Suspected Sinkhole Activity
Cracking, floor movement, or sticking doors have you worried about subsidence, and you need to know whether it is a sinkhole concern or ordinary settlement before you file or repair.

Years of Combined Structural & Forensic Experience
The "Century of Experience" Advantage
Independent Engineering: The evidence writes the report. We never perform the repairs we specify, so our conclusions have nothing to sell. On a suspected sinkhole claim, that independence matters enormously. Each assignment runs like a forensic case: conditions documented, movement analyzed, mechanisms identified, and the next step tied to evidence.
Why Structural Engineering in Lakeland Means Reading the Ground
The Forensic Truth
Polk County sits on karst geology: limestone bedrock that dissolves over time and leaves voids beneath the surface. That is what makes this sinkhole country.
A cracking wall in Lakeland raises a question a cracking wall in a non-karst region may not. Most alarming movement is ordinary settlement in sandy soil. Some of it is the early signature of subsidence over a developing void. Telling them apart is the entire job.
Our approach starts from failure investigation. We document crack patterns, floor elevations, door and window distortions, and other movement clues that distinguish sinkhole-related movement from normal settlement, expansive soils, or a drainage problem.
Where the evidence points toward subsidence, we coordinate with geotechnical testing rather than guessing. For Florida wind-load requirements, see the Florida Building Code.
Because we do not sell the repair, the report has no reason to reach for the more expensive conclusion. The finding answers to the evidence.

When Should You Call a Structural Engineer in Lakeland?
Four situations account for most calls, with additional support when a project or dispute needs confirmed structural findings.
Renovations & Additions
A wall is coming out or the footprint is growing, and the project needs sealed plans and calculations that clear City of Lakeland and Polk County review.
Disputes & Litigation
A defect, failure, or sinkhole claim is contested, and counsel needs cause-and-origin analysis and damage quantification that survive scrutiny.
Plan Review Comments
City of Lakeland or Polk County structural comments have stalled a project and need direct engineering responses from the professional sealing the work.
Foundation Settlement
The foundation appears to be moving, and you need to know whether the movement is active, historic, and what is actually driving it.
Forensic Damage
You need observed damage tied to evidence, movement patterns, and failure mechanisms so claims, repair scopes, and legal decisions rest on confirmed findings.
Load Evaluations
A planned use change, new load, or visible deflection requires a structural letter, load evaluation, or engineering opinion signed by a Florida professional engineer.
Drainage & Soil Movement
Poor drainage and soil moisture swings can mimic more serious movement. We separate a drainage-driven crack from a structural one so the fix targets the real cause.
What Our Lakeland Structural Engineering Includes
Sinkhole, Subsidence & Settlement Evaluations
We document the structural evidence that distinguishes sinkhole-related movement from ordinary settlement, coordinate with geotechnical testing where warranted, and report a defensible conclusion, whether that supports a claim or rules subsidence out.

Our Engineering Process
Three steps from first call to sealed deliverable.
Scope confirmed
Findings coordinated
Permit ready
Scope and Intake
Call Everest at (844) 322-2946 and describe the project or concern, whether that is cracking you fear is a sinkhole, foundation movement in a mid-century ranch, or an addition that needs sealed plans. We confirm jurisdiction and permit authority, then scope the work.
Scope confirmedInvestigate or Design
Assessments get on-site documentation: crack mapping, floor-elevation survey, door and window distortion, and analysis of the movement pattern. Where subsidence is a live question, we coordinate geotechnical testing. Design work gets full calculations and drawings.
Evidence tiedSealed Deliverables
You receive Florida PE-stamped documentation: a forensic report, a sinkhole or settlement determination, a litigation-ready analysis, or permit-ready plans, with plan-review responses handled directly where applicable.
Sealed deliveryThe Engineering Deliverable: Evidence-Based, Not Assumption-Based
A descriptive report records suspicion. Everest's prescriptive work records what is confirmed, why it happened, and what the structure requires.
Standard reports can stop at "possible sinkhole activity" with little movement analysis or evidentiary basis. That kind of conclusion falls apart in a claim or dispute.
Everest documents crack patterns, elevations, distortions, and geotechnical coordination where the evidence warrants it, then delivers a defensible conclusion from a firm that will not do the repair.
Structural Issues We See Across Polk County
These are the assignments that bring Lakeland owners, insurers, and attorneys to us most often.
Each scenario needs findings, plans, or documentation tied to evidence rather than assumption.
A homeowner sees cracking and fears the worst. We document the structural evidence, coordinate geotechnical testing where warranted, and report whether the pattern supports subsidence or points to ordinary settlement, either way with a defensible basis.
Central Florida's sandy soils settle, and most cracking traces to that rather than to a sinkhole. We determine whether movement is active or historic and what is actually driving it.
Sinkhole claims are among the most contested in Florida. Whether an owner needs support for a claim or an insurer needs an independent read, our forensic documentation gives the dispute an evidentiary footing.
Poor drainage and soil moisture swings cause movement that mimics more serious problems. We separate a drainage-driven crack from a structural one so the fix targets the real cause.
Opening a floor plan or adding square footage reroutes loads through the building. We design the beams, connections, and supports and deliver plans that pass Polk County review.
When a failure becomes a legal matter, the analysis has to survive an opposing expert. We provide cause-and-origin investigation, quantified damages, and testimony as matters proceed.
City of Lakeland and Polk County plan review comments can stall a project. We draft the responses ourselves, addressing the reviewer's technical points directly with the goal of resolving comments in one cycle.
Some projects need a targeted letter, load evaluation, or signed engineering opinion rather than a full plan set. Everest provides standalone deliverables for permits, insurance questions, transactions, claims, and disputes.
Frequently Asked Questions
It depends on the assignment. A focused settlement or sinkhole evaluation prices very differently from a full forensic damage assessment or a set of permit-ready plans. Describe the property and the concern, and we will quote the scope up front.
Usually not, but Polk County's karst geology is exactly why the question deserves a real answer. Most cracking traces to ordinary settlement in sandy soil. Some carries the signature of subsidence. We document the evidence that tells them apart rather than guessing in either direction.
Yes. We provide the structural evaluation that supports or challenges a sinkhole claim, coordinating with geotechnical testing where warranted. Because we do not sell the repair, our conclusion answers to the evidence rather than to an underpinning contract.
That is the core of the work. Crack patterns, floor elevations, and door and window distortions carry different signatures for subsidence versus ordinary settlement, drainage problems, or expansive soils. We document those signatures and report a defensible conclusion.
That is the goal of every set we seal. We confirm the permit authority before we start, produce full calculations with the drawings, and draft responses to plan-review comments ourselves so approvals do not stall on translation.
Yes. Our reports are built to withstand opposing scrutiny, and we support attorneys and claims professionals through mediation, arbitration, and trial, which matters given how often sinkhole claims are contested.
Yes. We work across Lakeland and Polk County, including the historic districts, the mid-century neighborhoods, and the newer master-planned areas, with statewide coverage beyond it.
No. We provide independent engineering only. We do not perform the repair or construction work we specify, which keeps our assessments neutral and our documentation defensible for owners, insurers, and counsel.
