How Woolsey Attic Insulation Was Born
The idea for Woolsey Attic Insulation started with a phone call we didn’t want to take. A homeowner in Los Angeles had paid another company to insulate her attic, and the job ended with a cold spot over her daughter’s bedroom and a receipt she kept in a kitchen drawer because looking at it made her angry. Her name isn’t important. Her story is. She had been told one price, then charged another. She had been given a start time, then waited through an entire Saturday for a truck that never came. And when she finally got someone on the phone, she was told the work looked fine from the photos they hadn’t actually taken.
That call came to Glenn Hartley in 2002, back when he was still working alongside a small crew and noticing patterns he couldn’t ignore. The industry had a habit of treating insulation like an afterthought, something to rush through before the real work began. Homeowners were being handed jargon and fuzzy explanations. Prices shifted after the handshake. And the people doing the work rarely came back when something failed. Glenn saw the problem clearly: nobody was treating a home’s comfort system with the care it deserved, and nobody was putting promises in writing.
So Woolsey Attic Insulation began with a simple promise. Say the price before the work. Show up when you said you would. Leave the home cleaner than you found it. And if something goes wrong, come back and fix it. From that first year in Los Angeles, the company grew location by location, each one independently owned and operated, each one held to the same written standard. Today we serve homeowners across California, from San Diego and Long Beach up through San Jose, San Francisco, Oakland, Fresno, Anaheim, Riverside, Irvine, Santa Ana, and Chula Vista. The home base is Los Angeles, but the promise travels everywhere we do.
Glenn Hartley’s Personal Connection to the Insulation Trade
Glenn Hartley didn’t grow up dreaming about insulation. He grew up in a house where the upstairs bedrooms were always too hot in summer and too cold in winter, and he remembers pressing his palm against the wall of his childhood room and feeling the heat bleeding through in August. Nobody explained why. It was just how houses were. Years later, when he first climbed into an attic and stood under a roof that was trapping heat like an oven, it clicked. All those years of discomfort had a cause. And it had a fix.
He learned the trade the slow way, from the tradespeople who let him watch and ask questions. He remembers the smell of fiberglass dust mixing with the heat of a Los Angeles roof in July, the feel of a tape measure stretched across joists, the sound of a blower machine rattling to life. He learned where air leaks hide, how different insulation materials behave, and why a rushed job shows up in next month’s energy bill. But what kept him in the trade wasn’t the technical work. It was the moment after a job was done, when a homeowner walked into a room that finally held its temperature. That silence. That comfort. He’s been chasing it ever since.
Over the years, that experience turned into something personal. Glenn has worked with GreenFiber cellulose, Owens Corning fiberglass, and Knauf batts and blown-in products, learning which material suits which home and why. He’s been in attics where the old insulation had settled to nothing, and he’s seen the look on a homeowner’s face when they realize their air conditioner wasn’t broken, it was just working against a hot attic. If he weren’t doing this work, he’d probably still be fixing houses somehow. This is what he understands. This is what he’s good at. And every weather complaint from a homeowner sounds, to him, like a problem with a solution.
Meet Glenn Hartley – The Person Behind Every Job
Glenn Hartley, Owner & Founder. Glenn has spent more than two decades in the insulation trade, learning it from the attic down. He built Woolsey Attic Insulation on a conviction that homeowners deserve straight answers, written prices, and work that holds up over time. He’s the one who set the standard every location follows: no surprises, no shortcuts, no disappearing after the job is done.
What separates Glenn from a technician at a corporate chain is accountability. When a Woolsey Attic Insulation job falls short, the correction comes through the same standard he wrote. Glenn is the kind of person who reads installation guides for fun and still gets satisfaction from a cleanly laid batt line. He lives in Los Angeles and keeps a workbench that’s better organized than most kitchens. His personal commitment is this: if you wouldn’t put it in your own attic, don’t put it in someone else’s.
Our Promise to Homeowners
Every Woolsey Attic Insulation location works to the same four promises, and they’re written down so there’s never a question later. First, you get a written price before any work starts. That price doesn’t change at the door. Second, you get a real arrival window, and the tech shows up inside it. Third, the job site is left cleaner than we found it, which means no stray fiberglass in the hallway and no debris left by the curb. Fourth, the work is covered by a written guarantee: if a repair fails inside the guarantee period, we come back and fix it at no charge. Glenn put these promises in place because he saw what happened when companies didn’t. They’re not marketing language. They’re the rules we work by.
