Therma-Tru Smooth-Star entry door replacement puts in a smooth fiberglass door made for paint, in raised-panel or Shaker styles. It can arrive factory painted, or we paint it as a separate line. JMB Builders measures in person, orders the door, removes the old door and frame, and installs the new unit across the Twin Cities metro and north to St. Cloud. Priced per door. Send photos for a reply within one business day, or book a free in-home estimate.
- Priced per door, Smooth-Star door included
- Factory painted or painted as its own line
- Raised-panel and Shaker styles
Smooth-Star is Therma-Tru's smooth-skin fiberglass door, and Therma-Tru positions it as the value line. It comes in raised-panel styles and a Shaker family with solid-panel, flush-glazed and simulated-divided-lite designs, in 6 foot 8 inch and 8 foot heights, with sidelites. For 2026 Therma-Tru added a three-quarter-lite flush-glazed Shaker door. The fiberglass will not dent or rust the way steel can.
The finish is the decision that matters most. Therma-Tru offers factory PrismaGuard paint in its standard colors, such as Estuary, Alpine, Obsidian, Peregrine, Arctic Ice, Canyon, Elk and Golden Wheat. Or order it ready to paint in any color you want: painting is quoted as a separate line on the quote, or leave it primed and caulked and paint it yourself, on all six sides the way Therma-Tru's instructions call for.
Under the skin is a polyurethane foam core, sold as a complete system with frame, sill and weatherstrip. Therma-Tru is on ABC Supply's entry door list; we confirm the Smooth-Star line with our ABC branch before the quote is final. We measure the opening in person, the old door stays in until the new one is here, and the door is locked the day it is set.

Ready to paint, any color
Order it unfinished to paint the exact color you want. We paint it as its own line on the quote, or you paint it yourself with the product Therma-Tru lists.
Shaker with flush glass
Smooth-Star's Shaker family includes flush-glazed and divided-lite designs, and a three-quarter-lite door new for 2026. A clean look on newer and farmhouse-style houses.
Therma-Tru Smooth-Star Entry Door Replacement — Painted Fiberglass: questions, answered
Can a Therma-Tru Smooth-Star door be painted any color?
Yes. Order it ready to paint and it takes a paint color of your choice, applied with a product Therma-Tru lists for fiberglass. Or order a factory PrismaGuard color from Therma-Tru's standard set and it arrives finished. Painting on site is quoted as a separate line.
Is Smooth-Star better than a steel door?
The fiberglass skin does not dent or rust the way steel can, and the foam core insulates the slab. A steel door can cost less and is a fair pick for a protected side door. For a front door that takes sun, rain and kids, fiberglass usually holds its finish and shape longer.
What styles does Smooth-Star come in?
Therma-Tru lists raised-panel styles and a Shaker family with solid-panel, flush-glazed and simulated-divided-lite designs. They come in 6 foot 8 inch and 8 foot heights, as single or double doors, with sidelites. For 2026 there is a three-quarter-lite flush-glazed Shaker door.
Should I get factory paint or paint the Smooth-Star door myself?
Factory paint arrives done and saves time on site, but you are limited to Therma-Tru's color set. Painting it yourself or having it painted lets you match any color. If you paint it, all six sides of the slab get finished, including the top and bottom edges.
Where can I get a Therma-Tru Smooth-Star door?
Therma-Tru sells through lumberyards and millwork distributors. We order through ABC Supply, which lists Therma-Tru among its entry door makers, and we confirm the Smooth-Star line with our ABC branch before the quote is final. We are an installer, not a Therma-Tru dealer.
Can Smooth-Star go on the back and side doors too?
Yes. It is a common pick for back, side and garage-to-house doors because it is smooth, paintable and does not dent. Each door is quoted on its own line, so you can do one now and others later with the same color written on the quote.
