"Could not be more happy. Everything just went as well as it could have during this crazy COVID stuff. Windows went smooth, roof in a day and siding was a few days. Entire project start to finish was 8 days and the clean up was exceptionally well done. Did not even know they were here. Definitely recommend Bradford Xteriors to anyone needing things done. Jason, the owner is very wired at all time but none the less a great guy and now friend."

"We have worked with Brad Holbert with Hunter Construction Co., on a number of home renovation projects from 2002-2012. During this time, we have been extremely satisfied with both cost and quality, as well as Brad's integrity.
Brad excels at project management and the orchestration ensuring that everything falls into place in a timely manner. Brad has incredible follow through and a great sense of urgency. He clearly understands a homeowners concerns and frustrations.
Working with Hunter Construction, we never have to worry about loose ends. In fact, we used Hunter Construction's services to help us when we needed a new roof. We could of found a roofing company on our own through friends, but we knew that if a problem arose over time, we could always call Brad, and he would take care of it. Having had a problem in the past with shady
workmanship and tradesman disappearing, engaging Hunter Construction Co., for this purpose gave us the added security of knowing we always had someone to call if a problem occurred after the work was completed. One of the greatest benefits of working with Hunter is Brad's temperament. Brad returns calls promptly and is always available. Brad is an excellent Handyman and is less than half the price of other handyman companies. We highly recommend Brad and his company, Hunter Construction Co.

Energy Efficiency Auditing FAQs, 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.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency. 

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.
