How much does it cost to remove and replace a damaged pool skimmer in Ottawa?

Removing and replacing a damaged pool skimmer in Ottawa typically costs $800 to $2,500 for a standard residential inground pool, including the new skimmer unit, labour, plumbing connections, and patching the surrounding deck or coping. The cost depends primarily on whether the skimmer body itself is cracked, the throat (the opening where it meets the pool wall) is damaged, or the underground plumbing connected to the skimmer has failed — each scenario involves a different scope of work.

A skimmer body replacement is the most straightforward repair. The skimmer box — the plastic housing that sits behind the pool wall and holds the basket — costs $150 to $400 for a quality replacement unit from manufacturers like Hayward, Pentair, or Waterway. Labour to remove the old unit, set the new one in a mortar bed, reconnect the plumbing, and seal the joint to the pool wall runs $500 to $1,200 in Ottawa. The work requires the pool water level to be dropped below the skimmer opening, but the pool does not need to be fully drained. Most Ottawa pool technicians can complete a straightforward skimmer body swap in one day.

The complication that drives costs higher in Ottawa is frost damage to the skimmer throat and surrounding concrete. Ottawa's freeze-thaw cycle is particularly punishing to skimmers because water trapped in the skimmer throat — the transition piece between the pool wall tile line and the skimmer body — expands as it freezes and cracks both the throat fitting and the concrete or gunite around it. Repairing frost damage to the surrounding pool wall and coping adds $500 to $1,500 to the project because the contractor must chip out damaged concrete, rebuild the structural area with hydraulic cement or fresh gunite, and then re-tile or re-plaster to match the existing pool finish.

Preventing repeat skimmer frost damage is critical for Ottawa pool owners. The reason skimmers crack in the first place is almost always improper winterization. During fall closing, the water level should be lowered to 10 to 15 centimetres below the skimmer opening, a gizzmo (a hollow plastic plug) should be threaded into the skimmer basket hole to absorb ice expansion, and antifreeze should be poured into the skimmer line after it has been blown clear with compressed air. If your pool closing company skips any of these steps, the water remaining in and around the skimmer freezes, expands, and cracks the skimmer body, throat, or both. When getting your skimmer replaced, confirm that your closing procedure addresses all three protection measures.

The plumbing connected to the skimmer is another potential cost escalator. Each skimmer has at least one suction line running underground to the pump — and some Ottawa pools have skimmers with two ports (a main suction line and an equalizer line connected to the main drain). If the underground pipe within the first metre or two of the skimmer has cracked from frost heave, the contractor needs to excavate behind the skimmer, cut out the damaged section, and splice in new PVC. This excavation work adds $500 to $2,000 depending on what is above the pipe — bare soil is cheap to dig through, while concrete decking or interlock pavers require demolition and restoration.

For Ottawa pools with multiple skimmers, replacing just one creates a decision point about the others. Most residential pools in Ottawa have one or two skimmers. If one has failed due to frost damage, the other has experienced the same conditions and may be developing invisible hairline cracks that will fail next winter. Replacing both skimmers simultaneously costs roughly 40 to 50 percent less than doing them sequentially because the mobilization, water lowering, and equipment setup happen once instead of twice. Ask your contractor to inspect the second skimmer carefully and provide an honest assessment of its remaining lifespan.

The type of pool affects skimmer replacement complexity and cost. Concrete (gunite/shotcrete) pools, which are the most common inground pools in Ottawa's established neighbourhoods like Rockcliffe Park, The Glebe, and Westboro, have skimmers set in concrete that must be chiselled out and rebuilt. Vinyl liner pools have skimmers that bolt through the pool wall with a gasket seal — these are simpler to replace (typically $600 to $1,500 all-in) but require that the liner be carefully peeled back from the skimmer face plate without tearing it. If the liner is older than 10 years, the vinyl around the skimmer opening may be brittle, and peeling it back risks cracking it — potentially turning a skimmer replacement into a liner replacement at an additional $4,000 to $7,000.

Timing your skimmer replacement matters for both cost and convenience in Ottawa. The ideal time is early spring, before pool opening season, when contractors have availability and can complete the work before you lose swimming days. Mid-summer emergency replacements cost 15 to 25 percent more due to urgency scheduling and the need to work around a pool that the homeowner wants operational as quickly as possible. If you notice a cracked skimmer during fall closing, book the repair for the following spring rather than attempting a cold-weather fix — concrete and sealant products do not cure properly below 10°C, and Ottawa's October temperatures are already marginal for these materials.
