Trusted Attic Insulation for New Braunfels Homeowners
Attic insulation in New Braunfels typically runs $2,400-$5,800 for a full replacement in a 2,000-square-foot home, and most jobs are completed in a single day. At Topside Attic Insulation New Braunfels, we’ve sealed and insulated more than 9,000 homes since 2016, and every one started with a written price before any work began. If your upstairs rooms won’t cool below 78 degrees in July, your energy bills spike every August, or your insulation looks flattened or disturbed, you’re losing conditioned air through a leaky thermal envelope. We answer calls live 24/7 at (830) 243-6352, and we can usually inspect your attic within 24 hours.
New Braunfels sits in Comal and Guadalupe counties where summer attic temperatures regularly hit 140°F and winter cold fronts drop below freezing. That temperature swing pushes air through gaps in top plates, can lights, and duct chases that most homeowners never see. We treat air sealing as a hard prerequisite, not an upsell. Before we blow a single bag of insulation, we seal every penetration we can access. Then we document the work with before-and-after blower-door numbers so you can verify the performance change in writing.
What Our Attic Insulation Service Includes
Blown-In Attic Insulation
Blown-in insulation, also called loose-fill, is cellulose or fiberglass material blown through a hose to create a continuous thermal blanket across your attic floor. In New Braunfels, we install blown-in insulation most often in homes built between 1980 and 2010 where original fiberglass batts have compressed below their labeled R-value. Our crews use depth markers and rulers to verify uniform coverage, and we calculate the exact bag count needed to hit your target R-value based on the Department of Energy’s climate zone 2 recommendations. Every blown-in job includes sealed top plates and protected soffit vents before the material goes in.
Attic Batt Insulation
Batt insulation comes in pre-cut fiberglass or mineral wool panels sized to fit between standard joist spacing. We recommend Attic Batt Insulation in New Braunfels when we’re insulating a finished attic space, a knee wall, or any area where we need clean edges and precise cuts around framing obstacles. Our technicians cut each piece to fit tightly around electrical boxes and duct boots, compression gaps that destroy R-value. We source batts from Owens Corning and Johns Manville in thicknesses from R-13 to R-38, and we staple insulation supports to keep batts in full contact with the air barrier below.
Attic Insulation Top-Up
An Attic Insulation Top-Up adds new insulation over existing material that is still in reasonable condition but has settled below effective depth. In neighborhoods like River Chase and Copper Ridge, we see original R-30 fiberglass that has compressed to R-19 or lower after 15-20 years. We don’t top-up over water-stained, rodent-contaminated, or mold-affected insulation. First we remove the compromised layer, seal the air leaks that caused the problem, then install the new material. A typical top-up in New Braunfels adds R-19 to R-30 over existing batts or loose fill, and most homes qualify if the original insulation was installed after 2000 and shows no moisture damage.
Attic Insulation Replacement
Attic Insulation Replacement means removing all existing insulation, remediating any underlying issues, and installing new material to current code. We recommend this for New Braunfels homes with pre-1990 insulation, evidence of rodent activity, or multiple roof leaks that have saturated the attic floor. Our crew vacuums out old material with HEPA-filtered equipment, treats the deck for organic growth if needed, installs baffles at every eave, seals all accessible penetrations, and then blows new insulation to the specified depth. You receive a Documented Photo Record of the empty attic, the sealed deck, and the finished installation, plus blower-door numbers if air sealing is part of the scope.
Attic Baffles & Ventilation Prep
Attic Baffles & Ventilation Prep involves installing rafter vents, channels that maintain airflow from soffit vents up to ridge vents, preventing new insulation from blocking the intake. In New Braunfels, where humid Gulf air meets Hill Country temperature swings, blocked soffits create moisture problems that show up as stained drywall or mold on roof sheathing. We install rigid polystyrene or cardboard baffles at every bay, extending from the eave past the expected insulation height. This step is non-negotiable on every job we do. Without it, you’re paying for insulation that will underperform and potentially trap moisture against your roof deck.

Brands We Service for Attic Insulation
We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, with no proprietary product lock-in that limits your options. Owens Corning’s blown fiberglass and batts are what we specify most often for standard attic floors in New Braunfels, their AttiCat system installs cleanly and the pink fiberglass doesn’t settle the way cellulose can over decades in high-heat attics. We’ve also completed dozens of jobs with Johns Manville formaldehyde-free batts for homeowners with chemical sensitivities, their mineral wool handles the 140°F summer peak without binder degradation.
Demilec’s open-cell spray foam comes into play when we’re sealing a conditioned attic or insulating against roof decking in a home with HVAC equipment in the attic space. GreenFiber cellulose is our choice when homeowners want a recycled-content material with good air-sealing properties at blown density. Whether your existing insulation is Owens Corning, Johns Manville, or any other make, we can assess its condition, match or upgrade the material, and document the performance change.
Before
AfterSigns You Need Attic Insulation Right Now
- Your upstairs rooms stay 8-15 degrees hotter than downstairs in summer. This temperature stratification means your conditioned air is leaking into the attic faster than your HVAC can replace it. In New Braunfels, we see this most in two-story homes in Vintage Oaks and Oak Run where the duct chase and top plate gaps act like chimneys pulling cool air upward.
- Your energy bill jumps $80-$150 every July and August compared to spring months. Spiking cooling costs are often the first measurable symptom of attic heat gain overwhelming your insulation’s effective R-value. If your bill pattern changed suddenly, you may also have a disconnected duct in the attic pulling 130°F air directly into your system.
- You can see floor joists through your attic insulation. Original insulation depth should cover joists completely, batts or loose-fill that has compressed or been disturbed by rodents no longer provides the labeled thermal resistance. In homes near the Guadalupe River, we’ve also found that high humidity accelerates fiberglass compression over time.
- You feel drafts near outlets, switches, or baseboards on exterior walls. These are the telltale signs of unsealed top plates, the horizontal framing member where your wall meets your ceiling. Air moves through these gaps into wall cavities and out at every penetration. Insulation alone won’t stop it, sealing first will.
- Your roof sheathing shows dark staining or frost in winter. This indicates warm, moist interior air reaching cold surfaces, a combination of air leakage and inadequate insulation that leads to mold and sheathing rot. In New Braunfels, this pattern shows up after cold fronts when attic ventilation can’t keep pace with the moisture load.
Our Attic Insulation Process - Step by Step
- 1
Scheduled arrival with text notification. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. Our technician arrives in a marked vehicle, introduces themselves, and lays protective covering from the entry point to the attic access. We inspect the access itself for proper weatherstripping and insulation, a detail most crews skip that costs you R-value at the hatch.
- 2
Attic inspection and photo documentation. We photograph existing insulation depth, condition, and any problem areas like water staining, rodent evidence, or disconnected ducts. We measure the attic floor area, count ventilation openings, and locate every penetration through the ceiling plane. This documentation becomes your baseline record.
- 3
Blower-door test (when air sealing is in scope). We run a blower-door test, a pressurization reading that shows, in one number, how much air your building envelope is losing. Typical pre-sealing numbers in New Braunfels range from 3,500 to 6,000 CFM50 depending on home age and size. This gives us a target and gives you a verified metric for the work.
- 4
Air sealing before insulation. We seal top plates with polyurethane foam, caulk around electrical boxes and pipe penetrations, install fire-rated covers over can lights, and seal duct boots and chases. In New Braunfels, the gap around chimney chases and plumbing vent stacks are usually the largest single leaks we find in homes built before 2005.
- 5
Insulation installation with depth verification and final documentation. We install baffles, blow or place insulation to specified depth, verify with rulers at multiple points, and photograph the completed work. On air-sealing jobs, we run a second blower-door test and publish the before-and-after numbers on your invoice. You receive the written scope, the photo record, and the performance data before we leave.
How Much Does Attic Insulation Cost in New Braunfels?
Most attic insulation jobs in New Braunfels run between these ranges:
| Service | Typical Range | What Affects Price |
|---|---|---|
| Attic insulation top-up (add R-19 to R-30) | $1,800 - $3,200 | Attic square footage, access difficulty, need for baffles |
| Blown-in attic insulation, full install | $2,400 - $4,500 | Target R-value, air sealing extent, existing removal needed |
| Attic batt insulation, finished spaces | $2,800 - $5,200 | Material type, labor intensity of cuts, obstructions |
| Full insulation replacement with removal | $3,500 - $6,800 | Contamination level, deck treatment, ventilation corrections |
| Air sealing only (before insulation) | $800 - $1,800 | Home size, accessibility, number of penetrations |
These are the factors that move your price within those ranges. Attic square footage is the largest variable, a 1,200-square-foot attic costs substantially less than 2,500 square feet. Access difficulty matters too, scuttle holes in closets add labor compared to full-size pull-down stairs. If we need to remove contaminated insulation, that adds HEPA vacuuming and disposal fees. The condition of your existing ventilation, whether soffit vents are blocked or ridge vents are missing, can require baffle installation or vent additions.
How to avoid overpaying: get a written scope that specifies the R-value you’re paying for, the material type and brand, and whether air sealing is included or priced separately. A quote that only says “insulate attic” without these details leaves room for corners to be cut.

We also offer a Free Second Opinion on any written estimate, bring us a competing quote and we’ll read it with you to compare scope and materials.

Frequently Asked Questions - Attic Insulation in New Braunfels
Attic insulation is a thermal barrier that slows heat transfer between your conditioned living space and the unconditioned attic above. In New Braunfels, where attic temperatures reach 140°F in summer and cold fronts drop below freezing in winter, adequate insulation reduces the load on your HVAC system and keeps indoor temperatures stable. Most homes built before 2012 are underinsulated by current Department of Energy standards for climate zone 2. Call (830) 243-6352 for a free assessment of your current R-value.
Most attic insulation jobs in New Braunfels are completed in one day, typically 4 to 8 hours depending on attic size and whether removal or air sealing is included.
