Window Replacement in Lynnwood
We replace drafty, fogged and rotting windows with new double-pane units, measured to each opening and sealed so rain stays outside. You get a straight answer on insert or full-frame, a written estimate, and a crew that treats your home the way we'd want ours treated.

When new windows are the right call
A window fails in a few predictable ways. The seal around the insulated glass unit breaks and moisture fogs the space between the panes. Aluminum frames conduct cold straight into the room and drip condensation onto the sill. Wood sills soak up water until they go soft. Once the frame or sash is the problem, not just one pane, replacement usually costs less over time than chasing repairs.
Not every tired window needs to go. If the frame is sound and only one glass unit has fogged, our Window Repair service can often swap the glass alone. We tell you which side of that line each window sits on, even when the smaller job is the answer.
Around Lynnwood, months of damp, mild weather mean condensation and slow leaks do more damage than hard freezes. That is why we spend as much attention on flashing and sealant as on the window itself.
What a window replacement includes
- Measuring every opening
- We measure each opening in three places for width and height and check it for square. Windows are ordered to those numbers, not to a standard size that gets shimmed to fit.
- Insert or full-frame, explained
- An insert window fits inside the existing frame and leaves interior trim and exterior finishes alone. A full-frame install removes everything down to the rough opening, which lets us inspect and fix rotted framing. We show you what we found and why we recommend one or the other.
- Frame and glass choices
- Vinyl is the common choice for value and low upkeep. Fiberglass expands and contracts at nearly the same rate as glass, so it holds its seals well and suits darker colors. Most units come with Low-E coated glass and argon fill to cut heat loss and fading.
- Flashing and sealing
- On full-frame installs we lay sill pan flashing and lap the flashing tape in the right order so water drains out, not in. Gaps get low-expansion foam, which insulates without bowing the frame, then exterior sealant.
- Code details handled
- Bedroom windows need to meet egress size, and glass near doors, tubs and floors has to be tempered. If an opening is being enlarged, we pull the permit.
- Cleanup
- Old units, glass and trim scraps leave with us. We vacuum the work areas inside and pick up outside before we go.
Signs your windows are due for replacement
Fog between the panes
Moisture trapped inside the glass means the edge seal has failed and the gas fill is gone. When several windows of the same age show it, more are usually close behind.
Water on the sill every morning
Heavy condensation on the inside glass points to single-pane or aluminum frames that run cold. Over a winter it feeds mildew and stains the drywall below.
Soft or dark wood
Press a screwdriver into the sill or lower sash. If it sinks in, rot has started, and it usually runs deeper than it looks.
Sashes that stick or won't lock
Warped frames and worn balances make windows hard to open and leave gaps at the lock. A window that won't latch tight also won't seal against wind.
Drafts you can feel
A cold stream along the frame on a windy day means air is moving through failed weatherstripping or gaps around the unit itself.
What moves the price
Every quote is built from your own windows, so we won't guess at a number until we've seen them. A few things make most of the difference, and we list each one on the estimate so nothing surprises you later. We also offer flexible payment options.
Number and size of windows
Large picture windows and oversized sliders cost more to build and need more hands to set. Doing several at once is more efficient than one at a time.
Insert versus full-frame
Inserts take less labor. Full-frame work adds removal, new trim and flashing, and is the right choice when the old frame is rotted.
Frame material and glass
Fiberglass costs more than vinyl. Tempered glass, triple panes, grids and specialty shapes each add to the price.
What's behind the old frame
Rotted sills or framing found during removal have to be repaired before a new window goes in. We show you photos and explain the fix before doing that work.
Access and permits
Second-story windows over a slope or deck need ladders or staging. Enlarging an opening adds a header change and a permit.
How the job runs
- 1
Consultation at your home
We look at each window, check frames for rot, and talk through materials and styles. You get a written, line-item estimate, and there is no pressure to decide on the spot.
- 2
Final measure and order
Once you choose, we take exact measurements and order the windows. Custom units take some time to build, and we schedule your install date when they arrive.
- 3
Install day
We lay drop cloths, remove one window at a time so your home is never left wide open, then set, level, flash and seal each new unit. Most installs are finished in a single day.

Walkthrough
Before we leave, we open, close and lock every window with you and point out how the tilt-in sashes clean.

Window replacement questions
Do I have to replace every window at once?
No. Many people start with the windows that are fogged, rotting or facing the weather and do the rest later. We can match styles and colors so the house still looks consistent.
Will you damage my siding or interior walls?
With an insert install, the exterior finish and interior trim stay in place. On full-frame jobs we cut carefully along the frame and replace the trim we remove. We point out ahead of time anything that may need touch-up paint.
Is vinyl or fiberglass better for our wet winters?
Both handle rain well when flashed correctly. Vinyl is the more affordable option and works for most homes. Fiberglass is stiffer and holds up better in large openings and dark colors, which is why some people find it worth the extra cost.
Do I need a permit to replace windows?
Swapping a window into the same opening often doesn't need one, but enlarging an opening or changing framing usually does. We check the rules for your address and pull the permit when it's required.
How long will I be without windows?
We take out and install one opening at a time, so each spot is open for a short stretch. Most installs are finished in a single day, and nothing is left open overnight.
Let's look at your windows together
We'll check every frame, tell you which windows need replacing and which can wait, and leave you a written estimate. Quotes are free and there is no pressure.
