Looking for windows in Glenshaw? Ireland Contracting is a Pittsburgh window company installing replacement windows across Pittsburgh and Western PA: Pella wood-clad, Marvin wood, Andersen 100 Series and A-Series, and ProVia vinyl units, measured to your openings and installed by our own crews rather than a subcontractor. From replacing a single leaking window to new windows for the whole house, the result is a draft-free fit, clean trim inside and out, and lower heating bills through a Pittsburgh winter.
Glenshaw is home base for Ireland Contracting. Our headquarters is right on William Flinn Highway. Shaler Township homeowners have trusted us with their roofs, siding, and gutters for decades, and being local means we respond fast when storms roll through.
Glenshaw's established housing stock often still has original single-pane or early replacement windows that leak heat every winter. Swapping them for modern double-pane, low-E units noticeably cuts drafts and the heating bills that come with older North Hills homes.
Most of the windows we replace are original to the house: rope-and-pulley wood sashes in Mt. Lebanon, Bellevue, and Squirrel Hill, or first-generation vinyl from the 1990s that has fogged between the panes. Either way, the symptoms are the same: drafts you can feel from the couch, condensation on the inside glass, sashes that won't stay up, and a furnace that runs all night. A modern double- or triple-pane window with low-E glass and an argon fill fixes all of it at once.
We install four brands so the frame material matches the house and the budget. ProVia vinyl is the value choice for most homes: low-maintenance, well insulated, and backed by a lifetime transferable warranty. As an Andersen Certified Contractor we install the Andersen 100 Series, built from Fibrex composite, a step up from vinyl that comes in dark colors, and the A-Series, with a solid wood interior and a weather-resistant exterior. Pella wood-clad windows give you real wood inside with an aluminum exterior that never needs painting, which suits the region's brick and stone homes. Marvin wood windows are for historic and custom work where the profile and the species matter. We'll show you the options side by side and tell you which we'd put in your house.
Full-frame or insert? An insert (pocket) replacement keeps your existing frame and trim and is the faster, less expensive route when the old frame is sound. A full-frame replacement removes everything down to the rough opening so we can inspect and reflash the sill, the right call when there's rot, water staining, or you want to change the window size. We check the frames on the measure visit and recommend one or the other, not both.
One thing we don't do: window repair. We don't replace glass, reglaze sashes, or fix balances on existing units. If a window has failed, we replace the whole unit properly rather than patching it, and we'll tell you honestly if it's only one or two windows that need it.
