Estimates and sizing typicals, not guarantees

Results are deterministic estimates from your inputs, your prices and standard reference conventions (project cost = door price + labor + add-ons − trade-in, ×(1+contingency); cost by size = width × height × your $/sq ft + install; spring life = rated cycles ÷ (cycles/day × 365); door weight = area × labeled lb/sq ft; rough opening = door size + labeled clearances). Real projects vary — verify measurements and figures before relying on them.

Not a bid, not a price index

Cost tools give planning estimates from your own prices, not bids or contracts, and we store no door, opener or labor price list, no regional cost index and no installer directory. Cost bands are a labeled sanity guide only. Get itemized written quotes from licensed, insured garage-door installers.

⚠️ Spring, cable & off-track safety

Garage-door torsion and extension springs and cables store extreme mechanical energy. A failing spring or cable can cause serious injury or death. Spring, cable and off-track work must be done by a trained garage-door technician with the correct winding bars. These tools are cost estimators — not a DIY repair or safety guide. Do not force a stuck or off-track door.

Openers — electrical

A hard-wired opener circuit should be installed by a licensed electrician and must meet local code. On this site the wired circuit is only a user-entered cost line-item; the opener tools do not size electrical loads.

Sizing values — labeled typicals

Material weight, opener HP bands, R-value bands, spring cycle-life ratings and framing clearances are labeled industry planning typicals — confirm against your door’s spec sheet and a qualified installer before ordering parts. Rough-opening and clearance figures are planning typicals, not a structural design; the framing and wind-load rating must be confirmed with a qualified builder and local code.

Insulation payback — illustrative only

The insulated-vs-non-insulated payback tool is illustrative math on the figures you enter, not an energy audit. Savings depend on your climate, how the garage is used and energy prices; the door’s R-value is only one factor.
