If your heating costs keep climbing every winter, your attic insulation may be the culprit. We fill gaps quickly and evenly so your home holds heat the way it should.
Blown-in insulation in Rochester fills your attic, walls, or crawl space with loose material — usually cellulose or fiberglass — that slows heat from escaping in winter or entering in summer. Most attic jobs take two to four hours and you can stay home the whole time.
Rochester homeowners in older neighborhoods like the IBM-era southeast side often have attics with insulation that has settled to a fraction of what it should be. The result is high heating bills and cold spots in upstairs rooms that no thermostat adjustment fixes. Blown-in material flows around joists, wires, and odd-shaped spaces that rigid batts cannot reach — making it the right fit for most existing homes. If your home also has air leaks around fixtures or the attic hatch, combining blown-in with attic insulation and sealing work delivers the best result.
If your gas or electric bill rises every winter without any change in habits, heat is escaping faster than your system can replace it. In Rochester's long, cold seasons the attic is the most common culprit. This is one of the clearest signs the insulation is no longer doing its job.
Ice dams — thick ridges that build at the edge of your roof — are a direct sign that heat is escaping through your attic and melting snow unevenly. Rochester homeowners see this regularly after heavy snowfalls followed by cold snaps. If you have had ice dams, your attic almost certainly needs more insulation and air sealing.
If bedrooms at the top of your house feel drafty or hard to keep warm even with the heat running, the ceiling above them may not have enough insulation. This is especially common in Rochester homes built before the 1980s, where attic insulation was often installed thin or has settled significantly over the years.
Stand under your attic hatch on a cold day and hold your hand near the edges. Cold air seeping in means the attic above is not properly sealed or insulated. The same test works around recessed light fixtures — cold air trickling down is a common sign of an under-insulated attic.
Rochester Insulation uses truck-mounted blowing equipment to deliver loose-fill material precisely where your home needs it. For attics, we blow material in through your hatch until it reaches the correct depth for Minnesota's climate — deeper than most national estimates suggest. We leave depth markers so you can verify the job yourself.
For wall cavities in older homes, we use a denser packing technique that fills the stud bay completely without disturbing your drywall. This is especially useful in Rochester's IBM-era ranch homes where walls were never insulated during construction. When the job also calls for whole-home insulation — covering attic, walls, and basement rim joists in one project — we coordinate the sequence so each area is done right the first time.
We recommend pairing any blown-in project with air sealing when budget allows. Insulation slows heat transfer, but open gaps let heat escape entirely. The combination delivers the biggest drop in heating bills and is the most reliable long-term fix for ice dams.
Best for most Rochester homes — fast, even coverage at the right depth for Climate Zone 6.
Ideal for older homes where walls were never insulated or where batts have shifted.
A firmer fill technique for walls that need to stay put without settling over time.
For homeowners who want to address the whole house in a single scheduled visit.
Rochester sits in a climate zone where average January temperatures regularly drop below 10 degrees Fahrenheit and wind chills push it much colder. Homes here need a substantially thicker insulation layer than homes in the Midwest's milder southern cities. A contractor quoting a Rochester job should be specifying a deeper installation than the national average — and if they are not, that is worth asking about.
A large share of Rochester's housing stock was built during the city's mid-century growth alongside Mayo Clinic and IBM. Neighborhoods on the southeast side, near downtown, and along older corridors have many homes from the 1950s through 1970s with insulation that has settled or degraded significantly. These are the homes where blown-in upgrades tend to pay back the fastest and where the comfort difference is most noticeable. We also serve homeowners in Owatonna and Winona who face the same climate challenges.
Minnesota also requires insulation contractors to be licensed through the Department of Labor and Industry — so when you hire Rochester Insulation, you are working with a contractor whose license you can verify before the first truck pulls up. Homeowners in Mankato and the surrounding region can expect the same licensed, verifiable work.
We will ask a few basic questions — home age, the areas you are concerned about, and whether you have noticed ice dams or high bills. We respond within 1 business day and schedule a free in-home estimate.
We go up into your attic, measure what is there, and check for air leaks, moisture, or pest activity that should be addressed first. You get a written quote before we leave — no surprise numbers later.
The crew runs a long flexible hose through your attic hatch and blows material in evenly. The machine stays outside. Most attic jobs take two to four hours and you can stay home the whole time.
We leave depth markers so you can verify coverage yourself. The crew cleans up any stray material around the hatch. Insulation is effective immediately — no curing time needed.
We respond within 1 business day. There is no obligation to proceed after your estimate. After you submit, someone from our office calls to schedule a free on-site visit so we can measure your attic and give you an accurate, written quote.

Rochester Insulation works across southeastern Minnesota and into Wisconsin, so we understand the range of home ages and conditions in this region. From older IBM-era ranch homes to newer southwest subdivisions, we have seen the variety.
We never quote over the phone because attic conditions vary too much. Every estimate includes an in-person attic measurement, a written breakdown of materials and labor, and a clear scope of work. The{' '}
