Pool Contractors

The federal law named for a child who drowned in a pool covers public pools and does not reach a single-family backyard. The barrier that does apply comes from a model code each state or city has to adopt, and it usually sits in the excluded column of the builder's quote while being a condition of the permit. An inground pool runs about $25,000 to $100,000, and which of the three shells you pick moves both that number and every year after it.

How do we know these prices?

Every figure above comes from a named source we can link to, with the date we last checked it. We publish ranges rather than single prices because a range is what a provider will actually give you: the same job moves with what is being worked on, the materials, how hard it is to get at and how busy the trade is locally. Treat these as the order of magnitude to expect before you call, not as a quote.

The figures here are national. Where a source publishes figures state by state, the state pages carry that local figure instead of this one. We do not scale a national number by a multiplier of our own invention.

Every range carries a review date. When that date passes the number comes down until it is rechecked, rather than sitting here undated.

  • HomeGuide inground pool cost guide checked September 2026Two guides disagree at the low end by about $20,000. HomeGuide, updated July 2025, gives $25,000 to $100,000 at $80 to $250 a square foot. Angi, updated August 2026, gives a typical range of $44,499 to $87,349 with a $65,909 average and a full span of about $14,000 to $135,000. HomeGuide's wider band is used here and Angi's is published alongside it.
  • HomeGuide gunite pool cost guide checked September 2026Angi, updated August 2026, gives $65,000 to $120,000 for concrete. Build time is six to eight weeks and the concrete needs 30 days or more to cure.
  • HomeGuide fiberglass pool cost guide checked September 2026Angi, updated August 2026, gives $55,000 to $100,000. The shell is quoted at 25 years or more and sets within a day or two of the excavation.
  • HomeGuide vinyl liner pool cost guide checked September 2026This is the widest proportional disagreement of the three types. Angi, updated August 2026, gives $40,000 to $75,000 where HomeGuide gives $25,000 to $65,000. HomeGuide also contradicts itself on liner life: its vinyl page says five to fifteen years at $2,000 to $7,500, its inground page says about every ten years at $3,000 to $7,500.
  • HomeGuide pool resurfacing cost guide checked September 2026HomeGuide and Angi agree exactly on the job-level range and average of about $11,000, then disagree per square foot in opposite directions on the two commonest finishes. HomeGuide, April 2025, gives plaster $6 to $8 and tile $8 to $30 or more. Angi, August 2026, gives plaster around $4 and tile $25 to $35. Standard plaster lasts seven to twelve years, quartz ten to fifteen.
  • HomeGuide pool leak detection cost guide checked September 2026Above-ground detection runs $100 to $500. These figures rest on a single publisher and carry no cross-check.

What the base quote leaves out

Three shells, three different decades

An inground pool is built one of three ways, and the choice decides more than the install price. A vinyl liner is the cheapest to put in and the only one with a wearing part, because the liner itself is replaced every five to fifteen years. Gunite, which is sprayed concrete, costs the most to build and needs resurfacing every seven to fifteen years. A fiberglass shell arrives in one piece, drops in within a day or two of the excavation, and is quoted at twenty-five years or more.

Running costs sort in the opposite direction to the sticker. Angi puts annual upkeep on a concrete pool at roughly twice a vinyl one and several times a fiberglass one, and HomeGuide notes concrete uses about three times the chemicals, because the surface is porous. A cheap shell with an expensive decade behind it is a real trade, and it is rarely presented as one.

The federal pool safety law does not reach a backyard

The Virginia Graeme Baker Pool and Spa Safety Act took effect on 19 December 2008 and is the one piece of federal law in this trade. It requires anti-entrapment drain covers meeting a referenced standard, and a second layer of protection on any pool with a single blockable main drain. It is named for a seven-year-old who drowned after being held under by suction.

It applies to public pools and spas: facilities open to the public, those open to members of an organization and their guests, pools serving multi-unit housing, and pools the federal government operates for service members and their families. A single-family residential pool sits outside it. The Consumer Product Safety Commission counts 357 child drownings a year on a 2020 to 2022 average, with 74 percent of reported deaths in residential settings and 53 percent of those with a known type in inground pools. The pools the federal law covers are not the pools where the deaths happen.

The fence is a permit condition, not a quote line

What governs a residential barrier is a model code, adopted or not by each state and city. Section 305 of the 2018 International Swimming Pool and Spa Code sets the barrier at not less than 48 inches above grade, measured on the side facing away from the pool. Ground clearance is capped at two inches over grass or gravel and four inches over a solid surface, and openings must not pass a four-inch sphere. Pedestrian gates open outward, self-close and self-latch. Where a wall of the house forms part of the barrier, operable doors and windows with low sills take an alarm listed to UL 2017.

The Consumer Product Safety Commission publishes its own barrier guidelines and says inside the document that they are not a CPSC standard and not mandatory requirements. So the 48 inches everyone quotes carries force only where a jurisdiction adopted a code that says it, which makes it a local question rather than a national one.

Meanwhile fencing sits in the excluded column of most builders quotes, alongside decking, landscaping, lighting and the heater. That gap is worth pricing before signing, because the barrier is generally a condition of the permit and generally not in the base number.

Some states name pools, and some license nothing

California issues a C-53 Swimming Pool Contractor classification through the Contractors State License Board, defined at 16 CCR 832.53 as constructing swimming pools, spas or hot tubs including solar heating equipment. Florida sets pool contracting in statute at section 489.105(3) in commercial, residential and servicing forms, and draws a distinction worth knowing: a certified contractor may work anywhere in the state, while a registered contractor has met one local jurisdiction's requirements and may work only there. Nevada's A-10 classification at NAC 624.150(10) covers commercial and residential pools and spas. Virginia carries a POL specialty for swimming pool construction, and Arizona keeps several pool classifications at its Registrar of Contractors.

Texas licenses no pool contractor and no general building contractor at state level. Its Department of Licensing and Regulation runs 41 programs and none of them is pool building, so the credential that exists there is municipal, alongside the separate state licenses for electrical and plumbing work. Electrical is its own question everywhere, because NEC article 680 requires equipotential bonding on permanently installed inground pools, tying shell steel, perimeter surfaces, metal components and underwater lighting together in copper. A California C-53 holder may do that work as incidental and supplemental to building the pool. In Texas the electrician holds a state license the pool builder does not.

Paying ahead of the work is this trade's structural risk

A pool takes eight to twelve weeks and is paid in stages, a structure that rewards a builder who collects faster than they build. Two states cap the opening payment. California limits a home improvement down payment to one thousand dollars or ten percent of the contract, whichever is less, at Business and Professions Code 7159.5, and Nevada's contractors board applies the same limit to pool contracts. Florida takes a different route, requiring a contractor who has taken more than ten percent to apply for permits within thirty days and start work within ninety days of the permits issuing.

Florida also writes the failure mode into its disciplinary statute. Section 489.129(1)(g) names as financial mismanagement the case where the percentage of work completed is less than the percentage of money collected. That is a pool build going wrong, described by a legislature.

The second exposure is the lien. A subcontractor or supplier the builder never paid can record a claim against the property even where the owner paid the builder in full, which is how one job gets paid for twice. California's board points to joint checks made out to the builder and the supplier together, and unconditional lien releases from everyone paid. Deadlines and forms are state law and differ: California runs a twenty-day preliminary notice, Florida a notice to owner under chapter 713.

How to choose

Pick the shell for the decade, not the install. Vinyl is cheapest going in and carries a liner replacement on a five to fifteen year clock. Gunite costs the most and adds resurfacing every seven to fifteen years. Fiberglass costs more than vinyl and asks the least afterward.

Get the excluded list in writing before comparing two quotes, because the quotes are otherwise not comparable. Fencing, decking, landscaping, lighting, the heater and the water to fill it are the usual omissions, and the fence is the one the permit will ask for.

Check the license at the level that issues one. In California, Florida, Nevada, Virginia and Arizona there is a pool classification to look up. In Texas there is nothing at state level, so the check is the city or county plus the electrical license held by whoever does the bonding.

Read the payment schedule against the build schedule. The question is whether the money collected at each stage tracks the work finished at that stage, which is the same test Florida uses to define mismanagement.

Ask how subcontractors and suppliers get paid, and what proof of that comes back. This is the part of the job an owner cannot see, and a lien recorded later attaches to the property rather than to the builder.

Expect the permit to take time. Angi puts permitting at two to six weeks and notes it sometimes runs to months, which is often the difference between a pool finished in spring and one finished in August.

Questions to ask before you sign

  • Which shell is this quote for, and what is the replacement or resurfacing interval on it?
  • What is excluded, in writing, and is the barrier among the exclusions?
  • What barrier does this jurisdiction actually require, and who pulls the permit?
  • What license do you hold, at which level, and who does the pool bonding and electrical?
  • What is the deposit, and how does each later payment map to a completed stage?
  • How do I get proof that your subcontractors and suppliers have been paid?
  • How long is permitting running here right now, and what is the completion date in this contract?
  • What happens if the excavation hits rock or a water table?

Common questions

What does an inground pool cost?

About $25,000 to $100,000 on HomeGuide's July 2025 data, at $80 to $250 a square foot. Angi's August 2026 figures are narrower and higher, $44,499 to $87,349 with a $65,909 average. Both are published here because the two disagree by roughly $20,000 at the low end and the gap is real.

Which is cheapest to own, concrete, fiberglass or vinyl?

Fiberglass, on annual cost. Angi puts yearly upkeep at $500 to $1,500 for fiberglass, $1,100 to $1,700 for vinyl and $2,700 to $4,000 for concrete. Vinyl is cheapest to install but carries a liner replacement every five to fifteen years, and concrete needs resurfacing every seven to fifteen.

Is a backyard pool covered by the federal pool safety law?

No. The Virginia Graeme Baker Pool and Spa Safety Act applies to public pools and spas, pools serving multi-unit housing, and federal government pools for service members. A single-family residential pool sits outside it, which is why the barrier rules that do apply are state and local.

Does a pool fence have to be 48 inches?

Only where the local jurisdiction adopted a code that says so. The 48-inch figure comes from section 305 of the 2018 International Swimming Pool and Spa Code, and the Consumer Product Safety Commission states inside its own barrier guidelines that they are not a standard and not mandatory. Check the city or county.

Is the fence included in the price?

Usually not. Fencing, decking, landscaping, lighting, the heater and the water to fill the pool are typically quoted separately from the shell, while the barrier is generally a condition of the permit.

Do pool builders need a license?

It depends on the state. California issues a C-53 Swimming Pool Contractor classification, Florida sets pool contracting in statute, Nevada has an A-10 classification, Virginia a POL specialty and Arizona several pool codes. Texas licenses no pool contractor and no general building contractor at state level, so the credential there is city or county.

How much can a builder ask for up front?

In California a home improvement down payment cannot exceed $1,000 or 10 percent of the contract, whichever is less, and Nevada applies the same limit to pool contracts. Most states set no cap. Florida instead requires a contractor who has taken more than 10 percent to apply for permits within 30 days and start work within 90 days of issue.

Can I end up paying for the same work twice?

Yes, through a mechanics lien. A subcontractor or supplier the builder never paid can record a claim against the property even where the owner paid the builder in full. Joint checks and unconditional lien releases are the usual defenses, and the deadlines are state-specific.

How long does a pool take to build?

Eight to twelve weeks for an inground pool on Angi's July 2026 figures. Permitting alone runs two to six weeks and sometimes months. A fiberglass shell drops in within a day or two of excavation, while gunite needs 30 days or more to cure.
