Natural stone vs. manufactured veneer

Natural stone veneer is quarried — variable thickness, real weight (12–15 lb/sq ft), and it weathers correctly with the climate, developing patina rather than degrading. Manufactured stone veneer is cast concrete with iron-oxide pigment; it's lighter (8–12 lb/sq ft, which matters on wood-framed walls), installs faster, and costs less ($15–$35/sq ft vs. $28–$55/sq ft for natural). The tradeoff shows up on a northern or western exposure in Rochester, where manufactured veneer begins face spalling at 12–15 years from freeze-thaw moisture cycling in the concrete matrix — a failure mode natural stone, installed correctly, doesn't have.

The installation sequence that prevents failure

Substrate assessment comes first — vapor barrier, lath, and a scratch coat rated for the wall type. Weep screed and flashing go in at the base before any stone is set; that detail is the exit path for the water that inevitably gets behind veneer in Monroe County rain and snowmelt, and skipping it is the single most common cause of veneer delamination found on inspection. Type S mortar suitable for exterior freeze-thaw goes up next, stone is selected and dry-laid on the ground for fit before mounting, and the finished joints are pointed and brushed — sealed only when the specific stone calls for it.

Older housing stock needs a different mortar

Pre-1930s Rochester homes with soft, hand-fired brick or historic sandstone need lime-based mortar for any veneer work that ties into the original masonry — portland mortar is harder than the historic material it's adjacent to, and that mismatch causes the older masonry to spall instead of the joint. A mortar-compatibility check on any pre-1930s home is standard practice before quoting veneer work that touches existing masonry. On newer construction — Henrietta and Victor's more recent developments, in particular — the substrate is usually plywood or OSB sheathing rather than block or brick, which changes the flashing and lath detail but not the underlying rule: the water management layer goes in before the stone, never after.
