Thinking about replacing those drafty old windows in your Southwest Washington home? You're not alone! Beyond the immediate boost in comfort and curb appeal, did you know that investing in energy-efficient windows can also put money back in your pocket? Thanks to a combination of federal tax credits and generous local utility rebates, 2026 is an excellent year to upgrade.
At LaMoria Construction, we're committed to not just installing beautiful, efficient windows but also helping our clients navigate the financial incentives available. Let's break down how you can save!
Federal Tax Credit: The "Energy Efficient Home Improvement Credit" (25C)
What it is: A tax credit worth 30% of the cost of your new windows and skylights.
The Cap: There's an annual limit of $600 for windows and skylights.
The Catch (and the Opportunity!): This is a per-year cap. If you have a large project, you can strategically replace windows over two calendar years (e.g., front of the house in late 2026, back of the house in early 2027) to claim the $600 credit twice, for a potential total of $1,200!
How to Qualify: Your new windows must meet the ENERGY STAR "Most Efficient" criteria for our Northern climate zone. Don't worry, we can help you select products that meet or exceed these standards.
How to Apply: Keep detailed records and the National Fenestration Rating Council (NFRC) labels from your new windows. When you file your federal income tax return (Form 1040) for the year of installation, you'll use IRS Form 5695, Residential Energy Credits.
Local Utility Rebates: A Southwest Washington Goldmine!
This is where the savings really add up for our local homeowners, especially if your home is primarily heated by electricity (electric furnace, heat pump, or baseboard). Most Public Utility Districts (PUDs) in our region offer fantastic "Weatherization" rebates.
Important Note: Always contact your specific PUD before you start your project! Many require pre-approval or that you use a contractor from their approved network.
Here’s a snapshot of what’s available in Southwest Washington:
Clark Public Utilities (Clark PUD):
Rebate Amount: Between $6.00 to $10.00 per square foot of new window.
Key Requirement: You must work with a contractor from their "Contractor Network". Your windows need a U-factor of 0.30 or lower.
Application: It's fairly straightforward, and we will guide you through the process.
Cowlitz PUD:
Rebate Amount: A solid $8.00 per square foot of new window.
Key Requirement: Cowlitz PUD typically requires an energy audit performed by the PUD before your installation begins. Windows need a U-factor of 0.30 or lower.
Application: Schedule your pre-inspection with Cowlitz PUD first. They'll provide the necessary forms after the audit.
Lewis County PUD:
Rebate Amount: Around $8.00 per square foot of new window.
Key Requirement: Lewis PUD also requires an energy audit performed by the PUD before any work begins. Windows need a U-factor of 0.30 or lower.
Application: Contact Lewis County PUD energy services department for their specific pre-approval process and forms.
Are You a Low-to-Moderate Income Household? Even More Savings Await!
Don't overlook special programs! Many PUDs, like Clark and Lewis PUD, offer "Efficiency Boost" or "Low-Income Weatherization" initiatives. These can significantly increase your rebate amount, sometimes covering a substantial portion – or even the entire cost – of your window replacement project. Always inquire about these programs if they apply to your household.
How to Ensure You Receive Your Incentives: Your Checklist
Contact Your PUD FIRST: This is crucial! Understand their specific requirements, pre-approval processes, and approved contractor lists.
Choose a Reputable Contractor: At LaMoria Construction, we're experienced with all local rebate programs and federal tax credits. We'll help ensure your chosen windows qualify and guide you through the process.
Get a Detailed Quote: Make sure your quote clearly itemizes material costs (for the federal tax credit) and specifies that the windows meet ENERGY STAR criteria.
Save Everything: Keep all invoices, receipts, and especially the NFRC performance labels from your new windows. You'll need these for both tax forms and utility applications.
Submit Promptly: Once your new windows are installed, submit your rebate applications to your PUD as soon as possible, along with all required documentation.
