Engineered wood siding performs well on St. Louis homes built before 1940 in neighborhoods such as Soulard and Lafayette Square where brick foundations meet wood framing. The material expands and contracts with the city’s freeze-thaw cycles, so installers leave proper gaps at corners and use manufacturer-approved flashing at window heads to prevent water intrusion during frequent thunderstorms. Hot summers add UV exposure that can fade untreated surfaces, making pre-finished boards with UV inhibitors the practical choice for homes near Forest Park and Tower Grove South.
Older stock in The Hill and Benton Park often has uneven siding planes from decades of settling. Engineered wood installs over furring strips to create a flat plane and allow airflow behind the boards, reducing moisture trapped against sheathing during humid months. Crews check for lead paint on homes in Shaw and Forest Park Southeast before cutting, following local disposal rules that require sealed containment. Severe storm seasons also mean crews secure temporary tarps the same day when removing old siding to protect interiors from wind-driven rain.
Downtown and Midtown conversions from commercial to residential buildings require attention to parapet walls and differing roof lines. Engineered wood must terminate with metal Z-flashing and step flashing at these transitions to shed water away from the structure during heavy downpours. Crews also verify that new siding meets the Independent City’s energy code requirements for air sealing at penetrations before final inspection.
Nearby cities such as Clayton and Webster Groves have similar housing ages but different tree cover that increases shade and moisture retention. Installers adjust ventilation gaps accordingly when working on homes in University City and Kirkwood to keep the engineered wood stable through winter.
Technician insight
In St. Louis the thing that catches most people out with Engineered Wood Siding Installation is skipping the furring strips on older brick homes in Soulard and The Hill. Without that air gap, humidity and freeze-thaw cycles push moisture back into the sheathing during our long winters, and the boards start cupping within two seasons.
Lafayette Square Two-Story Replacement
Homeowner called after wind-driven rain entered through cracked cedar siding on the west wall. We found rotted sheathing behind the original boards and missing step flashing at the bay window. Installed new housewrap, furring, and engineered wood with upgraded flashing; the wall stayed dry through the next three storms.
