Framing Estimating Guide
Structural framing estimating for new construction, additions, and remodeling projects.
Overview
Framing estimates are built from lumber takeoffs based on plans and specifications. Accurate framing bids require counting every stud, plate, header, joist, and rafter, then adding a waste factor. Labor is typically bid per square foot of floor area or per linear foot of wall. Engineered lumber (LVLs, TJIs, glulams) adds cost but is often required by the structural engineer for longer spans.
Common Projects
- →New construction wall and roof framing
- →Room addition framing
- →Basement or attic framing for finishing
- →Load-bearing wall removal with beam installation
- →Deck framing and construction
Pricing Factors
- ✓Total square footage of framed area
- ✓Wall height (8-foot vs. 9-foot vs. 10-foot)
- ✓Engineered lumber requirements (LVL, TJI, glulam)
- ✓Roof complexity (gable, hip, cut vs. truss)
- ✓Window and door header sizes and counts
- ✓Local lumber pricing (fluctuates significantly)
Materials List
- •Dimensional lumber (2x4, 2x6, 2x8, 2x10, 2x12)
- •Engineered lumber (LVL beams, I-joists, glulam)
- •Plywood and OSB sheathing
- •Roof trusses (if not stick-framed)
- •Simpson Strong-Tie connectors and hangers
- •Nails (16d sinkers, 10d, 8d) and screws
- •Construction adhesive
- •Metal strapping and hold-downs
Estimating Tips
- ★Do a detailed lumber takeoff from plans rather than estimating by square footage — it is more accurate and reduces waste.
- ★Track lumber prices weekly and include an escalation clause in contracts for projects starting more than 30 days out.
- ★Add 10-15% waste factor for lumber and 5% for sheathing to account for cuts, damaged boards, and layout adjustments.
- ★Price engineered lumber items separately — they have longer lead times and higher costs than dimensional lumber.

Common questions about framing estimating
Framing is commonly priced per square foot of floor area at $8-$16 per square foot for labor only, or $15-$30 per square foot for labor and materials. Complex designs with tall walls, many corners, and engineered components fall at the higher end. Some framers bid per linear foot of wall at $6-$12.
Lumber prices can swing 30-50% within a few months. Protect yourself by including a material escalation clause in contracts, quoting material validity for 7-14 days only, or purchasing and storing lumber early for confirmed projects. Always use current pricing, not historical averages.
Plan for 10-15% waste on dimensional lumber (studs, plates, joists) and 5-10% on sheathing. Complex layouts with many angles and short walls generate more waste. Engineered lumber waste is typically lower (3-5%) because pieces are cut to specific lengths.
