The humble door casing may be a small detail, yet it frames every room and instantly signals the quality of a residential build or remodel. Under-price it and you erode profit. Over-price it and you lose the bid. CountBricks created the door trim installation cost calculator to end the guesswork for busy contractors, remodelers, and DIY-savvy homeowners who demand precision without slowing the project timeline.
Built into our AI-driven estimating platform, the calculator turns real-time voice input into a complete material and labor breakdown—right from your phone or laptop. Simply say, “Ten solid-core doors, 3 ½-inch colonial casing, finger-joint pine,” and our engine instantly maps SKUs, local pricing, crew hours, and markup. The result is an itemized estimate ready to drop into your proposal or integrate into a CountBricks invoice.
1. Voice Capture: Speak or type project specs directly into CountBricks.
2. AI Parsing: Our algorithm recognizes door quantity, opening size, trim profile, finish level, and zip-code location.
3. Cost Engine: Live feeds pull lumber yard pricing, average wage data, and regional tax rates.
4. Instant Output: You receive square-footage math, linear-foot trim totals, waste factors, crew hours, and final cost per door—formatted for quick client approval.
• Trim Material: MDF, finger-joint pine, solid oak, or moisture-resistant PVC each carry different price tiers.
• Profile Complexity: Simple colonial casing installs faster than stacked craftsman or back-banded designs.
• Door Size & Quantity: More jamb height equals more linear feet; the tool scales labor accordingly.
• Finish Level: Raw, primed, or pre-finished dramatically changes prep time and paint costs.
• Regional Labor Rate: Dallas crews average \$52/hr, while Phoenix averages \$46/hr; CountBricks auto-adjusts.
• Site Conditions: Occupied remodel, new shell, or high-rise condo—voice tags add setup and protection time.
Using live data, CountBricks produces the following ballpark figures for a standard 2 6” x 6 8” interior door with 3 ½-inch finger-joint casing:
• Material: \$24 – \$31 per door
• Labor: \$38 – \$52 per door
• Waste & Fasteners: \$3 – \$5 per door
• Total Installed: \$65 – \$88 per door
Remember, these numbers update daily inside the calculator. A sudden spike in lumber or a seasonal labor shortage will show up before you submit your bid.
• Record voice notes at the jobsite; the calculator translates them into line items you can edit back at the office.
• Use project templates saved in your CountBricks.com/services dashboard to preload common casing profiles.
• Add custom overhead and profit percentages so every estimate already matches your business model.
• Generate sleek PDF quotes with a single click under CountBricks.com/portfolio branding—no extra design work.
• Link the estimate to a live schedule so accepted quotes automatically reserve crew hours.
Speed alone is not enough; accuracy wins. CountBricks combines both, delivering estimates in under a minute that stay within 2 % of final invoiced cost on average. Clients see transparency, you see higher close rates, and your crew sees a schedule free of costly surprises.
Is the calculator only for contractors?
Homeowners, builders, and designers also use it to validate bids and adjust budgets mid-design.
Can I change labor rates?
Yes. Override default wages or set company-wide rates in your settings.
Does it handle exterior door trim?
Absolutely—choose weather-resistant materials and exterior grade fasteners in the material dropdown.

When Maple Ridge Homes hired CountBricks to supply takeoffs for a 24-unit townhome build, door casing looked like a minor line item. Yet with 48 interior doors per building, small miscalculations would snowball fast. The superintendent used our door trim installation cost calculator directly from the job trailer.
