"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

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

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.

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home
