I got called out to a 1923 house on Cabarrus Ave last spring because the homeowner's kitchen floor had developed a noticeable dip between the sink and the refrigerator. She thought it was cosmetic. Her contractor thought it was a subfloor issue. When I dropped under the house I found a girder that had lost cross-section along a four-foot run directly under the kitchen, a pier that had settled almost two inches, and 40-year-old cedar shims that came apart under a probe. The house had been carrying that load through the two adjacent piers for probably fifteen years and one of them was starting to show hairline cracking in the mortar. Two years from that call and it would have been a structural engineer scope, not a repair scope. She got lucky. She noticed the dip.
Crawlspace repair in Concord is a broader category than most homeowners realize when they call. It covers pier settlement, girder replacement, joist sistering, subfloor patching, sill plate rot, rim joist repair, and the sequencing of all of it around any moisture work. In this city the split between the pre-World War Two downtown stock and the 1990s-through-2020s suburban belt drives what kind of repair you are looking at. Downtown houses on Union St, Cabarrus Ave, Church St, and Warren C Coleman Blvd almost universally have pier settlement issues, sometimes rotted sill plates from a hundred years of groundwater contact, and occasionally rotted joists at the perimeter where the sill has failed. Subdivision houses in Christenbury, Moss Creek, Cox Mill, and Robinson Church rarely have pier problems — the poured footings hold — but they do have rim joist rot from decades of vented humidity, HVAC-related subfloor damage where a rusted drain pan finally let go, and the occasional joist that has taken enough sustained moisture to justify sistering.
Cabarrus County structural permitting is where Concord differs meaningfully from Mecklenburg. Any structural repair — new pier footings, girder replacement, sistering joists, subfloor patch that touches framing — needs a Cabarrus County building permit and inspection filed through the county building inspections office in downtown Concord. Inspectors here are stricter than Mecklenburg on pier footing depth. Twelve inches minimum, on undisturbed soil, and they will fail a footing that was poured on fill or that shortcut the depth. We plan for that and we send inspector-quality photos of soil condition and depth before every pour so the inspection is a formality. What follows is what actually breaks under Concord crawls, how we sequence the repair, and what the Cabarrus County process looks like end to end.
Repair sequencing on a downtown Concord house starts with a full pier and girder survey before I write a scope. I go pier by pier with a probe and a straight edge, checking for movement, mortar cracking, shim rot, and girder bearing condition. On a typical 1900s-1930s Union St or Cabarrus Ave house it is normal to find two or three piers that have settled a half-inch to an inch and a half. The girder above compensates by bowing until somebody adds shims. Those shims are usually cedar, usually installed in the 1970s or early 1980s, and they are past their engineered life. Every third or fourth shim stack comes apart under a screwdriver. That is not a repair you defer.
The fix on a settled pier is shore-and-rebuild. We install a Grip-Tite adjustable steel post or a Tiger SmartJack under the girder on either side of the pier to transfer the load off, then we demo the existing pier down to the original footing (if there is one — sometimes the pier is just bearing on grade, in which case we excavate to 12-inch Cabarrus code depth on undisturbed soil). Then we pour a new footing, let it cure, and rebuild the pier with new brick or CMU up to the girder height with shims of solid steel plate rather than cedar. Cabarrus County building permit and inspection required. We send the inspector photos of the excavation before the pour showing soil condition and depth measurement. That inspection has passed on the first visit every time we have followed the photo protocol.
Sistering joists is a separate scope that comes up more on downtown houses than subdivisions. Hand-hewn 2-by-8 or 2-by-10 joists from the 1900s and 1910s are actually oversized compared to nominal modern lumber, but 100 years of intermittent moisture at the sill plate can rot the joist end where it bears on the perimeter. We sister with modern 2-by-8 or 2-by-10 pressure-treated lumber, bolted with 1/2-inch galvanized carriage bolts every 16 inches, extending from the bearing point to a minimum of 4 feet into sound joist. That is a Cabarrus building permit and it inspects fine as long as the bolt pattern and lumber grade match the submitted plan.
Subdivision repair is a completely different sequence. Christenbury, Moss Creek, Cox Mill, and Robinson Church houses from the 1990s and 2000s were built on poured concrete footings that hold. Pier settlement is rare. What we see instead is rim joist rot from decades of vented humidity, subfloor damage where a rusted HVAC drain pan finally let go, and occasional joist damage under a leaking upstairs bathroom that ran for years unnoticed. Rim joist repair is demo of the rotted section, decontamination, sistering or replacement with pressure-treated lumber, and re-insulation with open-cell spray foam. Subfloor patches are cut back to sound wood between joists, sistered with blocking, and patched with tongue-and-groove plywood. Both scopes need a Cabarrus County building permit and both inspect cleanly with normal work.
Structural materials on a Concord repair job are code-plus-a-margin. New pier footings are 20-inch by 20-inch by 12-inch minimum depth on undisturbed soil, poured with 3,500 PSI mix. Cabarrus inspectors will fail a footing that is not to depth or that was poured on fill. Piers rebuild with either standard 8-by-8-by-16 CMU or reclaimed period brick where the historic district review favors matching original material. Shims are solid steel plate, not cedar, not composite. Grip-Tite adjustable steel posts and Tiger SmartJacks are our two workhorses for interim shoring and permanent supplemental support — both are pre-engineered to load ratings that satisfy the Cabarrus County inspector without additional engineering stamps for typical residential loads.
Sistering lumber is pressure-treated Southern Yellow Pine, minimum #2 grade, matching the dimensional depth of the existing joist. Fasteners are 1/2-inch galvanized carriage bolts at 16-inch spacing on a staggered pattern, with structural screws (GRK RSS or Simpson SDS) as a supplemental fastener on the sister-to-sister connection. Girder replacement uses either engineered LVL or steel W-beam depending on span and load — a downtown Union St house with a 14-foot unsupported girder span usually gets a 3-ply 2-by-10 LVL with a mid-span steel post added. Steel beams come in when the header runs a specific bearing wall replacement.
Rim joist repair on subdivision jobs uses pressure-treated 2-by dimensional lumber matching the existing rim, fastened with structural screws to the floor joist ends and sill plate. Post-repair insulation is 3 inches of open-cell spray foam over the sistered rim. Subfloor patches use 3/4-inch tongue-and-groove plywood, glued and screwed to sistered blocking between joists.

Downtown Concord pre-war houses need pier repair and shim replacement on almost every job before any moisture work can happen — the unmortared brick stacks are 100 years old and the 1970s cedar shims are 40 years into a decay cycle they were never engineered for. Cabarrus County inspectors are strict on 12-inch footing depth on undisturbed soil and will fail a shortcut pour, which is a real difference from Mecklenburg practice.

Two obvious tells and one subtle one. Obvious: your interior floor has a visible dip or a spot where furniture legs tilt, or an interior door has started sticking in a specific frame. Subtle: a hairline crack in the mortar between courses on an exterior perimeter chimney or brick veneer that lines up with an interior floor sag. Non-obvious: you go under the crawl and you can see shims stacked between the girder and a pier — that is somebody responding to settlement, and if the shims are cedar and 30 years old they are not carrying the load anymore. If any of that is you, get an inspection. Pier repair caught early is a one-day job. Pier repair caught late becomes a girder-replacement job.
A building permit filed through the Cabarrus County Building Inspections office in downtown Concord. For pier work the permit needs a site sketch showing the pier locations, the proposed footing dimensions and depth, and the intended pier reconstruction method. For sistering or girder replacement the permit needs the affected joist or girder locations, the lumber grade and dimensions of the sister or replacement, and the fastener schedule. Inspection is on the framing before it is covered and Cabarrus inspectors will fail a footing that was not poured to 12-inch depth on undisturbed soil. We handle the permit filing and the inspector coordination as part of the scope.
Structural repair comes first, encapsulation goes last. Every time. The reason is that pier work, sistering, girder replacement, and subfloor patching all generate wood dust, drop debris, and involve tools that will trash a fresh 20-mil liner. We sequence all structural work first, get any inspections passed, then bring the encapsulation crew in behind them for the ground cover, wall termination, and dehumidifier. On a typical Concord job with both scopes we run three to five days of structural work followed by two to three days of encapsulation. Total on site is usually a week to ten days depending on scope.
A 27-year-old subdivision build is at the age where a few specific components start showing wear. The 6-mil ground cover is done. The foil-faced fiberglass batts are usually falling out. The rim joist may have taken enough moisture to warrant inspection. Pier settlement is rare on Cox Mill because the poured footings hold. But the vented crawl has been running high humidity for the entire life of the house and any wood component that has been intermittently wet is worth probing. Get an inspection. If the framing probes solid, all you need is encapsulation. If a rim section or a joist bay has taken enough moisture to have soft spots, we patch that first and encapsulate after.
