- Priced per door, Masonite fiberglass door included
- Smooth for paint or woodgrain for stain
- Stock sizes or special order, written on the quote
Masonite is the fiberglass door most people have already touched, because it fills the door aisle at the big stores. Its fiberglass collections split by skin: smooth doors meant for paint, and textured doors with an oak, fir or mahogany grain meant for stain. Belleville is the classic raised-panel collection in both smooth and textured skins with a long list of glass and sidelite choices; Barrington is the premium woodgrain line with deeper detail. All are fiberglass over an insulating core, sold as a prehung unit with frame, sill and weatherstrip.
Stock versus order matters with Masonite. Common sizes in a few popular styles sit on a shelf and can be here in days. Anything else, a specific glass, a sidelite, a left-hand outswing, an odd width, is a special order with a lead time. We write stock or ordered on the quote so you know which you are getting.
We measure the opening, order through ABC Supply, our supplier, and install: old door and frame out, rot at the sill repaired, sill pan and flashing, the unit shimmed at every hinge and screwed into the framing, foamed, sealed and trimmed. Painting or staining is quoted as a separate line, or leave it primed and caulked and finish it yourself. We are the installer; options such as Therma-Tru and ProVia fiberglass doors can be priced beside it.

Situations and options
Smooth Masonite, painted
A smooth-skin door in a panel or Shaker style, painted the color you want as a separate line or by you. The usual pick for a newer house or a painted trim package.
Textured Masonite, stained
Oak, fir or mahogany grain pressed into the skin and stained to read as wood. Barrington for the deepest detail, Belleville textured for the classic raised panel.
Stock Masonite for a fast swap
When the old door has to go now, a stocked size and style in a common configuration can be installed within days. Fewer choices, no lead time.
Masonite Fiberglass Entry Door Replacement: questions, answered
Which Masonite fiberglass door should I pick?
Start with the finish. For a painted door, a smooth skin in Belleville or a Shaker design. For a stained door, a textured oak, fir or mahogany grain, with Barrington for the most wood-like detail. Then pick the panel and glass design. We confirm availability and sizes before quoting.
Are Masonite fiberglass doors in stock or ordered?
Both. A few popular styles in common sizes are stocked and can be installed within days. Specific glass, sidelites, odd sizes or an uncommon swing are special orders with a lead time. The quote says which.
Can a Masonite fiberglass door be stained?
The textured ones can. Oak, fir and mahogany grain skins take gel stain and read as wood. Smooth skins are for paint. Staining on site is quoted as a separate line, or finish it yourself.
Is a Masonite fiberglass door as good as a Therma-Tru or ProVia?
All three are fiberglass over an insulating core sold as prehung units, and all three are installed the same way. Therma-Tru and ProVia offer more woodgrain detail, more finishes and factory staining at the upper end. For a painted door in a common size, Masonite is a sound choice. We price two lines side by side when you ask.
Does Masonite make the door with sidelites?
Yes. Belleville and Barrington come with matching sidelites and transoms, in the same skin and glass, ordered as one unit so the entry arrives framed together. Sidelite units are special order.
Do you buy the Masonite door at the store?
No. We order through ABC Supply, our supplier, to the opening from our measure. If you already bought a Masonite door at a home center, we install it labor only.
