San Antonio Foundation Repair provides pier-and-beam repair for homes that sit above the ground rather than on a concrete slab. It is one of seven foundation services we offer across San Antonio and surrounding Bexar, Guadalupe, and Comal County communities. The structure rests on a grid of piers. Wood girders span between those piers, subfloor joists span between the girders, and the sill plate carries the wall framing. The space underneath is the crawlspace, and it is both the reason these foundations are repairable in a way slabs are not and the reason they need a different kind of attention. These homes behave differently under the same soil conditions that drive foundation repair work throughout San Antonio [/ →](/) , which is why the repair methods diverge from slab work. The advantage is access. Every structural member is reachable. A rotted beam end can be replaced, a weakened joist can be sistered, a settled pier can be rebuilt. The disadvantage is that wood is a material that decays, and a crawlspace is a humid, dark, ground-contact environment. In San Antonio, the expansive Houston Black clay common across Bexar County holds moisture against footings and supports Formosan subterranean termite activity that accelerates wood damage. Over decades, that combination does work on the structure whether or not the soil beneath ever moves. ## Which San Antonio Homes Sit on Piers and Beams? In the San Antonio area, pier-and-beam construction dominates housing built before roughly 1960. Alamo Heights, Monte Vista, King William, Dignowity Hill, Tobin Hill, Government Hill, the older parts of Universal City and Schertz, and historic New Braunfels and Seguin are where you find it. Many are Craftsman-style bungalows and historic cottages that predate slab-on-grade construction in Bexar County. Some homes have an original raised structure with a later slab-on-grade addition, which creates a junction between two foundation types that respond differently to the same conditions. ## What the Crawlspace Evaluation Examines The evaluation has two halves. Above the floor, we take interior beam elevation readings across the plan, check door and window operation, and note cracking at walls and ceilings. Below the floor, we go into the crawlspace and document what is actually there. In the crawlspace we look at: - **Piers and footings.** Pier settlement, cracked or crumbling masonry, undersized footings, and pier footing sizing relative to the load above. - **Girders and beams.** Rotted or crushed bearing ends, splitting, sagging between supports, and whether a pad and block arrangement is still doing its job. - **Subfloor joists.** Sagging, splitting, notching for plumbing runs, termite-damaged framing, and fungal decay near the perimeter. - **The sill plate.** Its condition where it bears, since this is a common decay point. - **Ground conditions.** Standing water, damp soil, absent or torn vapor barrier, evidence of drainage running under the house, and crawlspace clearance for the work. - **Structural support connections.** Whether the framing is actually tied together where it should be. Findings are recorded by location so the scope points to specific components rather than describing a general condition. ## Repair Methods and What Each One Is For ### Beam shimming Where a girder sits low over a pier that is itself stable, shims restore contact and correct the local elevation. This is the lightest correction available and it works well when the support underneath has not moved. Shimming a beam that sits over a settled pier just postpones the real repair, which is why the findings distinguish between the two. ### Sistering joists A new joist fastened alongside a compromised one restores load-carrying capacity without removing the original member. It is the standard response to rot at a joist end, termite damage, splitting, or over-notching for plumbing. Sagging and uneven floors that trace to a specific bay usually resolve here. ### Girder replacement When damage runs through the section rather than sitting on the surface, the member is replaced. The load is taken by screw jacks and temporary cribbing, the old girder comes out, and new material, typically treated southern yellow pine sized for the span, goes in. It is more involved than shimming and the scope should say so plainly. ### Pier and footing work Where a pier has settled or its footing was never adequate, new support is built. That may be a concrete sonotube footer poured to depth with a new pier above it, or a rebuilt pad and block assembly. Pier footing sizing follows the load and the bearing conditions at that point, which is why one property can need different footing details in different places. ### Crawlspace moisture management A 6-mil or heavier polyethylene vapor barrier over exposed soil reduces moisture migration into the space. Correcting crawlspace drainage and any grading that channels water under the house addresses the source. Neither reverses existing wood rot, which is repaired separately, but together they stop the same damage recurring. ## How Floor Re-Leveling Works on a Raised Foundation Re-leveling a pier-and-beam home means adjusting support until the floor profile improves toward the target elevation. Screw jacks take the load, adjustments are made in controlled increments, and the structure moves gradually. What it achieves: a noticeably more level floor, doors that operate properly again, and support restored under members that were carrying load they were not sized for. What it does not achieve: a perfectly flat floor matching new construction. Wood structures accumulate decades of adjustment, and the realistic objective is recovery toward level within practical limits. Expect some sheetrock or plaster relief cracking, some trim gaps, and some doors needing adjustment afterwards. These are normal consequences of moving a settled structure, and a proposal that does not mention them is not setting expectations honestly. ## Access, Disruption, and Scheduling Work happens underneath the house, which is unusual among home repairs in that it barely disturbs your living space. There is noise, there are crew members coming and going through the crawl access, and there may be brief periods where a section of floor is being actively jacked. Most households stay in place for the duration. What the San Antonio Foundation Repair crew confirms before the crew date is set: - Crawlspace clearance at the work locations and along the route to them. - The access point and whether it needs enlarging. - Where materials will be staged and where spoil, if any, will go. - Whether plumbing or ductwork in the crawlspace needs temporary disconnection. - Any pets or stored belongings that need relocating. ## What Affects Pier-and-Beam Repair Cost? As of 2026, pier-and-beam pricing in San Antonio tracks component counts and access rather than square footage: | Factor | Why it changes the cost | | --- | --- | | Pier and footing count | Each new footing means excavation, concrete, and cure time | | Beams shimmed versus replaced | Replacement requires temporary support and new material | | Joists sistered | Counted individually; material and access drive the figure | | Girder length involved | Longer runs mean more material and more support points | | Crawlspace clearance | Tight access slows every task and extends the schedule | | Moisture work | Vapor barrier, ventilation changes, or drainage correction | | Restoration | Stated in writing; cosmetic repairs are scope, not assumption | ## When We Recommend Something Else If the elevation readings are flat and the crawlspace is sound, a floor that feels soft in one spot may be a subfloor sheathing issue rather than a structural one, and we will say that. If the crawlspace is saturated and the framing is sound, the honest first step is drainage and moisture management rather than structural repair, because fixing wood that is about to get wet again is not a repair. If a consequential structural conclusion is needed, particularly on a historic property or where a permit requires it, a Texas licensed professional engineer provides an assessment. That is a separate document from our proposal and we will not present ours as a substitute.

Read guide arrow\_forward [Pier-and-Beam vs. Slab: How Repairs Differ →](/guide/pier-and-beam-vs-slab-how-repairs-differ/) Questions we are asked ## Pier & Beam FAQs ### What is a pier-and-beam foundation? expand\_more A pier-and-beam foundation raises the structure above the ground on piers, with wood girders spanning between them and subfloor joists carrying the floor. The space underneath is the crawlspace. It was the standard approach in San Antonio before slab-on-grade construction took over, so it is most common in homes built before the 1960s and in the older central and historic neighborhoods. The sill plate sits on the girders and carries the wall framing above. ### How do I know if my home is pier-and-beam? expand\_more If there is a vented skirt around the perimeter, an access hatch or crawl door, and the floor sits noticeably above grade, it is almost certainly pier-and-beam. Floors that flex slightly underfoot are another indicator, since a wood subfloor behaves differently from concrete. The evaluation confirms it, and the confirmation matters because access, method, and scope are all different from slab work. ### Why do my floors feel bouncy or slope? expand\_more Bounce usually points to the framing: a weakened or undersized subfloor joist, a girder spanning further than it should, or a pier that has settled and is no longer carrying its share. Slope points to differential support, where one pier or footing has moved relative to the others. Both are measurable. Interior beam elevation readings across the plan turn an impression into a profile that shows where the low points actually are. ### What does beam shimming involve? expand\_more Where a beam sits low over a sound pier, a shim of treated hardwood or steel is placed between the pier cap and the beam to restore contact and level. It is a straightforward correction when the pier itself is stable. Where the pier has settled or its footing has failed, shimming alone is not the answer, because the support underneath has moved. We distinguish between the two in the findings rather than shimming everything. ### What is sistering a joist? expand\_more Sistering means fastening a new joist alongside an existing one that has been weakened by rot, termite damage, splitting, or notching for plumbing. The new member carries load alongside the old one, restoring capacity without removing the original. It is common in older homes where full joist replacement would require dismantling more of the floor than the problem justifies. ### When does a girder need replacing rather than repairing? expand\_more When the damage runs through the section rather than sitting at the surface. A girder with rotted ends where it bears on piers, extensive termite tunnelling, or a structural split along the grain is no longer reliably carrying its load. Replacement means temporary support with screw jacks and cribbing, removal, and installation of new material, typically treated southern yellow pine sized for the span. ### Is crawlspace moisture a structural problem? expand\_more It becomes one. Persistent humidity and soil contact support fungal decay in beams, joists, and sill plates, and rotted wood carries less load than sound wood. Crawlspace moisture management, including a vapor barrier over exposed soil, attention to ventilation, and correcting drainage that directs water under the house, addresses the cause. Existing rot still has to be assessed and repaired separately. ### How is a pier-and-beam home re-leveled? expand\_more Screw jacks and temporary cribbing take the load, then support is adjusted in controlled increments through shimming and pier work until the elevation profile improves toward the target. The lift is deliberately gradual. Moving a wood-framed structure quickly transfers stress into plaster, trim, and door frames all at once. Expect some relief cracking and some doors needing adjustment afterwards. ### Will re-leveling crack my walls? expand\_more Some sheetrock or plaster relief and some trim movement is normal and expected. The structure is being moved, and finishes that settled into the old position have to accommodate the new one. On older homes with original plaster it tends to be more visible. We explain the likely effects before work starts, and the written scope states which cosmetic repairs are included and which are not. ### How much crawlspace clearance is needed for pier-and-beam work? expand\_more Workable clearance is generally around eighteen inches or more, though the practical figure depends on where the work sits relative to the access point. Tight crawlspaces are not impossible but they slow the work and that shows up in the schedule and the cost. We confirm clearance and the access route at the evaluation rather than estimating it from the outside. ### What does pier-and-beam repair cost in San Antonio? expand\_more It is driven by component counts and access rather than a per-square-foot figure. The number of piers needing footings, beams needing shimming or replacement, joists needing sistering, the length of girder involved, crawlspace clearance, and any moisture work all move the total. A written quote after an evaluation states the components, locations, materials, and exclusions so you can compare it against another proposal line by line. ### Can pier-and-beam and slab problems occur in the same house? expand\_more Yes, in homes with additions. It is common in older San Antonio neighborhoods to find an original raised structure with a slab-on-grade addition attached. The two foundation types respond differently to the same soil conditions, and the junction between them is often where movement shows first. The evaluation covers both parts and the scope addresses each on its own terms. ### Do you handle crawlspace drainage as part of the work? expand\_more Where drainage is directing water under the house, correcting it belongs in the conversation, because repairing rotted wood without addressing the moisture source is a short-term fix. We explain the options and can include drainage in the scope. We do not attach it to every proposal by default; it belongs there only when the site conditions justify it. ## Related Services fact\_check ### Foundation Evaluation Who attends, what is examined, and what the customer receives from an on-site evaluation.
