"They arrived on time, it took about 2.5 hours, there is at least 18 inches or more of insulation, and I cannot wait to see the difference in the temperature in the house! Next weekend will be to do blown in insulation in the walls! Many thanks to owner Mike DePasquale and Energy Consultant Kevin Sweeney!"

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"
