What Is the Average Cost to Fix Water Damage — and Can It Really Be Repaired?

According to Forbes, the cost of water damage repairs starts at $1 (CAD 1.36) per square foot but can easily be much more, depending on the extent of the damage. For complex jobs, damage restoration costs in some locations can reach nearly $15 (CAD 20) per square foot.

Repairs can range from simple DIY cleanup to a tough job best left for professionals, depending on the type of damage and water source. Cleaning up after a small pipe leak may only require removing the water and replacing a small amount of carpet or drywall. On the other hand, the total cost to repair extensive water damage can be extreme.

Based on data from Forbes, the average homeowner pays around $3,300 (CAD 4,485) to restore property after water damage. You could pay as little as $150 (CAD 204) to fix minor flood damage caused by an overflowing toilet. Meanwhile, remediating a flooded basement caused by a hurricane or other natural disaster could cost up to $100,000 (CAD 135,905).

What Are the Different Categories of Water Damage?

Every home is at risk of flood damage, whether it's from a burst pipe, damaged roof or swollen river. Most insurers use guidelines published by the Institute of Inspection, Cleaning and Restoration Certification (IICRC) to determine the type of water damage and whether it's covered by their policies.

Category 1: Clean Water

Water damage caused by clean water sources such as potable water, toilet tanks and melting ice. Clean water poses no health risks, provided you get the damage repaired quickly, usually within 48 hours.

Category 2: Gray Water

Gray water contains contaminants that may pose a mild health risk. It includes water discharged from dishwashers, washing machines and water spilled from the toilet bowl.

Category 3: Black Water

Water that's contaminated by sewage and organic waste. This includes sewage backups, groundwater intrusion from a storm, and generalized flooding of rivers, ponds and the sea. You must remove anything that comes in contact with black water.

Classes of Water Damage

The IICRC standards also define the class of water damage. This is a rating that specifies the amount of moisture absorption, as follows:

Class 1: Minimal Water Absorption

Relatively minor leaks that cause limited damage, which a homeowner can easily clean. According to HomeGuide, the average repair cost for Class 1 water damage is from $150 to $500 (CAD 207 to CAD 691).

Class 2: Significant Water Absorption

Standing water that has saturated carpets, flooring and walls, but not reached the ceiling, insulation and subflooring. Drying Class 2 damage with dehumidifiers and air movers can cost from $1,500 to $5,000 (CAD 2,072 to CAD 6,905).

Class 3: Saturation

Extensive saturation where the water has permeated into the structure of the room or home. Class 3 saturation needs specialized drying equipment and costs between $5,000 and $15,000 (CAD 6,905 to CAD 20,715).

Class 4: Deep and Bound Moisture

Extremely severe water damage caused by prolonged high-level flooding. Prolonged submersion saturates everything, including low-permeability materials, such as bricks, hardwoods, plaster and stone. Expect extended drying times for class 4 water damage. Drying methods include targeted heat drying and the use of desiccants. Costs vary from $15,000 to $100,000 (CAD 20,715 to CAD 138,100).

How Much Does It Cost to Repair Water Damage?

Water damage remediation involves water extraction, drying, mold removal and reconstruction. The approximate costs to fix water damage are as follows:

Emergency Water Removal

A cleaning contractor will remove all freestanding water using pumps and wet and dry vacuums. Costs typically vary between $500 and $6,000 (CAD 691 to CAD 8,286), depending on the affected area and the equipment used.

Cleanup

During cleanup, the contractor removes all flood debris as well as damaged flooring, carpets, furniture and personal possessions. You can expect to pay between $1,500 and $15,000 (CAD 2,072 to CAD 20,715) for demolition, debris removal and basement flood cleanup.

Drying and Dehumidification

Once the home is clean, the contractor can start drying the remaining structure and dehumidifying the home. The cost of this work varies from $1,000 to $12,000 (CAD 1,381 to CAD 16,572), depending on the moisture levels present in the home.

Mold Remediation

Before reconstruction can start, the contractor must remove all traces of mold, particularly in the more humid regions of the country. Mold remediation costs vary between $500 and $12,000 (CAD 691 to CAD 16,572).

Structural Reconstruction

If the floods have damaged the structure of the home, the contractor will need to rebuild affected areas using new materials. The cost for water damage restoration varies significantly, contingent on the extent of the damage, and is between $5,000 and $100,000 (CAD 6,905 to CAD 138,100).

Basement and Foundation Repairs

The approximate cost for cracked and damaged foundations varies between $1,000 and $20,000 (CAD 1,381 to CAD 27,620), depending on the severity of the damage.

Detailed Breakdown of Repair and Replacement Costs

The following list provides a more detailed guide to the cost of specific flood repairs:

Carpet repairs: Following Class 1 flooding, it may be possible to clean, rather than replace, carpets at an approximate cost of $300 to $2,000 (CAD 414 to CAD 2,762). Carpet replacement costs range from $2 to $8 (CAD 2.76 to CAD 11) per square foot.
Hardwood flooring: The installation of replacement hardwood flooring costs between $9 and $25 (CAD 12 to CAD 35) per square foot.
Ceiling repairs: The cost to replace damaged ceilings varies from $50 to $100 (CAD 69 to CAD 138) per square foot.
Drywall repair: The repair or replacement of water-damaged drywall typically costs between $2 and $6 (CAD 2.76 to CAD 8.29) per square foot.
Electrical repairs: Following major flood damage, you're almost certain to need electrical repairs; costs can vary from $50 to $130 (CAD 69 to CAD 180) per hour.
Plumbing repairs: Plumbers charge between $45 and $200 (CAD 62 to CAD 276) per hour to repair or replace damaged pipes and general plumbing.
Appliance repairs: Appliance repairs will cost between $100 and $400 (CAD 138 to CAD 552) each.

What Factors Influence Water Damage Restoration Costs?

Several factors have a bearing on flood restoration costs. These include your location, the extent of the damage, local labor costs, replacement of personal property and whether you have flood insurance.

Climate and Location

If you live in an area that often experiences water-related damage, you'll likely pay more for restoration. Strict local building codes tend to make approvals longer and repairs more expensive.

Degree of Damage

Repair costs following minor flooding are lower than the damages sustained during prolonged and severe flooding. Category 3 water intrusion is most severe because you'll need to rip out and replace anything that's been damaged by black water.

Local Labor Costs

The local cost of labor significantly influences restoration costs. Professional water damage restoration companies charge more for their services, but their expertise and professionalism mean you'll get a better result. Flooding doesn't follow any specific pattern and the odds are you'll need emergency help after hours, which is more expensive.

Personal Property Replacement

You can salvage furnishings and clothing damaged in Category 1 and 2 events. In many instances, though, the extent of the water damage may mean you'll need to buy new possessions. However, you must replace everything that's damaged following category 3 flooding.

Do Insurance Companies Pay for Water Damage?

Water damage restoration costs are high, and without insurance, you may find it difficult to cover the cost of repairs. According to State Farm, floods are the most common natural disaster facing homeowners in the country. You don't have to live near a river to experience catastrophic flooding. Heavy rainfall and snowmelt can overwhelm drainage systems, resulting in localized flooding.

Home Insurance

Standard home insurance generally covers accidental water damage caused by a water leak, provided there's been no negligence. Usually, this cover only extends to Category 1 and Category 2 events, and does not cover flood damage restoration caused by sewage and black water.

Flood Insurance

If you believe there's any risk, however small, of flood damage, then it's best to take out flood insurance. Insurers offer flood insurance under the Federal Emergency Management Agency's (FEMA) National Flood Insurance Program (NFIP). When buying flood insurance, check what the policy covers; many flood policies exclude certain personal property, carpets, wall coverings or temporary housing costs.
