After more than ten years working in exterior construction around Western Pennsylvania, I’ve learned that choosing a siding company in Pittsburgh, Pennsylvania has very little to do with brochures or color samples. The real test shows up months and years later, after wind-driven rain, winter freezes, and humid summers have all had their turn with the walls.
One of the first projects that changed how I evaluate siding work involved a home where the owners complained about cold drafts along an upstairs wall. The siding had been replaced not long before, and from the street it looked sharp. Once we removed a few panels, the problem was obvious. The house wrap had been cut short around a window opening, and flashing had been treated as optional. Moist air was getting behind the siding and freezing in winter, pulling heat right out of the room. The materials weren’t the issue—the installation decisions were.
I’ve found that Pittsburgh homes often hide their weaknesses until siding comes off. Last spring, we worked on a house where a small porch roof tied into the main wall at an odd angle. The previous crew had sided right over the transition without addressing drainage. Years of slow moisture had softened the sheathing underneath, something no one noticed because the exterior still looked fine. Catching it during the siding job kept the repair manageable instead of structural.
A mistake I see homeowners make is assuming siding is mostly cosmetic. In this climate, siding is part of the home’s water-control system. I’ve personally removed siding where starter strips were nailed too tight, seams weren’t taped, or panels were installed without room to expand and contract. Those shortcuts don’t show up right away. They show up as buckling during temperature swings, moldy smells indoors, or paint failure inside the house.
Experience also teaches you which ideas to push back on. I’m cautious about any siding company that rushes prep work or avoids talking about what might be uncovered once old materials are removed. Pittsburgh homes—especially older ones—often have rot near deck ledgers, window sills, or older additions. Addressing those issues during a siding project is inconvenient, but ignoring them guarantees bigger problems later.
The siding jobs that hold up here aren’t rushed and aren’t treated like surface upgrades. They’re done by companies that respect how moisture moves, how walls need to breathe, and how unpredictable Pittsburgh weather can be. When siding is installed with that mindset, it quietly does its job season after season, without demanding attention or repairs.
