Sewer backup insurance is not as expensive as you may think. It normally costs roughly around $40 to $250 every year. It’s an investment that could save you a lot more in case of an emergency. How costly the insurance will depend on the probability of your condo encountering water, sewage defects due to damaged sewer pipelines, and the limits you select. Since the cellar is at an increased risk of suffering water damage, you have to choose your limits based on what you’ve stored in it. Make sure that you file insurance that covers all water damage in case that occurs in your condo. Of course, it’s important to evaluate how much the insurance costs relative to how much you earn. Regardless, it’s worth considering since it could end up saving you money in the long run.
