Cost to Support Beam / Header Replacement in Kansas City, MO (2026)

If you’re budgeting a support beam / header replacement in Kansas City, most projects run $1,479-$14,786, 1% below the $6,500 national average. What moves that number most is usually one thing: Beam Size and Span. On its own it can swing the cost by $500 - $15,000, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Use LVL instead of steel whenever span and load requirements allow - LVL is substantially cheaper to purchase and install than steel beams.

Material prices below are national averages; availability in Kansas City may shift costs slightly.

MaterialCost/UnitBest For
Dimensional Lumber (2x or 3-ply)$10-$20 per linear ft materials onlyShort window and door headers under 6 feet in non-critical applicationsLowest cost, widely available, easy to work with, no special equipment needed
LVL (Laminated Veneer Lumber)$25-$50 per linear ft materials onlyStandard window and door headers, floor beams, and most residential beam replacementsStronger than dimensional lumber, stable and consistent, handles longer spans, available in standard sizes
Glulam (Glued Laminated Timber)$30-$60 per linear ft materials onlyExposed beams in living spaces, long spans in open-concept designs, architectural applicationsExcellent strength-to-weight ratio, attractive natural wood appearance, available in very long spans
Steel I-Beam (W-Shape or Wide Flange)$50-$150 per linear ft materials onlyLong basement spans, load-bearing wall removal projects, or where headroom is very limitedMaximum strength for span, does not rot or warp, slim profile for long spans, permanent solution
Parallel Strand Lumber (PSL)$35-$65 per linear ft materials onlyColumn and post replacements, heavy point-load applicationsVery high density and strength, handles heavy point loads, consistent performance
