Do you have a wiggly switch or jiggly outlet? Or does nothing happen when you use them? Do you see a spark whenever you unplug the vacuum cleaner? You need an electrician!

We have the equipment, and experience, to do just about any electrical repair work. We can replace your wiggly switches and jiggly outlets. We can find the cause of that failure or spark, and fix it.

More than 30,000 people suffer electrical shocks every year. 60 die. Every day, five or more children are treated in hospital emergency rooms for electrical shock or burn injuries caused by tampering with a wall outlet. (Source:

There are many things you can do to be safe around electricity. If an outlet or switch doesn’t work or “feels weird” have it replaced. Any time you see sparks near an outlet, call an electrician! There may be something wrong, such as a reversed wire, that will affect your whole house electrical system. These are rare, but we still find them in older homes, or in cases where repairs were not made by an electrician.

We all know not to dry our hair in the bathtub, or drop the toaster in the dishpan—we’ll get shocked.  Did you know that there’s a special outlet, called a Ground Fault Circuit Interrupter (GFCI) outlet, which will shut the power off to an appliance in less than 30 milliseconds after an accident—before you get electrocuted? These outlets are required in all new kitchens and bathrooms by the National Electric Code. We can change out your old-style outlets with new GFCI outlets to give you the peace of mind they bring.  If your house has older, two pronged outlets (ungrounded outlets), replacing them with specially labeled GFCI outlets will allow you to plug in newer devices while keeping you safe.

If you have concerns about your electrical system, give us a call. William Longo Electric provides products and service you can rely on.

Cape Cod generator sales service installation

Have you been thinking about getting a generator? Whether it’s ice and snow in winter or lightning in summer, losing power in adverse weather is more than just an inconvenience. With an automatic standby generator, you can stay warm in the cold, protect your frozen and refrigerated food from spoiling in the heat, and maintain communication by keeping cellphones and other electronic devices charged and running. With the correct generator you’ll also have enough power for other uses. Safety, communication, and entertainment in the storm and its aftermath. Who could ask for more?


Cape Cod generator sales service installationWilliam Longo Electric is an authorized dealer of best-selling Generac automatic and portable generators. Generac is the most trusted name in residential standby power. With their generators we can provide you with complete whole house, managed whole house, or essential circuit coverage.


Night or day, when the power goes out, a Generac standby generator comes on automatically. It will  also turn itself off when power is restored. They’re wired directly into your electrical system so there’s no need for you to go out into the weather, mess around with extension cords, or deal with anything else. Automatic generators are installed outside the home, keeping your living area clean and quiet. They’re a reliable and worry-free way to protect your family, your home, and your possessions in case of unpredictable power failures.


Generac’s 8 – 20 kilowatt Guardian® Series home standby generators are engineered and built here in the USA, and Generac stands behind them with a strong 5-year limited warranty. One of the most recent of the company’s ongoing innovations is the Mobile Link™ cellular monitoring system that allows you to know the status of your generator, no matter where you are.

William Longo Electric also sells portable Generac generators for emergency or travel. Who says you have to rough it to camp?

We at William Longo Electric provide products and service you can rely on.

Cape Cod home theater system sales installation

Whether it’s the big game or your favorite movie, you can put yourself in the middle of the action with your own home theater system.

As an authorized dealer for top name manufacturers like LG, Velodyne, Samsung, Denon, Onkyo, Boston Acoustics, Definitive Audio, and Sharp, we can wire your home for video and sound. Or take you wireless.

Cape Cod home theater sales installationTo enjoy the movie theater experience from the comfort of your own home, you need three things. The right screen, the right sound, and the right audio-video receiver. We can help you choose what will work best for you, and provide expert installation. Screens should have a clear picture and be at least 27 inches. You’ll need a minimum of four speakers for surround sound.

The biggest difference between the movie theater and traditional home experience is how the sound reaches you. In the theater, sound can “move” through speakers in various locations around the room. In your home, different sounds can come from different areas as the audio signal is split into multiple channels and sent to speakers in the direction from which the action takes place on the screen. This is where the right audio-video receiver comes in. Paired with an amplifier, it receives signals from your chosen input devices (DVD player, DVR, etc.), interprets and amplifies them, and sends them to your screen and speakers.

In-wall and in-ceiling speakers surround you with sound, making you feel part of the action, while keeping your home uncluttered. Check out photos of home theaters we’ve installed for happy customers.

William Longo Electric can provide you with everything you need for an unmatched home theater experience. From speakers to flat screens, we have it all and can bring it to you. William Longo Electric provides products and service you can rely on.
