Heat rises - and if your attic is under-insulated, it escapes right through the ceiling. Proper attic insulation keeps warmth where it belongs and cuts your monthly bills.

Old batts settle and leave cold spots over time. Blown-in material fills every corner and odd-shaped space, restoring consistent coverage across your entire attic floor.

Drafty rooms and high heating bills point to the same root cause: insulation that is not doing its job. A full home assessment finds where you are losing heat and fixes it.

Damaged, wet, or pest-contaminated insulation does more harm than good. Safe removal clears the way for new material that actually protects your home.

Cold floors and moisture problems almost always start in the crawl space. Insulating the floor joists and sealing the space makes your whole house feel different.

Walls without insulation let cold air work right through them. Adding insulation to existing walls - without a full renovation - dramatically improves comfort in older homes.

Insulation slows heat loss, but air sealing stops it. Closing gaps around pipes, fixtures, and framing can cut your heating and cooling costs more than adding insulation alone.
Learn MoreReach out by phone or through our contact form. We will ask a few basic questions about your home and what you have been noticing - cold floors, high bills, drafts. You do not need to have all the answers ready. We respond within 1 business day and schedule a free on-site visit at a time that works for you.
We come to your home and take a look at the attic, crawl space, or whatever area is giving you trouble. We check what is already there, look for air leaks and moisture issues, and measure the spaces that need work. You get a written estimate with clear recommendations - no pressure, no upsell. This visit is free and takes 30 to 60 minutes.
Once you approve the scope, we schedule the job and show up on time with everything we need. Most insulation jobs are completed in a single day. We do a walkthrough before we leave so you can see the finished work yourself. Most homeowners notice improved comfort within the first few weeks of the next heating season.
We hold a valid Oregon Construction Contractors Board (CCB) license and carry full liability coverage on every project. You can verify our license before you hire us - we provide the number on request.
We are a local company - not a franchise, not a national chain. We live and work in Corvallis and serve the same communities we are part of. When you call, you reach someone local, not a call center.
Every estimate starts with a free visit to your home. We look at the actual conditions - not a photo or a square-footage number over the phone - before we quote you anything. No pressure to commit, no fee for the visit.
Submit a request today and you will hear back from us within 1 business day. We do not leave voicemails sitting for a week. If we cannot pick up, we call back the same day or the next morning.

"The crew was at my house when they said they would be, finished the attic in one day, and left the place clean. The difference in how the upstairs rooms feel this winter has been noticeable - no more freezing bedrooms in January."
Brian T., Albany - Attic insulation
"I had been putting off the crawl space for years because I dreaded the whole process. It turned out to be much easier than I expected. They handled everything, explained what they found down there, and my floors have felt warmer ever since."
Melissa R., Corvallis - Crawl space insulation
"Called on a Tuesday, had an estimate by Thursday, and the spray foam was done the following week. They walked me through the whole job before they left and even helped me understand the Pacific Power rebate I qualified for."

If your home was built before 1980 and the insulation has never been touched, the answer is almost always yes. Homes from that era were built to standards far below what Oregon requires today. The return on a good attic or crawl space upgrade is real and measurable.
In a wet climate like the Willamette Valley, insulation that traps moisture becomes less effective over time and can contribute to mold and rot. Pairing insulation with proper air sealing and vapor control is not optional here - it is essential. The U.S. Department of Energy has guidance on managing moisture in homes at{' '}energy.gov.
Both matter, but in different ways. Insulation slows heat transfer. Air sealing stops air movement, which is responsible for a large share of actual heat loss. A well-insulated home that is not air-sealed will still lose significant energy through gaps. The best jobs do both.
Cold floors in winter are the most common sign. If you walk across your living room in socks and the floor feels noticeably cold despite the heat running, the crawl space is the first place to look. Moisture, musty smells, and condensation on pipes are also strong signals.
In most cases, yes. Blown-in insulation can be added to an attic in a single morning without touching the rest of your home. Retrofit wall insulation can be done with small access holes that are patched and painted. You do not need to tear out drywall to upgrade insulation in an existing home.
For attics in the Pacific Northwest, the Department of Energy recommends a total R-value between R-49 and R-60 - roughly 15 to 19 inches of blown-in insulation. If you can see the tops of the wooden framing boards in your attic, you are well below that level. Learn more at ENERGY STAR.
Corvallis Insulation Company is a licensed and insured insulation contractor based in Corvallis, OR, serving homeowners and commercial property owners across 12 communities in the Willamette Valley since 2025.
We hold a valid Oregon Construction Contractors Board (CCB) license, which is the state-issued credential required to legally perform insulation and weatherization work on residential and commercial buildings in Oregon.
We offer 16 insulation and air sealing services and serve 12 cities across the Willamette Valley and coast. Every project starts with a free on-site estimate and ends with a walkthrough so you know exactly what was done.
If insulation is visibly wet, compressed, or showing signs of pest activity, it needs to come out before new material goes in. Old insulation does not improve with age - it settles and loses coverage.
Air leaks account for a large share of heat loss in most homes. Adding insulation on top of a leaky envelope slows heat transfer but does not stop air movement. You will see some improvement, but not nearly what you paid for.
Not always. Spray foam is the most thorough option but also the most expensive. Blown-in cellulose or fiberglass is often the right call for a standard attic upgrade. The right material depends on the space, the moisture conditions, and your budget.
Basic blown-in attic insulation is available as a DIY project at most home centers. Spray foam, crawl space encapsulation, and anything involving moisture or structural concerns is best left to a licensed contractor.

Corvallis is a mid-sized city of about 59,000 people in the heart of the Willamette Valley, anchored by Oregon State University, which is by far the largest employer in the area. The city sits along the Willamette River, and its riverfront parks and trails are a daily part of life for many residents. A large share of the housing stock was built between the 1940s and 1970s - homes that were never designed with today's energy standards in mind and often need meaningful insulation upgrades to perform properly.
Corvallis gets close to 50 inches of rain per year, with the bulk of it falling between October and April. That long, wet season puts persistent pressure on crawl spaces, attics, and exterior building envelopes. Homes near the OSU campus and in the older South Corvallis neighborhoods tend to have the most pressing insulation needs, while newer subdivisions on the north side of town are now entering the phase where first major upgrades make sense. The Corvallis Farmers Market community runs from April through November, and the broader region is defined by a stable, educated population that takes home maintenance seriously.
Corvallis Insulation Company operates out of Corvallis and works throughout the surrounding region - from Albany and Lebanon to the east, to Newport on the coast, to Salem and McMinnville to the north. We know the housing stock here, we understand what the climate demands, and we show up with the right equipment for the job. If you are a Corvallis homeowner dealing with cold floors, high heating bills, or a crawl space you have been avoiding, we are the right call.
