Therma-Tru did not have one universal 2017 price list: prices varied by door series, size, glass, finish, retailer, and installation scope. As a historical U.S. budgeting estimate, a basic fiberglass entry door could cost about $400-$1,500 for the door unit, while a professionally installed replacement often totaled $900-$2,800 in 2017 dollars.
These estimates are not a verified manufacturer catalog or an exact quote. Use the ranges as historical comparisons, not as current replacement pricing.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic fiberglass door unit | $400 | $850 | $1,500 | 2017 estimate; standard size and limited glass |
| Decorative or glazed unit | $800 | $1,500 | $2,800 | More glass, upgraded series, or finish |
| Installed replacement | $900 | $1,700 | $3,500 | Includes typical labor; site repairs can add cost |
| Door slab only | $200 | $500 | $1,000 | May require compatible existing frame |
What a Therma-Tru entry door cost in 2017
A standard 3-foot-by-6-foot-8-inch fiberglass entry door with a basic finish and little or no decorative glass generally fell near $400-$1,000 for the door unit. A prehung unit, which includes a frame and hinges, often ranged from $600-$1,500. Larger, custom, or glass-heavy configurations could exceed $2,000 before installation.
For a straightforward replacement, the combined 2017 price was commonly around $900-$2,800, with a midpoint near $1,700. Regional labor rates and whether the existing frame could be reused affected the total. Assumptions: standard single entry door, U.S. 2017 dollars, ordinary access, no major framing repairs.
How glass, frame, and labor appeared on the quote
Quotes separated the door package from installation and site work, although retailers did not always itemize every charge. A slab-only price should not be compared directly with a prehung, installed package. The following ranges are historical planning estimates, not fixed Therma-Tru list prices.
| Quote item | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Fiberglass slab | $200 | $500 | $1,000 | Door only; varies by series and finish |
| Frame and hardware | $150 | $350 | $700 | Frame, hinges, basic lock preparation |
| Decorative glass | $100 | $400 | $1,000 | Glass design and size determine premium |
| Installation labor | $250 | $550 | $1,000 | Removal, fitting, fastening, and basic sealing |
| Disposal and trim | $50 | $175 | $400 | Old door removal, haul-away, or trim work |
Glass and frame upgrades can change the package price as much as the door material itself. Labor pricing reflects a typical replacement, not a new opening or extensive carpentry.
How door size, glass, and frame condition changed the price
Size and configuration were major price drivers. A standard single door usually cost less than a 3-foot-by-8-foot unit, a sidelight combination, or a double entry system. Custom width, height, swing, or jamb depth could require special ordering and raise both product and installation charges.
Glass options also widened the range: a small decorative insert could add roughly $100-$400, while elaborate or larger glass designs could add $500-$1,000 or more compared with a basic configuration. If rot, water damage, or an out-of-square opening required more than about 2-4 hours of extra carpentry, labor and materials could add $150-$600. Confirm the exact size, glass pattern, and frame scope on the written quote.
When installation labor pushed the total above the door price
A qualified installer might need about 4-8 hours for a standard single-door replacement, including removal, leveling, fastening, insulation, and sealing. In 2017, labor rates often translated to roughly $250-$700 for a routine job; complicated trim or framing work could take a full day or longer.
Installing a new door into a previously unopened wall is a different project from replacing a unit in an existing opening. Structural framing, exterior siding, interior drywall, and weatherproofing can add substantial expense. Ask whether the labor quote includes removal, disposal, trim, lock installation, and cleanup.
How 2017 Therma-Tru quotes varied by U.S. region
Historical estimates varied with local wages, contractor availability, delivery distance, and housing conditions. Compared with a typical national quote, a major coastal metro could run about 10%-25% higher; a lower-cost rural market might be 5%-15% lower, although fewer nearby installers could erase that difference.
These are broad comparisons, not regional price records for every Therma-Tru dealer. A quote in a high-cost market could also reflect higher disposal fees or additional code-related work. Compare at least two local written bids with the same door configuration and installation scope.
Three example door packages and their historical totals
A basic, standard-size prehung fiberglass unit with minimal glass might have totaled about $1,050: a $650 door package, 5 hours of labor at roughly $70 per hour, and about $50 for disposal or supplies.
A midrange entry with decorative glass and a new frame could have totaled around $1,850: approximately $1,100 for the package, 7 labor hours at $85 per hour, and $155 for trim or haul-away. A larger door with sidelights and more involved fitting could reach $3,200-$4,500, depending on custom components and 10-14 labor hours. These examples illustrate 2017-dollar scenarios, not confirmed retailer transactions.
What removal, trim, and hardware added to the bill
Old-door removal and disposal could add roughly $50-$200 if not included in the installation price. New casing, threshold work, weatherstripping, and paint or stain touch-ups might add another $75-$400, particularly when the old trim could not be reused.
Locks were sometimes included as basic hardware and sometimes priced separately. A lockset upgrade could add about $50-$250, while a new storm door or extensive exterior trim would be a separate project. Check each accessory and finishing task before comparing package totals.
How to compare a 2017 list price with a current quote
First identify whether the old figure covered a slab, prehung unit, or installed project; those prices are not interchangeable. Then match series, size, glass, finish, hardware, and frame details. A 2017 price is historical and should not be treated as a present-day offer: current material, shipping, and labor costs differ, and a current dealer quote is needed for a replacement budget.
To control the project price, keep the opening and configuration standard where practical, avoid decorative upgrades that are not needed, and ask whether the existing frame is sound enough to retain. Do not choose slab-only pricing if the jamb is damaged or incompatible. The most useful comparison is between complete quotes with identical specifications and clearly stated exclusions.
