"If I could give this guy a zero rating I would. He came 2-19-20 to give us an estimate on our failing toilet and drippy faucet. He was coming yesterday, 2-21-20, to do the repair at 3:30pm. My husband took the afternoon off work to be home. At 3:40pm he still was not here, so I called him. He told me I should **get someone else**. He comes across as a **good old boy** and will talk your leg off. Even about other customers. He drives a retired vehicle and I would think would have ample room to stock normal plumbing repair parts such as a toilet fill valve one would think. Unreliable. Move on from him is my opinion. My husband was so mad he watched online videos, and did the necessary repairs for $20."

I am a locally owned and operated company that takes great pride my work. I specialize in bathroom remodels but have many years of experience doing electrical and plumbing work as well. I pride myself on the quality of my work and well as my commitment to outstanding results. I look forward to speaking with you about your remodeling needs and building lasting relationships with my clients.

"I hired Todd to reconstruct a medium sized, dilapidated workshop structure on my property to be used as a candle making studio. I had confidence the building could be improved upon but was not exactly sure what to expect. The tin roof was caving in, the building had fire damage, and it was structurally "askew." Todd started with the the side of the structure with the most damage. The results, thus far, are amazing. The side he is working on looks nearly brand new. I am not only impressed with his attention to detail and craftsmanship but also his willingness to articulate his ideas, processes, and techniques. Finally, his time management is outstanding. I have worked with other craftsman in the past and although they might have done great work, showing up on time wasn't always the biggest priority. I highly recommend Todd for any handyman+ job and more! :)"

"Thomas came to review some work we needed done. He not only reviewed but also accomplished it. He found the problem with our shower leak and fixed it on the spot. I had electrical problems with a few of my outlets. He found the problem to be in the wiring. He got them re-wired and replaced the outlets. He also fixed a false ceiling we have in the basement by fixing the structure and replaced the broken panels. Can't say enough about all this work getting accomplished in a short period of time and like his Marine Corps background, he left all the places he repaired spotless. Thanks Thomos and see you next time we need a true handyman."

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
