The work usually takes one day, and Woolsey Insulation Dallas gives you a written price before any material goes into your attic. Call (469) 916-4622 and we’ll walk you through exactly what your Attic Insulation in Dallas project needs.

Blown-in insulation, sometimes called loose-fill, is exactly what it sounds like: insulation that gets blown into your attic through a hose rather than rolled out in batts. The machine fluffs the material and the hose directs it into every corner, around trusses, and over ceiling joists. For most Dallas homes built before 1990, the existing attic insulation is usually a thin layer of fiberglass batts that leaves gaps around recessed lights, plumbing vents, and electrical penetrations. Blown-in fills all of it. No seams, no gaps, no wasted coverage.

We’re Woolsey Attic Insulation, part of the Kingswell family of independently owned and operated insulation companies. We’ve been installing our Attic Insulation services since 2002. Glenn Hartley leads our Dallas crew. We only do attic and spray foam insulation. We don’t sell roofing or windows or HVAC, and we won’t pitch you anything you don’t need. If your attic needs blown-in insulation, that’s what we’ll quote and that’s what we’ll install. Every job includes The Kingswell Guarantee: a written price before work starts, a real arrival window, a clean job site, and a written guarantee on the work, with a free return visit if anything fails within 365 days.

Wool was the first insulation. Woolsey keeps the idea in the name.

When You Need Blown-In Attic Insulation

Most Dallas homeowners don’t think about their attic insulation until the house gets uncomfortable or the utility bill jumps. Here are the signs we see most often when we inspect attics across Dallas, from Lakewood to Preston Hollow to Oak Cliff:

• Your upstairs rooms run 8 to 12 degrees warmer in July and August. Dallas summers push attic temperatures above 140 degrees. Thin insulation lets that heat radiate through the ceiling all afternoon. Blown-in insulation creates a deeper, continuous thermal barrier that old batt insulation simply can’t match.
• Your energy bills spike every summer, even when your thermostat hasn’t moved. When your attic insulation settles or degrades, your air conditioner works harder to hold the same indoor temperature. Adding blown-in insulation to R-38 or R-49 levels slows that heat transfer dramatically.
• You can see the tops of your ceiling joists. If the insulation in your attic is level with or below the joists, you’re likely under R-19. Modern guidance for North Texas is R-38 to R-49. Blown-in material builds height fast and covers the joists themselves, which batt insulation never does.
• You feel drafts near ceiling fixtures in winter. Gaps around recessed lights, attic hatches, and ceiling fans let conditioned air escape. Blown-in material gets into those tight spaces and seals them by simple coverage.
• Your insulation is old, dusty, or has pest damage. Rodents and raccoons tear through batt insulation and leave droppings. Blown-in replacement gives you a clean, uniform layer that covers the mess and restores the thermal barrier without requiring a complete batt tear-out in every case.
• You’re in a home built before 2000 and the attic has never been touched. North Texas building standards have changed. Many pre-2000 homes have R-11 to R-19 in the attic, which is half or less of what a Dallas attic should carry today.

If any of these sound familiar, call (469) 916-4622. We’ll schedule an attic inspection and tell you honestly whether blown-in insulation is the right fix, or whether your money is better spent elsewhere.

Our Blown-In Attic Insulation Process

Every Woolsey job runs the same way, what we call The Kingswell Way: say the price, show up in the window, leave it cleaner than you found it, put the guarantee in writing, and come back if it fails. Here’s how it works on a blown-in attic insulation install in Dallas.

1. Attic inspection and measurement. We walk the attic, check current insulation depth, look for air leaks, note access points, and measure square footage. We also check for vent baffles – the channels that keep soffit vents open so air can flow. If they’re missing or collapsed, we’ll note that before quoting, because blocking airflow is a common cause of summer heat buildup.
2. Written price before any work starts. You get a written quote with the material, the R-value target, the square footage, and the total price. No door-step surprises, no “we discovered something” upcharges. The price we quote is the price you pay. This is the single most important difference between Woolsey and the contractors Dallas homeowners have been burned by before.
3. Material selection matched to your house. We work with eight leading insulation brands, including Rockwool, CertainTeed, and GreenFiber, so the material fits the home, not whatever happens to be on the truck. For most blown-in attic jobs, we recommend fiberglass for consistent R-value per inch or cellulose for denser, air-slowing coverage. We’ll explain the trade-offs in plain language and let you decide.
4. Prep and install. Our background-checked, uniformed technicians arrive in the committed window. We lay drop cloths from the entry to the attic hatch, set up the blowing machine, and install to the R-value we quoted. The hose reaches into every corner of the attic, so we don’t have to trample through your entire attic space to get coverage.
5. Cleanup and walk-through. We clean up every piece of debris, vacuum any overspray, and leave the job site cleaner than we found it. Then we walk you through what we installed, show you the depth, and confirm the R-value meets what we wrote in the quote.
6. Written guarantee. You receive the Kingswell Guarantee in writing: 365 days, in writing, included on every job. If anything’s not right within that year, we come back and make it right at no charge.

We don’t rush this process. A typical Dallas attic takes four to six hours, depending on size and access. If your attic hatch is in a tight closet or hallway, we’ll protect the surrounding area before we start and clean it thoroughly when we’re done.

Blown-In Attic Insulation Pricing in Dallas

Most blown-in attic insulation jobs in Dallas run between $1,800 and $4,200, and we give you the exact written number before any work starts. Here’s How Much Does Attic Insulation Cost? (2026 Price Guide) - Dallas, TX. Here’s a breakdown of what drives the price.

Factor	Typical Range in Dallas	Notes
Attic square footage	$1.20 to $2.10 per sq ft	Based on area to be covered, not total home square footage
Material (fiberglass)	$0.60 to $1.00 per sq ft	CertainTeed and Johns Manville fiberglass both perform well in North Texas
Material (cellulose)	$0.50 to $0.90 per sq ft	GreenFiber cellulose is a common choice for older Dallas homes
Air sealing add-on	$300 to $800	Foam or caulk sealing around penetrations before blowing insulation – optional but often worthwhile
Old insulation removal	$1.00 to $2.00 per sq ft	Required if existing insulation is wet, moldy, or pest-damaged
Attic hatch insulation and sealing	$150 to $300	Often overlooked; a sealed hatch stops a major air leak

What actually moves the price in Dallas:

• Current insulation depth. If you’re going from R-11 to R-49, that’s more material than going from R-30 to R-38. We measure before we quote, so the number reflects your attic, not a generic estimate.
• Attic accessibility. A pull-down ladder in a hallway is faster and easier than a ceiling hatch in a bedroom closet. Access issues add time, not materials, and we’ll tell you upfront if that affects the quote.
• Air sealing scope. Sealing gaps around recessed lights, plumbing vents, and top plates before blowing insulation can cut your energy loss by 10 to 15 percent. It adds cost, but it often pays for itself within a year or two in Dallas summers.
• Target R-value. The U.S. Department of Energy recommends R-38 to R-49 for attics in North Texas. Going to R-49 costs more than R-38, but the incremental cost is small relative to the total job. We’ll quote both options and let you choose.

Most Common Problems We See in Dallas Attics

After 20 years of insulating attics in Dallas, we can tell you exactly what’s happening up there without even climbing the ladder. Here are the problems we run into week after week.

Inadequate soffit ventilation getting buried

In neighborhoods like Bluffview and Casa Linda, where homes date back to the 1950s and 1960s, soffit vents get covered with old insulation or simply were never installed properly. When we blow insulation over a blocked soffit vent, the attic stops breathing and temperatures climb. That’s why we check and install Attic Baffles & Ventilation Prep as standard practice before any blown-in job. If we don’t, we’re making your problem worse while making your attic look better. We won’t do that.

Insulation settlement in homes built before 2000

Cellulose and fiberglass both settle over time. In a Dallas attic, 20 years of summer heat cycles compress loose-fill insulation, especially in areas where foot traffic from cable installers, pest control visits, or HVAC work has packed it down. If your attic insulation has settled more than a few inches, its R-value has dropped with it. Blown-in installation gives us the chance to start fresh with a uniform depth that we measure and document.

Missing insulation over exterior walls

This is a Dallas classic, particularly in ranch-style homes in Richardson and Garland built in the 1960s and 1970s. The attic floor insulation stops six to twelve inches short of the exterior wall top plate, leaving a cold stripe around the entire perimeter of the ceiling. Blown-in insulation with a well-aimed hose fills that gap. Batt insulation never does, because batts are cut to standard widths and the installer rarely trims the edge precisely.

Recessed lights leaking conditioned air

Older recessed can lights are not air-tight. Warm air from your living room rises through the fixture, bypasses the insulation, and exits through the attic vents in winter. In summer, hot attic air pulls back down through the same openings. Before we blow insulation over recessed lights, we seal them properly and maintain the required clearance for fire safety. This is also a fire-safety issue we’re careful about: blown-in insulation must never be piled directly against a non-IC-rated recessed light housing.

If anything in that list matches what you’ve seen in your own attic, call (469) 916-4622 and we’ll give you an honest assessment.

Types of Blown-In Insulation We Install

We recommend two types of blown-in insulation for Dallas attics, and we’ll explain why we choose one over the other for your specific house.

Fiberglass loose-fill

Blown-in fiberglass, from brands like CertainTeed and Johns Manville, holds its R-value well in high heat and doesn’t absorb moisture the way cellulose can. It’s lightweight, which matters if you have a ceiling that was never designed to carry much weight. In Dallas attics where we’re adding a new layer over existing batts, fiberglass is often the simple answer. It covers fast, reaches into corners, and stays fluffy through decades of Texas summers.

Cellulose loose-fill

Cellulose, including GreenFiber, is made from recycled paper treated with fire retardant. It’s denser than fiberglass, so it slows air movement better, which makes it a strong choice in older Dallas homes with lots of small air leaks in the attic floor. The trade-off is that it settles more, so we calculate the installed depth to account for settlement and still hit the R-value we quoted. We don’t guess. We measure.

We also work with Rockwool loose-fill for specific applications, but fiberglass and cellulose cover the vast majority of blown-in attic work in Dallas. We’ll tell you which one we’d choose for your attic and why. No upsell, no brand loyalty games.

FAQs – Blown-In Attic Insulation

How much does blown-in attic insulation cost in Dallas?

Blown-in attic insulation in Dallas typically runs between $1,800 and $4,200 for a standard 1,500 to 2,200 square foot attic, depending on target R-value, material choice, and whether old insulation needs removal first. You’ll get an exact written quote before any work starts, and that price is guaranteed. Call (469) 916-4622 for a free estimate.

Is blown-in insulation better than batt insulation for a Dallas attic?

For most Dallas attics with irregular joist spacing, roof trusses, and lots of penetrations, blown-in insulation performs better than batts because it fills every gap and covers the joists themselves. Attic Batt Insulation leaves seams, gaps, and compression points that reduce effective R-value. The exception is a wide-open attic with standard 16 or 24 inch joist spacing, where batts can work fine – but we’ll tell you if that’s your situation rather than selling you material you don’t need.

Can you install blown-in insulation over existing insulation?

Yes, you can blow new insulation directly over existing batt or loose-fill insulation in most cases, as long as the existing material is dry, mold-free, and not pest-damaged. We check for moisture, sagging drywall, and signs of roof leaks before we add anything on top. Adding material over a leak or a wet spot just locks in the problem and guarantees a bigger repair later.

How long does blown-in attic insulation last in Dallas heat?

Blown-in fiberglass and cellulose both last 20 to 30 years or more in a Dallas attic, provided the roof stays dry and no pests or roof leaks damage the material. The bigger issue is settling: cellulose may lose a few inches of loft in the first year, which we account for when we install it. If you notice summer upstairs temperatures creeping back up after 15 or 20 years, it’s worth a quick inspection. Call (469) 916-4622 and we’ll take a look.

Is blown-in attic insulation safe around recessed lights and wiring?

Blown-in insulation is safe around wiring and recessed lights as long as proper clearances are maintained. Older non-IC-rated recessed lights must have a barrier keeping insulation at least 3 inches away from the fixture to prevent overheating. We inspect every recessed light before we blow insulation, and if we find non-IC-rated fixtures, we’ll seal them with a proper cover and maintain the required clearance. Electrical and fire safety comes before adding material.
