Fast, Local Attic Insulation

Most Attic Insulation projects in San Francisco are estimates we can schedule within 48 to 72 hours of your call, and installations themselves typically run one to two days depending on attic size and access. If you’re dealing with an emergency situation, such as a roof leak that soaked your insulation and you need it removed before mold sets in, tell the person who answers the phone. We keep slots open for exactly that kind of call and can often get a technician to you same-day.

Our crews work throughout San Francisco proper, from the Sunset and Richmond districts through Noe Valley, the Mission, Bernal Heights, and up into the hills where older homes carry insulation from decades past. We also cover the East Bay, the Peninsula, and Marin communities within a reasonable drive. The phone number is answered by a person, not a voicemail tree, 24 hours a day. If it’s 2 a.m. and you’re worried about a damp attic, call. You’ll talk to someone who can tell you what’s urgent and what can wait until morning.

We don’t do vague scheduling. When you book, you get a window, and we arrive inside it. Every technician is background-checked and uniformed, so the person at your door is exactly who we said we’d send.

How Much Does Attic Insulation Cost in San Francisco?

Attic Insulation Replacement in San Francisco typically runs $2,200 to $6,800 for a full attic, depending on square footage, current R-value, and whether we’re blowing in new material over existing insulation or removing old insulation first. Smaller partial jobs, such as topping off a single attic bay or addressing a specific cold spot, can land between $800 and $1,800. Here’s the breakdown by typical project type:

These ranges reflect what we see across San Francisco’s housing stock, which spans 1920s stucco bungalows in the Sunset, mid-century row houses in Parkside, and newer builds in Mission Bay that still sometimes skimp on attic insulation. Your written quote will reflect your attic as it actually is, measured, not an estimate from a photo or a drone. That’s the point of the written price: the number you approve is the number on the invoice.

What Affects Attic Insulation Cost in San Francisco

Three main factors move the number. The first is square footage of the attic floor. A 900-square-foot attic costs less than a 1,600-square-foot attic, all else equal. The second is the current R-value, which tells us how much material is already up there and whether removal is necessary. Homes built before 1980 in San Francisco often carry R-11 or R-19 fiberglass batts when they should be at R-38 or higher for our climate. The third is access. Some San Francisco attics are full-height walkable spaces. Others are crawl-in hatches in a hallway ceiling where a technician works bent over for six hours. Tight access adds labor time, and labor time is part of your quote.

Removal of old insulation also affects cost. If you’ve had rodents, raccoons, a roof leak, or decades of dust packed into your attic, the old material has to come out before new material goes in. We use commercial vacuum extraction equipment that pulls old insulation out without dragging it through your living space. That work is priced by attic size and material condition.

We install insulation from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. Those are the eight brands we trust, and they’re all names you can research independently before you commit. Your quote will name the specific product and the R-value we’re installing to, because that’s the kind of clarity a written price should have.

What to Look For in a San Francisco Attic Insulation Company

San Francisco has no shortage of insulation contractors. Here’s what separates the ones worth hiring from the ones that’ll leave you with a thin layer of insulation and a hard-to-reach phone number.

Written Prices, Not Estimates That Move

Some contractors quote a number over the phone and revise it at the door. Others give a range and tell you the real number after the work starts. Alden’s rule is simple: the written price is in your hand before a single tool comes off the truck. That number doesn’t move. It’s part of The Garrison Code, the operating standard that’s governed every Garrison Partners job since 2002.

A Guarantee in Writing

Every Alden job carries the 365-Day Done Right Promise. If the work fails within a year, for any reason, we come back and make it right at no charge. That includes a free second visit inside the guarantee window. The guarantee is written on your invoice, not spoken as a handshake. If your attic develops a cold spot six months after we insulate it, call. We’ll be back.

You Know Who’s in Your House

Every technician who steps through your door is background-checked and uniformed. We tell you the name of the person coming before they arrive. It’s a small thing until you’ve had a contractor send an unknown subcontractor to your door, and then it matters a lot.

A Live Person on the Phone

Call Alden at (559) 245-9792 any time, day or night, and a human answers. Not a phone tree, not a form submission, not a callback request. A person. That’s a Garrison Standard requirement, and it’s how we’ve run the business from the start.

What R-Value Does a San Francisco Attic Need?

For San Francisco’s climate, which maps to DOE climate zone 3C, the recommended attic insulation level is R-30 to R-60, with R-38 being the common target for homes with existing insulation in good shape. If your attic currently has old R-19 batts, you’re roughly halfway to where you should be. Heat rises, and in a city where fog rolls through in July and heating bills run year-round, an under-insulated attic is the single largest source of heat loss in most homes.

R-value is a measure of resistance to heat flow. Higher is better for keeping conditioned air in your living space and unheated air in your attic. We’ll measure what you have, tell you the number, and propose exactly what’s needed to get to the target. No upsell, no vague language. Just the number.

Blown-In Insulation vs. Batts: What We Recommend

For most San Francisco attics, Blown-In Attic Insulation is the better choice. Blown-in fiberglass and cellulose settle into the irregular corners, narrow bays, and low-clearance areas that make San Francisco attics challenging. Batts work in some situations, particularly in full-height attics with uniform joist spacing, but blown-in material simply does a better job of covering the whole attic floor without gaps.

We install blown-in fiberglass from Owens Corning and Johns Manville, cellulose from GreenFiber, and mineral wool from Rockwool when the project calls for it. For air sealing, which is the step most insulation companies skip, we seal gaps around recessed lights, plumbing penetrations, and top plates before insulation goes in. Air sealing is what makes R-38 actually perform like R-38.

Do You Need Insulation Removal Before Installing New Insulation?

In many San Francisco homes, yes. Here’s how to know if removal is the right first step:

• Rodents or wildlife. If rats, raccoons, or squirrels have been in your attic, the old insulation is contaminated. It should come out.
• Water damage. A past roof leak or ongoing condensation can compress and contaminate insulation. Wet insulation loses its R-value fast.
• Mold or mildew. San Francisco’s fog and marine air mean attic moisture is a real issue. Moldy insulation should be removed, not covered over.
• Old, compressed material. Insulation that’s been walked on, flattened by storage, or simply broken down over 40 years is not doing its job.

Removal uses a commercial vacuum system that extracts old material directly from the attic into a sealed container outside your home. The process is clean, contained, and typically takes one to two days. After removal, we’re working with a clean slate and can air seal properly before installing new insulation.

San Francisco’s Climate and Your Attic

San Francisco doesn’t get the brutal heat of the Central Valley or the deep freezes of the Midwest, but our climate punishes attics in its own way. Fog pushes moisture into attic spaces. Marine air rusts ductwork. Homes in the Sunset and Richmond sit in fog for months at a time, and that persistent dampness reduces the effectiveness of insulation and invites mold. An attic that’s properly insulated and sealed holds up better against exactly these conditions.

We see this pattern regularly in Sunset District homes built in the 1930s and 1940s, where original insulation has long since packed down to a thin, ineffective layer. We see it in Bernal Heights and Noe Valley homes where roof remodels left the attic unsealed around the eaves. And we see it in Daly City and Pacifica homes where the fog is even thicker and the moisture problems are worse. The fix is the same: remove what’s compromised, seal what’s leaking air, and blow in new insulation to the right R-value.

The Process: What Happens When You Call Alden

1. You call. A live person answers and asks about your attic: age of the home, any known issues, whether you’re topping off or starting fresh. If it’s an emergency, we’ll tell you what we can do and when.
2. We schedule a visit. A background-checked, uniformed technician comes out, walks your attic, measures square footage, checks current R-value, and looks for air leaks, moisture, and access issues.
3. You get a written price. Before any work starts, you have a written quote in hand. It names the product, the R-value, the scope of work, and the total cost. That’s the number you’ll pay.
4. We do the work. Installation typically takes one to two days. We cover your living space, run hoses carefully, and clean up after ourselves. The attic is left better than we found it.
5. You get a written guarantee. Every job includes the 365-Day Done Right Promise. If anything fails within a year, we return and make it right. No charge.
