The company is co-owned by Rusty Holt and Chris Cochran. Together we bring to the construction and decision process over 40 years of hands on building and business experience. We have worked for the some of the nation’s largest contractors as a superintendent/PM and acted as the project manager and owner’s representative for multimillion-dollar medical complexes. These are just two of the roles we have filled in the industry. In addition, we have met the needs of many individual homeowners. We are each familiar with what it takes to complete a given division of construction at the tradesman level. Our experience over the years has focused on multi-family, single family residential, hospitality, medical offices, light industrial, and, general retail. Projects have included ground up and interior upfits. People ask us, what is your niche. It’s simple, we build. One of the reasons we are successful is our dependable base of sub-contractors can be counted on to show up and do quality work at a competitive price. Recently our company was featured in Mount Pleasant magazine. You can view the article at : http://mountpleasantmagazine.com/2019/people/citadels-quarters-one/

"So pleased with my choice to use Blue Horizon, Rusty was great to work with, he kept me well informed on the schedule work. His crew showed up on time and completed the work that was scheduled for that day. I used most of Rusty suggestions , from the design firm to the cabinet maker. Rusty taught me a lot through this 8 month process of the remodel. When an issue came up( as they often do in a remodel), he always had options to handle the situation. We are very pleased with our “new” house. I don’t think you will find a better company or person to work with. Ask for Rusty."

The owner, Brian, is tremendously knowledgeable and his employees are well trained, very polite and professional, and provide excellent service. Sam, the last electrician from C & B Electrical who came to replace our ceiling fan, did a superior job with what could have been a tough job: installing a ceiling fan in a pine-panelled ceiling and getting it to look like it was the perfect match and always there! We were very impressed with his skill and he was exceptionally nice, as well. We are very glad we found this company on Angi's List 2 years ago and have used them ever since."

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
