Prices for exterior gypsum sheathing vary by thickness, moisture resistance, and installation scope. The cost includes materials, labor, and handling to cover a typical 4×8 sheet project. This article addresses the price and factors buyers should consider for exterior gypsum sheathing needs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material (4×8 sheet, 1/2″ to 5/8″ thickness) | $12 | $25 | $40 | Standard moisture-resistant gypsum board |
| Labor to install per sheet | $40 | $70 | $110 | Basic masons/finishers; weather dependent |
| Delivery/haul-away | $4 | $8 | $15 | Distance-based |
| Permits or inspections | $0 | $60 | $200 | Local requirements vary |
| Waste disposal/cleanup | $5 | $10 | $25 | Debris from cutting and fasteners |
Price Range By Sheet Size And Grade
Typical exterior gypsum sheathing prices start near $12 per 4×8 sheet for basic 1/2″ boards and rise to about $40 per sheet for higher-grade moisture-resistant boards with enhanced fiberglass facers. Installed per-sheet costs commonly run $60 to $160 depending on regional labor rates and access. For budgeting, assume 10–12 sheets per 1000 sq ft of wall area, plus fasteners and tape. Assumptions: Midwestern labor rates, standard access, normal weather.
Major Cost Components In A Gypsum Sheathing Quote
The quote splits into key parts that buyers can compare easily. Material cost, installation labor, and delivery/cleanup dominate the total. A typical table below shows how these add up per 1,000 sq ft of wall coverage.
| Cost Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (4×8 sheets, 1/2″–5/8″) | $120 | $260 | $520 | Depending on moisture resistance |
| Labor (installation) | $400 | $840 | $1,200 | Crew size and access impact |
| Delivery/Disposal | $40 | $90 | $180 | Distance-based |
| Sealing/Finish tape | $20 | $60 | $120 | Joint treatment included |
| Permits/Inspections | $0 | $50 | $150 | Region-dependent |
| Warranty/Overhead | $10 | $40 | $80 | Estimate |
Mini-formula:
Variables That Drive The Final Exterior Gypsum Price
Project scope and site specifics push the total up or down. The strongest drivers include wall area, board thickness, and environmental conditions. Region and crew size directly affect hourly rates, while delivery distance changes transportation costs. A moderate 1,000 sq ft project can vary widely if moisture-resistant boards are chosen or if weather delays labor time.
Concrete Details That Can Shift The Quote By Region
Regional price differences reflect demand and labor markets. In coastal markets, moisture-control features may add to material costs, while inland areas with competitive crews can yield lower installed prices. For a 1,200 sq ft exterior, expect a regional delta of roughly ±25% between high-cost coastal cities and lower-cost inland zones. Assumptions: Typical local wage scales; standard building codes.
How To Cut Exterior Gypsum Sheathing Costs Without Cutting Quality
Scope controls and material choices are the main levers. Choose standard 1/2″ boards, limit back-cutting waste, and batch deliveries to reduce costs. Scheduling installations in dry months minimizes weather-related delays. When possible, bundle purchase and installation with other exterior finishes to gain a small discount.
Alternatives To Exterior Gypsum Sheathing And Their Price Impacts
Options like fiber cement boards or OSB with different weather barriers may change total cost. A fiber cement alternative typically ranges higher per square foot than gypsum, but may offer longer life in harsh climates. For a 1,000 sq ft project, a fiber cement setup might run $2.50–$4.50 per sq ft including labor, compared to gypsum’s $1.50–$3.50 per sq ft installed range. Assumptions: Similar wall area, standard substrates, average access.
Typical Project Scopes And Corresponding Installed Ranges
A straightforward exterior gypsum job often covers weather barrier prep, sheathing installation, tape, and primer-ready joints. For 800–1,200 sq ft, installed costs commonly fall in the $1,200–$3,000 range for materials and labor combined, depending on board type and accessibility. Smaller jobs tend toward lower per-square-foot costs, while larger, multi-wall projects gain modest bulk savings.
Practical Quotes: What To Ask And Expect
When reviewing quotes, verify per-sheet pricing, installed price per square foot, and whether delivery/cleanup is included. A typical buyer should expect a four-step breakdown: materials, labor, delivery/cleanup, and permits. Always request a per-square-foot installed rate as a cross-check against a per-sheet quote.
Note on Units
Prices use U.S. units. Per-square-foot comparisons help when walls vary in height, while per-sheet pricing clarifies material needs. For a 1,000 sq ft wall area, expect roughly 135–170 sheets if using standard 4×8 boards, depending on waste and window/door openings.
Final tip: Always confirm compatibility with the selected weather barrier and finishing system for a complete exterior assembly.
