Siding replacement is one of those projects that homeowners put off until they absolutely can’t ignore it anymore. Maybe you’ve noticed warping boards, moisture getting behind the siding, or your home just looks tired and outdated. Whatever the reason, you’re probably wondering: what’s this actually going to cost me?
The short answer? For most homes, you’re looking at anywhere from $8,000 to $30,000 or more, depending on your home’s size, the material you choose, and how complex the job is. But let’s break down what really drives those numbers and what you should expect when budgeting for this major home improvement.
What Affects the Cost of Siding Replacement?
Home Size and Square Footage
The most obvious factor is how much siding your home needs. A 1,500 square foot ranch will cost considerably less than a 3,000 square foot two-story. Contractors typically price siding by the square foot, so knowing your home’s exterior square footage is the first step in getting an accurate estimate.
Keep in mind that your exterior square footage is different from your home’s interior living space. Exterior measurements account for wall height, gables, and other architectural features that add to the total surface area.
Siding Material Choice
Your material choice makes the biggest impact on your final cost. Here’s a breakdown of common siding materials and what you can expect to pay:
Vinyl Siding Vinyl remains the most budget-friendly option, typically running $3 to $8 per square foot installed. It’s low-maintenance, comes in many colors, and holds up well in Oregon’s wet climate. While some homeowners worry vinyl looks “cheap,” modern vinyl siding has come a long way in replicating the look of wood and other premium materials.
Fiber Cement Siding (James Hardie) Fiber cement, like the James Hardie products we install, costs more upfront, usually $8 to $14 per square foot installed. But there’s a reason it’s our most popular recommendation. It won’t rot, resist pests and fire, and can last 50+ years with minimal maintenance. For Portland-area homes dealing with rain and moisture, fiber cement is hard to beat.
Wood Siding Natural wood siding runs $8 to $15 per square foot installed. It offers beautiful, authentic character but requires regular maintenance, staining, painting, and treating to prevent rot. In our climate, you’ll need to stay on top of upkeep or face expensive repairs down the road.
Engineered Wood Engineered wood products give you the look of real wood with better moisture resistance, typically costing $6 to $12 per square foot installed. It’s a middle-ground option that works well for homeowners who want wood’s aesthetic without all the maintenance headaches.
Aluminum and Steel Metal siding ranges from $5 to $11 per square foot installed. It’s durable and fire-resistant but can dent and isn’t always the most attractive option for residential homes.
Architectural Complexity
A simple box-shaped home costs less to side than one with multiple stories, dormers, peaks, and intricate trim details. Every corner, window cutout, and design feature adds time and material, which increases labor costs. Two-story homes also require scaffolding or lift equipment, adding to the expense.
Old Siding Removal and Disposal
If you’re replacing existing siding (and not building new construction), your contractor needs to tear off and dispose of the old material. Removal typically adds $1 to $2 per square foot to your project cost. In some cases, if there’s damage underneath the old siding, like rotted sheathing or water damage, you’ll need repairs before new siding goes up.
Labor Costs in Your Area
Labor rates vary significantly depending on where you live and the contractor’s experience level. In the Portland Metro area, expect to pay higher labor rates than rural Oregon markets, but you’re also getting skilled tradespeople familiar with local building codes and weather considerations.
Permits and Building Codes
Most municipalities require permits for siding replacement projects. Permit costs vary but typically run a few hundred dollars. Working with an experienced contractor ensures your project meets all local codes and passes inspection the first time.
Hidden Costs to Plan For
Beyond the basic material and labor, here are a few additional expenses that can catch homeowners off guard:
House Wrap and Moisture Barriers Proper installation includes a weather-resistant barrier behind your siding. This protective layer is essential in Oregon’s rainy climate and typically adds $0.50 to $1.50 per square foot.
Trim and Finishing Details New siding often means replacing trim around windows, doors, and corners. Quality trim work enhances your home’s appearance but adds to the overall cost.
Insulation Upgrades If your home lacks adequate insulation, siding replacement is a great opportunity to add it. Insulated siding or adding foam board insulation increases upfront costs but can significantly improve energy efficiency and lower heating bills.
Unexpected Damage Once the old siding comes off, contractors sometimes discover hidden issues, rot, mold, or structural damage that needs repair before new siding goes on. Building a 10-15% contingency into your budget helps cover these surprises.
How to Get the Most Value from Your Siding Investment
Don’t Choose Based on Price Alone
The lowest bid isn’t always the best deal. Inexperienced contractors cutting corners can leave you with poor installation, warranty issues, and premature failure. Focus on quality workmanship, proper installation techniques, and a solid warranty.
Consider Long-Term Costs
A cheaper material might save money upfront but cost more over time in maintenance and repairs. Fiber cement siding, for example, has a higher initial cost than vinyl but requires virtually no maintenance and lasts decades longer.
Get Multiple Quotes
Get at least three detailed estimates from licensed, insured contractors. Make sure each quote breaks down materials, labor, and other costs so you can make an apples-to-apples comparison.
Timing Can Save Money
Some contractors offer discounts during their slower seasons, typically late fall through early spring in Oregon. Just be aware that winter weather can delay projects or complicate installation.
Invest in Quality Installation
Proper installation is just as important as the material itself. Poorly installed siding, even high-quality fiber cement, can fail prematurely. Choose experienced contractors who specialize in the material you’re installing.
What to Expect: Sample Cost Estimates
Here are rough estimates for different home sizes using fiber cement siding (our most popular material):
- 1,200 sq ft home: $12,000 – $18,000
- 1,800 sq ft home: $16,000 – $26,000
- 2,500 sq ft home: $22,000 – $35,000
- 3,000 sq ft home: $28,000 – $42,000
These ranges include material, labor, removal of old siding, trim, and basic house wrap. Your actual cost will depend on your home’s design, material choices, and any additional work needed.
Why Fiber Cement Makes Sense for Oregon Homes
After years of installing siding in the Portland Metro area, we recommend fiber cement for most homeowners. Here’s why:
It handles our wet climate without rotting or warping. Unlike wood, it won’t attract insects or require constant repainting. It’s non-combustible, a big advantage in an era of increasing wildfire concerns. And it looks great, with authentic textures that replicate wood grain without the maintenance.
James Hardie siding, specifically, comes with one of the best warranties in the industry and has proven its durability in the Pacific Northwest’s challenging conditions.
Financing Options for Siding Replacement
If the upfront cost feels overwhelming, several financing options can help:
- Home equity loans or lines of credit typically offer lower interest rates since they’re secured by your home
- Personal loans don’t require home equity but may have higher interest rates
- Contractor financing through programs offered by manufacturers or lenders
- Energy-efficient financing if your project includes insulation upgrades that improve energy performance
