Foundation Masters, LLC is the trusted house leveling specialist on Siesta Key. Our Florida licensed engineering team brings decades of structural and geotechnical experience to lift, level and stabilize homes across Siesta Key and Sarasota County.
We correct uneven floors, foundation settlement, crawl space deterioration and structural movement using engineered methods designed for barrier island conditions, coastal storms, high groundwater and sandy or limestone soils. From a simple floor lift to deep underpinning or a complete house relocation, we design a code compliant plan and handle the local permitting.
The thing that makes Siesta different from the mainland is the sand itself. The island is built of extremely clean, fine, uniform quartz sand. It is why the beach is famous, and it is also why foundation work here has to be designed rather than guessed at.

What Siesta Key Sand Does to a Foundation
Siesta Key is made of unusually clean quartz sand, fine and remarkably uniform in grain size. That is a pleasant thing to walk on and a demanding thing to build on. Clean uniform sand has almost no cohesion, so it holds nothing together on its own. It relies entirely on grain to grain contact and confinement, which means two conditions decide whether it carries your house: how dense it is, and whether water is moving through it.
That single property explains most of what we see on this island. Loose sand densifies under a footing and the footing goes down with it. Flowing water carries sand away and leaves a void that nothing warned you about. Neither failure announces itself from the surface, which is why elevation readings and borings matter more here than a visual walk around.
Densification Under Load
Uniform sand placed loose will tighten up when a house sits on it. The movement is slow, uneven across a slab, and continues until the sand reaches its denser state.
Sand Carried Away by Water
With no fines to bind it, island sand travels easily with flow. A leaking service line or concentrated runoff can empty the ground under a footing edge.
Tidal Groundwater
The water table sits high and rises and falls with the tide. Saturated sand carries less, and the cycling keeps fines on the move season after season.
Storm Surge Scour
Surge runs under and around a structure and takes sand with it on the way back out. The structural damage shows up well after the water is gone.
Canal and Seawall Lots
In Siesta Isles and the other canal neighborhoods the fill sits behind a wall. A tired seawall lets that sand leave, and the deck tells you before the house does.
Changed Sand Transport
The pass at the south end of the island was closed decades ago, and the way sand moves along this shoreline changed with it. Shoreline change is a condition to measure on a lot, not a headline to ignore.
Limestone at Depth
Where rock sits below the sand, the depth to it swings over short distances. Two neighboring lots can need two different pier depths, which is why we take data rather than reuse a number.
Older Block Cottages
A great deal of the island housing stock dates from the middle of the last century, built on shallow footings with light reinforcement. Those homes move early, and they also lift well when the design respects them.
Additions and Lanais
An addition or screen room poured later rarely sits on the same bearing as the original house. The separation crack at that joint is one of the most common calls we take from Siesta.
Older wood framed island houses on pier and beam foundations behave differently again. Those usually settle through the floor system rather than the perimeter, and they are smart jack jobs rather than pier jobs.
When a Siesta Key Home Needs Leveling
Owners usually call us about one crack. What we are actually looking for is a pattern, because a pattern has a direction and a direction points at a cause. Book an engineering inspection before you pay anyone to patch anything, since cosmetic work on a structure that is still moving is money spent twice.
What You See Indoors
- A floor that falls away toward one wall, or a spot that flexes underfoot
- Cracks leaving the top corners of doorways and window openings on an angle
- Interior doors catching at the head or the latch side
- A line opening between the baseboard and the floor, or at the ceiling
- Tile grout failing along one continuous line rather than randomly
What You See Outdoors
- Mortar joints in block cracking in a stair step up a wall
- A slab edge sitting low, or soil pulled down away from the foundation
- A lanai, screen room or carport separating at the joint with the house
- Sand moving at the foundation line after rain, or a hollow under the slab edge
- Girders, shims or piers in a crawl space that have gone soft or crushed
- Concrete breaking away with rust showing at a beam, column or tie beam
Choosing the Right Method on a Barrier Island
There is no best system in the abstract. There is a correct system for your soil, your structure, your load and your access, and on Siesta Key access is a design input rather than an afterthought. The island is reached by two bridges, the lots are narrow, and pool decks, seawalls and mature landscaping leave very little room for equipment.
Helical Piers
Turned to depth with the installing torque confirming capacity. No reaction weight is needed and the machine is small, which is why they solve most tight island lots.
Push Piers
Driven below the footing using the building weight as the reaction. The right answer on a heavier block structure with competent material at a reachable depth.
Smart Jacks
Adjustable steel supports on new engineered footings, placed under the girders so a settled floor comes back without disturbing the perimeter walls.
FM PP25 Push Pier
Our own push pier, engineered and specified in house so the bracket, the pipe and the connection to your footing are designed as a single assembly.
FM PP30 Pipe Pile
Heavier pipe for larger loads and deeper bearing. This is the system for the big Gulf front rebuilds and for additions that outgrew a residential pier.
Pressure Grouting
Where the problem is a void or loose sand rather than the depth of bearing, grout fills and densifies the zone instead of carrying the load somewhere else.
Temporary Shoring
Shoring makes the structure safe while the permanent repair is designed, permitted and built. On anything unsafe it is the first thing we do, not the last.
Concrete and Masonry Restoration
Spalled concrete cut back to sound material, reinforcement treated, section rebuilt. Salt air makes this part of most structural scopes out here.
Building Elevation
Raising a structure above the flood elevation is its own engineered project with its own permitting path, and it is a regular request on this island.
If a company names your method before anyone has looked at your soil, they are selling a product rather than solving your problem.
How a Siesta Key House Leveling Project Runs
1. Measured Inspection
We read the cracking and the drainage, then shoot floor elevations across the structure so you own a record of the movement in numbers rather than opinions.
2. Subsurface Data
In uniform sand the surface tells you very little, so where the design depends on depth to bearing we take soil borings and compute the footing loads.
3. Access and Logistics
Two bridges, narrow streets and seasonal traffic make staging a real part of the plan. Equipment, protection and delivery get settled before mobilization.
4. Sealed Design
Our licensed engineers choose the system, fix the pier or jack locations and depths, and issue signed and sealed drawings with the supporting calculations.
5. Sarasota County Permitting
Siesta Key is unincorporated, so permits go through Sarasota County rather than a city. We submit, answer plan review and carry the inspections.
6. Lift, Verify and Close Out
Installation, then a lift in controlled increments with elevations watched across the whole structure. You keep the sealed plans, the install record, closing readings and written warranty coverage.
Water control is part of the engineering, not a line item added at the end. Taking the load down to competent sand repairs the structure. Getting water away from the foundation is what stops the same failure reappearing twenty feet down the wall.

Why Choose Foundation Masters in Siesta Key
Licensed Florida engineering firm, CA# 30969, with decades of combined experience
Owner operated by Jeff Earl with Ken Sands, P.E. as Chief Engineer
Free on site inspections and preliminary engineering drawings
Fast permitting and code compliant documentation
Trusted by homeowners, builders and real estate professionals across Sarasota County
We design the repair, seal the plans, pull the permit and do the work, all from one office
An island job can change on you. A boring comes back different from the one next door, or the lift reveals framing nobody could see. A crew can only install what was sold. An engineering firm can stop, re measure, revise the design and push the revision through plan review without handing you the problem.
We are also willing to tell you to do nothing. If the elevations say your floor is inside tolerance and the cracking is cosmetic, that is what the report will say, along with what to keep an eye on. An honest no is worth as much as a yes.

House Leveling Siesta Key FAQs
These come up on nearly every first call from a Siesta Key owner. If yours is not here, call the office and ask it directly.
What causes a house to need leveling in Siesta Key?
High groundwater, coastal storms, sandy soils, plumbing leaks, and crawl space wood deterioration can lead to settlement and uneven floors on barrier islands.
How do you level a house in Siesta Key?
Depending on loads and soils, we use helical or push piers, pressure grouting, and structural shoring to lift and stabilize the structure, engineered to meet Florida Building Code and local permitting requirements.
Can you level and also move my house?
Yes. Foundation Masters is one of the leading house and building movers in Florida, providing engineering plans, permitting, and safe relocation.
How much does house leveling cost in Siesta Key?
Costs vary by home size, access, and settlement severity. Simple floor lifts may be a few thousand dollars, while deep underpinning or relocation is higher. We provide free inspections and detailed proposals.
Will I need to leave my home during leveling?
Many projects allow you to remain in place, while major lifts or structural replacement may require temporary relocation. We will advise before work begins.
Do you handle permitting and code compliance?
Yes. As a licensed engineering firm, we prepare plans, manage permitting, and coordinate with Sarasota County and local building departments to ensure compliance.
Why does the sand on Siesta Key matter to my foundation?
Because it is unusually clean and uniform, which means it has almost no cohesion. Sand like that carries a house well when it is dense and poorly when it is loose, and it moves easily with flowing water. Those two behaviors are behind most of the settlement we find on the island.
Do I need soil borings for a Siesta Key house leveling job?
Often, yes. Uniform sand gives very little away at the surface and the depth to competent material or to rock can change sharply between neighboring lots. Where the design turns on that depth, borings are the only way to work from measurement rather than assumption.
Can you even get equipment onto a narrow Siesta lot?
Usually, and that question is part of the design rather than an obstacle to it. Two bridges, narrow streets, pool decks and seawalls all limit what can reach the work, which is why helical piers come up so often here. We settle access and staging at the inspection, before anything is scheduled.
My addition is pulling away from the main house. Is that a foundation problem?
It usually is. An addition or screen room poured later rarely bears the same way as the original structure, so the two move independently and the joint opens. The repair starts by measuring both sides so the design addresses the part that is actually moving.
