Siding replacement projects are an excellent opportunity to insulate and air-seal a home's walls. Re-siding projects provide rare access to a home's exterior, making window and insulation renovations a handy and cost-effective option. By performing these upgrades during an already scheduled and budgeted re-siding project, homeowners can save thousands of dollars while only adding a few days to the project and avoiding the homeowner disturbance that separate projects would cause. The result is lower utility bills—about 15% on average—and greater comfort. In the Mixed-Humid climate zone this added investment has a positive Net Present Value (NPV) and can pay for itself in as little as 7 years.
