Answers About A&S Contracting
— No Runaround

A general contractor (GC) is a licensed professional who manages construction projects from planning to completion — coordinating materials, permits, inspections, and trade crews under one contract. For homeowners in Warrenton, MO, hiring a licensed GC means one accountable point of contact instead of juggling four separate specialty trades. A&S Contracting Services is a licensed and insured Missouri GC serving a 50-mile radius.

Yes. A&S Contracting Services is a licensed and insured general contractor in the state of Missouri. We carry general liability insurance and can provide proof of coverage before any project begins. Licensing in Missouri means we are authorized to pull permits, oversee structural work, and take legal responsibility for the projects we manage.

Submit a request through our contact form at a-s-contracting-services.pageone.cloud/contact/ or call us directly. We'll confirm receipt within one business day and schedule an on-site estimate visit typically within 3–7 days for most of our service area. The estimate is written, detailed, and yours to keep — no pressure to proceed.

We serve Warrenton, MO and a 50-mile radius across central Missouri. This includes Warren County (our primary territory), St. Charles County (Wentzville, Foristell), Lincoln County (Troy), Montgomery County (Jonesburg), Franklin County (Washington), and parts of Audrain County. If you're unsure whether your address is in our coverage zone, contact us — we'll confirm.

We provide fixed-price written estimates for clearly defined scopes — full roof replacements, siding projects, window installations, etc. For larger renovation projects with unknown conditions (like full interior remodels or projects involving demo), we use a detailed allowance-based contract that spells out what's included, what's a variable, and what triggers a change order. You will always know your exposure before we start.

Yes. Most projects require a deposit of 30–50% upon contract signing to cover materials and scheduling. The remaining balance is due upon project completion and your walkthrough sign-off. We do not ask for full payment upfront — if a contractor demands full payment before starting any work, that is a warning sign.

A change order is issued any time the project scope changes from what was originally estimated. Common triggers include hidden rot or structural damage discovered during demo, homeowner-requested material upgrades, permit-required code upgrades not visible before opening walls, or changes to the original project plan. We never do additional work without a signed change order — you will always know the cost before we proceed.

Yes, every project starts with a written contract that outlines scope of work, materials, timeline, payment schedule, warranty terms, and change-order process. We do not do verbal-only agreements. If a contractor wants to start without a written contract, that's a significant risk for you as a homeowner.

Yes. As a licensed Missouri general contractor, A&S Contracting Services handles the full permit process — application, scheduling of inspections, and final approval. In Warren County, most structural projects (roofing, framing, windows, electrical, plumbing) require a permit. We manage this so you don't have to, and we will not start permit-required work without the permit in hand.

In Warren County, permits are typically required for: new roofing on structures over a certain size, structural framing changes, additions, electrical upgrades, plumbing changes, HVAC installation, window replacement in load-bearing structures, and any work visible from the street. Minor repairs, painting, and cosmetic work generally do not require permits. We assess this during the estimate and let you know what's required before the project starts.

Yes. As a Missouri-licensed GC, we can pull permits in any municipality within our 50-mile service area, including Wentzville (St. Charles County), Troy (Lincoln County), and Washington (Franklin County). Municipal requirements vary, and we navigate those differences for each project.

A standard residential roof replacement in the Warrenton area takes 1–2 days for most homes. Larger roofs, steep pitches, or complex roofline geometry may extend that to 3–4 days. Material lead times depend on current supply — we order materials as soon as the contract is signed so there's no unnecessary delay between approval and start.

A typical full siding replacement on a Warrenton-area home takes 3–7 days depending on square footage, trim complexity, and whether the job includes soffit, fascia, and window wrapping. We sequence work to minimize the amount of time your home is open to weather.

Yes. After a significant weather event in Warren County or surrounding areas, we prioritize storm damage assessments. We can typically schedule an on-site visit within 1–3 days of a storm and move quickly to tarping or emergency repairs to prevent further water infiltration. Document the damage with photos as soon as it's safe to do so, and contact us immediately — insurance adjusters often move faster when a licensed contractor has already assessed and documented the damage.

The optimal window for exterior work in central Missouri is April through October, when temperatures stay above freezing consistently and roofing materials (shingles, caulks, adhesives) cure properly. However, we work year-round — winter projects are feasible for many exterior repairs with the right material selection and conditions. Interior work (drywall, flooring, painting) can proceed any time of year regardless of temperature.

Yes. That is our core capability as a general contractor. We self-perform roofing, siding, gutters, soffit, fascia, windows, doors, drywall, and interior finish work. A full home renovation — from new roof to finished interior — can be managed entirely under one A&S contract, one timeline, and one crew. This eliminates the scheduling conflicts and trade gaps that plague multi-contractor renovation projects.

Yes. A&S Contracting Services accepts light commercial projects including small office buildings, retail spaces, warehouses, and mixed-use properties within our service area. Contact us with your project details for a scope review — we'll confirm whether it fits our current capacity and capabilities before scheduling an estimate.

Yes. We assist homeowners through the insurance claim process for storm-related damage, including hail damage to roofing and siding, wind damage to fascia and gutters, and water infiltration from failed roofing systems. We provide documented assessments that help insurance adjusters determine the full scope of damage. We do not charge for storm assessments — the cost of the assessment is built into the project if you choose to move forward.
