You might be surprised by what you discover.

Average Cost of Spray Foam Insulation in 2026

After helping hundreds of Texas property owners tackle their insulation needs, we’ve seen spray foam insulation price 2026 trends stabilize around some clear ranges. Most homeowners can expect to pay between $1.50 and $5.50 per square foot for professional spray foam installation.

Typical residential projects fall into the $2,000 to $6,000 range for most Fort Worth and Weatherford area homes. Smaller jobs might start around $1,500, while extensive whole-house applications can push past $30,000.

Most insulation companies set minimum service fees between $1,000 and $2,000, which covers their equipment setup and travel costs.

We tell our clients upfront that spray foam costs more than fiberglass, but the air sealing benefits often justify the investment for drafty homes or commercial buildings with comfort issues.

Cost by Foam Type

The type of spray foam you choose makes a big difference in your wallet. We see two main options in Texas homes, and each comes with its own price tag that can swing your project budget by thousands.

Open-Cell Foam Costs

Open-cell foam delivers solid value for Texas property owners looking to upgrade their insulation game. Here’s what we see across projects in our area:

Open-cell foam runs between $0.90 and $1.60 per square foot across most residential and commercial applications. Projects in the Dallas-Fort Worth area typically fall closer to the higher end of this range. Smaller jobs under 500 square feet often cost more per square foot due to setup requirements.

Wall installations represent the sweet spot for open-cell applications. This foam type excels in cavity fill situations where you need good thermal performance without breaking the bank. Attic applications work well too, especially in older homes where air sealing matters more than maximum R-value.

Thickness affects your final bill significantly. Standard 3.5-inch wall cavities use less material than deeper applications. Six-inch walls or custom thickness requirements push costs toward the upper range. Labor makes up roughly 60% of your total project expense in most cases.

Commercial properties see similar per-square-foot pricing, though larger projects often qualify for volume discounts. Warehouse spaces, office buildings, and retail locations benefit from open-cell’s sound-dampening properties alongside thermal benefits.

Closed-Cell Foam Costs

Closed-cell foam brings higher upfront costs but delivers superior performance for Texas properties.

Material costs for closed-cell foam run higher than open-cell options. We’ve found that property owners appreciate the long-term value despite the steeper initial investment. R-value performance exceeds other insulation types significantly.

Moisture resistance sets closed-cell foam apart in Texas humidity. Basements and crawl spaces benefit most from this protection. Installation thickness affects final project pricing substantially.

Labor expenses vary based on project complexity and location access. Weatherford area pricing stays competitive compared to Dallas-Fort Worth metro rates. Professional installation takes more time than traditional insulation methods.

Project size directly impacts per-square-foot costs. Larger installations spread fixed costs across more coverage area. Smaller projects carry higher relative expenses due to setup requirements.

Superior R-value means fewer inches needed for equivalent thermal performance. Closed-cell foam creates an air barrier while insulating simultaneously. This dual function saves money on separate air sealing work.

Cost by Area of Installation

Different areas of your home need different approaches, and the costs vary quite a bit. Your attic might run you less per square foot than your basement, while garages fall somewhere in between.

Attic

Attic spaces represent the most common area for spray foam insulation installation in Fort Worth homes. We’ve priced thousands of attic projects across the Weatherford area, and costs vary significantly based on several key factors.

Professional installation costs for attic insulation typically range from $50 to $100 per hour in the Texas market. Our crews charge within this range based on project complexity and access challenges. Minimum service fees for attic insulation projects are often set between $1,000 and $2,000 across most contractors.

Closed-cell foam is the more expensive option for attic insulation due to its superior R-value and moisture resistance properties. This material works particularly well in Texas climates where humidity control matters. Open-cell foam costs less upfront but requiresa thicker application to achieve similar insulation values.

Factors affecting attic insulation pricing include foam type, area size and accessibility, thickness, and R-value requirements. Labor rates fluctuate based on crew availability and seasonal demand. Preparation work adds to total project costs, especially in older homes with existing insulation removal needs.

Attic accessibility plays a huge role in final pricing. Walk-up attics cost less to insulate than crawl-space access areas. Low-pitched roofs require more time and specialized equipment. Ductwork and electrical obstacles increase labor hours significantly.

Thickness requirements depend on your target R-value goals. Most Texas attics need R-38 to R-49 insulation values for optimal energy efficiency. Closed-cell foam achieves these values with less thickness than open-cell alternatives. This thickness difference affects material costs and application time.

Basement or Crawl Space

Basement or crawl space spray foam insulation costs range from $1,200 to $5,000 in 2026. Closed-cell foam is effective for these moisture-prone areas because it provides superior air sealing and moisture resistance. Pricing for closed-cell foam runs between $1.30 and $3.10 per square foot. Installation costs depend on area size, accessibility, and preparation work, which adds $1 to $3 per square foot to your total project.

Professional installation labor rates typically range from $50 to $100 per hour across Texas. Extensive basement or crawl space projects may fall within an overall budget of $4,000 to $30,000 or more. We’ve observed many Fort Worth and Weatherford properties benefit from this investment, especially in older homes with moisture issues. The upfront cost pays off through lower energy bills and improved comfort throughout your home.

Garage

Moving from basements to another common area, garages present their own set of insulation challenges and costs. Garage insulation costs range from $1,200 to $4,200 in 2026, making it a significant investment for Texas property owners.

Open-cell foam serves as the cheaper option for garage insulation projects. Cost per square foot for open-cell insulation falls between $0.90 and $1.60, while closed-cell insulation ranges from $1.30 to $3.10 per square foot. Factors influencing garage insulation pricing include foam type, area size, accessibility, and labor rates. Professional installation costs for insulation can reach $50 to $100 per hour, depending on your specific location in Texas.

Commercial Spray Foam Insulation Costs

Commercial spray foam insulation cost runs significantly higher than residential projects. We typically see commercial jobs range from $1.50 to $5.50 per square foot, just like residential work, but the scale changes everything. Large warehouses, office buildings, and industrial facilities in Fort Worth and Weatherford often require 10,000 to 50,000 square feet of coverage or more.

Project minimums for commercial work start around $5,000 to $10,000 due to equipment mobilization and crew requirements. We’ve completed warehouse projects exceeding $100,000 for comprehensive insulation systems.

Open cell vs closed cell spray foam cost becomes crucial for commercial clients since closed-cell foam’s higher R-value often justifies the premium price for energy savings over time. Labor costs also increase because commercial installations require specialized equipment, safety protocols, and often work around business schedules.

Key Factors Affecting Spray Foam Insulation Cost

Project Size and Thickness

Project size directly impacts your spray foam insulation costs, Fort Worth and Weatherford homeowners face. Larger areas mean more material and longer installation times. A small attic might cost $1,500, while a whole-house project can run $8,000 or more.

We calculate spray foam cost by square feet, but bigger jobs often get better per-square-foot rates. Thickness requirements add another layer to your costs. Standard attic spray foam insulation cost includes 6-8 inches of open-cell foam or 3-4 inches of closed-cell. Thicker applications use more material and take longer to install.

Cold storage facilities might need 6 inches of closed-cell foam, doubling material costs compared to standard residential work. Higher R-value requirements mean more foam, which translates to higher expenses for your project.

Labor Costs

Size and thickness matter, but labor costs can make or break your spray foam budget. Professional spray foam insulation installation in Weatherford runs between $50 to $100 per hour for skilled technicians.

Job complexity drives up those hourly rates fast. Tight crawl spaces, steep attic angles, and hard-to-reach corners all bump up the final bill. Preparation work adds another $1 to $3 per square foot to your spray foam insulation cost.

Old insulation removal, structural repairs, and surface cleaning take time. Our crews often spend hours prepping before we even fire up the spray equipment.

New Construction vs. Retrofit

Labor costs directly impact your budget, but the timing of your project matters just as much. Building a new home gives contractors easy access to all areas. They can spray foam insulation before walls go up or drywall gets installed. This makes the job faster and cheaper.

Retrofit projects cost more because we work around existing structures. We might need to remove drywall, move furniture, or work in tight spaces. Access becomes tricky in finished homes.

Spray foam insulation cost in Fort Worth typically runs 20-30% higher for retrofit work compared to new construction. The extra time and careful prep work drive up labor expenses, but the energy savings still make it worthwhile for most Texas property owners.

How to Save on Spray Foam Insulation Costs

Spray foam insulation costs can eat into your budget fast, but smart planning makes a real difference. We’ve helped countless Texas property owners cut their spray foam expenses without sacrificing quality.

• Get multiple quotes from licensed contractors – Prices vary widely across Texas, and comparing at least three estimates helps you spot fair pricing and avoid overcharges.
• Bundle insulation projects together – Insulating your attic and crawl space at the same time often reduces labor costs per square foot compared to separate jobs.
• Choose the right foam type for each area – Open-cell foam costs less than closed-cell and works great for interior walls, while closed-cell makes sense for exterior applications.
• Schedule during off-peak seasons – Fall and early spring typically offer lower rates as contractors have more availability than during extreme weather months.
• Prep the work area yourself – Clearing furniture, removing old insulation, and cleaning surfaces can reduce labor hours and total project costs.
• Consider partial DIY for accessible areas – Small projects like rim joists or minor gaps can be tackled with spray foam kits, though major areas need professional installation.
• Ask about material discounts – Some contractors offer reduced rates when you purchase materials directly or during manufacturer promotions.
• Calculate spray foam cost by square feet accurately – Measure your spaces carefully to avoid overordering materials or paying for unnecessary coverage.
