What is the average estimate for exterior rendering on a bungalow in Nepean?

Exterior rendering on a bungalow in Nepean typically costs between $12,000 and $25,000 for a full-home application, with the average sitting around $15,000 to $20,000. Bungalows are generally more affordable to render than two-storey homes because most of the work can be done from ground level or low scaffolding, which significantly reduces labour costs.

Why Nepean Bungalows Are Ideal Candidates for Rendering

Nepean has one of Ottawa’s largest concentrations of bungalows, built primarily in the 1960s through 1980s in neighbourhoods like Barrhaven South, Craig Henry, Bells Corners, and Centrepointe. Many of these homes have original brick, aluminum siding, or a combination that’s showing its age. Exterior rendering — whether traditional stucco, acrylic, or a modern render system — can completely transform the look of these homes while adding genuine weather protection.

A typical Nepean bungalow has 900 to 1,400 square feet of exterior wall area. At $10 to $17 per square foot for a quality rendering system (including preparation, materials, and labour), the math works out to the range above. Here’s how the costs typically distribute:

Preparation and substrate work: 25 to 35% of total cost. This includes any removal of existing cladding, installation of building paper or house wrap, metal lath or insulation board, and control joints. For bungalows with existing brick, rendering can sometimes go directly over the brick after proper preparation, saving the cost of removal.

Rendering application: 40 to 50% of total cost. This covers the actual material and skilled labour for applying the rendering coats. A standard three-coat system takes 3 to 5 days for a bungalow, plus curing time between coats.

Finishing details: 15 to 25% of total cost. Window surrounds, corners, base trim, and integration with soffits and fascia. These details make or break the final appearance.

For Nepean specifically, many bungalows have generous eave overhangs (12 to 18 inches), which is actually great news for rendered walls. The overhang protects the upper portion of the wall from direct rain exposure, which extends the life of the rendering and reduces maintenance needs. Homes with minimal overhangs will need more robust waterproofing in the rendering system.

The energy efficiency angle is worth considering for Nepean bungalows, many of which have original insulation levels well below current code. Adding an insulated rendering system (like EIFS) with 1.5 to 3 inches of rigid foam can bring your walls closer to modern performance standards. The Greener Homes Grant and other energy efficiency programs may offer rebates that offset some of this cost — it’s worth checking current program availability before starting your project.

A City of Ottawa building permit is typically required when applying new exterior rendering systems, particularly if insulation is being added or the building envelope is being modified. The permit ensures the work meets Ontario Building Code requirements for moisture management, fire safety, and structural attachment. Your contractor should handle the permit application, but confirm this upfront.

Timing recommendation for Nepean: book your contractor in January or February for a spring start. The best stucco crews in Ottawa fill their schedules early, and a bungalow is an attractive project for contractors because the lower height means faster, safer work. Early booking often gives you better scheduling flexibility and sometimes better pricing.
