Fast, Reliable Blown In Insulation Across Dallas
Blown in insulation in Dallas runs $1,800 – $4,300 for a typical 1,400 – 2,200 sq ft attic re-blow, depending on current R-value, square footage, and whether we’re adding radiant barrier. Most jobs finish in a single day. We work the same subdivisions you live in: Lake Highlands, Casa View, Preston Hollow, and every 1970s – 2000s tract from Oak Cliff to Far North Dallas. That local familiarity matters because Dallas attics fail in predictable, specific ways. The original fiberglass settles. HVAC techs trample it. Summer heat cooks whatever’s left. If your upstairs runs 15 – 20°F hotter than downstairs every July afternoon, call (940) 748-1726 for a free estimate and a written price before we touch anything.
Why Alden Insulation Dallas Is Dallas’s Preferred Blown In Insulation Company
We’re not the cheapest bid in Dallas, and we won’t pretend to be. Homeowners who call us have usually been burned once already by a contractor who no-showed, raised the price at the door, or left a mess in the attic. Our answer is simple: the written price is in your hand before a single tool comes off the truck. That number is the number on the invoice. Period. Alden Insulation Dallas is independently owned and operated, held to The Garrison Standard, and led by Bryce Holloway. Every technician who steps into your Dallas home is background-checked and in uniform. You’ll know exactly who’s walking through the door, and they’ll arrive inside the scheduled window, not a vague half-day range.
Calls are answered by a live person 24/7. Not a voicemail. Not a form. A real human being who can schedule your estimate. And every job carries the 365-Day Done Right Promise in writing: if the work fails within a full year, we come back and make it right at no charge. That’s a free second visit if the insulation doesn’t perform. That’s what The Garrison Standard means in practice, and it’s non-negotiable on every job across Dallas.
Cellulose Insulation in Dallas
Cellulose insulation is the workhorse material for Dallas attics, and for good reason: it’s dense, it fills irregular cavities, and it holds its R-value better than loose fiberglass in our heat. Where original blown fiberglass settles to half its labeled R-value within a decade, cellulose, installed correctly, resists settling. For Dallas homeowners, the practical difference shows up as a measurable drop in upstairs temperatures and a lower summer electric bill.
Here’s what the job involves: we run a hose into your attic and blow the cellulose to a uniform depth, typically R-38 to R-49 in the Dallas area. Before we blow anything, we air-seal the top plates, can lights, and any penetrations where conditioned air escapes. We also verify your attic ventilation is working. Blowing insulation into a poorly ventilated Dallas attic is like putting a sweater on someone standing in a sauna. You need airflow moving the heat out, not just R-value holding it back. When we use cellulose, it’s often GreenFiber, a brand you can research yourself before committing.
Pricing for cellulose in Dallas typically runs $1.20 – $2.10 per square foot installed, depending on depth and access. A 1,500 sq ft attic getting a full R-38 re-blow usually lands between $2,000 and $3,300.
Air Sealing Before the Blow
We won’t blow new insulation over unsealed penetrations. In Dallas homes, the worst offenders are the top plates over interior walls, bathroom exhaust fans venting into the attic, and the gaps around recessed can lights. Sealing those first stops the stack effect that pulls conditioned air out of your living space and into the attic all summer. It’s unglamorous work, but it’s the difference between a re-blow that performs and one that just looks thicker in photos.
Moldy Cellulose Replacement
Dallas spring hailstorms damage hundreds of roofs every year. When a roof leaks around a bathroom vent or a valley, cellulose absorbs the moisture and turns to mush. It loses all insulation value and holds water against your ceiling drywall. If you’ve had a hail-damage roof repair in the last few years, we should inspect the insulation below the affected areas. We remove the damaged material and re-blow clean cellulose, matched to the surrounding depth.
Blown In Attic Insulation in Dallas
Blown in attic insulation is the core of what we do across Dallas, and it’s the single highest-impact upgrade for a house that’s frustrating to cool. In Dallas’s 1970s – 2000s subdivisions, original blown fiberglass often settles to half its labeled R-value within a decade. Add in AC installers trampling it flat during equipment changeouts, and many attics that should be R-19 or R-30 are effectively R-11 or worse, with bare spots directly over living areas. Re-blowing that attic is the fix.
We offer a full attic assessment with every estimate. Our crew gets up there, measures the existing depth, checks for compressed or missing sections around HVAC registers, and gives you an honest read on what you have versus what you need. Then we quote the work with a written price. No pressure. No vague promises.
Cost for a blown-in attic re-blow in Dallas runs $1,800 – $4,300 for most homes between 1,400 and 2,200 square feet. Smaller ranches in Casa View or Lochwood can come in under $1,800. Larger two-story houses in Lake Highlands or Coppell-adjacent North Dallas can push past $4,500 with radiant barrier included. Call (940) 748-1726 and we’ll give you a specific number, in writing, before any work begins.
Radiant Barrier for Dallas Roofs
Dallas’s brutal, prolonged heat turns under-insulated attics into 140°F+ ovens that radiate heat downward all night. R-value alone can’t stop radiant transfer from a dark asphalt shingle roof baking in 105°F sun. We install radiant barrier under the rafters, which reflects that heat back out instead of letting the attic become a convection oven. Combined with a proper R-38 to R-49 blow, radiant barrier is the local answer to the question every Dallas homeowner asks in August: why is my upstairs still hot at 10 p.m.?
Adding to Existing Insulation vs. Full Removal
Most Dallas attics with older blown fiberglass do not need full removal. If the existing material is dry, free of rodent activity, and not compressed beyond recovery, we can air-seal, re-fluff where possible, and top it with fresh cellulose or fiberglass to reach R-49. Full removal is warranted when the existing insulation is water-damaged, moldy, or saturated with decades of dust and pest debris. We’ll tell you which path your attic needs, with photos, before we quote either one.
Trusted Brands We Service in Dallas
Alden Insulation Dallas installs and removes insulation using products from eight industry-respected brands including Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. For Dallas’s heat and humidity profile, we most often recommend GreenFiber cellulose for attic re-blows and Demilec or Icynene closed-cell foam for specific applications like cathedral ceilings or band joists in pier-and-beam homes. You can research every one of these brands independently before you say yes. That’s the point: what goes into your attic should be a decision you make with open eyes, not a surprise you discover after the crew leaves. We also service and remove existing installations from any of these manufacturers.
Common Blown In Insulation Problems We See in Dallas Homes
- Settled original fiberglass in 1970s – 2000s tract homes. Builders blew R-19 or R-30 once, and it’s been settling and getting trampled by HVAC techs ever since. In a 1994 two-story off Abrams Road in Lakewood, our crew found the original R-19 compacted to a dusty 4 inches around the master bedroom register. The upstairs ran 18°F hotter than the downstairs at 5 p.m. in July. We air-sealed the top plates and re-topped to R-38 with GreenFiber, then added radiant barrier. The owner texted us the next afternoon: the upstairs thermostat had dropped 9 degrees.
- Moldy cellulose around bathroom exhaust fans and hail-damaged roof penetrations. Dallas spring hailstorms crack roof vents and displace shingles, letting water drip into the insulation below. Cellulose absorbs it, turns to mush, and loses all insulation value while holding moisture against ceiling drywall. If your roof got hail repair and the attic wasn’t checked afterward, there’s a good chance some insulation needs replacement.
- Compressed insulation around AC registers and attic scuttle holes. Every time an HVAC tech worked in your attic, they stepped on the insulation around the registers and the attic access. That compression crushes R-19 down to R-11 or worse exactly where you need it most: over the rooms you’re trying to cool. We top-dress those areas specifically, not just blanket the whole attic and hope.
- Bare-spot radiation over living areas. Wind from soffit vents, old roof repairs, and decades of foot traffic can leave sections of the attic floor with almost no insulation. Those bare spots act like skylights of heat over the rooms below. Our post-install thermal scans measure the upstairs/downstairs delta before and after: the goal is dropping that 15 – 20°F gap to under 5°F.

FAQs About Blown In Insulation in Dallas
Most Dallas homeowners see the upstairs/downstairs temperature gap drop from 15 – 20°F to under 5°F after a proper air seal, re-blow to R-38 or R-49, and radiant barrier where the roof design calls for it. We measure this with thermal scans before and after on every job. One Lakewood homeowner saw a 9-degree drop in the upstairs thermostat the day after we finished. Call (940) 748-1726 and we’ll give you an honest read on what your attic can do.
Yes, but cathedral ceilings need a different approach than flat attic floors. The cavity between the ceiling drywall and the roof deck is typically too shallow for a meaningful R-value from blown fiberglass or cellulose alone. We usually recommend closed-cell foam from Demilec or Icynene for those cavities, because it delivers R-6.5 per inch in a tight space and acts as a vapor retarder, which matters in Dallas humidity. A free estimate will tell you what’s in those cavities now and what it will take to fix them.
Usually not. If the existing fiberglass is dry, free of mold, and hasn’t been contaminated by rodents or roof leaks, we can air-seal and blow fresh cellulose or fiberglass right over it. Full removal is only necessary when the old material is water-damaged, moldy, or compressed beyond recovery. We’ll show you photos of what’s up there and make a recommendation you can verify. Estimates are free; call (940) 748-1726.
Dallas’s humidity is a significant concern, especially in pier-and-beam homes and wall cavities. Blown-in cellulose is treated with borates that resist mold, but if there’s an active moisture source, like a leaking pipe or poor crawlspace ventilation, any insulation will eventually fail. We address the moisture source first, then insulate. That’s the only sequence that works long-term in Dallas’s climate.
Yes. Many 1920s – 1950s Lakewood and Highland Park homes have empty wall cavities, and we can dense-pack cellulose into them through small drill holes from the interior or exterior. Dense packing fills the cavity fully and resists settling, which is critical in older Dallas houses where the wall framing may not be perfectly uniform. The improvement in summer comfort is significant, because those empty walls act as solar chimneys that radiate heat all night. Call (940) 748-1726 to schedule a wall inspection and quote.
