Damaged siding does not always mean new siding. Sometimes a section repair is the smart, lower-cost choice. Other times, patching only delays a bigger problem. Here is how to tell the difference.
Repair makes sense when
- Damage is limited to one area or a few boards
- The weather barrier behind it is in good shape
- Your siding is still available or can be matched
- The rest of the house is not showing leaks
Replacement makes sense when
- Several walls show swelling, cracking or rot
- There is no house wrap or flashing behind the siding
- Your siding is discontinued or cannot be matched
- Paint fails on most walls every few years
- You are planning other exterior work anyway
Cost comparison
| Option | Typical scope | Typical range |
|---|---|---|
| Patch repair | A few boards and wrap | $800 – $3,000 |
| One wall | Strip, wrap, flash and re-side | $5,000 – $15,000 |
| Whole house | Full re-side | $30,000 – $65,000+ |
Ranges are typical for Snohomish and King County in 2026; your price depends on size, height, material and what we find behind the siding.
The middle option: replace one elevation
Often one wall, usually the south or west side, takes most of the weather. Replacing that wall with new wrap and flashing fixes the worst exposure without re-siding the whole house.
Why we always check behind the siding
Two walls can look the same from outside while one has sound sheathing and the other is rotting. Opening a small area before quoting tells us which repair you actually need.
Frequently asked questions
Can new siding match my old siding?
Usually. We match profile and reveal and paint to blend. Some older cedar profiles need custom milling.
Does replacing siding add value?
New siding with proper flashing improves curb appeal and protects the structure, which buyers and inspectors notice.
How long does siding replacement take?
A single wall takes a few days; a whole house usually takes one to three weeks.
