Builder-Grade Hollow Core
Cardboard honeycomb interior, lightweight, lets sound straight through.
Solid Core Upgrade
Dense engineered core, quiet, substantial feel — the single biggest upgrade in how a home feels.
Most Colorado homes built since the '90s came with hollow-core doors on every room.
Anatomy of a Perfect Slab Swap
1. Hinges mortised to match
The new door hangs exactly where the old one did.
2. Hardware bored precisely
Your knobs and locksets line up and latch clean.
3. Reveal shimmed even
Uniform gaps all the way around, no rubbing, no light leaks.
4. Trim untouched
No painting, no patching — the room looks finished because nothing else moved.

Slab vs Prehung — which do you need?
The side-by-side breakdown most door companies won't give you.
When to choose each
Choose a Slab if…
your frames are straight and solid and you just want a new look — the most affordable upgrade for bedrooms, baths, and closets.
Choose Prehung if…
your frames are damaged, painted shut, out of square, or you want everything new. Common in older Front Range homes that have settled.

We handle the hard part
Hanging a slab so it closes flush and latches clean is the hard part — and where DIY usually goes wrong. We mortise the hinges, drill the hardware, shim the reveal, and match your existing trim so the new door looks and works like it's always been there. Removal, install, and cleanup included.

What Colorado homeowners are saying.
I highly recommend the Colorado Door Store! Jason was great to work with, friendly, dependable, did a fantastic job on two large door and trim installs, and provided competitive pricing. Five stars all around!
Repeat customer. I met Jason over 10 years ago when he installed new doors at my home. His work is top notch. My home is older and not standard, and Jason was creative and put on a beautiful new door for me. I trust him completely.
Jason is the best! Seams are perfect inside and out. You can hardly tell he was in our house, his prep and cleanup were impeccable.
