We are new to Angie’s but are experienced with anything insulation related! Home Shield Insulation is proud to bring the benefits of energy efficiency, comfort, and improved air quality to home owners in the Charlotte metro area.

"Poor communication around the amount of dust that the installation would leave or that we would need to remove any belongings from the attic or most importantly the adjoining closet where my wife stored her wedding dress. The install crew was also careless, leaving very noticeable scratches and dings on window and door frames. Management promised to address these repairs and dry clean the wedding dress but gave us the run around for months without addressing any of the issues caused by their crew. What’s arguably worse is we haven’t seen anything close to the amount of savings on energy bills that was promised in our first summer with our new insulation."

Launch Energy specializes in conducting thermal imaging inspections of homes and buildings & performing mold & allergen test services. A thermal imaging inspection can indicate areas of energy losses in a home or building that result in higher utility costs, potential moisture and water damage conditions leading to mold growth, faulty electrical components, and thermal anomalies that can indicate the presence of pests. Every inspection comes with a detailed report of findings. We are a local small business that is professional, responsive, and flexible to your needs.

"Launch Thermal provided an excellent thermal imaging survey of my new construction home. Launch Thermal provided a clear list of requirements for an effective survey and worked to schedule a time that would provide the best results. The technician arrived on time, provided an overview of the process and the equipment in use, and explained every step and answered every question. I understood the type of deficiencies that could be identified as well as their causes and severity. Prior to leaving, Launch Thermal discussed potential problems with the house with me, and specified some that required additional research (for example, verifying that temperatures were within bounds for a specific component). I received a complete and professional report that included this additional research, background information, and other information that allows for a productive discussion with the builder to correct them. I was overall very pleased with the service."

Energy Efficiency Auditing questions, answered by experts

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

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

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Yes, advising on models that save electricity and reduce utility bills.
