Indianapolis sits flat across the central Indiana till plain, and that means real heat and real cold. Your attic bakes at 130 to 150 degrees in July and drops below zero in January. Your crawl space sweats in spring and frosts in winter. The balloon-framed doubles and bungalows inside the 465 loop, the post-war ranches beyond it, and the newer subdivisions spreading north and west all share the same problem: empty wall cavities, vented attics that leak conditioned air, and rim joists that let the cold in.

Indianapolis Spray Foam Insulation has been sealing and insulating homes and commercial buildings across Indianapolis and the surrounding area since 2012. We know the neighborhoods, the building stock, and the moisture and temperature swings that make this city hard on insulation. When your heating or cooling bill climbs, or a room won't reach temperature, or you see condensation in the attic or crawl space, we come out to your property, look at what is actually there, and tell you what will work and what it costs.

Spray Foam Insulation in Indianapolis (46204)

The homes in Indianapolis were built in waves, and each one has a different insulation problem. The 1870s to 1920s Victorians and worker cottages in Irvington, Fountain Square, Old Northside, Herron-Morton Place and Fletcher Place have balloon frames and empty wall cavities under clapboard or aluminum siding. The 1910s to 1930s foursquares and bungalows in Meridian-Kessler, Broad Ripple and Butler-Tarkington have finished half-story attics with knee walls that collect ice dams every winter. The 1950s and 1960s ranches in Lawrence, Speedway, Beech Grove, Southport and the township belts sit on vented crawl spaces with flattened original insulation and cold floors. The 1990s and newer two-stories in the subdivision belts of Carmel, Fishers, Westfield, Noblesville, Zionsville, Avon and Brownsburg have bonus rooms above three-car garages and vaulted great rooms that the original ductwork was never sized to reach. Beyond the suburbs, the post-frame barns and barndominiums in Boone, Hendricks and Johnson County need sealed, insulated cavities to stop the seasonal sweat and frost.

Vapor drive in central Indiana flips with the seasons. Winter brings sub-zero nights and frozen pipes. Summer brings 90-degree heat and humidity. Every assembly has to handle both. We have been serving Indianapolis and the surrounding area since 2012, and we know what works in this climate and what does not.

How a Job Works in Indianapolis

You call us at (463) 285-8584 or request an estimate online. We schedule a time to walk through your property, look at the attic, crawl space, walls or rim joists that need work, and understand what is already there. We take measurements, ask about your comfort complaints, and look for moisture, condensation or damp insulation that has to be fixed before any foam goes in. We leave you with a written estimate that names the R-value, the thickness we will spray, the area to be covered, and the price. No surprises.

On the day of the work, our crew arrives with the spray rig and the equipment to control the application. We set up mechanical ventilation if we are working indoors, and we maintain the manufacturer ratio and drum temperature on every pass. We spray to the thickness and R-value in the estimate, then we leave the space to cure. Most jobs are complete in a day. For attics and crawl spaces in occupied homes, we recommend a re-entry window of twenty-four to forty-eight hours before the space is used again, and we tell you that window up front.

When the cure is complete, we walk the property with you, show you the work, and leave the site clean. If we had to remove old insulation first, the debris is hauled away. You get a copy of the estimate and the work performed.

Attic spray foam insulation in Indianapolis typically runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, depending on the thickness and R-value you need and the access your attic allows. A typical attic job in a ranch or two-story home runs $2,500 to $6,000. Wall and injection foam for closed-in cavities starts at $2 per square foot. Crawl space jobs typically start at $2,500 and depend on the square footage and depth. Rim and band joist sealing starts at $650. If old insulation has to come out first, removal runs from $950 depending on what is there and how much of it. The key cost factors are the area to cover, the thickness and R-value specified, whether you choose open cell or closed cell, what has to be removed first, and how tight the access is. We measure everything on site and give you a firm price in the written estimate. Call us at (463) 285-8584 for a free estimate, or request one online and we will contact you within one business day.

I live in a 1920s bungalow in Fountain Square with a finished attic. Every winter the roof leaks, and I can see water stains on the ceiling. Is spray foam the answer?

Not yet. A roof leak has to be fixed before any insulation goes in. What we can do is seal the attic air leaks around the rim, the knee walls, the ductwork and the penetrations once the roof is dry, and then spray closed cell foam to the underside of the roof deck to stop the condensation and ice dam cycle that makes the leak worse. Call us at (463) 285-8584 and we will walk through it with you.

The crawl space under my 1950s ranch in Southport is damp in the spring, and the floor is always cold. The insulation down there is matted and wet. Do I need to remove it before you spray?

Yes. Wet or damp insulation has to come out before any foam goes in. We will remove it, haul it away, let the crawl space dry, and then spray closed cell foam to the rim, band joist and underside of the floor joists. That stops the cold air from underneath and the moisture from below. If the crawl space has standing water or active seepage, we will walk away and refer you to someone who handles moisture control. We fix the moisture first or we do not spray.

How much does it cost to add spray foam insulation to the walls of my older home in Irvington?

Wall injection foam for closed cavities starts at $2 per square foot. The cost depends on how many walls you want done, how high they are, and what access we have to drill and inject. A typical two-story home with injection foam on the exterior runs $4,000 to $8,000. We come out and measure, then give you a written estimate with the square footage and the price. Call (463) 285-8584 for a free estimate.

Who decides what R-value and thickness I need for my attic in Indianapolis, and who inspects the work?

The energy code and building code in force at your address set the R-value requirement. That varies by ZIP code and by when your home was built. The building official in Indianapolis or your township has the final say on what applies to your property. We will tell you what the code calls for at your address, and we will spray to that thickness and R-value. You can verify the requirement by contacting the City of Indianapolis website at https://www.indy.gov or your local building department. The inspector will want to see the thickness, the coverage, and the R-value nameplate from the foam system.

I am having spray foam sprayed in my attic next week, but I live in the house. How bad is the smell, and how long before I can go back up there?

Spray foam has a strong chemical smell while it is being applied and curing. We set up mechanical ventilation during the spray and cure to pull the odor out of the house. We recommend that you stay out of the attic and keep bedroom doors closed for twenty-four to forty-eight hours after the spray is complete. Most homeowners report that the smell is gone within a few days of cure. We will tell you the exact re-entry window when we do the job.

Are you fully insured for spray foam insulation work at my Indianapolis property?

Yes. We carry general liability and workers' compensation insurance. You can ask us for proof of coverage before the work starts, and we will provide it. Our team is fully insured on every job.

It is July and my air conditioning bill is out of control. Is this the right time to spray foam my attic, or should I wait until fall?

July is actually a good time to see the problem. Your attic is baking, and that heat is soaking into your home and driving up the cooling bill. Spray foam in the attic stops that heat transfer and can bring relief within days. We can schedule the work in the early morning or late afternoon to minimize the time the attic is disturbed, and the crew will set up ventilation to manage the heat. Fall and winter are also good times, but if you are uncomfortable now, we can help. Call (463) 285-8584 and we will find a time that works.
