Attic Insulation in Garland - Same-Day Service, Done Right the First Time

Insulation in Garland, TX

Spray foam insulation in Garland runs $2.40 to $6.80 per board foot for open-cell and $3.60 to $8.40 for closed-cell, depending on the depth and surface. Most homes here are slab-on-grade brick ranches from the 1955 to 1978 building wave, framed with 2×4 walls and original attic insulation that has settled to R-11 or less, against a code minimum of R-38. Our crews seal the top plates, can lights, and penetrations before any insulation goes in, then publish the before-and-after blower-door numbers on every applicable job. Call (218) 261-7714 for a written price before any work starts.

Why Garland Homes Are Different

Garland grew fast. Around 10,000 residents in 1950 became over 100,000 by the late 1970s, and that boom produced tens of thousands of slab-on-grade tract homes built before Texas had a residential energy code. Walk through the Firewheel area or the neighborhoods off Broadway and Saturn Road, and you’ll see the same house repeated block after block: brick veneer over 2×4 framing, a shallow attic, and original insulation that has compacted to under three inches. We find unsealed top-plate penetrations in those attics so consistently that it’s nearly a baseline expectation before the job even starts.

Climate Zone 3A means Garland attics top 140°F every summer and occasionally drop below freezing in hard winter events like February 2021’s Uri, which exposed exactly how under-insulated these older homes were for cold. Because the housing stock sits almost entirely on slab foundations with no crawl spaces, the work concentrates in two places: attic floors and wall cavities. The thermal failure repeats house to house because the construction pattern repeats house to house. That’s why our air-sealing-before-insulation sequence matters more in Garland than in a city with newer, mixed housing stock.

Our Main Garland Services

Garland homeowners call us most often about two problems: attic insulation that has settled below any functional R-value, and the rare crawl space homes on the city’s perimeter that need vapor control. Here’s what each involves locally.

Attic Insulation in Garland

Most Garland attics we open are holding three to four inches of compressed fiberglass or cellulose, which tests out around R-11 in a zone that requires R-38. We air-seal the attic floor first, then blow new insulation to depth. Before-and-after blower-door readings come with the job. Read the full breakdown on Attic Insulation in Garland.

Crawl Space Encapsulation & Vapor Barrier in Garland

Crawl spaces are uncommon in Garland’s slab-heavy center, but they appear in pockets along the city’s eastern and northern edges, where humidity from mixed-humid summers pushes moisture up into floor framing. We install vapor barriers and encapsulation systems where the terrain calls for it. Details are on the Crawl Space Encapsulation & Vapor Barrier in Garland page.

Spray Foam Insulation in Garland

Spray foam insulation in Garland answers two problems at once: the 140°F attic heat that radiates through thin original insulation, and the air leakage through unsealed top plates that we find in nearly every 1955-to-1978 ranch home. Our Spray Foam Insulation work here starts with a written scope and ends with a documented record. On homes with vaulted ceilings or attached garages in the Firewheel area, closed-cell foam on the roofline is often the only practical way to bring the assembly to current code performance.

Open-Cell Spray Foam

Signs you need it

Your upstairs rooms run 8 to 10 degrees warmer than the rest of the house in summer, and the attic floor insulation has settled to R-11 or less.

What it costs in Garland

Open-cell spray foam runs $2.40 to $4.80 per board foot installed in Garland attics, depending on depth and access.

How we do it

We seal top plates and penetrations first, then spray open-cell foam to the specified depth across the attic floor or roofline, followed by a blower-door reading.

Closed-Cell Spray Foam

Signs you need it

Your unvented attic or roofline lacks an air barrier, or you’re converting a garage ceiling to conditioned space and need R-value per inch.

What it costs in Garland

Closed-cell spray foam in Garland runs $3.60 to $8.40 per board foot, with garage ceiling projects typically at the lower end of that range.

How we do it

We prep the surface, spray closed-cell foam to the design thickness, and document the finished depth with photos and a post-work air-sealing measurement.

What Spray Foam Insulation Costs in Garland

Costs climb when the roof deck is steep or access is tight, which describes a fair number of Garland’s 1960s and 1970s ranches with low-slope hips and shallow attic hatches.

Is spray foam worth it in Garland’s climate?

Yes, for most homes. Mixed-humid Climate Zone 3A means the foam must perform in both directions: blocking 140°F attic heat in summer and holding heat during hard freezes like Uri. Closed-cell does both.

How long does spray foam last in a Garland attic?

Indefinitely when installed correctly and kept dry. The foam doesn’t settle or compress like blown material, which is the primary reason it outperforms the original insulation in older Garland homes over time. Call (218) 261-7714 for a written price.

Blown-In Insulation in Garland

Blown-in insulation in Garland is the standard retrofit for attics in the city’s 1955-to-1978 ranch stock, where original fiberglass has settled to R-11 or less and the code minimum now demands R-38. Our Blown-In Insulation crews seal the attic floor before any material goes down, so the new insulation isn’t just covering the same air leaks the old layer sat on top of. Homeowners get a before-and-after blower-door reading on every applicable job.

Blown-In Cellulose

Signs you need it

Your attic has settled material under three inches deep and the house runs hot upstairs in Garland summers.

What it costs in Garland

Blown-in cellulose in Garland attics runs $12.50 to $19.50 per square foot installed, with most ranch homes landing in the middle.

How we do it

We air-seal the attic floor, mark the depth gauges, then blow cellulose to R-38 or the specified target and document the result.

Dense-Pack Wall Insulation

Signs you need it

Your 2×4 exterior walls feel cold in winter and the wall cavities are empty or holding only thin fiberglass batts.

What it costs in Garland

Dense-pack wall insulation runs $14.50 to $26.00 per square foot in Garland, depending on siding type and cavity access.

How we do it

We drill access holes, dense-pack cellulose or fiberglass into each cavity, then plug and finish the holes and record the work.

What Blown-In Insulation Costs in Garland

Prices rise in Garland when the attic has old vermiculite that must be removed first, which we see occasionally in the city’s older core neighborhoods.

How much blown-in insulation does a Garland attic need?

Code minimum in Climate Zone 3A is R-38, which translates to roughly 12 to 14 inches of settled cellulose or fiberglass. Most existing Garland attics hold less than half that.

Can you blow insulation over my existing attic insulation in Garland?

Usually yes, after we confirm the existing material is dry, uncontaminated, and properly settled. We never blow new insulation over an unsealed attic floor, which is the situation in nearly every Garland ranch home. Call (218) 261-7714 for a written scope.

Radiant Barrier Installation in Garland

Radiant barrier installation in Garland attacks the single biggest summer load: 140°F attic heat radiating down through the ceiling into the living space below. Our Radiant Barrier Installation work combines the foil layer with proper attic ventilation, because a radiant barrier without airflow doesn’t perform in Garland’s mixed-humid summers. Homes in the Firewheel area and central Garland see the largest cooling-load reductions from this retrofit.

Attic Radiant Barrier

Signs you need it

Your attic temperature climbs past 140°F on summer afternoons and the air conditioner runs almost continuously from June through September.

What it costs in Garland

Attic radiant barrier in Garland runs $4.60 to $7.80 per square foot installed, depending on attic size and roof geometry.

How we do it

We staple or fasten the foil to the underside of the rafters, leave the required air gap, and verify attic ventilation before finishing.

Radiant Barrier & Ventilation

Signs you need it

Your attic has ridge or soffit venting that’s blocked or undersized, so heat has nowhere to go even with insulation in place.

What it costs in Garland

Combined radiant barrier and ventilation corrections run $4.60 to $7.80 per square foot in Garland, with ventilation upgrades priced by the linear foot of venting added.

How we do it

We install the barrier, open or add soffit and ridge vents to restore airflow, then document the finished assembly with photos.

What Radiant Barrier Installation Costs in Garland

Costs move higher on Garland homes with steep or multi-plane roofs, where the extra labor shows up in the installed price before we write the scope.

Does radiant barrier help in Garland winters?

Minimally. It’s a summer tool: in mixed-humid Zone 3A, the foil reflects radiant heat back out of the attic. It adds negligible R-value for cold nights, which is why we pair it with air sealing and blown insulation.

Can radiant barrier replace insulation in a Garland attic?

No. Radiant barrier reduces heat transfer by radiation but doesn’t stop conduction. Garland code still requires R-38 attic floor insulation even with a barrier installed. Call (218) 261-7714 to get a written price for both.

Insulation Removal & Replacement in Garland

Insulation removal and replacement in Garland is most often driven by one of two findings: vermiculite or animal contamination in the attic of a 1960s-era ranch, or insulation that has compacted and failed after decades of Garland’s heat-and-freeze swings. Our Insulation Removal & Replacement crews vacuum out the old material, sanitize the attic floor, and replace it with new insulation at current code depth. We photograph the attic before and after, and you get those images in the job record.

Attic Insulation Removal

Signs you need it

Your attic insulation has settled to under three inches, shows signs of moisture damage, or contains material you suspect is vermiculite.

What it costs in Garland

Attic insulation removal in Garland runs $3.50 to $7.00 per square foot, with smaller ranch attics at the upper end per square foot.

How we do it

We set up negative-pressure containment, vacuum out the old material, bag it for disposal, and photograph the empty attic before new work begins.

Contaminated Insulation Removal

Signs you need it

You’ve had rodents or wildlife in the attic, and the insulation is stained with droppings or urine, which carries health risk year-round in Garland’s heat.

What it costs in Garland

Contaminated insulation removal in Garland runs $3.50 to $7.00 per square foot, plus sanitizing and decontamination at $2.00 to $4.00 per square foot.

How we do it

We remove all contaminated material under containment, sanitize the attic surfaces, and prepare the space for new insulation to code depth.

What Insulation Removal & Replacement Costs in Garland

Vermiculite removal in Garland runs higher because it requires specialized handling and disposal, and we treat every vermiculite job as a potential asbestos-containing material unless testing says otherwise.

How do I know if my Garland attic has vermiculite insulation?

Vermiculite is a pebbly, granular material that shimmers, usually gray-brown or silver. In Garland’s 1950s and 1960s homes it’s often mixed with fiberglass. We test before removal.

Is it cheaper to replace insulation or add more on top in Garland?

Adding more is cheaper up front when the existing insulation is dry and uncontaminated. But if moisture or rodent damage is present, replacement is the only option that won’t leave the problem sealed under new material. Call (218) 261-7714 for a written recommendation.

Attic Air Sealing in Garland

Attic air sealing in Garland is our hard prerequisite before any insulation goes in, and it’s the single highest-return retrofit for the city’s 1955-to-1978 ranch stock. Our Attic Air Sealing work targets the unsealed top plates and penetrations we find in nearly every older Garland attic. In the Firewheel area and central neighborhoods, we regularly measure homes losing 4,000 CFM50 or more before sealing, and half that after, which is the entire point of the blower-door reading we publish on every job.

Top Plate & Penetration Sealing

Signs you need it

Your attic floor has visible gaps where drywall meets the top plates, and plumbing or electrical penetrations show daylight or dust trails.

What it costs in Garland

Top plate and penetration sealing in Garland runs $7.00 to $12.00 per linear foot for top plates and $20 to $50 per penetration, depending on size and access.

How we do it

We remove or move aside existing insulation, seal every top plate and penetration with foam or caulk, then verify with a blower-door reading.

Can Light & Duct Boot Sealing

Signs you need it

Your recessed lights feel warm to the touch or you can feel air moving around ceiling registers when the HVAC runs.

What it costs in Garland

Can light and duct boot sealing in Garland runs $20 to $60 per fixture or boot, with older non-IC-rated lights requiring a box or cover first.

How we do it

We cover or box each non-IC fixture as required, seal the trim and housing to the drywall, and seal duct boots with mastic or foam.

What Attic Air Sealing Costs in Garland

Prices move higher in Garland when the attic has deep blown insulation that must be temporarily moved aside to reach the top plates, which is common in homes that got a quick blow-in job years ago without any sealing underneath.

Does air sealing really make a difference in Garland’s climate?

Yes, and we measure it. The blower-door test shows the CFM50 number before and after sealing. Typical Garland ranch homes drop 30 to 50 percent, which translates directly to lower cooling costs in summer.

Can I air seal my own attic in Garland?

You can, but the risk of missing the dominant leaks is high, and the work involves working in confined, hot attic spaces. We recommend a trained crew with blower-door verification, because the number is the proof. Call (218) 261-7714.

Wall Insulation in Garland

Wall insulation in Garland is a retrofit that’s almost always driven by one discovery: the 2×4 exterior walls in a 1960s or 1970s ranch are empty or hold only a thin fiberglass batt. Our Wall Insulation work addresses exactly that cavity profile, most often with drill-and-fill dense-packing from the exterior. On Garland’s brick veneer ranches, that means working through the mortar joints or siding, which is a slower process but leaves the wall complete and ready to paint.

Injection Foam Wall Insulation

Signs you need it

Your exterior walls feel cold to the touch in winter and the rooms along perimeter walls are noticeably warmer than the interior of the house.

What it costs in Garland

Injection foam wall insulation in Garland runs $14.50 to $26.00 per square foot, depending on cavity depth and access from the exterior.

How we do it

We drill small access holes at each stud bay, inject the foam to fill the cavity, then plug and finish the holes to match.

Interior Wall Soundproofing

Signs you need it

You hear traffic or neighbors through shared or exterior walls, and the wall cavity currently has no insulation mass.

What it costs in Garland

Interior wall soundproofing in Garland runs $14.50 to $26.00 per square foot, with wall height and existing drywall conditions moving the number.

How we do it

We dense-pack the cavities or install batt and board products, then document the finished wall assembly with photos and a written record.

What Wall Insulation Costs in Garland

Garland’s brick veneer construction usually adds labor to wall retrofits because access holes must be carefully placed through mortar joints rather than drilled freely through siding, and we match the finish afterward.

Can you insulate walls without removing drywall in Garland?

Yes, drill-and-fill and injection foam are both done from the exterior through small holes, so interior walls stay intact. The process leaves small plugged holes that can be painted over.

How do I know if my Garland home even has wall insulation?

A thermal imaging scan during an energy audit reads the wall temperature pattern and shows the empty or partially filled cavities. That’s the reliable way before drilling anything. Call (218) 261-7714 to schedule one.

Attic Cleaning & Rodent Proofing in Garland

Attic cleaning and rodent proofing in Garland is a necessary first step before any insulation work when squirrels, rats, or mice have been living in the attic. Our Attic Cleaning & Rodent Proofing crews remove the contaminated material, sanitize the surfaces, and seal the entry points so the next insulation job doesn’t become a new nest site. In Garland’s older ranch neighborhoods, the typical entry path is a gap at the soffit or a torn attic hatch gasket, and we document every one we close.

Attic Cleanout

Signs you need it

You see droppings, nesting material, or chewed wiring in the attic, or you’ve heard movement overhead at night.

What it costs in Garland

Attic cleanout in Garland runs $3.50 to $7.00 per square foot, plus disposal fees, with smaller attics at the higher per-square-foot end.

How we do it

We vacuum out all loose insulation and debris under containment, bag it for disposal, and photograph the empty attic before sanitizing.

Rodent Proofing & Exclusion

Signs you need it

You’ve had repeated rodent activity despite trapping, which means the entry points were never sealed.

What it costs in Garland

Rodent proofing and exclusion in Garland runs $30 to $60 per linear foot of sealing, plus the cost of any trim or flashing repairs needed at the entry points.

How we do it

We locate every entry point, seal it with steel mesh or metal flashing, and verify the attic stays clear with a follow-up inspection.

What Attic Cleaning & Rodent Proofing Costs in Garland

Removing insulation that rodents have lived in isn’t optional before adding new material. Garland’s heat accelerates the odor and the health risk, so we sanitize before any insulation replacement happens.

Do I need to remove insulation after rodents in Garland?

Yes, if the insulation is contaminated with droppings or urine. Blowing new material over it seals the problem in place. We remove, sanitize, and then replace at code depth.

Can you prevent rodents from returning to my Garland attic?

Exclusion works when every entry point is sealed with materials rodents can’t chew through, and we back the work with the 365-Day Done Right Promise. Call (218) 261-7714 for a written scope before work starts.

Home Energy Audit in Garland

A home energy audit in Garland measures the exact problems this city’s older housing stock is known for: settled attic insulation, unsealed top plates, and under-insulated 2×4 walls. Our Home Energy Audit uses a blower-door test, a pressurization reading that shows in one number how much air your building envelope is losing, plus thermal imaging to find the specific gaps. Homeowners in the Firewheel area and central Garland typically walk away with a prioritized list of fixes in writing, with prices attached.

Blower Door Test

Signs you need it

Your energy bills swing hard between seasons, or rooms in the same house feel consistently different temperatures.

What it costs in Garland

A standalone blower door test in Garland runs $250 to $500, with most ranch homes at the lower end of that range.

How we do it

We mount the blower door in an exterior door frame, depressurize the house, and measure the CFM50 number before and after any sealing work.

Thermal Imaging Inspection

Signs you need it

You can feel drafts but can’t find the source, or you want documentation of where the wall cavities are missing insulation.

What it costs in Garland

A thermal imaging inspection in Garland runs $150 to $350 per scan, and it’s included with a full audit rather than charged separately.

How we do it

We scan exterior walls, ceilings, and floors with an infrared camera while the house is pressurized, then record the findings with images.

What Home Energy Audit Costs in Garland

Full energy audits in Garland run higher than single tests because they combine blower-door, thermal imaging, and a written prioritized scope with prices, but the bundled price is lower than ordering each separately.

Is a home energy audit worth it before buying a Garland home?

Yes. An audit on a 1960s ranch will typically show settled R-11 attic insulation, unsealed top plates, and empty wall cavities before you sign. That’s documented evidence for your purchase decision or negotiation.

What will the audit tell me about my Garland home’s insulation?

The audit measures the CFM50 air leakage, finds where the leakage is, and shows which cavities are missing insulation. You get a written report with photos and prioritized recommendations. Call (218) 261-7714 to schedule one.
