Fast, Reliable Attic Insulation Across Arlington
Most attic insulation jobs in Arlington run between $1,800 and $4,300 for a full top-up or replacement, with smaller single-room or garage attics landing around $900 to $1,400. That’s the range we quote most often, and we’ll give you the exact number in writing before any work starts. We’re Topside Attic Insulation, and we’ve been sealing and insulating homes across Arlington since we opened under The Haven Standard in 2016. If you’re calling from north Arlington, south Arlington, or anywhere between I-20 and I-30, we can typically have a crew at your door within 24 to 48 hours. Call (218) 261-7714 and a live person answers, day or night.
Why Topside Attic Insulation Is Arlington’s Preferred Attic Insulation Company
Arlington homeowners call us because we do something most insulation contractors don’t: we test the house before and after. A blower-door test, a pressurization reading that shows in one number how much air your home is losing, tells us exactly what we’re working with. We publish those before-and-after numbers on every applicable job. You don’t have to take our word that the work mattered; the CFM50 reading drops, and you see it in writing.
Our crews know Arlington’s housing stock the way a mechanic knows a specific engine block. The 1980s brick-veneer ranches off Matlock Road, the two-story tracts near Lake Arlington, the 1970s subdivisions west of Cooper Street: we know what’s in those attics because we’ve been inside thousands of them. Every tech is background-checked and uniformed. Every job closes with a Documented Photo Record so you can see what was done up there without climbing a ladder. And every job starts with a flat, written price. No work begins without it. That’s Haven Standard Clause 1, and we haven’t wavered from it since Wes Okafor founded this company.
We answer the phone 24/7. Not a voicemail tree, not a callback window. A person. That matters when your AC is running nonstop in August and you want answers now.
Our Attic Insulation Services in Arlington
Blown-In Attic Insulation
Blown-in fiberglass or blown-in cellulose is the most common retrofit we do in Arlington, and for good reason. It fills the irregular cavities and settles into the corners of a 1970s or 1980s attic faster and more completely than batts ever will. We source from Johns Manville, Knauf, and CertainTeed depending on the application and the existing material in your attic. In Arlington’s heat, we typically recommend an R-38 to R-49 final depth across the attic floor, which usually means adding 10 to 14 inches on top of whatever is already there.
Attic Batt Insulation
Batts still make sense for specific situations: cathedral ceilings, knee walls, and areas where you need a clean, friction-fit installation against a vertical surface. In Arlington’s older homes, we often find batt insulation that has fallen away from the drywall at eaves, leaving a thermal bypass that lets 150°F attic air press directly into the living space. We remove the failed material and re-install properly, sealing the air gaps first so the new batts actually do their job.
Attic Insulation Top-Up
A top-up is exactly what it sounds like: we blow additional insulation over the existing layer to bring the total depth up to current code. In Arlington, this is the single most common job we quote. The original blown-in fiberglass in homes built between 1975 and 1995 has compacted to 3 to 4 inches in most cases, roughly R-11, when it was spec’d at R-19. Blowing R-30 to R-38 on top gets those attics back to performance without the cost of a full removal. We air-seal first, always. Never insulation over an unsealed attic floor.
Attic Insulation Replacement
Sometimes the old material is too far gone: it’s been soaked by a roof leak, shredded by rodents, or contaminated with decades of dust and debris. In Arlington’s 1970s-era homes, we also see batt insulation that has turned brittle and fallen apart. In those cases, we remove everything, sanitize the attic deck, seal every penetration, and install fresh insulation to R-38 or better. You get a clean slate and a documented before-and-after blower-door reading showing what changed.
Attic Baffles & Ventilation Prep
Before we add insulation, we check what’s happening at the eaves and ridge. Arlington’s flat, open terrain means North Texas wind pushes dust and insulation particles into soffit vents constantly. By the time we open a 1980s attic, the soffit baffles are often clogged or missing entirely. We install or replace baffles to keep airflow moving from soffit to ridge while keeping insulation off the vent openings. Proper ventilation drops attic temperature, which means your ductwork isn’t working against a 20 to 30 degree higher differential in July.

Trusted Brands We Service in Arlington
We install and service blown-in fiberglass and batt systems from Johns Manville, Knauf, and CertainTeed. We don’t lock you into one proprietary product: we spec the material that fits the job and the existing assembly. For Arlington’s older tract homes, that usually means a fiberglass product with proven resistance to settling. We keep common materials stocked and ready for Arlington jobs, which means faster turnaround when your attic is already half-insulated and you want the job finished before the next heat wave.
Common Attic Insulation Problems We See in Arlington Homes
- Compacted original blown-in fiberglass. Homes built in the 1970s through the 1990s were insulated to minimal codes, and that material has settled hard. We routinely find 3 to 4 inches where there used to be 8 to 10. That’s R-11 doing the job of R-19 or better.
- Batt insulation fallen away from the drywall. In Arlington’s 30 to 50 year old tract homes, batts at eaves and around light fixtures have pulled loose over decades of temperature cycling. The gap lets superheated attic air pour into the living space all summer.
- Clogged soffit and ridge vents. North Texas wind pushes dust and dry grass into attic vents. After 30 years, most Arlington attics have substantially reduced airflow, which traps heat and forces your HVAC to work harder than it should.
- Ductwork in unconditioned attics. A huge share of Arlington homes route HVAC ducts through the attic. When the attic hits 140 to 150°F in July and August, the ducts are conducting heat into the air you pay to cool. Insulation on top of sealed ducts changes the entire equation.

FAQs - Attic Insulation in Arlington
If you can see the tops of your ceiling joists, you’re under-insulated. In Arlington’s 1980s tract homes, original blown-in fiberglass has almost always settled to 3 to 4 inches, which is R-11 or less. The telltale signs: upstairs rooms that never cool evenly, AC running nonstop from June through September, and an Oncor bill that climbs every summer. We’ll come inspect it and tell you exactly what depth you have and what you need. Call (218) 261-7714 for a free assessment.
In most Arlington homes, yes. Because so much ductwork runs through unconditioned attics that exceed 140°F in summer, insulation upgrades have an outsized effect. We’ve had customers text us their Oncor bill was down 15 to 22 percent within one billing cycle after a top-up. The exact number depends on your home, but the mechanism is consistent: less heat in the attic means less heat in your ducts and less heat pressing through your ceiling.
In most cases, blowing on top is the right call. The existing material, even compacted, still provides some R-value, and adding R-30 to R-38 on top gets you where you need to be at a lower cost than full removal. Full replacement makes sense when the old material is wet, rodent-damaged, or contaminated. We’ll tell you which one applies to your specific attic after we inspect it, and we’ll put that recommendation in writing with a flat price before you commit.
The flat, open North Texas prairie provides no natural windbreak or tree canopy buffer. Arlington’s dense 1970s through 1990s subdivisions sit on former grassland, so there’s little shade and nothing to slow the wind that pushes hot air and dust into attic vents. Combined with aging soffit and ridge vents that are often partially clogged, Arlington attics routinely exceed 150°F in July and August. That’s a 20 to 30°F higher differential than a well-vented attic in a more treed area.
That storm exposed what Arlington homeowners and contractors already knew: most local homes were built to cooling-load standards only. When temperatures dropped into the single digits for days, attics with compacted R-11 insulation and unsealed penetrations lost heat fast. Demand for air sealing and insulation retrofits jumped after that week and hasn’t slowed. A properly sealed and insulated attic works in both directions: it keeps heat out in August and keeps it in during a hard freeze. If your home struggled that week, call (218) 261-7714 and we’ll tell you what we’d find in your attic.
