Window Replacement
New windows should do more than look clean from the street. They should operate easily, reduce drafts and manage water at every opening. We replace the window as part of the wall—checking the sill, framing, flashing, air sealing, trim and surrounding exterior before the finished work hides the details.

More than glass and a frame
The glass is only one part of the opening.
A window interrupts the drainage plane and creates four corners where small errors can become leaks. The sill pan, jamb and head flashing, water-resistive barrier, perimeter seal and exterior trim all have jobs to do.
Replacement is the opportunity to inspect the opening and rebuild weak transitions before the new window and trim cover them again.
Open enough to understand the opening
We look for sill damage, out-of-square framing and weak transitions that should not be hidden behind the new unit.
Build drainage from sill to head
Sill-pan, jamb and head flashing are layered with the weather barrier so incidental water has a path down and out.
Set the unit for operation and air sealing
The window is supported, shimmed and installed plumb and square, then sealed around the frame without distorting it.
The right replacement approach
Open the wall only as far as the project needs—but far enough to do it right.
A full-frame replacement provides the best access to the opening and flashing. An insert can be responsible when the existing frame and water-management details are sound. We explain the tradeoff before recommending either.
Our preferred corrective approach
Full-Frame Window Replacement
The existing frame and trim are removed so the rough opening, sill and flashing can be inspected and rebuilt. This is the clearest path when leaks, rot or weak exterior details are part of the problem.
Existing frame and affected trim removed
Opening and concealed conditions evaluated
Sill pan and flashing integrated with the wall
New interior and exterior trim coordinated
For select sound openings
Insert or Pocket Replacement
An insert can preserve the existing frame and limit finish disturbance when that frame is sound, square, dry and compatible with the new unit. Its limitations should be clear before work begins.
Existing frame is structurally sound
No unresolved moisture or sill concerns
Opening size and operation remain suitable
Reduced glass area and flashing access considered
The goal is not to disturb more of the house than necessary. It is to expose enough of the opening to understand its condition, manage water correctly and leave a window that operates and seals as intended.
A complete window opening
What determines whether replacement windows perform.
Glass packages and frame materials matter, but no window can correct a damaged sill, careless flashing, weak air sealing or a frame installed out of square.
Opening, framing and concealed damage
Soft sills, swollen sheathing and out-of-square framing are addressed before the new window covers the opening.
Sill pan and lower corners
The sill is sloped or detailed to drain, with a continuous pan and protected corners where water is most likely to collect.
Jamb and head flashing
Side and head flashing are integrated in shingle fashion with the water-resistive barrier so upper layers drain over lower ones.
Support, shims and operation
The frame is supported at the correct locations and installed plumb, level and square so sashes move and lock without binding.
Perimeter air sealing
The gap around the frame is sealed and insulated without bowing the unit, reducing drafts while preserving correct operation.
Exterior trim and siding integration
Trim profiles, clearances, sealant joints and siding transitions are planned as part of the opening instead of patched afterward.
Rochester, WA exterior project
Windows have to belong to the wall around them.
This Rochester remodel shows the window in its real context: surrounded by siding and trim, exposed to roof runoff and tied into the wall’s drainage plane. Coordinating those materials is what makes the exterior look intentional and perform as one system.

Choose with context
Performance starts with the opening, then the window.
The right window depends on exposure, ventilation, maintenance, room use and the way it needs to meet the existing exterior. These decisions are more useful than chasing one headline efficiency number.
Exposure and orientation
Wind-driven rain, direct sun, roof overhangs and the direction a window faces affect glass, frame and installation decisions.
How the window should operate
Casement, awning, single-hung, double-hung and sliding units ventilate and clean differently. Room use should guide the choice.
Ventilation and egress
Bedrooms, kitchens and hard-to-reach openings may have ventilation, access or emergency-exit needs that affect size and operation.
Glass and energy performance
Low-E coatings, U-factor, solar heat gain and pane configuration should be considered with the room and orientation, not as isolated numbers.
Frame material and maintenance
Vinyl, fiberglass, clad and wood options balance cost, durability, profile, color and maintenance differently.
Interior and exterior finish
Casing, stools, drywall returns, exterior trim and siding transitions affect both the budget and how complete the replacement feels.
Not every old window needs to be replaced at once, and not every draft begins at the glass. We help separate product problems from installation, air-sealing and wall conditions before defining the scope.

Common questions
What homeowners usually want to know.
The exact answer depends on the opening, existing wall and selected window, but these are useful starting points before an inspection.
What is the difference between full-frame and insert replacement?
Full-frame replacement removes the existing frame and exposes the rough opening for inspection and flashing. An insert fits inside a sound existing frame, limiting disturbance but also limiting access and slightly reducing glass area.
Do all the windows in the house need to be replaced at once?
Not necessarily. Age, leakage, operation, room priorities and exterior access can support a phased plan. We help identify which openings are urgent and which can remain in service.
Will new windows lower my energy bills?
Efficient glass and tighter frames can help, especially when existing units leak air or have failed seals. Actual savings depend on the home, installation, insulation, heating system and how the windows are used.
What happens if you find rot around a window?
The damage and its moisture source are documented and explained before the repair scope expands. New windows should not cover an unresolved sill, sheathing or flashing problem.
Which window frame material is best?
There is no universal answer. Vinyl can be practical and efficient, fiberglass offers strength and stability, and clad or wood options provide different profiles and finishes. Exposure, design, maintenance and budget should guide the choice.
How long does window replacement take?
Timing depends on the number of openings, product lead time, access, trim and finish work, concealed repairs and whether the project uses full-frame or insert installation. We set expectations from the actual scope.
