The Brands Behind Every Grizzly Install
We don’t install mystery material. Every Arvada project uses products from the industry’s most trusted manufacturers.
01THE PROBLEM
Your Ceiling Is a Sixty-Year Renovation Archive.
The typical Lakewood ranch has been remodeled four or five times since the Eisenhower era: swamp cooler in, swamp cooler out, new lighting, new furnace, maybe a whole-house fan. Every project punched holes toward the attic, and almost none of them were sealed afterward. Your furnace pays for that history every night.
AThe swamp-cooler hole nobody closed
Half of mid-century Lakewood cooled itself with evaporative coolers, and when AC arrived, the ceiling chases stayed. We find fist-to-furnace-size openings under the insulation in Morse Park and Eiber attics constantly, sealing one is often the single biggest win of the visit.
BPlaster that cracked its way to the attic
Lath-and-plaster ceilings develop hairline networks at every joint and fixture. Individually they are nothing; across 1,200 square feet they add up to a permanently open window between your living room and the attic.
CCan lights that punched through the past
Recessed lighting retrofits are Lakewood’s favorite upgrade and its leakiest. Each older can cut into a plaster ceiling vents warm air like a chimney, we cap them with airtight, insulation-rated covers without touching your fixtures.
DWind pressure that multiplies every gap
On the Green Mountain side, chinook gusts pressurize homes and force air through gaps that would barely leak on a calm day. The windier your street, the more air sealing returns, west Lakewood is where it pays most.
02THE FIX
Seal It Standalone, or Seal-Then-Top. Both Done Right.
If your insulation is healthy, sealing alone sharpens it. If it is thin, sealing first is what makes the top-off worth buying. We tell you which house you have.
03WHAT TO EXPECT
Four Hours in the Attic. A Report You Can Hold.
How a Lakewood air-sealing visit actually unfolds:
We crawl the full ceiling plane and log every legacy opening, cooler chases, fan holes, plaster cracks, cans, and mark each for its sealing method.
Existing material gets peeled back at each find and folded back after. Nothing is removed unless it is hiding damage.
Foam for framing gaps, rigid patches for cooler chases, fire-rated flashing at flues, airtight covers on cans, and caulk in the plaster networks.
Weatherstripping, rigid insulation, and a latch turn the hatch from the biggest hole in the ceiling into its best-sealed square foot.
Every sealed point photographed and listed by location and material, a completion ledger you can keep with the house records.

Three ways the net cost drops
Xcel Energy rebates
Air sealing is a rebated measure in Xcel territory, and pairing it with insulation stacks the payout.
Federal 25C tax credit
30% of qualifying insulation costs, up to $1,200 per year, under the Inflation Reduction Act.
The multiplier effect
Sealing makes every inch of insulation above it work at rated value, it upgrades what you already own.

"They found the old swamp-cooler chase in our Belmar ranch, wide open under the insulation since 1978. Sealed it and eighteen other spots in an afternoon. The hallway draft we blamed on the front door is gone."

05QUESTIONS
Air Sealing in Lakewood, Answered Straight
Because they have been remodeled for sixty years. Swamp-cooler chases, abandoned flues, retrofitted lighting, and cracked plaster each opened a path to the attic, and almost no project sealed what it cut. The ceiling ends up leaking like a window that never closes.
It is the least expensive job in weatherization, typically a small fraction of an insulation project, priced by gap inventory, ceiling type, access, and hatch work. Plaster ceilings take more labor than drywall. The quote is itemized in writing after a free inspection.
Methodically: we trace every penetration from the attic side, lifting insulation at fixtures, chases, and framing joints. Legacy openings like cooler chases are big enough to find by hand; the plaster networks show up along joints and fixtures. Everything gets logged and photographed.
Yes, when your insulation is already adequate. Sealing restores the performance the leaks were stealing, drafts fade, rooms even out, and the furnace cycles less. If your insulation is thin, we will show you the math for doing both at once instead.
Barely. The crew works from the attic with hand tools and sealants, most homes take half a day, and nothing inside your living space is touched except the hatch. You can work from home through the whole visit.
Not at this scale. Mid-century Lakewood homes leak so generously that ceiling sealing brings them toward healthy, not airtight. We seal the attic plane, the place where leakage costs you most, and the house keeps breathing normally everywhere else.
