"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"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 FAQs, answered by experts

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

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.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.
