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."

Generator Install questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

As long as your generator is used as recommended by the manufacturer, it’s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator’s placement and set-up meets safety standards when installing or repairing your back-up power source.
