Tools
The mistakes that cost DIYers the most, and how to stay ahead of them.
Skipping the sill pan and flashing, leading to rot
Not shimming plumb, so the door drags or gaps
Overspraying expanding foam, which bows the jamb
Leaving gaps uncaulked, which wastes energy
It depends on three things: your skill level, your time, and your tolerance for the riskiest parts of the project.
When DIY makes sense
When to hire
Doable with some project experience and comfort handling permits and inspections.

Materials
The single biggest material variable is your product choice. Steel entry door (budget, secure) and Fiberglass (durable, low maintenance) sit at opposite ends of the price spectrum, a decision that can shift your materials budget by 40–60%. Key line items include prehung exterior door, flashing tape and sill pan, exterior-grade caulk and spray foam, each priced per unit and sensitive to regional supply-chain conditions. Bulk purchasing and timing your order outside peak season (spring and early summer) can reduce material costs by 10–15%.
Labor
BLS occupational wage data shows exterior-trade crews earn $28–$52/hour depending on metro area, and most exterior door installation jobs require a two- to three-person crew for at least one full day. Labor typically accounts for 40–60% of the total project cost. Project complexity, custom details, tight access, or non-standard configurations, adds crew time and can push labor costs well above the national average.
Site conditions
Slope, soil type, and existing-structure condition are the three site factors contractors price most aggressively. Demolition or removal of old materials adds dumpster and disposal fees that rarely appear in online estimates. Local code requirements, permit fees, required inspections, and jurisdiction-specific material standards, can add $200–$1,500 to any project before a single tool is lifted.
