When we renovated our own home, we changed the windows because the original windows were not soundproof. Should I pay for the house on the roadside now?

First of all, the problem of leaking windows does not belong to the basic service scope of the property itself. If you buy a new house, you can contact the property for after-sales maintenance during the warranty period. If losses are caused, the property should also be responsible for compensation after sale. You changed this window yourself, and it is no longer within the scope of real estate maintenance. If it is replaced soon, you can contact the manufacturer who replaced the window for maintenance and compensation. Or see if the property management company has this maintenance service and can repair it (usually paid service). Please ask the property to carry out paid maintenance, but the property that leaked before is not responsible.
