Old, wet, or pest-damaged insulation can no longer do its job. We remove compromised material safely before installing fresh insulation that performs the way it should.

Cold floors in January? Your crawl space is the most likely cause. Insulating it stops cold air from pressing up through your floor and dramatically improves first-floor comfort.

Drafty walls make rooms uncomfortable regardless of how hard your furnace works. We insulate existing walls without full demolition using targeted blown-in techniques.

Insulation slows heat transfer, but air leaks defeat it entirely. Air sealing closes the gaps around lights, pipes, and hatches where conditioned air escapes fastest.
Learn MoreReach out by phone or online and we schedule a free in-home visit. You tell us what you are noticing, whether that is high heating bills, cold floors, or ice dams. We come to you with no commitment required. Most Rochester homeowners get an estimate appointment within a few days.
We walk your attic, crawl space, and other areas, measure what is already there, and look for air leaks. After the visit, you receive a written quote that explains exactly what will be done and what it costs. We respond to estimate requests within 1 business day. No surprises, no pressure to sign on the spot.
On the scheduled day, our crew arrives, protects your home, and completes the work, usually in a single day. Before we leave, we walk you through the finished job and answer any questions. You get documentation of the work for your records, your rebate claim, or a future home sale.
We hold the residential contractor license required by the Minnesota Department of Labor and Industry. Every job carries full liability insurance and workers' compensation coverage, so you are protected from the first day on site to the last.
We measure your space in person before quoting. You get a written price that covers materials, labor, and any required permit fees. There is no charge for the estimate, and you are never pressured to sign anything on the day of the visit.
We live and work here. We know the difference between a 1960s IBM-era ranch on the southeast side and a newer build out in the southwest subdivisions. That local knowledge changes how we size and approach every job.
Our workmanship is backed in writing. Most insulation materials we install also carry a manufacturer's product warranty. Before we leave, you get a copy of both so you have documentation for your records, your utility rebate, or the next time you sell.

Our heating bills dropped noticeably the first winter after they insulated the attic and sealed the rim joists. The crew finished in a single day and cleaned up completely before leaving. I wish we had done it five years earlier.
We had ice dams every year for the past decade. After the attic air sealing and blown-in insulation job, we went through the whole winter without a single one. The estimator was thorough and explained exactly what was causing the problem.
The crawl space under our 1968 ranch was completely uninsulated. After the spray foam and vapor barrier work, the first floor is a completely different house. Cold floors in January are gone. The quote matched the final invoice exactly.

Heat rises and escapes through the attic faster than anywhere else in the house. If your bill climbs every fall, the attic is the first place to check. The U.S. Department of Energy estimates that air sealing and insulation together can reduce heating and cooling costs by up to 15 percent for a typical home.
Open-cell foam is lighter and works well for interior walls and attic decks where sound dampening matters. Closed-cell foam is denser and also blocks moisture, which makes it the better choice for rim joists and crawl spaces in Minnesota. Your contractor should recommend the right type based on your specific location.
Insulation slows heat transfer, but air leaks let heat escape entirely. Sealing gaps around recessed lights, plumbing penetrations, and attic hatches is what closes the path for air movement. According to the{' '}<a href='https://www.energy.gov/energysaver/air-sealing-your-home' target='_blank' rel='noopener noreferrer' className='text-accent underline underline-offset-2'>U.S. Department of Energy</a>, a properly air-sealed and insulated home uses meaningfully less energy than one that only has insulation added.
Minnesota's freeze-thaw cycles push moisture up through exposed soil and into your home's structure. An uninsulated crawl space allows cold air and humidity to press up through your floors, raising humidity levels that can cause wood rot and mold. A vapor barrier combined with insulation addresses both problems.
If you can see the tops of the wooden joists in your attic, the insulation is not deep enough for Rochester's climate. Homes built before 1990 in Rochester were insulated to standards that fall well short of what the Department of Energy recommends for this climate zone. A free contractor inspection can confirm in 30 minutes.
Ice dams form when heat escapes through the attic and melts snow on the roof, which refreezes at the cold eaves. They are not a roofing problem, they are an attic insulation and air-sealing problem. Addressing both in the attic removes the source of heat that drives ice dam formation in the first place.

We hold the residential contractor license required by the Minnesota Department of Labor and Industry, covering all insulation, air-sealing, and vapor barrier work we perform. Our team has completed projects across all 16 service types we offer, in homes ranging from early-1900s downtown buildings to new southwest-side construction. We keep the operation local and the work accountable.
R-value measures how well insulation resists heat flow. Minnesota's cold climate requires higher R-values than most states, especially in attics. A contractor will measure what you have and tell you how far you are from the recommended level.
Fall is the most popular time because homeowners want to be ready before winter. Spring also works well, and contractors are often less busy. The work itself can be done year-round, though demand picks up sharply from October through December.
Yes. Xcel Energy serves much of Rochester and offers rebates for qualifying insulation upgrades. A federal tax credit for energy-efficient home improvements is also available for qualifying insulation materials. Ask your contractor to confirm what applies before the work begins.
Dense insulation in interior walls and between floors noticeably reduces sound transmission. If you have a noisy street, a home office, or rooms you share with family members, asking about interior-wall options during the estimate visit is worth your time.
The North American Insulation Manufacturers Association maintains homeowner resources on insulation standards and contractor selection. If you are ready to find out where your home stands, call us at (507) 738-1270 for a free on-site assessment.
Rochester, MN is the third-largest city in Minnesota, with roughly 121,000 residents and a local economy anchored by Mayo Clinic, the world-famous medical center that draws professionals and patients from across the country and internationally. The city has grown steadily for decades, and that growth has produced a housing stock that spans more than a century of construction styles and energy standards.
Rochester is divided into recognizable neighborhoods. The historic Pill Hill neighborhood near the medical campus features older Victorian and Craftsman homes from the early 1900s. The southeast side of the city, shaped largely by the IBM campus that arrived in the 1950s, is full of ranch-style and split-level homes from that era. The southwest neighborhoods, which have grown rapidly since the 1990s, have newer construction on smaller lots. The Destination Medical Center initiative continues to reshape the downtown core, bringing more residents and more homes that need proper maintenance.
Rochester's climate is genuinely demanding. The city averages about 46 inches of snow per year and regularly sees January temperatures drop below zero. The combination of deep cold and freeze-thaw cycles in the shoulder months puts constant pressure on every part of a home's building envelope, from rim joists to attic decks. Homes in the older IBM-era neighborhoods on the southeast side, many built between 1955 and 1975, were constructed well before current insulation standards and frequently need meaningful upgrades to perform through a modern Rochester winter. Near landmarks like Soldier's Field Veterans Memorial and throughout the downtown neighborhoods, older homes see the most benefit from air sealing and insulation improvements.
Whether your home is a 1910 Craftsman near downtown, a 1965 ranch on the southeast side, or a newer subdivision build on the southwest edge of the city, our team knows what Rochester homes need and what Rochester winters demand. Call us to schedule a free on-site estimate.
