What Is Blown-In Attic Insulation?
Blown-in insulation is loose material, either fiberglass or cellulose, that gets blown into your attic through a hose and settled into an even layer over the attic floor. It’s different from batts, which are pre-cut rolls that get laid between joists. Blown-in fills gaps, settles around wiring and ductwork, and reaches corners that batts leave uncovered. The material itself doesn’t create cold air. It slows heat from moving through your ceiling, so the conditioned air you pay for stays inside your living space longer.
Most of the attics we work in across Fort Worth have blown-in fiberglass already. The problem is the depth. Fort Worth homes built before the mid-2000s were often insulated to R-19 or R-30, which is about 6 to 10 inches. For Texas summers, we usually recommend R-38 to R-49, which is 13 to 18 inches depending on the material. The R-value is the number that measures how well insulation slows heat from moving through your ceiling. Higher R-value means more resistance to heat transfer.
This page is part of our Attic Insulation in Fort Worth guide, which covers every insulation type we offer and how to choose the right one for your home.
When You Need Blown-In Attic Insulation
Not every home needs blown-in attic insulation replaced, but a lot of Fort Worth homes do. Here are the situations we see most often across the city:
- Your upstairs runs 8 to 12 degrees warmer than downstairs in the summer. This is the most common complaint we hear from homeowners in Wedgwood, Ryan Place, and Arlington Heights. Heat builds in the attic, and with too little insulation, it radiates through the ceiling into bedrooms and bathrooms.
- Your energy bill spikes from May through September and doesn’t match your usage. AC units in Fort Worth run hard from late May through early October. If your attic is under-insulated, that system runs even harder. Homeowners with this problem often see bills $60 to $120 higher per month in summer than neighbors with similar homes and proper R-value.
- Your attic insulation looks thin, settled, or has bare spots. Insulation settles over time. Fiberglass and cellulose both compact, especially in high-traffic attics where the HVAC system gets serviced, or where pest control has moved material around. If you can see drywall or studs above the insulation, you need more.
- Your home was built before 2005 and the attic has never been topped off. Fort Worth building codes changed over the years, and even homes built to code in 1995 or 2000 are under-insulated by today’s standards. Topping off brings the attic to current recommended R-value without removing anything.
- Rooms stay comfortable but your heat or AC runs constantly. That’s a sign the conditioned air is leaving the building envelope faster than it should. The attic is usually the biggest culprit. More insulation slows that escape and gives your system a break.
- You’re buying or selling a Fort Worth home and the inspection flagged insulation. Inspectors comment on visible insulation depth, and lenders sometimes require a top-off before closing. We do insulation for both buyers and sellers, and we provide before-and-after photos with every job, which comes in handy for closing documents.
Our Blown-In Attic Insulation Process
Here’s exactly what happens when you book a blown-in attic insulation job with Laurel Attic Insulation Fort Worth:
- You call or book online, and a live person picks up the phone. We answer calls around the clock. You tell us your address, approximate attic size, and what you’re noticing in the house. We schedule a window that works for you and send a confirmation.
- A technician arrives at a live, trackable time. You see the technician’s arrival time the way you’d track a delivery. You don’t wait around from 9 to 2. You know when we’re coming, and we show up in uniform, background-checked, and ready to inspect.
- We inspect the attic and measure the actual square footage and current depth. We look at the existing insulation, check for moisture or ventilation issues, and measure how much material is already in place. Then we calculate what additional R-value your attic needs based on Fort Worth’s climate zone and your home’s layout.
- We send you a written price before any work starts. No vague percentages, no door-step surprises. You approve the exact dollar amount in writing before we move a hose through your house.
- We blow in the insulation to the agreed depth. Our team covers the floor of the attic with fiberglass or cellulose, working around ductwork, wiring, and other penetrations. The material settles into gaps and gets distributed evenly. We set the depth markers, so you can see at a glance that the R-value is correct.
- We send you before-and-after photos and pay from the link on your phone. You see the finished product even if you never climb the ladder. If anything isn’t right, we come back. The 365-Day Done Right Promise covers workmanship for a full year, in writing, on every job.
Blown-In Attic Insulation Pricing in Fort Worth
Most blown-in attic insulation jobs for Fort Worth homes run $1,100 to $2,700. The main cost drivers are the square footage of your attic, the target R-value, and the material you choose. Here’s a realistic breakdown based on local market pricing:
| Job Scope | Typical Price Range |
|---|---|
| Small attic topper (up to 800 sq ft, R-30 to R-38) | $1,100 – $1,600 |
| Medium attic top-off (800 – 1,500 sq ft, R-38 to R-49) | $1,500 – $2,200 |
| Large attic full install (1,500 – 2,500 sq ft, R-49) | $2,200 – $2,900 |
| Fiberglass blown-in material (per sq ft, installed) | $0.90 – $1.30 |
| Cellulose blown-in material (per sq ft, installed) | $0.80 – $1.20 |
Another factor that affects cost is existing insulation removal. If your attic has old, contaminated, or wet insulation that needs to come out first, that adds labor and disposal. Insulation removal in Fort Worth typically runs another $1 to $2 per square foot. We’ll tell you during inspection whether removal is necessary, and we won’t recommend it if a simple top-off will do the job.
Call (817) 730-5474 for an exact quote. Estimates are free, and you get the written price before we do anything, so there’s no pressure to decide on the spot.
Fiberglass vs. Cellulose: What We Recommend for Fort Worth Homes
We install both blown-in fiberglass and blown-in cellulose, and the right choice depends on your attic’s condition and your goals. Fiberglass is moisture-resistant, doesn’t settle as much over time, and carries less fire treatment. Cellulose, made from recycled paper with a fire retardant, fills gaps slightly better and often costs a little less per R-value. Both work well in Fort Worth’s climate.
What we don’t do is push whatever happens to be on the truck. Laurel Attic Insulation Fort Worth stocks materials from eight brands, including Johns Manville, Knauf, and CertainTeed. That range lets us match the material to your attic’s layout, your budget, and the R-value you need. We’ll walk you through the trade-off in plain language, name the actual dollar difference, and you pick.
Is Blown-In Attic Insulation Dangerous?
Blown-in insulation is safe when installed correctly. Fiberglass can irritate skin and lungs if you handle it without protection, and cellulose dust can bother your eyes and throat. Our technicians wear protective gear during installation, and we keep the material out of your living space while we work.
If you’re adding insulation to an attic that has old vermiculite, stop and get it tested. Some vermiculite from before 1990 may contain asbestos. We don’t touch vermiculite until it’s been tested and cleared. We’ll flag it during inspection if we see it, and we’ll tell you your options before any work is scheduled. Your safety is more important than finishing a job.
Blown-In Attic Insulation and Fort Worth Weather
Fort Worth has a humid subtropical climate. That means long, hot summers with highs in the 90s and 100s, and winters that dip into the 30s and 40s. The attic is where your home takes the biggest thermal hit in both seasons. In August, attic temperatures can climb to 140 degrees. In January, the same attic can be 20 degrees at 4 a.m. Insulation works both ways. It slows heat from entering in the summer and slows heat from escaping in the winter.
We also account for humidity. Fort Worth gets 35 to 40 inches of rain per year, and the air is often damp. Blown-in insulation needs good ventilation above it. In attics with poor soffit or ridge ventilation, we check airflow and may recommend attic baffles and ventilation prep before piling on more material. Adding insulation to a poorly ventilated attic can trap moisture, which leads to mold, and we won’t do that. We’ll tell you what we see, and we’ll quote any ventilation correction separately so you know the full picture.

FAQs – Blown-In Attic Insulation
How much does blown-in attic insulation cost in Fort Worth?
Blown-in attic insulation in Fort Worth typically costs $1,100 to $2,700, depending on attic square footage, target R-value, and material choice. Smaller attics and simple top-offs fall on the lower end, while large attics or full replacements run higher. We give you a written price before any work starts, so the number you approve is the number you pay. Call (817) 730-5474 for a free, no-obligation estimate.
Can you do blown-in attic insulation the same day?
We can often inspect and install blown-in insulation on the same day, depending on our Fort Worth schedule and the size of the attic. Most jobs take 3 to 6 hours from arrival to final photos. If you need it done quickly, call (817) 730-5474 in the morning and we’ll tell you what we can fit in that day.
Is blown-in insulation better than batts for Fort Worth attics?
For most Fort Worth attics, blown-in insulation is better than batts because it fills gaps around ductwork, wiring, and irregular joist spacing that batts leave uncovered. Blown-in also reaches corners and edges more fully, which improves overall coverage and effective R-value. That said, attic batt insulation has its place in specific situations, and we’ll recommend what fits your attic rather than defaulting to one method.
How much blown-in insulation do I need in Fort Worth?
The Department of Energy recommends R-38 to R-49 for attics in our climate zone, which translates to 13 to 18 inches of blown-in fiberglass or cellulose. Most Fort Worth homes we inspect have R-19 to R-30, which is well below that. During inspection, we measure your current depth and calculate exactly how much additional material you need to hit the target R-value for your home.
Is it cheaper to repair or replace my attic insulation?
For most Fort Worth homes, it’s cheaper to top off existing blown-in insulation than to remove and replace everything. Removal only makes sense if the existing material is wet, moldy, contaminated by pests, or severely compacted. We’ll inspect before we quote, and we won’t recommend removal if adding material is the better value. Call (817) 730-5474 and we’ll give you a straight answer on your specific attic.
