Questions to Ask a Pool Contractor Before You Sign

For homeowners getting bids on a new pool or a major renovation. These 20 questions pull the vague parts of a pool proposal into the open: exclusions, excavation surprises, draw schedules, equipment brands and warranty terms.

20 questions, each with the reason to ask it · includes a conversation guide

The questions

Open any question to see why it works.

  1. 1

    Are you licensed to build pools in this state, and can I see your license number and a current certificate of insurance?

    Many states license pool construction separately from general contracting, and the certificate should name your address as the job site. A contractor who sends a screenshot instead of a certificate straight from the insurer is a bad sign.

  2. 2

    How many pools did you build last year, and how many are in progress right now?

    This is the fastest way to spot a company that has sold more jobs than its crews can dig. A builder running twenty simultaneous projects with one excavation crew will leave your yard open for weeks.

  3. 3

    Which phases does your own crew handle, and which ones go to subcontractors?

    Almost every pool involves subs for shotcrete, plumbing, electrical and plaster, so the honest answer is a list, not a claim that everything is in house. It also tells you who to expect in your yard and who your builder can actually schedule on short notice.

  4. 4

    Can I see a pool you are building right now and one you finished two or three years ago?

    The active site shows you how they treat a yard mid build, including spoil piles, trash and safety fencing. The older pool shows whether the plaster mottled, the coping shifted or the deck cracked once the ground settled.

  5. 5

    What construction type are you recommending for my yard, and why that over the alternatives?

    Gunite, fiberglass and vinyl liner pools differ in cost, lead time, shape freedom and long term resurfacing bills. A builder who only sells one type should still be able to explain honestly where it is the weaker choice.

  6. 6

    What is included in this bid, and what is deliberately excluded?

    Pool bids routinely leave out decking beyond a small border, the code required barrier, gas line runs, electrical panel upgrades, water to fill, and repair of torn up lawn and irrigation. Getting the exclusions in writing is how you stop a low bid from becoming the expensive one.

  7. 7

    Who pulls the permits, and what does my local code require for barriers, gates, alarms and setbacks?

    Barrier and setback rules vary by city and are often the hidden cost that arrives after the pool is wet. A builder who knows your jurisdiction will answer with specifics like fence height, gate swing and self latching hardware.

  8. 8

    What did the site evaluation or soil test show, and how does that change the design?

    Expansive clay, a high water table, fill dirt and shallow bedrock all change steel schedules, wall thickness and whether you need a hydrostatic relief valve. A builder who has not looked at soil is pricing a guess.

  9. 9

    If you hit rock, groundwater or a buried utility during excavation, how are the extra cost and delay handled?

    Excavation is the single most common source of change orders, and most contracts push that risk to you. Ask for the unit price per yard of rock removal and the dewatering rate now, before it is leverage.

  10. 10

    How will the excavator and concrete equipment reach the backyard, and who repairs the access route, irrigation lines and sod?

    Access often means removing fence panels, driving over a driveway or cutting through a neighbor's easement. Answers here reveal whether the yard restoration is your problem or theirs.

  11. 11

    What is the payment schedule, and which completed milestone triggers each draw?

    Draws should follow finished work such as excavation, steel and plumbing, shotcrete, tile and coping, deck and plaster, not the calendar. A large deposit before anything is dug leaves you with no leverage if the crew stops showing up.

  12. 12

    Will you provide signed lien waivers from your subcontractors and suppliers with each payment?

    If your builder collects a draw and does not pay the plaster crew, that crew can lien your house even though you paid in full. Lien waivers are the only routine protection against paying twice.

  13. 13

    Exactly which equipment are you installing, including pump, filter, heater, sanitizer and automation, with brands and model numbers?

    Proposals that say variable speed pump and cartridge filter with no models let a builder substitute the cheapest option later. Model numbers also let you look up filter square footage, heater BTUs and whether parts are locally serviceable.

  14. 14

    How many working days do you expect crews to be on site, and what are the normal gaps between phases?

    Pool builds are mostly waiting: inspections, shotcrete cure, deck sequencing. A realistic answer separates total calendar weeks from actual work days and tells you where the schedule usually slips.

  15. 15

    Once construction starts, who is my single point of contact, and how do they communicate progress?

    The salesperson who wins the job frequently disappears at excavation. You want a named superintendent, a phone number and a stated update rhythm rather than a promise to stay in touch.

  16. 16

    How are change orders priced and approved, and will you show me one from a recent job?

    Seeing a real change order tells you whether they document scope and cost before work happens or hand you a surprise at the end. It also shows whether markup on changes is disclosed.

  17. 17

    What are the separate warranty terms for the shell, the interior finish, tile and coping, the equipment and your labor, and what voids each one?

    Pool warranties are stacked, not single: a structural warranty may run decades while plaster runs a few years and equipment is covered by the manufacturer. The voiding conditions matter most, because improper water chemistry is the usual escape hatch.

  18. 18

    What happens during startup after the pool is filled, and who manages water chemistry for the first 30 days?

    New plaster needs daily brushing, controlled chemistry and a delay before salt or a heater runs, and mistakes here cause permanent staining and scale. Confirm whether startup is included, subcontracted or handed to you with a pamphlet.

  19. 19

    Based on pools you have built near me, what should I expect to spend each month on electricity, gas, water and chemicals?

    Operating cost is where pool owners get blindsided, and it varies hugely with heater use, pump speed and evaporation in your climate. A builder with local history can give ranges, and a vague answer suggests they do not stay in touch with past customers.

  20. 20

    If I find a defect two years from now, who do I call, and can you give me a customer whose warranty claim you actually handled?

    Every builder promises service; few can produce a reference for a problem they fixed on their own dime. This question tests whether the company has a service department or just a sales team.

Hiring a Pool Contractor Without Regret

Practical guidance for the conversation itself.

Before you collect bids

Verify the license and the complaint history separately

Look the company up on your state contractor board for active license status, bond, and any disciplinary actions, then search the business name plus the owner's name for lawsuits. Pool builders often close one entity and reopen under a new name, so a company founded last year run by a twenty year veteran deserves a direct question about the previous entity.

Get bids on the same scope, not the same price

Write down size, depth, construction type, finish, decking square footage, and equipment before you call anyone. Otherwise you will compare a 400 square foot deck against a 120 square foot deck and conclude one builder is cheaper.

Budget for the parts that are never in the pool bid

Set aside money for the code required barrier, landscaping repair, outdoor electrical, a gas line if you want a heater, furniture, and the first year of chemicals and higher utility bills. On many projects this adds fifteen to thirty percent on top of the pool itself.

What the contract must say in writing

  • Total price with an itemized allowance for tile, coping, decking and interior finish, plus what happens if you exceed each allowance
  • A written exclusions list: fill water, barrier, electrical panel work, gas line, irrigation and sod repair, tree removal, retaining walls
  • Payment draws tied to completed milestones, with the final payment held until the punch list is signed off
  • Unit prices for rock removal, dewatering and over excavation of unstable soil
  • Named equipment brands and model numbers, with a clause requiring your written approval for any substitution
  • Start date, substantial completion date, and what happens if the job stalls with no crew on site for a set number of days
  • Separate warranty terms and durations for shell, finish, tile and coping, deck, plumbing, and equipment
  • Lien waivers from subcontractors and suppliers delivered with each draw

Red flags during the sales visit

A large deposit before permits or excavation

Some states cap pool deposits by statute. A request for thirty or forty percent up front, especially with a discount for paying cash today, is how underfunded builders finance the job they are already behind on.

A price quoted before anyone looked at your soil or access

A firm number produced at the kitchen table without a site walk means the risks are still unpriced, and they will come back to you as change orders.

References that are all brand new pools

Fresh plaster always looks good. Insist on at least one customer from three or more years ago, because that is when structural cracks, plaster failure and settled decking show up.

Vagueness about who does the plaster

Interior finish is the most visible and most warranty disputed part of the pool. If your builder cannot name the plaster crew and how many pools they do a week, you cannot evaluate the finish you are buying.

The phases to track once work starts

  • Layout and excavation: confirm the shape and elevation staked in your yard match the plan before digging
  • Steel and plumbing: photograph rebar spacing and plumbing runs, and ask for the pressure test result
  • Shotcrete or gunite: watch for proper cure watering in the days after, since a dry cure weakens the shell
  • Tile, coping and masonry: check waterline tile level and grout lines while the crew is still on site
  • Decking: verify expansion joints and slope away from the pool so runoff does not drain into it
  • Interior finish and fill: fill continuously without stopping, then follow the startup brushing and chemistry schedule
  • Startup and orientation: get a walkthrough of the equipment pad, plus written instructions and all manuals and warranty registrations
