Which Interior Door Option is Right for Your House (and Why It Matters)
If you’re shopping for interior doors in the Twin Cities, you’ve probably seen the words “pre hung door” and “slab door” thrown around like everyone magically knows what that means.
Spoiler: most homeowners don’t.
And some shady contractors really hope you don’t ask.
So let’s break this down in plain English – what each option is, how it affects interior door installation cost, and which one actually makes sense for your house.
What Is a Pre hung Interior Door?
A prehung door comes already mounted in a new frame, with hinges installed.
Think of it as a complete system:
Door
Frame
Hinges
Ready to be installed as one unit
When Prehung Doors Make Sense
New construction
Major remodels / renovations
Severely damaged or out-of-square existing frames
The Benefits
Installing a prehung door usually means:
Removing existing trim
Replacing or upgrading casing (trim)
A new door that will last for decades
An instant upgrade to how your home looks and feels
The majority of trim carpentry projects start with installing new pre hung doors
What Is an Interior Slab Door?
A slab door is just the door. No frame. No hinges.
It needs to be custom fit into your existing opening.
The Catch
Your existing door frames need to be in good shape
You want to keep all of the existing old trim
They are labor intensive to custom fit the door, hinges and handles to align with existing frames
Even when done correctly, a new slab door just looks like the same old “meh” doors that you already have
For most Twin Cities homes, slab doors are mostly installed by handyman companies after your 15 yr old kicked in one of the bedroom doors.
So… Which One Is the Better Option?
Short answer: pre hung doors are almost always the way to go.
Here’s why:
Instant update to your home
Upgraded trim styles to create a vibe
Brings the “wow” factor from friends and family
Peace of mind knowing that these new pre hung doors will last for decades
Slab doors are the choice if:
The frames are still usable and in great shape
The installer actually knows how to hang doors properly
You don’t mind paying for a project that keeps your home looking same old, same old
This is where experience matters. A lot.
The Twin Cities Reality (Older Houses Tell the Truth)
Minneapolis and St Paul homes are… charming.
They’re also:
Rarely square
Frequently settled
Full of “surprises”
In these homes:
Slab doors require precision
Pre hung doors require adjustment anyway, but change the look and feel of your home without a full remodel
There is no magic bullet – only the right approach for your situation.
Why the Choice Affects Pricing (A Lot)
Your door cost isn’t just about the door.
It’s affected by:
Install method (slab vs prehung)
Trim replacement
Hardware
Quantity of doors
Overall scope
That’s why Googling “cost per door” is a waste of time.
