Hedges define the character of residential streets across Pointe-Claire and Dorval. A well-maintained cedar hedge offers privacy, wind protection, and year-round greenery. But letting hedges grow unchecked can lead to bylaw complaints, neighbour disputes, and plants that become impossible to restore. Understanding the rules and timing is essential for every West Island homeowner who wants to keep their property looking sharp without running into trouble.
Municipal Height Rules You Need to Know
Both Pointe-Claire and Dorval enforce hedge height limits that many homeowners are unaware of. In most residential zones, front-yard hedges must stay between 1.5 and 2 metres, while side-yard hedges can reach up to 2.5 metres. Corner lots face stricter rules near intersections to maintain driver visibility. Exceeding these limits can result in a notice from the municipality and a deadline to trim. If you are unsure about your specific zone, check your city website or call Service d'Arbres Brandse at (438) 365-5410 and we will look it up for you.
Best Timing for Hedge Trimming
The ideal window for trimming most hedges in the West Island falls between late June and mid-August. By this time, the spring growth flush has finished and the plant has enough warm weather left to heal before winter. For cedar hedges specifically, timing matters even more because cutting into old brown wood will leave permanent bare patches. A second light trim in early September keeps things tidy heading into fall. Two trims per season is the standard recommendation for hedges that stay dense and healthy year after year.
Cedar Hedge Care — The Golden Rule
Cedar hedges are the most common choice in Pointe-Claire and Dorval, and they are also the most commonly butchered. The golden rule is simple: never cut beyond the green growth into the brown, woody interior. Unlike many deciduous shrubs, cedar will not regenerate from old wood. Once you cut too deep, that section stays bare permanently. This is why regular trimming is so important — it keeps the green layer thick enough that you always have room to shape without exposing dead wood.
DIY vs. Professional Trimming
Small hedges under two metres can be maintained with hand shears or an electric trimmer by most homeowners. However, tall hedges, long property lines, and hedges near fences or utilities are a different story. Reaching above shoulder height with a powered trimmer is tiring and dangerous. Professional crews use commercial-grade equipment and can trim a hundred-foot hedge in a fraction of the time it would take a homeowner. The result is a cleaner, more uniform finish that actually promotes healthier growth.
Keep Your Hedges Legal and Looking Great
Whether you trim your hedges yourself or hire a professional, the key is consistency. Two trims per season, staying within municipal height limits, and never cutting into old wood on cedars will keep your property compliant and attractive.
