A quick rule of thumb: the homeowners who avoid problems are the ones who get everything in writing, verify licensing and insurance before work starts, and never rely on a verbal promise for anything that matters. If a detail is important enough to ask about, it is important enough to have in the written quote or contract.

Pool service failures manifest in a range of ways — from a pool that turned green under weekly service, to freeze damage from an inadequate closing, to equipment that failed prematurely from incorrect chemistry. Here’s how to respond to each.

For Chemistry Failures (Algae, Damage from Imbalanced Water)

A pool surrounded by rocks and gravel Green pool under ongoing service: If your pool has developed a significant algae bloom while receiving regular professional service, the chemistry was not being managed correctly. Step 1: Get an independent water test. Take a water sample to a pool supply store for a comprehensive water test — or hire a different service company for an assessment visit. This gives you an objective picture of the current chemistry state. Step 2: Request the service records. Ask the service company for all visit records — what was tested, what results were recorded, what was added at each visit. These records tell you whether testing was actually occurring and whether the chemistry management was appropriate. Step 3: Contact the company in writing describing the problem, attaching the independent test results, and requesting a remediation plan and explanation. Liner or surface damage from chemistry: If liner fading, etching, or other surface damage appears that you believe is attributable to chemistry management, the independent water test history and service records are the evidence. Document all visible damage with photographs.

For Freeze Damage After Closing

Black and white photo of a neglected empty swimming pool with debris. Freeze damage — cracked fittings, split pipes, damaged heat exchanger — is the most expensive pool service failure. It’s also the most clearly attributable to the service company if the closing was done by a professional. Step 1: Document all damage immediately. Photograph everything before any repairs are made — cracked fittings, split pipes, damaged equipment. Step 2: Get a written damage assessment from an independent pool service company describing what failed and the likely cause. Step 3: Contact the original service company in writing describing the damage and requesting they cover the cost of repair, as the damage is attributable to an inadequate closing. Step 4: If the company disputes responsibility: Ask them to provide documentation that the lines were blown out and the heater was drained during the closing. If they cannot provide this, you have strong grounds for the claim.

For Equipment Damage from Incorrect Service

If pool equipment has failed prematurely and you believe incorrect service or chemistry management was the cause (e.g., a pump seal destroyed by corrosive water, a heat exchanger damaged by low pH), follow the same process: document, get an independent assessment, contact the company in writing.

General Process

File complaints if the company doesn’t respond or disputes the claim:
  • Your local consumer protection office (consumerprotectionontario.Ca): For misrepresentation or failure to honor service obligations
  • Pool and Hot Tub Alliance (PHTA): If the company holds PHTA certifications, a complaint through the association is possible
  • Better Business Bureau: Public complaint record
  • Small claims court: For disputes under $35,000
