Fiberglass or steel?
Fiberglass entry doors resist dents, won’t rust and handle Colorado’s sun and temperature swings well, and they can be stained to look like wood. Steel doors are strong and economical but can dent in hail. We’ll walk you through the trade-offs for your home and budget.
Why installation matters
A drafty or sticking door is almost always an installation problem: an out-of-square frame, missing flashing at the sill, or failed weatherstripping. We set the frame plumb and square, flash the sill pan so water can’t get under the threshold, insulate the gap, and seal and trim it properly.
