and highly recommend. "

"Mario installed my Tesla wall connector was very flexible. When we decided to wire the connector to an oven plug instead of direct wire, he left to get the plug himself. Great service "

"Do not use this company. They will rip you off. The contract was for eight 300W LED 40 ft pole lights, but I caught them redhanded installing 240W. Who does that? Then, they broke my lock and broke into my sprinkler room which I saw on my video which they admitted. Then, Kolb sued me for not paying the bill which I disputed due to lost tools as result of the break-in. Who does that breaking into a customer's sprinkler room and not informing that they did. I had to catch them on my video. Not only that it took over one year to the work proposed work. TOTAL FRAUD. I will be going to court...."

"I cannot put in words how thankful I am for S&M! To make a long story short, my County Government demanded that my multi-family property be re-wired and brought up to todayâ s code. Iâ ve never needed electrical work done, therefore I searched local Facebook pages and found S&M. During my initial call, Trish thoroughly explained the process and offered to help. I felt comfortable with Trish, therefore took the chance and leaned on S&M to handle this issue. Trish, Ceasar, Kevin and Hugo were extremely helpful and explained all the work that was being conducted. They went above and beyond. They showed up on time every day, were professional, and cleaned before they left. They obtained the needed permits and communicated with the county and their inspectors in order to get the issue resolved in a timely manner. In summary, S&M took control and handled an extremely stressful situation. They had the knowledge, experience and skills to bring my property to todayâ s code. I will highly recommend S&M to anybody who needs electrical work done!"

FAQs for electrical wiring or panel upgrade projects in Knoxville, MD

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
