Window Styles
Explore common residential window styles.
Window style affects operation, ventilation, appearance, hardware, glass area, and how the unit fits the existing opening. Select a style below for more detail.
Double-Hung Windows
Two vertically operating sashes provide a traditional residential window configuration with upper and lower ventilation options.
Casement Windows
Hinged windows that open outward and are commonly operated with a crank, available as individual units or in larger combinations.
Sliding Windows
Horizontal sliding windows are commonly used in wider residential openings where one or more sashes move along the frame.
Bay & Bow Windows
Projecting window assemblies that extend beyond the exterior wall and may involve support, flashing, trim, roofing, and opening work.
Window Replacement
Replacement of existing windows using the appropriate installation approach based on the opening, frame, sill, trim, flashing, and surrounding conditions.

Window installation for new openings, additions, renovations, and projects where the wall assembly is opened for full installation.

The existing opening determines the installation approach.
Not every replacement window project requires the same scope. The condition of the existing frame, flashing, trim, sill, and surrounding exterior helps determine the right approach.
An insert or pocket replacement may be appropriate when the existing frame is suitable to remain and the new window can be installed within it.
A full-frame replacement removes the existing window and frame to expose the rough opening, allowing the opening, flashing, sill, and surrounding materials to be evaluated.
For more detail, see our window replacement and new-construction window pages.
Replacement Windows
Existing openings are evaluated to determine the appropriate replacement approach and required surrounding work.
Replacement details →New-Construction Windows
Used where the wall assembly is opened, a new opening is created, or the project requires full integration with exterior wall materials.
New-construction details →Installation Details
Flashing and weatherproofing are part of the complete window opening.
A window installation involves more than the window unit itself. Existing wall conditions, flashing, sealing, exterior transitions, trim, and manufacturer requirements all affect the finished opening.
Window Flashing
Water ManagementWindow flashing work can include sill, jamb, and head-flashing details coordinated with the window, wall assembly, exterior cladding, and approved installation.

Sealing & Exterior IntegrationWeatherproofing can involve sealing, insulation, exterior transitions, trim details, and other work around the opening depending on the existing conditions and approved scope.

How a window project works with OJB.
The exact process depends on the window system and existing conditions, but most replacement projects follow these steps.
On-Site Estimate
We measure openings, evaluate the existing windows and visible frame conditions, discuss styles and goals, and define the proposed scope.
Window Selection
Window style, frame material, glass package, color, operation, and other approved project details are finalized before ordering.
Removal & Opening Prep
The existing window is removed according to the approved scope and the opening is checked for conditions that need to be addressed before the new unit is installed.
Install, Seal & Finish
The replacement unit is installed, flashed or sealed as required by the approved system, trimmed, adjusted, and reviewed before closeout.

Window FAQ
Common window replacement questions.
Replacement windows are installed into an existing window opening using the appropriate replacement method. New-construction windows are commonly used when the wall assembly is opened, a new opening is created, or full integration with exterior wall materials is part of the project.
OJB Solutions installs several residential window styles including double-hung, casement, sliding, and bay or bow window systems, depending on the opening and selected product.
Fog or condensation between panes often indicates a failed seal in the insulated glass unit. The appropriate solution depends on the window system, frame condition, and available replacement options.
Flashing is part of how the window opening integrates with the wall and exterior materials. The required details depend on the window type, wall assembly, siding, existing conditions, and installation method.
Potentially. We can evaluate visible sealing, trim, flashing, exterior transitions, and other conditions around the opening to determine an appropriate scope.
Permit requirements depend on the property, jurisdiction, and scope. Structural changes, changes to an opening, or other modifications may have different requirements than a straightforward replacement. When permits are required for work in our scope, OJB Solutions coordinates the applicable process.
Yes. Window projects can range from individual units to larger multi-window or whole-home replacement projects.
Visible damage is included in the proposed scope whenever it can be identified beforehand. If concealed conditions are discovered during removal, we explain what was found and document any required scope change before additional work proceeds.
