Pricing & Cost FAQs
Attic insulation in Fresno typically runs $1,800 to $4,200 for a standard single-family home, depending on square footage, current insulation depth, and the material you choose. Blown-in fiberglass or cellulose lands on the lower end; spray foam or full removal-and-replacement pushes higher. A 1,500-square-foot attic that needs topping up from R-19 to R-38 usually falls around $2,200 to $2,800. We write every quote as a fixed number before any work starts, so the price you see is the price you pay. Call (559) 785-2658 for a free written estimate.
Yes, blown-in insulation usually costs less per square foot than batt installation because it goes in faster and fills irregular spaces without cutting. In Fresno attics we commonly see blown-in cellulose running $1.20 to $1.80 per square foot installed, while fiberglass batts run $1.50 to $2.50. That said, blown-in isn't always the right call. If you plan to store boxes on attic joists or convert the space later, batts may serve you better. We'll show you the numbers for both and let you decide.
Retrofitting exterior walls in Fresno typically costs $2,500 to $6,000 for a standard home, because the job involves drilling access holes, blowing insulation into each stud bay, and patching. The final number depends on wall count, siding material, and whether we're doing the whole house or one problem room. Homes in neighborhoods like Tower District and Fig Garden often have stucco exteriors, which patch cleanly but add a little labor. We price the full job up front, in writing.
Insulation removal and disposal in Fresno generally runs $1,500 to $3,000 for an average attic. That covers vacuuming out old material, bagging it, and hauling it away. You'd need removal if there's rodent damage, heavy dust contamination, or old vermiculite that should be tested for asbestos before anyone disturbs it. We don't recommend removal unless it's actually necessary, and we'll tell you plainly if a simple top-up would do the job instead. Call (559) 785-2658 and we'll assess it honestly.
Crawl space insulation in Fresno typically ranges from $1,200 to $3,500 depending on square footage, access clearance, and whether we're insulating the floor above or the crawl space walls themselves. Many homes in Clovis and Sanger have vented crawl spaces that lose heat through the floor in winter. Sealing and insulating that area can cut your heating bill noticeably. We'll measure, explain the options, and hand you a written price before anything starts.
Fresno homeowners can sometimes access rebates through Energy Upgrade California or local utility programs, but availability changes year to year and depends on your specific utility provider. PG&E serves most of Fresno and has periodically offered incentives for attic insulation and air sealing upgrades. We don't process rebate paperwork as a guarantee, but we can point you toward current program websites and make sure the work meets their specs if you're pursuing one. Call (559) 785-2658 and we'll talk through what's realistic.
Not really. Insulation pricing in Fresno stays fairly steady year-round because attics are worked in every season, not just winter. The summer heat is actually when we see the most calls, because homeowners feel the ceiling radiating heat in July and August when attics hit 140 degrees or more. If anything, spring and fall tend to be slightly easier for scheduling, but the price doesn't swing meaningfully. The bigger savings come from doing the job right once rather than paying twice for a patch job.
Service & Process FAQs
Most attic insulation jobs in Fresno take one day, typically four to seven hours from setup to cleanup. Wall retrofits might take two days depending on how many walls we're doing and how many access holes need patching. Removal plus re-insulation can stretch to two days. We'll give you a clear arrival window before we come out and we work to that window, which is part of the Kingswell Way. You won't be left wondering if we're showing up.
Yes, we handle attic insulation and exterior wall retrofits throughout the Fresno area, including Clovis, Madera, Selma, and the surrounding communities. Attics are where most heat moves in and out, but walls matter a lot in older homes built before modern insulation standards. Homes in Fresno built in the 1950s and 1960s often have little or nothing in the walls. We'll look at both and tell you where your money does the most good.
The Kingswell Guarantee is a written promise on every job: a fixed price before any work starts, a real arrival window, a clean job site when we leave, and a written guarantee on the work itself. If a repair fails inside the guarantee period, we come back and fix it at no charge. The guarantee is part of how Woolsey Insulation Fresno operates, and it comes in writing, not as a verbal handshake. You'll see it on your paperwork before you sign anything.
Yes, always. We don't start any job without a written price in your hands first. That's one of the four promises every Kingswell company works to. You'll get the number, the scope of work, and the material type spelled out before you commit to anything. No price that changes at the door, no surprise line items. If the scope changes mid-job because something unexpected turns up, we stop and put the new number in writing before continuing.
We will. R-value, air sealing, vapor barriers, cellulose versus fiberglass, knee walls, vent baffles, all of it. We use the trade's real words and then explain what they mean in a sentence or two. Glenn Hartley, who leads our Fresno team, would rather you understand exactly what you're buying than feel like you nodded through a sales pitch. Ask us anything during the estimate. If we can't explain it simply, we shouldn't be selling it.
You can, and most people do. The work happens in the attic and at the access point, so your living space stays usable. Expect a little noise from the blower and some foot traffic at the access hatch. We lay down drop cloths at the entry and the access area as a matter of course; leaving the place cleaner than we found it is a Kingswell Way standard, not a favor. If you'd rather be out for the day, that's fine too. We'll lock up and text you when we're done.
Air sealing should happen before or alongside insulation, because insulation slows heat transfer but doesn't stop air movement. In Fresno attics we commonly seal around recessed can lights, plumbing penetrations, and the top plates of interior walls before blowing insulation. In summer, hot attic air pushes into the house through those gaps; in winter, heated air leaks out. Sealing those first makes the insulation measurably more effective. We'll check for the obvious leak points as part of the estimate.
Brands & Materials FAQs
We work with established manufacturers including Owens Corning and GreenFiber, choosing the material that fits the job rather than pushing one brand onto every project. Owens Corning fiberglass is a common choice for blown-in attics and batt jobs. GreenFiber cellulose is made largely from recycled paper and works well for dense-pack wall retrofits. We'll tell you which material we recommend and why, and the brand name is always on the written estimate.
Both work, and the right answer depends on your attic. Fiberglass blown-in insulation settles less and is lighter, which matters over older ceiling drywall. Cellulose fills odd cavities better and has a higher R-value per inch. In the Fresno climate, where attic temperatures swing from the 30s in winter to 140-plus in summer, either material performs fine if installed at the right depth. We'll recommend one based on your attic's framing, venting, and existing material, and we'll say why.
For the Fresno climate zone, current building science recommends R-38 to R-49 in attics, which translates to roughly 12 to 16 inches of blown fiberglass or 10 to 14 inches of blown cellulose. Many older Fresno homes are sitting at R-11 or R-19 if they were insulated decades ago. That's a big performance gap, and it shows up as a hot ceiling in August and a cold house in January. We'll measure your current depth and tell you exactly what you're at and what you'd need to reach the recommended range.
Yes. If you have existing fiberglass batts and want to top up, we can blow loose-fill fiberglass over them. If you have old cellulose that's settled, we can top it with more cellulose or switch to fiberglass depending on what's there and what condition it's in. The goal is a consistent thermal layer across the entire attic floor, not a patchwork of mismatched materials. We'll check what's up there during the estimate and plan accordingly.
Licensing & Insurance FAQs
Every pro working under our name is required to hold the license and insurance their state requires for the work they do. That's a Woolsey standard and a Kingswell standard, applied at every location, including ours in Fresno. You're welcome to ask us about coverage specifics at the estimate. We'd rather you ask than wonder.
We don't hand your job to an outside crew. The people who show up at your Fresno home are part of the local Woolsey team that Glenn Hartley leads. That keeps the quality consistent and the accountability direct. If something needs follow-up, you're calling the same people who did the install, not chasing down a third party.
Standalone insulation retrofits in existing homes generally don't require a building permit in Fresno, Clovis, or most surrounding cities. That changes if the job is part of a larger remodel that's already under permit. If a permit is needed for your specific project, we'll tell you before we start, and we'll make sure the work meets the local code requirements for the area. No surprises.
Emergency & Response FAQs
Our Fresno team runs a full schedule, but we keep room for estimates and emergency jobs throughout the week. Our normal hours run 7:00 AM to 7:00 PM Monday through Friday and Sundays, with Saturdays closed. If you've got water-damaged insulation or a rodent problem in the attic that can't wait, call (559) 785-2658 and we'll work out the soonest available slot, usually within the week.
Yes. Wet insulation stops insulating and starts growing mold, so a roof leak or plumbing leak in the attic needs a quick response. We pull out soaked material, let the space dry, and re-insulate once the source of the water is fixed. The insulation can't go back in while the leak is still active, so we'll coordinate with your roofer or plumber on timing. Call us at (559) 785-2658 as soon as you spot the water and we'll get you on the schedule.
Yes. We serve Fresno and the surrounding Central Valley communities including Clovis, Sanger, Reedley, Kingsburg, Parlier, Visalia, Chowchilla, Los Banos, Tulare, Madera, and Selma. Our team works throughout the metro and the smaller towns around it. If you're not sure whether we cover your address, call (559) 785-2658 and ask. If we can't get to you, we'll say so rather than stretch the service area.
Our Fresno hours are 7:00 AM to 7:00 PM Monday through Friday, and 7:00 AM to 7:00 PM on Sundays. We're closed Saturdays. That gives us a full Sunday for homeowners who can't take a weekday off for an estimate or install. Book a Sunday slot and you'll get the same crew, the same written price, and the same guarantee as any other day.
Warranty & Guarantees FAQs
Every job we do comes with a written guarantee. If a repair fails inside the guarantee period, we come back and fix it at no charge. That covers our workmanship. The materials themselves carry manufacturer warranties from brands like Owens Corning and GreenFiber, and those terms vary by product. We'll walk you through what's covered, what's not, and for how long, before you sign. The guarantee is in writing, not a promise made over the phone.
The Kingswell Way is the value code every Woolsey location works to, including ours in Fresno. Five rules: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. It's not a marketing slogan. It's the standard Glenn Hartley and the Fresno team are measured against on every job. If we miss on any of those, you have every right to call it out.
Blown-in fiberglass and cellulose insulation lasts 20 to 30 years in a Fresno attic, assuming it stays dry and rodent-free. The material doesn't break down quickly, but it does settle over time, and cellulose can compact in high-moisture conditions if a roof leak goes unnoticed. Most attics we see need topping up every 15 to 20 years to recover lost depth and performance. We'll tell you if your attic truly needs new material or just an additional layer.
Yes. We come out, look at your attic or walls, take measurements, and hand you a written estimate at no charge. The number on that estimate is the price you'll pay if you move forward, no renegotiation at the door. Call (559) 785-2658 and we'll schedule a time that works with your week. Estimates run during our normal hours: 7:00 AM to 7:00 PM, Monday through Friday and Sunday.
