Buyers commonly see cost estimates for a 20-foot glulam beam based on grade, species, end details, and installation requirements. The main cost drivers are material grade, beam size, finishing, and labor. This article gives practical pricing in USD with clear low–average–high ranges.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Beam price (material) | $500 | $850 | $1,600 | 20 ft, standard grade glulam |
| Delivery | $50 | $150 | $300 | Within 50 miles |
| Installation / labor | $300 | $600 | $1,000 | Includes crane or rigging |
| Permits & inspections | $0 | $100 | $300 | Local requirements vary |
| End treatments / finishing | $0 | $50 | $150 | Wax, sealant, or edges |
| Contingency | $0 | $50 | $200 | Estimate margin |
Assumptions: region, specs, labor hours.
Overview Of Costs
Cost range for a 20-foot glulam beam typically spans roughly $500–$1,600 for the beam itself, with total project costs often between $1,000 and $2,600 once delivery, labor, permits, and extras are included. The exact total depends on species, grade, end configurations, support conditions, and whether off-site fabrication or on-site cutting is needed. Per-foot pricing commonly falls in the $25–$80 range, depending on quality and supplier.
Cost Breakdown
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty | Taxes |
|---|---|---|---|---|---|---|
| $500–$1,600 | $300–$1,000 | $0–$100 | $0–$300 | $50–$300 | Included or optional | Dependent on state |

Note: End treatments or custom profiles can add $0–$150 per beam, and stacking or multiple beams increases costs proportionally.
What Drives Price
Material grade and species are primary drivers. Higher-grade glulam or exotic species push price up to the top end of the range. Beam length and cross-section (depth) also affect cost, as larger beams require more wood and heavier handling. Finishing, coatings, and end treatments add modest costs but improve durability. Locally required permits can add time and fees, influencing total price.
Ways To Save
Shop around and compare quotes from wood fabricators or distributors who offer in-house fabrication and on-site installation. Consider pre-fabricated options or standard profiles to minimize customization. If possible, align beam installation with other work to reduce crane time and mobilization fees. In some markets, off-peak delivery or off-season scheduling can yield savings.
Regional Price Differences
Regionally, price deltas can be ±10–25% due to transportation, labor, and supplier competition. For example, urban areas may see higher delivery fees but faster lead times, while rural regions may incur longer transport but lower labor rates. Northeast and West Coast markets often quote higher baseline prices for premium services versus the Midwest or South.
Labor, Hours & Rates
Labor charges typically reflect crew size and duration. A single installation crew may take 4–10 hours for a 20-foot beam, depending on access and support structure. Typical residential or light commercial projects may budget $300–$1,000 for labor. data-formula=”hours × rate”> Higher complexity or crane requirements increase both time and cost.
Real-World Pricing Examples
Scenario A — Basic: 20 ft glulam beam, standard grade, delivery within 50 miles, no end customization. Beam $500, delivery $100, labor $300, permits $0. Total ≈ $900.
Scenario B — Mid-Range: 20 ft beam, higher grade, simple end cuts, crane delivery, moderate site access. Beam $1,000, delivery $200, labor $650, permits $100. Total ≈ $1,950.
Scenario C — Premium: 20 ft beam with special profile, moisture-treated finish, on-site cutting, extended delivery, and permitting. Beam $1,600, delivery $300, labor $900, permits $300, finishing $150. Total ≈ $3,250.
