Living in the Pacific Northwest comes with its fair share of weather changes: cold winters, damp springs, and occasional summer heat waves. If you live in an older home in Burlington, Mount Vernon, Sedro-Woolley, or anywhere in Skagit County, chances are your insulation isn’t keeping up.
Many homes built before the 1990s weren’t insulated to today’s standards, and older materials tend to break down over time. So how do you know if your home needs an insulation upgrade? We’ll walk you through the warning signs, explain why insulation degrades, and explore the best modern solutions for older homes.
The first clue that your insulation might be failing is often a change in comfort or rising utility bills. Here are some common issues homeowners in Skagit County notice:
Older homes are more prone to energy loss. Construction codes were different back then, and insulation materials weren’t as effective. If you haven’t upgraded your insulation in the last 20 years, your home may be working harder than it needs to.
There are a few reasons why insulation in older homes stops doing its job:
Insulation is about creating a complete thermal and air seal. That’s why new solutions from insulation contractors today go far beyond the basics.
If you’re not sure whether it’s time to call a professional, here are a few signs that point to the need for an insulation upgrade:
If any of this sounds familiar, it’s a good time to speak with a Mount Vernon insulation contractor like PNW Construction & Energy Services.
Today’s insulation products are more efficient, longer-lasting, and better suited to homes in Skagit County’s climate. Here are the top choices for upgrading insulation in an older home:
Ideal for dense-packing into walls or attics, blown-in cellulose insulation is eco-friendly, fire-resistant, and effective at sealing air leaks when installed correctly.
Spray foam expands to fill every crack and gap, which makes it perfect for crawl spaces, basement rim joists, and hard-to-reach areas. It acts as both insulation and air sealant.
Updated fiberglass insulation is a great choice for attics, especially when installed with a vapor barrier to prevent moisture buildup. Newer batts are safer and more effective than older versions.
No matter the material, professional installation is key. Air sealing, proper ventilation, and moisture control all play a role in maximizing energy savings and avoiding future problems.
Upgrading insulation is a smart long-term investment. Here are the main benefits:
Many insulation upgrades pay for themselves within just a few years, thanks to energy savings and local rebate programs available throughout Washington State.
