Replace damaged, outdated, drafty, fogged, or difficult-to-operate windows with properly fitted new units. We plan the work around the existing openings, selected windows, exterior conditions, trim, sealing, and finishing details included in the estimate.

A successful installation involves more than placing a new window in an opening. Depending on the project, the work may include removing the existing unit, preparing the opening, fitting the new window, and completing the agreed flashing, sealing, trim, and finishing details.

Coordinate exterior window and door replacements within one organized remodeling project. This approach creates a consistent plan for removal, installation, exterior repairs, trim work and finishing details, with clear communication throughout the project.
Air movement around a closed window may indicate a problem with the window, its seals, the installation, or the surrounding opening. An on-site evaluation can help identify the visible condition.
Windows that stick, bind, refuse to stay open, or no longer lock properly can become frustrating to use. These problems may result from aging components, damage, movement in the opening, or deterioration around the frame.
Cracked frames, damaged components, deteriorated trim, peeling paint, and moisture-stained areas should be evaluated. The condition around the opening may affect the appropriate installation or repair scope.
Fogging or condensation between panes can indicate that the seal within an insulated-glass unit has failed. This can affect the window’s appearance and performance, although surface condensation may have other causes.

Double-hung windows have two vertically moving sashes that provide flexible ventilation. Their traditional appearance can work with many established and newer home styles.

Casement windows are hinged at the side and open outward with a crank. Their wide opening can provide generous ventilation, while the sash closes firmly against the frame.

Sliding windows open horizontally and can be a practical choice where exterior clearance is limited. Their relatively simple operation and broad glass area work well in many living spaces.

Picture windows use a fixed pane to provide natural light and an open view. Because they do not open for ventilation, they are often combined with operable windows elsewhere in the room.

Awning windows are hinged at the top and open outward from the bottom. Their design provides ventilation while offering some protection against light rain entering through the opening.

Bay and bow windows extend beyond the exterior wall, adding natural light, wider views, and architectural character. Their installation requires careful planning around the existing opening, support, trim, and exterior connections.

The NW Brothers Construction LLC were very professional and efficient AND reasonably priced. They installed 7 new first floor windows in our 103 yr old Hall. They dealt with the many variables that came up with great ideas and helpful options and suggestions. We highly recommend them!!!!


had an excellent experience with NW Brother Construction to change my roof from start to finish. They were professional, responsive, and incredibly easy to work with.


Hired NW Bros to replace all our LP siding, exterior paint, and do some interior repairs. They not only had the best price, but also did an outstanding job. They were punctual and stayed on schedule, even with a few rain days.

From start to finish, from getting an estimate to completing the project, these guys did a GREAT job: installing siding, putting up exterior moldings, and replacing exterior windows and doors with great quality.

The cost depends on the number, size, and style of windows; the selected products; installation access; trim requirements; and the condition of the existing openings. Related siding, flashing, finishing, or dry rot repairs can also affect the scope. NW Brothers provides a written estimate after evaluating the project.
Yes. Replacing one window may be appropriate when the problem is limited to a single unit and the surrounding opening remains suitable. We can evaluate the window and discuss whether a focused replacement is practical for your project.
Yes. Replacing multiple windows together allows measurements, product ordering, access, installation, and finishing work to be coordinated under one project plan. The scope can include a selected group of windows or a larger whole-home replacement.
Visible deterioration around a window should be evaluated before the installation is completed. If damaged wood or other materials are discovered, we explain the condition, discuss the related repairs, and obtain your approval before completing work outside the original scope.
The correct sequence depends on the existing windows, siding, trim, flashing, and the work planned for each exterior wall. When windows and siding affect the same openings, planning the projects together can make it easier to coordinate flashing, trim, exterior repairs, and finishing details.
The timeline depends on the number and type of windows, product availability, accessibility, the condition of the openings, and whether related trim or exterior repairs are required. We provide a clearer schedule after evaluating the home and confirming the proposed scope.
In Oregon, replacing windows without structural changes generally does not require a building permit. Creating a new opening or changing an existing opening’s dimensions typically does. We’ll review the planned work and confirm any applicable local requirements.
Replacement windows may reduce drafts and improve comfort when existing windows are damaged, poorly sealed, or outdated. Actual energy use depends on the existing windows, selected products, installation details, weather, and the overall condition of the home. A specific reduction in energy costs should not be assumed.
