Meet the San Jose Team Behind Aspen Attic Insulation San Jose
Attics in San Jose aren’t a side job for us. They’re the whole job. The crew you’ll meet below works in some of the hottest, tightest, dustiest spaces this city has to offer, from Willow Glen bungalows to Evergreen two-story builds, and they’ve been doing it long enough to know which corner of an attic holds heat and which one leaks it. What unites them isn’t a slogan. It’s a shared dislike of half-done work and a habit of showing up when they said they would, with a written price in hand before anything gets touched. Garrett Sloane, the owner, built the San Jose crew around one idea: you should know the name of the person going into your attic before they climb the ladder.
Our People
Marcus T. – Lead Technician, San Jose
Marcus has been running attic insulation installs across Santa Clara County for 14 years, five of them with Aspen. He holds current certification for spray foam application and spends more time in Tyvek than most people spend in pajamas. His specialty is the tricky retrofit: tight attic access, unusual framing, homes where the original insulation was installed back when nobody thought R-value mattered. Marcus is the one who catches things other crews miss, like a bathroom exhaust vent pumping moist air directly into loose-fill fiberglass. Off the clock, he rebuilds vintage motorcycles and will talk your ear off about carburetors if you let him. On the clock, he’s all business.
Elena R. – Senior Insulation Installer
Elena came to insulation from residential construction, which is why she reads a roofline the way some people read a freeway onramp. Seven years in attics across San Jose, from Japantown to Almaden, and she’s our go-to for blown-in insulation jobs where coverage density matters. She runs the hoses herself and checks bag yield against square footage, so what’s on the invoice matches what’s in the attic. Elena also handles our material selection calls with the eight premium brands we stock, matching Owens Corning, Rockwool, or GreenFiber to the specific attic rather than reaching for whatever’s closest to the truck. She grows tomatoes in a community garden plot and swears San Jose summer heat is good for at least one thing.
Dana V. – Service Coordinator
Dana is the voice on the phone at (669) 220-7044, and if you’ve called us, you’ve likely already met her. She’s been dispatching home service crews in San Jose for nine years, four with Aspen. Dana keeps the schedule honest, sends you the technician’s name and photo before the visit, and walks every homeowner through the written price before the crew rolls out. She knows the neighborhoods, the traffic patterns, and which days Berryessa Road will eat thirty extra minutes. If something needs to change, she calls you back. No voicemail tennis, no “we’ll be there between eight and whenever.” Dana handles the logistics so the crew can do the work.
Sam L. – Apprentice Installer
Sam joined Aspen two years ago through a trades training pipeline and has been running under Marcus’s wing ever since. He handles material staging, air-sealing prep, and the clean-up that keeps a job site from looking like a fiberglass explosion. Sam is working toward his own spray foam certification and already runs a blower machine solo on straightforward blown-in jobs, checked at every step by a senior installer. He’s the one hauling the heavy bags up the ladder and the one who double-checks that every gable vent is clear before the insulation goes in. Sam was born and raised in San Jose, and he’ll tell you he never once thought he’d end up liking attics. He does now.
Garrett Sloane – Owner, Aspen Attic Insulation San Jose
Garrett founded this San Jose location as part of the Threshold Group family, with roots going back to 2002, and he still walks job sites regularly. You’ll see him in work boots, not a blazer, and he’s been known to describe a 130-degree San Jose attic as “the kind of heat that makes a lizard sweat.” Garrett’s approach is direct: state the problem plainly, explain what fixes it, and hand you a written price before any work starts. He’s the one who put the 365-Day Done Right Promise in writing, covering labor and materials for a full year with a free second visit if a repair fails. Garrett believes a homeowner should never have to wonder who’s showing up at the door, which is why every tech arrives with a name, photo, ID badge, and a marked uniform. If you call and ask to speak with the owner, you’ll actually get him.
One Standard, Every Job
The crew in San Jose operates to what we call The Threshold Standard. It’s not a wall poster. It’s the way every Aspen location runs, and it covers the things homeowners actually care about. Every technician is background-checked and identity-verified before they’re ever scheduled for a home visit. Each one arrives in a clean marked uniform and shows a photo ID badge at the door. Before the visit, you receive the tech’s name and photo, so the person at your door is the person you’re expecting. The written price comes before the work, always. The 365-Day Done Right Promise covers labor and materials in writing, with a free second visit if something isn’t right. That’s the standard, and the San Jose team holds to it on every job, every attic, every time.
