Siding Problems We See Most in Woonsocket
Woonsocket housing is old and built close together. Three story multi family buildings carry enormous wall areas, and whatever siding is on them has usually been there for decades.
Under it there is often original wood clapboard, sometimes covered twice. Each added layer trapped a little more moisture against the sheathing, and the bottom courses are where it shows first.
Northern Rhode Island winters finish the job. Snow piles against the lower walls, melts, refreezes, and works into any joint that has lost its seal.
