Window Replacement in Sammamish
We fit new windows when repair no longer makes sense: soft frames, rot at the sill, or glass fogging in window after window. Each unit is made to the measured opening, sealed against wet weather and trimmed cleanly inside and out. Most installs are finished in a single day.
New windows, when they are the right answer
Plenty of windows can be saved. A sticking sash, a worn balance or a single fogged glass unit is usually a repair job, and when that is what we find, we say so and point you to our window repair service. Replacement earns its cost when the frame itself is failing, when seals have given out across the house, or when the original units were never very good.
A lot of houses in and around Sammamish were built with aluminum windows or first-generation vinyl. Aluminum carries winter cold straight into the room and beads with condensation from fall through spring, while older vinyl tends to bow or crack with age. Well-made modern units change how a room feels on a January morning, how much road noise reaches you and how easily the sash moves.
We install vinyl, fiberglass and wood-clad frames, usually starting with double-pane low-E glass. As you decide, we explain how each material ages and what upkeep it asks of you, so the choice stays yours.
What the work includes
Measuring and a frame check
We measure every opening ourselves and look over the sill, jambs and surrounding trim for signs of moisture. What we find decides whether an insert or a full-frame install suits the opening.
Frame and glass choices
Frames come in vinyl, fiberglass or wood-clad. Glass options include low-E coatings, argon fill and obscured panes for bathrooms. We bring samples so you can see the finish and weigh the tradeoffs side by side.
Careful removal
Old sashes and frames come out with as little disturbance to drywall and exterior trim as the opening allows. We haul off the old units and all the packaging.
Flashing and sealing
Each new unit is set level and square, insulated with low-expansion foam and flashed so water drains to the outside. Exterior sealant goes on last, tooled neatly to suit the finish of your home.
Interior finish and cleanup
We fit or reinstall interior trim, test that every sash opens, locks and seals, and leave the rooms tidy.
Glass break warranty
The windows we install come with a glass break warranty. We go over what it covers with you before any work starts.
Signs it may be time for new windows
Fogging on several windows
One fogged unit is often a glass repair. When seals have failed across most of the house, new windows usually cost less over time than fixing them one at a time.
Soft or stained wood at the sill
Push a screwdriver tip into the sill. Wood that gives easily means moisture has been working its way behind the frame, and patching the surface tends to hide the damage rather than stop it.
Wet aluminum frames each morning
Condensation collecting on cold metal through the winter feeds mildew and slowly ruins paint, drywall returns and trim.
Bowed or cracked vinyl
Early vinyl can warp as it ages, opening gaps that let drafts through no matter how much weatherstripping goes on.
Sashes that drift or drop
Worn balances are an easy fix. A frame that has twisted out of square is not, and new hardware in it will not hold for long.
How the work goes
- 1
A phone conversation
You tell us which windows bother you and why. We set a time to come and look, with no pressure to buy.
- 2
Inspection and a written estimate
We check each window, photograph anything worth showing you and hand you a line-item estimate. If a repair will do, you hear that from us first.
- 3
Ordering
Your windows are built to the measured openings. We confirm the order with you, then schedule the install once the units arrive.
- 4
Install day
Drop cloths go down and furniture near the openings is moved or covered. We take out one old unit, set and seal its successor, then move on, so no room sits open for long. Most homes are done in a single day.
- 5
Walkthrough
At the end of the day, we open and lock every window with you, explain the care each material needs and answer any remaining questions.
What shapes the price
Every estimate is written out line by line, so you can see where the money goes. The window count matters, but it is rarely the only thing that moves the total. If paying over time suits your budget better, ask us about our flexible payment options.
- Size and style
- Large picture windows, casements and specialty shapes cost more to build than standard sliders or single-hung units.
- Frame material
- Vinyl is usually the most economical. Fiberglass and wood-clad frames cost more for their stiffness and finish.
- Insert or full-frame
- An insert fits inside a sound existing frame. A full-frame install goes back to the studs, which adds labor and trim work.
- Hidden damage
- If the sill or framing has rotted, it needs fixing before the new unit can be set. You get photos and a price for that work first, and nothing goes ahead without your okay.
- Access and permits
- Upper-story windows above slopes or decks take more setup. If an opening changes size, a permit may be needed, and we take care of it.
Questions about new windows

Do I need to replace all my windows in one go?
No. A common plan is to replace the few in the poorest condition now and leave the rest for a later season. We keep a record of the styles and finishes you chose so the later windows match the earlier ones.
Can you just swap the fogged glass instead?
Often, yes, if the frame and sash are sound. In that case we will suggest window repair rather than a whole new unit. If the frame is failing too, fresh glass in an old frame is not a good use of your money.
What is the difference between an insert and a full-frame install?
An insert sits inside your existing frame, so most of the trim inside and out stays put. A full-frame install strips the opening back to the framing, which lets us see and correct hidden water damage. We suggest that route only when the old frame gives us a reason.
How long will my home be open to the weather?
Only briefly at each opening. We work window by window, sealing each new unit before the next old one comes out. Most installs wrap up in a single day.
What happens if you find rot once the old window is out?
Work on that opening pauses while we show you the damage. We explain what the fix involves and what it adds to the cost, and you decide whether we continue.
Find out what your windows actually need
We will look at each window, tell you plainly whether it calls for a repair or a new unit, and put the estimate in writing.
