Home addition — Lexington County
A large addition framed onto an existing home, with a new covered porch, roof tie-in, and a finished interior built around a fireplace with custom built-ins.
AdditionFraming through finished exterior and interior.

Additions, whole-home remodels, kitchens, baths, decks, siding, flooring and insurance rebuilds for homes in Columbia, Lexington and the surrounding Midlands. You get one written scope, one schedule and one company responsible for all of it.
On a house, "general contractor" describes a role. One company holds the contract, writes the scope, sets the schedule, pulls the permits, runs the trades and is responsible for the finished result. You make decisions. You do not referee carpenters, plumbers, electricians and tile setters who were each hired separately and each blame the trade before them.
That is how we run every job. Some trades are our own crews and some are subcontractors, depending on the trade. Either way, the work is supervised by us and warrantied by us, and you never chase a trade yourself.
The value of a general contractor is sequence. Rough-in has to be finished before insulation, inspections have to pass before walls are closed, and cabinet and tile lead times have to be ordered against the framing schedule. On a single room you can improvise. On an addition or a whole floor, one trade out of order costs weeks. Holding the whole sequence is the job.

Learn moreMost of our year is spent rebuilding houses to an insurance-grade scope. Every line is itemized, every quantity is measured and every change is written down before it is built. When you hire us for a remodel, you get the same discipline applied to a project you chose. You can compare our estimate line by line against anyone else's, because it says what is included and what is not.
We also spend our week opening up Midlands houses built in the fifties, sixties and seventies. We know what tends to be behind the drywall before we price the job: old wiring, failed cast iron, rot at the band board and asbestos flooring under two later floors. We price that possibility honestly, and when we find something, you get photos, options and a written change order before anyone builds it.
And because we do restoration, a remodel that turns up an old leak or a storm-damaged section does not stall while you find a second company. Roofing and gutters go through our sister company, Beaver Roofing & Gutters, out of the same shop on Leaphart Road.

Which office permits your project depends on the parcel, not the mailing address. We confirm it before the schedule is set, pull the permit, and book every inspection.
Structural work such as additions, removed walls and second-story work is engineered and permitted, not improvised. Permit offices in the Midlands generally want stamped plans for anything structural.
Anthony John Construction holds SC Residential Builder License #48882 (Say Jay Inc.), issued by the South Carolina Residential Builders Commission. We are an IICRC Certified Firm for restoration work and are licensed and insured in South Carolina. You can look up the license number on the SC LLR website before you sign anything, and we recommend doing that with any contractor.
We look at the structure, the panel, the plumbing and how the house was built before we talk about finishes, and tell you what is realistic for your budget.
A line-by-line scope and price before demolition, with allowances shown as allowances, so you know which numbers can still move.
Engineering where spans or loads require it, the permit pulled, and long-lead items ordered against the schedule.
Demolition through finishes in the right order, inspections passed before cover-up, then a punch-list walkthrough with you.
Tell us what you want to change. We will walk it, write it down and give you a price you can hold us to.
Yes. Where your city or county requires a permit for structural, electrical or plumbing work, we pull it and schedule the inspections. We confirm which office covers your address first.
Both, depending on the trade. Either way the work is supervised by us and warrantied by us — you never have to chase a trade yourself.
Yes. For most projects we handle layout and selections with you, and for heavily architectural work we work comfortably from someone else's plans.
Roofing and gutters are handled by our sister company, Beaver Roofing & Gutters, out of the same shop on Leaphart Road, so a project that needs a roof tie-in stays coordinated.
Yes. We put the house back to its pre-loss condition under the claim and quote any upgrades separately, so you can see exactly what is the claim and what is yours.
Send the room, the rough idea and a timeline if you have one. We will call you back to set up a measure.
