Masonite is one of the most common entry doors in the Twin Cities, and most people know it from the home center shelf. Our supplier carries it too, which means the door can be ordered to your opening instead of picked from what is on the floor: the right width and height, the right swing, a jamb width that matches your wall, and the style, glass and finish you want. You never carry it home.
The common choices are a smooth fiberglass door for paint, a woodgrain fiberglass door for stain, or an insulated steel door for a back or side entry. Glass is built into the slab, so half-lite, full-lite and decorative glass are chosen when the door is ordered. Primed is the standard; factory paint or stain is an option on some styles. Common sizes are often stocked and a custom size or finish is ordered.
The install is the part that makes the door last. The old unit comes out, the sill and jamb feet are checked and rot is cut out and rebuilt, a sloped sill pan goes down, the new prehung is set plumb with shims behind every hinge and the strike, flashing tape laps over the brickmould, foam fills the gap, and brickmould and casing finish it. The door goes through ABC Supply on one order with anything else you are replacing, so it all arrives together.

What you supply

- A photo with a tape across the jamb edge so we can confirm the wall thickness
- A paint color if the door comes primed; painting is a separate line
What JMB supplies
- An in-person measure of the opening: width, height, swing and jamb width
- The Masonite prehung unit ordered through ABC Supply to fit, on one order with any other doors or windows
- Removal and haul-away of the old door, frame and trim
- Rot repair at the sill, jamb feet or subfloor as found, priced as written on the quote
- Sill pan, flashing, shims, low-expansion foam and sealant
- Brickmould outside, casing inside, hardware fitted and the strike and weatherstrip adjusted
- Photos of the finished door in your job folder
How it is priced: per door
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Fiberglass vs. steel, and smooth vs. woodgrain skin
- Glass: solid, half-lite, full-lite or decorative, built into the slab
- Primed for paint vs. factory finished
- Sidelites or a transom, which widen the unit and the opening work
- Stocked size vs. custom order, which changes the wait more than the price
- Rot at the sill and jamb feet found when the old door comes out
- Hardware: handleset, deadbolt or smart lock, and painting as a separate line
The sill close-up is the photo that matters. Soft wood at the bottom of the frame is the one thing that changes a door quote once the old unit is out.
How long it takes
A stocked size and finish arrives in days; a custom size, glass or factory finish is weeks, written on the quote. Install is about a day for one door in a sound opening, longer with rot repair.

Situations and options

Woodgrain fiberglass, stained
A woodgrain-skin fiberglass door for a stain finish, factory stained where the style offers it, for a front door that should read as wood without wood's upkeep.
Insulated steel, back or side door
A steel prehung for the working door: plain or with a small lite, primed and painted, set on a sill pan like the front door.
Masonite Entry Door Replacement: questions, answered
Do you supply the Masonite door or do I buy it?
We supply it. Our supplier carries Masonite, so we measure the opening and order the prehung unit to fit: width, height, swing, jamb width, style, glass and finish. It is a line on the quote next to the install. If you already bought one, we install that too as a labor-only job.
Is a Masonite door in stock or ordered?
Common sizes in the common styles are often stocked and arrive in days. A custom size, a particular glass design or a factory paint or stain finish is ordered and takes weeks. The lead time for your door is written on the quote, and the old door stays in until the new one is on site.
Should I pick a fiberglass or steel Masonite door?
Fiberglass for a front door that sees sun and weather or that you want stained; it does not dent and takes paint or stain. Steel for a back, side or garage door that gets used and painted; it is the value door and has a foam core like the fiberglass. Both are set on a sill pan the same way.
Can the back door match the new Masonite front door?
Yes. Order both on the same order and they arrive together, in the same finish and with hardware in the same family, so the deadbolts can be keyed alike. The back door is often the steel version in the same color while the front gets fiberglass and glass.
What glass can a Masonite entry door have?
Half-lite, three-quarter, full-lite and decorative glass designs, and obscure or privacy glass where you want light without a view in. The glass is built into the slab, so it is chosen when the door is ordered. Sidelites and a transom can be ordered as part of the same unit.
What is on a Masonite entry door quote?
The door as its own line with the style, size, swing, glass and finish; the install with the sill pan, flashing, foam, trim and hardware fitting; rot repair priced as a rate or allowance; haul-away; and painting as a separate line if the door comes primed. Nothing shows up later as an extra.
