Grasshopper,
You are looking for a
Performance Bond that is actually used to secure the Permit you need to do the sewer work. The bond is a requirement of the property owner, not the
contractor, because it is actually being used to guarantee the property owner will do the work and finish it according the engineers estimates. The property owner is also responsible for the cost of the bonds. It is also important to remember to get the City or County agency handling your project to sign a notice of completion when the work is done and send it to the
bonding company.
