Master Seal Installers rank among the best I've ever known. I am a retired carpenter and former owner of a home improvement company. I personally replaced this window and the 14 others in my home 30+ years ago. Other replacement window bidders excluded protection/restoration of the beautiful interior finishes for this window (see picture) above our Kitchen sink where we spend a lot of time when we're indoors. I would estimate that the effort put forth to install this unit and leave the interior finishes intact exceeded 30% of the effort to install the other 14 windows that were included in the

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.

We interviewed a few companies before making the decision to go with Master Seal. The project involved replacing our sliding patio door and security door. The salespersons were both courteous and professional in their presentation. They got the job because they actually listened to what we needed, asked questions when unsure or wanted there to be no ambiguities between what was requested and how the contract was written. On top of that, they visited the site, measured, explained what was required to complete the project then listened to our questions, answered them expertly to seal the deal. Our

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.
