How to Bid Interior Door Installation Jobs for More Profit

Learn how to bid interior door installation jobs accurately. We cover per-unit pricing strategies, labor time, and tools for sending professional quotes.

The Per-Unit Pricing Strategy

Mastering how to bid interior door installation jobs starts with a 'per-hole' pricing model. Most contractors charge between $150 and $300 per door for pre-hung units, which accounts for hanging the door, installing the casing, and mounting the hardware.

Volume Discounts and Efficiency Rates

Efficiency is your best friend when bidding on multi-door projects. If a homeowner wants 10 doors replaced, you can often offer a small volume discount because your setup and cleanup time are spread across more units, making the total quote more attractive.

Accounting for Disposal and Teardown

Don't forget to charge for the removal and disposal of old doors. Whether it's $25 per door or a flat fee for a dumpster run, accounting for the labor of hauling heavy slabs out of the house is a crucial step in learning how to bid interior door installation jobs.

Specialty Door Upcharges

Standard interior doors are straightforward, but pocket doors, barn doors, or heavy solid-core types require significantly more labor. Ensure your estimate reflects the extra time needed for track leveling or structural wall modifications required for these specialty styles.
