A windstorm or heavy snow can tear your home’s electrical mast loose in Calgary. Here’s who’s responsible — the utility or you — and what to do first.
In Calgary, the utility (ENMAX in the city, FortisAlberta in most surrounding communities) owns the overhead wire reaching your home and the meter itself. You own the mast, the meter base and the wiring from there into your panel — so storm damage to the mast is your repair, usually covered by home insurance. If a wire is down, sparking or touching anything, treat it as live, stay back and call 911.
When a windstorm, a hailstorm or a heavy snow load tears your home’s electrical mast loose in Calgary, the first question isn’t the permit — it’s whether that wire is still live. Here’s the short version: inside the city, ENMAX owns and maintains the overhead line running to your house and the meter itself; you, the homeowner, own the mast, the meter base, and everything from there into your panel. That makes electrical mast repair in Calgary a homeowner job, not a utility one, even though the storm hit a piece of infrastructure that looks like it should belong to the utility. Knowing which side of that line you’re looking at decides what you do in the next five minutes.
“Inside Calgary, ENMAX owns the wire that reaches your house and the meter; you own the mast, the meter base and the conductors running into your panel — so mast damage is a homeowner repair, even when the storm that caused it was entirely out of your control.”
Who owns what: the line that splits responsibility
Every overhead electrical service has a dividing line, usually called the point of attachment or weatherhead, and it decides who pays for what. On one side sits the utility’s equipment; on the other sits yours. Both ENMAX and FortisAlberta publish this same split for their Calgary-area customers, so a homeowner who understands it stops wasting time arguing with the wrong office after a storm.
- Utility side (ENMAX inside Calgary; FortisAlberta in most surrounding communities): the overhead service drop running from the pole or transformer to the point of attachment on your mast, plus the meter itself.
- Your side: the mast, the weatherhead, the meter base the meter plugs into, and the service entrance conductors running down the mast and into your panel.
- Underground-fed homes skip the overhead mast, but the buried conductors from the transformer to your meter base still cross a similar ownership line — worth confirming with the utility if a dig-in or ground movement is the cause of the damage rather than wind.
A downed or leaning mast is a 911 call, not a repair call
If a mast or wire is down, sparking, smoking, or touching the ground, a fence, a vehicle or standing water, stay back, keep children and pets well clear, and call 911. Then report it to the utility so the line can be confirmed de-energized at the pole or transformer before anyone — including an electrician — goes near it: ENMAX inside Calgary, or FortisAlberta at 310-WIRE (310-9473) in most surrounding communities. A mast that’s simply pulled away from the wall but still has slack wire attached deserves the same caution: it doesn’t have to be arcing to be carrying full voltage, and an electrician won’t touch it until the utility confirms it’s safe.
What happens next: de-energize, assess, repair, re-energize
Once you’ve reported the damage, the repair follows a predictable sequence, and knowing the order helps you plan around the outage instead of being surprised by it.
- Report & de-energize — the utility sends a crew to disconnect power at the pole or transformer, at no cost to you, before any work on the mast can safely start.
- Assess & quote — a licensed electrician inspects the mast, weatherhead, meter base and service conductors to see whether this is a strap-and-bracket fix or a full mast and meter base replacement.
- Permit & repair — for anything beyond a like-for-like fix, the electrician pulls the City of Calgary electrical permit (or the matching process for your municipality or county) and completes the repair.
- Inspect — the permit authority inspects the finished work before the utility will reconnect.
- Re-energize & reseal — the utility restores the connection and reseals the meter once the inspection has passed.
What a mast repair costs in Calgary
Re-securing a mast that has only pulled loose from its strap or bracket, with the meter base and conductors undamaged, typically runs about $300 to $700. Replacing a cracked meter base or damaged service entrance conductors along with the mast is more often $800 to $2,000 or more, depending on access and roof height. If the storm also twisted or damaged the panel itself — common when a falling tree limb or heavy ice loads the whole service entrance at once — the job folds into a larger repair or upgrade, and our guide to what a panel upgrade costs in Calgary covers what drives that bigger number.
Will home insurance cover it?
Most homeowner policies cover wind, hail and snow-load damage to equipment you own, including the mast and meter base, subject to your deductible — the utility’s own wire and meter aren’t yours to insure in the first place. Keep the electrician’s written assessment and repair invoice; insurers generally want documentation that ties the damage to the storm date before they’ll pay a claim.
Rural and acreage services see more of this
Acreages in Rocky View County and Foothills County, where FortisAlberta is the utility, often run longer overhead spans from the pole to the mast than a city lot does, and more exposed wire means more wind and ice loading over the life of the service. If your property’s overhead run is long, aging, or has a history of sagging in heavy snow, it’s worth having an electrician look at the whole service — not just the mast — as part of our acreage and rural electrical work.
From a wind-snapped mast in Bowness to a service pole knocked sideways on an acreage near Cochrane or Airdrie, Shock Stop treats storm damage like the emergency it is: make the site safe first, then handle the mast, meter base or panel repair with the permit and inspection taken care of. If a wire is down or sparking, call 911 and the utility first — see our emergency electrician page for what an after-hours call covers. For everything else, including a next-morning assessment, reach out for a quote across Calgary, Airdrie, Cochrane and the surrounding communities.
Questions about this
Who owns the electrical mast on my house — me or the utility?
You do. Inside Calgary, ENMAX owns and maintains the overhead service drop running to your property and the meter itself. Everything from the point of attachment down — the mast, the weatherhead, the meter base and the conductors running into your panel — belongs to the homeowner. The same split applies outside the city with FortisAlberta as the utility.
Is it safe to touch a mast that’s pulled away from the house but the wire still looks intact?
No. Treat any mast or wire that has shifted, fallen or is leaning as live until the utility confirms it has been de-energized. A wire doesn’t have to be sparking to be dangerous — slack in the line, contact with a fence or a wet surface, or a mast simply pulled off its bracket can all still be carrying full voltage.
Do I need a permit to repair a storm-damaged mast in Calgary?
Usually yes. Re-securing a mast to its existing bracket with no other damage is sometimes minor enough to skip a permit, but a cracked meter base, damaged service conductors or any work beyond a like-for-like fix needs a City of Calgary electrical permit (or the matching process in your municipality) and an inspection before the utility will reconnect.
How long until my power is back on after mast damage?
It depends far more on how quickly a licensed electrician and the inspector can get to the repair than on the utility’s side. Once the fix passes inspection, ENMAX or FortisAlberta typically reconnects and reseals the meter within the same day or the next business day.
Does home insurance cover mast or meter base storm damage?
Usually, yes, subject to your deductible, because the mast and meter base are equipment you own. Keep the electrician’s assessment and repair invoice — most insurers want documentation of the storm damage and the fix before paying a claim.
What’s the difference between a downed-line emergency and a mast repair?
A line or mast that is sparking, smoking, touching the ground, or has brought anything else down with it is a life-safety emergency — call 911 and the utility immediately and keep everyone back. A mast that’s simply bent or pulled loose, with the utility confirming it’s de-energized, is a scheduled repair job for a licensed electrician.
