Pool contractors build, remodel and service something people swim in, which brings a different kind of liability than most trades. Owners deal with excavation, concrete and plumbing on the build side, chemicals and equipment on the service side, and contracts and certificates on both.

This page explains the insurance issues that matter to pool construction and pool service business owners in North Central and Northeast Florida, as plain education.

What pool owners deal with day to day

  • Drowning and injury claims. Claims can come from a barrier, gate, drain or alarm issue tied to work you did.
  • Structural problems. Cracking, leaks and settlement can show up long after the pool is finished.
  • Excavation. Digging near utilities, foundations and septic systems.
  • Chemicals. Storing and transporting chlorine and acid can lead to burns, fumes or spills.
  • Electrical. Pumps, heaters, lights and bonding create shock risk.
  • Service routes. Technicians are in customers’ backyards every day, around children and pets.

Typical claims in pool work

Without quoting statistics, pool contractors see claims for leaks and structural problems after completion, damage to the customer’s property during construction, chemical incidents on service routes, and injuries to people using the pool. Workers’ comp claims tend to involve strains from lifting, cuts, chemical exposure and heat. Auto claims come from trucks pulling equipment and service vehicles on daily routes.

What your contracts ask for, in plain words

Most of the insurance questions pool contractors face start in a contract, not a policy. Before you sign, read the insurance section and the indemnity section together, because one tells you what you promised to pay for and the other tells you what insurance has to back it up. These are the terms you’ll see most:

  • Minimum limits. The contract lists dollar amounts for general liability, auto, workers’ comp employer’s liability and often an umbrella. Your limits have to meet or beat those numbers on the day you start work.
  • Additional insured. The general contractor or owner wants to be covered under your policy for claims that come out of your work. Many contracts ask for this both while you’re working (ongoing operations) and after the job is done (completed operations), and the endorsement on your policy has to match what the contract says.
  • Waiver of subrogation. After your insurance company pays a claim, it normally has the right to go after whoever caused the loss. A waiver gives up that right against the party named in the contract. It usually takes an endorsement, sometimes on several policies including workers’ comp.
  • Primary and noncontributory. If the contract asks for it and your policy has an endorsement that provides it, your policy pays first for the other party’s covered claim and doesn’t ask their own insurance to share the loss. It isn’t automatic; it takes endorsement wording.
  • Per project aggregate. Some contracts want your general liability aggregate limit to apply separately to each job, so a large claim on one project doesn’t use up the limit for the others.
  • Homeowner and builder contracts. When you build for a homebuilder, their contract usually controls the insurance terms. When you build for a homeowner, your own contract does, so make sure it’s clear about warranty, completion and who handles barriers and alarms.

If a contract asks for something your policy can’t do, the time to find out is before you sign. Send us the insurance pages of the contract and we’ll tell you how they line up with your policy and what may need an endorsement. For indemnity and other legal terms, talk with your attorney.

Certificates of insurance: what you’ll be asked for

A certificate of insurance is the one-page summary a GC, owner or property manager asks to see before your crew can start. A certificate is for information only. It doesn’t change or add coverage, which is why careful GCs also ask for copies of the endorsements behind it. Expect requests to show:

  • Policy numbers, dates and limits for general liability, auto, workers’ comp and umbrella
  • The certificate holder’s exact legal name and address
  • Additional insured, waiver of subrogation and primary and noncontributory wording, with the endorsement forms attached when the contract calls for them
  • Workers’ comp coverage, or a copy of the exemption certificate for a qualifying corporate officer or LLC member

Keep one person in your office in charge of certificates, and keep a list of which jobs need updated ones at renewal. You can send requests through our certificate request form.

Workers’ comp for your crew and your subs

Florida treats pool construction, installation and repair as construction for workers’ comp. That changes the rules in three ways owners feel directly.

  • One employee is enough. In construction, a business with even one employee has to carry workers’ comp, and an owner who is a corporate officer or LLC member counts unless they’ve filed an exemption. Most non-construction businesses don’t have to until they have four or more employees, full- or part-time.
  • Officer exemptions are narrower. Up to three corporate officers or LLC members who each own at least 10% of the business (three total across affiliated companies) can apply for an exemption through the Division of Workers’ Compensation. It costs $50, lasts two years and is renewed online. An exempt officer or member isn’t covered for their own injuries, so think about health and disability coverage too.
  • You’re responsible for uninsured subs. Under Florida law, if a sub doesn’t have coverage, the contractor above them is treated as the employer of that sub’s workers for comp purposes. That’s why you have to collect each sub’s certificate or exemption before they start, and why it has to stay current for the whole job.

Why audits bring surprise charges

Comp premium starts as an estimate based on the payroll you expect. After the policy ends, the insurance company audits the real numbers. Florida’s audit rules tell auditors to review every source of payment to employees, subcontractors and independent contractors, and to look at the certificates your subs gave you. If a sub can’t show workers’ comp coverage or a valid exemption, Florida law counts the people you paid through that sub as your employees for comp purposes, so the auditor can add those payments to your payroll and charge premium on them. Construction employers large enough to have an experience mod must be audited at least once a year.

Being uninsured is expensive too. The state can issue a stop-work order, and the penalty is two times what the employer would have paid in premium over the prior 12 months, or $1,000, whichever is more.

Report every injury to us or your insurance company right away. Florida requires the employer to report an injury to its carrier within 7 days after learning of it. Read more on our workers’ compensation page.

Build crews versus service routes

Building, installing or repairing pools is construction for workers’ comp, so one employee is enough. A company that only cleans and services pools generally follows the four-employee rule, but if any of your work is pool repair or installation, the one-employee rule applies to the whole business. Many pool companies do both, which affects how payroll is split between class codes. Tell us how your people spend their time, because the right class codes matter at audit.

Your experience mod (EMR): what it is and why GCs ask

If your workers’ comp premium is large enough, your business gets an experience modification factor, often called the mod or EMR. It compares your company’s actual workers’ comp losses with what’s expected for a business of your size doing the same type of work. A mod of 1.00 is average. Below 1.00 is a credit, and above 1.00 is a debit that raises your premium. Small or new businesses that don’t meet the size threshold don’t have one.

Who calculates it in Florida

Florida uses the experience rating plan run by NCCI, the National Council on Compensation Insurance. NCCI calculates the mod, not your agent and not your insurance company. It normally uses three years of payroll and claims, and it leaves out the most recent year before the mod takes effect, because those claims are still too new to judge.

Why it matters when you bid

General contractors, owners and bid packages often ask for your mod, and some use it to prequalify pool builders before you’re allowed to bid. A mod above 1.00 can keep you off a bid list even when your price is right, because the GC reads it as a sign of how safely you work.

Why frequency usually moves it more than one big claim

The formula weighs the first part of every claim heavily and only part of the cost above that. So a string of small injuries usually raises a mod more than one large one. Under NCCI’s experience rating plan, a medical-only claim (one with no lost-time benefits) generally counts at only 30% of its cost in your mod where NCCI’s Experience Rating Adjustment applies. Report every injury, even small ones. Florida requires employers to report an injury to their insurance company within 7 days of learning of it, and paying a claim yourself instead of reporting it can put you out of compliance and leave the worker without benefits the law gives them. Where the ERA applies, medical-only claims already count at a reduced value in the mod, so there’s little reason to pay them yourself.

What you can do about your mod

  • Run a written safety program that fits your actual work, and hold short, regular crew talks, for example on lifting, chemical handling and heat
  • Report every injury the same day, so the claim is handled before costs grow
  • Offer light or modified duty so injured workers can come back sooner, since lost-time claims usually cost more than medical-only ones
  • Ask us for your mod worksheet each year and check it: wrong payroll, a claim that isn’t yours or a closed claim still showing reserves can all push the number up
  • Make sure each employee is in the right class code and your payroll is reported correctly, because the mod is built on those numbers

Trucks, tools and equipment

Service trucks carrying chemicals should be on a commercial auto policy, with drivers listed and their records checked. If employees drive their own vehicles for work, hired and non-owned auto coverage can respond, subject to the policy’s terms and limits, if your business is held responsible for an accident they cause. The employee’s own auto policy usually pays first, and this coverage doesn’t pay for damage to the employee’s car or protect the employee personally. See our post on employees driving personal vehicles.

Pumps, vacuums and testing equipment should be covered by inland marine. Keep chemicals secured and separated in vehicles and at your shop.

Florida licensing and pool safety rules

Florida licenses commercial pool/spa contractors, residential pool/spa contractors and swimming pool/spa servicing contractors through the Construction Industry Licensing Board. Cleaning and using equipment for water treatment doesn’t require a license unless the work involves building, modifying or replacing that equipment.

For new residential pools, Florida’s Residential Swimming Pool Safety Act requires at least one safety feature to pass final inspection: a barrier that meets the statute, an approved safety cover, exit alarms on doors and windows that open to the pool, self-closing and self-latching doors with the release at least 54 inches above the floor, or a swimming pool alarm that meets the referenced ASTM standard. The feature you choose and install should be documented in the job file.

See Florida contractor license insurance and bond rules for the minimum amounts, audits and bond rules.

Practical risk management steps

  • Document the safety feature on every new pool and get the owner’s signature
  • Photograph the site and neighboring property before excavation
  • Call Sunshine 811 before digging
  • Store and transport chemicals in approved containers, separated by type
  • Train service technicians on chemical handling and what to do with a spill
  • Check bonding and grounding on every equipment install
  • Keep gate latches and barrier checks on your service checklist and note problems for the owner in writing

Questions to ask before you renew

  • Are my build and service payrolls split into the right class codes?
  • Does my general liability have any exclusion for pools, diving boards or slides?
  • Is completed operations included, and for how long?
  • Do I need pollution coverage for chemicals?
  • Are my trucks and drivers listed correctly?
  • What will my experience mod be, and is the worksheet correct?

Frequently asked questions

Do pool service companies need workers’ comp with one employee?

A company that only cleans and services pools generally follows Florida’s four-employee rule. If any of your work is building, installing or repairing pools, Florida treats the whole business as construction, and one employee is enough.

What safety features does a new residential pool need in Florida?

At least one of the features listed in the Residential Swimming Pool Safety Act, such as a compliant barrier, an approved safety cover, exit alarms, self-closing and self-latching doors, or a compliant pool alarm.

Does general liability cover a leak after the pool is finished?

Usually that’s a completed operations claim. Check your policy for exclusions on faulty workmanship, which usually isn’t covered by itself. See how the “your work” exclusion works.

Do I need a license to clean pools?

Cleaning without building, modifying or replacing equipment doesn’t require a state license. Repair and equipment replacement do.

Are chemical spills covered?

Many general liability policies exclude pollution. Contractor’s pollution liability can cover chemical releases, depending on the policy.

What is an experience mod?

It’s a number NCCI calculates from about three years of your workers’ comp payroll and claims, leaving out the most recent year. 1.00 is average.
