What is Spray Foam Insulation?

Spray foam insulation is a liquid material that we spray directly into wall cavities, attics, crawl spaces, and other areas of your home or commercial building. The material expands rapidly after application, filling every crack, crevice, and gap it encounters. This expansion creates an airtight seal that fiberglass batts and blown-in insulation simply cannot match. 

Our building-science-first approach analyzes airflow and leakage paths before we spray, so we target the problem areas that actually matter for your comfort. According to the 2024 International Energy Conservation Code (IECC) guidelines for Texas, attics in the Dallas-Fort Worth area (Climate Zone 3) must meet a minimum insulation level of R-38 to R-49. 

Spray foam reaches these levels in far less thickness than traditional fiberglass, which makes it a practical solution for tight attic spaces and a code-compliant choice for new construction and retrofits alike.

• Stops air leaks through gaps, cracks, and unsealed penetrations.
• Blocks heat transfer through walls, attics, and crawl spaces.
• Resists moisture infiltration that degrades traditional insulation.
• Reduces drafts, hot spots, and cold spots throughout your home.

Spray foam insulation provides a tight seal and enhances energy efficiency for both new constructions and retrofits, making it particularly effective in improving comfort and energy efficiency in Texas’s variable climate.

We offer both open-cell and closed-cell spray foam options, and each type performs differently depending on your specific needs. The material works exceptionally well for air sealing and duct sealing processes, which means we’re not just insulating. We’re actually stopping the energy waste that happens when conditioned air leaks out through gaps and cracks.

The foam hardens within minutes, forming a solid barrier that blocks heat transfer, air infiltration, and moisture. In Texas’s variable climate, where summer heat and occasional winter cold swing hard, this tight seal makes a real difference in keeping your energy bills down and your indoor temperatures stable.

Types of Spray Foam Insulation

We work with two main spray foam options that serve different needs and budgets. Each type brings its own strengths, and understanding the difference helps you choose what works best for your Texas home or business.

Open Cell Spray Foam

Open-cell spray foam insulation is a softer, more flexible material that expands significantly after application. It fills cavities and gaps with impressive thoroughness, creating an excellent air seal throughout your home or commercial building.

Our crews in Weatherford and across the DFW area install open-cell spray foam regularly. Firsthand, we’ve seen how this material adapts to irregular spaces that traditional fiberglass insulation simply cannot reach.

Open-cell foam typically costs less than its closed-cell counterpart, making it an attractive option for Texas property owners watching their insulation costs in 2026 budgets. The material carries an R-value of around 3.6 per inch, which provides solid thermal resistance for most residential applications.

• Lower upfront cost compared to closed-cell alternatives.
• Excellent air seal for reducing HVAC strain and energy waste.
• Strong sound-dampening qualities due to its porous structure.
• Well-suited for Texas climates where humidity fluctuates seasonally.

Installation involves spraying the foam directly onto walls, attics, and crawl spaces, where it hardens into a lightweight barrier that reduces energy loss. This approach works particularly well in older homes throughout Glen Rose and surrounding areas where existing insulation has deteriorated over time.

Our spray foam insulation cost 2026 estimates for open cell applications reflect the material’s affordability combined with its performance benefits, offering homeowners and commercial property owners genuine value for their investment.

Closed Cell Spray Foam

Closed-cell spray foam insulation is our primary service for new constructions and retrofit projects across Texas. This dense material creates an air barrier that stops drafts, moisture, and heat transfer in their tracks. We apply closed-cell spray foam directly to walls, attics, crawl space insulation areas , where it expands and hardens into a protective layer. 

The result is better comfort in your home or commercial building, lower energy bills, and a structure that performs as it should. Our insulation contractors throughout the DFW area have seen firsthand how closed-cell spray foam transforms older properties that leak energy. We pair it with air sealing services to maximize building performance and energy efficiency, tackling the root cause of energy waste rather than just the symptom.

Before we spray, we remove your existing insulation. This clears the way for a clean installation and prevents problems down the road. We provide free estimates for closed-cell spray foam insulation services, including old insulation removal, so you know exactly what you’re getting into. This material lasts for decades without settling or degrading, which means your investment pays dividends year after year.

Factors Affecting the Cost of Removing Old Insulation

Removing old insulation requires careful planning, since several factors shape your final bill. What you pay depends on specifics about your home and the work involved.

Size of the Area

The square footage of your space makes a significant difference in your total removal and installation costs. A 1,000-square-foot attic costs far less to handle than a 5,000-square-foot commercial building. We measure every inch carefully to give you accurate estimates for removal and installation services. Larger areas naturally require more labor hours, more materials, and more time on the job.

The removal process changes significantly depending on how much space we’re dealing with. A small crawlspace presents one set of challenges, while a sprawling warehouse presents another.

• Attics, walls, and crawl spaces each require different removal techniques.
• Larger spaces mean higher overall costs, but the cost per square foot often decreases.
• Commercial structures typically need more extensive prep work than residential projects.
• Precise measurements help our team determine labor costs and material quantities with confidence.

Homeowners should measure their space before requesting an estimate. This simple step saves everyone time and prevents surprises when the quote arrives.

Type of Existing Insulation

What’s already sitting in your walls and attic significantly influences the cost of removal and replacement. All insulation removal jobs have different requirements, and we’ve worked with countless homes across Weatherford and the DFW area to know the difference.

Fiberglass blown-in insulation is common in many Texas attics, and removing it requires specialized equipment and careful handling. According to 2026 attic insulation removal pricing data, blown-in cellulose or loose fiberglass averages $0.60 to $1.00 per square foot to remove because crews can vacuum it out efficiently. Removing old fiberglass batts costs slightly more, around $0.80 to $1.10 per square foot, because workers must manually roll and bag each piece.

Knowing which type you have lets you estimate your baseline removal cost before you even make a call. Here’s what we see most often in Texas homes:

• Blown-in cellulose or loose fiberglass: Vacuumed out efficiently, lower removal cost per square foot
• Fiberglass batts: Manually rolled and bagged, slightly higher labor requirement
• Mineral wool: Requires more careful handling and additional labor time
• Asbestos-containing materials: Requires certified protocols and specialized teams, with the highest removal cost

Some older homes contain materials that complicate the removal process significantly. Our insulation contractors in Glen Rose and surrounding areas have encountered everything from decades-old mineral wool to asbestos-containing products requiring special handling. We always recommend a thorough inspection before quoting removal work, so there are no surprises in your final bill.

Labor Costs

Once we identify what type of insulation sits in your walls or attic, labor becomes the next significant part of the equation. Removing old insulation requires skilled hands, and our team knows this work thoroughly. The removal process varies based on what we’re pulling out. Fiberglass batts come out relatively quickly. Mineral wool takes longer. 

Asbestos-containing products, which we’ve encountered across many older homes in the DFW area, require special protocols and certified removal teams, which increases costs considerably. Our team at Lone Star Insulation brings over 50 years of combined experience to every job. We charge based on square footage, difficulty level, and how involved the removal becomes. 

Based on 2026 industry pricing guides for Texas spray foam contractors, most professionals also enforce a minimum project fee of $1,000 to $2,000, regardless of square footage, to cover the overhead of transporting and preparing their specialized chemical rigs. This is worth knowing if you’re considering a small job like a single outbuilding or utility room. Several factors push labor costs higher on any given project:

• Hazardous materials require certified removal protocols.
• Moisture damage or contamination in existing insulation.
• Hard-to-reach attic spaces or tight crawl spaces.
• Large or complex commercial building envelopes.

Cleanup adds time, too. Hauling debris away from your property takes real effort, and we factor that into our final estimate. Labor expenses typically run between 40 and 60% of your total project cost, depending on how much old insulation needs removal and how involved your building envelope proves to be.

We provide free estimates so you can see exactly what labor costs will affect your budget before we start work. Our installation process includes thorough preparation and complete cleanup, which means your property looks just as good after we leave as it did before we arrived.

Cost of Installing Spray Foam Insulation in Texas

When you’re ready to invest in spray foam insulation across Texas, the costs break down into two main categories that affect your bottom line differently.

Average Costs for Open Cell Spray Foam

Open cell spray foam costs less upfront than closed cell alternatives, making it a smart choice for many Texas homeowners and commercial property owners looking to improve their building envelope without breaking the bank.

Open cell foam expands significantly after application, filling gaps and crevices that traditional fiberglass insulation misses. Our crews have removed countless layers of old batts, blown-in cellulose, and deteriorated insulation before applying open-cell spray foam, and the expansion factor means we cover more surface area with less material waste.

Area size drives costs more than almost anything else. Existing insulation type affects removal time and labor expenses significantly. Fiberglass batts come out faster than old blown-in insulation that has settled and compacted over decades. Commercial buildings often require more extensive prep work than residential projects.

Average Costs for Closed Cell Spray Foam

Closed-cell spray foam pricing varies considerably across the Dallas-Fort Worth area, and understanding the breakdown helps you make solid decisions for your property. Here’s what Texas homeowners and commercial property owners typically encounter:

Closed-cell spray foam costs more upfront than fiberglass blown-in or batt insulation, but the performance difference justifies the investment. A two-inch layer of closed cell delivers R-13 to R-15, meaning you need less thickness to reach your target insulation level. Your energy bills drop noticeably because the material achieves higher R-values per inch compared to open-cell alternatives.

Closed-cell spray foam installation protects your investment for decades. The material resists moisture, supports structural loads, and maintains its R-value performance year after year. We prioritize professional installations with careful attention to cleanliness and work area protection, ensuring no mess spreads through your home or commercial space.

Benefits of Upgrading to Spray Foam Insulation

Upgrading to spray foam insulation transforms your home’s performance in ways that standard insulation simply cannot match. Here’s exactly what advantages await your property.

Energy Efficiency

Spray foam insulation seals air leaks that old insulation simply cannot reach, and this matters greatly in Texas, where extreme heat and cold stress our homes and buildings year-round. Homes with old, settled insulation lose conditioned air through gaps and cracks, forcing air conditioning and heating systems to work overtime. 

Lower utility bills follow naturally when we remove deteriorated insulation and install spray foam that creates an airtight thermal barrier. According to 2025 energy savings data for Texas homes, spray foam can reduce cooling costs by 30 to 50% in the extreme Texas heat, and the upgrade typically pays for itself completely within 3 to 5 years. That turns a high upfront cost into a short-term investment with a clear financial return.

A Fort Worth area attic retrofit with open-cell spray foam demonstrates this impact with real numbers. Before installation, the 1,500 square foot home ran its AC an average of 14 hours per day during summer months, consuming approximately 1,120 kilowatt-hours monthly for cooling. 

Three months after the spray foam installation, average AC runtime dropped to 9.5 hours per day, with monthly cooling energy use falling to 760 kilowatt-hours. That’s a 32% reduction in measured cooling energy during the monitored period.

• Cooling runtimes drop significantly in the first summer after installation.
• Monthly energy bills reflect the reduction within the first few weeks.
• Savings compound year after year as the foam maintains its performance.
• Both residential and commercial properties see measurable temperature control improvements.

Spray foam’s superior performance comes from its ability to expand and fill every cavity, crack, and void in your walls, attic, and crawl spaces. Energy savings depend on specific conditions at your property, so we provide free estimates to assess your exact situation and calculate realistic savings for your building.

Longevity and Durability

Spray foam insulation stands out because it lasts far longer than traditional materials like fiberglass batts or blown cellulose. We’ve seen spray foam systems protect homes and commercial properties for decades without significant degradation.

The material resists mold and moisture, two culprits that destroy conventional insulation over time. Unlike older insulation types that settle and lose effectiveness, spray foam maintains its R-value year after year. 

Texas weather throws everything at our homes, from intense heat to occasional freezing temperatures, yet spray foam adapts without cracking or deteriorating. Mold growth becomes nearly impossible in spray foam systems because the material itself resists moisture accumulation.

• Resists mold and moisture damage that destroys traditional insulation.
• Performs through extreme Texas temperature swings without cracking.
• No settling means no cold spots or drafts developing years down the road.
• Durable insulation protects other structural components from weather damage.

This resistance translates directly into cost savings on future insulation replacements. You won’t need to tear out and reinstall insulation every fifteen years, which means fewer disruptions and a stronger return on your initial investment.

Our clients appreciate that spray foam improves the lifespan of entire building envelope systems. Upgrading today means protecting your property’s value and comfort for the next several decades.

Conclusion

Switching from old insulation to spray foam is one of the smartest moves Texas homeowners can make for their comfort and wallet. Removal costs run between $1,000 and $3,000, while spray foam installation typically lands in the $1,500 to $3,500 range, depending on your space and the type you choose.
