Adding a bay window instantly elevates curb appeal, delivers panoramic daylight, and creates an inviting nook inside your home. But what does it really cost to add bay window features to a residential property? At CountBricks, our AI-driven estimating engine breaks down every variable—materials, labor, permits, and finishing touches—before a single nail is driven. The result is a crystal-clear budget and timeline you can trust.
• Window style and dimensions: A 4-foot projection costs less than a dramatic 6-foot box bay. Our database automatically adjusts prices in real time.
• Framing requirements: Load-bearing walls, roof overhang modifications, or engineered headers increase structural labor.
• Glazing performance: Dual-pane vinyl sits at the entry price point, while triple-pane fiberglass with low-E coatings can raise material costs 30 %-40 %.
• Exterior finish: Matching stucco, fiber-cement, or brick veneer dictates additional trades and lead times.
• Interior trim and bench seating: Built-in storage benches, crown molding, and paint upgrades add custom aesthetic value—and cost.
Our Fresno clients typically see the cost to add bay window fall between $4,500 and $9,800 for a standard 5-foot projection. High-performance models with custom millwork can exceed $14,000. CountBricks pulls live pricing from regional supplier APIs, so you see today’s numbers, not last quarter’s averages.

CountBricks is more than an estimating app; it is a complete pre-construction ecosystem purpose-built for residential contractors and homeowners.
Simply discuss your project on the jobsite. Our AI listens, populates materials, tasks, and local labor rates, and generates an itemized proposal in minutes—no spreadsheets required.
• Live supplier integrations ensure your quote reflects today’s lumber, glazing, and trim costs.
• Automatic alerts flag sudden cost swings so you can lock in prices or pivot quickly.
Upload PDFs, and CountBricks AI identifies existing wall loads, header spans, and rough-opening dimensions. That accuracy prevents costly change orders once construction begins.
Within the same interface you can brand, print, or email professional proposals straight to clients. Every line item is traceable back to the original data source for total transparency.

CountBricks transformed a 1980s ranch home with a 5-foot angled bay window overlooking the backyard. The homeowner’s key goals were added dining space and natural light. Using CountBricks AI, the contractor produced a full proposal in under 10 minutes with a final cost to add bay window of $7,650. Real-time takeoffs identified a simple header replacement, avoiding $1,200 in unexpected framing work. The project finished two days ahead of schedule, and the Rivera family now enjoys sunrise breakfasts bathed in light.
