What does a siding scope of work include?

It covers old siding removal, house wrap, new siding installation, trim, caulking, and cleanup. It defines the siding type, color, and payment terms.

Vinyl or fiber cement — which is better?

Vinyl is more affordable and requires less maintenance. Fiber cement (like HardiePlank) is more durable, fire-resistant, and looks more like real wood. Both are good choices — it depends on budget and preference.

Do I need new house wrap?

If the existing house wrap is damaged or wasn't installed, yes. New siding over old, compromised house wrap defeats the purpose. New wrap is cheap insurance.

What about insulation behind siding?

Adding foam insulation behind siding improves energy efficiency. Insulated vinyl siding has foam built in. Rigid foam board can go under any siding type. It adds cost but pays for itself.

Can I modify this template?

Yes. Adjust for your siding type — vinyl, fiber cement, wood, engineered wood, or metal siding.
