When you plan new siding, you may have one window that sticks, another with a stain below it, and several that work well. List those openings separately. The scope can include a new unit at one opening, closer evaluation at another, and exterior trim and flashing work around windows you plan to keep.
Use this guide to organize those decisions before requesting a Lake Stevens siding replacement proposal. A contractor can assess how each window meets the exterior wall and explain what changes when the siding comes off.
Start with the windows that give you trouble
Give each window a name you can use in a conversation, such as “upstairs bedroom facing the yard.” Note whether it opens, closes, and locks as expected. Record where you see visible damage or moisture, and take a picture from a safe place. If a mark appears after wind-driven rain, note the timing and the wall it appeared on. A dated photo gives the contractor something to compare if the mark dries before the visit.
Describe what you see as specifically as you can. Fog trapped between panes, condensation you can wipe away, and a wet mark on the wall below the window are different observations. Ask whether the issue warrants a closer look at the glass, the window unit, or the wall and trim around it.
Sort the openings into three groups
- Plan to keep. The window works well and you want to retain it. Ask how the new exterior trim and weather protection will meet the existing unit. Confirm which finishes and interior surfaces will remain in place.
- Evaluate before deciding. A recurring stain, deteriorating trim, or a window that binds warrants a closer look. Ask what can be assessed now and what may only be visible after the surrounding siding or trim is removed.
- Plan to replace. You already want a different window, or a contractor recommends replacement based on the unit’s condition. Discuss the proposed window size and operation, how it will fit the opening, and which interior and exterior finishes are included.
Bring the list when you discuss window replacement options. For example, an upstairs bedroom window that works well may stay on the first list, while the kitchen window that binds and shows visible frame damage belongs on the evaluation list until the contractor has seen it.
Work through a few common window decisions
A kitchen window is hard to reach
If opening the window means leaning across a deep counter, try the proposed handle or crank at a showroom. Ask where the screen will sit and which way the sash will move. Walk around to the outside and look at what the open window could swing over, such as a deck path, planting bed, or hose connection. These details can help you choose a style while keeping the existing opening size under consideration.
One window needs work on a wall with matching windows
Take a straight-on photo of the whole wall. Compare the proposed frame color, visible frame width, and grille pattern with the windows beside it. Ask to see a frame sample against the planned exterior trim and siding. If there is a visible difference, use the photo to decide whether the new window still works as part of the group. It helps to make that choice before the unit is ordered.

A larger window is on your wish list
Ask for a separate price and scope for changing the opening. Have the contractor explain what the wall assessment needs to cover, what interior repairs could follow, and who will check applicable permit requirements. Ask whether the window size also affects an outside fixture, a cabinet, or the placement of nearby trim.
Clarify the work around windows you keep
Even with a window staying in place, the surrounding trim or details at the opening may be part of the siding scope. Ask the contractor to point out where work will happen and how the existing window, the weather barrier behind the siding, and the flashing that directs water outward will meet. If access is limited, ask what the contractor can confirm before work and how they will review anything unexpected when the opening is exposed.
Decide on the trim appearance with the siding samples in hand. A change in trim width or color can affect how a row of windows looks together. Looking at completed Lake Stevens siding projects can help you describe the finish you want without treating another home’s details as a specification for yours.

Compare proposals by what each opening includes
Two siding estimates can both mention windows and still cover different work. Ask each contractor to identify the windows included and separate the work around retained windows from the cost of new units. Use the same window names on both proposals so you can compare the same opening and spot any missing detail.
- Confirm where work stops. Ask whether the scope includes new casing, drywall patching, paint touch-ups, blinds, or hardware on the inside.
- Agree on how extra work is approved. If the crew finds damaged material when a wall is opened, ask who will document it, price the repair, and get your approval.
- Discuss site access. Ask which rooms the crew will need to enter, when to move furniture or coverings, and how openings will be protected if weather interrupts work.
Look at a Lake Stevens project with one new window
On a completed Lake Stevens siding and window project, KV Construction removed the previous siding and installed primed James Hardie HardiePlank lap siding. The scope included one new window, along with a weather barrier, flashing at openings, and updated exterior trim. It is a local example of including a specific window in a larger siding project.

Leave the consultation with an opening-by-opening plan
For each window, record the decision, the work included around it, and any question that remains. Ask when sizes and styles need to be confirmed if a window will be ordered, and who will handle the interior finish if the scope includes it. Keep photographs with the list so that you can refer to the same opening if a question comes up after removal.

Questions homeowners ask before ordering windows
Can we replace another window later?
Ask how a future installer would reach the window and flashing after the siding is finished. Have the contractor explain which surrounding finishes could need to come off and whether matching pieces can be set aside. That gives you a way to compare the likely work later with the cost of doing it during the siding project.
What if the new window has a different lead time?
Ask when final measurements will be taken and when the order can be placed. If the unit is delayed, discuss whether the crew can work on other walls first and how it will protect any open wall areas. Have the contractor identify which trim and paint steps depend on the window arriving.
