Siding Contractor in Corvallis, OR

Siding does the quiet work of keeping a house dry, insulated, and looking cared for, and most owners barely think about it until it starts to fail. Warped boards, peeling paint, soft spots near the ground, and rising energy bills all trace back to an exterior that has stopped doing its job. Replacing or upgrading siding protects the framing and insulation behind it, sharpens curb appeal, and settles the moisture problems that older cladding lets through. The right material and a clean installation decide whether that protection lasts a few years or a few decades.


Set in the Willamette Valley, Corvallis endures a long, wet season that drives design choices for any exterior. Months of steady rain and damp, shaded conditions feed moss and algae on north-facing walls and push moisture into every seam a siding job leaves open. Cladding that traps water behind it rots sheathing and invites mold, so material selection and careful flashing matter more here than in a dry climate. Houses range from early-1900s bungalows to recent builds, and each vintage brings its own moisture-management demands that a knowledgeable installer plans around.


Founded and run by Ken Basargin, KB Exteriors is a professional siding contractor in Corvallis, OR, and over 20 years of combined experience stands behind every exterior we take on. Our family-owned crew installs and repairs siding, replaces windows, builds and refinishes decks, and handles exterior painting, so one team can restore an entire exterior. We treat moisture control as the core of good siding work, not an afterthought. Careful flashing, proper ventilation, and the right product for each wall are what keep our installations sound long after the job wraps.

Corvallis sits on the Willamette River in Benton County, a mid-valley college town built around Oregon State University. The campus shapes the rhythm of the city, from game days at Reser Stadium to the students and faculty who fill its neighborhoods and keep its older housing stock in constant use. Old and new homes stand side by side, giving the streets a layered, lived-in feel.

Beyond campus, the city keeps a walkable downtown along the riverfront, farmers markets, and quick access to the Coast Range. Marys Peak rises to the west, and trails, parks, and bike routes give the community an outdoor character that residents build their weekends around. Riverfront paths and nearby wineries add to that outdoor draw.


That damp, green setting comes with real weather. Overcast, rainy months run long here, and the moisture that keeps the valley lush is the same force that tests every roof, wall, and deck, which is why exteriors get so much attention from owners who plan to stay.

Selecting the right cladding for a Corvallis home starts with a walk around the property, noting which walls take the brunt of valley rain, which sit shaded and slow to dry, and how much upkeep the owner realistically wants to sign up for. Exposure, wall height, and existing sheathing condition all shape which product performs.


Fiber cement earns its reputation in this climate because it resists rot, swelling, and insects, holds paint through damp winters, and shrugs off persistent moisture. Walls that face driving rain or sit close to grade benefit most from its durability, though its weight calls for careful fastening.


Engineered wood suits owners who want real wood texture with lighter boards and stay current on sealing and paint, while budget-focused projects on sheltered elevations may fit vinyl, provided drainage behind the panels is detailed correctly. A close read of each wall's sun, rain, and ground contact points to the specification that will hold up longest.

Signs Moisture Has Moved Behind Corvallis Siding

 Water intrusion rarely shows itself on the surface first. By the time stains bleed through interior drywall or a musty smell settles into a room, moisture has usually been working behind the cladding for a while, softening sheathing and feeding mold in the wall cavity. The earliest clues almost always sit out of sight, which is why a wall can look fine while trouble spreads.


Outside, the warning signs read plainly to a trained eye. Bubbling or peeling paint, boards that feel spongy underfoot near the foundation, dark streaks below windows, and gaps where trim has pulled away all point to water getting past the exterior and staying there.


Catching these signs early separates a manageable repair from a full tear-off. Left alone, trapped moisture rots framing, ruins insulation, and spreads into structural wood, turning a siding issue into a far larger project. A close look at seams, flashing, and ground contact tells how far the damage has traveled. That inspection also shows whether a repair will hold or a full replacement is the safer route.

Why Corvallis Residents Trust KB Exteriors

 Reputation in this valley travels by word of mouth, and we have built ours as an experienced siding contractor in Corvallis, OR by getting the unseen details right. Over 20 years of combined experience taught us that flashing, wrap, and ventilation decide whether an exterior lasts, so we never cut corners where water can find them.


Ken Basargin runs a family-owned crew that shows up on schedule, protects the landscaping and the interior, and cleans the site before leaving each day. Owners deal with people who answer directly, not a rotating cast of unfamiliar subcontractors. That continuity means the crew that starts your project is the crew that finishes it.


Every project gets the same straight talk about what the walls actually need. We recommend repair when repair will hold and replacement when it will not, and we back our recommendation with what we find behind the siding rather than a sales script. Honesty about scope is what earns the referrals we live on.

Frequently Asked Questions

How do you keep moisture from getting trapped behind new siding?

We install a proper weather-resistive barrier, flash every window, door, and penetration, and leave the drainage plane the wall needs to shed water. That layered approach lets any moisture that gets in drain and dry rather than sit against the sheathing.



Can you match new siding to the look of an older home?

We can. We match profiles, exposures, and trim details so a replacement reads as original, whether the house is a 1920s bungalow or a mid-century build. Keeping the character intact matters as much to us as the weatherproofing underneath.



What preparation happens before you install siding?

We remove the old cladding, inspect and repair the sheathing, and correct any framing or flashing problems we uncover. We also set the weather barrier and trim details first, because clean prep is what makes the finished siding last and sit right.



Can you side our home while we keep living in it?

You can stay put during the work. We tackle the exterior in sections, keep the site secure at the end of each day, and coordinate around your routine so the project moves forward without forcing your family out of the house.



Do you replace rotted sheathing you find during a tear-off?

We do. Once the old siding comes off, we inspect the sheathing and framing, then replace any wood that moisture has softened or rotted before new cladding goes up. Building over damaged sheathing only hides a problem that will resurface.



How do you protect our landscaping during the project?

We cover plants and beds near the walls, set up controlled drop zones for debris, and clean the perimeter as we work. Protecting your yard is part of the job, and we leave the grounds the way we found them.



What finish do you use to help siding hold up in the valley?

We use exterior-grade coatings rated for wet, variable climates and apply them so seams and edges stay sealed. On fiber cement and wood products, the right primer and paint system keeps damp winters from working into the boards.



Will new siding help with drafts and insulation?

It can make a real difference. Correcting gaps, adding a sound weather barrier, and sealing the exterior properly cut the drafts that leak conditioned air, and we can address insulation behind the cladding while the walls are open.
