A&S Contracting:
Built on Honest Work
in Central Missouri
A&S Contracting Services is a licensed and insured general contractor serving residential and commercial clients within 50 miles of Warrenton, MO. We self-perform roofing, siding, gutters, drywall, windows, and full-scale renovations — no trade gaps, no subcontracted surprises.
Who is A&S Contracting
Services?
Most contractors specialize in one trade and refer everything else out. When your roofer doesn't talk to your siding crew, and neither one talks to your drywall installer, you end up coordinating four separate timelines, four separate warranty claims, and four separate trucks showing up whenever they feel like it.
A&S was built to eliminate that problem. As a general contractor, we manage every phase of a project — planning, permits, scheduling, execution, and final walkthrough — so homeowners across Warren County and central Missouri get consistent quality from a single accountable team.
"We don't chase every job in St. Louis — we focus on being genuinely excellent in the 50-mile circle we know well."
See What We DoWhat does A&S Contracting
actually stand for?
Honest Scoping
We give you a written estimate that reflects the real project — no low bids that balloon after the first week. If something changes after demo, we tell you immediately and get written approval before continuing.
Schedule Accountability
We set project timelines and hold to them. If weather or material delays shift a start date, we contact you before you have to call us — not the other way around. Warrenton area homeowners should never be left wondering what's happening with their job.
Finish-Quality Work
Our crews work to the same standard whether it's a $1,400 gutter job or a $60,000 full interior renovation. The final walkthrough isn't over until you've looked at every edge, seam, and surface — and signed off on it.

and central Missouri
What kind of contractor
is A&S — and what aren't we?
- We are: A licensed Missouri general contractor who manages projects start to finish and holds our own crew accountable to the same standards on every job.
- We're not: A national franchise with a call center in another state. Your project is managed locally, by the same people you met at the estimate.
- We do: Provide written estimates, written contracts, proper permits, and documented material selections before any work begins.
- We don't: Start work with a handshake and a vague price range. If a contractor can't give you a written number, that's a warning sign — not standard practice.
- We serve: Warrenton, Warren County, and a 50-mile radius across central Missouri — and we know this territory's building codes, weather patterns, and material demands specifically.
