Most jobs finish in a day. If your second floor runs ten degrees hotter than the rest of the house, or your energy bills jump every July, the attic is almost always the culprit. We work throughout Highland Park weekly, from the estates off Preston Road to the tree-lined blocks near Armstrong Parkway, and we know exactly what these older homes need.

Why Aspen Attic Insulation Dallas Is Highland Park’s Preferred Attic Insulation Company
Highland Park homes are not like the rest of Dallas. They’re older, they’re built differently, and they’re often subject to preservation rules that a generic insulation crew won’t know about. Our Attic Insulation team has spent years working inside 1920s and 1930s masonry homes here, which means we walk in already knowing what we’ll find: shallow rafter bays, knob-and-tube wiring, slate or tile roofs with no ridge vents, and original framing you don’t want to disturb.
Every technician who arrives at a Highland Park address is background-checked, identity-verified, and photo-badged under what we call the Threshold Standard. You get the tech’s name and photo before the visit. If someone else shows up, the visit is free and we make it right. That’s not a marketing line; it’s the operating rule.
We answer the phone 24/7 with a live person. When you call about a hot upstairs or an attic full of old fiberglass, you’re talking to someone who can schedule a look and give you a written price before any work starts. No post-job surprises, ever.
Radiant Barrier in Highland Park
Radiant barrier in Highland Park is a particularly good fit for homes with original slate or clay tile roofs because it reflects heat before it ever reaches the attic floor, without requiring roof modifications that preservation codes reject. Attaching a foil-faced barrier to the underside of the rafters in a 1930s masonry home can cut attic temperatures by 20 to 30 degrees on an August afternoon. In Highland Park, a typical radiant barrier installation runs $1,800 to $3,900 depending on attic square footage and rafter configuration.
This is the fastest way to reduce cooling load in a historic home where the roof cannot be touched. The barrier works independently of insulation depth, so it pairs well with a blown-in top-up if your attic already has old, settled material you don’t want to remove.
Foil-Faced Attic Decking
For attics with open rafter bays, we staple a double-sided foil laminate directly under the roof deck. This cuts radiant heat transfer by up to 97 percent on the surface itself. It also keeps the attic cooler for whatever insulation sits below.
Radiant Barrier Retrofit
If your Highland Park attic already has decking or storage flooring, we can install the barrier on the gable ends and around the access hatch, which reduces heat gain where it concentrates. This is a smaller job, typically $800 to $1,500, and it makes a measurable difference in older attics with poor cross-ventilation.
Attic Cleaning Services in Highland Park
Attic cleaning services in Highland Park are frequently the first step before any insulation work, simply because decades of dust, pest debris, and crumbling old fiberglass make a proper air-seal impossible. Homes along Beverly Drive and Lakeside Drive are notorious for attics that haven’t been touched since the Eisenhower administration. A full attic cleaning in Highland Park, including old insulation removal, HEPA vacuuming, and disinfecting, typically runs $1,200 to $2,800 depending on attic size and debris level.
We always clean before we insulate. Blowing new cellulose over old rodent droppings or deteriorated batts doesn’t solve anything. It just buries the problem under a fresh layer.
Old Insulation Removal
When original fiberglass batts have compressed to an inch of slumping material, they’re doing nothing. We pull everything out, vacuum the decking, and give you a clean substrate for new insulation. This also lets us inspect wiring and framing you haven’t seen in years.
Pest Debris and Sanitizing
Squirrels and rats love old Highland Park attics. After removing nesting material and droppings, we sanitize the decking and accessible framing. It’s a dirty job, but it extends the life of your new insulation and improves indoor air quality downstairs.

Trusted Brands We Service in Highland Park
We keep materials from eight manufacturers on hand so the right product goes into your attic, not whatever is left on the warehouse shelf. For Highland Park’s older, unvented roof assemblies, we most often reach for GreenFiber cellulose, which fills irregular rafter bays better than batts, and CertainTeed fiberglass for standard ventilated attics. We also work with Icynene open-cell spray foam when a homeowner wants air-sealing and insulation in one pass. No single brand is right for every Highland Park home, and we’ll tell you plainly which one fits yours.
Common Attic Insulation Problems We See in Highland Park Homes
- Knob-and-tube wiring buried under new insulation. Older installers frequently blew fiberglass right over live knob-and-tube circuits, creating a genuine fire hazard. We coordinate with a licensed electrician to verify and address wiring before any insulation goes down.
- Moisture trapped behind original sheathing. Unvented slate or tile roofs in 1920s homes need baffles and airflow planning. Insulating without addressing ventilation rots the roof deck from the inside out.
- Settled 1950s-era insulation doing nothing. Many Highland Park attics still have three or four inches of compressed Rockwool that lost its R-value decades ago. It looks like insulation, but it isn’t insulating.
- Preservation-code conflicts from prior unpermitted work. We’ve corrected attics where someone added ridge vents or roof-mounted radiant barriers that the town never approved. Getting it right the second time costs more than doing it right the first time.

FAQs About Attic Insulation in Highland Park
Highland Park’s preservation codes generally do not restrict insulation depth or material inside the attic cavity itself, but they do restrict visible exterior alterations like new ridge vents, roof-mounted radiant barriers, or changes to original masonry details. The practical effect is that we design retrofits from the inside: soffit baffles, interior radiant barriers, and insulation that fits existing framing without modifying the roofline. Call (361) 607-0906 and we’ll walk through what your specific home allows.
No. You should never place insulation over live knob-and-tube wiring. The wiring runs hot by design, and covering it traps heat against century-old insulation jackets, which is a fire hazard. The correct sequence is to have a licensed electrician evaluate and, where needed, rewire or decommission those circuits first, then insulate. We coordinate that process for you so the attic is safe before any material goes down.
Yes. Slate and clay tile roofs are far less forgiving of trapped moisture because they don’t ventilate the way asphalt shingle decks do. On these homes, we install soffit-to-soffit baffles and avoid sealing the attic too tightly, which keeps condensation from forming behind the sheathing. Getting this wrong rots a 90-year-old roof deck you cannot see from the living room. Call (361) 607-0906 for an assessment specific to your roof type.
Yes, absolutely. Blowing new insulation over old debris locks in allergens, pest droppings, and deteriorating material, and it prevents proper air-sealing at the attic floor. We clean first, then insulate. In Highland Park, a full attic cleanout before insulation runs $1,200 to $2,800 depending on attic size and condition.
The short answer: radiant barrier reflects heat, insulation slows heat conduction. They do different jobs. A radiant barrier on the rafters is the better first move in an unvented slate-roofed Highland Park attic because it works without changing the roof, while insulation depth is often limited by shallow rafter bays. In many of these homes, we do both: barrier above, blown-in cellulose below. Call us for the cost breakdown on your specific attic.
