Can I put new siding over old?

Vinyl over wood lap siding is technically allowed in some codes but rarely a good idea — moisture gets trapped, and you can't inspect the sheathing.

Siding installation cost in the U.S.

Full siding replacements cluster in the range below. Material is the dominant variable; tear-off and sheathing repair shift the number.

Industry estimate from public-source pricing data. Local prices vary widely — see your metro area below.

Factors that move the price

Material
Vinyl: cheapest, lowest maintenance. Engineered wood + Hardie/fiber-cement: mid, much higher curb appeal and durability. Cedar: high. Stucco + brick: highest install, lowest maintenance long-term.
Wrap + insulation
Behind the siding: housewrap is non-negotiable; rigid foam underlayment is a quality upgrade with real energy benefits.
Sheathing repair
Old siding that's been leaking will have rotted sheathing in spots. Every quality contractor itemizes this as a per-sheet repair.
Trim + corners
Corner posts, J-channel, soffit, and fascia replacement adds line items. A 'siding only' quote that leaves these is usually short the trim that holds it all together.
