Portland Exterior Remodeling

Exterior Remodeling in Portland & Vancouver

We've been remodeling exteriors across Portland, Vancouver, and the surrounding SW Washington towns since 2007, on everything from mid-century ranches to century-old foursquares in older neighborhoods. What follows isn't a menu of siding options — it's how the envelope actually keeps a Pacific Northwest home dry, where that system tends to fail, and how we rebuild it so it stops failing.

The envelope, layer by layer

It's tempting to think of siding as the wall, but siding is only the outermost layer of a system that manages water. Rain gets behind cladding on every house — that's expected, not a defect — so the real job is giving that water a fast, uninterrupted path back out before it reaches the wood and insulation underneath.

Behind the siding sits a weather-resistive barrier, the house wrap that sheds bulk water down and away from the sheathing while still letting the wall breathe. At every opening and transition, flashing hands water from one layer to the next: over windows and doors, at the base of walls, where a roof meets a wall, and around every pipe and vent that punches through. Windows and doors are engineered holes in that barrier, so how they're integrated with the wrap and flashing matters more than the units themselves. Trim caps the edges and joints where two materials meet. And above it all, the roofline, gutters, and downspouts are supposed to catch the largest volume of water and carry it clear of the walls and foundation entirely.

When one layer is skipped or lapped the wrong way — house wrap tucked behind flashing instead of over it, a gutter dumping against a wall, trim with an open top edge — water stops draining and starts collecting. That's how a small detail becomes rot inside the wall you can't see. We treat the exterior as the single connected system it is, because that's the only way it holds up here.

Choosing siding for a wet climate

Siding is the decision most homeowners lead with, and in the Northwest the right answer is driven as much by moisture performance as by looks. The four materials below cover the vast majority of what we install. There's no single winner — the best choice depends on your home's style, your appetite for maintenance, and your budget.

Whatever the cladding, its moisture performance is only as good as the barrier and flashing behind it — which is exactly why we spend as much time on what you can't see as on what you can.

Where water actually gets in

Rot almost never starts in the open field of a wall. It starts at the transitions — the handful of spots where the drainage plane is interrupted and one material meets another. These are the details we inspect first and build most carefully, because getting them right is the entire difference between a wall that dries and a wall that stays wet.

Windows & doors

Windows and doors do double duty — they're where the most heat escapes and where water most often sneaks in, so we treat them as an energy upgrade and a waterproofing detail at the same time. In older Portland and Vancouver homes, we frequently open a wall for re-siding and find soft, rotted framing beneath a window that's been quietly leaking for years; catching and repairing that rot is part of doing the job right, not an upsell we hope you won't notice.

New units are only as watertight as their installation. We integrate each window and door with the house wrap and set it on proper pan flashing so any water that reaches the sill drains back to the exterior rather than into the wall. Modern insulated glass cuts drafts and condensation, which matters through a long, damp winter. And because so many homes here have a distinct architectural character, we match the sightlines, grille pattern, and proportions to the house — so a rot repair or an efficiency upgrade reads as original, not like a patch.

Curb appeal that also protects

Once the envelope is sound, the visible choices are where a house finally looks transformed — and the good news is that nearly every one of them is doing protective work, too. Fresh trim isn't only a crisp line around a window; it's the cap that keeps water out of the joint. A quality exterior paint or factory finish isn't just a color; it's the coating that shields the siding from constant moisture and UV. A new front door resets the whole face of the house while sealing one of its largest openings.

Mixing materials — a band of shingle-style siding on a gable, a stone or panel accent at the entry, a contrasting trim color — adds the kind of depth and craftsmanship that make a home stand out on the street, provided it's done with restraint and true to the home's era. That combination of a weather-tight envelope and a considered exterior is also what protects your investment: a home that clearly sheds water and presents well holds its value and its appeal in a way that a fresh coat of paint over hidden problems never will.
