St. Louis Metro Exterior Contractor
Built from the core.
Roofing, siding, windows, and gutters — installed the way load-bearing materials are supposed to go together: measured, layered, fastened, and warrantied. Based in Ellisville, working the whole metro.

What We Install
Four trades. One crew.
Most exterior problems are really one problem wearing four different materials. We treat the roof, walls, openings, and drainage as one connected system, because water does not care which trade installed what.
Roofing
Measured tear-offs, repairs, flashing details, and full roof replacements built to shed water correctly.
Siding
Weather-resistant siding systems installed with clean lines, proper trim transitions, and durable finishes.
Windows
Replacement windows installed for fit, comfort, and energy performance with careful exterior sealing.
Gutters
Gutter and downspout systems sized and placed to move water away from walls, rooflines, and foundations.
The Atom Standard
Every job, measured at the core.
We named our build philosophy after the smallest unit of matter on purpose — get the core right and the rest of the structure holds. Three things we will not cut on, regardless of bid size.
01
Measured before quoted
We do not guess from curbside photos. Final pricing follows real measurements and real site conditions.
02
Built as one exterior system
Roof, walls, openings, and drainage work together. We look at transitions, not just isolated materials.
03
One crew lead per job
You get one accountable point of contact from walkthrough to completion and punch-list closeout.
