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.

Last November I got called to a 1935 Cannon Mills company house on Cannon Blvd — one of the mill houses that sits on the east side of the old mill village near the historic Cannon Village retail area. The homeowner had noticed the interior door frames were racking (doors that used to close were now sticking) and the hardwood floor in the front room had a visible dip you could see from the entry. I dropped into the 20-inch clearance crawl and the story was legible in about 15 minutes. The main girder running north-south through the center of the house had settled about an inch and a half at the middle third of its span. Two of the interior brick piers supporting the girder had sunk — one because its pad had cracked in half from 90 years of Piedmont clay expansion and contraction, the other because the pier itself had walked off the pad and was now sitting on the edge instead of centered on the bearing.
Structural support work on Kannapolis housing splits by era in the same way everything else does. On the 1930s Cannon Mills mill village stock — thousands of nearly identical one-story frame houses on brick pier foundations across West Kannapolis, East Kannapolis, and the blocks around Main St and S Ridge Ave — the standard support scope is pier reset, pier rebuild on new footings, girder sistering or replacement, joist sistering at bearings, and occasionally full new interior pier lines added where the original spacing has proven inadequate. Tiger Foundation SmartJacks are the workhorse for both shoring and permanent support installation in the tight 22-inch clearances. Grip-Tite adjustable steel posts are the alternate where the load or geometry calls for them.
On the 2000s and 2010s subdivisions — Village Park off Main St extension, Forest Park, and the newer builds along Trinity Church Rd and Kannapolis Pkwy — the pier and girder are almost always fine because they were built to the 2000s building code with proper block perimeter and interior pier spacing. Structural work on those houses is usually rim joist rot from failed builder vapor management, sole plate replacement, and occasional joist repair where builder-plumbing leaks went unnoticed for years. Different scope entirely. Cabarrus County (Concord office) handles most Kannapolis structural repair permits, Rowan County (Salisbury) handles the north-side parcels that cross the county line. Free on-site inspection anywhere in Kannapolis, Concord, China Grove, Landis, and the surrounding Cabarrus and southern Rowan area.
The process on a Cannon Mills structural support job starts with diagnostic work under the house. When a homeowner reports racking door frames or a visible floor dip, the obvious explanation is pier settlement — but sometimes the pier is intact and the girder above has lost cross-section from decades of humidity, and jacking the pier will do nothing because the girder cannot transfer the load. My first hour under the house is probe testing (screwdriver at every pier bearing and every girder pier junction), measurement (4-foot level on every pier, string line across the girder to identify settlement pattern), and photography (every pier condition, every pad, every girder bearing).
Once the failure mode is clear, the repair sequence matters. If the pier is intact and the pad is sound but the pier has settled slightly, we shore with a Tiger SmartJack under the adjacent girder section to relieve the load, jack the pier back to plumb, add cedar shim packs to fill the gap between pier and girder, and re-load the pier gradually. Single-pier reset without pad replacement is a same-day job and does not require a permit in either Cabarrus or Rowan County. If the pier itself has lost brick or the pad has cracked, we shore, demo the failed pier, excavate to undisturbed soil, pour a new 12-inch-depth concrete footing (Cabarrus inspectors will fail a footing that is not on undisturbed soil so we excavate past any loose fill), and rebuild the pier with mortared brick or 8-inch CMU to the original girder bearing height. That is 2 to 3 days and pulls a Cabarrus or Rowan County building permit.
Girder work is bigger scope. Sistering a girder that has lost cross-section but is still functional means adding a matched dimensional lumber or LVL member alongside the existing girder, mechanically fastened on a specified pattern to transfer load into the new member. Full girder replacement means shoring the joists above with a row of adjustable steel posts on 8-foot centers, demoing the failed girder, dropping in a new engineered beam, and transferring load back to the perimeter one pier at a time. 3 to 5 days for a Cannon house girder replacement. HVAC ductwork usually has to be temporarily moved to work around the girder line, which we coordinate with an HVAC contractor when the scope calls for it.
Rim joist and sole plate repair on the Village Park and Forest Park subdivisions is a completely different sequence. On those houses the pier and girder are fine — what has failed is the rim joist and sometimes the sole plate where 15 to 20 years of failed builder vapor management has rotted the bottom of the rim from the inside. Repair means demoing the failed wood, treating any residual mold with a borate fungicide, sistering or replacing the sole plate and rim section, and re-insulating with open-cell spray foam. If the failure has climbed into the joist ends, sister those joists back to sound wood. This scope nearly always precedes a full encapsulation — otherwise the same moisture that rotted the wood the first time will rot the new wood too.
Tiger Foundation SmartJacks are our primary support element for both temporary shoring during repair work and permanent supplemental supports where an original pier line has proven inadequate. SmartJacks have adjustable-height threaded rod construction rated to typical residential girder loads (typically 24,000 pounds per jack), fit within tight 22-inch Cannon house clearances better than most alternatives, and can be installed on a new 24-inch by 24-inch by 8-inch concrete footing on undisturbed soil. Grip-Tite adjustable steel posts are the alternate for taller crawls (Village Park and Forest Park 38 to 42-inch clearances) or where the load calls for a different profile.
New footing spec is 3,000 PSI concrete poured to 12-inch minimum depth per NC Res Code, on undisturbed soil past any loose fill. Cabarrus County and Rowan County inspectors both verify footing depth and bearing on undisturbed soil during inspection — Cabarrus is stricter on the depth verification, Rowan is more flexible on scheduling. Footing dimensions vary with load: 16 by 16 for interior single-pier locations, 20 by 20 for perimeter piers carrying combined loads, 24 by 24 for concentrated point loads under new supplemental posts.
Girder sistering uses matched dimensional lumber (2x10 or 2x12) or engineered LVL (typically 1.75 by 9.5-inch or 1.75 by 11.875-inch depending on span and load). Fasteners are Simpson SDS structural screws on a 12-inch pattern staggered — not lag bolts, which do not hold their preload as reliably under seasonal humidity cycles in a Kannapolis crawl. Joist sistering uses matched dimensional lumber with the same Simpson fastener spec. Pressure-treated bottom protection on any bearing surface that contacts masonry.
Rim joist and sole plate repair on the newer subdivision houses uses pressure-treated 2x lumber for the sole plate replacement, dimensional lumber for the rim joist replacement (matched to original size), Simpson connectors at any joist-to-rim junction that needs mechanical reinforcement, and open-cell Icynene spray foam at 3 inches for the re-insulation. All treated with a borate fungicide before installation to prevent recolonization by the fungi that rotted the original.

Structural support scope on the 1930s Cannon Mills mill village housing is dominated by pier resets, pier rebuilds, and girder work driven by 90 years of Piedmont clay movement on undersized original footings — on the 2000s Village Park and Forest Park subdivisions structural work is almost entirely rim joist and sole plate repairs from failed builder moisture management.

Almost always structural. Doors racking and visible floor dips are the two most reliable homeowner-observable signs of pier or girder settlement, and on the 1930s Cannon Mills housing they usually mean exactly what they look like. The inspection under the house tells us the specific failure — pier settled off pad, pier pad cracked, girder lost cross-section, joist bearing softened, or some combination. On rare cases it can be subfloor damage from a plumbing leak that mimics settlement, but that shows up in the inspection too. Free inspection to figure out what is going on.
Depends on the scope. Single pier reset or pier rebuild with new footing on the original girder bearing is standard repair — no engineer stamp required in either Cabarrus or Rowan County for a like-for-like restoration to original spec. Adding new supplemental pier lines to a girder that was not originally designed for them, or replacing a girder with a different beam type (going from wood dimensional to engineered LVL), typically triggers engineer stamp requirement so the load path and beam sizing is documented. We coordinate with a structural engineer when the scope calls for it and their fee is a separate line item on the written proposal. On typical Cannon Mills pier work, no engineer needed.
Depends on how much settlement, whether the load has redistributed cleanly to adjacent piers, and whether secondary framing damage is developing. An inch or two of pier settlement in a Cannon house is not immediately dangerous — the load has usually redistributed to the adjacent piers and the framing above is now carrying more than it was designed for but is not on the verge of failure. What worries me is progressive settlement (getting worse each season) and secondary damage (joist bearings softening, girder splitting, subfloor cracking). If you can see the floor slope from above and you have not been under the house recently, get an inspection before the next storm season. Sitting on progressive settlement is how a repair that would have been pier work becomes girder replacement plus subfloor patching.
Less than most homeowners expect. Nearly all Cannon Mills pier and girder work is done from below through the crawl access — nothing is happening inside the house, no interior demo, no interior noise beyond the occasional impact when we are setting a jack. Pier reset and single-pier rebuild is 1 to 3 days and you can live in the house normally. Full girder replacement is 3 to 5 days with intermittent access-level noise during load transfer phases, but again all the work happens under the house. The only scope that gets disruptive is if the structural repair reveals subfloor damage from above that requires cutting patches from the top side, which is uncommon and pre-flagged during the inspection when possible.
