NW Brothers provides professional siding repair, installation and replacement for homeowners throughout Portland. We inspect the condition of your siding, trim and visible exterior transitions before recommending an appropriate scope of work.

A focused repair may be appropriate when the damage is limited and the surrounding siding remains in serviceable condition. Repairs may involve replacing damaged boards or panels, correcting loose sections, addressing failed trim or improving vulnerable transitions.

NW Brothers can also install siding as part of qualifying additions, exterior remodels or new construction projects. The siding is coordinated with the roof, windows, doors, flashing and drainage system to help create a complete and properly integrated exterior.

When siding has widespread deterioration, recurring moisture problems or significant underlying damage, full replacement may provide better long-term value than repeated repairs.
Cracks, warping, rot or holes may indicate siding deterioration or moisture-related damage that should be evaluated.
Poor insulation from damaged siding can cause higher heating and cooling costs.
Moisture behind the siding can contribute to mold and deterioration and may indicate a problem with the siding or surrounding water-management details.
Faded, outdated siding hurts curb appeal and home value. Replacing it improves your home's look.

James Hardie® siding provides the appearance of traditional wood with the durability and lower maintenance of fiber cement. It resists damage from moisture, pests and fire, making it a practical option for Portland homes exposed to frequent rain and changing weather.

Vinyl siding can provide a cost-conscious, low-maintenance exterior with a broad range of colors and profiles. It does not require painting, but product quality, appearance and durability vary between manufacturers.

Engineered wood siding provides a wood-inspired appearance with products designed for improved strength and consistency. It is available in lap siding, panels, shakes and other profiles.

Cedar siding offers a natural appearance that works well with many Northwest architectural styles. It can be installed in lap, shake, shingle or board-and-batten profiles.

Metal siding can provide a clean, modern appearance and strong resistance to moisture, insects and fire. Available options may include vertical panels, horizontal profiles or architectural accent systems.

Complete your siding project with coordinated window and door trim, corner boards, band boards, shake accents and other architectural details. We match these elements with the siding material and exterior design of the home.
Choosing between siding repair and replacement depends on more than the age or appearance of the material. The right recommendation should consider the location and extent of the damage, moisture intrusion, the condition of the underlying wall assembly, previous repairs and whether matching replacement material is available.
A repair may be appropriate when the problem is isolated and the surrounding system remains sound. Replacement may make more sense when deterioration is widespread, water has reached the materials underneath or the siding no longer provides consistent protection.

Dry rot or water-damaged material should be addressed before the area is covered with new siding. If concealed damage is discovered after siding removal begins, NW Brothers will evaluate the affected area, explain the recommended repair and discuss any necessary changes to the project scope before proceeding. Repairing the underlying damage helps provide a stable surface for the new weather barrier, flashing and siding.
The cost depends on the size and design of the home, existing siding, selected material, trim details, access requirements and the condition of the wall underneath. Dry rot or concealed water damage may also affect the scope. NW Brothers provides free siding estimates based on the property, material options and work required.
Fiber cement, engineered wood, vinyl, cedar and metal can all be used on Portland homes. The right material depends on the home’s design, budget, desired maintenance and exposure to moisture. Regardless of the material, proper flashing, trim and water-management details are important for siding exposed to Portland’s rainy climate.
Yes. NW Brothers installs James Hardie fiber cement siding for qualifying projects. It provides the appearance of traditional siding with strong resistance to moisture, pests and changing weather conditions. James Hardie siding is available in different profiles, textures and colors, allowing homeowners to coordinate the material with the architectural style of their home.
The timeline depends on the size of the home, complexity of the exterior, selected material and amount of preparation required. Weather, material availability and concealed damage can also affect the schedule. After evaluating the property and planned scope, NW Brothers can provide a more accurate timeline for the siding project.
Siding projects can be completed during much of the year, but heavy rain and other weather conditions may affect scheduling. The exposed portions of the home must be managed carefully throughout installation.
Siding alone does not determine a home’s energy performance, but the project may provide an opportunity to address gaps, weather barriers or insulation included in the agreed scope. The improvement depends on the existing wall assembly and selected materials.
Move outdoor furniture, decorations and other belongings away from the exterior walls. Because installation can create vibration, it is also helpful to remove fragile items from interior walls and provide clear access around the home.
