Attic air sealing in Evansville IN - leaks closed before insulation goes in
Hot upstairs, drafty rooms or a power bill that keeps climbing? We find the gaps in your attic and seal them so your insulation can work.
Why is my upstairs still drafty with insulation in the attic?
Attic air sealing in Evansville means closing the gaps in your ceiling, where the wall tops meet the drywall and around pipes, wires, lights and the hatch, so house air stops leaking up into the attic. It's the step that comes right before insulation, and it's what lets that insulation do its job.
Most of the attics I look at in older Evansville homes already have insulation up there, sometimes plenty, piled over gaps nobody sealed, so the house still breathes like a screen door. The price turns mostly on how many gaps there are and how hard they are to reach, and the schedule turns on whether something has to be fixed before we seal, so you'll get your own figure at the estimate, and before work starts we check with the building office that covers your address about a permit.
How we handle attic air sealing
I start by looking at what's actually up there, because some attics aren't ready to seal yet, and if yours needs a fix first I'll tell you which one. Once the attic's ready, our crew pulls the insulation back at the edges and seals where the wall tops meet the ceiling, around pipes and wires, and around the hatch, which is the one gap almost every attic has. Big holes get solid blocking, and hot flues get metal around them, because foam has no business touching a flue. Older can lights that aren't rated to touch insulation can be boxed in with fire-rated covers, though federal guidance calls swapping them for new insulation-contact rated fixtures the better fix. We keep the soffit, ridge and gable vents and any combustion air ducts open, because they only work open, and then the insulation goes back over a ceiling that's finally tight.
Sealing usually goes hand in hand with retrofit insulation, topping up or replacing what's already in the attic, and sealing always goes first in that pair. Spray foam insulation seals and insulates in one pass, but it costs more, so for most attics I'd seal the gaps and top up the loose fill instead. The exception is an attic with ductwork running through it, where foam usually earns its price.

The owner writes your estimate
I come out, look at your attic and write the estimate myself, and our own crew does the work with me on most jobs. The person who saw your attic is usually the one up there sealing it.
Leaks sealed before anything's added
I started this business in 2023 after years away from the trade, and coming back I kept seeing insulation piled on top of leaks nobody sealed. We seal first, because insulation over an open gap just hides the draft.

What attic sealing work looks like
What people ask about attic air sealing
What is the best order to seal and insulate an attic?
Seal first, then insulate. Federal guidance written for homes nationwide puts combustion safety and indoor ventilation first, then attic ventilation, then air sealing, so if you're planning new insulation, the sealing is the step just before it.
What problems have to be fixed before attic air sealing?
Federal guidance says to hold off when the attic has live knob and tube wiring, the old kind strung on porcelain knobs, vermiculite insulation or bath fans venting into the attic. A leaking roof, an unvented kerosene heater or an unvented gas fireplace also puts the job on hold until each one is fixed, and I'll tell you at the estimate which comes first.
Do I need my furnace checked when I air seal the attic?
Yes, if it burns gas or oil, because federal guidance says to have a heating and cooling technician check gas- or oil-fired furnaces, water heaters and dryers for proper venting. If you have gas appliances, plan on a heating tech checking them as part of the job.
How do I tell where my attic is leaking air?
Look for insulation that's turned dark, because it's been filtering dusty house air, and for frosty patches in cold weather or water stains in warm weather at the same spots. The leaks are usually worst where walls meet the attic floor, over dropped ceilings and soffits, and behind or under kneewalls, the short walls in a finished attic room.
Do I need a permit for attic air sealing in Evansville?
Ask before work starts, because Evansville requires building permits before any interior or exterior alteration, and its list names work like HVAC and drywall but not attic air sealing. Projects should start with a call to the Area Plan Commission about any requirements, and the Building Commission makes sure codes are met on alterations and repairs to homes in Vanderburgh County. We ask the office that covers your address, and when the job calls for a permit, we handle it.
How much does attic air sealing cost in Evansville?
It depends on your attic, since we don't work from a set price. Size, how easy it is to move around up there, whether old insulation has to be pulled back or hauled out, fixes that have to come first and old can lights that need covers or new fixtures all move the number, and choosing foam over sealing plus loose fill raises it. I'll give you your own figure after I've seen the attic.
Work that often goes with attic sealing
- Retrofit insulation
If the insulation already in your attic is thin or settled, adding to it after the seal is what finishes the job.
- Spray foam insulation
When ductwork runs through the attic, foam seals and insulates in one pass and usually pays for its higher price.
