  • 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.
