FLAT RATES! I charge a flat rate for standard entry door and storm door installation, so call for details. This case, however, was a bit extra due to the fact that the height of the rough opening was a full two inches different left to right! There was some major surgery and correction going on here. As always, MasterCraft steel doors carry an industry-leading lifetime warranty, Energy Star rating, high density foam core, and insulated glass. Good stuff…and toasty warm!
