Hiring a pool or spa contractor without scrutinizing their contract and pricing structure is how homeowners end up hemorrhaging money on hidden fees and incomplete work. A vague estimate and handshake agreement might feel friendly, but they're recipes for disputes when the project goes sideways. Here's what to watch for before you sign.
Contracts Without Clear Scope of Work
The biggest red flag is a contract that doesn't spell out exactly what's included. "Pool renovation" means nothing—does it cover replastering, new tile, equipment replacement, or just surface cleaning? A legitimate contractor will list every service, material specification, and timeline in writing.
Ask for specifics like:
- Exact dimensions and depth of work areas
- Brand and model numbers of any equipment being installed
- Breakdown of labor hours vs. material costs
- Start date and projected completion date (with buffer days noted)
- Warranty terms on workmanship and parts
If the contractor resists putting these details in writing, that's your cue to get quotes elsewhere.
Pricing Red Flags That Scream Trouble
Quotes that seem impossibly cheap. A $2,000 pool resurfacing when competitors quote $4,500–$6,000 usually means corners will be cut or costs will balloon later. Cheap initial pricing often leads to change orders that double the final bill.
No itemization of costs. You should see labor, materials, permits, and disposal separated out. A single lump sum makes it impossible to spot inflated numbers. For example, a legitimate replaster job typically breaks down as: materials ($800–$1,200), labor ($1,500–$2,500), and permits ($100–$300).
Payment terms concentrated upfront. Asking for 50% or more before starting work is standard in construction, but anything over 75% upfront is risky. The payment schedule should align with project milestones: 30–40% to start, 30% at mid-point, and 30–40% upon completion.
No mention of permits or warranty. Local jurisdictions often require permits for significant pool work. If the contractor doesn't mention them, they may be planning to skip them—leaving you liable for fines and complications when selling your home. A credible contractor warranties their workmanship for at least one year.
Hidden Costs and Change Orders
Change orders are realistic in pool projects—unexpected damage beneath old plaster or equipment failure happens. But watch out for vague language that lets contractors add charges without your approval.
Your contract should include:
- A clause requiring written approval (and pricing) for any work beyond the original scope
- A buffer line-item (typically 5–10% of the total) for contingencies, but capped
- Clear hourly rates if hourly work becomes necessary
- A deadline for cost discussions (e.g., "any change order must be presented within 48 hours of discovery")
Red Flags in Insurance and Liability
Ask for proof of liability insurance and workman's compensation coverage. A contractor without insurance is betting you'll pay if someone gets hurt on your property. Request a certificate of insurance listing your address, and verify it's current—some contractors show expired papers.
If they can't or won't provide it, move on immediately.
Timeline and Completion Concerns
Overly optimistic timelines are another warning sign. A basic pool cleaning takes 2–4 hours; equipment repairs range 1–3 days; a full resurface takes 7–10 days (longer if tile work is involved). If a contractor promises a major project in a weekend, they're either inexperienced or planning to rush through it.
The contract should also specify what happens if they miss deadlines—penalties for delays protect you from contractors who double-book jobs.
How to Protect Yourself
Before signing anything, get at least three written quotes. Use Mercoly to compare and find trusted pool and spa services providers in one place, so you can easily review multiple contractors' credentials and pricing side-by-side.
Don't rely on email exchanges—insist on formal written contracts. Review everything with the same rigor you'd use for a home purchase, because work on your pool or spa is a significant investment.
Frequently Asked Questions
Q: What's a typical warranty for pool replastering, and should I ask for longer? Most contractors offer a one-year warranty on plaster work and 2–3 years on equipment. A three-year plaster warranty is reasonable and worth negotiating if the contractor's track record supports it.
Q: How do I know if a contractor is licensed and insured in my state? Check your state's contractor licensing board website (usually under the Secretary of State or Department of Consumer Affairs) and ask to see a current insurance certificate with your property listed as an additional insured.
Q: Can I hold back final payment until I'm happy with the work? Yes—this is standard practice. Retain 10–15% until final inspection and sign-off, giving you leverage to address defects before releasing the full payment.
