We’ve worked on enough homes off Broadway, in the Ogden and Tuxedo neighborhoods, and around the Alamo Heights Independent School District to know the pattern: a 1930s brick Tudor or Spanish Eclectic with plaster-over-lath walls, little or no original wall insulation, and an attic that hits 150°F by mid-July. The retrofit challenge here isn’t the same as slapping batts into a 2015 suburban tract. Our Attic Insulation team treats air sealing as a hard prerequisite, not an upsell, and we pull Alamo Heights city permits for every job that requires one.

Why Topside Attic Insulation New Braunfels Is Alamo Heights’s Preferred Attic Insulation Company

We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of those have been in Alamo Heights and the near-inner suburbs. Our Alamo Heights customers leave reviews that mention the same things: the written price that showed up before anyone touched a tool, the blower-door numbers they could compare, and the photo record they received when the crew left. We don’t ask you to trust us because we’ve been around a while. We ask you to read the documentation we hand you.

Response time to Alamo Heights is typically same-day or next-day for estimates, and we answer calls 24/7 with a live person. No voicemail loops. No “we’ll call you back Tuesday.”

What matters locally is permit fluency. Alamo Heights is an independent municipality entirely surrounded by San Antonio with its own building department. We’ve seen contractors assume a San Antonio permit covers the job and stall the install for weeks. We don’t. We pull Alamo Heights permits, not San Antonio permits, even when the house sits one block from the city boundary. That local knowledge saves you time and keeps your job moving.

Our Attic Insulation Services in Alamo Heights

Blown-In Attic Insulation

Blown-in fiberglass or cellulose is our most common install in Alamo Heights, especially for the compartmentalized attic bays in 1920s-1950s homes where batts won’t sit evenly. We use Owens Corning and Johns Manville loose-fill products, blown to consistent depth with marked rulers visible across the attic floor. Before we blow anything, we seal top plates, can lights, and penetrations. In Alamo Heights, we regularly find original knob-and-tube wiring in these attic spaces; we shield or flag it per code before insulation covers it. Blowing over unshielded knob-and-tube is a hazard we won’t perform.

Attic Batt Insulation

Batt insulation works in Alamo Heights when the attic geometry cooperates: newer additions, dormers, or areas with clear joist bays and adequate headroom. We stock Knauf and Rockwool batts for jobs where the homeowner wants the density and fire resistance of mineral wool. Even with batts, we air-seal first. A batt laid over a leaky attic floor is a filter, not a thermal barrier.

Attic Insulation Top-Up

Many Alamo Heights homes have some existing insulation - usually degraded early fiberglass batts settled to R-11 or R-19, well below the R-38 to R-60 recommended for south-central Texas. A top-up runs $900-$1,800 in Alamo Heights, depending on attic square footage and access difficulty. We remove the worst of the settled material, air-seal what the original crew missed, then blow new insulation over the cleaned substrate. On a 1930s Tudor Revival off Ogden, our crew ran into compartmentalized attic bays sealed by original plaster-over-lath and a 150°F late-July attic heat load; we pulled the Alamo Heights city permit first, shielded the knob-and-tube runs, then blew Owens Corning blown-in to a level top-up over the degraded early fiberglass batts. The homeowner kept every original finish in place and the attic dropped roughly 30°F on the next hot afternoon.

Attic Insulation Replacement

Full replacement is the right call when existing insulation is contaminated, water-damaged, or installed over an unsealed attic floor that needs to be opened up. In Alamo Heights’s older housing stock, we often find batts compressed by decades of storage traffic, rodent activity, or prior HVAC work. We remove the old material, perform full air sealing, install baffles at every eave for ventilation continuity, then blow new insulation to a uniform depth. Typical range in Alamo Heights: $2,400-$4,200 for a full replacement on a 1,800-2,800 square foot home.

Attic Baffles & Ventilation Prep

Compartmentalized tight attic bays along Broadway and in the Ogden/Tuxedo neighborhood trap heat and moisture if you seal them without baffles. We install rigid foam or cardboard baffles at every soffit vent before insulation goes in, maintaining the ventilation channel that keeps the roof deck dry and the historic plaster-over-lath assembly intact. This step is non-negotiable on our Alamo Heights jobs. Skip it, and you’re trapping 150°F air against surfaces that were never designed for it.

Common Attic Insulation Problems We See in Alamo Heights Homes

• Knob-and-tube wiring in original attic spaces. Homes built before 1950 in Alamo Heights frequently have active or abandoned knob-and-tube runs across the attic floor. Blowing insulation over these without proper shielding or evaluation is a code violation and a fire risk. We identify, shield, or flag every run before adding material.
• Degraded early fiberglass batts settled to half their original R-value. The pink batts installed in the 1970s or 1980s have compressed, torn, or displaced over decades of attic traffic. They read as “insulated” on a casual inspection but perform like open air. We measure what’s there and show you the numbers.
• Zero wall cavity insulation in brick homes along Broadway and Ogden. Many older two-story brick homes have no wall insulation whatsoever - just brick veneer tied to wood sheathing over lath and plaster. Dense-pack blown-in through small exterior drill holes is often the only retrofit option that preserves the historic interior finishes Alamo Heights homeowners strongly resist disturbing.
• Assuming a San Antonio permit covers the job. Alamo Heights has its own building department and permit process. We’ve seen projects stall for weeks when a contractor discovers this mid-job. We pull the correct permit from the start.
