Florida Water Intrusion Attorney

If your building leaks and no one has found the source, the cause is usually a construction defect in the building envelope, and Florida law lets you hold the builder, contractor, or developer responsible for finding it and paying to fix it correctly. Cory Cannon represents homeowners, condominium and homeowners associations, and commercial property owners across Tampa Bay in water intrusion claims against builders, general contractors, subcontractors, developers, and design professionals. Our job has three parts: find the failure, prove who is responsible for it, and recover the cost of fixing it correctly. We offer a free consultation, and the deadlines discussed below are a good reason not to wait on it.

You know the pattern. Water appears after some storms and not others; a contractor caulked something last spring, the stain came back in the fall, and now there is a musty smell in a room that has no plumbing. This page is for the property owner whose building leaks from a source no one has found, or from more places than anyone has been willing to admit.

One distinction before anything else. If a storm suddenly put water in your building and your fight is with your insurance company over what the policy should pay, that is an insurance dispute, not a construction defect dispute. Start with our property insurance claims practice or, for that specific problem, the water damage insurance claim page. This page is about water that gets in because something was built wrong.

What Water Intrusion Means in a Construction Defect Case

Water intrusion is water entering a building through its envelope. The building envelope is everything that separates inside from outside: the roof assembly, the exterior walls and their cladding, the windows and doors, the waterproofing layers behind the finishes, the flashings that bridge the joints between components, and the foundation. A building does not keep water out with any single barrier. It uses a system of overlapping components, each one designed to catch water and hand it off to the next until the water drains away from the structure.

When that system is designed wrong, installed wrong, or assembled in the wrong sequence, the building leaks. Sometimes it leaks immediately. More often it leaks gradually: a concealed defect can wet the structure a little with every driving rain for years before anything visible appears inside. Florida law calls that a latent defect: a defect that is hidden and would not be discovered through ordinary observation. Most serious water intrusion cases involve latent defects, and that classification drives the legal deadlines covered later on this page.

Rain is not a defect. Every structure in Tampa Bay takes wind-driven rain, and a building assembled correctly sheds it. A building that leaks under conditions the building code and the construction contract required it to withstand has a construction problem, and construction problems have legally responsible parties.

Signs the Problem Is the Construction, Not the Weather

A single leak after an extreme storm tells you very little. A pattern tells you a great deal. The indicators below, especially in combination and especially in a building less than ten years old, point toward a defect in the envelope rather than bad luck:

• Leaks recur in the same areas after rain, particularly rain driven from one direction.
• Stains return after repainting or patching.
• A musty odor or visible mold appears in rooms with no plumbing.
• Baseboards swell, flooring cups or buckles, or fasteners and corner beads show rust shadows through the finish.
• White mineral deposits appear on masonry or concrete. That residue is called efflorescence, and it is left behind when water migrates through the material and evaporates.
• Indoor humidity stays high even when the air conditioning runs normally.
• The building is relatively new, or the problems began after a remodel or addition.
• The builder or a repair contractor has already “fixed” it, more than once, and it held only until the next hard rain.

None of these proves a defect on its own. Together they justify a forensic investigation, because if a defect exists, the legal clock may already be running whether or not anyone has found the source.

Why No One Can Find the Source: How We Approach It

Water almost never appears where it enters. It follows gravity and the path of least resistance: down a stud cavity, along the top of a beam, across the back of a housewrap, under a floor to the first opening it finds. The stain on your ceiling can sit twenty feet from the breach that caused it. That is why three contractors can inspect the same damage in good faith and give you three different answers: each of them is looking at the exit point, and the dispute is about the entry point.

Intermittency makes it harder. Many envelope failures leak only under specific conditions: rain at a certain angle, wind pressure from a certain direction, a gutter overwhelmed past a certain volume. A defect that produces water twice a year is still a defect, and it is still wetting concealed framing on the days you never notice.

Finding the entry point is an engineering exercise, and we treat it as one. We retain independent licensed engineers and building-envelope consultants to run the investigation in a defined order:

• Moisture mapping. Meter readings and scans across walls, ceilings, and floors establish where the assembly is wet, how wet, and in what pattern, before anyone forms a theory.
• Infrared thermography. A thermal camera reads surface temperature differences that wet materials create, tracing moisture paths behind finishes without opening anything.
• Controlled water testing. Spraying targeted areas of the exterior in a set sequence, while observers watch the interior, recreates the leak under documented conditions instead of waiting for the right storm.
• Targeted destructive testing. Opening finishes or cladding at selected locations exposes the concealed layers so the actual construction can be compared against the plans and the code. Destructive testing means exactly what it sounds like, which is why it is done sparingly, photographed thoroughly, and, in the pre-suit process described below, often coordinated with the builder’s side.
• Document review. Plans, permits, shop drawings, inspection records, and change orders show what was supposed to be built. The testing shows what was actually built. The gap between the two is the case.

I am a Florida attorney with a family history in construction for generations. That matters here in a specific way: when the engineers report how an assembly was supposed to shed water and where the installation departed from it, I read those findings in the language they were written in, and I can question the other side’s consultants in it too.

The end product is a defect report that ties each entry point to a responsible party, which is what a claim needs, and what a tube of caulk can never give you.

If You Already Know Where the Water Gets In

This page exists for the whole-building problem: the leak with no confirmed source, or the building failing in several places at once. If an investigation has already isolated the failure to a specific component, the detailed discussion of that component lives on its own page:

• Water entering through the roof system: roofing defect claims.
• Water entering at windows, sliding glass doors, or entry doors: window and door defect claims.
• A building product that failed on its own terms: defective building materials claims.
• A building that was built as drawn, but drawn wrong: design defect claims.
• Condominium or HOA buildings, where the association owns the claim: association defect claims.
• A recently completed home still inside the builder’s warranty window: new construction defect claims.

For the practice as a whole, start at our construction defects overview. And note that these categories are not exclusive: buildings that leak often leak at more than one component, and a single claim can, and usually should, cover all of them.

Who Is Legally Responsible for Water Intrusion

Responsibility follows the work. Depending on where the water enters and why, the responsible parties may include:

• The general contractor or builder, who is responsible for the overall assembly, including the coordination and sequencing between trades, which is where many envelope failures are born.
• Subcontractors who installed the specific failed component.
• The developer, particularly in new communities and condominium projects, who sold the finished product.
• Design professionals (architects and engineers), where the drawings or details themselves were deficient.
• Manufacturers and suppliers, where a product failed even though it was installed as directed.

Florida law gives owners several routes to hold those parties accountable, and most water intrusion cases plead more than one:

• Breach of contract, where the work departed from the plans, specifications, or contract terms.
• Breach of implied warranty. Florida courts recognize implied warranties of fitness and merchantability on the sale of a new home by a builder or developer: unwritten promises, imposed by law, that the home was built in a workmanlike manner and is fit to live in.
• Negligence, where the work fell below the standard of care.
• Violation of the Florida Building Code. Section 553.84, Florida Statutes creates a civil cause of action for damage caused by code violations. It carries an important limitation: where the work was permitted, the plans were approved, and the project passed inspections, the owner generally must show the violator knew or should have known the violation existed. Concealed envelope work, the layers an inspector never sees, is where that showing is often made.

Which theories fit, and against whom, depends on your contract, the age of the building, and what the investigation finds. For a broader walkthrough of claims against builders and contractors, see our guide on suing a contractor in Florida.

Mold From a Construction Defect

Sustained moisture inside a wall or ceiling grows mold. It does not need a flood; it needs a food source and time, and a slow envelope leak supplies both. Mold discovered in a room with no plumbing is one of the most common ways owners first learn they have a water intrusion problem at all.

Two points matter legally. First, remediation without repair is temporary. A remediation company can remove the mold, but if the entry point still exists, the moisture returns and so does the growth. Both costs, remediating the mold and repairing the defect that caused it, belong in the claim against the responsible parties. Second, document before you remediate. Photographs, moisture readings, any sampling reports, and the remediation invoices are evidence; once the material is gone, they are the only evidence. If occupants are experiencing symptoms, have the indoor air quality evaluated by qualified professionals: sensitivity to mold varies from person to person, and that is a question for them, not for us.

The Chapter 558 Notice Process

Florida does not let an owner walk a construction defect claim straight into court. Chapter 558, Florida Statutes requires a pre-suit exchange first:

• The owner serves a written notice of claim describing each alleged defect in reasonable detail, at least 60 days before filing suit, or at least 120 days for an association representing more than 20 parcels.
• The builder or contractor may inspect the property within 30 days of the notice, or 50 days in the larger association cases. A request for destructive testing must follow section 558.004(2).
• Within 45 days (75 for the larger association cases), the recipient must respond: an offer to repair, an offer to pay, a combination, or a statement disputing the claim.

The process is intended to resolve defects without litigation, and sometimes it does. But the notice is also the first formal document in the dispute, and its quality matters: a notice that describes the symptoms without identifying the failures invites a cosmetic repair offer that resolves nothing. This is why the forensic investigation comes before the notice, not after. We cover the process in detail, from both the owner’s side and the recipient’s side, in our chapter 558 notice guide.

Deadlines: Four Years, the Discovery Rule, and the Seven-Year Cliff

Two different clocks run on every Florida construction defect claim, and they work differently. A statute of limitations sets how long you have to sue once a claim accrues, and it can be moved by when the defect was discovered. A statute of repose sets an absolute outer limit measured from the construction itself, and nothing moves it, not even a defect nobody could have found. Both live in section 95.11(3)(b), Florida Statutes.

The 7-year repose period is recent. Before the 2023 legislation known as SB 360, the period was 10 years and ran from a later set of trigger dates. The change eliminated claims on many older buildings and shortened the runway on everything else, and it included transition rules for buildings completed before the amendment. Where a completion date sits near the changeover, have counsel confirm which version applies to your building. Two more features of the statute deserve attention: repairs to completed work, warranty or otherwise, do not extend the deadlines; and where a project consists of multiple buildings, each building is treated as its own improvement with its own clocks.

The practical rule is simple. If your building is roughly five to seven years past its certificate of occupancy and it leaks, the investigation is urgent: not because the damage will get dramatically worse this year, but because the right to recover for it may expire. These deadlines have exceptions and edge cases, and nothing here substitutes for having counsel run the dates on your specific facts.

What a Water Intrusion Claim Can Recover

The measure of damages depends on your contract and the facts, but a properly built claim typically pursues:

• The cost to repair the defective work correctly: the actual fix, not the patch that failed twice already.
• Resulting damage to the structure and interior: rotted framing and sheathing, ruined drywall, flooring, and cabinetry.
• Mold remediation and post-remediation verification.
• Investigation costs, where recoverable, for the engineering work that found the problem.
• Loss of use or relocation costs where the facts support them, and in some cases the reduction in the property’s value.

Numbers get contested in these cases the same way they do everywhere else in construction: with competing estimates. When the other side prices the repair, we check their figures line by line against real bids from licensed local contractors: a scope that repairs the exit point but leaves the entry point is not a repair, and it is priced like one.

How We Work and What It Costs

We litigate these cases the way they get investigated: document-first. Plans, permits, inspection records, warranty correspondence, repair invoices, and the engineers’ findings are assembled before positions get taken. I grew up around construction, and my approach reflects it: we expect to prove what was built, not to characterize it.

Owner-side defect claims may use contingency, hybrid, or hourly arrangements, depending on the claim, the responsible parties, and the construction contract. Many construction contracts contain prevailing-party attorney’s fee provisions, which can create fee exposure for either side. We explain the proposed fee structure, cost responsibilities, and any fee-shifting provision in writing before representation begins. The initial consultation is free.

What to Do Now

1. Document every event. Date, time, weather conditions, photographs, and video: each occurrence, every time. Intermittent leaks are proven with records, not recollections.
2. Keep the paper. Every repair invoice, every text and email with the builder, every warranty claim. Prior failed repairs are evidence of the defect and of what the builder knew.
3. Dry it out, but preserve the evidence. You have a duty to mitigate: a legal obligation to take reasonable steps to prevent the damage from growing. Dry the space and stop what you can stop, but photograph before you patch, and do not tear out and discard materials before they are documented.
4. Do not accept another cosmetic fix as the answer. Let the builder repair (chapter 558 is built around that opportunity), but on the record, in writing, against an identified defect.
5. Get the dates checked. Bring us the certificate of occupancy date and the history, and we will tell you where the clocks stand.
