If your power bill spikes every July and every January, the problem usually isn't your HVAC system. It's your attic. Cullman homes sit at a higher elevation than most of North Alabama, which means colder winter nights, humid summers, and an attic that works overtime in both directions. When that attic is under-insulated and leaking air, your HVAC never gets to rest — and you pay for it every month.

Insulation Plus is the #1 insulation company serving Cullman, AL. We're based in Huntsville and we cover all of North Alabama, including Cullman, Hanceville, Good Hope, Vinemont, Baileyton, Holly Pond, Dodge City and the surrounding communities. We're not an HVAC company or a general contractor that does insulation on the side. Insulation and home envelope work is all we do, every day.

Blowing Over vs. Upgrading Your Blown-In Insulation

Most homes in Cullman County were built with blown-in fiberglass or cellulose in the attic — and most of them were built to the code minimum at the time, which is nowhere near what's recommended today. ENERGY STAR recommends roughly R-49 to R-69 in most attics, or about 14 to 20 inches depending on the material. A lot of the attics we open up in Cullman are sitting at 4 to 7 inches.

If your existing insulation is clean, dry and free of contamination, the fastest and most affordable fix is a blow-over: we add new blown-in insulation on top of what's already there to bring your attic up to the recommended R-value. It's a same-day job on most homes, and the difference in comfort — especially in second-story bedrooms and bonus rooms — shows up immediately.

But a blow-over isn't always the right call. Insulation that's been wet, packed down, smoke-damaged, rodent-contaminated or full of construction debris won't perform no matter how much you pile on top of it. Adding new material over bad material just buries the problem. That's when removal is the honest answer, and we'll tell you that up front.

Insulation Removal & Attic Cleanout

Our crews run commercial-grade insulation removal vacuums that pull old material straight out of the attic and into sealed bags — no hauling debris back through your hallway, no mess left behind. We remove blown-in fiberglass, cellulose, and old batts, vacuum the deck and framing, and leave the attic clean and ready for a proper install.

Insulation removal in Cullman homes is usually driven by one of four things: roof leaks and water damage, a rodent infestation, smoke or odor contamination, or insulation that's simply reached the end of its life and settled into a useless mat. In every one of those cases, removal isn't an upsell — it's the only way a new install will actually perform.

Rodent Droppings Cleanup and Attic Sanitizing

Cullman is surrounded by farmland and woods, and that means mice, rats and squirrels find their way into attics constantly. Rodents don't just nest in insulation — they urinate and defecate throughout it, tunnel through it, and destroy its R-value. Contaminated insulation also becomes an indoor air quality problem, because your attic air doesn't stay in your attic. It gets pulled down into your living space through every gap, can light and duct chase in your ceiling.

Our rodent droppings cleanup process is thorough: full removal of the contaminated insulation, HEPA vacuuming, sanitizing and deodorizing the attic surfaces, and then a clean new install. Our team holds IICRC and OSHA certifications, so contaminated-environment work is handled to professional standards — not just shoveled into a trash bag.

Air Sealing: The Step Most Insulation Companies Skip

Here's what separates a real insulation company from a crew that just blows fluff: insulation slows heat transfer, but it does not stop air movement. If your ceiling is full of unsealed penetrations — top plates, wire and plumbing chases, bath fans, recessed lights, the attic hatch, the chimney chase — your conditioned air is escaping straight through the insulation you just paid for.

Before we insulate, we find and seal those leaks with caulk, foam and purpose-built materials. Air sealing is the single highest-return step in most Cullman homes, and it's why we can stand behind our results. Insulation without air sealing is a half-finished job.

Batt Insulation for Crawlspaces, Floors, Walls and Garages

Blown-in isn't the answer everywhere. For crawlspaces, floor systems, knee walls, garage ceilings, bonus rooms and interior sound control, batt insulation installed correctly — cut to fit, no compression, no gaps, in full contact with the surface it's insulating — outperforms a sloppy blow-in every time. We install both, and we recommend based on what your home actually needs.

$300 TVA EnergyRight Rebates for Cullman Homeowners

Insulation Plus is a member of the TVA EnergyRight Quality Contractor Network, which means Cullman homeowners can claim TVA rebates on the work we do — $300 for attic insulation and $300 for whole-home envelope air sealing, for up to $600 back on a single project.

Whether you're served by Cullman Electric Cooperative or Cullman Power Board, both are TVA local power companies, so these rebates are available in the city and out in the county. You don't have to chase the paperwork either — as a Quality Contractor Network member, we submit the rebate request for you after the work is complete. TVA emails you a redemption code and you claim your money. All rebate-eligible upgrades must be completed by a QCN member and meet TVA standards in effect on the installation date, which is exactly why hiring a vetted contractor matters.
