Home Shield Insulation
Home Shield Insulation
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."
