Kokomo Insulation brings insulation contractor services to Marion, IN, including spray foam, attic insulation, and crawl space work, and our licensed crew has completed jobs across Grant County with a one business day reply and written estimate before any work begins.

Marion homes built before 1960 often have rim joists and crawl space walls that are completely uninsulated - wide open to the cold air and ground moisture that defines a Grant County winter. Our spray foam insulation seals those gaps airtight and creates a moisture barrier in one step, which is exactly what older Marion homes need in the spots where batts and blown-in material cannot get a proper seal.
Most of Marion's older Craftsman bungalows and Foursquare homes have attic insulation that has either settled over decades or was never updated from what was installed when the house was built. Cold January nights in Grant County - where lows can drop below zero - demand an attic that holds heat, not one that was adequate in 1940.
Grant County clay soil holds water and pushes moisture into crawl spaces after every heavy rain or snowmelt. An uninsulated crawl space under a Marion home is a direct path for cold air and ground moisture to reach your floors - we seal and insulate that space so it stops working against you.
For Marion attics that already have some insulation but need topping off to reach modern performance levels, blown-in material adds depth without tearing anything out. It works around the irregular framing and stored items that are common in older Grant County homes without requiring demolition or drywall work.
The Mississinewa River and the clay soils throughout Grant County keep ground moisture levels high in and around Marion. A properly installed vapor barrier on a crawl space floor cuts off that moisture source before it damages floor joists, and it works alongside crawl space insulation to keep the space dry through every season.
Marion homes from the 1910s through 1940s were built with framing gaps, open stud bays, and old plumbing penetrations that let cold air move freely inside the wall and attic cavities. Air sealing closes those pathways before insulation goes in, which is what makes the difference between a home that stays warm and one that still has cold rooms after an insulation upgrade.
Marion is a city where most of the housing stock dates from before 1960, and a significant portion of those homes have been in the same family for decades. That longevity is a good thing, but it also means insulation upgrades have been deferred in a lot of houses. Homes built in the 1910s through 1940s in Grant County were constructed to whatever standard was common at the time - thin fiberglass batts in the attic if anything at all, no attention to air sealing, and crawl spaces left completely open to outside air and ground moisture. Marion winters are cold enough that the ground freezes to a frost depth of 30 inches or more in a hard year, and the repeated freeze-thaw cycles from late winter through spring put steady stress on foundations and masonry.
Grant County clay soil compounds the problem. Clay does not drain well, and in Marion's older neighborhoods the grading around many homes has settled over decades so water pools against foundations rather than running away from them. The Mississinewa River runs through the city and keeps the water table relatively high in low-lying areas. That combination - cold winters with deep frost, clay soil that holds water, and housing stock that was never built to manage either problem well - creates persistent insulation and moisture control demands that a contractor needs to understand before proposing a solution. Treating Marion homes the same way you would treat a newer suburban build misses the underlying conditions entirely.
Our crew confirms permit requirements with the City of Marion building office before starting applicable projects, and we are familiar with what the inspectors in Grant County look for on insulation work. Marion has a meaningful share of rental properties - roughly half of occupied housing units are renter-occupied - and we have worked on both owner-occupied homes and investment properties throughout the city. The Craftsman bungalows and Foursquares near downtown Marion have very different attic and crawl space conditions than the ranch homes on the east side, and our crew knows what each type of home is likely to need before we arrive.
Marion is the county seat of Grant County and sits along the Mississinewa River, which gives the city a natural western boundary through the older neighborhoods and park areas. Matter Park on the north side of the city is a familiar landmark, and Indiana Wesleyan University anchors the south side. The streets between those two landmarks contain most of the city's older residential neighborhoods. We access jobs off of Washington Street through the center of town, off of 38th Street on the north side, and through the older streets west of the courthouse.
Marion is within our regular service area along with neighboring communities. We also serve homeowners in Frankfort, IN to the northwest and can coordinate work across both areas on the same trip when schedules allow. Homeowners in Kokomo, IN to the west are also part of our coverage area.
Reach out by phone or the contact form and we reply within one business day. We will ask about your home's age, what areas you want addressed, and any comfort problems you have noticed - so we arrive already knowing what older Marion homes in your part of town typically look like.
A crew member walks your attic, crawl space, or walls, measures existing insulation depth, checks for moisture or pest damage, and identifies whether air sealing is needed before new material goes in. You get a written estimate that itemizes the work clearly - no obligation, no pressure, and no surprise numbers when the job is done.
The crew arrives with the equipment your job requires. Most attic and crawl space jobs in Marion finish in one to two days. You can stay home during blown-in or batt work; if spray foam is applied, plan to be out of the house for at least 24 hours while it cures.
We walk through the finished work with you, show you what was installed and where, and handle any permit inspection paperwork if required. Most Marion homeowners notice a change in room temperatures within the first heating or cooling cycle after the job wraps up.
We serve all of Marion and Grant County. Reply within one business day, written estimates before any work begins, no pressure.
(765) 776-9811Marion is the county seat of Grant County in north-central Indiana, with a population of around 27,000 people. The city grew as a manufacturing and industrial center through the early and mid-1900s, drawing workers who built homes in the neighborhoods radiating out from downtown and along the streets near the old factory corridors. The result is a city where a large share of the housing stock dates from the 1910s through 1940s - Craftsman bungalows and American Foursquares are the dominant styles in the older in-town neighborhoods, and they sit on modest city lots with detached garages and mature trees. The Mississinewa River runs through the city and is one of the most recognized natural features in the area, known for fishing and the annual Mississinewa 1812 reenactment.
As you move away from downtown toward the edges of the city, the housing transitions to postwar ranch homes from the 1950s and 1960s and, at the outer edges, to newer subdivisions with larger lots. Indiana Wesleyan University on the south side is one of the city's largest employers and institutions, and the neighborhoods around it include both older homes and some of the more recently built residential areas in Marion. We serve all of Marion and regularly work in the surrounding Grant County communities. If you are near Frankfort or Kokomo, you are within our regular service area and can expect the same crew, timeline, and pricing approach we bring to Marion.
