Building Envelope Trades
Exterior Wall Panel and Siding Estimating Services
Tribuild takes off cladding by system and elevation: panels by area with the subframing, flashing, trims, and sealants that make them watertight, so metal, composite, and fiber-cement systems are each priced as complete assemblies.
Cladding bids are priced on the panel and lost on everything behind it. Tribuild takes off wall panels and siding by system and elevation, panel area first, then the subframing, flashing, closures, and sealants that make the wall perform, so IMP, ACM, fiber-cement, and phenolic systems are each carried as complete assemblies.
Subframing and attachment are quantified behind every panel type, flashing and trim are carried by linear foot per detail, and every deliverable ships with an elevation-keyed workbook and documented assumptions your team can price and defend.

Frequently asked questions
Exterior elevations, wall sections and details, the panel/cladding specification, and any panel layout drawings. Details drive subframing, flashing, and closure scope beyond the panel face.
Yes, girts, hat channel, and rainscreen subframing behind the panels are quantified, since attachment drives a large share of the labor.
Each system (IMP, ACM, fiber-cement, phenolic) is quantified on its own by elevation and area, since they carry different material and labor.
Yes, perimeter, transition, and corner flashing, closures, and joint sealants are carried by linear foot per the details.
Yes, always. Color-coded PDFs and Excel workbooks are standard, and the native source files are included with every deliverable.
