Cedar & Stone replaced the siding on our Portland home and coordinated the trim and flashing at the same time. The exterior finally looks designed instead of patched, and it has held up through a full season of Oregon rain.
New windows change how a home feels inside and how it reads from the street. They also change the wall around every opening. Cedar & Stone treats window replacement in Portland as exterior work. We check the trim, flashing, sill, and siding at each opening, then plan the new window so it keeps Portland rain out and looks like it belongs on the house.
Some homes need a few windows. Others need every opening replaced along with new siding and trim. Either way, you see a written scope before any window is ordered; one licensed Oregon contractor, CCB #248200, stands behind the finished opening.
Or call (971) 459-4168 to discuss window replacement.
Most window replacement in Portland is sold as a product. A dealer measures the opening, orders the unit, and installs it into whatever trim and flashing are already there. That works when the opening is sound. It fails quietly when the old window has been leaking into the sill or sheathing for years, because the new unit goes back into the same wet framing.
Cedar & Stone starts with the opening instead of the catalog. Before we recommend a product, we look at the condition of the trim, the sill, the flashing above the head, and the siding that meets the window. On many Portland homes, those details are the reason the old window failed. Replacing the glass without correcting them leaves the real problem in the wall.
When windows are planned together with siding replacement, the whole wall is open. Flashing can be lapped correctly from the start, trim can be resized to suit the new windows, and the finished elevation looks designed rather than patched. When a full re-side isn’t part of the plan, we can still handle targeted siding repair around the openings that need it.
Windows also meet stone accents, entry details, and deck or patio door transitions. We plan those intersections as part of the same scope, so the trades don’t leave gaps for each other to fix.
The right window for a Portland home balances how it looks from the street, how it handles eight months of wet weather, and what it costs over its life. We’ll help you weigh each option against the architecture of the house.
Style follows the house and the room. Double-hung windows fit most traditional Portland homes. Casements seal tightly and catch the breeze. Picture windows frame a view, and sliders suit wide, short openings. We’ll walk through each opening with you and recommend a style that matches the home’s architecture and how you use the room.
Every replacement window in Portland must also meet the energy code requirement described below.
Windows rarely fail all at once. Most Portland homeowners notice a slow pattern: a room that never warms up, fog that won’t clear between the panes, or paint that keeps peeling below the same sill. Any one of these signs is worth a closer look, and several together usually mean replacement is the better investment than repair.
Fogging between the panes. Moisture trapped inside a double-pane unit usually indicates a failed seal and reduced insulating performance. The glass can’t be cleaned from either side, so have the unit assessed for repair or replacement.
Drafts and cold spots. Air moving near a closed window means the frame or the seal around it is leaking.
Soft or stained trim and sills. Dark staining, peeling paint, or wood that gives under a screwdriver usually means water is getting behind the trim. This is the sign that matters most, because it points to damage in the wall, not just the window.
Windows that stick, won’t lock, or won’t stay open. Warped sashes and failed balances are common in older wood and early vinyl windows. They’re also a safety problem in bedrooms, where a window might need to serve as an emergency exit.
Single-pane or aluminum-frame windows. Many Portland homes built before the 1990s still have them. They lose heat quickly and collect condensation on the frame through the wet season.
If you see staining or soft wood around an opening, have it reviewed before ordering new windows. The opening matters as much as the glass.
There are two ways to replace a window, and the right one depends on what we find at the opening.
On many older Portland homes, the answer is a mix. Sound openings on the protected side of the house can take inserts, while weather-exposed openings with staining or rot get full-frame work. We make that call opening by opening during the site review, and the proposal shows which method applies to each window and why.
When you need a permit. Under Portland’s residential window guide, replacing a window in the same opening, with no change to the header and no reduction in the clear opening, doesn’t require a building permit. Adding a new window or widening an opening does. Homes in a design zone or historic district might also need a land use review before the exterior changes. We confirm which rules apply to your address during the consultation.
Energy code. Portland requires replacement windows in existing homes to have a U-factor of 0.30 or lower. U-factor measures how fast heat escapes through the whole window, so a lower number means a better-insulated window. Every window we recommend meets this requirement, and the rating is listed on the label of each unit.
Safety and egress. Some locations near doors, stairs, and bathtubs require safety glazing. Sleeping rooms also need a compliant emergency escape and rescue opening. When we replace a window serving that purpose, we size and specify it to preserve the required clear opening.
Rebates and incentives. Window incentives change often. As of September 2026, Energy Trust of Oregon’s window incentive applies only to certain homes in Southwest Washington, not to Oregon homes. We’ll tell you about any incentive that applies to your project at the time of your quote, and we won’t build a proposal around a rebate you can’t claim.
Every window replacement quote in Portland comes down to a few variables. Knowing them up front makes it easier to compare proposals fairly.
When you compare quotes, check that each one lists the installation method for every opening and states how damaged sills or trim will be handled. A low number that leaves those out can cost more later.

We start with your goals: comfort, noise, appearance, budget, and any other exterior work you’re planning.
This is where we decide whether windows should stand alone or be paired with siding or trim.
We inspect each window, the trim, the sill, and the siding around it, and probe any areas that show staining or soft wood.
This tells us which openings can take an insert and which need full-frame work.
We help you choose frame materials and styles for each opening, confirm energy code and any permit needs, and give you a written proposal.
It lists every window, the installation method, and any related trim or flashing repair.
Our crew removes the old windows, repairs and flashes each opening, installs and seals the new units, and finishes the trim inside and out.
We clean up daily and finish with a walkthrough of every window with you.
Cedar & Stone replaces windows throughout Portland and the surrounding communities. Much of the area’s housing was built between the 1910s and 1970s, which means original single-pane wood windows, early aluminum sliders, and first-generation vinyl that’s reaching the end of its life. Each era has its own trim details and moisture patterns, and we plan around them.
We serve homeowners in Portland, Beaverton, Lake Oswego, Tigard, Milwaukie, Oregon City, Gresham, and nearby communities. If you’re not sure whether your home is in our service area, see all service areas or call us.
Cedar & Stone replaced the siding on our Portland home and coordinated the trim and flashing at the same time. The exterior finally looks designed instead of patched, and it has held up through a full season of Oregon rain.
We had replacement windows installed along with new siding and trim, and they planned every detail together. The whole front of the house looks cohesive now and the home is far more comfortable in Portland winters.
From the new deck to the exterior stone on our entry, Cedar & Stone handled the whole design-build from start to finish. Everything connects cleanly and was clearly built for the Pacific Northwest.
One failing window or a full exterior update: either way, Cedar & Stone reviews every opening and gives you a written plan for each one. Request a consultation or call (971) 459-4168.
