Why homeowners choose this

What actually decides the job

Tear-off is the only point at which the sheathing and the water-resistive barrier can actually be inspected. Anything installed over top hides the condition instead of fixing it.

Pre-1975 walls in this region frequently have board sheathing with gaps, or no sheathing at all behind the original wood cladding.

Sheathing repair gets priced per sheet at tear-off and shown as a separate line, not folded into the base price.

What drives the price

Where the number comes from

What the crew finds once the old cladding comes off — rotted sheathing and failed wrap are the two line items that move a quote.

What we find

Most common failures on London walls

  • Re-cladding over a wall that was already holding moisture, which pushes the problem into the framing.

  • Reusing old trim and capping to save a few hundred dollars on a twenty-year install.

Frequently asked questions

Siding Replacement in London

Should old siding be removed before new siding goes on?

For a replacement, yes. Going over top hides the condition of the sheathing and the water barrier, adds thickness at every window and door, and makes any future warranty claim harder to argue.

How do I know if siding needs replacing or just repair?

Isolated impact damage on an otherwise sound wall is a repair. Chalking across whole elevations, panels that crack when flexed, or moisture showing on interior walls point to replacement.
