What should I budget for parging the exposed foundation of a raised bungalow in Ajax?

For a raised bungalow in Ajax, you should budget between $3,000 and $7,000 for full foundation parging, with most projects falling in the $4,000-$5,500 range. Raised bungalows have significantly more exposed foundation than standard homes — typically 3 to 4 feet of visible concrete or block above grade on all four sides — which increases both the total square footage and the labour required.

A typical raised bungalow in Ajax with a 1,200 square foot footprint might have 250 to 400 square feet of exposed foundation surface, depending on grading and how much of the basement sits above the soil line. At GTA pricing of $8-$12 per square foot for traditional Portland cement parging or $12-$18 per square foot for polymer-modified parging, the material and labour costs add up quickly. For Ajax specifically, pricing tends to sit slightly below Toronto core prices but above smaller Ontario markets — you're looking at the lower-to-mid range of GTA rates because contractors based in Durham Region have lower overhead than downtown Toronto operations, but Ajax is still very much within the GTA labour market.

The condition of the existing foundation is the biggest variable in your budget. Many Ajax raised bungalows were built in the 1960s through 1980s with concrete block foundations, and the original parging — if it was applied at all — is often failing badly. If your foundation just needs surface prep and a fresh two-coat application of parging, you're looking at the lower end of that range. If the existing parging needs to be fully removed (chipped off, old material hauled away, surface cleaned and prepped), that removal work adds $3-$6 per square foot to the project cost. Complete removal and re-parging of a raised bungalow foundation can push costs toward $5,000-$7,000.

Polymer-modified parging is the smart choice for Ajax. The Durham Region sits on heavy clay soils that hold moisture against foundation walls for extended periods, and Ajax's proximity to Lake Ontario increases humidity and the total number of freeze-thaw cycles. Traditional Portland cement parging applied to a raised bungalow with 3-4 feet of exposure is fighting an uphill battle against all that moisture and temperature cycling. The extra $4-$6 per square foot for polymer-modified parging — roughly $1,000-$2,000 more on a typical raised bungalow — pays for itself by lasting 20-30 years instead of 8-12 years. When you factor in the cost of re-doing failed traditional parging in a decade, polymer-modified is actually cheaper over the life of the home.

Before any parging work begins, address grading and drainage. Ensure soil slopes away from the foundation at a minimum of 6 inches over the first 6 feet, extend all downspouts at least 6 feet from the foundation, and check that window wells have covers and proper gravel drainage. These steps cost very little but dramatically extend the life of your new parging. Also confirm that your contractor carries WSIB coverage — all masonry contractors working on residential projects in Ontario must have it, and homeowners can be held personally liable for workplace injuries if the contractor is uninsured. Get at least three written quotes that specify the parging material (traditional vs. polymer-modified), number of coats, whether bonding agent is included, and the curing plan. A reputable contractor will schedule the work during the safe parging window — mid-April through mid-October when temperatures stay consistently above 5 degrees Celsius day and night.
