How much do bi-fold and multi-slide doors cost?
Quick answer
Bi-fold patio doors typically cost $800 to $2,000 per linear foot, or about $5,000 to $20,000 installed for a 6- to 10-foot opening, according to HomeGuide. Multi-slide glass walls run about $900 to $1,500 per linear foot. Cutting a new opening with a structural header can double or triple the project cost.

Three ways to open a wall
All of these systems do the same job, which is to turn a large section of wall into an opening. They differ in how the panels move and where they go.
| System | How the panels move | Where they end up | Typical installed cost |
|---|---|---|---|
| Bi-fold (folding, accordion) | Panels are hinged together and fold along a track | Stacked flat at one or both ends | $800 to $2,000 per linear foot |
| Multi-slide, stacking | Each panel slides on its own track | Lined up behind one another at the side | $900 to $1,500 per linear foot for a glass wall |
| Multi-slide, pocketing | Panels slide into a cavity built into the wall | Hidden inside the wall | Same systems plus the cost of building the pocket |
| Telescoping slider | Two or more panels all move and stack | At the side or in a pocket | $1,500 to $5,000 installed |
A regular two-panel patio slider opens only half its width, because one panel is fixed. Folding systems clear nearly the whole opening. Stacking sliders leave the width of the stacked panels covered, unless they pocket into the wall. For standard two-panel doors, see our sliding patio door page.
Bi-fold doors
A bi-fold system uses 2 to 7 or more panels linked by hinges. You pull the end panel and the rest fold up behind it like an accordion. Many systems can include a swing panel, a single leaf that opens like a normal door so you can step outside without folding the whole wall. Folding glass doors are made up to about 10 feet tall and 48 feet wide.
Stacking and pocketing multi-slide doors
A multi-slide door is a large sliding system where several panels glide past one another. In a stacking system each panel has its own track. In a pocketing system the panels disappear into the wall, which usually needs at least three sections and a thicker wall built to hold them. HomeGuide lists sliding glass walls up to 50 feet wide and 10 feet tall, with single panels up to 60 inches wide.
Lift-and-slide doors
Lift-and-slide is a type of sliding hardware used on very large, heavy panels. When you turn the handle, the panel rises slightly off its weather seals and rests on rollers, so it glides with little effort. Turn the handle back and the panel drops onto the seals for a tight, weatherproof closure. Manufacturers point to the tighter seal and the ability to carry bigger glass as the benefits. The trade-offs are a higher price, a more exacting installation, and tracks and hardware that need regular cleaning and lubrication.
Cost by opening width
HomeGuide's installed prices for folding patio doors, labor and materials included:
| Opening width | Typical installed cost |
|---|---|
| 6 feet | $4,800 to $12,000 |
| 8 feet | $6,400 to $16,000 |
| 9 feet | $7,200 to $18,000 |
| 10 feet | $8,000 to $20,000 |
| 12 feet | $9,600 to $24,000 |
| 15 feet | $12,000 to $30,000 |
Top-tier custom aluminum, fiberglass or hardwood systems can pass $2,500 per linear foot. For comparison, a large conventional slider 8 to 12 feet wide runs about $4,000 to $7,000, and custom oversized sliders cost $900 to $1,200 per linear foot plus at least $100 per linear foot to install.
What drives the price
- Width and panel count. More panels mean more hardware, glass and labor. Width is the largest single factor.
- Height. Stock folding doors are usually 7 or 8 feet tall. Some makers offer 10-foot doors for tall ceilings, at a premium.
- Frame material. Vinyl is the most affordable. Aluminum is durable and low maintenance. Steel gives the slimmest, strongest frames, and wood offers natural insulation and a warm look.
- Glass. Double-pane is standard. Triple-pane, impact-rated, tinted or decorative glass adds cost.
- Motorization. Motor-driven panels cost more than manual ones.
- The opening. Fitting a system into an existing, correctly sized opening is the simplest job. Creating a new opening is the expensive part.
The header is the real project
A wide opening in an exterior wall needs a beam above it sized to carry the roof or floor load across the full span. That is a structural change, so expect an engineer's design, a permit, and a framing crew in addition to the door installer. HomeGuide notes that cutting a new opening, adding headers and beams and moving wiring or plumbing can double or triple the cost compared with a simple replacement. Permits for folding door installs usually cost $100 to $500.
Installation labor for exterior bi-fold systems runs about $600 to $2,500 or more. Lift-and-slide panels are heavy, and some homes need added structural support to carry them, so ask the manufacturer for panel weights early.
Timeline
| Scope | Typical time on site |
|---|---|
| New system in an existing opening of the right size | 1 to 2 days |
| New opening with header, framing and finish trim | 3 to 5 days or longer |
Large systems are usually made to order, so ask each supplier for a delivery date in writing before you schedule the framing work.
Locks, screens and thresholds
Folding exterior doors usually have a keyed lock on the main swing panel that drives several locking points around the frame, plus shoot bolts or two-point locks on the other panels. Lift-and-slide panels lock at several points when the handle is lowered.
Screens are part of the plan for most buyers. HomeGuide notes that a bi-fold security screen lets you leave the glass open in warm months while keeping bugs out. Ask whether the screen is retractable and where it stores when not in use.
Thresholds deserve a careful look. A flush or low sill makes the indoor and outdoor floors read as one surface. Ask the installer how that sill will be drained and flashed. Ask what water resistance the system was tested to and whether that rating applies to the sill you are buying.
Energy and safety glass rules
ENERGY STAR defines a sliding glass door as one with one or more manually operated glass panels that slide, so multi-slide and lift-and-slide systems fall under the sliding door rules. Under Version 7.0, they must meet the window limits for your climate zone: a U-factor of 0.22 or lower in the Northern zone, 0.25 in North-Central, 0.28 in South-Central and 0.32 in the Southern zone, with air leakage of 0.3 cfm per square foot or less. The specification does not set a separate category for folding doors, so ask for the NFRC label on any bi-fold system you price and compare the U-factor with the same numbers.
The International Building Code treats glass in all fixed and moving panels of swinging, sliding and bi-fold doors as a hazardous location, so every pane in these systems must be safety glazing. In hurricane regions, look for impact-rated units; our guide to impact windows explains the ratings, and the windows overview covers glass packages in more depth.
Is a bi-fold or multi-slide door worth it?
These are among the most expensive door projects in a house. They make the most sense when the room opens onto a patio, deck or pool area you use often, and when the wall can take a wide opening without major rework. If the budget is tight, a pair of French doors or a three- or four-panel slider gives a wide opening for much less. If you are also planning other changes to the house, GOLDGCP's in-house architects can help work out whether a wide opening fits the structure before you order.

Frequently asked questions
How much do bi-fold patio doors cost?
HomeGuide puts bi-fold patio doors at $800 to $2,000 per linear foot installed. That works out to about $6,400 to $16,000 for an 8-foot opening and $9,600 to $24,000 for a 12-foot opening. Custom high-end systems can pass $2,500 per linear foot.
What is the difference between a bi-fold and a multi-slide door?
Bi-fold panels are hinged together and fold like an accordion to one or both sides. Multi-slide panels each ride on their own track and slide behind one another, or into a pocket in the wall. Folding systems clear nearly the whole opening; stacking sliders leave the stacked panels in view.
What is a lift-and-slide door?
It is a sliding door whose handle lifts the panel off its seals onto rollers so it can move, then lowers it back onto the seals when closed. That allows very large, heavy panels and a tight weather seal. It costs more and needs careful installation and regular track cleaning.
Do I need a permit for a bi-fold door?
Usually, when the work creates a new opening or changes the structure. A wider opening needs a properly sized header, which most building departments review. HomeGuide puts permit fees for folding door installations at about $100 to $500, depending on the city.
How long does it take to install a multi-slide door?
In an existing opening of the right size, about 1 to 2 days. When a new opening and header are needed, plan for 3 to 5 days or longer on site. Custom systems are made to order, so ask about delivery time before you book the work.
Are bi-fold doors energy efficient?
They can be, with double-pane or triple-pane low-E glass and good seals. Ask for the NFRC label on the exact system you are pricing. For sliding systems, ENERGY STAR Version 7.0 requires a U-factor between 0.22 and 0.32 depending on climate zone.
How we calculate these prices
GOLDGCP starts from national price ranges for each job, taken from published 2026 cost guides and checked against local price guides where they exist. To get a local price, we multiply the national range by the construction cost factor for the metro from the U.S. Army Corps of Engineers Area Cost Factors (US average = 1.00). For ZIP codes outside the 50 largest metros, the calculator uses the state's price level from the Bureau of Economic Analysis Regional Price Parities. Ranges include labor and standard materials but not unusual site conditions, so a written quote after an inspection is always the final price.
