How this shows up in Hillcrest

The mesa climate is mild, but the housing is old. Most homes date to the 1910s through 1940s, built with lath-and-plaster walls, original wood windows and doors, and period trim and hardware that has to be matched rather than swapped for box-store parts. Decades of settling leave their own cracks and out-of-square openings.

The blocks off Fourth, Fifth, and Robinson hold older single-family stock where plaster patching and original-trim repair are typical, while the towers around Washington Street and University Avenue run drywall repair, interior-door realignment, and fixture swaps that need HOA coordination and elevator moves. Building access is the practical constraint in the mid-rise work.
