What door projects cover
Door projects in the Denver metro include replacing interior or exterior doors, upgrading hardware, and sometimes creating or resizing openings. Exterior work adds weatherstripping, thresholds, and flashing details. A municipally licensed Denver general contractor coordinates door packages and related framing trades when openings change. Cost is project-specific and depends on door type, count, and whether rough openings change.
text
Fit and performance
Swing clearance, stack height, and flooring transitions affect fit. Exterior doors should address weather and security needs for Front Range exposure.
text
Permits and who coordinates the work
Like-for-like door replacements often do not need a City and County of Denver building permit. Changing opening size or adding new exterior openings typically does. Landmark Preservation may review exterior changes on designated properties when permits are required. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades when needed.
text
What buyers should prepare
Door count, interior vs exterior, swing direction, and whether openings will change.
FAQ
Common questions
Do door replacements need a Denver permit?
Often no for same-size replacements. New or resized openings typically need CPD building permits.
Who handles door permits and licensing?
A municipally licensed Denver general contractor coordinates the project and related specialty trades. Colorado has no statewide general contractor license.
Can exterior doors be replaced on a historic home?
Possibly, but Landmark rules may apply on designated properties. Check before ordering.
What about fire-rated doors?
Certain locations require rated doors and hardware. Confirm use and wall type on site.
What information helps define scope?
Door locations, interior vs exterior, opening changes, photos, and city or county.
