Secondary suites have become far more common in Calgary in recent years, especially since the City’s 2024 rezoning changes made it easier to add them in many neighbourhoods. More basement suites means more tenants living at the lowest, most flood-prone level of the house. When water hits a suite, landlords and tenants both need to act quickly. General information only. Alberta’s Residential Tenancies Act, your lease and your insurance policies govern specific situations.

Why Suites Are High-Risk

• They’re below grade, where sewer backups, groundwater and overland water arrive first.
• They sit under the main floor’s kitchen, laundry and bathrooms.
• They have their own plumbing: a second kitchen, bathroom and often laundry.
• Communication between two households can slow the response.

Tenants: First Steps

1. Stop the water if you can (fixture valve or main shut-off).
2. Notify the landlord immediately, by phone and then in writing with photos.
3. Move your belongings to a dry area.
4. Call your tenant insurer about damaged belongings or a place to stay.
5. Keep receipts.

Landlords: First Steps

1. Start emergency extraction and drying right away.
2. Document the cause and damage.
3. Notify your insurer. You need a policy that properly covers a rented suite.
4. Follow Alberta’s notice rules for entry for non-emergency work.
5. Agree on a plan with your tenant if the suite isn’t livable.

Who Typically Pays

Item	Usually covered by
Building: drywall, flooring, cabinets, fixtures	Owner’s insurance (if the cause is covered)
Tenant belongings	Tenant’s insurance
Tenant’s temporary housing	Tenant’s insurance
Lost rent	Owner’s policy, if it includes rental income coverage

Tenants should always carry tenant insurance; the landlord’s policy usually won’t cover their things.

Building or Renovating a Suite? Plan for Water

• Backwater valve on the main sanitary line
• Sump pump with battery backup if your home has one
• Moisture-tolerant flooring like luxury vinyl plank or tile
• Moisture-resistant board at the bottom of walls
• Leak sensors under both kitchens, laundry and water heaters
• Accessible shut-off valves that both households know about
• Adequate sewer backup coverage, because suites raise the potential loss

We respond 24/7 to occupied suites, keep tenants informed, document the loss for both the owner’s and tenant’s insurers, and rebuild so the suite can be rented again quickly. Learn more about water damage restoration in Calgary, check typical costs, or read about sewer backups and mould.

Calgary homeowners file a lot of property claims: hail, burst pipes, sewer backups and the occasional river flood. Each type of water damage is treated differently by insurers. This guide explains how Calgary water damage claims typically work and how to avoid the most common mistakes. General information only, not insurance advice. Your policy and broker have the final say.

Which Coverage Applies?

What happened	Typical coverage
Burst pipe, failed hot water tank, appliance hose	Standard policy (sudden and accidental)
Hail damages roof or windows, then water gets in	Standard policy (wind/hail peril), possibly with a hail deductible
Ice dam backs water into ceilings	Often covered; varies by insurer
Sewage comes up the floor drain	Sewer backup add-on only
River or surface water enters the home	Overland flood add-on only
Groundwater seeps through the foundation	Often excluded; some water add-ons include it
Long-term slow leak, wear and tear	Generally excluded

The Calgary Claim Playbook

1. Stop the water and prevent more damage. Start mitigation immediately; you don’t usually need to wait for the adjuster.
2. Document first: photos and video of water levels, the source, damaged contents and, for hail, the roof, siding and windows from the ground.
3. Keep evidence: the failed pipe or hose, hailstones in the freezer for scale (seriously, it helps).
4. Report quickly. After big hail or flood events, call volume is huge; early claims get adjusters sooner.
5. Inventory contents with age and value.
6. Keep receipts for emergency work, tarps, hotels and meals.
7. Compare scopes: the adjuster’s estimate vs your restorer’s estimate, line by line.

Documentation That Gets Claims Approved

• Moisture maps showing the full extent of water (including inside walls)
• Daily drying logs proving drying was done properly
• Photos before, during and after removal
• Cause and water category notes
• Itemized estimates with mitigation and reconstruction separate

A professional water damage restoration company in Calgary provides all of this. You can usually choose your own contractor. See how to choose one.

Hail + Water Claims: A Calgary Special Case

If hail damaged your roof and water is now leaking in, report both the hail damage and the interior water damage together. Waiting months to report interior leaks can lead insurers to argue they’re maintenance-related. See hail damage leaks.

Poly-B and Older Plumbing

Some insurers restrict coverage on homes with Poly-B or aging plumbing. Know what your policy says before a leak happens. See frozen pipes and Poly-B.

Disputes

Ask for the decision and the specific policy wording in writing, use the insurer’s internal complaint process, and if needed contact the General Insurance OmbudService.

From high-rises in the Beltline, East Village, Downtown West End and Mission to townhouse complexes in Royal Oak, McKenzie Towne and Tuscany, Calgary has a huge condo market. In a condo, water doesn’t respect unit boundaries. A leak in one suite can damage several, and the financial fallout can land on the owner where it started. General information only, not legal advice. Your corporation’s bylaws, its insurance and Alberta condominium legislation govern your situation.

Alberta’s Deductible Chargeback Rules

Alberta’s condominium regulations, updated in 2020, allow a condo corporation in many cases to recover its insurance deductible from the owner of the unit where the damage originated, up to $50,000 for a residential unit. With water damage deductibles on many Calgary buildings in the tens of thousands of dollars, one failed washing machine hose can be very expensive.

That’s why your condo owner’s policy should include deductible coverage (sometimes called loss assessment) with a limit that matches your building’s water deductible. Get a copy of the corporation’s insurance certificate and ask your broker.

Owner Checklist: What Your Policy Should Include

• Deductible / loss assessment coverage matched to the building’s water deductible
• Improvements and betterments beyond the standard unit
• Contents
• Additional living expenses if you have to move out
• Personal liability for damage to other units
• Sewer backup if you’re on a lower floor or own a townhouse with a basement

When Water Appears

1. Call building management, security or the after-hours line immediately.
2. Shut your in-suite valve if the leak is in your unit.
3. Warn neighbours below.
4. Document with photos, video, times and names.
5. Notify your insurer and the board/manager in writing.
6. Get drying started fast. Delays make the loss, and the deductible fight, bigger.

Common Calgary Condo Leak Sources

• Washing machine and dishwasher hoses
• Toilet supply lines and overflows
• Shower and tub leaks from failed caulking or grout
• In-suite hot water tanks
• Fan coil and heat pump condensate overflows
• Frozen sprinkler lines or pipes near balcony doors after a Chinook cold snap
• Window and balcony door leaks during hail and wind-driven rain
• Poly-B plumbing in older buildings

Condo Restoration Done Right

We coordinate access with property managers and boards, protect hallways and elevators, follow building rules and document each unit separately, which is critical when the corporation and several owners each have a stake. Concrete buildings dry slowly, so we monitor daily. Learn more about water damage restoration in Calgary.

Prevention Tips

• Replace appliance hoses with braided stainless every 5 years.
• Install leak sensors with auto shut-off.
• Replace hot water tanks before end of life.
• Re-caulk tubs and showers when caulk cracks.
• Shut the in-suite valve when you travel.

Whether it’s a hail-cracked skylight leaking into a Saddle Ridge bedroom, a Chinook-thaw burst pipe in a Varsity bungalow, or a dishwasher flood in a Beltline condo, Calgary homeowners all ask the same question first: how much will water damage restoration cost? Here’s a realistic 2026 breakdown for Calgary, and what drives the price up or down.

Calgary Water Damage Restoration Prices at a Glance

Most residential water damage jobs in Calgary cost between $2,500 and $25,000. A typical developed-basement loss lands around $8,000 to $18,000. River or overland flooding and sewer backups with full rebuilds can go far higher.

Scenario	Typical range (CAD)
Small supply-line or toilet leak, caught early	$1,200 – $3,000
Hot water tank failure in the basement	$2,000 – $6,000
Hail or roof leak into ceilings and walls	$3,000 – $12,000
Burst pipe, one level	$4,000 – $9,000
Developed basement or suite flood	$8,000 – $20,000
Sewer backup (Category 3)	$12,000 – $35,000+
Overland or river flood, full basement rebuild	$30,000 – $100,000+

Rule of thumb: $4–$7 per sq. ft. for mitigation (extraction, drying, antimicrobial) and $8–$15 per sq. ft. with reconstruction. These are planning ranges, not quotes; your price comes from an on-site assessment.

What Pushes Calgary Restoration Costs Up

Speed of response

Every hour, water climbs higher into drywall and deeper into subfloors. Calgary’s dry air helps a little, but wet materials in a closed basement still need professional drying, and mould can start within 24–48 hours.

Storm-driven demand

After a big hailstorm or a Chinook-to-deep-freeze swing, thousands of Calgary homes are hit at once. Booking quickly gets you in the queue sooner.

Water category

Clean water is cheapest; sewage and river water are Category 3, requiring removal of porous materials and disinfection. See sewer backup cleanup and river flooding.

Developed basements and suites

With secondary suites becoming more common across Calgary, more basements have full kitchens, bathrooms and finishes, which means more to remove and rebuild. See basement suite water damage.

Ceiling and roof damage

Hail and ice dam leaks travel through attic insulation, ceilings and walls, affecting more area than you see. See hail damage leaks and Chinook ice dams.

Mould

Water left too long often adds remediation costs. See mould after water damage.

Will Insurance Cover It?

Sudden, accidental water damage like a burst pipe or failed tank is typically covered in Alberta. Hail damage to the roof is usually covered too. Sewer backup and overland flood generally require add-on coverage. See our Calgary insurance guide.

Six Ways to Spend Less

1. Shut off the main water valve immediately.
2. Call for extraction right away, day or night.
3. Photograph everything before cleanup.
4. Ask for mitigation and reconstruction estimates separately.
5. Rebuild smarter: moisture-resistant materials low on basement walls.
6. Prevent the next one: backwater valve, roof inspection after hail, pipe insulation.
