Calvin Mabus / Custom Garage Builder / Central Illinois

The garage that
should've been there.

I'm Calvin Mabus. I build custom detached garages across Central Illinois. Poured slabs, stick-framed on site, real siding and real trim. The garage you actually wanted when the house was built. Made for Illinois weather. Made to last.

02 / How It Goes

Slab to keys. Four steps.

Same guy from the walk-through to the day I hand you the door opener. No subs juggling schedules. No "I thought the other guy was doing that." Calvin builds it. Calvin finishes it.

Site walk
STEP 01
Walk the Lot
Free. I come out to look at where the garage is going, talk through size, doors, and how it ties to the house or driveway.
Fresh concrete slab
STEP 02
Pour The Slab
Site prep, forms, rebar, and a proper concrete pour done right. This is the part that has to be perfect. It is.
Framing interior
STEP 03
Frame & Sheet
Stick-framed on site. Trusses, sheathing, wrap, then roof. Windows and door openings cut clean for real hardware.
Finished garage exterior
STEP 04
Finish & Hand Off
Siding, trim, gutters, and the door(s). I clean the site down to the last screw. You get your driveway back.
03 / Who Shows Up

The guy on the estimate
is the guy on the build.

I'm Calvin Mabus. When you call the number on this page, it's my phone that rings. When I come out to look at your lot, I'm the guy who's going to swing the hammer. No project manager. No handoff to a crew you've never met.

If something needs to change halfway through, you don't have to explain it three times. You tell me. I'm right there.

◆ What You Get With Calvin
Answered Calls
The phone rings, I answer. If I'm on a roof, I text you back within the hour.
Straight Numbers
Free walk-through, honest estimate, no gotcha "change orders" halfway through.
Built By The Guy Who Quoted It
Every garage on this page: I quoted it, I built it, I stood there when the owner opened the door for the first time.
Clean Site
When I roll out on the last day, your driveway is spotless. Screws picked up. That's the standard.
04 / What I Build

Not just a box with a door.

Whatever you're putting in there. Two cars, three cars, a workshop, a boat, storage for the yard gear, or a garage with living space above it. I size the build around what you actually need.
