Siding & Exterior Walls

Siding, Exterior Walls & Wood Repair Across Western Washington.

Chimneyz builds and repairs the skin of your home and the wall behind it. Cladding, the weather barrier, the flashing at every junction and the framing underneath, handled by one licensed Washington team.

Why It Matters

Siding Is a Drainage System, Not a Finish.

Almost every siding failure we open up in Greater Seattle began at a junction: a missing head flashing, no kick-out where a roof meets a wall, cladding running into the grade. Water gets behind the boards, finds nowhere to leave, and goes to work on the sheathing and framing where nobody can see it. By the time it reaches you as a soft wall or a window that will not close, you are no longer repairing siding. We treat the cladding, the barrier, the flashing and the structure as one assembly, because that is what it is.

Siding Installation.

New siding is a weather barrier before it is a finish. We install the drainage plane, the flashings and the clearances first, then hang the cladding over them.

Siding Repair.

Confined damage does not need a whole new envelope. We cut out the failed section, fix the wall behind it, correct what let the water in, and blend the repair back.

Siding Replacement.

When the envelope has reached the end, a full replacement is the cheaper decision. Every square foot of wall is visible once, and we use it.

Fiber Cement Siding.

The Pacific Northwest default. It does not rot, does not feed anything and holds paint through wet winters, provided the clearances and flashing are right.

Wood Siding.

Nothing else looks like real cedar and nothing else asks as much. We install, restore and maintain wood siding, and we are straight about the commitment.

Vinyl Siding.

The lowest-cost, lowest-maintenance option, and the one most often hung as a cover over a wall that cannot drain. We install it properly or tell you it is the wrong call.

Exterior Wall Repair.

When the damage is in the sheathing, studs or rim joist rather than the cladding, you are repairing structure. We cut back to sound material and rebuild it.

Wood Rot Repair.

Soft trim, crumbling fascia, a sill you can push a screwdriver into. We replace the rotted wood and stop the water that is feeding it.

Exterior Water Damage Repair.

Water is getting in and nobody can tell you from where. We trace it to the actual entry point and repair the cause, not the stain.
