Insulation and Air Sealing in Davenport and the Quad Cities

Iowa Illinois Insulation & Air Sealing provides professional residential insulation, air sealing, blower-door testing, infrared imaging, energy audits, dense-pack wall insulation, insulation removal, insulation capping and targeted two-part polyurethane foam applications throughout Davenport, Bettendorf and the Quad Cities. Backed by a family-owned local company serving Iowa and Illinois since 1976, we help homeowners identify where energy is being lost, seal accessible air leaks and install insulation that improves comfort and strengthens the home’s thermal envelope.

Our approach is different from simply adding insulation and hoping the problem improves. We evaluate how air, heat and moisture move through the home, inspect the existing insulation and identify areas where outside air may be entering or conditioned air may be escaping. Based on what we find, we develop a practical plan designed around the home’s construction, condition and the homeowner’s goals.

Whether you are dealing with cold rooms, drafts, uneven temperatures, low attic insulation, high utility use or an older home with empty wall cavities, Iowa Illinois Insulation & Air Sealing can help determine the right next step. Click here to schedule an inspection.

What Do We Do?

We provide complete residential insulation and air-sealing services for homeowners throughout Davenport, Bettendorf, Moline, Rock Island and surrounding communities in eastern Iowa and western Illinois.

Our services include blown-in cellulose attic insulation, dense-pack wall insulation, insulation removal, insulation capping, professional air sealing, blower-door testing, infrared imaging, residential energy audits and targeted applications of two-part polyurethane foam.

We do not install full spray-foam insulation systems. Two-part polyurethane foam is used only for approved localized air-sealing applications where it is appropriate for the building assembly and project scope.

Our goal is to improve the relationship between the home’s air barrier and thermal barrier. Insulation helps slow heat transfer, while air sealing reduces uncontrolled air movement through gaps, penetrations and framing openings. In many homes, both issues need to be addressed to improve comfort effectively.

Blown-In Attic Insulation

Attics are one of the most important areas to evaluate when a home is difficult to heat or cool. Existing insulation may be too shallow, uneven, disturbed, damaged or missing in certain areas. Openings around plumbing, wiring, framing and mechanical penetrations may also allow conditioned air to escape into the attic.

We install blown-in cellulose insulation in suitable residential attics. Before adding insulation, accessible air-leakage areas should be evaluated so they can be addressed before they are covered. We also consider attic ventilation, baffles, access points, existing insulation condition and the overall roof and attic assembly.

When appropriate, cellulose may be installed over suitable existing insulation to improve depth and coverage. In other situations, damaged or contaminated material may need to be removed before additional work begins.

Dense-Pack Wall Insulation

Many older homes in Davenport, Rock Island, Moline and other established Quad Cities neighborhoods were built before modern insulation practices became standard. Some exterior wall cavities may be empty or only partially insulated.

Dense-pack cellulose may be installed into suitable wall cavities from the exterior when the home’s construction allows. Small access points are created so each cavity can be filled at the appropriate density. The access points are then closed as part of the approved project scope.

Dense-pack wall insulation can help reduce heat transfer, improve comfort and limit air movement within suitable wall cavities. Every home must be evaluated first because siding type, wall construction, moisture conditions and previous remodeling can affect whether this method is appropriate.

Professional Air Sealing

Insulation alone does not stop air from moving through openings in the building. Air can enter through the basement, crawlspace, rim joists, wall penetrations and exterior gaps, then move upward through the home and escape through attic bypasses.

Professional air sealing may include accessible plumbing penetrations, electrical penetrations, top plates, attic chases, framing gaps, attic access points, rim and band joists, basement penetrations and other areas where uncontrolled air movement is occurring.

The exact air-sealing plan depends on the home’s construction and the areas that can be accessed safely. Our team evaluates the home and explains which leakage areas should be prioritized.

Insulation Removal and Insulation Capping

Old insulation does not always need to be removed. If the existing material is dry, stable and in suitable condition, additional insulation may be installed over it to improve total coverage. This process is commonly referred to as capping the existing insulation.

Removal may be recommended when insulation has been damaged by water, heavily contaminated by pests or wildlife, compressed, disturbed, filled with debris or affected by renovation work. Removing the old material can also provide access for more complete air sealing before new insulation is installed.

Our team evaluates the condition of the existing insulation and recommends removal or capping based on what is found.

Residential Energy Audits

A residential energy audit helps identify where the home may be losing conditioned air or experiencing weaknesses in the building envelope. The evaluation may include a review of insulation levels, accessible air-leakage areas, attic conditions, basement or rim-joist areas and other factors affecting comfort and efficiency.

Blower-door testing and infrared imaging may be used when appropriate to gather additional information. The result is a clearer understanding of the home and a more informed plan for insulation and air-sealing improvements.

Can We Identify the Problem?

Yes. One of the strongest advantages of working with Iowa Illinois Insulation & Air Sealing is our ability to investigate the home before recommending the work.

Drafts, cold rooms and high utility use do not always originate where the homeowner feels the problem. Air may enter at one level of the home and escape at another. A cold room may be affected by an empty wall cavity, attic leakage, basement leakage or a combination of conditions.

Our diagnostic process begins with a conversation about what you are experiencing. We then evaluate accessible areas of the home, inspect the existing insulation and look for visible leakage pathways or construction concerns.

Blower-Door Testing

A blower door is a diagnostic tool used to measure how much air leaks through the building envelope. A temporary frame and calibrated fan are installed in an exterior doorway. The fan creates a controlled pressure difference that allows air leakage to be measured and investigated.

Blower-door testing can help identify whether the home is unusually leaky and can make hidden leakage areas easier to detect. The test is especially useful when the homeowner experiences drafts, uneven temperatures or comfort problems that are difficult to trace visually.

Blower-door testing may also be used to compare conditions before and after air-sealing work when post-work verification is included in the project scope.

Infrared Imaging

Infrared imaging can help reveal temperature differences across walls, ceilings and other building surfaces under suitable conditions. These temperature patterns may indicate missing insulation, uneven coverage, thermal bridging or air movement.

Infrared images must be interpreted in context. Weather conditions, indoor-to-outdoor temperature differences, sunlight, moisture and building materials can affect what appears on the camera. We use infrared imaging as one part of a broader evaluation rather than treating every temperature difference as proof of a specific problem.

Visual Building-Envelope Inspection

Not every issue requires advanced equipment. A detailed visual inspection can reveal low insulation levels, displaced material, attic bypasses, open wall cavities, gaps around penetrations, damaged insulation, pest activity and other conditions that may contribute to comfort or efficiency problems.

Our experience with pest control, wildlife exclusion, weatherization and building repairs helps us recognize openings that may allow both outside air and animals to enter the home.

Is Your Home Showing Symptoms?

Many homeowners are unsure whether their discomfort is caused by insulation, air leakage, HVAC performance, windows or another issue. An evaluation is the best way to determine the cause, but several common symptoms may indicate that the home could benefit from insulation or air-sealing improvements.

Drafty Rooms

Noticeable drafts near walls, floors, outlets, windows, attic access points or exterior penetrations may indicate uncontrolled air leakage. The draft may come directly through the area where it is felt, or it may be caused by air moving through connected cavities within the home.

Uneven Temperatures

Rooms that are consistently hotter or colder than the rest of the house may have inadequate insulation, missing wall insulation, excessive air leakage or other building-envelope issues. Upper floors that overheat in summer or rooms over garages that remain cold in winter are common concerns.

Low or Uneven Attic Insulation

If attic insulation is shallow, compressed, disturbed or missing in sections, the home may be losing more heat through the ceiling than necessary. Existing insulation may also hide unsealed penetrations that should be addressed before more material is added.

Heating and Cooling Equipment Running Frequently

Frequent HVAC operation can be caused by many factors, including equipment condition, thermostat settings, duct issues and building-envelope leakage. Insulation and air sealing may help reduce the load on the system when heat loss or air leakage is part of the problem.

Cold Floors

Cold floors may indicate air leakage or insufficient insulation above a basement, crawlspace, garage or other unconditioned area. Rim joists and band joists are also common leakage locations in many homes.

Ice Dams or Attic Frost

Ice dams and attic frost can be associated with heat and moisture moving from the living space into the attic. Roof design, ventilation, weather conditions and insulation coverage can also contribute. These conditions should be evaluated carefully rather than treated with insulation alone.

Older Exterior Walls

Older homes may have empty wall cavities, inconsistent insulation or previous remodeling that interrupted the thermal boundary. Dense-pack cellulose may be an option for certain homes after the wall construction and exterior materials are evaluated.

Pest or Wildlife Entry

Openings that allow air into a home can sometimes also provide entry points for insects, rodents or wildlife. Our background in pest control and exclusion allows us to recognize certain conditions that may affect both energy performance and animal entry.

Why Should You Trust Iowa Illinois Insulation & Air Sealing?

Choosing an insulation contractor requires more than comparing prices. The work can affect comfort, moisture movement, ventilation and the performance of the entire building envelope. Homeowners should understand what is being recommended, why it is needed and how the work will be completed.
