Action Professional Window & Gutter Cleaning Service Inc. has served Madison and the Dane County area for over 30 years. We provide a variety of services for homeowners and businesses. We specialize in professional gutter cleaning and repair along with installing gutters covers that come with a 5-year warranty on parts AND LABOR. We clean siding and remove graffiti and grime from most any structure. We also pressure wash decks and fences. Let us also quote your snow removal needs too. Our top priority is providing full and complete customer satisfaction.

"This is an outstanding business and I would highly recommend them. I hired them several years ago to power wash my sister's huge house which was filthy on the outside. The team hand washed the whole house and worked so hard in 90 degree heat. They took a lot of pride in their work and did an outstanding job. The neighbors would walk by the house afterward and would not be able to put their hand on why it looked so good and when I told them it was because of the power wash that was done they wanted to know who did the work so they could make note of the company if they needed work done in the future. They have also done numerous gutter cleanings on my house and are reasonable priced, very professional, and do a very thorough job. The rep even made sure to get some of the dust from the shingles that had been in my gutter for a while scraped off so that it would not build up even further. I have never had a gutter company do that! I give this company my highest compliments. They are a pleasure to do business with."

Electrical questions, answered by experts

It’s generally not recommended to run electric to a shed above ground, and you should instead run electric lines underground via a conduit. This job, like all electrical jobs, is best left to a pro, as they’ll need to ensure everything is installed safely and that they don’t run into any other utility lines underground. 

Most electric water heaters have a built-in shut-off switch, so you can simply turn that to the OFF position. Some water heaters have the switch inside a panel, so you might need to unscrew the panel, remove it, move aside the insulation, and then shut the water heater off. To make sure it’s off, you can also locate the switch for your water heater in your electrical panel and shut the power off there. Most electrical panels have dedicated switches for the water heater, so you can shut off the power without affecting the rest of your home.

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

When installing an outdoor outlet, it's important to proceed with caution. Unless you have the necessary training and licensure, it's not recommended to attempt this DIY. First, choose a suitable location. Make sure that the area can accommodate the outlet without overloading the circuit. You'll also need to ensure that your project complies with building codes. Next, turn off the power to the circuit, then install and wire the outlet according to the manufacturer's instructions. Once the outlet is in place, test it. Lastly, be sure to use a cover that will protect it from moisture and other weather-related damage.

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.
