Westboro is one of Ottawa's most desirable and architecturally diverse neighbourhoods, with homes ranging from 1920s-era bungalows and two-storeys to mid-century ranches and modern infills. This mix means window replacement in Westboro isn't one-size-fits-all — each home type has different window sizes, styles, and replacement considerations.
Westboro is one of Ottawa's most desirable and architecturally diverse neighbourhoods, with homes ranging from 1920s-era bungalows and two-storeys to mid-century ranches and modern infills. This mix means window replacement in Westboro isn't one-size-fits-all — each home type has different window sizes, styles, and replacement considerations. Windows are the #1 source of energy loss in older Westboro homes. Single-pane and early double-pane windows from the 1960s–1990s leak heated air in winter and let heat in during summer. Replacing these windows with modern triple-pane, low-E, argon-filled units can reduce heating and cooling costs by 15–25% — a significant savings given Ottawa's extreme temperature swings. Beyond energy efficiency, window replacement in Westboro dramatically improves curb appeal. In a neighbourhood where home values range from $600,000 to over $1.5 million, quality windows contribute directly to property value. Real estate agents consistently report that new windows are among the top 3 features Westboro buyers evaluate. Noise reduction is another major benefit for Westboro homeowners. Homes along Richmond Road, Scott Street, or near the Transitway experience significant traffic noise. Triple-pane windows with laminated glass reduce exterior noise by 25–35 decibels compared to single-pane windows.
Window costs in Westboro are influenced by the neighbourhood's architectural diversity and the premium quality expectations of its housing market. Vinyl windows: $500–$1,000 per window installed. Best value for standard-sized windows. Modern vinyl frames are slim, durable, and available in colours beyond white (black, grey, and wood-grain finishes are popular in Westboro). Energy-efficient with no maintenance required. Fiberglass windows: $800–$1,600 per window installed. The growing favourite for Westboro homes. Fiberglass frames are stronger than vinyl, paintable, and have similar thermal expansion to glass (reducing seal failures in Ottawa's climate). Brands like Fibertec (Canadian-made) and Marvin offer premium fiberglass options. Aluminum-clad wood windows: $1,200–$2,500+ per window installed. Premium choice for Westboro's higher-value homes and heritage properties. Wood interior for warmth and character; aluminum exterior for weather protection. Brands like Marvin, Andersen, and Loewen are popular choices. Full-home replacement costs for a typical Westboro home (15–20 windows): Vinyl: $10,000–$18,000. Fiberglass: $14,000–$28,000. Aluminum-clad wood: $22,000–$45,000. Bay and bow windows, a common feature in Westboro homes, cost $2,500–$6,000+ per unit installed due to their size and structural requirements. Westboro's character homes often have non-standard window sizes. Custom-sized windows add 15–30% to the cost compared to standard sizes, but are necessary to maintain the home's architectural integrity.
Parts of Westboro fall within or adjacent to heritage conservation districts. If your home is designated heritage or in a heritage overlay zone, window replacement must comply with the City of Ottawa's Heritage Conservation District Plan. This typically means: Maintaining original window proportions and sightlines. You can replace the window unit but the opening size and grid pattern should match the original design. Using appropriate materials. In heritage properties, wood or aluminum-clad wood windows are generally required for street-facing elevations. Vinyl may be permitted for rear or non-visible windows. Heritage permit requirement. Heritage-designated homes need a heritage permit (in addition to any building permit) before window replacement. This process takes 4–8 weeks and requires detailed plans showing the proposed windows. Even if your Westboro home isn't heritage-designated, maintaining its character is important for neighbourhood consistency and resale value. A 1940s Cape Cod with modern casement windows looks incongruous. Work with an installer who understands architectural styles and can recommend windows that complement your home's era. Simulated divided lites (SDL) — grids that sit on both sides of the glass with a spacer bar between the panes — provide a traditional appearance while maintaining modern thermal performance. They're strongly recommended for character homes over flat grilles (which look obviously fake) or true divided lites (which reduce energy efficiency).
Experience with Westboro housing types: Ask potential installers how many Westboro projects they've completed. Installers experienced with the neighbourhood understand the common framing types, brick veneer details, and architectural styles. Ask for Westboro references you can visit. Full-service vs window-only: Some companies only supply and install windows. For Westboro's older homes, you want an installer who also handles interior and exterior trim, capping, caulking, and any wall repair needed around the opening. Sloppy finishing around new windows undermines the entire project. Brick mould and exterior trim: Many Westboro homes have brick exteriors. Window installation in brick requires careful removal of the existing frame, proper shimming and insulation of the rough opening, and precise caulking and trim work. Improper installation in brick causes water infiltration that's expensive to repair. Installation method — full frame vs insert: Full-frame installation removes the entire window including the frame, allowing inspection and insulation of the rough opening. Insert installation places a new window inside the existing frame. Full-frame is preferred in Westboro's older homes because it reveals (and allows repair of) any hidden moisture damage or insulation gaps. Insert installation reduces the glass area and is best reserved for homes with sound existing frames. Expect to pay more for quality in Westboro: The neighbourhood's home values justify premium windows and expert installation. Saving $3,000 on a budget window job in a $900,000 Westboro home is false economy — poor windows or installation are immediately visible and detract from the home's value.
Triple-pane vs double-pane: Triple-pane windows are increasingly standard in Ottawa and are strongly recommended for Westboro homes. The third pane adds approximately $50–$100 per window but provides measurably better insulation (R-5 to R-8 vs R-3 to R-4 for double-pane), reduced condensation, and superior noise reduction. In Ottawa's -30°C winters, triple-pane windows feel noticeably warmer to sit beside. Low-E coatings: Multiple low-E (low-emissivity) coatings on glass surfaces reduce heat transfer. Standard for all quality windows in 2026. Specify coatings on surfaces 2 and 5 (counting from outside) for optimal Ottawa performance. Argon vs krypton gas fill: Argon gas between panes is standard and cost-effective. Krypton is a better insulator but costs more and is typically used only in triple-pane units where the pane spacing is narrow. Canada Greener Homes Grant: Westboro homeowners may qualify for rebates of $125–$250 per window (up to $5,000 total) through the federal Greener Homes program. Requirements include a pre-retrofit EnerGuide home evaluation and purchasing ENERGY STAR certified windows. Enbridge rebates: Additional rebates may be available through Enbridge Gas for energy efficiency upgrades. Check current program availability and requirements. The combination of energy savings ($300–$800 per year on a full-home replacement) and available rebates ($1,500–$5,000) makes 2026 an excellent time for Westboro window upgrades.
For a typical Westboro home with 15–20 windows: vinyl windows cost $10,000–$18,000; fiberglass costs $14,000–$28,000; aluminum-clad wood costs $22,000–$45,000. Custom sizes for character homes add 15–30% to standard pricing.
If your Westboro home is heritage-designated or within a heritage conservation district, yes — you need a heritage permit before replacing windows. This requires maintaining original proportions and using approved materials. Non-heritage homes don't need a heritage permit.
Fiberglass windows offer the best performance-to-value ratio for most Westboro homes. For heritage or high-value homes ($900K+), aluminum-clad wood provides the best combination of interior warmth and exterior durability. Always choose triple-pane for Ottawa's climate.
A full-home window replacement (15–20 windows) typically takes 2–4 days for installation. Lead time for ordering custom or specialty windows is 4–10 weeks. Heritage permit approval, if required, adds 4–8 weeks before ordering.
Replacing all windows at once is more cost-effective (contractors offer volume pricing) and ensures consistent appearance. However, phased replacement (front/street-facing first, then sides and rear) is a viable option if budget is a constraint. Many Westboro homeowners phase over 2 years.
