Blown-In Insulation in Pflugerville - Same-Day Service, Done Right the First Time

Trusted Blown-In Insulation for Pflugerville Homeowners

At Topside Attic Insulation Pflugerville, we’ve sealed and insulated over 9,000 homes since 2016, and we never blow insulation over an unsealed attic floor. Our crews work across Pflugerville, from the older ranch homes near downtown to the newer builds in Avalon and Sorrento, and we answer calls live at (737) 259-8352 - no voicemail loops.

Call (737) 259-8352

Pflugerville’s combination of hot, humid summers and sudden winter cold snaps puts serious stress on under-insulated attics. We’ve measured blower-door readings as high as 5,800 CFM50 in 1990s-era homes near Heatherwilde Boulevard, where top plates and can-light penetrations were leaking conditioned air directly into the attic space. That’s money disappearing through the ceiling every month. We treat air sealing as a hard prerequisite, not an upsell, and we publish before-and-after blower-door numbers on every job so you can verify the performance change you paid for.

Every job begins with a written price and ends with a Documented Photo Record. Under our 365-Day Done Right Promise, if it’s not done right, we make it right. Call (737) 259-8352 for a free estimate with upfront pricing - no work starts without a written scope in your hands.

What Our Blown-In Insulation Service Includes

Blown-In Cellulose

Blown-in cellulose is ground paper fiber treated with borate fire retardant, packed to a settled density of about 1.5 pounds per cubic foot. It’s the right choice for Pflugerville homeowners who want to reuse an existing insulation bed rather than strip it out, because cellulose fills irregular joist cavities and compresses around wiring and ductwork better than batts. We specify GreenFiber or Owens Corning cellulose depending on your attic conditions, and we always complete air sealing of top plates, can lights, and plumbing penetrations before the blower truck arrives. In a typical 2,400-square-foot home in Pflugerville, we’re looking at four to six hours of installation after sealing is done.

Blown-In Fiberglass

Blown-in fiberglass uses spun glass fibers, lighter than cellulose at roughly 0.5 pounds per cubic foot, which makes it ideal for attics with weight-sensitive truss designs or where we need to achieve high R-values without overloading ceiling drywall. We see this specified frequently in newer Pflugerville construction, and we offer our Blown-In Insulation in Round Rock as well, especially in neighborhoods like Windermere and Blackhawk, where builders left attics with minimal insulation during the 2015-2020 boom years. Our crews use Johns Manville or CertainTeed fiberglass systems, and we calculate the blown depth against your target R-value - R-38 to R-60 for attics in this climate zone - so you’re not guessing whether you got what you paid for.

Dense-Pack Wall Insulation

Dense-pack wall insulation is blown cellulose or fiberglass installed into closed wall cavities at 3.0 to 3.5 pounds per cubic foot, dense enough to resist settling and slow air movement through the stud bay. This matters in Pflugerville’s older homes, particularly the 1970s and 1980s builds in Original Pflugerville and along FM 1825, and we also provide Hutto Blown-In Insulation, where walls were often built with no insulation at all. We drill access holes at stud-bay intervals, fill with a calculated weight of material, and patch with matching siding or interior texture. The blower-door test before and after tells the story: we’ve seen air leakage drop 18-30% on dense-pack jobs where the walls were the weak link in the envelope.

Blown-In Top-Up

A blown-in top-up adds material over existing insulation that has compressed, shifted, or simply never met code in the first place. We don’t top-up blindly. Our crew photographs the existing layer, measures its settled depth, and checks for moisture staining or rodent damage that would make adding new material a mistake. In Pflugerville, we find a lot of under-spec fiberglass batts from the 2000s - R-19 or R-30 in attics that need R-38 minimum - and a top-up to full depth is often the most cost-effective envelope improvement a homeowner can make. We still seal accessible leaks first, even on top-up jobs, because blowing new insulation over a leaky attic floor is something we simply don’t do.

Brands We Service for Blown-In Insulation

We’ve worked with Rockwool mineral wool insulation in Pflugerville homes where fire resistance and sound dampening are priorities, particularly in homes near the SH 130 corridor where traffic noise carries. Rockwool’s blown product handles moisture better than organic fibers, which matters in attics where bathroom vents have been dumping humid air for years. We also specify CertainTeed fiberglass for homeowners who want a manufacturer with deep Texas distribution and consistent batch quality, and we’ve installed Icynene open-cell spray foam in hybrid jobs where blown insulation alone won’t solve the envelope problems. Our material choice is driven by your home’s condition and your performance goals, not by a proprietary product lock-in.

Whether your existing insulation is CertainTeed, Rockwool, or an unbranded builder-grade batt from 2005, we can assess it, match it, or improve on it. We source materials from Owens Corning, Johns Manville, Knauf, and GreenFiber as well, so we’re not pushing one product line because it’s the only one on our truck.

After

Signs You Need Blown-In Insulation Right Now

• Your upstairs rooms run 8-12 degrees hotter than downstairs in July. This isn’t normal. In Pflugerville’s climate, a properly insulated attic should keep the temperature delta between floors under 4 degrees. When we measure attic floor insulation below R-30, or find it compressed to half its labeled thickness, the thermal boundary has failed and your second floor is essentially under a radiant heater.
• Your energy bills spike every August and January despite steady thermostat settings. We’ve pulled utility bills from Pflugerville homeowners showing $340+ summer cooling costs in 2,000-square-foot homes where the attic was the clear culprit. A blower-door test - that pressurization reading showing how much conditioned air you’re losing - typically reveals the attic floor as the largest single leak path.
• You can see floor joists through your attic insulation. Fiberglass batts settle 10-25% over time, and blown cellulose can shift in attics with active HVAC air handlers or poor baffle installation. If the pink or gray material no longer covers the wood, you’re below code and paying for the gap every month.
• Your insulation is stained, flattened, or has rodent trails. Dark spots indicate air leakage - dirty filter fibers where indoor air has been escaping through the attic floor for years. Flattened areas mean someone walked through it during a prior service call and never restored it. Rodent damage requires removal before any new material goes in, and we handle that as part of our insulation removal and replacement service.
• Your home was built between 1995 and 2010 and has never had an insulation upgrade. Texas energy code lagged national standards during this period, and we’ve found R-19 batts in Pflugerville attics that should have R-38 minimum. Builders in fast-growing areas like Wells Branch and Round Rock during the mid-2000s were particularly prone to minimum-code installs that don’t hold up under real Texas summer loads.

Our Blown-In Insulation Process - Step by Step

1. 1
   Schedule and arrival. You call (737) 259-8352 and a live person answers, 24/7. We book a specific arrival window, not a full-day block. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. Wes Okafor or a member of our crew will walk the attic access with you and note any access limitations before we start.
2. 2
   Attic inspection and blower-door baseline. We photograph the existing insulation, measure settled depth, and run a blower-door test to establish your home’s starting air leakage rate in CFM50 - that single number showing how much conditioned air is escaping. We mark moisture stains, can lights, top plates, and duct penetrations for sealing. You get a written scope and a flat price before anyone lifts a tool. Haven Standard Clause 1: no exceptions.
3. 3
   Air sealing before insulation. We seal top plates with fire-rated caulk or foam, box out can lights with rated covers, seal around chimney chases and plumbing vents, and address any duct boots pulling attic air into your HVAC system. This is non-negotiable. We’ve seen contractors in Pflugerville blow cellulose directly over unsealed recessed lights - that’s a fire hazard and a performance failure, and we won’t do it.
4. 4
   Blown-in installation to specified depth and density. Our crew sets up containment, protects your living space, and blows material to the depth calculated for your target R-value. We mark trusses or joists with depth indicators so you can verify the install later. For cellulose, we’re watching for even distribution without voids near eaves or around obstructions. For fiberglass, we’re confirming the lightweight material hasn’t drifted in windy attic conditions.
5. 5
   Final blower-door test, documentation, and walkthrough. We run the blower door again and compare to your baseline. The before-and-after numbers go in your job folder with the Documented Photo Record - every access point, every sealed penetration, every depth marker. You review the written warranty and the 365-Day Done Right Promise with the crew lead before we leave. The price you were quoted is the price you pay.
