If your floors sag, bounce, or slope, the fix isn't a new floor — it's what's holding it up. We install adjustable steel support jacks on concrete footings, sister rotted joists, and replace failing girders where they've given out.

Structural support work is where the Mint Hill housing split shows up most dramatically. The 1980s and 1990s subdivisions off Matthews-Mint Hill Rd and Lawyers Rd — Wildcat Cove, Ashe Plantation, and the smaller HOA pockets in between — sit on block perimeter foundations with poured pier footings and were built to code well enough that structural issues are uncommon. When we do structural work in a subdivision Mint Hill crawl it is usually a targeted repair: a single sagging joist, a sistered pair to address minor deflection, or an occasional new column with a Tiger SmartJack under a mid-span girder splice that has settled a fraction of an inch. Clean, engineered work with defined scope and a two- or three-day timeline.
The 1960s farmhouse conversions on acreage lots along Wilgrove-Mint Hill Rd, Lawyers Rd east of Downtown Mint Hill, and rural stretches of Fairview Rd are the opposite category and the reason we have a licensed structural engineer we work with on almost every farmhouse job in this town. Unmortared brick pier construction spaced 10 to 14 feet on center with no continuous perimeter foundation, joists sistered over four decades by three different owners with mismatched lumber and drywall screws, girders that have decayed from below because they sat on dirt with no vapor barrier for 50 years, and additions bolted on in the 70s and 90s that were themselves supported by ad-hoc footings on grade instead of below the frost line. Every one of those is a real structural project, not a repair.
Last November on a farmhouse off Wilgrove-Mint Hill Rd I sequenced through the full farmhouse conversion structural playbook. Engineer specified pier shoring and girder replacement. We shimmed two out-of-plumb brick piers with a hydraulic bottle jack and cedar shims. Installed a new pressure-treated 2x10 girder sister with a Grip-Tite adjustable steel post on a poured 24-inch by 24-inch by 12-inch footing. Patched failing subfloor above the softest section. Two weeks of work for a house whose owner had assumed she just needed a vapor barrier and a dehumidifier. The moisture work came later. It always comes later on farmhouse conversions.

Diagnostic protocol on any Mint Hill structural inspection is the same regardless of era. Self-leveling laser across the entire floor system to measure deflection at each joist bay. String line pulled bay to bay for cross-check. Load path mapping from ridge down through walls, girders, columns, and footings to soil. Every column bearing, every girder splice, and every joist end gets probed for rot and crushing with a pinless moisture meter and an awl. Lifting the wrong point makes the problem worse. That protocol does not change between a subdivision crawl and a farmhouse crawl. What changes is what I find.
Subdivision structural work in Wildcat Cove or Ashe Plantation typically follows a simple path. Sagging joists sister full-length with pressure-treated YellaWood 2x8, 2x10, or 2x12 to match original dimension, bolted through with half-inch galvanized carriage bolts on 16-inch staggered centers, structural adhesive between the members. Simpson Strong-Tie SDS or GRK RSS structural screws as an alternate fastener. Where a joist lands on a girder in an original toe-nail connection we back it up with a Simpson AC post-cap or HH hanger so the connection is not relying on 25-year-old 16d nails. New columns on subdivision jobs go on poured concrete footings sized for actual load — 24 by 24 by 12 inches minimum, 6 inches below grade on undisturbed soil, 3,000 PSI mix with a rebar mat. Tiger Foundation SmartJack, Grip-Tite adjustable steel post, or Ellis 2-6 depending on the load rating required and the clearance available.
Farmhouse conversion structural work off Lawyers Rd or Wilgrove-Mint Hill Rd is a completely different sequence and I want to be explicit about it. Step one is always a licensed structural engineer to walk the crawl and specify the fix. Not a contractor with an opinion. An actual engineer with a stamp. The engineer looks at the whole load path — soil, footings, piers, girders, joists, walls, roof — and specifies pier shoring or replacement, girder repair or replacement, joist sistering or cutting-and-scarfing, subfloor patching, and any wall-to-floor connection reinforcement. Step two is the structural work itself, executed to the engineer's spec. Unmortared original brick piers stay in place if they are still plumb and load-bearing — we do not demolish serviceable historic construction, we supplement it with new columns on proper footings sited nearby. Piers that have shifted get shimmed with a hydraulic bottle jack and cedar shims to bring them back to plumb, then locked in with steel bearing plates. Girders that have decayed get replaced with new pressure-treated stock or an engineered LVL where clearance is limited. Rotted joist sections get cut out and replaced with PT lumber scarfed into sound wood on both ends, not sistered over the rot. Step three is verification with the engineer — a walkthrough after structural completion and a signed acceptance before we move to moisture work.
Farmhouse conversion additions from the 70s and 90s often have their own structural issues that are separate from the original 1960s footprint. Additions were frequently supported on shallow pads that sit above the 12-inch frost depth required by NC Res Code, and they move with freeze-thaw cycles. Those additions get new footings poured under the existing pad, sometimes with an interior column shift, and the engineer signs off on the load path from the addition back through to the original structure.
Column specification is by load and clearance. Tiger Foundation SmartJack on taller subdivision crawls in Wildcat Cove or Ashe Plantation where clearance is 36 inches or better and the load rating up to 60,000 pounds is useful. Grip-Tite adjustable steel post in the middle ground — reliable, published load ratings, adjustable head for slow controlled lift. Ellis Manufacturing 2-6 screw jack and Akron Products AP1J in the tighter farmhouse crawls off Lawyers Rd where clearance is 24 to 30 inches and a full SmartJack will not fit. All columns have threaded tops for controlled slow-lift and steel bearing plates top and bottom.
Every new column goes on a poured concrete footing sized for actual load, not a default footprint. Minimum 24 by 24 by 12 inches at 3,000 PSI mix with a rebar mat, 6 inches below grade on undisturbed soil. Not on brick piers. Not on paver stacks. Not on dirt pads. Not on old footings of unknown depth or condition. Freeze depth in Mecklenburg is 6 to 8 inches, code requires footings at 12 minimum, and every winter I get calls from farmhouse owners whose interior columns moved because a previous contractor rested them on grade or on shallow pads.
Sistered joist stock is YellaWood ground-contact pressure-treated southern yellow pine, always. 2x8, 2x10, or 2x12 to match original dimension. LVL — Boise Cascade VersaLam or Weyerhaeuser Microllam — spec'd by the engineer where clearance limits joist depth or where the span requires a stiffer member. Fasteners are Simpson Strong-Tie SDS structural screws or GRK RSS at 6-inch staggered centers, or half-inch galvanized carriage bolts through-bolted with washers on both sides for full sisters. PL Premium or Loctite PL Structural adhesive between members. Never drywall screws, deck screws, or 16d nails on structural work.
Connection hardware is Simpson Strong-Tie throughout. AC post-caps at every column-to-girder connection. LU or LUS joist hangers where original toe-nail connections need reinforcement. HH heavy hangers on any larger member. HDU hold-downs on any wall-to-floor connection the engineer specifies. Corrosion protection is ZMAX galvanized on any hardware in a farmhouse crawl where moisture history has been high, and stainless where the engineer requires it. Girder replacements are pressure-treated 2x10 or 2x12 built up as a triple or engineered LVL per engineer spec, resting on the new columns via steel bearing plates.

Mint Hill structural work is the trade where the town's two-housing-era split is most extreme — light targeted subdivision fixes versus multi-week structural rebuilds on 1960s farmhouse conversions with unmortared brick piers, decades of amateur sistering, and no continuous perimeter foundation. Engineer involvement is standard on farmhouse jobs, rare on subdivision jobs.

Yes, and I will tell you that on the inspection before we do anything else. If the piers are unmortared brick stacks that have been shifting for decades, if the girders show any visible sagging or decay, or if you have soft spots in the floor above the crawl, the honest answer is a licensed structural engineer needs to specify the repair before we quote. The engineer costs a few hundred dollars up front and saves you from paying us to do work that has to be redone. On subdivision jobs in Wildcat Cove or Ashe Plantation where a single joist needs sistering, engineer involvement is usually not necessary — that is production carpentry. But on farmhouse conversions, engineer first, always.
Depends on the cause. Bounce with no visible damage in a 90s subdivision crawl is often just the original joist sizing being marginal for the span. Fix is a sister with a stiffer member or an intermediate column on a proper footing to shorten the effective span. Bounce with no visible damage in a 1960s farmhouse conversion off Lawyers Rd is more often the piers moving under load, which is a structural investigation with engineer involvement. We measure deflection with a laser level bay by bay and probe suspect connections before we quote. Same fixed written scope.
We can, but on most farmhouse conversions we do not remove serviceable original piers. If a pier is still plumb and load-bearing, we leave it and supplement with new columns on proper footings nearby. If a pier has shifted or spalled, we shim it back to plumb with a hydraulic bottle jack and cedar shims and lock it in with steel bearing plates, or we transfer the load to a new column on a poured footing and leave the pier in place non-structural. Wholesale pier replacement is expensive, disruptive, and rarely necessary. The engineer specifies which piers stay, which get shimmed, and which get supplemented.
Depends on scope but typical Mint Hill farmhouse conversion structural work runs one to two weeks from engineer sign-off to structural completion. Engineer inspection is a day. Structural work sequence — pier shoring, girder replacement, joist sistering, subfloor patch — is typically 5 to 10 working days depending on how many bays are affected. Then engineer verification walk. Then wildlife remediation if applicable. Only then does moisture work start. Total from first inspection to encapsulation completion on a real farmhouse project is often 4 to 6 weeks. Not fast, but done right the first time.
