"Very professional. Took as much time as needed to answer questions. Very good attention to detail. Even though a few more rods were needed than originally quoted, they stuck to their original quote price. No surprises. I would highly recommend this company."

I’m an old-fashioned, affordable, honest handyman. I am very versatile. \n\nI have worked in construction for over 25 years. I have extensive experience in drywall repair, trim and carpentry work, electronic containment fences and custom pet doors (I can put one anywhere- glass door, window, wall, etc). \n\nThere’s absolutely no job that I won’t at least take a look at and give my honest opinion. No job is too small. No job is too odd. I can do light car maintenance or complex home repairs. Clean-up or Custom work. Just ask! \n\nFlexible hours. Weekends available.

Electrical questions, answered by experts

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

The National Fire Protection Association reports that almost half of reported electrical fires are caused by electrical distribution and lighting equipment. The main culprit behind these fires is often frayed, worn, or faulty wiring, particularly in closed-off and concealed areas like attics, where fires can start and burn undetected for long periods.

Just as fluorescent lights are more efficient than incandescent lights, LED lights are more efficient to run than fluorescent lights. The specifics will vary from product to product, but LED lights are typically twice as efficient as equivalent fluorescent lights. A 13-watt CFL bulb can replace a 60-watt incandescent bulb, but a 6- to 8-watt LED bulb can offer the same amount of brightness. Fluorescent lights offer about 50 lumens per watt, while LEDs offer about 100 lumens per watt. LED light bulbs typically last two to three times as long as CFL bulbs, too. 

Yes, a water leak poses a major fire risk at your home because water is a conductor of electricity. Water that comes into contact with sparks or electrical wires can instantly ignite flammable materials. Additionally, any type of exposure to water can cause wires and other electrical components within your home to corrode. When assessing categories of water damage, it's important to know that even a small amount of moisture near wiring could cause sparks that lead to a fire.
