Fast, Reliable Spray Foam Insulation Across Forest Hill
Spray foam insulation in Forest Hill typically costs $1,800 – $4,600 for a standard attic application, depending on whether you choose open-cell or closed-cell and how much square footage needs coverage. Most Forest Hill jobs are completed in one day, and we answer the phone live around the clock. That matters when your 1962 ranch off Mansfield Highway is bleeding cool air into a 140°F attic and your upstairs bedrooms won’t drop below 80°F in July.
We know Forest Hill’s housing stock because we work in it every week: mid-century brick-veneer homes on slab foundations, original 1960s and 70s insulation that’s compacted or pulled away from the framing, and attics that punish under-insulated ceilings. Our crews dispatch to Forest Hill from the Dallas-Fort Worth metro office, and we carry the closed-cell and open-cell materials these homes actually need.

Why Laurel Attic Insulation Fort Worth Is Forest Hill’s Preferred Spray Foam Insulation Company
Forest Hill homeowners call us because we show up when we say we will. Every job runs on the Relay Visibility Guarantee: you book, you get a live arrival time, and you receive before-and-after photos of the work – no vague four-hour window, no wondering whether the crew actually sprayed what they said they sprayed. That level of visibility is rare in the insulation trade, and it’s exactly what Forest Hill’s homeowners have started asking for.
Our technicians are background-checked and uniformed. They know what a 1960s slab-on-grade ranch looks like inside the attic, and they know that original 1970s open-cell foam in Forest Hill frequently looks intact while performing like R-11. Chase Whitaker leads the team, and he holds every job to the 365-Day Done Right Promise: if the spray foam isn’t performing right within a year, we return and make it right in writing. No charge, no argument.
We also put the price in writing before work begins. You’ll see the line items: material type, board feet, prep work, cleanup. No door-step add-ons. Forest Hill customers get the same upfront pricing as every other job we run, and we answer calls 24/7 – a live person, not a voicemail queue.
Closed Cell Spray Foam Insulation in Forest Hill
Closed cell spray foam insulation is the denser, vapor-retarding option we install most often in Forest Hill when unvented roof decks or slab-moisture concerns are in play. It’s typically sprayed at 2 – 3 inches and creates an air seal and moisture barrier in one layer. In Forest Hill homes built before 1980, closed-cell is frequently the right call on rim joists, unvented attic roof decks, and anywhere ground moisture can wick upward through slab foundations into wall cavities.
What Closed-Cell Costs in Forest Hill
Closed-cell foam in Forest Hill runs $2.20 – $3.50 per board foot installed, which puts most rim joist jobs at $900 – $1,800 and full roof deck applications at $3,200 – $5,800 depending on roof geometry and access. It costs more than open-cell because the material is denser and delivers about R-6.5 per inch. You’re paying for structural rigidity, a built-in vapor barrier, and air sealing in one product.
When Your 1950s-70s Ranch Needs It
If you have an unvented attic roof in Forest Hill and you’re seeing condensation drip onto ceiling drywall during winter cold snaps, the closed-cell foam was either never applied or sprayed too thin. Under 2 inches on a 1950s ranch roof deck sweats at the foam-sheathing interface when the temperature drops. Closed-cell applied at code depth stops that. It also locks out the humid summer air that turns original cellulose into a mold risk.
Open Cell Spray Foam in Forest Hill
Open cell spray foam is the lighter, air-permeable option we apply in Forest Hill attics where ventilation exists and the goal is thermal performance plus air sealing at a lower material cost. It expands to fill joist bays, seals around ceiling penetrations, and typically lands around R-3.7 per inch. For Forest Hill homes with vented attics and existing ventilation that works, open-cell is often the most cost-effective way to stop the 140°F attic heat from pushing down through bedroom ceilings.
Typical Open-Cell Pricing in Forest Hill
Open-cell in Forest Hill runs $1.10 – $1.80 per board foot installed. A 1,200-square-foot attic sprayed to R-38 usually lands between $2,400 and $4,100. The final number depends on whether we’re removing degraded 1970s cellulose first, air-sealing rim joists, and how many ceiling penetrations need foam-sealing before the spray pass.
Where Open-Cell Works Best
Open-cell is the right fit for vented attic floors in Forest Hill’s brick-veneer and frame ranch homes. It fills irregular joist spacing, grabs onto old drywall and framing, and quiets the house as a side benefit. We don’t recommend open-cell on exterior walls of slab-on-grade 1960s homes, because ground moisture wicks up and makes the foam slump within a few years. That’s a closed-cell application in this soil.
Trusted Brands We Service in Forest Hill
We install spray foam from Johns Manville, Knauf, and CertainTeed, matched to the job rather than whatever happens to be loaded on the truck. For Forest Hill customers, that means open-cell projects often use Johns Manville or Knauf open-cell systems, while closed-cell rim joist and roof deck work leans on CertainTeed’s closed-cell lineup. Because we stock materials for the mid-century housing stock common in Forest Hill, turnaround is fast; most jobs are scheduled within a few days of your written quote, not weeks out. You won’t wait on a special order for a product that fits your home.
Common Spray Foam Insulation Problems We See in Forest Hill Homes
- Original 1970s foam that has shrunk away from joists. Many Forest Hill homes built before 1980 still have early-generation spray foam in attic floor cavities. It looks intact but has pulled back from the framing, leaving gaps that vent conditioned air straight into 140°F attics.
- New foam sprayed over degraded cellulose. Spray foam applied over original 1970s blown-in cellulose without removal traps moisture against the old material. In Forest Hill’s humid summers, that becomes mold on the attic side within a season or two.
- Closed-cell sprayed too thin on unvented roof decks. Under 2 inches on a 1950s ranch roof deck sweats at the foam-sheathing interface during winter cold snaps, and the first sign is water staining on ceiling drywall.
- Open-cell in slab-on-grade exterior walls slumping. 1960s slab homes in Forest Hill wick ground moisture upward into open-cell wall foam. The foam loses R-value and slumps within five years, which is why we specify closed-cell in those cavities.

FAQs About Spray Foam Insulation in Forest Hill
No, and we won’t do it because it fails in Forest Hill’s humid climate. The old cellulose needs to come out first, then we air-seal and spray. Spraying foam over original 1970s cellulose traps moisture against the old material, and within a season or two you’ll have mold on the attic side. Removal typically adds $1,200 – $2,200 to the project, and it’s the difference between a foam job that lasts 25 years and one that fails in five. Call (817) 730-5474 and we’ll inspect what’s actually up there and give you a written plan.
It’s common in Forest Hill’s 1950s-60s slab-on-grade homes, but it is not normal performance. Ground moisture wicks upward through the slab, and open-cell foam absorbs it, slumps, and loses R-value. The fix is removing the damp open-cell and spraying closed-cell in those wall cavities, because closed-cell acts as a vapor barrier and holds its structure. We see this regularly in the older neighborhoods around Mansfield Highway, and it’s a known failure mode specific to slab construction. Call us for a cavity-by-cavity assessment and quote.
Forest Hill homes need a minimum of 2 inches of closed-cell at the roof deck, and the code-correct approach for this climate zone is typically 3 inches or more. Under 2 inches sweats at the foam-sheathing interface during winter cold snaps, and that moisture drips onto your ceiling drywall. We quote roof deck projects at the depth that actually prevents condensation, not the minimum that makes a bid look cheap. Call (817) 730-5474 for a roof-deck inspection and a written price.
Remove the degraded foam, air-seal the rim joists with closed-cell, and spray a continuous open-cell layer to R-38 across the attic floor. That’s the exact sequence that fixes the 8°F temperature difference we found in a 1962 brick-veneer ranch off Mansfield Highway, and the fix typically runs $3,000 – $4,800. The temperature delta drops within a day of the spray pass. Call us and we’ll schedule an attic inspection this week.
It depends on the application. Closed-cell foam is its own vapor barrier at 2 inches or more, so unvented roof decks and rim joists don’t need a separate poly layer. Open-cell on attic floors doesn’t need one either, since the attic is vented. The place where Forest Hill’s slab homes need vapor control is exterior walls, and that’s precisely why those cavities get closed-cell. We’ll specify the right foam for each part of your home in the written quote. Call (817) 730-5474.
If your Forest Hill home has original spray foam that’s not doing its job, or you’re tired of paying July electric bills that match a car payment, call (817) 730-5474. We’ll send a background-checked tech with a live arrival time, hand you a written price before anything starts, and document the work with photos when it’s done. That’s the way spray foam insulation in Forest Hill should work.
