“I received 11 new windows from Master Seal. They are absolutely beautiful. The installation went well and I am very pleased with this company. I also had a security door installed about a year ago and I love my door. Really makes me feel safe. I recommend Master Seal. Special shot out to Mr. Lambert and the office staff.”

“I finally got my beautiful new Master Seal door and I couldn’t be more pleased. It is beautiful and worth every penny. Our installer Ron Behr was friendly, professional and did an amazing job. Thank you Master Seal for making my home feel safe, secure and beautiful.”

“I had the builder grade garage entry door replaced by Master Seal. The price was well worth it. As they say, you get what you pay for. They recommended an AMI door with magnetic seals and the door is excellent! I love my new door and I can’t believe it took me so long to replace it! Ron Behr did the installation and he was fantastic – very professional and detailed to get the door just right. When my new sliders come in, Ron will be installing these too. I can’t wait! I highly recommend Master Seal.”
