Wired Installations, LLC is a multimedia services/installation company offering Structured Wiring, Commercial and Residential services, Networking, Audio, Video, Surveillance/Security and alternative Custom Installation services such as media cabinets, built-in shelving, or fireplace mantels. We do offer sub-contracting services throughout the Charleston area. Residential clients may receive a free consultation prior to any installation services requested.

"Probably some of the best customer service and work I’ve ever had done. From the first phone call to Wired Installations, through the work, and finally to when the last tv was hung everything went smoothly. All of this was done with patience and good old experience. My first contact with Matt (the owner) was when I called to ask about hanging a couple of tv’s on the wall. After discussing the locations, he felt this would not be an issue. He asked if we had purchased the tv’s yet – which we hadn’t, and in turn he replied I will match anyone’s legitimate price. I certainly could not go wrong there. He and Marcus showed up on time with my 2 new tv’s and began unboxing and locating them to their respective rooms. Two hours and some change later both tv’s were up and producing a good evenings worth of entertainment. I would highly recommend Wired Installations for any tv installation, or anything electronic. Thanks for such a GREAT experience!"

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

Straightline Remodeling is a hands on company and sub contracts very little. Billing is straight forward, payment is due when job is complete. If it is a large job I take draws along the way.

Electrical questions, answered by experts

Short circuits can cause fires, electrical burns, and electrocution, which can lead to serious injury or even death. That’s why it’s important to take preventative measures to prevent short circuits, like getting annual electrical maintenance and an electrical inspection every two to five years, depending on the age of your home.

You can certainly talk with electricians about pricing, but the pro has the first and last word on what they charge. If you feel like a quote is too expensive, you can discuss the quotes that other electricians have made and see if they’ll lower their estimate in return. Or you may be able to talk about specific parts of the estimate and how they can be changed. 

When wondering what size of breaker for a water heater is appropriate, the majority of hot water heaters need a 30-amp, two-pole breaker. Most residential water heaters use 240 volts and between 3,500 and 5,500 watts. If your appliance matches these measurements, a 30-amp breaker is likely perfect. Owners of point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts often find that a 30-amp breaker is adequate. Water heaters that use more watts than average may need a 40-amp breaker. Smaller units that use fewer watts could potentially use a 20-amp breaker.

For most applications, you won’t need a neutral for 240V. There are certain codes and regulations that differ between areas so just because you technically may not need one in order for the device to function properly, it may still be a local requirement. Professionals in your area know the requirements, which is just another reason to hire one instead of taking on a project that is frankly not very DIY-friendly.

Daisy-chaining refers to placing multiple GFCI outlets in a row along the same circuit. This won’t do any harm, but it’s of limited usefulness because a properly-placed GFCI can monitor all downstream outlets on its own. Multiple GFCI installations won’t usually increase safety except in special cases.
