Before signing for crawl-space insulation in Indianapolis, identify which program could cover the actual work and whether it must approve the project first. Indiana Energy Saver lists crawl-space-related measures, but that does not make every encapsulation package eligible. AES Indiana’s advertised insulation rebate concerns attics. Citizens’ Indianapolis rebate page concerns appliance conversions. These are different routes with different paperwork.
Reviewed October 15, 2026. This guide focuses on existing Indianapolis and Marion County homes. Program rules, funding and property eligibility can change.
Start with the bills for the property
Write down the electricity provider, heating fuel and gas provider, if any. Use the service address and account information on the bills rather than a contractor’s “Indianapolis area” label. A company serving your neighborhood does not establish your utility-program eligibility.
- AES Indiana: Its home-improvement rebate page lists attic insulation and requires electric heat for that measure. It also requires an AES Quality Contractor Network member. Do not apply an attic allowance to crawl-space floor or foundation-wall insulation. Ask AES about your exact proposed measure before including any discount in the budget.
- Citizens Energy Group: The utility separates Indianapolis and Westfield rebate routes. The Indianapolis page currently describes natural-gas appliance conversions; it does not list a crawl-space insulation rebate. A Citizens bill alone is not evidence that an insulation project qualifies.
- Another provider: Check that provider’s current residential program. Do not transfer AES requirements or a neighboring utility’s offer to your address.
What Indiana Energy Saver actually supports
The state’s Indiana Energy Saver Program overview directs applicants to one application for HOMES and HEAR. The benefit is an upfront discount on eligible products and installation through the program.
The current eligible-measure list includes crawl-space encapsulation air sealing, floor batt insulation and foundation insulation. That supports asking about a crawl-space project. It does not approve a specific product, whole package or contractor for your house.
For HOMES, eligibility includes a whole-home project achieving at least 20% modeled energy savings. Discount limits depend on household income relative to county area median income and modeled savings. For a Marion County home, have program staff establish the applicable household category. Insulating one crawl space does not itself prove that the savings threshold will be met.
Get into the program before committing to installation
The official pre-screening page warns that projects initiated outside the program process after May 14, 2025, are not eligible for retroactive HOMES rebates. For a new project, do not assume you can hire someone now and submit the receipt later.
The current contractor manual describes a program-developed work order, an agreement with the regional general contractor, any required customer contribution, and a Notice to Proceed. Ask your program contact to confirm which stage you have reached before authorizing installation or changing the scope.
You can gather inspection findings and preliminary estimates while investigating eligibility. Label them as preliminary. Ask when the proposed price expires and whether changes require a new estimate. If urgent water or safety work cannot wait, discuss that separately with the appropriate professional and the program; do not assume it will be reimbursed.
Keep the eligibility file separate from the construction scope
The household application guidance explains ownership, income and utility documentation. Have the latest bill for each utility ready; the program may request up to 13 months of usage. It asks applicants to redact Social Security numbers where possible. Submit sensitive records through the official application process, rather than distributing them with requests for contractor quotes.
For the proposed work, request these items in writing:
- Exact measures: Identify each insulated or air-sealed surface, quantities, materials and installed specifications. Avoid a single unexplained “encapsulation” line.
- Separate costs: Show the full scope, confirmed program discount, customer contribution and privately funded extras. Identify which amounts remain provisional.
- Prerequisites: List water correction, damaged-material removal, access preparation and any specialist evaluations. Ask which are included in the approved work order.
- Responsibilities: Name the coordinator, installer, paperwork contact and person who obtains any necessary local approvals.
- Changes and closeout: Explain who approves substitutions or hidden-condition work and which photographs, product records and completion documents you receive.
These are comparison prompts. The program and the professionals evaluating the house must determine the eligible scope and installation requirements. Keep separate concerns visible, including the coordination described in our Indianapolis crawl-space radon-planning guide.
Two existing profiles for scope discussions
Homeward Insulation describes Indianapolis crawl-space insulation on its company website. Hoosier Spray Foam, based in Westfield, lists crawl-space encapsulation and Indianapolis among its service locations on its official about page. Ask each about the exact address and work you need.
These are unranked directory choices, not endorsements or verified program participants. IESP’s FAQ says only approved network contractors may perform program-funded work. You may express a contractor preference, but assignment is not guaranteed. Verify participation and assignment with the program before treating an outside quote as the program price.
For additional starting points, browse the Indiana contractor directory and confirm the exact address, service and program status directly.
Questions to resolve before signing
Can a duplex use the same application assumptions?
No. The current IESP FAQ says it is not accepting duplex, triplex or quadplex applications. Confirm property-type eligibility directly rather than relying on a general reference to multifamily rebates.
What if someone offers to enroll me at my door?
Indiana’s energy office says IESP contractors do not solicit door-to-door. Start from the official state program link and verify any claimed assignment before sharing personal records or committing to work. Its FAQ also says IESP will not ask for payment directly to a contractor. Verify any requested customer contribution with the program.
