When Every Other Option Is Exhausted
You're on the 12th floor. The passenger elevator cab is 51 × 68 inches — your couch won't fit at any angle. There's no freight elevator. The stairs are 14 flights of 30-inch-wide switchbacks. The only remaining option is the window.
High-rise window delivery sounds extreme, but it's a well-established service in major cities. Professional hoisting companies do this daily — it's their entire business model.
How High-Rise Hoisting Works
Method 1: Rope and Pulley (2–6 Floors)
- A pulley is anchored to the building above the target window (roof edge or higher-floor balcony)
- Ropes are attached to the furniture with professional rigging (not random knots)
- A ground team guides the item away from the building during ascent
- A window team guides the item through the opening at the correct floor
- 4–6 people needed for a safe operation
Method 2: Exterior Lift / Swing Arm (6–20+ Floors)
- A swing-arm crane or platform hoist is mounted on the roof or set up at ground level
- The item is loaded onto the platform or attached to the crane cable
- The hoist raises the item to the correct floor
- A window team guides it through the opening
- This method handles the heaviest items (pianos, appliances, oversized furniture)
Method 3: Mobile Crane (Very High or Very Heavy)
- A truck-mounted crane parks below the building
- The crane lifts items directly to the correct window
- Street closure permits may be required
- This is the most expensive option but handles any weight and any floor
What It Costs
- Rope and pulley (2–6 floors): $100–$500 per item
- Exterior lift (6–15 floors): $300–$1,500 per item
- Mobile crane (any height): $1,000–$5,000+ (includes crane rental, operator, permits)
Pricing depends on: floor height, item weight, building access difficulty, and whether street permits are needed. Always get multiple quotes.
Building Requirements and Permits
- Building approval: Required in virtually all high-rise buildings. Submit a request to building management with the moving company's insurance certificate.
- Street permits: Crane operations require city permits if the crane is on a public street. The hoisting company typically handles this.
- Insurance requirements: Buildings require the hoisting company to carry $1M–$5M in general liability. Verify before booking.
- Time restrictions: Hoisting may be limited to specific hours (often 8 AM–4 PM weekdays) to minimize disruption.
- Weather cancellation: High winds cancel all exterior hoisting operations. Have a backup date.
Window Preparation
The window through which furniture enters must be prepared:
- Remove the sash or panels (see our window extraction guide)
- Pad the window sill and frame with moving blankets — the item will slide across these surfaces
- Clear a landing zone inside the room — at least 6 feet of clear space from the window
- Protect the floor below the window — heavy items set down can crack tile or dent hardwood
- Verify the window opening is large enough — check with the calculator
Items Commonly Hoisted Through High-Rise Windows
- Grand and upright pianos: The original (and still most common) reason for professional hoisting
- Large couches: Couches that won't fit the elevator
- King mattresses: When the elevator and stairs both fail
- Custom/oversized furniture: Pieces built to order that weren't designed for standard building access
- Hot tubs / jacuzzis: For penthouse or balcony installation
- Safes: Heavy + large = always a hoist job above 2 floors
How to Find a Hoisting Company
- Search for "furniture hoisting" or "piano hoisting" + your city
- Ask your moving company — most full-service movers either offer hoisting or partner with a specialty company
- Ask building management — they've seen this before and can recommend companies that have worked your building
- Verify insurance, licenses, and references before booking
Before committing to window delivery, double-check every other route: doors, freight elevator, stairs, and disassembly options. Window hoisting is the most expensive option and should be the last resort.
FAQ
Is window hoisting safe?
When performed by licensed professionals with proper rigging and insurance, yes. Hoisting companies use rated slings, cables, and equipment designed for the weight. The risk of damage or injury is very low with a professional crew. DIY hoisting at height is extremely dangerous and should never be attempted.
Can any window be used for furniture delivery?
The window must be operable or have a removable sash/panel. It must be large enough for the item — check window sizes. Some building facades have windows that can't be opened (sealed glass) — these are not viable for delivery without professional glass removal and reinstallation.
