Blown-In Attic Insulation in Dallas, TX
Blown-in attic insulation in Dallas typically costs $1,800 to $4,600 for a standard 1,500 – 2,500 sq ft home, with most projects completed in a single day. The material is blown through a hose into your attic floor cavities, creating a dense thermal blanket that cuts the brutal Texas heat from reaching your living space. At Alden Insulation Dallas, we install and remove blown-in insulation using products from Rockwool, CertainTeed, and GreenFiber, every job backed by the 365-Day Done Right Promise in writing.
If your attic insulation is thin, settled, or simply old, you’re paying more every single month to cool air that escapes through your ceiling. Our crews serve homeowners throughout Dallas, from Lakewood to Preston Hollow to Bishop Arts, and we do it with a written price in your hand before any work starts.

This page is the specific guide to blown-in work; for the broader picture, start with our Attic Insulation overview or the Attic Insulation in Dallas page.
Here’s the short version of what a Dallas homeowner gets with blown-in insulation:
- Lower cooling bills. Blown-in insulation slows radiant heat from a 140°F attic from bleeding into your home. That’s the difference between your AC cycling on every 15 minutes and every 40.
- Even coverage. Blown-in material fills the weird corners, narrow eaves, and odd joist spacing that batts leave exposed.
- A faster job. Most attics are done in 4 – 7 hours, not multiple days.
- Written accountability. Every Alden job includes a written guarantee valid for 365 days. If the work fails, we come back at no charge.
When You Need Blown-In Attic Insulation
Dallas attics take direct abuse from May through September. Roof deck temperatures climb past 130°F, and without enough insulation, that heat pours into your home through the ceiling. Here are the signs that your existing insulation has stopped doing its job and you need blown-in material installed:
- Your upstairs is 8 – 12 degrees warmer than downstairs. This is the most common complaint we hear in two-story homes in Lake Highlands and North Dallas. The attic is heating the ceiling below it, and no amount of AC balancing fixes that.
- Your attic has fiberglass batts that are compressed, stained, or missing entirely. Batts shift, rodents nest in them, and old insulation flattens over time. Once compressed, fiberglass loses most of its R-value. Blown-in material fills the gaps batts leave behind.
- Your home was built before 2005 and you’ve never added insulation. Dallas building codes from that era didn’t require the insulation levels needed to handle today’s heat loads. Many homes in Richardson or Garland suburbs have R-19 or less when the attic should have R-38 to R-60.
- Your energy bill spikes every summer. If July and August add $180 – $320 to your bill while you keep the thermostat at the same setting, your attic is almost certainly under-insulated.
- Ice dams in winter, oddly enough. Dallas gets the occasional ice storm, and warm attics melt roof snow unevenly. A properly insulated attic stays cold, preventing those roof-edge ice buildups that cause water damage.
- You can see the tops of your ceiling joists. If the joists are visible above the existing insulation, you’re under-insulated. Period. You should not be able to see the framing.
If any of these match what you’re seeing, get it checked. The fix is straightforward: we blow new insulation over the old material (provided the old material is dry and mold-free) to bring the attic up to the R-value your home needs for Dallas’s climate.
Our Blown-In Attic Insulation Process
We keep this process tight and predictable so you know exactly what’s happening at every step. Here’s how a typical blown-in insulation job goes at Alden Insulation Dallas:
- Inspection and measurement. We measure the square footage of your attic, check the current insulation depth and condition, and identify air leaks around plumbing stacks, light fixtures, and top plates. We also check for moisture issues that would need to be addressed before insulation goes in.
- Written price before work starts. You get a written number in your hand before a single tool comes off the truck. That number covers the material, labor, and cleanup. No surprises at the invoice.
- Air sealing (when needed). Blown-in insulation works dramatically better when we seal the air bypasses first. We seal around can lights, bath fans, and top plates as needed, then proceed with the insulation. This is part of doing the job by the book, not an upsell.
- Blowing the insulation to target depth. Using calibrated equipment, we blow the cellulose or fiber to the exact depth required to hit your target R-value. For Dallas, that’s typically R-38 to R-49 in most homes, sometimes R-60 in newer builds with high-efficiency HVAC.
- Leveling and cleanup. We rake the material flat so coverage is even corner to corner, then we clean up. The attic access gets sealed back, and the area around the hatch is left better than we found it.
- Verification and write-up. We document the final depth and R-value, and we give you the written 365-Day Done Right Promise. If the insulation settles or fails within that year, we return at no charge.
Every technician who walks into your Dallas home is background-checked and uniformed. You’ll know who’s in your attic, and we’ll be inside the window we scheduled.
Blown-In Attic Insulation Pricing in Dallas
Most blown-in attic insulation projects in Dallas run $1,800 to $4,600, depending on attic square footage, current insulation depth, and whether air sealing is needed, so how much does attic insulation cost? (2026 Price Guide) - Dallas, TX depends on your specific situation. The pricing below is what we currently see on the ground in Dallas, not national averages that don’t account for local labor rates and attic conditions.
| Project Scope | Typical Cost Range in Dallas |
|---|---|
| Attic under 1,000 sq ft, blown-in to R-38 | $1,800 – $2,800 |
| Attic 1,000 – 1,800 sq ft, blown-in to R-38 or R-49 | $2,400 – $3,600 |
| Attic 1,800 – 2,500+ sq ft, blown-in to R-49 or R-60 | $3,000 – $4,600 |
| Air sealing (if not already done) | $400 – $800 added to project |
| Removal of old, contaminated insulation before new blow-in | $1,200 – $2,800 added |
These ranges are based on the work Alden Insulation Dallas has completed in North Dallas, Mesquite, Irving, and the surrounding metro. The final number depends on how much insulation is already up there and whether we need to pull out old material first due to rodent damage or moisture.
We install blown-in fiberglass and blown-in cellulose. For Dallas attics, we often recommend blown-in fiberglass because it doesn’t settle as much in our humid climate, and it holds its R-value even in the high attic temperatures we get here. CertainTeed’s InsulSafe and Owens Corning’s AttiCat are both solid fiberglass options we install regularly. For homeowners who prefer a denser, more fire-resistant option, GreenFiber cellulose is another tested choice. Rockwool’s blown-in product is one we recommend for those who want maximum sound dampening plus thermal performance, particularly in homes near Love Field flight paths or busy corridors like Central Expressway.
You should also know: if your attic already has insulation and we’re topping it off, we install new material right over the old layer, provided the old material is dry and hasn’t been contaminated. That saves you the removal cost.

Why Dallas Homes Need More Insulation Than the National Average
A home in Minnesota gets a cold attic that helps keep heat in. A home in Dallas gets a hot attic that’s actively working against your air conditioner for six months of the year. The same R-38 attic that handles a Chicago summer comfortably will struggle in Dallas’s July heat. We recommend R-49 or higher for most Dallas attics, especially if you have a second story or your AC unit is older than 10 years.
Blown-in insulation works because it slows conductive heat transfer through your ceiling. In summer, the attic air heats up to 130°F or higher, and that heat radiates down through your ceiling joists into your living space. A thick, even layer of blown-in insulation acts as a thermal break, keeping the living areas below dramatically cooler. That means your AC doesn’t have to work as hard, and your bedroom doesn’t cook every afternoon.
In winter, the same insulation holds heat inside your home, so your furnace runs less. Dallas gets real cold snaps in January and February. The same attic that overheats in August lets heat escape all winter if it’s under-insulated. Blown-in insulation fixes both seasons at once.
One more thing specific to Dallas homes: humidity. Our climate produces elevated attic moisture, especially around bathroom vents that vent into the attic instead of outside, which is a problem we see often in older Dallas houses-proper attic baffles & ventilation prep can help address this. Blown-in fiberglass is resistant to moisture and does not support mold growth, unlike some older organic materials. That’s a real advantage in a Dallas attic, and it’s one reason we recommend CertainTeed and Owens Corning products for most local homes.
FAQs – Blown-In Attic Insulation
How much does blown-in attic insulation cost in Dallas?
Blown-in attic insulation in Dallas typically costs $1,800 to $4,600, depending on attic size and current insulation depth. Smaller attics under 1,000 sq ft usually run $1,800 to $2,800, while larger attics of 2,500 sq ft or more run $3,000 to $4,600. Call (940) 748-1726 for an exact quote based on your attic’s measurements; the estimate is free.
Is blown-in insulation better than batt insulation for a Dallas attic?
Blown-in insulation is generally better than attic batt insulation for Dallas attics because it fills all the gaps, corners, and odd joist spacing that batts leave exposed. It also creates a continuous thermal blanket with no seams, which matters in a climate where attic temperatures hit 130°F in summer. Batts work, but they require more careful installation, and in older Dallas homes with variable joist spacing, they rarely cover as completely as blown-in material.
How long does blown-in insulation last in a Dallas attic?
Blown-in fiberglass insulation lasts 30 to 50 years in a Dallas attic, provided the attic stays dry and there is no rodent activity. Blown-in cellulose lasts 20 to 30 years and may settle slightly over time, but settlement is usually minimal when installed properly. Any insulation will fail faster if there’s a roof leak or animals have nested in it, so we check for those issues before installing anything.
Can you blow insulation over existing insulation?
Yes, we can blow new insulation directly over existing insulation as long as the old material is dry, uncontaminated, and free of mold or rodent damage. This is the most cost-effective option for most Dallas homeowners because it avoids the cost of removal. If we find moisture or contamination during the inspection, we’ll recommend removal first and show you the written price for the full job before any work proceeds.
Do you remove old insulation before blowing in new insulation?
We only remove old insulation when it’s necessary: rodent contamination, mold, moisture damage, or severe settling. Otherwise, we blow new material over the existing layer to bring the attic up to the target R-value. Removal adds $1,200 to $2,800 to the job cost, depending on attic size and access, so it’s good news for your budget if your old insulation is still in acceptable shape.
Will blown-in insulation actually reduce my energy bills?
Yes. Homes in Dallas that get their attics brought up from R-19 to R-49 typically see cooling season savings of 10 to 25 percent, depending on the age and efficiency of their AC system and how leaky the attic was before. The exact savings depend on your house and your energy use patterns, but a properly insulated attic is the single highest-impact improvement for lowering cooling costs in the Dallas climate.
