How much does it cost to replace siding?
Replacing siding on an average home runs roughly $6,000 to $16,000 for vinyl and $12,000 to $30,000 for fiber cement. The main drivers are your home's size and number of stories, the material you choose, and whether any sheathing behind the old siding needs repair.
What is the best siding material?
There's no single winner — it depends on your priorities. Vinyl wins on price and low maintenance, fiber cement on durability and fire resistance, and wood on natural looks (with more upkeep). For most homeowners balancing cost and longevity, vinyl or fiber cement are the go-to choices.
How long does siding last?
Vinyl siding lasts about 20 to 40 years, fiber cement 30 to 50 years, and well-maintained wood can go decades but needs regular sealing. Climate matters: intense sun, moisture, and freeze-thaw cycles all shorten a siding's useful life.
How do I know if my siding needs replacing?
Look for cracks, warping, or buckling, sections that are loose or falling off, rot or soft spots, peeling paint that keeps coming back, and rising energy bills. Bubbling or moisture behind the siding is a clear sign to act before water reaches the structure underneath.
Can you put new siding over old siding?
In some cases yes, but it's usually better to remove the old siding first. Taking it off lets the contractor inspect and repair the sheathing, add fresh house wrap, and ensure a flat, sound surface — layering over damage just hides future problems.
Does new siding improve energy efficiency?
It can, especially when insulated siding or added house wrap is part of the job. Siding alone isn't a major insulator, but sealing gaps and adding a proper moisture barrier reduces drafts and helps your heating and cooling system work less.
How long does a siding job take?
Re-siding an average home usually takes one to two weeks, depending on size, material, weather, and any repairs discovered once the old siding is removed. Fiber cement takes longer to install than vinyl because it's heavier and cut differently.
