"I'd give zero stars if I could. Called to get a drip fixed and was told it'd be about a week out, which we decided we could live with. Since this is an active drip, we've been managing by using a bucket and turning the main water valve off when not needing to use water. ON THE DAY OF OUR SCHEDULED APPOINTMENT, they called and said unfortunately another job was running over and they needed to reschedule our service. I figured it'd be the next day or at most 2 days... Nope, they told me it'd be 10 more days before I could be fit in due to their other commercial jobs that they can't change. Had I known I'd be cancelled on day of I could have had a half dozen other plumbers come out. If they can't reliably serve residential customers, then they should be honest or don't schedule them. If you're looking for residential work, DON'T TRUST the scheduling department of this place."

"I couldn't be happier. From Mike the estimator, who first tried to locate the problem wiring but the wiring was about 60 to 70 years old. We knew it needed to be replaced. Mike was there about 2 to 3 hours and didn't charge us for that time. Our electricians, Kris and Adam were wonderful. Since I would have all ceiling boxes installed I was told I could have one in every room if I wanted. I had ceiling fans put up in the kitchen, dining room, living room and my daughters bedroom. All rooms but the other bedroom as no one stays in that room and I already had the light fixture. She got motion sensor closets that not only go on when the closet is opened, they are quite bright for her to see her clothes, which was a big problem for her in the past. The back hallway has always been an issue changing lightbulbs as it is a really high ceiling and very hard to change bulbs. They put in recessed lighting with LED lightbulbs that they say will last 50 years. They also put one of these recessed lighting in the kitchen in leu of the tulip light fixture that she had. They even fixed the outside lighting so when our dog goes out at night we can actually put a light on for him. (He is a black lab, very hard to see in the dark.) The whole job was completed in 4 days and they cleaned up great. I am very impressed and will definitely use them again."

FAQs for generator installation projects in Mequon, WI
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
