How much does it cost to remove an old pool and fill in the hole in Ottawa?

Removing an old inground pool and filling in the hole in Ottawa costs between $8,000 and $25,000, with most residential projects falling in the $12,000 to $18,000 range depending on pool size, pool type (vinyl liner, fibreglass, or concrete/gunite), accessibility for heavy equipment, disposal requirements, and whether you choose a partial fill (abandonment) or full removal. Above-ground pool removal is considerably less — typically $500 to $2,000 — since it involves disassembly rather than excavation.

There are two approaches to inground pool removal in Ottawa: partial removal (also called pool abandonment or fill-in) and full removal. The choice between them affects cost significantly and has long-term implications for what you can do with the land afterward.

Partial removal is the more common and less expensive option, costing $8,000 to $15,000 for a standard 14-by-28-foot inground pool. In a partial removal, the contractor drains the pool, punches drainage holes through the bottom of the pool shell (every 2 to 3 feet across the floor), removes the top 18 to 36 inches of the pool walls, and then fills the cavity with a combination of demolition debris from the walls and clean fill material. The fill is compacted in lifts (layers) to minimize future settling, and the top 12 to 24 inches are filled with topsoil for grading and grass. This method is faster (typically 2 to 4 days) and generates less waste for disposal. The disadvantage is that a partially removed pool creates an area that will settle over time — you can plant grass, garden beds, or install a patio, but the City of Ottawa will not issue a building permit for a permanent structure (like a house addition, garage, or new pool) over a partially removed pool without a geotechnical assessment confirming the fill is adequately compacted.

Full removal costs $15,000 to $25,000 or more and involves completely excavating the pool shell, removing all concrete, steel, fibreglass, and plumbing, and backfilling the entire cavity with engineered fill compacted to construction-grade standards. The excavation generates a massive volume of waste material — a typical 14-by-28-foot concrete pool produces 15 to 25 tonnes of rubble that must be hauled away. Disposal of concrete and steel at Ottawa-area landfills and recycling facilities costs $80 to $150 per tonne, adding $1,200 to $3,750 in disposal fees alone. Clean fill material to replace the excavated soil and rubble costs $20 to $35 per cubic metre delivered, and a full pool cavity requires 40 to 80 cubic metres of fill, costing $800 to $2,800 for material plus delivery. Full removal takes 4 to 7 days and requires a large excavator (20-tonne class), multiple dump trucks, and a compaction roller — equipment that needs clear access to the backyard, which is a challenge on many Ottawa lots with narrow side yards.

Pool type significantly affects removal cost. Vinyl liner pools have thin steel or polymer walls that are relatively easy to cut, collapse, and remove — the cheapest to demolish. Fibreglass pools are a single large shell that must be broken into pieces with an excavator or, if still intact, craned out in one piece (rare, but possible if access allows). Concrete or gunite pools have thick, steel-reinforced walls and floors that require hydraulic breaker attachments on the excavator to demolish — the most labour-intensive and expensive to remove. A concrete pool removal costs 30 to 50 percent more than a comparable vinyl liner pool removal.

The City of Ottawa requires a demolition permit for pool removal, which costs $100 to $300. The permit ensures the work meets Ontario Building Code requirements for backfilling and grading. You must also call Ontario One Call (1-800-400-2255) before any excavation to locate underground utilities — a free service that is legally required. Pool removal contractors working in Ottawa's urban and suburban areas must also comply with the city's noise bylaw (Bylaw 2017-255), which restricts construction noise to weekdays 7 AM to 7 PM and Saturdays 9 AM to 6 PM, with no construction noise on Sundays or statutory holidays. Given the heavy equipment involved in pool demolition, informing your neighbours before work begins is both courteous and practical — excavators, dump trucks, and concrete breakers are extremely loud.

Ottawa's clay soils create additional challenges for pool removal. The Leda clay and Champlain Sea clay that underlie much of the city — particularly in Barrhaven, Kanata, Nepean, and Orleans — have poor drainage and tend to hold water. When a pool shell is removed and the cavity is backfilled, the surrounding clay can channel groundwater into the fill area, creating a perpetually wet zone that settles unevenly and can flood neighbouring basements if grading is not done correctly. A competent removal contractor will install a French drain or drainage layer at the bottom of the filled cavity to manage groundwater, adding $1,000 to $2,500 to the project but preventing water problems for years to come.

Asbestos is a potential concern in concrete pools built before 1985. Some older Ottawa pool decks and coping used materials containing asbestos fibres, which require specialized abatement procedures for removal. If asbestos is found, a licensed abatement contractor must handle the removal at a cost of $2,000 to $8,000 depending on the quantity and type of asbestos-containing material. An asbestos assessment before demolition begins costs $300 to $500 and is strongly recommended for any pool built before the mid-1980s.

Partial vs. Full Removal: Making the Right Choice

Choose partial removal if you plan to landscape over the pool area with grass, gardens, or a surface-level patio and have no plans to build a structure on the site. Choose full removal if you intend to build anything on the site in the future, if you are selling the property and want to avoid disclosure complications, or if you simply want the pool completely gone with no trace. Ottawa real estate lawyers generally advise full removal before listing a property for sale, as a partially removed pool is a material fact that must be disclosed and can complicate buyer financing if the lender's appraiser flags potential settling issues.
