Fast, Reliable Attic Insulation Across Flower Mound
If your Flower Mound home has a bonus room over the garage that’s 10 to 15 degrees hotter than the rest of the upstairs, the answer isn’t a bigger air conditioner. It’s the garage ceiling. Most homes built in Flower Mound between the late 1980s and mid 2000s have no insulation there at all, or a few inches of compressed batt that does nothing against a July attic that hits 140°F. We fix that. Topside Attic Insulation air-seals first, then insulates, and we publish before-and-after blower-door numbers on every job. Call (218) 261-7714 for a written price before any work starts.
We’re the only Attic Insulation contractor in North Texas that treats air sealing as a prerequisite, not an upsell. That matters in Flower Mound, where builder-grade fiberglass has settled and underperformed for two decades. Under The Haven Standard, every job starts with a written scope and a written price. It ends with a Documented Photo Record and, on applicable work, blower-door readings you can read yourself.
Why Topside Attic Insulation Is Flower Mound’s Preferred Attic Insulation Company
Wes Okafor founded Topside Attic Insulation in 2016 with a simple rule: nobody blows insulation over an unsealed attic floor. That’s the whole company. Our crews work in Flower Mound weekly, across Wellington, Bridlewood, The Sanctuary, and the subdivisions along Morriss Road and FM 1171. We know what the 1990s McMansion-era builders put up there, because we’ve measured it. R-19 to R-30 blown fiberglass, settled to half its label depth in some homes.
What Flower Mound customers get from us is documentation, not a sales pitch. A blower-door test, which is a pressurization measurement showing in one number how much conditioned air your home is losing, before we start and after we finish. A written price before anyone lifts a tool, per Haven Standard Clause 1. A named technician and a text when he’s on the way. And background-checked, uniformed crews who answer to Wes directly. No voicemail loops.
Since 2016, we’ve sealed and insulated 9,000+ homes across the DFW metro, every one with a written record. The 365-Day Done Right Promise backs every job: if it’s not done right, we make it right, in writing, before you sign anything.
Our Attic Insulation Services in Flower Mound
Attic Insulation Top-Up
Most Flower Mound homes built before 2005 sit at R-19 to R-30. Today’s recommendation for North Texas Climate Zone 3 is R-49. A top-up adds blown insulation over your existing layer, after we air-seal the top plates, can lights, and penetrations that have been leaking conditioned air into your attic for 20 years. In Flower Mound, where summer attic temperatures exceed 140°F, that jump from R-30 to R-49 is the difference between an upstairs that cools and one that runs the AC from June through September without stopping. Typical top-up work for a 3,000 sq ft Flower Mound home runs $2,200 to $4,600, depending on current depth and the air-sealing scope.
Attic Batt Insulation
Batts go where blown insulation can’t: the garage ceiling below that bonus room, knee walls, and sloped ceiling cavities. We stock Owens Corning EcoTouch and Knauf EcoBatt in our DFW warehouse, so Flower Mound jobs don’t wait on special orders. The failure we see most in Flower Mound’s master-planned subdivisions is a garage ceiling with nothing above it, or 2 to 3 inches of compressed R-11 that’s doing approximately nothing. Batt insulation, properly installed with a vapor-tight fit and no gaps, restores the thermal boundary between your garage and the living space above it.
Blown-In Attic Insulation
Blown fiberglass remains the most cost-effective way to bring a large Flower Mound attic to R-49. We use CertainTeed InsulSafe and Owens Corning AttiCat, blown to the full labeled depth, never fluffed to look thicker than it is. Our crews level it to spec and document the final depth in your photo record. For a 2,500 to 4,500 sq ft Flower Mound home that’s never been topped up, full blown-in coverage typically runs $3,100 to $6,800 with air sealing included. That’s a written price, not an estimate that changes after we start.
Attic Insulation Replacement
If your Flower Mound attic has been through a roof leak, a rodent infestation, or a contractor who blew insulation right over active electrical issues, removal and replacement is the right call. We remove the old material, inspect the attic floor and wiring, air-seal, and install fresh insulation to R-49. We also handle the attic cleaning and rodent proofing that often precedes replacement in Flower Mound’s older subdivisions, where the original construction left gaps around soffit intersections and pipe chases. Replacement work on a 3,000 sq ft home generally runs $4,800 to $9,200, including removal, disposal, air sealing, and new blown insulation.
Attic Baffles & Ventilation Prep
Air sealing without ventilation creates problems, and ventilation without air sealing just sucks conditioned air out of your house. In Flower Mound, where the attic bakes all summer, soffit baffles keep the air path from your eaves to your ridge open or, if you have a ridge vent, ensure it’s actually functioning. Flower Mound’s large mid-1990s homes frequently have soffit vents blocked by over-blown insulation or painted-over vents. We install baffles in every rafter bay where ventilation is needed, then document what the airflow looks like after. Baffle and ventilation prep on a typical two-story Flower Mound home runs $600 to $1,400.

Trusted Brands We Service in Flower Mound
We are not married to one manufacturer, so we’re not tempted to sell you a product you don’t need. On Flower Mound jobs we install materials sourced from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Denilec, and GreenFiber. What we put in your attic is what the scope says, not what the warehouse happened to have on sale. If your Flower Mound home has a specific material requirement from a builder or architect, we can source it. No proprietary lock-in, and no product we wouldn’t put in our own attics.
Common Attic Insulation Problems We See in Flower Mound Homes
- Bonus room above the garage has no thermal barrier. The garage ceiling in Flower Mound’s 1990s and early 2000s subdivisions often has nothing between the garage and the living space above. The floor radiates heat all summer and cold all winter.
- Builder-grade blown fiberglass settled to R-19 or R-30. Most Flower Mound homes built before 2005 came with insulation that met the minimum code of that era. Today’s R-49 recommendation means nearly the entire housing stock is an upgrade candidate.
- Uninsulated pipe chases in exterior walls. During Winter Storm Uri in February 2021, thousands of Flower Mound homes had pipes burst in exterior wall cavities and attic chases where insulation was thin or missing. We see the same failure points on nearly every pre-2010 job.
- Attic air leaks depressurize the whole house. Can lights, top plates, and plumbing penetrations leak conditioned air into a 140°F attic all summer. Insulating over those leaks just hides them. Sealing first is the entire reason Topside exists.

FAQs - Attic Insulation in Flower Mound
Because the garage ceiling below that room has little or no insulation, and heat from the 140°F attic and hot garage slab radiates directly through the floor. In a Flower Mound home built in the 1990s or early 2000s, the garage ceiling often has no insulation, or 2 to 3 inches of compressed R-11 batt that’s effectively useless. We fix this by air-sealing the rim joists, installing R-38 batts, and adding soffit baffles. At a home in Wellington of Flower Mound, our crew found the bonus room at 88°F in late afternoon while the rest of the upstairs held at 74°F. After sealing and insulating the garage ceiling, the bonus room stabilized within 2 degrees of the adjacent bedrooms. Call (218) 261-7714 if this sounds like your house.
Yes, in nearly every case. Flower Mound homes from that era were insulated to pre-IECC standards, commonly R-19 to R-30 blown fiberglass that has likely settled below its label depth. North Texas Climate Zone 3 calls for R-49 today. The gap between R-30 and R-49 means your air conditioner is working against heat gain it was never sized for. A top-up over existing insulation, after air sealing, is the single most cost-effective upgrade for a Flower Mound homeowner. Pricing for a top-up on a 3,000 sq ft home typically falls between $2,200 and $4,600, sealed first.
Flower Mound’s builder-era homes had thin or missing insulation in exterior wall pipe chases and attic chases. When temperatures dropped and stayed below freezing, pipes in those uninsulated cavities froze and burst. The failure was widespread across the master-planned communities because the construction was uniform: same builders, same shortcuts, same result. We insulate those chases and the adjacent wall cavities as part of our air-sealing scope, before any attic insulation goes in. It’s not an upsell; it’s the work we’re there to do.
No. Adding insulation or air sealing does not void a builder’s structural warranty, and in Flower Mound’s newer subdivisions built after 2015, upgrading to R-49 is often needed to hit the performance the builder promised but the original insulation doesn’t deliver. Federal and Texas energy-efficiency standards have moved significantly since many of these homes were framed. That said, if you have a written warranty, bring it to your estimate. Wes Okafor will read it with you and tell you exactly what’s Covered, what’s excluded, and what your insulation work changes, in plain English.
Two quick checks. First, look at the depth: if you can see the tops of your ceiling joists, you’re under-insulated. Second, note when your upstairs stops cooling in the afternoon: if the AC runs continuously from June through September and the top floor still sits at 78°F or above, your attic insulation is failing. The definitive test is the blower-door reading we run on every applicable job. A Flower Mound home losing 4,200 CFM50 has an envelope problem; after sealing and insulation, that number typically drops by half or more, and we give you the before and after in writing. Call (218) 261-7714 for a documented assessment of your attic.
