The #1 Insulation Company in Guntersville, AL: Attic Insulation, Removal, Air Sealing & TVA Rebates

 Insulation Plus is Guntersville's #1 insulation company — blown-in attic insulation, insulation removal, rodent droppings cleanup, air sealing and batt insulation, plus $300 TVA rebates.

Living on Lake Guntersville is about as good as North Alabama gets. Living with a Lake Guntersville power bill in August is another story. Homes here deal with something most of the region doesn't: constant humidity coming off the water, on top of the same brutal summer heat and cold snaps everyone else gets. That combination punishes an attic. If yours is under-insulated and leaking air, your HVAC system runs nonstop trying to keep up, and you feel it every month when the bill comes.

Insulation Plus is the #1 insulation company serving Guntersville, AL. We're based in Huntsville and we cover all of North Alabama — Guntersville, Albertville, Boaz, Arab, Grant, Union Grove, Douglas and the communities all around Marshall County. 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 around Guntersville were built with blown-in fiberglass or cellulose in the attic — and most 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. Plenty of the attics we open up in Marshall County 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 upstairs bedrooms, bonus rooms and lakefront homes with a lot of glass — shows up right away.

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. That matters more here than in most places: humidity near the lake means moisture problems in attics and crawlspaces are common, and damp insulation loses R-value fast. Adding new material over bad material just buries the problem. When removal is the honest answer, we'll tell you 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 Guntersville homes is usually driven by one of four things: roof leaks and moisture 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

Guntersville homes back up to woods, water and farmland, and mice, rats and squirrels take full advantage. Rodents don't just nest in insulation — they urinate and defecate throughout it, tunnel through it, and destroy its R-value. Contaminated insulation is also 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, 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. And in a humid lake climate, those same leaks pull damp outside air into your home, which means higher bills and a muggier house.

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 Guntersville 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. Crawlspaces in particular are common around Guntersville and are often the most neglected part of the house. We install both blown-in and batt, and we recommend based on what your home actually needs.

$300 TVA EnergyRight Rebates for Guntersville Homeowners

Insulation Plus is a member of the TVA EnergyRight Quality Contractor Network, which means Guntersville 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 the Electric Board of Guntersville or Marshall-DeKalb Electric Cooperative, both are TVA local power companies, so these rebates are available in town 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 once 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.
