Trusted Attic Insulation for Round Rock Homeowners
Most attic insulation jobs in Round Rock run $1,800-$4,500 depending on square footage, insulation type, and whether air sealing is needed first. We’re typically on-site within 24-48 hours and finish most single-day jobs before the crew leaves. Call (737) 259-7528 for a written price before any work starts.
We’ve sealed and insulated more than 9,000 homes since 2016, and we’ve learned that Round Rock’s combination of hard Texas sun, clay-heavy soil that shifts with the seasons, and attic temperatures that hit 140°F in July makes attic work here different from Austin proper or Georgetown. The homes in Old Town Round Rock, Meadows at Chandler Creek, and Paloma Lake each present their own envelope problems. We’ve documented every one with before-and-after blower-door numbers so homeowners see exactly what changed.
Under Haven Standard Clause 1, you get a written price, written scope, and written warranty before anyone lifts a tool. No exceptions. Our technicians are background-checked and uniformed, and a live person answers our phones 24/7. Wes Okafor has led this operation since day one, and the 365-Day Done Right Promise applies to every completed job.
What Our Attic Insulation Service Includes
Blown-In Attic Insulation
Blown-in insulation - loose-fill cellulose or fiberglass blown through a hose to achieve consistent depth and coverage - is what most Round Rock attics need when the existing material has settled below R-38 or never reached it in the first place. We see this constantly in 1990s-era subdivisions like Behrens Ranch and Greenlawn Crossing, where original fiberglass batts have compressed to half their labeled thickness. Our crew runs a blower-door test first, seals top plates and penetrations, then blows Knauf Jet Stream Ultra or Johns Manville Climate Pro to the depth specified in your written scope. You get photos of the attic before, during air sealing, and after the final blow.
Attic Batt Insulation
Batt insulation - pre-cut fiberglass or mineral wool panels fitted between joists - makes sense when we’re working in confined attic spaces where blown-in would drift into soffits, or when a homeowner needs targeted spot repair after rodent damage or water intrusion. In Round Rock’s newer builds, particularly in Forest Creek and Siena, we often find batt insulation installed without proper ventilation baffles, creating moisture traps against the roof deck. We remove compromised batts, install baffles where needed, and fit new Rockwool Comfortbatt or CertainTeed fiberglass to the joist bays. Every cut is photographed; the scope notes which bays were treated and why.
Attic Insulation Top-Up
An attic insulation top-up adds material over existing insulation that is in decent shape but no longer meets current energy code or the homeowner’s comfort goals. This is common in Round Rock homes built between 2005 and 2015, where original R-30 fiberglass has settled to R-22 or below. We don’t top up over wet, moldy, or rodent-contaminated material - that’s replacement, not top-up - and we’ll show you the photos that prove which category your attic falls into. When conditions allow, we blow new Johns Manville or GreenFiber cellulose over the existing layer, bringing the total assembly to R-49 or R-60 per your written scope. The blower-door test before and after shows whether the air sealing we performed actually reduced infiltration, or if we need to chase more leaks.
Attic Insulation Replacement
Full replacement means removing all existing insulation, remediating whatever caused it to fail, and installing new material from a clean substrate. We do this when insulation has been compromised by roof leaks, raccoon or squirrel activity, or decades of dust and organic loading that no longer performs. In Round Rock neighborhoods like Cat Hollow and Round Rock West, we’ve pulled out insulation that predates the city’s 2000 building code updates and found unsealed can lights, open chase ways, and top plates leaking conditioned air directly into the attic. Replacement includes full removal, HEPA vacuuming of the deck, air sealing of every penetration, and new insulation to spec. The photo record documents the empty deck, the sealed penetrations, and the finished installation.
Attic Baffles & Ventilation Prep
Attic baffles - also called rafter vents or vent chutes - are rigid foam or cardboard channels that maintain airflow from soffit vents up along the underside of the roof deck, preventing insulation from blocking intake ventilation. Without them, Round Rock’s intense attic heat builds moisture that warps roof sheathing and degrades shingle life. We install baffles before any new insulation goes in, ensuring a clear path from soffit to ridge vent. In homes with complex rooflines, like those in Teravista or Walsh Ranch, we map the ventilation strategy and photograph each baffle location so the homeowner and any future inspector can verify the work. This step is non-negotiable under our protocol; we will not insulate an attic without confirming the ventilation path.

Brands We Service for Attic Insulation
We source and install materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in means we specify what’s right for your attic, not what a manufacturer requires us to move. We’ve run thousands of bags of Knauf Jet Stream Ultra through our blowers, and we know its settling characteristics in Round Rock’s humidity. Rockwool Comfortbatt is our go-to for fire-resistant mineral wool applications, particularly in homes with wood stove or fireplace penetrations where non-combustible clearance matters. CertainTeed’s fiberglass products integrate cleanly with their moisture-resistant facing options when we’re working in attics with known historical leakage.
Whether your existing insulation is Johns Manville from a 2012 build, Rockwool from a custom home in Brushy Creek, or an unbranded commodity product a previous installer sourced, we can assess its condition, match or improve its performance, and document the change. We don’t claim exclusive status with any manufacturer; we claim competence with all of them.
Signs You Need Attic Insulation Right Now
- Your upstairs rooms are 8-12 degrees hotter than downstairs in July. This isn’t normal HVAC imbalance. In Round Rock, where attic temperatures routinely exceed 130°F, inadequate or settled insulation lets that heat radiate through the ceiling plane, overwhelming your air conditioner’s capacity to maintain setpoint. We’ve measured ceiling surface temperatures of 95°F in poorly insulated second-floor rooms while the thermostat reads 74°F.
- Your energy bills spike every summer despite no change in thermostat setting. When conditioned air leaks into the attic through unsealed top plates and the attic dumps heat back through thin insulation, your system runs longer cycles to compensate. A blower-door test quantifies this; we regularly see Round Rock homes losing 25-40% of conditioned air to attic bypasses before we seal them.
- You can see floor joists through your existing attic insulation. Fiberglass batts settle; blown cellulose compresses from foot traffic and moisture cycling. If the pink or gray material no longer covers the tops of joists, you’re below code minimum and likely below the R-value your home was originally built to. We photograph this during inspection and measure depth with a ruled probe.
- Ice dams formed on your roof during the February 2021 freeze or subsequent winter events. Ice dams occur when attic heat melts snow from below; water runs to the cold eave and refreezes. They’re rare in Central Texas, but when they happen, they point to severe attic air leakage and inadequate insulation. The same bypasses that cause summer heat gain cause winter heat loss.
- Your insulation is stained, compacted, or has visible rodent trails. Dark stains indicate air leakage filtering dust through the material; compaction means moisture or physical damage has destroyed loft. Rodent activity introduces biohazard and compresses insulation into useless mats. Neither condition responds to top-up; replacement with remediation is the only defensible approach.
Our Attic Insulation Process - Step by Step
- 1
Schedule and arrival. You call (737) 259-7528 and speak to a live person. We book a window, text you when the technician is en route, and arrive in a marked vehicle with a uniformed, background-checked crew. Under Haven Standard: Arrive on schedule, you get a named technician.
- 2
Attic inspection and blower-door test. We enter the attic with full PPE, document existing conditions with dated photos, and run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. In Round Rock, a typical pre-sealing reading is 3,500-5,500 CFM50 for a 2,000-square-foot home. We mark every penetration, top plate gap, and can light with fluorescent tags for the photo record.
- 3
Written scope and price. Before any work begins, you receive a written scope specifying insulation type, target R-value, air-sealing details, and flat price. Haven Standard Clause 1: no work starts without it. If you have a competing estimate, bring it; we offer a Free Second Opinion and will read it with you line by line.
- 4
Air sealing first, then insulation. We seal every marked penetration with fire-rated caulk, foam, or rigid blocking as appropriate. Can lights get airtight covers. Chase ways get boxed and sealed. Only after the blower-door test shows meaningful reduction do we begin insulation installation. This sequence is non-negotiable; we have never blown insulation over an unsealed attic floor and we never will.
- 5
Final blower-door test, photo record, and documentation. After installation, we run the blower-door test again and publish both numbers on your job record. You receive a Documented Photo Record of the entire process, a written warranty, and the 365-Day Done Right Promise. If the final reading doesn’t meet the target we set in your scope, we find the leak and fix it before we leave.
How Much Does Attic Insulation Cost in Round Rock?
A typical attic insulation top-up in a 1,800-2,400 square foot Round Rock home runs $1,800-$2,800. Full replacement with air sealing in the same footprint usually falls between $3,200-$4,500. Batt installation in a partial attic or targeted repair starts around $1,200. These ranges reflect 2024-2025 material and labor costs in the Austin-Round Rock MSA; your written price may fall above or below depending on what we find.
Several factors move the number. Attic accessibility matters - a scuttle hatch in a closet costs more in labor than a pull-down stairs in a hallway. The condition of existing insulation determines whether we can top up or must remove and replace. Air sealing extent varies; a 1980s home in Jollyville with dozens of unsealed can lights requires more prep than a 2018 build in Paloma Lake with a relatively tight envelope. Material choice affects price too - Rockwool mineral wool runs higher per square foot than fiberglass, and spray foam applications fall outside these ranges entirely.
What’s included in our free estimate: attic inspection, blower-door test, thermal imaging if indicated, written scope with flat price, and no obligation to proceed. We don’t quote over the phone based on square footage alone; the inspection is how we find the problems that actually drive cost and performance. Call (737) 259-7528 to schedule - estimates are free, and you’ll have the written price before anyone starts.

Frequently Asked Questions - Attic Insulation in Round Rock
Attic insulation is a thermal barrier - typically fiberglass, cellulose, or mineral wool - installed between your conditioned living space and the unconditioned attic above, slowing heat transfer so your HVAC system doesn’t work as hard. In Round Rock, where summer attic temperatures exceed 130°F and winter overnight lows occasionally drop below 20°F, adequate insulation is the single most cost-effective envelope upgrade for year-round comfort and predictable energy bills. Most homes built before 2015 fall short of current IECC code minimums of R-38 to R-49.
Most attic insulation jobs are completed in one day, with air sealing in the morning and insulation installation in the afternoon. Full replacement with removal and remediation may extend to a second day for larger homes or complex attic configurations. We don’t rush the blower-door verification; if the post-sealing numbers aren’t where they need to be, we stay until they are. You’ll know the expected duration when you receive your written scope.
Attic insulation in Round Rock typically costs $1,800-$4,500 depending on whether you’re topping up existing material or replacing it entirely, the square footage of your attic floor, and the extent of air sealing required. We publish these ranges because Haven Standard Clause 1 requires a written price before work starts, and we don’t ask homeowners to call blindly. Your specific price comes after inspection, not before. Call (737) 259-7528 for a free estimate - there’s no obligation, and you’ll have the number in writing.
Yes. We install and replace insulation from all four brands, plus Owens Corning, GreenFiber, Icynene, and Demilec. We don’t carry proprietary product lines that lock us into a single manufacturer; we specify based on your attic’s conditions, fire-safety requirements, and performance goals. If your existing insulation is one of these brands, we can assess its condition and match or upgrade it with the same or compatible material.
We answer calls 24/7 and can usually schedule an estimate same-day or next-day for Round Rock proper. True emergencies in attic insulation are rare - a roof leak actively wetting insulation, or a raccoon infestation with live animals - but we treat them with priority response. For standard comfort and efficiency concerns, our typical lead time is 24-48 hours for estimate, 3-7 days for installation after scope approval. Call (737) 259-7528 and a live person will find the next available slot.
Every job is backed by our 365-Day Done Right Promise - if it’s not done right, we make it right - plus the written warranty delivered before work starts under Haven Standard Clause 1. The warranty covers material and workmanship defects, and the blower-door numbers we publish give you an objective benchmark to verify performance. If your attic doesn’t perform as specified in the scope within the first year, we return and correct it at no charge.
Clear a path to your attic access and remove any stored items you need from the attic floor before we arrive; our crew will handle everything else. If you have pets, secure them in a separate room during the blower-door test, which depressurizes the house and can startle animals. We bring drop cloths, HEPA vacuums, and full containment as needed. You’ll receive a text when we’re en route and a photo record when we leave. No special preparation is required beyond access and clear communication about any known roof leaks or electrical concerns in the attic.
