Bathroom Renovation After Water Damage in Ottawa: Insurance Guide

By Curtis McGrath, Project Coordinator | 18 years renovation experience | Bytown Better Bathtubs and Showers | Updated October 2026

Bathroom water damage is stressful, and the first few hours matter. Ottawa homeowners often call us asking whether insurance will pay, who should come in first, and how long it will take to get a working bathroom back. Our project manager, William Culleton, walked us through how these jobs usually unfold, and the order of calls makes a real difference to both your claim and your timeline.

Who to Call First After Bathroom Water Damage

Will is clear on the sequence. Calling in the right order keeps your claim clean and avoids paying for work twice.

1. Your insurance company

Start with your insurer. They will open a claim, explain what your policy covers, and often send you a list of contractors they work with. Take photos and video of the damage before anything is moved or removed.

2. A restoration company

The restoration company comes next. Their job is to stop further damage: they remove wet and damaged material, dry out the walls and subfloor, and handle water and mould remediation. A bathroom cannot be rebuilt properly until this step is finished.

3. A renovation contractor

Once the room is dry and safe, a renovation contractor such as Bytown assesses what is left and rebuilds the bathroom. Will notes that we seldom work directly with insurance adjusters. In most cases we work through the homeowner, who shares our written quote with the insurer.

Does Home Insurance Cover Bathroom Water Damage?

It depends on your policy and on how the damage happened. Will puts it plainly: coverage varies from one policy to the next and from one type of damage to another.

Usually not covered: slow leaks

A leak from a shower or tub that has been seeping for weeks or months is usually not covered. Insurers often treat gradual seepage and wear as a maintenance issue rather than a sudden event. This is the most common kind of bathroom water damage we see, from failed grout and caulking to a worn shower base.

May be covered: sudden events, flooding and sewer backup

Sudden and accidental water damage, such as a burst supply line, is more likely to be covered under a comprehensive policy. Flooding or a sewer backup that also reaches a basement bathroom may be covered too, but sewer backup and overland flood protection are often separate add-ons to a home policy, so check whether you have them.

How a Bathroom Is Rebuilt After Water Damage

Once the restoration work is done, rebuilding the bathroom follows the same careful process as any renovation, with a few extra checks for bathroom water damage.

Assessment

We look at the subfloor, the wall framing, and the plumbing that was exposed. If the leak came from a shower or tub, we find out why it failed so the new installation does not repeat the problem.

Rebuild and waterproofing

The new shower or tub surround is built as one fully waterproofed system, so water stays where it belongs. This is also a natural time to update the layout, replace an old tub with a walk-in shower, or upgrade the exhaust fan.

Permits

If plumbing or fixtures move during the rebuild, a City of Ottawa building permit may be needed. The fee is usually a few hundred dollars, based on the number of fixtures.

How to Handle Bathroom Water Damage, Step by Step

1. Stop the water and stay safe. Shut off the water supply and avoid any wet area near electrical outlets.
2. Document the damage. Take photos and video before anything is moved or removed.
3. Call your insurer. Open a claim, ask what is covered, and ask for their list of contractors.
4. Call a restoration company. Have damaged material removed and the room dried, with mould remediation if needed.
5. Get a written rebuild quote. Have a renovation contractor assess the room and share the quote with your insurer.

Frequently Asked Questions

Who should I call first after bathroom water damage?

Call your insurance company first, then a restoration company to remove damaged material and dry the room, and then a renovation contractor to rebuild the bathroom.

Does home insurance cover a leaking shower or tub?

Usually not. A slow leak from a shower or tub is often treated as gradual damage or a maintenance issue. Sudden events, flooding, or a sewer backup may be covered, depending on your policy.

Does Bytown work directly with insurance adjusters?

Seldom. In most cases we work through the homeowner, who shares our written quote with the insurance company.

How much does it cost to rebuild a bathroom after water damage?

It depends on the damage, so the rebuild is quoted after an in-home assessment. For reference, a complete bathroom renovation typically runs $20,000 to $25,000 CAD.

Is this insurance advice?

No. This guide is general information only. Your policy wording decides what is covered, so always confirm with your insurance company or broker.
