"Everything was really good including scheduling except for one of the breaker handles got broken while testing and they didn’t replace it.  This made the new electrical panel look used.  I would be worried about touching this part of it if there was water in the basement. He made it easy for me to understand what they were going to do and communication was good with them."

"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

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

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.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.
