Why Barrett & Sons Construction Is Moraga’s Preferred Windows & Doors Company

We’re not a franchise sending strangers in wrapped vans. Barrett & Sons Construction was founded in 1998, and Tom Barrett and his sons are on-site most days in Lamorinda. That’s why homeowners in the 94556, 94570, and 94575 zip codes keep our number handy when a window seal fails or a sliding door won’t slide. If something isn’t right, you call one number and Tom answers. That’s worth something in a town like Moraga.

Crew members arrive background-checked and uniformed. Every scope, every allowance, and every price change gets reduced to a written change order before work happens. That means no end-of-job bill that surprises you. Our name is on the truck, and the license number is published. It’s the same standard we bring to every Windows & Doors job in Moraga, from replacement patio sliders to custom window packages on those hillside builds above St. Mary’s College.

Our Windows & Doors Services in Moraga

Window Installation

Those 1960s and 1970s ranch homes that make up much of Moraga’s housing stock often still carry their original single-pane windows. In this microclimate, that means rooms get brutal heat loads on south and west exposures in summer, and cold drafts in winter. We install Andersen and Marvin windows, including dual-pane and low-E options, sized for the original framing or retrofitted into new openings. Permit-ready plans, no surprises.

Door Installation

Front doors, back doors, and especially exterior doors that swing onto windy hillside exposures. Moraga’s thermal range, from freezing nights to triple-digit afternoons, accelerates warping in cheap hollow doors. We replace them with solid, properly flashed and sealed units. If you’re on a hillside lot where yard drainage drives water toward the door threshold, we account for that before we ever cut an opening.

Window Replacement

Window replacement cost in Moraga runs $4,500 to $15,000 for a typical 8-to-12 window home. Older post-and-pier ranch homes in the flats off Moraga Road often have settled slightly, which means existing windows aren’t square. We frequently see this exact condition in pre-1980 homes. A quality replacement job here requires shimming, adjusting reveals, and sometimes rebuilding the rough opening. We handle it the same way every time: in writing, with real numbers, before we start.

Impact Windows & Doors

Moraga sits inside a State-designated Very High Fire Hazard Severity Zone. That brings Chapter 7A WUI building code requirements into play for exterior construction. Impact-rated windows with multi-pane glazing and ember-resistant assemblies aren’t a suggestion here; on some Home Additions & ADU in Moraga, they’re the law. We install impact windows and doors that comply with fire-rated glazing and structural requirements while still looking like a normal quality window from the inside. Expect impact window installation for a full Moraga home to run $8,000-$25,000.

Trusted Brands We Service in Moraga

We carry brands you can look up. On windows, that’s Andersen and Marvin. On doors, quality lines that hold up to valley heat and East Bay clay-derived shifting. On adjacent work, we use GAF roofing products when a window job turns into a roof flashing repair, and Schluter waterproofing systems when a door replacement connects to a tile entry. We also handle Fence Installation in Moraga if you’re replacing an old fence line during your exterior upgrade, and our crew does Driveway & Pavers in Moraga when a new front door deserves a better approach. We stock local parts and common weatherstripping profiles so a fix doesn’t mean waiting on a special order from out of state.

Common Windows & Doors Problems We See in Moraga Homes

• Fogged or failed double-pane seals. Moraga’s extreme temperature swings press seals hard. Once moisture gets between panes, the only real fix is replacement of the sash or the whole unit.
• Sticking or binding doors in hillside homes. Expansive clay soil under Moraga moves more than people expect. Doors that once swung free start catching. The right fix addresses the frame, the jamb alignment, and sometimes the threshold, not just the hinges.
• Dry-rotted wooden sills and casings. Winter rain hits the hills off Bollinger Canyon and Campolindo, then summer heat bakes the wood. The combination cracks paint and wicks moisture into the rough opening.
• Old aluminum single-pane windows in 1960s tract homes. Common throughout the neighborhood between Moraga Road and Camino Pablo. They transfer heat fast, and replacement is the single highest-impact improvement most owners make for year-round comfort.
