How to read and compare inground pool quotes

Compare the same scope before comparing prices

Start by comparing the written scope, inclusions, allowances and exclusions for the same pool project.

So the first job is to make every bidder answer the same question: ask each one to quote against the same written scope of work, meaning size, depth, decking, fencing and permit handling, before comparing price. Write that scope yourself, or take the most complete bid you have received and ask the others to price the same list. Only then does a difference in price tell you something about the builder rather than about the paperwork.

Which costs should the written bid itemize?

Request a written breakdown, then compare the listed labor, materials, equipment, allowances and exclusions before comparing prices.

• Excavation and site work, including haul-off of spoils and any grading or drainage correction.
• The shell itself, with size, depth profile and finish specified.
• Utility rough-ins: electrical to the equipment pad, gas if a heater is planned, and the plumbing runs.
• Equipment and features: pump, filter, heater, lighting, any automation and an integrated spa if one is planned, by model or specification.
• Decking and coping, with the material and the square footage stated.
• Fencing or another code-compliant barrier, if it is in the bidder's scope at all.
• Permits, engineering and inspection coordination, or a note that they are excluded.
• Landscape restoration once the machines leave.

A line that says pool package with a single figure tells you almost nothing; ask for the list. A contractor who can itemize has planned the job, and the list itself becomes the scope you hand to the next bidder.

Compare fiberglass base-package and full-project quotes

Illustrative example: one written quote lists the pool and equipment but excludes decking and leaves drainage pending; another defines those scopes. Compare the base-package and finished-project amounts only after each line is written as included, an allowance, excluded, owner-provided, or subject to a site condition.

How do you verify who you're hiring?

Check the applicable local and state requirements and request insurance verification before signing a contract or making a payment. Licensing requirements vary by location.

Insurance verification is a document, not a verbal assurance. Ask for a current certificate of insurance issued to the company that will be on your property, what it covers, and how any excavation or electrical subcontractor is covered. A builder who does this work every week will have the paperwork ready, and the speed of the answer is itself information.

What should you check in a lower bid?

A lower bid may reflect a different scope, allowance or exclusion. Compare those details with the other bids before deciding whether the prices describe the same project.

Compare exclusions, allowances, site-condition assumptions and the written change process. Ask what triggers a change, which line it affects, and how work and approval are recorded before it begins. A lower total can reflect a different scope, selection, quantity, responsibility, or unresolved condition.

What terms belong in writing before you sign?

Compare the proposed filtration equipment, plaster quality and what the applicable warranty covers. Warranty coverage and terms depend on the written warranty that applies to each bid.

The payment schedule shows how a contractor manages risk. A modest deposit followed by draws tied to milestones, such as excavation complete, shell set, plumbing and electrical passed inspection, deck finished and the pool holding water, is the pattern to look for. A large upfront payment with no milestones puts the risk on you. Ask how change orders are priced and approved, and who is responsible if the village inspection requires rework.

If financing is part of the plan, the Consumer Financial Protection Bureau's consumer guides explain the general differences between a home-equity loan, a HELOC and a personal installment loan, including that each may carry its own fees, so the total you compare against a bid is the cost of the money as well as the cost of the pool.

How should you compare a full-project bid?

Compare the written labor, materials, allowances and exclusions included in the proposed full-project amount.
