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 in Huntersville crawlspaces is a scope I take seriously and I want to be clear that not every homeowner who calls actually needs it. About half the 'my floor is bouncy' or 'I have a crack in my drywall' calls I get out here turn out to be moisture-driven issues that resolve with encapsulation and dehumidification, not structural interventions. The other half are real — deflected girders, rotated interior piers, rotted rim joist, brick piers that have moved or lost mortar, and settled interior footings on the older pre-boom Old Statesville Rd farmhouse stock. Telling them apart requires a real inspection with a level, a plumb bob, a moisture meter, and a screwdriver, not a walk-through with a flashlight and a sales pitch.
Last summer I did a full structural scope on a 1997 Wynfield colonial off Gilead Rd. Homeowner had noticed the master bedroom floor was noticeably bouncy near the center of the room, doors on the second floor were sticking, and there was fresh drywall cracking above the kitchen doorway. When I dropped in I found a main girder deflecting about three-quarters of an inch over a 14-foot span, one interior pier that had rotated maybe four degrees off vertical, and a rim joist section on the shore-facing wall that was spongy across about eight feet where builder fiberglass had held moisture against the wood for two decades. Scope was seven working days: temporary shoring with hydraulic bottle jacks and cribbing, demo and rebuild of the rotated pier on a new poured footing, Grip-Tite adjustable steel post replacing the old lally column, sistered pressure-treated girder repair with Simpson Strong-Tie structural connectors, and rim joist demo, decontamination, and rebuild in pressure-treated framing. Mecklenburg permit pulled and inspected on every element. After the work, the girder came back to level over three staged sessions across two days, the drywall cracks did not open further, and the master bedroom floor stopped bouncing.
Structural work is where the Huntersville housing boom era shows its age. The 1994-2010 Skybrook, Birkdale, and Wynfield stock is now hitting the 15-to-30-year mark where builder shortcuts on rim joist insulation, undersized foundation vents, and hasty exterior grading are showing up as structural damage rather than just cosmetic moisture issues.

The Huntersville structural inspection is a real assessment with proper tools. I bring a 4-foot level, a plumb bob, a laser level for longer spans, a moisture meter, a thermal camera, and a screwdriver. I level-check every girder and interior pier against the perimeter foundation. I plumb-check every interior pier and lally column against vertical. I probe every rim joist bay and every sill plate junction with the screwdriver — soft spots mean rot and get mapped for repair scope. I moisture-meter the joists, girders, and subfloor at multiple points to identify where active decay conditions exist versus where staining is historical. I photograph everything and I write up the scope with deflection measurements, moisture readings, and photos of every affected element.
Sequencing for structural work is critical. Step one is always temporary shoring under any deflected or damaged element before any demo. Hydraulic bottle jacks with wide bearing plates and cribbing, staged carefully so nothing gets shocked. Step two is address any active water source that is contributing to the ongoing decay — exterior grading, downspouts, drainage — because rebuilding a rotted girder while the water source that rotted it is still active is throwing money away. Step three is the structural intervention itself: sistered pressure-treated framing on rotted joists, girder end replacement, rim joist demo and rebuild, brick pier rebuild or replacement with new poured footings and adjustable steel posts. Every intervention pulls a Mecklenburg building permit — CityInspect.charlottenc.gov — and the inspection is real. County cares specifically about footing depth (12 inches minimum on undisturbed soil) and structural connector spec compliance. They will fail you if the pour is on fill or the connector spec is wrong.
Step four is dial the correction back to level slowly. On the Wynfield job in the intro, we lifted the girder in three staged sessions across two days, no more than a quarter-inch per session, checking the drywall and tile upstairs between sessions. That staging is not optional — trying to lift a settled girder back to level in a single afternoon cracks finish carpentry upstairs on any Skybrook, Birkdale, or Wynfield house with competent finish work. Step five is decontamination of any surfaces that had biological growth from the wet history. Only after all of that does the crawl get ready for encapsulation and dehumidification as a separate final scope. If a contractor tells you they can do structural repair and encapsulation in a single three-day window on a house with real structural damage, they are cutting corners on the structural side. It is a phased project by definition.
Grip-Tite adjustable steel posts are my default for interior pier replacement and girder lift work — fine-thread adjustment allows precise staged lifting over multiple sessions without shocking finish upstairs. Tiger SmartJack is the alternate when the ceiling height forces a shorter post or the soil condition demands a wider bearing plate. New footings are poured concrete at 12-inch depth minimum on undisturbed soil per Mecklenburg residential code, formed with 16-inch by 16-inch or larger square forms depending on load calculations. Simpson Strong-Tie structural connectors on every framing junction — LSTA straps for tension, SDS or SDWS structural screws for shear, appropriate hangers on any joist replacement. Pressure-treated southern yellow pine for all sistered framing, girder repair, and rim joist rebuild — dimensional lumber matched to the existing framing depth.
For rim joist repair on the 20-year-old Skybrook and Birkdale housing stock, standard scope is demo of the affected section, decontamination with fungicidal treatment, sistered pressure-treated dimensional lumber matching existing framing depth, fastened with Simpson SDWS structural screws through the sistered plate into the existing sound framing on both sides of the demo cut. Where the rim joist is beyond sistering, full replacement of the affected span with new pressure-treated framing and Simpson Strong-Tie connectors to the mudsill and rim joist ends. For brick pier rebuild on the pre-1990 Old Statesville Rd farmhouse stock, we salvage sound brick where possible and rebuild with Type S mortar on a new poured footing at 12-inch depth. For block wall crack repair driven by expansive clay movement on shore-facing walls, polyurethane resin injection through drilled and ported packers — the polyurethane cures flexible and moves with the next seasonal expansion cycle instead of cracking again like rigid epoxy would. HMI TerraThane 24024 polyurethane foam injection is my spec for interior slab lift on the small percentage of Huntersville homes with partial-crawl-partial-slab construction.
Yes — Huntersville is a regular structural support route. Free on-site inspection anywhere in Huntersville, fixed written quote before we touch anything.
Huntersville structural work is concentrated in the 1994-2010 Lake Norman boom housing stock now hitting the 20-to-30-year mark where builder shortcuts on rim joist insulation and undersized vents are showing up as rim joist rot, deflected girders, and pier movement on shore-facing walls. Lake-proximity homes off McCoy Rd and Beatties Ford Rd have compressed timelines because seasonal water table pressure accelerates the failure sequence.

One quick way to sort it out. Stand in the bouncy spot with a helper. Have the helper drop into the crawl below and look at what is directly under the bouncy area. If a joist or girder is visibly deflected under load when you shift weight on it, you have a structural problem — the framing member is fatigued or has lost cross-section from decay. If nothing moves visibly and the joists look solid, it is often a subfloor problem — a squeaky nail, a delaminated subfloor panel, or a subfloor bay that never got proper support blocking. The former is a real repair scope. The latter is often a much smaller fix. I check both on the inspection with a moisture meter, level, and screwdriver.
Slowly and in stages. On the Wynfield job I described in the intro, we dialed a three-quarter-inch settled girder back to level in three sessions across two days, no more than a quarter-inch of lift per session, with the drywall and tile upstairs visually checked between each session. No new cracks. Trying to do the full lift in one afternoon would have cracked finish carpentry on the second floor for sure. This staging is not optional on any Skybrook, Birkdale, or Wynfield house with competent finish work. The homeowners in this town care about their houses and we do not shortcut the process to save a half-day of scheduling.
Depends on the extent of the rot and the structural spec required. On the older 15-to-20-year-old Skybrook and Birkdale stock where the rim joist is spongy across 6 to 12 feet from years of trapped moisture behind builder fiberglass, sistered pressure-treated framing on both sides of the affected section with Simpson SDWS structural screws is often the appropriate scope — you preserve the load path and reinforce the compromised area. On rim joists that are beyond sistering (through-and-through decay, missing sections, or fully rotten), full demo and replacement of the affected span with new pressure-treated framing and Simpson Strong-Tie connectors to the mudsill is required. Every rim joist gets probed at multiple points on inspection and the scope determined by the actual condition, not a boilerplate default.
No, and I would not do it without one anyway. Any structural repair — sistered joists, girder replacement, rim joist rebuild, adjustable post installation on a new footing, brick pier rebuild — pulls a Mecklenburg building permit filed through CityInspect.charlottenc.gov and the inspection is real. The county cares specifically about footing depth (12 inches minimum on undisturbed soil), structural connector spec compliance (Simpson Strong-Tie or equivalent), and pressure-treated lumber grade. They will fail you if the pour is on fill or the connector is wrong. Any contractor who tells you they can skip the permit for structural work is exposing you to permit-violation issues at resale and voiding any material or workmanship warranty. Permits are cheap. Do not skip them.
