Why Even Air Insulation Is Westwood’s Preferred Attic Insulation Company
We built our reputation in the northern Sierra by treating every attic as its own puzzle. Westwood’s housing stock spans three distinct eras, and each one fails differently in a long freeze. Mill-era homes with plaster-and-lath walls need a different approach than a 1970s ranch or a manufactured home with a shallow roof cavity. Homeowners here tell us the same thing: other contractors quoted them a single product before even looking in the attic. We don’t do that.
Nelson Quirarte founded Even Air Insulation around a simple idea – match the material to the application, not to the warehouse shelf. That’s why we carry options like CertainTeed fiberglass, GreenFiber cellulose, and Icynene spray foam. A Westwood attic at 5,000 feet has different demands than a coastal crawlspace. Our method depth means we can dense-pack cellulose behind lath walls, blow fiberglass across an attic floor, or seal a roof deck with open-cell foam. Each job starts with what the house actually needs.
Radiant Barrier in Westwood
Radiant barrier in Westwood is a reflective attic-floor or roof-deck layer that cuts summer heat gain, and here it runs $850 to $2,200 depending on the attic footprint and whether it’s stapled to the rafters or laid over existing insulation at the floor. It’s not a replacement for insulation, but it reduces the surface temperature of the attic floor on those 90-degree July afternoons when the sun hammers a dark roof. Most Westwood homes that benefit are ranch-style builds from the 1960s through 1980s with asphalt shingles and minimal original reflective protection.
When a radiant barrier makes sense here
If your upstairs rooms cook in summer despite decent attic insulation, a radiant barrier addresses the radiation component that fiberglass batts don’t touch. It works best with at least R-30 beneath it and proper ventilation above. In Westwood’s dry climate, it also holds up well, since moisture-driven corrosion isn’t a big concern the way it is on the coast.
What to expect during install
We roll the barrier across the attic floor or staple it beneath the rafters, trimming around can lights and framing. The attic needs to be reasonably clean first, which is why many homeowners pair this with an attic cleaning. You’ll notice the difference in the first hot spell.
Attic Cleaning Services in Westwood
Attic cleaning services in Westwood typically run $700 to $1,800 for a full removal of old insulation, rodent droppings, and debris, then sanitizing and prepping the space for new insulation. Older homes here – especially mill-era company houses – collect decades of dust, squirrel nests, and compressed batts that have lost their thermal value. A clean attic is also the only way to properly air seal top plates and spot wiring problems before they’re buried again.
Why cleaning often precedes insulation
You can’t dense-pack cellulose over a rodent nest and expect good results. The old material has to come out, the joist bays need inspection, and then air sealing can happen. In Westwood homes with knob-and-tube wiring, this is also when we identify circuits that need an electrician’s eyes before anything gets covered.
When cleaning alone is worth it
Some attics have decent insulation depth but poor air quality from old vermin activity or construction debris. In those cases, a full clean-and-sanitize improves indoor air and lets you keep the existing insulation. We’ll tell you honestly if replacement is actually needed.

Trusted Brands We Service in Westwood
We’re brand-literate on purpose. CertainTeed fiberglass batts are a workhorse for open attic floors, and we stock common widths locally so Westwood jobs don’t stall waiting on material runs from Reno or Chico. For retrofit walls in older homes, GreenFiber dense-pack cellulose fills irregular bays and gets around the framing inconsistencies in mill-era construction. When a roof deck needs air sealing and an R-value boost in one pass, Icynene open-cell foam earns its keep. We carry Demilec for closed-cell applications where moisture or structural rigidity matters. The point of a multi-method roster is simple: you never get pushed toward a product we happen to overstock.
Common Attic Insulation Problems We See in Westwood Homes
- Settled insulation in mill-era houses. Original 1920s-through-1950s batts compress to a fraction of their labeled depth, leaving top plates bare and heat pouring into the roof deck. A top-up gets R-value back where it belongs.
- Knob-and-tube wiring buried by a previous owner. This is the shortcut that fails inspection and creates a real fire risk. We flag it on nearly every job in the older blocks near the old mill site and require an electrician’s sign-off before covering any active K&T circuits.
- Ice dams from air bypasses. Westwood’s deep snow load and long freezing nights push warm interior air up through unsealed penetrations, melting snow at the eaves where it refreezes. The fix is air sealing, not just more insulation.
- Thin or missing insulation in manufactured homes. Mobile and manufactured homes on the town’s outskirts often have shallow roof cavities and minimal original insulation. Blown-in cellulose or low-rise foam work better than standard batts in those tight spaces.

FAQs About Attic Insulation in Westwood
Older mill-era homes here, especially those built for Red River Lumber Company workers, frequently still have knob-and-tube wiring in attic bays and wall cavities. That wiring cannot legally be buried under insulation, and doing so creates a fire hazard. We identify active K&T circuits during the attic inspection and ask that a licensed electrician isolate or replace them before we dense-pack or blow over those bays. It’s a delay, but it’s the right delay in Westwood’s original company housing blocks.
R-49 to R-60 is the right target for a Westwood attic, which usually means 14 to 18 inches of blown fiberglass or cellulose above the top plates. Code minimums assume milder winters than Westwood actually gets. With design temperatures pushing below zero and snow sitting on the roof for months, the extra depth pays back fast. Call (855) 362-0195 and we’ll measure your current depth and tell you what it would take to get there.
No. Manufactured homes have much shallower roof cavities and different framing, so standard R-30 batts often won’t fit. We typically use blown-in cellulose or low-rise spray foam for those spaces, and the work goes faster because walls and floors are accessible differently. The goal is the same – real heating-season performance – but the method is matched to the structure.
Ice dams form when warm attic air melts snow at the roof deck and the melt refreezes at the cold eaves. The fix starts with air sealing every top plate penetration, can light, and interior wall opening, then ensuring soffit and ridge venting are balanced. On some older Westwood homes, baffles need to be added before insulation goes in so the roof deck stays cold. We check venting and ice-dam risk on nearly every attic job here.
Cleaning removes old material, debris, and contaminants from the attic floor so you can start fresh or keep existing insulation that’s still performing. Replacement means the old insulation has lost too much R-value through settling, moisture, or age, and new material has to go in. Cleaning costs $700 to $1,800; full replacement runs $1,800 to $4,600. Call (855) 362-0195 and we’ll tell you honestly which one your attic actually needs.
