How much does a seawall cost in Boca Raton?
Most residential seawall replacements in Boca Raton run between $900 and $1,800 per linear foot installed, depending on wall height, pile depth, cap design, water depth, access, and whether tiebacks are required. A typical 100-foot residential composite (vinyl + concrete-filled) seawall runs $90K–$140K; traditional concrete generally costs more on install and substantially more over the life of the wall. Cap-only repairs and tieback installations are significantly less. See the pricing table above for current ranges. We provide a free written quote after an on-site evaluation — no estimates over the phone, because every wall is different.
Why do you recommend composite over concrete?
Because of how traditional concrete seawalls fail in saltwater. The rebar inside a concrete wall sits in a chloride-rich environment for decades. Eventually it corrodes, expands, and cracks the concrete from the inside out — what's called spalling. That's why nearly every concrete seawall in South Florida starts showing structural distress between year 25 and year 40.
A composite wall — vinyl exterior over a concrete-filled core (Truline and similar systems) — solves the failure mode. The vinyl shell is the saltwater barrier. The concrete sits inside, never exposed to chloride, never corroded. Independent testing supports 75+ year service life with effectively zero maintenance cost. Traditional concrete still wins on commercial loads, certain deep-water installations, and HOA-specified aesthetics — and we install it when the application calls for it.
How long does a seawall last?
Properly engineered and installed: composite (vinyl + concrete-filled core) is rated for 75+ years; traditional concrete typically delivers 30 to 40 years in South Florida saltwater before structural restoration is needed. Both fail earlier when they're under-engineered, when soil behind the wall washes out for years before anyone notices, or when nobody installs jet filters or weep holes to relieve hydrostatic pressure. The single biggest predictor of seawall life isn't material — it's how well the install handled the things behind and below the wall.
Do I need to comply with the new NAVD88 cap height rules?
Yes, and the deadlines matter. Broward County requires minimum seawall cap elevations of 4.0 ft NAVD88 by 2035 and 5.0 ft NAVD88 by 2050. Fort Lauderdale has already moved to 5.0 ft. Boca Raton and Palm Beach jurisdictions are tracking similar regulatory direction. If your wall doesn't meet the current code at replacement, you'll be required to bring it up — which means either a taller cap or a fully new wall. We measure your existing elevation against current and future code on the first site visit, and design accordingly.
What does a composite seawall cost to maintain?
Effectively zero structural maintenance cost over its service life. The vinyl shell is UV-stable and won't fade, won't corrode, and won't spall. There's no painting, no sealing, no rebar replacement, no cap rebuild. Periodic visual inspection — same as any wall — and that's the whole list. Compare that to a concrete wall, which typically needs cap repair somewhere between year 15 and year 25, full restoration around year 30, and replacement in the 30–40 year range.
Do I need a permit for seawall work in Boca Raton?
Yes — always. City of Boca Raton requires a marine construction permit for new seawalls, cap replacements, and most repair work. Depending on your shoreline, you may also need Palm Beach County, FDEP (Florida Department of Environmental Protection), and Army Corps of Engineers review — especially if you're oceanfront, on the Intracoastal, or in an environmentally sensitive area. HOA architectural approval is separate and often parallel. We handle the full permitting process in-house and strive to deliver every standard project from signed contract through final inspection within 180 days. Permitting alone runs 4 to 12 weeks depending on jurisdiction and engineering review.
Can you repair my existing seawall instead of replacing it?
Often, yes — and we'll tell you honestly which is the better call. If your wall has cap cracking, voids behind it from soil washout, or is leaning slightly outward from missing tiebacks, repair work usually solves it: cap restoration, polyurethane void filling, deadman or helical tiebacks, and jet filter installation. If the wall is structurally compromised — major spalling, exposed rebar, panels failing, or significant outward rotation — replacement is the answer. The site visit tells us which.
How long does the actual install take?
For a typical 100-foot residential seawall replacement, expect 2 to 4 weeks of active install once permits are issued and materials are on site. Full project timeline from first site visit to completed install runs 8 to 16 weeks, driven primarily by permit processing. Cap-only work and tieback installs are faster — often 1 to 2 weeks of field work.
What's the warranty?
Composite systems carry manufacturer warranties on the sheet pile — typically 30 to 50 years depending on product, with documented service life beyond 75 years. Traditional concrete carries no factory warranty by nature of the material. Across both, we warrant our installation workmanship for 8 years — substantially longer than most contractors in this market. As the installing contractor we handle any warranty claim directly; you don't chase a manufacturer.
What about the dock, lift, or pool deck attached to the seawall?
Most seawall work touches the dock, the lift, or the pool deck behind it. Because we hold marine, general, electrical, and plumbing licenses in-house, dock removal and reinstallation, lift demobilization, pool deck cuts, and electrical isolation all go into the same contract from the same company — not three separate trades coordinating across three schedules. That's where projects usually fall apart, and where we save the most time.
How do payments work? Do you require a large deposit?
No. Projects are billed in stages tied to verifiable progress — typically a deposit at contract signing, draws at permit issuance, material delivery, installation milestones, and final inspection. You never pay for work that hasn't been completed. Large up-front deposits are a red flag in marine construction; we don't ask for them and you shouldn't pay them to anyone who does. Total project amounts are agreed in writing before we mobilize.
How can I verify your licenses and insurance?
Florida contractor licenses are public record. Search the Florida Department of Business and Professional Regulation (DBPR) license lookup at myfloridalicense.com using our business name. We carry general liability, Florida workers' compensation, and marine operations coverage. We provide certificates of insurance naming you (or your HOA, GC, or lender) as additional insured before mobilization — no exceptions. Ask for it before any contractor starts work, with us or anyone else.
Do you handle HOA approvals?
Yes. Most Boca communities — Royal Palm Yacht Club, Boca Raton Bridges, Hillsboro Mile estates, and others — require HOA architectural approval in addition to City permits. We prepare drawings to HOA spec, attend committee meetings where required, and coordinate the parallel approval process so your timeline doesn't stretch.
What if my seawall fails during a storm — can you respond?
Yes. Storm damage, partial wall failure, and active soil loss get prioritized over standard scheduling. If you call after a storm and the wall is failing, we move you to the front of the response queue. For documented emergencies we can usually have an owner on site within 24 to 48 hours for assessment and an emergency tarp or shoring plan if needed — followed by the proper engineered repair on a permit-ready timeline.
Do you take on smaller jobs, or only full seawall replacements?
Both. Cap restorations, tieback installations, void filling, and jet filter retrofits all run in the $8K–$60K range and are how a lot of clients first work with us. We don't have a minimum project size — we have a minimum standard of engineering. If repair is the right answer for your wall, we'll quote the repair. If replacement is the right answer, we'll quote that.
