Spray Foam Insulation
Contractor Portland, OR
Vale Insulation works as a spray foam insulation contractor for Portland area homes and buildings, applying closed cell spray foam anywhere standard batt or blown-in insulation doesn't hold up well on its own. That includes attics with irregular framing, crawl spaces dealing with ongoing moisture, additions, and rim joists where air leaks are hardest to stop any other way. Spray foam insulates and air seals in a single step, which makes it one of the more effective options available, but only when it's installed correctly.
The Spray Foam Insulation Contractor Portland Homeowners Trust
We've been installing spray foam across the Portland area for over 20 years, in attics, crawl spaces, and additions, either on its own or alongside other insulation work. It's not simple material to work with. It expands as it's applied, so a rushed or untrained install leaves gaps, uneven coverage, or overspray that ends up costing more to fix later. Doing it right the first time matters.
Signs You May Need Spray Foam Insulation
A room that's always too hot or cold no matter the thermostat setting
Noticeable drafts around outlets, rim joists, or hard to reach framing
An attic or crawl space with irregular framing that batts or blown-in can't fully cover
Rising energy bills with no clear explanation
An addition or remodel where standard insulation doesn't fit the space well
A crawl space dealing with ongoing moisture or airflow issues
An inspector or contractor recommending a higher R-value than what's currently installed
What Our Spray Foam Insulation Process Looks Like
We start by evaluating the space and figuring out where spray foam actually makes sense versus where it doesn't. From there we prep the area, apply closed cell spray foam in layers so it cures properly, trim any excess once it's set, and inspect the coverage closely, especially around penetrations like wiring, plumbing, and can lights, since that's where gaps tend to hide.
Why Spray Foam Insulation Matters in Portland Homes
A lot of Portland homes were built to insulation standards that are well below today's code, and older houses in particular tend to have drafty, hard to seal areas that regular insulation struggles with. Combine that with our wet winters, and crawl spaces especially need something that handles moisture and air sealing at the same time. Spray foam's higher R-value per inch also matters in tight spaces where there isn't room to add a thick layer of anything else.
Attic Spray Foam vs. Crawl Space Spray Foam
Attic spray foam insulation is usually about maximizing R-value in limited depth and sealing tightly around penetrations like can lights, vents, and wiring to stop heat loss through the roof deck.
Crawl space spray foam insulation is more about moisture and air sealing at the rim joist and foundation walls, since crawl spaces see constant dampness and are one of the biggest sources of cold, drafty floors.
Either way, the goal is complete coverage without gaps that undermine the whole job.
Common Reasons We're Called for Spray Foam Insulation
A room or addition that never seems to hold temperature
An older home with minimal or settled original insulation
A remodel with irregular or hard to reach framing
A crawl space with persistent moisture or drafts
A homeowner wanting to maximize R-value without losing a lot of space
This doesn’t mean that spray foam is always the right call. It costs more per square foot than batt or blown-in insulation, and for a straightforward attic with normal framing, another product can often do the job just as well for less. Part of a real evaluation is telling you when spray foam is worth the investment and when it isn't. We'd rather recommend the right product than the most expensive one.

Frequently Asked Questions
Is spray foam insulation worth the extra cost?
01
It depends on the space. In tight, hard to reach areas or additions with irregular framing, the higher R-value per inch and air sealing properties often make it worth it. For a standard attic with normal framing, blown-in or batt insulation can perform just as well for less money. We'll walk you through the tradeoffs during your evaluation.
Can spray foam be added to an existing home, or is it only for new construction?
02
It can be added to an existing home. It's commonly used in crawl spaces, attics, additions, and remodels where walls are already open. The space just needs to be accessible and, in most cases, cleared of old insulation first.
