Projects throughout Warrenton's neighborhoods

Warrenton is the Warren County seat, home to roughly 8,600 residents and a mix of historic in-town properties and newer suburban subdivisions. We work across all of these areas regularly — from the older homes near the Warren County Courthouse to the newer builds in Tara Heights and east of I-70.

Missouri's climate hits Warren County hard — ice storms in winter, heavy rain and hail in spring, and summer heat that stresses roofing materials and wood trim. We select materials rated for the Midwest's temperature extremes and install them to the manufacturer's specs so they last the full rated life.

  • Hawk's Crest, Tara Heights, and Westwood Hills subdivisions

Warren County Courthouse Area

Older in-town homes near the courthouse often need roofing, window, and exterior upgrades. We handle permit pulls for Warrenton city proper.

Warren County Fairgrounds

We've worked on properties throughout the surrounding neighborhoods — many homes in this area have wood siding and fascia due for replacement.

I-70 Corridor (Exit 188)

Newer developments east of I-70 feature newer construction that still needs gutters, siding touch-ups, and window seal repairs as homes settle.

Warrenton R-III Service Area

Many of our clients are families in the Warrenton school district — we understand the local community and take referrals seriously.
