Commercial Remodeling FAQ
Quick reference on schedules, permits, after-hours work, and how we handle changes. Don't see your question? Reach out for a free consultation.
Most of the questions we get before a commercial project starts are about the same handful of things: how long the work will take, whether it can happen without shutting the business down, who pulls the permits, and what happens when something changes mid-job. The answers below are the same ones we give on a walkthrough.
Core Commercial Construction handles office renovations, retail and tenant buildouts, industrial and warehouse upgrades, commercial coatings, EIFS installation and repair, and commercial caulking across central Missouri. Because we self-perform a large share of that work, schedules and answers come from the people actually running the site rather than from a broker passing questions down a chain.
How long do commercial remodels take?
Timelines depend on scope, permitting, and material lead times. A small tenant improvement may run 3–6 weeks, mid-size office or retail buildouts typically take 8–16 weeks, and larger industrial or shell-and-core projects can run several months. After the free consultation we provide a realistic schedule with key milestones before any work begins.
Can work be completed after business hours?
Yes. We regularly schedule night, weekend, and phased work for occupied offices, retail tenants on landlord turnover dates, and active distribution facilities. We coordinate access, dust control, and life-safety so your team or customers aren't disrupted.
Do you handle permits?
Yes — we pull all required building, mechanical, electrical, and plumbing permits and coordinate inspections through closeout. If your project needs stamped drawings, we work with licensed design partners or your architect of record.
Do you offer design-build services?
Yes. For projects without an existing architect we can run a design-build process: programming, drawings, engineering, pricing, and construction under one accountable contract. This typically shortens the schedule and removes the friction between design intent and field execution.
What project sizes do you accept?
We take on commercial work from small finish-and-coatings packages through full-building remodels and ground-up shell-and-core. If your project falls outside our wheelhouse we'll tell you up front and, where possible, refer you to a trusted partner.
How do change orders work?
Change orders are documented in writing before the work proceeds. We provide a clear scope, price, and schedule impact so you can approve, modify, or decline — no surprise charges at billing. Field conditions, owner-directed scope changes, and code-driven changes are tracked the same way.
Do you work in occupied buildings?
Most of our projects are in buildings that stay open. We phase the work area by area, build temporary partitions and dust barriers, keep exits and life-safety paths clear, protect finished floors and adjacent tenant spaces, and clean daily. Loud demolition, core drilling, and anything that affects shared systems is scheduled when the building is empty.
What areas do you serve?
We are based in Columbia, Missouri and work throughout central Missouri, including Jefferson City, Boonville, Fulton, Moberly, Ashland, and the surrounding counties. For larger or multi-site programs we travel further — if you have several properties to cover, tell us where they are and we will tell you honestly whether we can staff them well.
Are you licensed, bonded, and insured?
Yes. Core Commercial Construction is bonded and insured, and our crews work under OSHA-compliant safety practices. We provide certificates of insurance, bonding information, and any additional-insured endorsements your lease or lender requires before mobilizing.
How do you handle estimates and budgeting?
The initial consultation and estimate are free. We walk the space, document existing conditions, and return a written scope with line-item pricing so you can see what each part of the project costs. If the number has to come down, we show you which scopes to defer or simplify instead of quietly reducing quality.
Can you work from our architect's drawings, or do you need to provide them?
Either way works. If you already have a design team, we build to their documents and coordinate submittals, RFIs, and inspections with them. If you do not, we can run the project design-build with licensed design partners so drawings, engineering, pricing, and construction all sit under one contract.
What happens at the end of a project?
We walk the space with you and build a punch list, correct the items on it, complete final inspections, and hand over closeout documentation — warranties, product data, and finish and color information for your maintenance records. If something shows up after we leave, call us; we come back.
