The Longest Line on the Street
Metal siding is a face made of coil: steel or aluminum, roll formed into a profile, finished at the factory before it ever reaches the site. It does not rot, it does not feed insects, it does not burn, and the finish on a good panel outlasts the paint cycle on anything else we hang. On a modern elevation it is the material that reads sharpest from the street, because a roll formed panel is straighter than any board.
Steel and aluminum are not interchangeable here. Steel is stiffer, which means it holds a long run flat and takes a ladder better. Aluminum cannot rust, which matters on the water, and it weighs a fraction of steel, which matters on a tall gable. We pick between them by elevation and exposure rather than by habit, and we will tell you which one your house actually wants.

Why Metal Siding Is the Sharpest Choice for Modern Homes
The best choice for metal siding installation in greater Seattle
What separates a good metal wall from a bad one is movement. A steel panel on a dark wall grows and shrinks measurably between a February morning and an August afternoon, and if the fasteners pin it, the panel oil cans and the finish works at the fastener. So the panels hang on clips or in slotted holes with room to move, the cavity behind them drains, and dissimilar metals never touch. That is the whole craft of it.
Work With UsThree Ways to Run the Panel
The profile sets how the wall reads and how it fastens. We mock up the one you are leaning toward on your own wall before anything is ordered.
-
Standing seam
Vertical panels with a raised seam at every joint and nothing showing on the face. The crispest wall we build, and the one that suits a modern elevation or a gable with nothing to interrupt it.

Board & batten
Wide flat panels with a narrow batten over every seam, the farmhouse look carried over into steel. It reads tall and clean, and it pairs well with a timber porch or a dark accent wing.

Architectural panel
Large flat metal panels set in a deliberate grid, with a clean reveal at every joint, for a sharp contemporary face. The layout does the design work, so we plan every seam around your windows and doors before a single panel is ordered.

Why Choose Metal Siding?
Metal gives your home a bold, modern look that stands out on any street. It keeps a line straighter than any board can, holds a factory finish far longer than paint, and does not rot or burn, so it stays striking with very little upkeep.

Metal Siding Questions
See All FAQsIt sits at the upper end of what we install. The panels themselves are competitive, but roll formed material has to be ordered to length, trim and flashing are fabricated rather than bought off a shelf, and a concealed fastener system is slower to hang than lap. The online estimator will put a range on your house and the home estimate replaces it with measured pricing.
Yes, and anyone who tells you otherwise is selling. A ladder set against a panel, a thrown ball, or heavy hail will mark it, and aluminum marks more easily than steel. A deeper profile hides a small dent better than a flat one. If your wall takes regular contact, we will point you at a ribbed profile or a different material rather than pretend the problem away.
Not on a wall. The noise people remember comes from metal roofing over an open attic, where the panel is a drum with nothing behind it. Siding sits against sheathing and insulation on the outside of a conditioned wall, and from inside the house you will not pick it out.
Steel is coated on both faces and does not rust from the field, but a raw cut edge or a deep scratch can, and salt air speeds that up. Near the water we usually put aluminum on the exposed elevations, because aluminum cannot rust at all. Either way cut edges get treated rather than left open.
Every exterior finish fades. How fast depends almost entirely on the coating rather than on the metal under it, and the gap between a premium coating and an economy one is large enough that it is worth the conversation at the estimate. Dark colors and south facing walls show it first.
We do not recommend it. Furring over old siding pushes windows and trim out of line, hides whatever condition the sheathing is in, and gives the panels a surface that is rarely flat enough. Metal shows every dip in a wall, so the substrate matters more here than with any other material.
Why Choose Sealed Siding?
The Best Choice for Metal Siding Installation in Seattle
- Panels set with room to move: Clips or slotted fastening at every panel, sized for the run. Metal pinned tight is metal that oil cans and works its finish loose at every fastener.
- Concealed fasteners where we can: A standing seam or flush panel hides its fastening. Exposed fastener systems have their place on outbuildings and budgets, and we will say plainly which one you are buying.
- Dissimilar metals kept apart: Aluminum against steel, copper runoff, treated lumber in contact with a panel. Any of those corrodes a wall from the contact point out, so they get separated or they do not get built.
- A drained cavity behind the face: Metal is the most watertight face we hang, which is exactly why the wall behind it has to be able to dry. Furring, a detailed weather barrier, and flashing at every opening.
