Replacing or adding a patio door seems simple—until you try to pin down the cost. Labor rates vary, material prices move daily, and every opening hides unique framing surprises. At CountBricks, we cut through the guesswork. Our AI-driven estimating platform captures live material costs, local labor rates, and project-specific tasks in real time. The result: reliable numbers you can bank on before the first stud is removed.
Search online and you will see ranges from $800 to $6,000 for patio door installation. Those figures are so broad they are practically useless. CountBricks replaces national averages with:
• Geo-specific labor rates pulled from our contractor network
• Live material feeds from regional suppliers
• AI analysis of door type, wall construction, trim, finish, and disposal requirements
• Automatic inclusion of permit fees and inspection schedules where required
1. Door style: French, sliding, multi-slide, or bi-fold each has different unit costs and installation complexity
2. Frame material: Vinyl, fiberglass, aluminum-clad wood, and solid wood affect both price and longevity
3. Opening modification: Widening or creating a new opening requires structural headers, sheathing, and exterior finish work
4. Glazing options: Low-E, triple pane, and integral blinds can add 15-35 % to material cost
5. Interior and exterior trim details: Paint-grade versus stain-grade millwork, siding patching, and stucco repairs shift the budget
6. Site access and protection: Upper-level decks, tight side yards, or extensive landscaping increase labor hours
Our workflow streamlines the entire process—from the first homeowner call to the final invoice.
1. Voice Capture: A contractor walks the site with our mobile app. CountBricks listens and transcribes the conversation about dimensions, obstacles, and client preferences.
2. AI Takeoff: Photographs or PDFs of the existing wall or blueprint are uploaded. CountBricks auto-detects dimensions, framing layout, and siding type.
3. Task Generation: The system builds a task list—demo, header install, door set, flashing, insulation, trim, paint, and haul-off.
4. Real-Time Pricing: Material SKUs are matched to local supplier feeds; labor hours align with local wage databases.
5. Instant Proposal: A branded PDF and web link are created, including line-item pricing, scope notes, and timeline.
6. One-Click Invoice: Upon approval, tasks convert to an invoice schedule with progress billing.
• Standard 5-ft vinyl sliding door, existing opening, ground floor: $1,450 – $2,200
• 6-ft fiberglass French door, minor framing adjustment: $2,800 – $3,600
• 12-ft multi-slide aluminum-clad wood door, structural header upgrade: $8,500 – $12,000
These numbers include labor, materials, trim, flashing, and disposal—no hidden allowances. Because CountBricks pulls prices at the moment of estimate creation, you avoid the 10 %+ contingencies contractors add when guessing.
Structural Engineering – Enlarging an opening may require stamped calculations for the new header. CountBricks prompts for engineering based on span and roof load.
Permit Fees – Many municipalities treat door replacement as an energy upgrade. CountBricks integrates local permit fee tables so you see the exact amount.
Moisture Remediation – Discovering rot around an old door can add framing and insulation work. Our platform suggests contingency lines so surprises do not derail the budget.
• Measure the rough opening, not the slab size, to avoid expensive reorder delays
• Request factory-applied jamb extensions if wall thickness exceeds 4-9/16"
• Upgrade to stainless steel fasteners in coastal or high-humidity markets
• Order extra interior casing—matching profiles years later is nearly impossible
• Schedule painting or staining within 48 hours of installation to maintain warranty coverage
Live Pricing Locks – Material quotes are time-stamped, allowing homeowners to approve before prices fluctuate.
Accurate Labor Allocation – By matching tasks to historical productivity data, we prevent over- or under-bidding.
Integrated Scheduling – When the estimate is approved, CountBricks automatically populates a Gantt chart, reducing idle crew time.
Fewer Change Orders – Because scope details are line-itemed, misunderstandings drop dramatically.

The cost to install a patio door depends on much more than the sticker price of the door itself. By using CountBricks’ AI-powered estimation tools, you gain accurate, up-to-the-minute pricing, detailed scopes, and professional invoices—without hours hunched over spreadsheets. The result: profitable jobs, delighted homeowners, and zero pricing surprises.
A recent CountBricks client in Minneapolis wanted to replace a dated 8-ft sliding glass door with a 12-ft multi-slide unit to open the kitchen to a new deck.
Initial Challenge – The framed opening needed to grow by 4 ft, calling for a new LVL header, exterior siding patch, and interior re-trim. Local contractors quoted anywhere between $9,000 and $15,000, leaving the homeowner confused.

• AI takeoff measured existing framing from blueprint PDFs and flagged the need for a double 1-3/4" × 14" LVL header
• Real-time pricing locked material at $5,870, avoiding a supplier increase that hit two weeks later
• Labor hours calibrated to Minneapolis wage data, producing a labor subtotal within 3 % of final
• Permit fee of $246 auto-inserted, eliminating a surprise bill
Outcome – Final project cost landed at $11,980, within 1.7 % of the original CountBricks estimate. The homeowner approved the scope in 24 hours thanks to the detailed line items and Gantt chart schedule. No change orders were issued.
