When patching stops working, a complete replacement fixes the wall system underneath — not just the surface you can see.
A full replacement strips the wall back to sheathing and rebuilds the exterior system in the right order. Any contractor quoting a full job should be able to walk you through these steps without hesitation:
| Situation | Usually right |
|---|---|
| A few cracked panels after a storm | Repair |
| One rotted trim board, walls otherwise sound | Repair |
| Warping or buckling across multiple walls | Replacement |
| Repeated failures at the same seams or corners | Replacement |
| Moisture signs inside at exterior walls | Replacement, with sheathing work |
| Wood siding needing paint every few years | Replacement, if you're done maintaining it |
Connecticut planning ranges run roughly $12,000–$22,000 for vinyl, $20,000–$40,000 for fiber cement, and $18,000–$35,000 for engineered wood on a typical home, with the whole-house range across materials around $16,500–$41,250. The quote that matters is the one measured on your walls, itemized by material, tear-off, sheathing method, wrap, flashing, and trim. See the pricing guide for the cost drivers to check it against.
One red flag: a “full replacement” quote that reuses old flashing or skips house wrap to hit a price. Those are the two items most likely to cause the next wall failure — and the two cheapest to do right while the walls are open.
