Build one comparison sheet

Put every proposal into one row-by-row worksheet before comparing totals. Record pool dimensions and depth, shell and finish, pumps and sanitation, electrical and plumbing, decking, drainage, fencing, permits, access restoration, startup, cleanup, and warranty. A blank cell is a question, not a free inclusion.[3]

  • Separate fixed prices from allowances and owner-supplied work.[3]
  • Ask each bidder to price the same equipment model or an explicitly equivalent model.

Verify the contractor, not just the proposal

Confirm the business identity, license status where licensing applies, insurance, recent references, and who will supervise the job. The Federal Trade Commission recommends checking credentials and references and being cautious about contractors who pressure you to decide immediately or demand full payment up front.[1][2]

  • Use the licensing authority's own lookup rather than a badge or screenshot supplied by the bidder.[2]

Resolve price and schedule risk in writing

Ask what can change the price, how changes are approved, what triggers each payment, and what happens if inspections or materials delay the work. Do not rely on verbal promises. The contract should identify the work, price, payment schedule, estimated dates, and warranties clearly enough that both sides can tell when a milestone is complete.[1][3]

  • Compare the cash-flow schedule as carefully as the total price.[1]
  • Require signed change orders before changed work begins.[3]

Questions people ask before choosing a builder

Should I automatically reject the highest pool bid?

No. First normalize the scope. A higher bid may include permits, premium equipment, access restoration, cleanup, or warranty coverage that a lower bid excludes. Compare the final documented scope and risk, not only the headline total.[3]

How many pool bids should I get?

There is no universal legal number, but multiple detailed bids make omissions and unusual terms easier to spot. The FTC advises getting written estimates from several contractors and comparing the same work, materials, and completion dates.[1]
