"Will never use or recommend John C. Flood whose business strategy is fleecing customers. First thing to know is they send a link from an outfit that filters bad reviews once you pay, so only the good ones are actually posted. IGNORE the amount of positive ratings, the bad ones get lost. Second thing to know is this is one of the many ?local? companies that probably formerly provided great service at a reasonable cost unfortunately bought by a private equity company to squeeze the last drop of blood out of the turnip to benefit themselves while delivering no value to customers. I had an electrical issue for a tenant occupied property. Tenants are good and try to figure easy issues out, but could not. I suspected it was an easy issue and scheduled a 12-5 window with John C. Flood to check it out. They said a $99 service charge for a visit. Problem #1 - I get a text and phone call before 8 a.m. they?re on the way. Keep in mind this needed to be scheduled with tenants and it was schedul"

Hello future friends and clients. I am a commercial and residential electrician with16 years’ of experience. I absolutely love what I do and I am an insured, licensed Electrical Master in MD, VA, and DC. I pride myself on having a company that meets a client’s needs in a timely manner at a reasonable cost. We have become an example of quality work, superb technical skills, and excellent customer service. I am eager to make all your electrical connections and visions come to life. It may sound tempting to DIY electrical work, but it is usually not the safest option. Before you know it you have caused bigger problems that will cost even more money. Let my company do your electrical work safely. Whether you need major renovations, or a simple light change I can help. I am bilingual (Spanish/English). My goal is to make you smile at the completion of every project.

"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 Annandale, VA

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.
