"Robert Moore was very knowledgeable and experienced when he did the home assessment. He knew exactly what our attic needed. Then when the crew arrived a week later to do the job they were fast and efficient. Best part was they were very neat and organized when they were performing the work. Would recommend Arc insulation to all my friends and family."

"Greg, the owner, came out on two occasions to discuss the crawl space and drain tile. He is extremely knowledgeable and experienced in the crawl space industry. We had a few options and he told me about the new spray product he was using. It is this unique seamless liner that is sprayed on after preparing and insulating the area.
His crew was very professional and easy to talk to. We had some scheduling conflicts that were easy to work around and get the job done when we needed it to be finished.
The difference we noticed in the smell in our basement, the effect the insulation and seamless lining had on the air conditioning in our family room (which is above the crawl space) was immediate. We feel cooler air coming through the duct work since it isn't losing energy traveling through a non insulated space anymore and they basement smells and feels normal since the dirt and concrete is now completely covered by the new liner.
That new product is great.
Greg's company also did drain tile work in our basement. It was a different crew than the group who did the crawl space, but they were equally as professional and easy to work with. Rather than break up the job into 3-4 days they stayed late the first day to get everything ready and prepared so they could complete the job quicker. The job was done the next day. The price was very fair and the crew was extremely clean throughout thew whole process.
We now have a water tight, well insulated basement and we couldn't be happier with the results.
I have told several friends about the experience and would recommend them anytime. From Greg down to each of his crew members they really know how to do a good job and work with the customer."

Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.
