Exterior Doors
The non-garage exterior-door cluster (NEVER garage doors): entry, patio / sliding-glass, French and storm door cost, a pre-hung door rough-opening & size calculator, a slab vs pre-hung reference, and a steel vs fiberglass vs wood material compare. Cost tools use your own prices; the structural header for an exterior door is a pro item, not sized here.
Planning estimate: this is a planning estimate from the numbers you enter — not a bid or a contract. Window and door pricing depends on size, type, frame material, glass package, full-frame vs insert, trim, disposal, height/access and local labor. Get itemized written quotes from licensed, insured window/door installers before you commit.
Measure each opening and confirm sizes and clearances against the exact product you buy. Take three width and three height measurements and use the smallest of each; allow extra for custom sizes and waste. Sizes, clearances and rough-opening allowances vary by product and brand — read the spec sheet and the manufacturer’s data.
Typical published planning values / code minimums — NOT a certified design or a compliance sign-off. Actual egress compliance and energy performance depend on your local building code (AHJ), climate zone, the exact product’s NFRC-rated U-factor & SHGC and the installation; confirm against local code and the manufacturer’s NFRC label, and consult a pro. Structural headers for enlarged openings, whole-building heat-load / HVAC sizing and code certification are set by code and a professional — not engineered here.
