You’re replacing a garage door and the options are nothing like they were the last time you dealt with this. Sectional or carriage house. Steel or wood. Polystyrene or polyurethane. Panel style, insulation rating, opener type. Most of what you find when you search is organized to move product. This is organized to help you decide.
Sectional doors: why they’re the default answer
A sectional door is the horizontal-panel door on tracks that curves up along the ceiling when it opens. Roughly 80% of replacement doors installed in North America are insulated steel sectionals. That’s not a marketing stat. It’s the answer the market has converged on because it works across climates, budgets, and house styles. Most buyers reading this should buy one. What follows is the context for whether you’re the exception.
A mid-grade insulated steel sectional runs $1,500 to $3,200 installed in 2026 for a standard double-car opening. That’s where most replacement projects land.
Insulation: the choice most buyers get wrong
Inside the sectional category, there’s a split that matters more than panel style or color: polystyrene versus polyurethane insulation.
Polystyrene is a foam board slid into the panel cavity. It achieves R-6 to R-10. Polyurethane is injected as a liquid, expands to bond with both steel skins, and reaches R-12 to R-18 in the same panel thickness. The polyurethane version is also structurally stiffer. The bond to both skins adds rigidity beyond the thermal benefit.
For a detached, unheated garage where the door is mostly a weather and security barrier, polystyrene is fine. Save the money. For an attached garage in a climate with real winters or real summers (freeze-thaw regions in the north, humid coastal areas, hot-dry desert climates like the Southwest) polyurethane is the correct answer. The thermal gap between the two is large enough to show up on your utility bill and in your comfort if there’s living space near the garage.
If there is living space directly above the garage, the three-layer polyurethane door at R-16 to R-18 is worth the step up in price. That insulation class puts the door in the same thermal range as an insulated exterior wall.

Panel style: long vs short
Long-panel doors have wide, uninterrupted horizontal panels. Short-panel doors subdivide those same panels into a grid of squares, the traditional look most people picture. At the entry level, the price is the same either way.
The failure mode is not the same. A dent on a long-panel door lands in the middle of a wide flat surface where it reads immediately. The same dent on a short-panel door is partially broken up by the surrounding pattern. If the driveway gets hail, if there’s a basketball hoop above the opening, or if there’s regular traffic close to the door, short panels hide damage better. That’s a real consideration, not a purely aesthetic one.
Carriage house and full-view doors
These are the two style upgrades most buyers consider when a plain steel sectional looks too utilitarian for the house.
Carriage house doors are still steel sectionals underneath (same tracks, same springs, same opener). What changes is the exterior: overlay hardware, decorative hinges and handles, sometimes a plank pattern stamped or applied to the surface. They’re the right choice for houses with specific architectural character (Craftsman, Tudor, farmhouse) where a flat long-panel door would look wrong. Budget $3,500 to $7,500 installed once window sections and overlay hardware are included on premium lines.
Full-view aluminum doors are the glass-and-aluminum-frame doors common on modern homes and commercial storefronts. They’re visually distinctive and expensive, sometimes exceeding $10,000 for wider openings. Two failure modes to know: the insulation value is low because the panels are mostly glass, and on the wrong house they read as a commercial installation. They’re right for a specific modern aesthetic on the right structure. They’re not a general upgrade.
Wood doors
Custom wood garage doors run $4,000 to $15,000 installed depending on species and hardware. They also require refinishing every three to five years. That refinishing is not optional. A neglected wood door in a humid coastal climate or a region with hard winters will swell, crack, and eventually delaminate.
Wood is the right answer for one buyer: someone with a specific architectural home where a steel carriage-house replica would be visibly wrong, and who has both the budget for the door and the discipline to maintain it. For everyone else, a carriage-house steel door delivers a comparable look at a fraction of the cost and none of the refinishing schedule.
Rolling steel doors
Rolling steel doors coil above the opening instead of running along horizontal tracks. They’re standard on storage units and warehouses. For residential use, they’re almost always the wrong choice. The aesthetics read as commercial, insulation options are limited, and the operating hardware costs more to service. The side-by-side comparison of rolling steel and sectional doors covers the edge cases in detail.
The legitimate exceptions: a detached workshop, a barn conversion, or a garage where ceiling depth is too shallow for sectional tracks. In those cases, rolling steel is a real answer. Otherwise, skip it.
The opener is part of this decision
Door weight determines opener size, which is why you can’t fully separate the two decisions. For a double-car door, a solid wood door, or an insulated steel door over 16 feet wide, three-quarter horsepower is the minimum to avoid premature motor burnout.
Drive type matters if the garage is attached to living space. A chain-drive opener runs $350 to $500 installed and operates above 70 dB, audible through most shared walls. A belt-drive opener runs $450 to $650 installed and operates around 50 dB. A direct-drive opener runs $650 to $900 or more installed and is the quietest of the three: the motor travels along a stationary rail rather than driving a separate chain or belt, and most units carry a lifetime motor warranty. Skip screw drives. The grease on the threaded rod stiffens in cold weather, gets loud in heat, and parts are increasingly hard to source. For a side-by-side breakdown, the belt vs chain vs direct drive comparison covers the tradeoffs clearly.
On the spring side: standard torsion springs are rated to 10,000 cycles, roughly 7 to 10 years of daily use. High-cycle springs rated to 25,000 to 100,000 cycles cost $75 to $150 more upfront. If you’re paying for a twenty-year door, spending the extra $100 on springs that won’t need replacement in year nine is sound math. Torsion springs are under extreme tension and must be installed or replaced by a qualified technician. This is not a DIY task.
Before you buy new: the repair check
If your existing door still functions but has cosmetic damage or a single broken component, get a repair quote first. The threshold: if a repair quote exceeds 50 percent of what a same-tier replacement door would cost installed, replacement is the better financial decision. A full safety inspection will surface whether a repair is viable or whether the door has accumulated enough wear that replacement is the cleaner outcome.
Three questions that narrow the decision
One: is the garage attached to the house? If detached, buy a polystyrene-insulated steel sectional in the $1,100 to $1,700 range. Done. If attached, continue.
Two: does the house have specific architectural character (Craftsman, Tudor, farmhouse, mid-century modern)? If yes, budget for a carriage-house or full-view door that fits the architecture. If no, a polyurethane steel sectional in the $1,700 to $2,900 range is the right answer. Choose short panels if the door faces regular impact risk.
Three: is there living space above or immediately adjacent to the garage? If yes, pay for the three-layer polyurethane door at R-16 to R-18 and pair it with a belt or direct-drive opener. If no, a two-layer polyurethane door and a chain-drive opener is sufficient.
For most buyers, the answer is an insulated steel sectional with a polyurethane core (short or long panels depending on the driveway) paired with a belt-drive opener and high-cycle torsion springs. Total installed cost lands between $2,000 and $3,500. That’s the middle of the market. For most houses, that’s exactly where the purchase belongs.

Frequently Asked Questions
What type of garage door is best for an attached garage?
An insulated steel sectional door with a polyurethane core is the right answer for most attached garages. Polyurethane insulation reaches R-12 to R-18, which is meaningfully better than the polystyrene alternative and adds structural rigidity to the panel. If there is living space above or directly adjacent to the garage, pay for the three-layer version at R-16 to R-18 and pair it with a belt or direct-drive opener to control noise.
What is the difference between polystyrene and polyurethane garage door insulation?
Polystyrene is a foam board inserted into the panel cavity and achieves R-6 to R-10. Polyurethane is injected as a liquid, expands to bond with both steel skins, and reaches R-12 to R-18 in the same panel thickness. The polyurethane version is also structurally stiffer. For detached, unheated garages the polystyrene version is adequate; for attached garages in climates with real seasonal temperature swings, polyurethane is the correct choice.
How much does a new garage door cost installed in 2026?
A mid-grade insulated steel sectional door runs $1,500 to $3,200 installed for a standard double-car opening. Carriage-house premium lines with window sections and overlay hardware typically land between $3,500 and $7,500 installed. Full-view aluminum doors on wider openings can exceed $10,000. Custom wood doors start around $4,000 and can reach $15,000 or more depending on species and hardware.
Should I repair my existing garage door or replace it?
If a single repair quote exceeds 50 percent of what a same-tier replacement door would cost installed, replacement is usually the better financial decision. If the door structure is sound and the issue is a single component, a broken spring, a damaged panel section, or a failed opener, repair is likely the right call. A safety inspection will tell you whether the door has accumulated enough wear to make replacement the cleaner outcome.
Are carriage house garage doors actually different from regular sectional doors?
Mechanically, no. Carriage house doors use the same tracks, springs, and openers as standard steel sectional doors. What changes is the exterior: overlay hardware, decorative hinges and handles, and sometimes a plank or board pattern stamped or applied to the surface. The upgrade is aesthetic, not structural. They’re the right choice when the house has specific architectural character where a plain steel door would look mismatched.
When does a rolling steel garage door make sense for a home?
Rolling steel doors are the right answer in a small number of residential situations: a detached workshop or barn conversion, or a garage where ceiling depth is too shallow for standard sectional tracks. For a standard attached residential garage, the aesthetics read as commercial, insulation options are limited, and the hardware costs more to service. In most residential replacement scenarios, a sectional door is the correct choice.
