In short
- A seawall warning signs calculator turns the failure signs from our guide into one next step: monitor, book an inspection, or get one soon.
- You tick seven signs as none, minor or growing. Each gets an urgency of Monitor, Moderate or High, taken from the ratings in our failure-signs guide.
- Example: thin cap cracks, a small stable sinkhole and a little rust are three signs and give Get an inspection soon. With only the first two, it gives Book an inspection.
- It is a visual triage only. We are a referral service, not an inspector.

This seawall warning signs calculator is for Cape Coral homeowners who spotted something odd on a canal seawall and want to know how urgent it is. You tick each of seven signs as none, minor or growing. The tool shows an urgency for each one and a single overall next step, using the ratings published in our guide to seawall failure signs. We are an independent referral service that connects visitors with independent local contractors, not a contractor or an inspector.

How the rating works
- Tick each sign.
Use the hint under each line. Choose None seen, Minor or Growing. If you cannot tell, pick Minor and look again at the next low tide.
- Each sign gets an urgency.
Every sign has a rating from our guide, such as High for a lean or failing tiebacks. A Growing choice moves most signs up to High. Table below.
- Add them up.
Any High, or three or more signs at once, gives Get an inspection soon. A Moderate or two signs gives Book an inspection. One low sign gives Monitor.
Table: urgency by sign and how it looks
Ratings come from the urgency column of our failure-signs guide. Where the guide says "moderate to high" we use Moderate for Minor and High for Growing. Combining several signs into one verdict is our planning assumption, not a standard.
| Sign | Minor | Growing |
|---|---|---|
| Cracks in the cap | Monitor | High |
| Gaps between panels | Moderate | High |
| Lean or rotation | High | High |
| Sinkholes behind the wall | Moderate | High |
| Soil washing out at low tide | Moderate | High |
| Rust, spalling, exposed steel | Monitor | High |
| Signs of failing tiebacks | High | High |
Example with three signs
A thin crack in the cap, a small stable dip behind the wall and a little rust in one spot. Nothing else seen. That is three signs, one of them Moderate.
| Sign | You ticked | Urgency |
|---|---|---|
| Cracks in the cap | Minor | Monitor |
| Gaps between panels | None seen | None |
| Lean or rotation | None seen | None |
| Sinkholes behind the wall | Minor | Moderate |
| Soil washing out at low tide | None seen | None |
| Rust, spalling, exposed steel | Minor | Monitor |
| Signs of failing tiebacks | None seen | None |
Overall: get an inspection soon
What the result leaves out
- Anything you cannot see. Tiebacks, anchors and the base of the wall are hidden. Confirming them needs probing or excavation by a professional.
- Storm effects. After a hurricane or king tide, check again even if the result was low before.
- Fresh water or salt. Tidal canals and freshwater canals behave differently, so ask a local pro which you have.
- Safety. Never climb on the wall, go in the water or dig beside it to look closer.
Questions to ask when you call for an inspection
- What will you look at? Ask whether it covers the cap, joints, panels, tiebacks and the soil behind the wall.
- How will you check the tiebacks? Ask what probing or digging is needed and what it disturbs.
- What is in the written report? Ask for photos, measurements and a clear repair-or-replace opinion.
- Is a repair enough? Ask how a repair would stop the soil loss, not only fill the hole.
- Who pulls the permit? See the permit guide.

Next step: get an opinion
This result is a triage, not a diagnosis or a quote. Use the request form on this page to be connected with independent local marine contractors. We are a referral service, not a contractor, and we cannot vouch for any contractor, so verify licence and insurance yourself.

Frequently asked questions
How do I know if my seawall is failing?
Look for a cap that is no longer straight, gaps between panels, sinkholes behind the wall, soil washing out at low tide, rust or spalling, and cracks that are wide or growing. Our guide rates a lean and failing tiebacks as the most urgent. Only an in-person inspection can say whether the wall is failing.
Is a crack in my seawall cap serious?
Thin hairline cracks are common in concrete and are usually monitored: photograph and date them. Wide, full-width, growing or offset cracks suggest the wall below is moving and are worth an inspection.
Is this an inspection?
No. It only sorts what you can see from the yard into a next step. We are a referral service, not an inspector or engineer, and the combining rule is our own planning assumption.
What should I do after a storm?
Walk the wall once it is safe, photograph everything with a date, and look at the face again at the next low tide. Do this before any cleanup if you may file an insurance claim. Run the checker again with what you find.
Why does a lean always rate High?
Our guide treats a lean as a structural sign: it usually means failed tiebacks, a compromised base or soil pressure the wall cannot hold. It can slump further in a storm, so the guide says to call promptly.
