"Shaun and his guys worked at my house for over a 6 month time period due to a large leak that caused my 2 bathrooms, kitchen and basement to be ripped out. Throughout the entire process he made sure to show up with his guys and walk both my husband and I through what we wanted done and how they were going to do the work. All of the guys that he had work for him were respectful and cleaned up after themselves. They were always on time and also they were very good with my German Shepard puppy who it was not always to keep in contained areas. Throughout the project we kept adding more things on and the whole team was absolutely amazing and always doubled checked with us for all the changes we would make and make sure it was to our satisfaction. I would highly highly recommend this company to anyone and everyone. If you want someone that will answer the phone and be there when things are rough this is the company for you! I don't know what we would have done without Shauns guidance and help throughout this entire process."

"I was overcharged for replacing a shower faucet cartridge. The plumber inspected the leak and ask me to sign a quote for $600 - which he said would cover the labor for the removal of the old cartridge. He said he needs to melt it out with a torch and may take an hour or two to remove the old one. The $600 covers all labor and parts. I signed the quote. He open up the shower, removed the leaking cartridge and replace with a new one in 15 minutes. He stayed in the bathroom answering emails for 10 minutes because he was embarrassed - and when I confronted him - he said it came out easily - but still charged me $600 since I already signed the service agreement."

Generator installations FAQs
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 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.
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
