Spray Foam Insulation Cost - Same-Day Service, Done Right the First Time

How Much Does Spray Foam Insulation Cost in Fort Worth?

Spray foam insulation in Fort Worth typically runs $2.75 to $5.50 per board foot for open-cell and $4.00 to $7.00 per board foot for closed-cell, with most whole-attic jobs landing between $3,200 and $8,900 depending on square footage, R-value, and whether the space already has old insulation to remove. Most Fort Worth homeowners we work with pay roughly $4,800 for a standard 1,500-square-foot attic with closed-cell foam at 3 to 4 inches of depth.

Those are real numbers from our work across Fort Worth neighborhoods like Ryan Place, Wedgwood, the Near Southside, Benbrook, and Saginaw. The range exists because no two attics are the same: some have vaulted ceilings, some have ductwork running everywhere, and some still have 30-year-old batts that have to come out before new foam goes in.

Spray Foam Insulation Cost Breakdown (2026)

Here’s what we’re actually quoting for our Spray Foam Insulation services in Fort Worth right now, based on the types of jobs that come through Laurel Attic Insulation:

So what moves a project from the low end to the high end? Four things mostly: square footage, foam type, prep work, and season. Closed-cell costs more per board foot because it does more per inch, it’s denser, it acts as a vapor barrier, and it air-seals better. Prep work includes removing old fiberglass batts, sealing around existing penetrations, protecting surfaces, and sometimes fixing the access hatch just so we can get the rig inside. And Fort Worth summers matter: when the attic is 140 degrees in July, the job takes longer and sometimes needs scheduling at dawn, which can add a small premium.

What Affects Spray Foam Insulation Pricing in Fort Worth

• Square footage and attic geometry. A square 1,000-square-foot attic with a flat ceiling is a fast, clean job. A 1,000-square-foot attic with dormers, low knee walls, and a complex roofline takes twice the labor. The foam itself is priced by the board foot, but labor and rig setup time vary with access.
• Foam type: open-cell vs. closed-cell. Open-cell is lighter, quieter, and cheaper per board foot. Closed-cell is the better choice when you need a vapor barrier or higher R-value per inch, both common needs in North Texas humidity.
• Existing insulation condition. If the attic still has the original 1990s batt insulation that’s been trampled by cable installers and squirrels, it needs to come out before foam goes in. Removal runs $1.25 to $2.00 per square foot and adds to the total. Spraying on top of old batts is a bad job, and we won’t do it.
• R-value target. Fort Worth falls in climate zone 3 according to the Department of Energy. That typically means R-38 to R-60 in the attic. Closed-cell foam hits R-6.5 to R-7 per inch, so around 6 inches for R-38. Open-cell gives you R-3.7 per inch, so you’d need 10-plus inches to hit code-reflective values. Depth of foam drives board-foot count, which drives price.
• Air-sealing complexity. Spray foam only works at its best when it’s sealing, not just insulating. In older Fort Worth homes like those in Arlington Heights or Mistletoe Heights, we regularly find gaps around plumbing stacks, recessed lights, and kneewall access doors. Fixing those before we spray is part of a proper job and adds a few hundred dollars. Skipping it means lower performance, which you don’t want.
• Time of year and lead time. Fort Worth’s heat means summer is our busiest season, and lead times stretch out. Spring and fall projects sometimes get slightly better scheduling flexibility. Pricing from us stays stable through the year, but if a manufacturer raises material costs, that shows up on the next month’s quotes, not retroactively.

Open-Cell vs. Closed-Cell: What Fort Worth Homeowners Should Know

This decision changes your price by 30 to 45 percent, so it’s worth understanding what you’re actually paying for. Both are foam. Both air-seal. The difference is what they do with moisture and structural support.

Open-cell spray foam costs less per board foot and expands dramatically, filling cavities well. It’s spongy. It lets moisture pass through, which in a Fort Worth attic is usually fine because we have ventilation designed for that. It also dampens sound. The downside is that it needs more inches to reach the same R-value.

Closed-cell spray foam cures hard and dense. At 2 inches, it acts as a vapor barrier, which is useful in our humidity-heavy summers when outdoor air seeps into attic spaces and condenses. It doesn’t absorb water. It adds shear strength to a roof deck, a real benefit in a region that sees periodic hailstorms and high wind events. But it costs more, and it’s overkill for some interior applications.

Chase Whitaker, owner at Laurel Attic Insulation, puts it this way: most Fort Worth homeowners don’t need closed-cell everywhere. They need it in the right places, like rim joists, cathedral ceilings where venting is tight, and anywhere the roof deck itself is being unvented. Open-cell handles the big open attic floor well. We quote the job based on what the house actually asks for, not on a one-size formula.

Spray Foam vs. Other Insulation: Cost Comparison for Fort Worth

Here’s how spray foam stacks up against what most Fort Worth homes currently have in the attic, in terms of real market pricing:

• Fiberglass batt insulation: $1.10 to $1.85 per square foot for installation. The cheapest up front, but it doesn’t air-seal. In a Leaky Texas attic it’s usually not enough alone to fix a hot upstairs.
• Blown-in fiberglass: $1.50 to $2.30 per square foot for R-38. Great value, decent fit for open flat attics. But it settles and doesn’t stop air movement through gaps.
• Blown-in cellulose: $1.65 to $2.75 per square foot for R-38. Performs slightly better than fiberglass in actual North Texas wind and heat cycles because it fills tighter and slows air movement more effectively.
• Spray foam: $4.00 to $7.00 per square foot for closed-cell at code-meeting depths. Highest up front, but it’s the only one that insulates, air-seals, and acts as a vapor barrier in one pass.

For most of our Fort Worth customers, the decision comes down to whether the goal is “make my existing attic a bit better” or “fix my energy bills and second-floor comfort for good.” Both are valid projects. We install all of the above and we’ll tell you the truth about which one fits your roof.

How to Save on Spray Foam Insulation

Spray foam is a premium product and the price reflects that, but there are legitimate ways to keep the bill reasonable without cutting corners:

• Compare quotes on the same spec, not just the same phrase. One contractor may quote open-cell and another closed-cell, two very different products. Ask for R-value, foam type, and depth on every quote so you’re comparing identical work.
• Check for rebates and efficiency incentives. Some Fort Worth utilities and state programs offer home efficiency rebates that partially offset insulation upgrades, particularly when a professional energy audit is done first. The programs shift year to year, but it’s worth a search before you commit.
• Bundle removal and installation. If the old insulation has to come out, having the same crew remove and spray in one visit is usually cheaper than coordinating two companies on two schedules.
• Time it outside peak summer. Schedule the work in late fall or late winter when Fort Worth’s attic temps are tolerable and our crews aren’t burning daylight. Pricing stays consistent, but you’ll get a better choice of dates.
• Get a written quote that names the foam, the depth, and the total. That’s not a savings tip, it’s a protection against paying twice. At Laurel, you get a written price before anything begins. Call (817) 730-5474 for a free estimate and we’ll walk you through the numbers for your specific attic.

Why the Price Doesn’t End at Installation

Spray foam done properly is a decades-long asset. Done poorly, it’s an expensive problem. In Fort Worth, we see three recurring mistakes from rushed installs: foam that’s sprayed too thin to meet the R-value quoted, foam applied over dust and debris so it doesn’t bond, and foam expanding into soffit vents and choking off attic ventilation, which then drives up the attic moisture load in our humid months.

Each of those failures costs $2,000 to $7,000 to correct. The cheapest quote is often not the cheapest outcome.

Here’s what you should expect from a Fort Worth spray foam contractor before you agree to anything:

• Written scope-of-work. Exact square footage, foam type, target R-value, and total price. Not a verbal shrug.
• Material brand named. We use Icynene, Demilec, and other equipment-matched products from manufacturers that train their applicators. Your quote should say what foam is going in.
• Photo evidence. Before-and-after pictures of the work. Everyone has a phone; there’s no reason not to document a four-figure project.
• A real warranty in writing. Ours is a 365-Day Done Right Promise: if it’s not done right, we make it right, in writing, every time. Plus a free second visit if the repair fails, no charge and no argument.

Chase and the Laurel crew work this way because we started in 2003, when most jobs were handshake deals and the homeowner got whatever the truck had on it. Today the Laurel standard is different. You can book through the company, get a live technician arrival time, watch photo updates, and pay from a link when the job is done. That’s the Relay Visibility Guarantee, and spray foam pricing should carry the same transparency as everything else.

FAQs – Spray Foam Insulation Cost

How much does spray foam insulation cost per square foot in Fort Worth?

Spray foam in Fort Worth runs $2.75 to $7.00 per square foot depending on whether you’re using open-cell or closed-cell and how deep the foam is applied. Open-cell is the lower end of that range, closed-cell the higher end. Call (817) 730-5474 for a free, itemized estimate with the foam depth we recommend for your roof line.

Is spray foam worth the cost compared to fiberglass?

Spray foam typically costs 2 to 3 times more than fiberglass up front, but it’s the only insulation that both air-seals and insulates, which is exactly what a Fort Worth attic in August needs. Fiberglass lets air drift through gaps around pipes and wiring; spray foam seals those gaps and holds heat out. For the right home, the payoff is a cooler second story and lower peak summer bills, not just a thicker blanket.

Can you install spray foam insulation in an existing Fort Worth home?

Yes. Most of the retrofit spray foam work we do in Fort Worth is in existing homes, typically 1980 to 2010 construction. The job involves clearing the attic, addressing any gaps around penetrations, and then spraying either the attic floor or the roof deck depending on how the home is vented. The work typically takes one to two days. A free estimate will tell you if your attic is a good candidate.

Is it cheaper to repair or replace existing insulation?

For most Fort Worth attics with settled, thin, or trampled insulation, removal and fresh spray foam is the better long-term investment versus patching spots. A patch job runs $1,000 to $2,500 and leaves the same air leaks in place, while a full attic foam job runs $3,200 to $8,900 and addresses the whole system. If the existing insulation is in otherwise good shape, topping it off with blown-in material is the budget-friendly middle path.

Do I need a permit for spray foam insulation in Fort Worth?

Most insulation upgrades in an existing home don’t require a City of Fort Worth permit, but if the project includes changing the building envelope, such as converting a vented attic to an unvented assembly, a permit may be required. That’s a detail we handle on our side. Call (817) 730-5474 and we’ll check the specifics for your address before the job starts.

Will spray foam insulation lower my energy bill in Fort Worth?

Most Fort Worth homeowners see a 15 to 30 percent reduction in summer cooling costs after a proper spray foam retrofit, though the exact number depends on how much air leakage existed to begin with. The homes with the biggest “before” problem usually see the biggest improvement. It’s measurable: we recommend comparing a July bill from before the work to a July bill after.
