Crawl Space Jack Posts Across Nebraska, Iowa, Kansas, and Missouri

A jack post on an existing or new concrete footing runs $300-$600 per post installed. A jack post requiring a new helical pier base. Needed where soil is loose, settling, or expansive. Runs $1,800-$3,000 per location because the helical pier itself accounts for most of the cost. Written estimate after on-site inspection reflects your scope.

Epp Foundation Repair carries a lifetime warranty on the jack post installation. Fastener integrity, bearing surface, and crew execution. Helical pier bases (when required) carry a lifetime warranty from Epp on top of the manufacturer warranty. Warranty is transferable to subsequent homeowners and documented at completion.

When a crawl space post fails. Rotted from chronic moisture, settled from soil movement, or buckled from overload. The beam above drops at that point. Floor sag, interior wall cracks, and door binding follow within months. The repair window keeps narrowing: a single $500 jack post installation today becomes a $4,000 beam sister-and-post job in 18 months once the beam itself has cracked or rotted from the prolonged sag, and a $12,000 carrier replacement if the failure is at a carrier beam location.

Steel adjustable posts win on two points: install speed and future adjustability. A wood post needs to be cut to exact length and sits permanently at that length. Any future settlement requires demolition and re-cutting. A steel adjustable post threads up or down in fine increments, so future micro-settlement (which is normal across decades) can be corrected in 20 minutes without demolishing anything. Steel is also immune to the rot that destroys wood posts in chronically wet Nebraska and Iowa crawl spaces.

No, and this is where Epp Foundation Repair turns down work other contractors take. A jack post supports the floor system above (beams and joists); it does nothing for a sinking exterior foundation wall. If the foundation itself is sinking. Exterior wall cracks, doors out of square at the foundation level, settled corners. The right repair is foundation piering (helical or push piers), not crawl space jacks. Epp does both jobs but won't sell the wrong one.

Epp Foundation Repair handles the structural work. Installing the replacement post on solid bearing. For the moisture source (chronic wet crawl, plumbing leak, exterior grading issue) and any active pest activity, Epp refers homeowners to specialists. Some moisture sources are within Epp's scope. Sump pumps, drain tile, vapor barriers, and Epp coordinates those repairs on the same job. Termite treatment and HVAC duct rework are not in Epp's scope; we make the referral.
