"We are pleased to recommend Triangle Reconstruction with our highest praise. It seems too simple to say that they do what they said they’d do, but that’s exactly what happened. Our home is around 50 years old. Ours was a large job - around a month and $30,000. We had Triangle Reconstruction come in after another moisture company provided mold remediation and a humidifier. I wish we’d contacted TR to start with. We provided TR with a structural engineering report. They created a plan to exactly meet all of engineer’s concerns. TR used temporary supports and replaced seal plates, girders, and joists for over half of our home. In addition, they poured footers and built new columns. They also added a few additional girders to firm up our floors. They removed and replaced our insulation. They sealed our porch and crawl space, replaced our vapor barrier, and installed a moisture meter. They wrapped our electrical cords and hung them. The people at TR are remarkable. A+++++"

"After my initial phone call, he was able to visit the job site the next day and provided me with a printed estimate detailing each job and how much labor and materials would cost within two business days. Very knowledgeable, I had several random projects covering all kinds of exterior and interior work and he was able to complete them all. Very friendly and easy to get along with, was pleased with his quality of work. We will be using him again for future projects."

"Good, PSNC came to inspect their work and several areas had to have more re-insulation added that was missed on the day of work. Emerald returned on a Sat. to complete this work and the paperwork completed so that I got an energy rebate from PSNC."

Energy Efficiency Auditing FAQs, answered by experts

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

Provide utility bills and clear access to all areas of the home, including the attic and basement.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

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.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours.
