“Had A&S replace the entire roof on our home after hail damage last spring. They came out fast, gave us a fair written quote, and the crew was professional from start to finish. Roof looks incredible and our insurance claim went smoothly with their documentation.”

Know The Signs
When does your Warren County project need a general contractor?
A&S Contracting Services steps in when a project touches more than one trade—an addition, a whole renovation, a storm rebuild, or a commercial build-out. The moment framing, roofing, drywall, and finishes all have to be scheduled, permitted, and inspected in the right order, you need one manager accountable for the budget and the timeline, not a homeowner playing dispatcher.
The hardest part of a big project isn’t any one trade—it’s getting all of them to line up in the right order.
Multi-trade project
An addition or renovation that needs framing, roofing, drywall, and finishes all coordinated.
Permits & inspections
Work that requires pulled permits and passed inspections you would rather not manage.
Nobody owns the schedule
Subcontractors on their own calendars leave the timeline with no one in charge.
Commercial build-out
A storefront or office fit-out that has to open on a firm date.

Why It Matters
What makes A&S accountable from start to finish?
A&S Contracting Services self-performs most of the trades it manages—roofing, siding, drywall, and interior work—so the general contractor and the crew are the same company. There is no subcontractor to blame for a missed day. One team plans the job, pulls the permits, runs the schedule, and answers for the result at the final walkthrough.
- One in-house team. Because we self-perform the core trades, scheduling and quality stay under one roof instead of scattered across subs.
- Permits and inspections handled. We pull the permits, coordinate inspections, and keep the project moving through each sign-off.
- Licensed & fully insured. You work with a licensed Missouri general contractor carrying full insurance on every project, residential or commercial.

In Their Words
What do Warren County clients say about A&S on bigger projects?
Real reviews from A&S Contracting Services renovation, addition, and full-project customers across Warren County.
“We needed new siding and gutters on our place outside Warrenton. A&S was the most professional of the three contractors we got quotes from — they showed up when they said they would, communicated clearly, and finished ahead of schedule. Very happy we went with them.”
“These guys did a full interior renovation — drywall, trim, paint — on a room addition at our house near Wright City. Great craftsmanship, clean job site every day, and they handled everything themselves without subbing it out. Will absolutely hire again.”

The Difference
Why hire A&S instead of managing subcontractors yourself?

With A&S self-performing the core trades, the schedule stays under one roof and one company answers for the finished result.
Being your own GC
- Coordinating separate subs on clashing schedules

- No single party accountable for the result

- Permits, schedule, and inspections handled

Good Questions
What do Warren County clients ask about general contracting?
How much does a general contracting project cost in Warrenton?
A&S Contracting Services prices each project from its actual scope—the trades involved, materials, permits, and timeline—laid out in a written, itemized estimate. A room addition, a whole renovation, and a commercial build-out are very different numbers, so we scope the work on site rather than quote a general contractor by the square foot over the phone.
Do you handle permits and inspections?
Yes. A&S Contracting Services pulls the required permits and coordinates inspections through each phase of the project. Warren County and its municipalities each have their own requirements, and part of hiring a general contractor is not having to learn them—we keep the project moving from permit to final sign-off so nothing stalls on paperwork.
Do you take on both residential and commercial projects?
Yes. A&S Contracting Services manages residential renovations and additions as well as commercial build-outs across Warren County. The core skill is the same: sequencing trades, holding the schedule, and staying accountable for the budget—whether it is a family's addition or a storefront that has to open on a set date.
Do you self-perform the work or subcontract it?
A&S Contracting Services self-performs the core trades—roofing, siding, drywall, and interior work—which is the whole point of hiring us. When a specialty trade like electrical or plumbing is required, we bring in licensed partners and manage them, so you still have one company accountable for the schedule and the finished result.
How do you keep a project on schedule?
A&S Contracting Services builds one schedule and sequences the trades so each phase is ready for the next. Because we self-perform most of the work, we are not waiting on a subcontractor's separate calendar. You get a single point of contact who tracks the timeline and tells you where the project stands instead of guessing.
Are you a licensed general contractor in Missouri?
Yes. A&S Contracting Services is a licensed Missouri general contractor and carries full insurance on every project. That licensing and coverage protect you on larger jobs where multiple trades, permits, and inspections are in play, and it means the company managing your Warren County project is accountable for it in writing.
