Header / beam span calculator

Real LVL 1.9E-2600Fb structural math — bending, deflection, and shear checked against span tables, the same way we size the header before a load-bearing wall comes down.

Budgetary sizing tool for planning conversations — final header sizing must be stamped by a licensed structural engineer for permit.

Scenario Span Tributary Load case Header spec
Kitchen island wall removal 14 ft 12 ft Floor only 1-ply 18" LVL
Open-concept living room header 16 ft 16 ft Roof + floor (multi-story bearing) 3-ply 18" LVL

Room-to-materials estimator

Trade-standard coverage rates — the same numbers our crews order from, including the waste factors most online calculators skip.

From clients

“They showed us the actual beam calculation before we signed off on removing the wall — nobody else even offered.”

— Sarah, Open-Concept Conversion, Wellesley

“The schedule they gave us at contract signing was within four days of the actual finish date. That never happens.”

— Marcus, Whole-Home Renovation, Weston

“Our kitchen island was the whole reason we hired them — they engineered the header instead of just telling us it would work.”

— Priya, Kitchen Remodel, Newton

“Basement had a moisture problem two other contractors wanted to finish right over. Cornice fixed it first.”

— Daniel, Basement Finishing, Needham
