In Ottawa, vinyl (PVC) fencing costs more upfront — roughly $40–$80 per linear foot installed — while wood fencing runs about $25–$55 per linear foot, but vinyl is often cheaper over its lifespan because it needs almost no maintenance and lasts longer. A wood fence wins on initial price and looks; a vinyl fence wins on decades of near-zero upkeep. The right choice depends on how long you plan to stay, your appetite for maintenance, and how Ottawa's freeze/thaw cycles will treat each material. This guide compares vinyl and wood fencing on installed cost per foot, lifespan, maintenance, and tota...
Wood is cheaper to install; vinyl is cheaper to keep. Here are typical installed price ranges in the Ottawa market: • Pressure-treated wood fence — $25–$45 per linear foot installed • Cedar wood fence — $35–$55 per linear foot installed • Vinyl/PVC fence — $40–$80 per linear foot installed • Aluminum/ornamental (for comparison) — $45–$90 per linear foot installed For a common 100-foot backyard fence, that means roughly $2,500–$4,500 for pressure-treated wood, $3,500–$5,500 for cedar, and $4,000–$8,000 for vinyl. Prices vary with fence height, style, terrain, post depth for our frost line, and site access. Removal of an old fence and grading add to the total. These figures are for professional installation, which for fencing is usually worth it given the importance of proper post footings in Ottawa's soil.
Beyond material, cost is driven by fence height (a 6-foot privacy fence costs more than a 4-foot fence), post depth (footings must go below the frost line here, which means deeper, more labour-intensive posts than in milder climates), terrain and slope, soil conditions, old-fence removal, and whether a survey or setback check is needed. Corner and gate counts also matter, since gates and end posts cost more than straight runs.
Over 15–20 years, vinyl often costs the same or less than wood once maintenance and replacement are counted. A wood fence's lower purchase price is offset by ongoing upkeep and a shorter lifespan. Consider the total-cost picture. A wood fence typically needs staining or sealing every few years to resist Ottawa's moisture and UV — that's material and either your weekends or a contractor's fee, repeated many times over the fence's life. Boards warp, cup, and rot; posts heave with frost; and a wood fence commonly needs significant repair or replacement in the 15–20 year range, sooner if neglected. Vinyl, by contrast, is essentially maintenance-free: an occasional rinse with a hose is the whole routine. It doesn't rot, won't need staining, and a quality vinyl fence can last decades. When you add up two decades of staining plus a likely wood replacement against a single vinyl installation, the gap narrows sharply or flips in vinyl's favour. If you plan to stay in your home long-term, vinyl's math is compelling. If you'll move within several years, wood's lower upfront cost may make more sense.
For wood fences in Ottawa, the choice is usually cedar versus pressure-treated lumber — cedar looks better and resists rot naturally, while pressure-treated is cheaper and structurally tough. Both are common and both work in our climate with proper care. Cedar has natural oils that resist rot and insects, weathers to an attractive silver-grey if left unfinished, and stays more dimensionally stable. It costs more and is a bit softer. Pressure-treated lumber is chemically treated to resist decay, costs less, and is very strong, but it's more prone to warping and cupping as it dries and generally looks more utilitarian. Many Ottawa homeowners use pressure-treated posts (for ground contact strength) with cedar boards (for appearance) as a middle path. Whichever you choose, sealing or staining extends its life significantly in our freeze/thaw climate.
Ottawa's freeze/thaw cycles are hard on fences, and they affect the cost comparison — proper post footings below the frost line are essential for both materials. When ground moisture freezes and expands, shallow posts heave and lean, and repeated cycles loosen footings over the years. This is why professional installation matters here more than in milder climates: posts set below the frost line in properly compacted or concreted footings resist heaving, while shortcut installations fail within a few winters regardless of the fence material. Wood is additionally vulnerable to the moisture side of the cycle — repeated wetting and freezing accelerates rot and splitting, which is exactly what staining and sealing slow down. Vinyl is unaffected by moisture but can become more brittle in extreme cold; a quality vinyl product rated for cold climates handles Ottawa winters well. In both cases, the footing is the part that determines whether your fence survives a decade of Ottawa winters standing straight.
Each material has clear trade-offs beyond price. Weigh them against how you'll actually use and maintain the fence. Vinyl pros: near-zero maintenance, long lifespan, won't rot or need staining, consistent clean appearance, easy to clean. Vinyl cons: higher upfront cost, fewer style/repair options, can look less natural, damaged panels may need full replacement rather than a board swap, and lower-quality product can crack in extreme cold. Wood pros: lower upfront cost, natural look, easy to repair a single board, customizable and stainable to any colour, widely available. Wood cons: ongoing staining and sealing, susceptible to rot, warping, and insect damage, shorter lifespan, and higher lifetime maintenance cost. There's no universally right answer — there's the right answer for your budget, your timeline in the home, and how much maintenance you're willing to do.
Fence height and placement in Ottawa are governed by the City's fence by-law rather than always requiring a building permit, but there are rules you should confirm before building. Height limits differ between front and rear yards, and pool enclosures have specific safety requirements. Before installing, check the current City of Ottawa fence by-law for height and location rules, confirm your property lines (a survey avoids disputes and encroachment), and talk to neighbours about shared fence lines. If your fence encloses a pool, stricter enclosure requirements apply. Because by-law details and any permit triggers can change, verify current requirements with the City rather than relying on assumptions.
Vinyl (PVC) fencing runs roughly $40–$80 per linear foot installed in Ottawa, or about $4,000–$8,000 for a typical 100-foot backyard fence. Price varies with height, style, post depth for the frost line, terrain, and site access. Vinyl costs more upfront than wood but needs almost no maintenance over its long lifespan.
Pressure-treated wood runs about $25–$45 per linear foot installed and cedar about $35–$55 per foot. For a 100-foot fence that's roughly $2,500–$4,500 for pressure-treated and $3,500–$5,500 for cedar. Wood is cheaper to install but needs periodic staining and has a shorter lifespan than vinyl.
Over 15–20 years, vinyl is often as cheap or cheaper than wood once maintenance and replacement are counted. Wood's lower purchase price is offset by repeated staining and a likely repair or replacement within that window, while a quality vinyl fence lasts decades with only occasional rinsing. If you'll stay long-term, vinyl's math usually wins.
Cedar looks better, resists rot naturally, and stays more stable, but costs more and is softer. Pressure-treated is cheaper and structurally tough but more prone to warping and looks more utilitarian. A common Ottawa compromise is pressure-treated posts with cedar boards. Either way, sealing or staining extends life in our freeze/thaw climate.
Freeze/thaw cycles heave posts set above the frost line and, for wood, accelerate rot and splitting through repeated wetting and freezing. Proper footings below the frost line are essential for both materials. Vinyl resists moisture but can get brittle in extreme cold, so choose a cold-rated product. The footing largely determines whether a fence stays straight for a decade.
Fences are governed mainly by the City of Ottawa's fence by-law, which sets height and placement rules that differ between front and rear yards, rather than always requiring a building permit. Pool enclosures have specific safety requirements. Confirm current by-law rules and your property lines with the City before building.
Usually yes, because proper post footings below the frost line are critical here — shortcut installations heave and lean within a few winters regardless of material. A professional sets posts correctly, handles removal and grading, and ensures the fence follows the property line and by-law, which protects your investment and avoids disputes.
