Serving Roseburg, OR and surrounding areas. (458) 803-7783
Roseburg Insulation is a licensed insulation contractor serving Cottage Grove with retrofit insulation, attic upgrades, crawl space work, and spray foam. Most homes in this area were built before modern energy codes, and we specialize in bringing older Lane County homes up to current performance levels.
Cottage Grove has one of the highest concentrations of mid-20th century homes in Lane County, and the vast majority were built with insulation levels that fall far short of what Oregon energy codes require today. Retrofit insulation is the process of adding or replacing insulation in a home that is already occupied and finished - no major demolition required. Our retrofit insulation services are designed specifically for older wood-frame homes like those throughout Cottage Grove.
Most Cottage Grove homes built before 1980 have attics with compressed, thinned insulation that has lost a significant share of its original R-value over decades. Lane County winters bring persistent damp cold from October through April, and a thin attic lets that cold pour directly into your living space while your heating system runs constantly to compensate. Bringing your attic up to current R-value standards is the most direct way to lower heating costs here.
Cottage Grove homes sit on clay-heavy Lane County soils that drain poorly and keep ground moisture levels elevated well into summer. Crawl spaces under older homes here deal with that moisture cycling every single year, and when the insulation and vapor barrier are original to the 1950s or 1960s, they have usually failed long ago. Insulating and encapsulating the crawl space stops moisture intrusion at the source and eliminates the cold, soft floors that result from it.
Cottage Grove receives close to 50 inches of rain per year, and that water sits in the clay soil under homes long after each storm. Without a properly installed vapor barrier on the crawl space floor, that ground moisture rises into the framing and subfloor above. In a climate this wet, a vapor barrier is not optional - it is the baseline that everything else depends on.
Older wood-frame homes in Cottage Grove have rim joists, wall cavities, and plumbing and wiring penetrations that batts cannot seal. Spray foam expands into every gap it contacts and hardens into a continuous barrier, giving you insulation and air sealing in a single pass. It is particularly well-suited to the crawl space walls and rim joists in homes where moisture has been a recurring issue.
Cottage Grove sits in a region that sees significant wildfire smoke in late summer, and a home with unsealed gaps lets that outdoor smoke in through the same paths that lose heat in January. Air sealing is also what makes any insulation upgrade perform at its rated level - without it, heated air migrates through gaps and the insulation above does only part of its job. We always assess air sealing needs before recommending an insulation scope.
Cottage Grove is a city of about 10,000 people in Lane County, roughly 20 miles south of Eugene along Interstate 5. The area gets close to 50 inches of rain per year, with the bulk arriving between October and April. That wet season is long and relentless, and the clay-heavy soils throughout the Willamette Valley floor drain poorly, which keeps ground moisture under crawl space foundations elevated for much of the year. Most of Cottage Grove's housing was built between the 1940s and 1970s - wood-framed, single-family homes with crawl space foundations and original insulation that was minimal even when it was new. The combination of aging construction and a persistently wet climate means moisture damage in crawl spaces and inadequate attic insulation are the two most common problems we find in homes here. They are also the two problems with the most straightforward fixes.
Summers in Cottage Grove are warm and dry, with July and August highs in the upper 80s and an increasing risk of wildfire smoke in late summer. Freeze-thaw cycles in winter are mild by Oregon inland standards but still put stress on exposed crawl space materials and concrete flatwork over time. A well-insulated and air-sealed home handles both the wet cold of winter and the dry heat of summer more efficiently - and keeps wildfire smoke out through the same envelope that would otherwise lose heat in January. For a city with as much older housing stock as Cottage Grove, bringing homes up to current insulation standards is one of the most practical investments a homeowner can make.
Our crew works throughout Cottage Grove regularly, and we understand the local conditions that affect insulation work here. When permits are required, we work through the City of Cottage Grove Building Department, which handles residential building permits within city limits. Most of the homes we work on here are older wood-frame houses with crawl space foundations, and we know what decades of Lane County moisture does to original vapor barriers and fiberglass batts.
Cottage Grove is known throughout Oregon as the Covered Bridge Capital of the West, and its historic downtown along Main Street is a genuine point of local pride. Whether a home is near the older neighborhoods close to downtown, out near Cottage Grove Lake to the south, or in the newer sections on the edges of the city, the homes we work on here share a common thread - older wood construction that benefits significantly from modern insulation and air sealing.
We serve Cottage Grove alongside neighboring communities in the region. If you are looking for an insulation contractor in Drain to the south in Douglas County, or in Oakland along the I-5 corridor, we cover those communities too.

(458) 803-7783Cottage Grove is a city of about 10,000 people in southern Lane County, situated along Interstate 5 about 20 miles south of Eugene. The city has its own identity, its own downtown, and its own tight-knit community - it is not a suburb of Eugene. Cottage Grove grew out of the timber and mining industries in the late 1800s and early 1900s, and that history is visible in the housing stock, which is dominated by wood-frame single-family homes built during the mid-20th century. The city calls itself the Covered Bridge Capital of the West - there are several historic covered bridges in the surrounding area that draw visitors and are a genuine source of local pride. Cottage Grove Lake to the south, managed by the U.S. Army Corps of Engineers, is a popular recreation spot for residents.
The housing market in Cottage Grove is dominated by owner-occupied single-family homes, with roughly 55 to 60 percent of units owner-occupied according to Census data. Most of the housing inventory is older stock - there has not been a major wave of new subdivision development here the way larger Oregon cities have seen. Homeowners in Cottage Grove tend to invest in their properties because they plan to stay. The mix of in-town lots near the historic downtown and rural or semi-rural properties on the city edges means we work on everything from modest in-town houses to larger parcels with outbuildings. We serve Cottage Grove alongside Drain and Glendale, which face similar older housing conditions along the I-5 corridor.
