Mobile Home Pier & Pad Repair in Wildwood, FL

Pier and pad repair is the work under the work. A manufactured home stands on a few dozen stacks of concrete block, each one sitting on a footing pad pressed into the ground, each one topped by a cap and a pair of hardwood shims that meet the steel I-beam. When a pad sinks, a block cracks, a cap crushes, or a shim stack rots, that pier stops carrying its share and the frame above it drops. We arrange pier resets and full pier rebuilds across Wildwood and Sumter County through licensed, insured Florida mobile home installers. Resets run $75 to $150 per pier and rebuilds $150 to $400, with the survey that counts them free.

Every relevel touches piers. This page is about the ones that need more than a shim.

What a pier is supposed to be

The federal installation standard at 24 CFR 3285.304 lays out the pier in plain terms. Concrete blocks are stacked with their hollow cells vertical and each course turned at right angles to the one below. On top goes a cap, solid concrete or masonry at least four inches nominal or hardwood at least two inches nominal, the same length and width as the pier. Then shims, nominal 4 by 6 by 1 inch, used in pairs and driven in tightly so that they do not occupy more than one inch of vertical height. Hardwood plates no thicker than two inches nominal, or two-inch or four-inch solid block, fill any remaining gap. Under all of it is a footing pad sized to the soil’s bearing capacity.

Florida’s own rule adds the layout. Rule 15C-1.0103 puts piers no more than eight feet apart with the first pier within two feet of either end of the home, requires at least eighteen inches between the finished grade and the bottom of the I-beam, and requires any single-stack block pier over 36 inches tall to be double-tiered and interlocked. Rule 15C-1.0102 says that when the soil bearing capacity is not known, the installer assumes 1,000 pounds per square foot.

That is the whole system, and every part of it fails in a specific way on Sumter County ground.

How piers fail here

The pad sinks. This is the upland failure. Candler sand under the higher ground around Wildwood and Oxford is excessively drained, loose, single-grain sand. A pad that is too small for the load, which is most pads on older homes, presses a few thousand pounds into a footprint the size of a doormat, and every summer storm that pushes water through the sand lets the grains under it settle tighter. The pier goes down a little each year. The pier next to it, under a drier stretch of ground, does not. The beam between them twists.

The pad sinks faster and wetter. This is the flats failure. Sparr fine sand carries a seasonal water table at 23 inches from June through September; Adamsville at 33 inches from June through November. Saturated sand does not compact, it yields. A pad on that ground can drop an inch in a single wet season, and it drops unevenly, so the frame does not just tilt, it warps. Homes near Lake Okahumpka and Lake Deaton along SR 44, and on the low ground toward the Withlacoochee that stayed in flood for weeks after Milton, are the ones we see this on.

The pad moves on clay. The Sumterville-Mabel soils the survey maps with a bouldery subsurface have clay in the profile and a moderate shrink-swell rating. That is rare in Florida. A pad on clay rises a little in a wet summer and drops in a dry winter, and a home on it goes out of level in a different rhythm than a home on sand.

The pad sits on rock, or nearly. Sumter County is sand over the Ocala Limestone, and the survey labels whole map units around Wildwood with a bouldery subsurface. A pad that lands half on a boulder and half on sand rocks. An installer who hit rock while digging a footing and shifted the pier a foot to get around it left the beam supported in the wrong place.

The cap crushes. A cap that is undersized, split, or made of soft scrap lumber crushes under the beam. When the cap goes, the shims go with it, and the beam ends up resting on the top course of block, which was never meant to take a point load without a cap. We find broken top blocks under caps that gave up years ago.

The shims rot or over-stack. Shims are supposed to be hardwood and one inch total. Under an old home in a park off SR 44 we find pine shims that have rotted to sponge, stacks three and four inches tall, and once in a while a paint stirrer. An over-stacked pier is unstable side to side, which matters when a Wind Zone II gust is pushing the home sideways against its anchors.

The block cracks. Freeze is not the problem in Wildwood. Overload is. A pier carrying the load of two failed neighbors cracks its blocks, and a cracked block in a single-stack pier is a pier that is done.

The survey decides reset or rebuild

The free level check that starts every leveling job is also the pier survey. The crew shoots each pier with a water level, but they also put hands on each one: rock the stack, check the cap for crush, count and measure the shims, look at the pad. Each pier gets a verdict.

Reset, $75 to $150. The stack is sound and plumb, the pad has not moved, and the gap to the beam is inside the shim allowance. The pier gets a new cap if needed and fresh hardwood shims driven tight in pairs. This is what most piers on a routine relevel get, and it is what the relevel price includes for the piers it covers.

Rebuild, $150 to $400. The pad has sunk, the blocks have cracked, the stack is leaning, or the gap is larger than one inch of shim plus two inches of plate can honestly fill. The stack comes apart. The footing is re-cut and, where the soil calls for it, enlarged. New blocks go up with cells vertical and courses crossed, a new solid cap goes on, and the pier is shimmed to the beam at the correct height. On a doublewide the marriage-line piers get the same treatment, because that row is what holds the seam closed.

The count is the whole price. A singlewide has 16 to 24 piers; a doublewide adds the center row. A home leveled every four years usually needs two to five rebuilds at most. A home that has gone ten years on a wet lot might need half its piers rebuilt, and that is when the pier work costs more than the relevel. You see it on the quote, pier by pier.

Pads, and why bigger beats taller

Florida’s rule starts a footing at a 16 by 16 inch excavation and assumes 1,000-pound soil when nobody has measured it. On the loose sands and wet flats around Wildwood that conservative floor is often the honest number. The lesson we apply to rebuilds is the one the rule implies: on soft ground you spread the load, you do not stack it higher. A pier that sank on a 16-inch pad gets rebuilt on a bigger one. That is why a rebuild costs more than a reset, and why it stays put.

Pricing

Pier work is almost always done as part of a relevel, and the pricing page shows how the two combine. If a home only needs a couple of piers rebuilt and the rest is fine, the crew will say so. A soft spot in the floor over one area is usually one or two of these, not a whole-home job.

Licensed, because the county checks

Every one of those steps is installation work under section 320.8249 of the Florida Statutes, and Sumter County Building Services on Powell Road in Wildwood issues its mobile home permit only to a licensed installer, with the blocking diagram submitted up front. All pier work arranged through us is performed by licensed, insured local installers.

If a corner of the home has dropped, a door has gone from sticking to not closing, or you have looked under the skirting and seen a stack that leans, request the free level check. We work across Wildwood, Oxford, Coleman, Bushnell, Webster, Lady Lake, and Leesburg, and the pier-by-pier map comes with the price.
