Insulation Rebates in the Greater Baltimore Area: A 2026 Homeowner’s Guide

If you own a home in Baltimore or the surrounding counties, upgrading your insulation is one of the most cost-effective ways to fight our humid Mid-Atlantic summers, cold winters, and stubborn energy bills, and in 2026 the right rebates can cover a real share of the cost. Maryland homeowners are in an unusually strong position, too. The federal insulation tax credit ended on December 31, 2025, but Maryland runs one of the most generous utility efficiency programs in the country, EmPOWER Maryland, so today the savings come mainly from your utility: BGE across most of the metro, and Pepco in the Montgomery County communities we serve.

This guide breaks down every insulation, air sealing, and ventilation rebate available across the greater Baltimore area in 2026, what each program requires, and the mistakes that quietly cost homeowners their rebate. It is written by the team at Koala Insulation of the Greater Baltimore Area, your locally owned insulation company based here in Baltimore and serving homeowners throughout the region. Because the best programs now require a professional contractor, a home energy audit, and verified results, we also show you how we help you plan a rebate-ready project from the first assessment through the final documented invoice.

Quick Answer: What Insulation Rebates Can I Get in the Baltimore Area in 2026?

For most of the metro, your electric and gas efficiency programs run through BGE under EmPOWER Maryland. BGE’s Home Performance with ENERGY STAR program pays rebates on air sealing and insulation based on your home’s modeled energy savings, up to $10,000 or 75% of the project cost, after a home energy audit with a participating contractor. In the northern Montgomery County communities we cover, the same kind of program runs through Pepco. Income-eligible households can get insulation and air sealing at no cost through the state’s Weatherization Assistance Program. Maryland’s federally funded Home Energy Rebates are coming but are not open yet, and the federal 25C tax credit ended December 31, 2025. What you actually qualify for depends on your address, your utility, and your household income.

The single most important rule: verify and reserve your rebate before work begins. The utility programs require an audit and a participating contractor first, and they will not approve a project after the fact. Confirming this for your specific address is the first thing our team does.

Start With the Trifecta: Insulation, Air Sealing & Ventilation

Before you chase any rebate, it helps to understand what actually makes a home efficient. Real comfort and savings come from three things working together, what the industry calls the trifecta. Chasing one without the others is where most homeowners, and a lot of quick, cut-rate jobs, go wrong. It is also, as you will see, exactly how Maryland’s utility program is designed.

1. Insulation, slow the heat transfer

Insulation is the resistance layer (its R-value) that slows heat from moving into your home in July and out of it in January. Most Baltimore-area attics are simply under-insulated for our climate. Adding blown-in attic insulation or spray foam to the right depth is often the single highest-impact upgrade, and the one most utility rebates are built around.

2. Air sealing, stop the uncontrolled leaks

Insulation slows heat, but it does not stop air. Gaps around attic penetrations, top plates, recessed lights, plumbing chases, and rim joists let conditioned air pour out and humid outside air pour in, which is why a home can be “fully insulated” and still feel drafty. Air sealing plugs those leaks, and it is so central to real performance that BGE requires it before insulation on every Home Performance job. In our humid climate, sealing also keeps moisture out, protecting against the mold and allergen problems that plague leaky homes.

3. Ventilation, let the home breathe

The third leg is the one people forget: ventilation. Once you insulate and air-seal, the home needs balanced intake and exhaust so summer heat and winter moisture can escape instead of baking your shingles or condensing into your insulation. This matters so much that BGE’s program requires ventilation to indoor air quality standards as part of a qualifying project. Proper attic ventilation, including a solar attic fan where it makes sense, protects your investment and keeps the whole assembly healthy.

Why the trifecta matters for rebates: the strongest programs reward the whole building envelope, not a single product. Maryland’s Home Performance with ENERGY STAR program is built around all three, air sealing first, then insulation, with ventilation to protect air quality. Addressing the trifecta together is how you maximize both comfort and incentive dollars, and Koala handles all three under one roof.

Why Insulation Rebates Matter for Greater Baltimore Homes

The Mid-Atlantic is tough on a building envelope. Summers are hot and humid for months at a stretch, winters bring real cold, and spring and fall swing between the two. That constant temperature and moisture load wears insulation down and makes air leaks worse over time. Poor insulation shows up as uneven room temperatures, high summer and winter bills, and, because so many local homes have older attics, basements, and crawl spaces, a real risk of moisture and mold breaking down your insulation.

Rebates matter because they lower the upfront cost of fixing all of that. Heating and cooling can account for roughly half of a typical home’s energy use, so a properly insulated, sealed, and ventilated home is more comfortable, healthier, and cheaper to run for decades. A rebate should not be the only reason to act, but with Maryland’s programs covering as much as they do, it can turn a needed project into an easy decision.

Maryland Utility & Government Programs

BGE Home Performance with ENERGY STAR (EmPOWER Maryland)

Across most of the greater Baltimore area, Baltimore City and Baltimore, Howard, Anne Arundel, Carroll, and Harford counties, your electric and gas efficiency programs run through BGE as part of EmPOWER Maryland. BGE’s Home Performance with ENERGY STAR program is one of the most generous in the nation: rebates are based on your home’s modeled energy savings and can reach up to $10,000 or 75% of the total project cost, whichever is lower, for a package of air sealing and insulation. The program starts with a home energy audit performed by a BGE participating contractor, requires air sealing before insulation, and includes ventilation to indoor air quality standards, the full trifecta by design. EmPOWER Maryland is authorized through 2032, so this is a stable, active program. You can review current details on BGE’s Home Performance page and see the program cataloged in the DSIRE database.

A great first step with BGE is the free Quick Home Energy Check-up, which identifies where your home is losing energy and installs some no-cost savings items on the spot.

Pepco Home Performance (Montgomery County communities)

Not everyone in the region is a BGE customer. In the northern Montgomery County communities we serve, Olney, Sandy Spring, Brookeville, Ashton, and nearby, your electric utility is Pepco, which runs its own Home Performance with ENERGY STAR rebates under EmPOWER Maryland, along with a comparable moderate-income offering. If Pepco bills you for power, start on Pepco’s site rather than BGE’s, and the program is also listed in the DSIRE database.

EmPOWER Maryland, the umbrella behind it all

Both of those programs are part of EmPOWER Maryland, the statewide energy-efficiency effort overseen by the Maryland Energy Administration and the Public Service Commission and funded through every utility customer’s bill. Understanding that EmPOWER is the source helps explain why the rebates are so consistent from one utility to the next, and why they all lean on audits, participating contractors, and verified results.

Weatherization Assistance Program (income-qualified)

For income-eligible households, Maryland’s Weatherization Assistance Program, administered by the Department of Housing and Community Development through local agencies, provides attic, wall, and floor insulation, air sealing, and blower-door infiltration work at no cost. Eligibility is generally set at 60% of state median income or 200% of the federal poverty level, and priority goes to older adults, people with disabilities, and households with a high energy burden. It is often the best starting point if your household qualifies.

Local incentives and Maryland’s coming Home Energy Rebates

Beyond the utilities, some local jurisdictions offer their own incentives. Baltimore County, for example, has a property tax credit for high-performance homes that rewards deep, whole-home efficiency, and a thorough insulation, air sealing, and ventilation upgrade is part of getting there. Separately, Maryland is standing up federally funded Home Energy Rebates (the HERO and HEAR programs) through the Maryland Energy Administration. As of mid-2026 those programs are still awaiting final federal approval and are not open to the public yet, so it is worth bookmarking the MEA page, but for now the real savings come from BGE, Pepco, and weatherization.

What Happened to the Federal Insulation Tax Credit?

For years, the federal Section 25C Energy Efficient Home Improvement Credit let homeowners claim 30% of insulation material costs (up to $1,200 a year). That credit ended on December 31, 2025, after the 2025 federal tax law accelerated its termination. For insulation installed in 2026 and beyond, there is no federal tax credit.

If your project was completed and placed in service on or before December 31, 2025, you may still be able to claim the credit on your 2025 federal return using IRS Form 5695, so talk to your tax professional. We flag this because some older guides still imply the federal credit is active; in 2026 it is not. We are an insulation contractor, not a tax advisor, so always confirm tax questions with a qualified professional.

How to Use the DSIRE Database for Maryland

The Database of State Incentives for Renewables & Efficiency (DSIRE), run by N.C. State University, is a neutral, comprehensive catalog of energy programs by state. It is a great research starting point: browse the Maryland energy-efficiency programs list (from the Maryland overview) to see utility, state, and local programs in one place, including the BGE residential rebate program, the Pepco program, and the EmPOWER Maryland low-income program.

Treat DSIRE as a directory, not the final word. Program pages point you in the right direction, but rebate amounts, deadlines, and eligibility should always be verified with the utility or agency that administers the program, or confirmed with our team, who works with these programs every week.

Why the Right Contractor Decides Whether You Get Paid

Notice the pattern across every strong program above: BGE and Pepco both require a home energy audit and a participating contractor, air sealing results are verified with a blower door, and the rebate is tied to documented, modeled savings. In other words, the rebate does not just depend on what you install, it depends on who installs it and whether the results are documented. A weekend DIY project, however well intentioned, usually cannot qualify.

Which Insulation Projects Commonly Qualify?

Eligible measures vary by program, but rebates cluster around a handful of high-impact upgrades. A professional assessment pinpoints where your home is actually losing energy, so you fund the fix that pays off.

Attic insulation

Usually the first place we look and the most common rebate-eligible upgrade. A proper attic job seals top plates and penetrations, protects recessed fixtures, preserves ventilation pathways, and adds blown-in or spray foam insulation to the target R-value. In older Baltimore and Howard County homes we routinely find uneven coverage, compressed insulation, and unsealed attic hatches driving up bills.

Air sealing

Insulation and air sealing go together, and Maryland’s programs pay for air sealing because it delivers measurable, verifiable savings. Our crews seal the leaks first, then insulate, the same sequence a blower door test and the BGE program both reward.

Attic ventilation

Balanced intake and exhaust, and, where appropriate, a solar attic fan, keeps heat and moisture from undermining your new insulation. In our humid climate, getting ventilation right is what keeps the whole system healthy year after year, and it is a required part of a qualifying Home Performance project.

Crawl spaces, basements & problem homes

Many Baltimore-area homes sit over crawl spaces or have older, damp basements, which is where cold floors, musty air, and humidity problems often begin. Crawl space encapsulation, along with air sealing and rim-joist insulation, controls that moisture and makes the whole house more efficient. And when old insulation is damaged by moisture or pests, professional insulation removal clears the way for a clean, efficient, rebate-ready upgrade. We handle residential and commercial projects across the metro; you can explore all of our services for local specifics.

Your Rebate-Ready Project, Step by Step

Here is what working with Koala Insulation of the Greater Baltimore Area looks like when a rebate is on the table:

1. Book your free assessment. Call (667) 241-9099 or request a free estimate online. We schedule around you.
2. Home efficiency assessment & written estimate. We evaluate your whole envelope, insulation, air leakage, and ventilation, explain the findings, and provide a tailored, program-aligned scope and quote.
3. Confirm and reserve incentives before work starts. We identify the applicable BGE, Pepco, and state programs and their audit or pre-approval requirements so nothing is done out of order. This is the step that protects your rebate.
4. Professional installation plus blower door testing. Our technicians install premium insulation, air sealing, and ventilation, and document results with blower door testing where the program requires it.
5. Documentation & savings. You receive clean invoices and project records for your application, plus a more comfortable, healthier, more efficient home.

Mistakes That Can Cost Homeowners Their Rebate

• Starting too soon. Doing the work before the audit, pre-approval, or reservation. The utility programs will not pay retroactively.
• Using a non-participating contractor. BGE and Pepco both require a participating contractor and a qualifying audit, so the wrong installer can mean no rebate.
• Skipping the blower door test. Measured rebates need documented before-and-after results; without them, a valid project can still be denied.
• Ignoring the trifecta. Insulating without air sealing and ventilation leaves comfort, moisture control, and rebate dollars on the table, and it is not how Maryland’s program is designed to work.
• Assuming the federal credit still applies. The 25C tax credit ended December 31, 2025.
• Assuming the state IRA rebates are open. Maryland’s Home Energy Rebates are not open yet, so plan around the utility programs in the meantime.

Key Takeaways

• In 2026, utility programs, not federal tax credits, drive insulation savings across the greater Baltimore area.
• BGE’s Home Performance with ENERGY STAR program is among the most generous in the country, up to $10,000 or 75% of a qualifying air sealing and insulation project, with Pepco offering a comparable program in the Montgomery County communities we serve.

Frequently Asked Questions

What insulation rebates are available in the greater Baltimore area in 2026?

For most homes, BGE’s Home Performance with ENERGY STAR program pays rebates on air sealing and insulation based on your home’s modeled energy savings, up to $10,000 or 75% of the project cost, after an audit with a participating contractor. In the northern Montgomery County communities we serve, Pepco runs a comparable program. Income-eligible households can get insulation and air sealing at no cost through the state Weatherization Assistance Program. Maryland’s federally funded Home Energy Rebates are not open yet, and the federal 25C tax credit ended December 31, 2025.

Do these rebate programs require a specific contractor?

Yes. BGE and Pepco both require a home energy audit and work through a participating contractor, and the rebate is tied to documented, verified results. That is why professional installation and documentation matter so much. Koala Insulation of the Greater Baltimore Area performs the work to program standards and provides the paperwork your application needs.

What is the insulation, air sealing, and ventilation trifecta, and why does it matter for rebates?

Insulation slows heat transfer, air sealing stops the uncontrolled leaks insulation cannot cover, and ventilation manages heat and moisture so the whole system stays healthy and performs. Skipping any one of the three limits your comfort and savings. It also matters for incentives: Maryland’s Home Performance with ENERGY STAR program is built around all three, requiring air sealing before insulation and ventilation to indoor air quality standards, so addressing the trifecta together is how you maximize both performance and rebate dollars.

How generous are the Maryland utility rebates, really?

Very. Through EmPOWER Maryland, BGE’s Home Performance with ENERGY STAR program can cover up to $10,000 or 75% of a qualifying air sealing and insulation project, based on modeled energy savings. Amounts depend on your home and are set by the utility, so we confirm current figures for your address before you commit, but Maryland’s programs are consistently among the strongest in the country.

Is the federal insulation tax credit still available in 2026?

No. The federal Section 25C Energy Efficient Home Improvement Credit ended on December 31, 2025. Insulation installed in 2026 or later does not qualify for a federal tax credit, although projects placed in service on or before December 31, 2025 may still be claimed on a 2025 return using IRS Form 5695. Confirm any tax questions with a qualified tax professional.

Does Koala Insulation file the rebate paperwork for me?

No. Koala Insulation does not file rebate applications or tax credits on your behalf, and no contractor can guarantee that a utility or agency will approve an incentive. What we do is provide professional, program-aligned installation, including blower door testing, plus the clear invoices and documentation your application needs, and we point you to the official utility and government pages to apply.

How does blower door testing affect my rebate?

Many air sealing and insulation rebates are based on measured results, and the utility programs verify air-leakage reduction with a blower door test. Koala Insulation of the Greater Baltimore Area offers professional blower door testing, so we can document the improvement your project delivers and support your rebate claim.
