Why Woolsey Attic Insulation Is Old Fig Garden’s Preferred Spray Foam Insulation Company
We’ve worked in a lot of Old Fig Garden homes, and they teach us something every time. A 1936 Tudor on North Van Ness won’t insulate like a 1929 Spanish Colonial on East Rialto. Neither will behave like a house built in Clovis in 1995. Woolsey Attic Insulation was founded in 2002 under the Kingswell family of independently owned and operated insulation companies, and Glenn Hartley leads our crew with one rule: see the attic before you price the job.
Every Woolsey technician is background-checked and uniformed. You know who’s walking through your door, and you get a written price before any work begins. No door-step price changes. Ever. We put the Kingswell Guarantee on every job: the written price, a real arrival window, a clean job site, and a written guarantee covering the work for 365 days. If it’s not right, we come back and make it right at no charge. That’s not a slogan. It’s in writing.
Closed Cell Spray Foam Insulation in Old Fig Garden
Closed Cell Spray Foam Insulation in Old Fig Garden is the right choice where moisture control matters as much as R-value, which means most of this neighborhood’s vintage homes. Closed-cell foam cures dense and rigid, around 2 inches thick with an R-value near R-7 per inch, and it acts as an air barrier, vapor retarder, and structural stiffener all at once. Homeowners off Van Ness and Rialto choose it for roof decks, rim joists, and the undersides of vaulted ceilings where original plaster-on-lath meets modern expectations.
A closed-cell job in Old Fig Garden typically runs $3.50 to $6.00 per board foot, and a 1,000-square-foot roof deck usually lands between $4,500 and $7,000 depending on access and how much remediation the substrate needs.
Roof Deck and Vaulted Ceiling Applications
The homes off Van Ness Boulevard with high-pitched Spanish Colonial Revival rooflines often have cathedral ceilings with no attic cavity at all. Closed-cell applied directly to the underside of the roof deck gives you insulation without losing interior headroom. It also seals against the summer heat that pushes uninsulated attic spaces past 150°F in Old Fig Garden.
Rim Joist and Band Board Sealing
Old Fig Garden’s pre-war foundations leave rim joists exposed to Tule fog moisture and winter lows that dip into the 30s. Two inches of closed-cell around the rim stops air movement at the floor line and keeps the cold from wicking up through the original hardwood framing. Most rim joist jobs here take less than a day.
Open Cell Spray Foam in Old Fig Garden
Open Cell Spray Foam in Old Fig Garden gets specified most often for attics with complex roof geometry and for eave bays that a rigid foam board simply won’t reach. Open-cell expands aggressively and cures soft, around R-3.7 per inch, and it half-fills cavities to let existing plaster breathe while still cutting airflow dramatically. It’s lighter than closed-cell, which matters in older framing, and it costs less per square foot.
Open-cell in Old Fig Garden typically runs $1.80 to $3.20 per board foot. A full attic retrofit in a 2,200-square-foot pre-war home usually lands between $2,800 and $5,400, depending on whether we’re air-sealing first, how many eave bays need custom work, and whether the homeowner’s electrician has cleared the knob-and-tube.
Attic Cavity Fills and Eave Bays
The balloon-frame wall cavities common to 1920s and 1930s Old Fig Garden construction were never designed for insulation. Open-cell can be sprayed into awkward eave bays and shallow rafter pockets where closed-cell would over-pressurize the cavity. We keep the profile thin behind original wood soffits so the stucco detailing these homes are known for stays intact.
Knob-and-Tube Clearance Work
Once an electrician has decommissioned active knob-and-tube circuits in the attic, open-cell can be applied across the ceiling deck where the old runs used to sit. This is sequencing work, and it’s specific to Old Fig Garden. Neighboring Fresno neighborhoods built after 1960 almost never face it.
Trusted Brands We Service in Old Fig Garden
Woolsey works with materials from Johns Manville, Knauf, and CertainTeed, among others, and we stock enough to keep an Old Fig Garden job moving without ordering delays. We recommend the material that fits the home, not whatever happens to be on the truck that morning. For a pre-war Spanish Colonial with original plaster and a tight roof cavity, that might be a Johns Manville open-cell formulation. For a rim joist under Tule fog exposure, Knauf closed-cell. You get that honesty in writing before we spray a single pass. Old Fig Garden homeowners call (325) 240-5411 and get a straight answer about what their house needs.
Common Spray Foam Insulation Problems We See in Old Fig Garden Homes
- Knob-and-tube encapsulation by a rushed crew. Active K&T wiring in a 1930s attic gets buried under foam, which violates California code and most insurer requirements. Fixing it means full removal and re-spray, and we see this happen when a contractor quotes from photos instead of walking the attic first.
- Closed-cell applied too thick against plaster-on-lath. Original plaster doesn’t flex like drywall. A thick, rigid foam pass can trap moisture from Tule fog season and blister the interior ceiling. Old Fig Garden homes need a measured approach, not a maximum-coverage approach.
- Eave bays and original wood soffits getting blocked. Standard eave vents and modern rafter spacing don’t exist in these homes. A crew that assumes they do ends up sealing airflow entirely, which is exactly what you don’t want under a 150°F summer attic.
- Flat spray on a multi-pitch roof deck. Old Fig Garden rooflines rarely run straight. Seven pitches, dormer intersections, and curved Mission-style eaves demand multiple passes at varied depths. One-coat-everywhere work leaves thermal gaps that show up on the August cooling bill.

FAQs About Spray Foam Insulation in Old Fig Garden
Does Old Fig Garden’s knob-and-tube wiring stop a spray foam insulation job?
Yes, if the knob-and-tube is still live. California code and most insurers prohibit encapsulating active K&T with spray foam, so the job pauses until a licensed electrician decommissions or replaces those circuits. On a 1930s Spanish Colonial Revival off Van Ness Boulevard, our crew opened the attic and found original knob-and-tube runs feeding two ceiling fixtures and a bath fan, plus a balloon-frame eave bay that was never framed for a foam pass. We documented the K&T, had the homeowner’s electrician decommission those circuits, then spray-applied closed-cell across the vaulted ceiling and used open-cell on the rafter bays over the plaster-on-lath knee wall. The homeowner’s August peak-hour runtime dropped noticeably, and we left the soffit intact. Call (325) 240-5411 and we’ll walk your attic before we quote so you know exactly where you stand.
Can closed-cell spray foam go on a 1920s Spanish Colonial Revival roof deck in Old Fig Garden?
Yes, closed-cell can be applied directly to a 1920s roof deck, and it’s often the best choice for those cathedral ceilings with no attic cavity. The deck needs to be structurally sound and dry, and we keep the thickness appropriate for plaster-on-lath below so we don’t trap Tule fog moisture against the original plaster. Most roof deck jobs in Old Fig Garden run $4,500 to $7,000 for a 1,000-square-foot area.
Why is spray foam different in Old Fig Garden than in a Fresno subdivision built after 1980?
It’s different because the houses are different. Old Fig Garden is defined by large, individually designed residences in Spanish Colonial Revival, Tudor Revival, and Mediterranean styles built mostly between the 1920s and 1940s. Balloon-frame wall cavities, inaccessible eave bays, and original wood-framed soffits are common obstacles that add scope and cost. A Fresno tract house built after 1980 has predictable framing, modern electrical, and attic spaces engineered for insulation. Old Fig Garden demands a flashlight walk, an electrical assessment, and a foam plan tailored to each individual roof line.
Does Tule fog season affect which spray foam you use in Old Fig Garden?
Yes. Tule fog brings weeks of cold, dense moisture from late fall through winter, and that changes the math on vapor management. Closed-cell foam acts as a vapor retarder and is often better for roof decks and rim joists facing persistent fog exposure. Open-cell breathes more and works well in attics with existing ventilation. We match the material to the exposure, and we do it in writing before we spray.
How do you handle spray foam in Old Fig Garden’s tight attics and inaccessible eave bays?
We don’t skip them, and we don’t guess. Our crew carries the spray equipment to reach shallow rafter pockets and balloon-frame cavities that rigid boards can’t fill. For eave bays blocked by original wood soffits, we keep the foam profile thin and leave the original detailing intact. That’s the kind of care these 1920s-to-1940s homes require, and it’s why we walk the attic before we quote. Call (325) 240-5411 for a free estimate.
