Understand the cost of complete siding replacement in Hillsboro, including tear-off, hidden rot repair, waterproofing, James Hardie siding, trim, and exterior painting.
If you are planning to replace the siding on your Hillsboro home, one of your first questions is probably: How much will the entire project cost?
For many Hillsboro homes, a professionally completed full siding replacement may fall within a broad planning range of approximately $20 to $34 per square foot of wall area installed. However, that is only a general starting point—not a quote. The final price depends on the size and design of the home, existing siding, demolition requirements, access, trim details, product selections, painting, and any concealed water or structural damage discovered after tear-off.
The lowest initial number is not always the lowest long-term cost. A complete siding project should protect the wall assembly behind the exterior—not simply cover the house with new boards.
Elite Home Exteriors NW provides complete siding replacement throughout Hillsboro and Washington County. As a James Hardie Elite Preferred Contractor, we focus on proper tear-off, concealed damage repair, weather-resistant barriers, flashing, trim, siding installation, caulking, and exterior finishing.

Every home is different, so siding should not be priced from the home’s interior square footage alone. Contractors generally need to evaluate the exterior wall area, number of stories, gables, windows, doors, rooflines, access, demolition requirements, and finish details.
For early budgeting, Hillsboro homeowners can use these broad project categories:
The most accurate price comes from an on-site inspection and a written proposal based on the actual exterior. You can also review our broader Portland and Vancouver siding cost guide for additional planning information.
Two Hillsboro homes with similar interior square footage can have very different siding costs. A simple rectangular one-story house is generally easier to complete than a two- or three-story home with multiple gables, dormers, bump-outs, decks, roof-to-wall intersections, and limited access.
The following factors usually have the greatest effect on the final price.
Siding is based on the amount of exterior surface being covered—not the home’s listed living area. Tall walls, garages, gables, and architectural projections all add material and labor.
Multi-story homes often require additional scaffolding, staging, safety equipment, setup, and labor. Steep slopes, narrow side yards, landscaping, fences, decks, and neighboring structures can also make access more complicated.
Removing vinyl siding is different from removing cedar, engineered wood, T1-11, stucco, EIFS, aluminum, or an older fiber cement installation. Multiple layers, foam backing, heavy materials, and difficult disposal conditions may affect the total.
Elite Home Exteriors NW generally specializes in complete siding replacement rather than small repairs or covering failed siding. Tear-off allows the underlying wall to be inspected before a new system conceals it.
No contractor can see every concealed condition before the existing siding is removed. Hillsboro’s prolonged wet seasons can allow water intrusion to damage plywood or OSB sheathing, insulation, studs, window openings, and other wood components.
Common causes include:
Concealed repairs can change the final total, but damaged material should be corrected before it is covered. Learn more about our approach to dry rot and water damage during siding replacement.
The selected profile, texture, exposure, and layout all influence pricing. A straightforward lap-siding design is generally less labor-intensive than a home combining multiple products and patterns.
Popular options include:

Trim is a major part of a finished exterior. The number and size of windows, doors, corners, belly bands, gable details, columns, utility blocks, and other penetrations affect both material quantities and installation time.
A proposal should clearly explain which trim components are included instead of treating them as an afterthought.
Homeowners can choose factory-finished ColorPlus® products or pre-primed James Hardie siding that is painted after installation.
Field-applied paint provides extensive color flexibility and makes it possible to finish siding, trim, doors, gutters, and other designated components as one coordinated project. ColorPlus® Technology provides a consistent factory-applied finish and can reduce on-site painting requirements.
The better option depends on your design, color preference, project scope, and budget. Read our comparison of James Hardie ColorPlus vs. painted siding.
The visible siding is only one part of the exterior wall system. A lower estimate may omit or minimize important water-management details that are difficult to see once the project is finished.
Depending on the home and approved scope, a complete system may include:

When comparing proposals, compare the complete scope—not only the total at the bottom of the page.
A detailed siding replacement estimate should identify whether it includes:
An unusually low estimate may exclude tear-off, rot repair, flashing, painting, trim, disposal, or other work that later appears as an added cost. Ask each contractor to explain exclusions and allowances in writing.
James Hardie fiber cement commonly costs more upfront than entry-level vinyl siding. However, purchase price is only one part of the decision.
Hardie® siding is designed to resist damage from moisture, pests, weather, and external fire exposure. It also provides extensive options for lap siding, vertical panels, board and batten, shake accents, trim, textures, and colors. James Hardie states that qualifying siding products include a 30-year, non-prorated limited substrate warranty, subject to its current written terms and proper installation.
Traditional wood and cedar can create a beautiful exterior but generally require more ongoing maintenance. Vinyl can have a lower initial cost but may crack, warp, fade, or sustain impact and heat damage. Engineered wood products can also experience swelling or deterioration when water reaches vulnerable edges or penetrates an improperly detailed wall.
The best value is the product and wall system that fits the home, budget, architecture, and long-term maintenance expectations. Visit the official James Hardie website for current product and manufacturer warranty information.
Hillsboro and the Tualatin Valley experience long periods of rain, damp conditions, wind-driven moisture, and limited drying time. Water does not need a large opening to cause trouble. Small failures at windows, doors, rooflines, utility penetrations, decks, and trim transitions can repeatedly direct moisture behind the exterior.
That is why new siding alone cannot correct every problem. The condition of the sheathing, weather-resistant barrier, flashing, trim transitions, and penetrations matters just as much as the product visible from the street.
A complete tear-off provides an opportunity to:
Our Hillsboro siding contractor page explains how these systems work together on local homes.
The pricing factors are similar throughout Hillsboro, but the homes and site conditions can vary significantly by neighborhood.
Homes may include multiple siding profiles, detailed trim, narrow access points, and modern architectural features. Townhomes and multi-family properties can also require coordinated planning and larger-scale access systems.
Many established homes have aging cedar, engineered wood, T1-11, or vinyl siding. The condition of the original weather barrier and window flashing becomes especially important during replacement.
Two-story designs, gables, dormers, and decorative elevations can increase exterior wall area and installation complexity even when the home’s interior square footage appears average.
Newer construction does not automatically eliminate siding concerns. Installation details, transitions, penetrations, product selection, and exposure still determine how well an exterior manages moisture over time.
Older houses may require lead-safe work practices, careful demolition, additional sheathing repairs, and customized trim details. Elite Home Exteriors NW is a Lead-Based Paint Abatement Certified Siding Contractor for projects where lead-painted materials may be present.
We also serve nearby communities throughout our Oregon siding service area, including Beaverton, Aloha, Tanasbourne, Cornelius, Forest Grove, Banks, North Plains, Tigard, and the greater Portland metro area.
Homeowners can control some project costs without sacrificing the parts of the system that protect the house.
Consider these practical options:
Avoid reducing cost by eliminating necessary flashing, weather barriers, rot repair, proper fasteners, or manufacturer-required installation details. Those components are difficult and expensive to correct after the siding is installed.
Complete siding replacement can improve much more than curb appeal. It creates an opportunity to inspect and correct concealed problems, improve the exterior’s water-management details, reduce recurring maintenance, and modernize the home’s appearance.

The home’s living area does not equal its siding area, so a reliable price cannot be calculated from 2,000 square feet alone. The contractor must evaluate exterior wall measurements, stories, gables, openings, access, siding materials, trim, painting, and concealed conditions. An on-site inspection is the best way to establish an accurate scope.
The amount varies widely. Some homes require only limited sheathing replacement, while others have damage around windows, decks, roof intersections, or framing. Your proposal should explain the included allowance and how additional repair work will be documented and approved.
Installing over old siding can conceal failed flashing, damaged sheathing, moisture intrusion, and other problems. A complete tear-off is often the better approach when the existing exterior has failed or the condition of the wall system is uncertain.
Many residential projects take approximately one to several weeks, depending on the home’s size, architectural complexity, weather, painting requirements, access, and the amount of concealed repair work discovered after removal.
Not always. Primed siding generally requires a field-applied finish, while ColorPlus® products arrive with a factory-applied finish. Ask whether the estimate includes preparation, caulking, primer where needed, siding paint, trim paint, doors, gutters, and other designated surfaces. Learn more about our exterior painting services.
Yes. James Hardie fiber cement is a strong option for Western Oregon because it resists rot, pests, moisture-related damage, and combustion while providing extensive design flexibility. Correct installation, flashing, clearances, and water management remain essential.
