Window Company in Moraga, CA
Window and door work in Moraga comes down to one thing: the hills. Most homes here sit on sloped lots with older construction, wide window banks facing the ridge lines, and real exposure to afternoon sun from May through October. We’re Meridian Windows & Doors, part of the Garrison Partners family, and we approach every Moraga job with a written price before work begins and a 365-day guarantee that’s actually on paper. Whether it’s a single failed window on a 1960s ranch or a full patio door replacement on a view lot, call us at (817) 686-2228 and we’ll give you a straight answer.
Why Moraga Homes Are Different
Moraga’s housing stock runs from 1950s and 60s ranchers in Rheem Valley to larger 70s and 80s builds up toward Sanders Ranch, with newer construction mixed in along Camino Pablo. What they share is a common set of conditions: full sun exposure on south and west elevations, afternoon heat that pushes window seals hard, and canyon drainage patterns that can drive moisture into older frames. We see fog influence closer to the hills in the morning and dry heat by mid-afternoon, which is exactly the combination that causes wood frames to swell, vinyl to fade, and old aluminum single-pane units to sweat through the winter.
Sloped lots change the scope of the work, too. Many Moraga homes have raised foundations or partial basements, which means access to a window on the hill side can require staging on uneven ground. Patio doors, in particular, tend to sit on decks or hardscape built into the grade, and getting the threshold detail right matters because water runs downhill toward the house. None of this is exotic; it’s just Moraga. We plan for it before we ever write the estimate.
Our Main Moraga Services
Most Moraga homeowners call us for one of three things. Here’s how we handle each one in this area, with a local note worth knowing before you schedule.
Window Replacement in Moraga
Replacing a window in Moraga usually means matching the look of an older home while upgrading the glass to a low-E coating (a thin layer that reflects heat while letting light through). We remove the old unit, inspect the opening for hidden rot or settling, and set the new window to the existing framing, flashing the exterior to drain away from the house. On hillside lots, we pay particular attention to the sill and top flashing, because that’s where wind-driven rain finds its way in. Full details are on our Window Replacement in Moraga page.

Window Installation in Moraga
New-construction or addition work in Moraga requires dropping windows into fresh openings, usually while other trades are still on site. We coordinate with the framing schedule, set the units level and square, and make sure the rough openings meet code before the finish trim goes on. On Moraga’s sloped lots, we often have to account for elevation change across a single wall, which means more careful leveling than you’d need on a flat lot in the East Bay. See Window Installation in Moraga for the full scope.

Patio Door Installation in Moraga
Patio doors in Moraga take the most direct sun of any opening on the house, and many back out onto decks that sit above grade. We pull the old door, check the deck ledger and framing beneath the threshold, and install the new unit to drain properly. Sliding and swing doors both benefit from better seals and a threshold detail that keeps water moving away from the house, not into the framing. The complete breakdown is on our Patio Door Installation in Moraga page.
