Plastpro fiberglass entry door replacement puts in a fiberglass door known for what is not in it: the slab edges are composite, not wood, and a composite frame is offered to match, so nothing at the bottom of the door or jamb can rot. Smooth or woodgrain skins, paint or stain. JMB Builders measures, orders through ABC Supply and installs across the Twin Cities. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per door, Plastpro door included
- Composite slab edges; composite frame available
- Smooth for paint or woodgrain for stain
Most fiberglass doors have wood inside the edges of the slab, the stiles and rails the skins are glued to, and hang in a wood frame. That wood is where water does its work: the bottom rail swells, the jamb feet go soft, the sill pulls away. Plastpro's answer is to take the wood out. Its slabs use composite edges that do not absorb water, and it sells a composite frame and sill to go with them, so the parts that sit in the slush are not wood at all.
The doors come smooth for paint or in woodgrain skins such as mahogany, oak and fir for stain, in panel designs from six-panel and Craftsman to Shaker and flush modern, with glass designs and matching sidelites. The core is insulating foam. Plastpro sells through lumberyards and distributors, and the door is ordered as a prehung unit to the opening.
We measure the opening, order through ABC Supply, our supplier, and install: old door and frame out, rotted sill framing and subfloor repaired, sill pan and flashing, the unit shimmed at every hinge and screwed into the framing, foamed, sealed and trimmed. Painting or staining is a separate line, or leave it primed and caulked and finish it yourself. We are the installer; options such as Therma-Tru and ProVia can be priced beside it.

How it is priced: per door
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Smooth vs. woodgrain skin, and the panel design
- Wood frame vs. Plastpro's composite frame
- Glass in the door, and sidelites with it
- Rot in the sill framing and subfloor under the old door
- Siding type at the opening: lap, stucco or brick
- Hardware: a basic lockset vs. a handle set or multipoint lock
- Painting or staining, quoted as a separate line
Send a close-up of the bottom corners of the old door and jamb. If they are rotted, say so; the composite frame is the line we add for that opening.
How long it takes
One Plastpro door in a sound opening: about a day on site. Rot repair adds time. Lead time depends on the order and is written on the quote.

Situations and options
Plastpro with the composite frame
Door, jamb and sill with no wood in the wet zone. The pick for a door that sits at grade, under a short overhang, or where the last frame rotted out.
Smooth Plastpro, painted
A smooth skin in Shaker, Craftsman or flush modern, painted as a separate line or by you. Composite edges mean the bottom of the slab never swells under the paint.
Woodgrain Plastpro, stained
Mahogany, oak or fir grain skins that take stain, with sidelites to match. The wood look without wood anywhere water can reach it.
Plastpro Fiberglass Entry Door Replacement: questions, answered
What is different about a Plastpro door?
The edges of the slab are composite instead of wood, and Plastpro offers a composite frame and sill to hang it in. Water that would soak into a wood stile or jamb foot has nothing to soak into. The skins, foam core and glass choices are otherwise like other fiberglass doors.
Does a Plastpro door come with a composite frame?
It is an option. You can order the slab in a standard wood frame or in Plastpro's composite frame. For a door at grade or one that has rotted before, we put the composite frame on the quote.
Can a Plastpro door be stained?
Yes, the woodgrain skins in mahogany, oak and fir grain take stain. Smooth skins are for paint. Finishing on site is quoted as a separate line, or do it yourself; all six sides of the slab get finished.
How does Plastpro compare to Therma-Tru?
Both are fiberglass over a foam core with smooth and woodgrain skins. Therma-Tru has more factory finishes and a bigger decorative glass program; Plastpro's edge is the composite stiles and frame for a door in a wet spot. We price the two side by side when you are deciding.
Where is Plastpro sold?
Through lumberyards and building-supply distributors rather than big-box stores. We order through ABC Supply, our supplier, to the opening from our measure, and confirm the line before the quote is final. If you already bought a Plastpro door, we install it labor only.
What if the subfloor under my door is already rotted?
The soft wood comes out and the sill framing and subfloor are rebuilt before the new unit goes in, quoted from what we find once the old door is out. Then the composite-frame Plastpro sits on a sill pan so it does not happen again.
