Heat rises - and in older Dubuque homes, it escapes straight through the attic. Proper attic insulation keeps that warmth where it belongs: inside your home.

Thin or uneven attic coverage? Blown-in insulation fills every corner evenly and can bring an under-insulated attic up to current standards in a single day.

Cold rooms, ice dams, high utility bills - these are signs your whole home needs a thermal upgrade. We assess every area and recommend the right approach.

Old insulation damaged by moisture or pests? Putting new material on top of bad material traps the problem in. We remove it safely before starting fresh.

A cold, damp crawl space pulls heat out of your floors all winter. Insulating it keeps the rooms above warmer and stops moisture from sneaking up.

If exterior walls feel cold to the touch in January, there is likely little or nothing insulating them. We add coverage without requiring a full gut renovation.

Insulation slows heat loss - air sealing stops drafts completely. Together they make the biggest difference in home comfort and energy bills.

Uninsulated basement walls are one of the biggest sources of heat loss in older Dubuque homes. Insulating them makes the floors above noticeably warmer.

Need insulation and a moisture barrier in one step? Closed-cell foam is dense, rigid, and the right choice for crawl spaces, basements, and rim joists.

Open-cell spray foam is ideal for interior walls and attics where sound control matters and moisture exposure is low. Soft, flexible, and highly effective.

Air sealing your attic before adding insulation is the step most contractors skip - and the one that makes the biggest difference in your energy bills.
Learn More
Ground moisture rises through crawl spaces year-round. A vapor barrier stops that cycle and protects your floors, joists, and insulation from damage.
Learn More
Moisture in crawl spaces and basements quietly causes rot, mold, and structural damage. A vapor barrier cuts off the moisture at the source.
Learn More
Older homes were built without modern insulation in mind. Retrofit insulation adds coverage to existing walls and spaces without tearing everything apart.

Commercial buildings have different insulation requirements than homes. We handle spray foam, blown-in, and vapor barrier installations for commercial properties.

"We had them do the attic in November, right before the cold set in. First heating bill after the work was noticeably lower - not a little, but actually noticeable. The crew was in and out in one day and cleaned up after themselves."
Mark T., Dubuque, IA - Attic insulation
"The crawl space under our 1930s house was completely uninsulated. They came out, assessed everything, and had it done within the week. The floors above it are warmer now and the musty smell that was drifting up is gone."
Susan R., Cedar Rapids, IA - Crawl space insulation
"I was skeptical that spray foam would make a real difference in our drafty old home. It did. Two rooms that were always cold are now the same temperature as the rest of the house. Wish we had done it years ago."

Most heat escapes through the attic - not windows or doors. If your attic floor has thin or damaged insulation, warm air rises straight out of your living space. In Dubuque's climate zone, the DOE recommends significantly higher insulation levels than most older homes currently have.
Ice dams form when heat escapes through the attic and melts snow unevenly on the roof. The meltwater refreezes at the cold eaves and can force water under shingles. Proper attic insulation and ventilation is the long-term fix - not roof raking or heat cables.
Yes. Blown-in insulation can be added to existing wall cavities through small holes drilled from the exterior, then patched. Spray foam handles irregular crawl spaces and rim joists without major renovation. Older homes are often the best candidates for retrofit insulation. The{' '}U.S. Department of Energy provides detailed guidance on insulation options for existing homes.
Yes - they behave differently and suit different areas. Open-cell is softer and cheaper, good for interior walls and attics where moisture is not a concern. Closed-cell is denser and creates a vapor barrier, making it the right choice for crawl spaces, basements, and any area exposed to moisture.
Homeowners can claim a federal tax credit worth up to 30 percent of the cost of qualifying insulation materials, with a cap of $1,200 per year under the Inflation Reduction Act. Keep your receipt and product documentation. Your contractor should be able to tell you whether the materials they use qualify.
If your crawl space floor is bare dirt or concrete without a plastic sheet covering it, ground moisture is rising into your home year-round. A vapor barrier stops that. Insulation on the walls or underside of the floor above adds thermal resistance. Most crawl spaces in older Dubuque homes need both.

Building Performance Institute If your insulation is over 30 years old, has been wet, or shows signs of pest activity, adding more on top traps the problem in. A contractor should inspect and remove damaged material first. The provides standards for assessing existing insulation.
Insulation slows heat moving through walls and ceilings. It does not stop air from moving through gaps around pipes, wires, and fixtures. If air sealing is skipped, warm air keeps escaping through those gaps even with new insulation on top. The improvement will be smaller than expected.
MidAmerican Energy and Alliant Energy both offer rebates for qualifying insulation upgrades. A participating contractor handles the paperwork. You do not need to apply separately. Ask your contractor whether they participate in the utility rebate program before you approve any quote.

Dubuque is one of the oldest cities in Iowa, built on a series of dramatic bluffs rising above the Mississippi River. The city is home to roughly 60,000 residents, with a housing stock that skews older than most Iowa communities - a large share of homes date to the late 1800s and early 1900s. Landmarks like the Fenelon Place Elevator and the historic Cable Car Square neighborhood reflect the city's deep roots in 19th-century architecture and riverfront commerce.
The city markets itself as the Masterpiece on the Mississippi, and its Victorian and Italianate homes are a major part of that identity. Those same historic homes - built long before modern insulation standards existed - are also among the hardest to heat efficiently. Many were constructed with balloon-frame walls, minimal attic coverage, and no crawl space insulation whatsoever. Dubuque winters regularly push temperatures below zero, and homes that have never been insulated properly pay a steep energy penalty every heating season.
Dubuque Insulation works throughout Dubuque, from the bluff neighborhoods near downtown to newer subdivisions on the west side. We know the difference between a pre-1940 home with plaster walls and knob-and-tube wiring and a newer build that just needs an attic top-up. Major employers like John Deere Financial, IBM, and Mercy Medical Center keep many residents rooted here for decades - and long-term homeowners invest in improvements that make their homes genuinely comfortable, not just livable.
