We’re Alden Attic Insulation, part of the Garrison Partners family since 2002. Bryce Holloway leads our operation, and every job in Tiburon runs on The Garrison Standard: a written price in your hand, a background-checked uniformed crew on site, and a 365-Day Done Right Promise in writing. No vague half-day arrival windows. No price changes at the door. Just a straight answer about what your attic needs and what it costs.

Why Alden Attic Insulation Is Tiburon’s Preferred Blown In Insulation Company

Tiburon homeowners call us because we answer the phone. Not a voicemail, not a call center queue, not an online form. A live person picks up 24/7 at (254) 272-5876. That matters when you’ve got a cold bedroom in January or an attic inspection scheduled before a real estate close on the bay side of the peninsula.

Our technicians arrive in uniform, background-checked, inside the scheduled window. We install products from Owens Corning, Knauf, and GreenFiber, and every job carries a written 365-Day Done Right Promise. If the work fails within that year, we return at no charge. That guarantee is not optional boilerplate. It’s the same standard applied across every Garrison Partners location since 2002.

We also understand Tiburon’s terrain in a way a San Rafael or Novato outfit might not. Hillside lots above Paradise Drive, narrow streets near Blackie’s Pasture, older homes along Tiburon Boulevard with original framing. These aren’t obstacles to us. They’re the conditions we plan around every week. Learn more about our local reach on the Blown In Insulation in Tiburon page.

Loose Fill Insulation in Tiburon

Loose fill insulation in Tiburon is the most common blow-in application we handle, and it’s usually the right answer for open attics with standard framing. The material, typically fiberglass or cellulose, is blown through a hose into the attic floor cavity until it reaches a uniform depth matched to your target R-value. In Tiburon, we generally recommend R-38 to R-49 for attic floors, which means 12 to 16 inches of loose fill depending on the product.

What makes this local work different is the wind. Hilltop attics above Old St. Hilary’s and along Ridge Road get wind-scoured. We’ve opened attics where the loose fill had drifted to the center of the space, leaving the outer 3 feet of ceiling with almost nothing above it. That’s a classic Tiburon failure mode, and it means the rooms below the eaves run cold even though the house “has insulation.”

Coverage and venting done the Tiburon way

When we blow loose fill into a Tiburon attic, we also check the soffit vents. Homes on the canyon side of the peninsula run humid in the summer, and blown-in material that bridges vent channels traps moisture behind it. We install baffles at the eaves before we blow, so air still moves. It is a small step that prevents a much larger problem.

What loose fill costs here

For a typical 1,200 to 1,800 square foot Tiburon attic, loose fill insulation runs $1,650 to $3,800. Larger homes, multiple attic zones, or attics that need old material removed first will land higher. The written estimate you approve is the number on the invoice, always.

Blown In Insulation Contractors in Tiburon

Blown in insulation contractors in Tiburon are not all the same breed, and we say that knowing full well how it sounds. The difference comes down to process. Our crews show up with a written scope of work and a written price. We don’t bid low and revise at the door. We don’t send a salesperson who’s never held a blower hose. We send Bryant’s team, background-checked and uniformed, and they get the job done inside the window we promised.

For Tiburon homeowners, that discipline matters. Hillside access is tight. Parking along narrow roads near Elephant Rock or up on Lyford Drive means planning. We coordinate dispatch from our San Francisco Bay Area office, and crews serving Tiburon are routed to arrive when parking and access windows are realistic, not aspirational.

Attics that need more than just more insulation

We regularly find original 1950s and 1960s Tiburon homes that were built with no air sealing at all. Someone blew insulation over leaky top plates 30 years ago and the performance gain was half what it should have been. Before we blow new material, we air-seal the penetrations: top plates, plumbing stacks, wire chases, can light gaps. That is the difference between insulation that looks good in a photo and insulation that actually stops heat loss.

What a full contractor-grade job includes

A complete blown in insulation job in Tiburon includes inspection, air sealing, baffle installation at the eaves, the blow-in itself, and a post-job depth verification so you know exactly what R-value you paid for. Written guarantee covers it all for 365 days.

Trusted Brands We Service in Tiburon

We install and remove insulation using products from eight industry brands, but for Tiburon attics we typically reach for GreenFiber cellulose, Owens Corning fiberglass loose fill, or Knauf blown-in fiberglass depending on the attic’s condition and the homeowner’s preference. You can research every one of those products online before you commit. We’ll never introduce a mystery material. Our trucks carry common replacement stock for Tiburon jobs, which means faster turnaround when you need a quick attic top-up before weather turns or an inspection deadline hits.

Common Blown In Insulation Problems We See in Tiburon Homes

• Settled or wind-scoured loose fill in hilltop attics. Open-bay attics above the ridge line lose fill at the outer edges, leaving the ceiling perimeter under-insulated. We see this constantly in homes along Ridge Road and on the exposed slopes above Paradise Drive.
• Bridged vent channels in kneewall and low-slope cavities. Blown-in material migrates into soffit vents and chokes airflow, which traps moisture in the attic. That moisture shows up as mildew on the roof sheathing or ice-cold ceilings in the upstairs rooms.
• Original 1950s and 1960s homes with no air sealing. These houses along Tiburon Boulevard and in the flats near Main Street got insulation added at some point, but the top plates and penetrations were never sealed. The result: you paid for R-value you’re not actually getting.
• Half-finished attic conversions with mismatched insulation zones. Attics partially converted to living space often have loose fill in one bay, batts in another, and open gaps above the kneewalls. We map the attic and bring the whole thing up to a consistent R-value.
