  • What is home replacement cost?

    Home replacement cost refers to the estimated price of rebuilding a home after a total loss. This entails factors such as local construction costs based on labour, materials, and other pertinent items. The estimate is based on a new construction estimate to restore the structure with a similar level of quality. Replacement costs estimates are not necessarily the same as the market value of a home.

  • How do I calculate the replacement cost of my home?

    It’s important to understand that rebuilding costs and a property’s value are mutually exclusive. To calculate replacement cost, you will need to know the square footage and multiply that times the local cost of new construction. With that base figure, additional costs such as specialty materials, permits, fees, razing, specific home design, number of floors, and many other items must be taken into consideration. Each home has unique aspects that drive costs.

  • How do you measure for total square footage?

    To measure for square footage of your home, always the exterior of the perimeter walls, calculating for angles, possible upper level overhangs which are finished living space, but not below grade level / basement level. 

  • What is the 80% insurance rule?

    Insurance companies may not reimburse the full amount of rebuilding unless a homeowner has taken out a minimum of 80 percent of the structure’s total replacement cost. This remains a significant issue for homeowners who make home improvements without increasing their insurance. In the event of a loss, you may not be fully reimbursed. 

  • Does home insurance impact replacement value?

    Your home insurance policy will outline your home’s replacement value. Each home insurance policy is different, and it is important to check your replacement cost or “blanket” amount. This amount is the insurance provided to rebuild your home if it were destroyed in a fire or other disastrous events.

  • Does replacement cost impact insurance premiums?

    Yes, replacement cost does impact the cost of your insurance premiums. A lower replacement value and lower levels of coverage can reduce your insurance rates.

  • What is the difference between market value and replacement cost?

    Market value is an estimation of the price that your property can sell for on the current market between a buyer and a seller. Replacement cost is the estimated cost to replace a building with equal features and utility to the building being assessed.

  • What is the difference between actual cash value and replacement cost?

    Replacement cost insurance will ensure you receive a payment equal to what would be required to replace the home, whereas Actual Cash Value (ACV) is the estimated depreciated value of your home at the time of the loss.
