Optima SprayFoam is a licensed (CR-40 362887), insured, and ICAA-qualified spray foam contractor serving every neighborhood in Gilbert — from Power Ranch and Val Vista Lakes to Seville, Agritopia, Morrison Ranch, and Trilogy. We help Gilbert homeowners cut cooling bills, eliminate the dust and air leaks builder-grade insulation leaves behind, and turn 150°F attics into comfortable, conditioned space — backed by a lifetime warranty and our Dust-Free Guarantee.
Gilbert grew faster than nearly any town in America from the early 2000s to today, which means most Gilbert houses were framed and insulated to builder-minimum standards during the boom. R-30 fiberglass batts in the attic, paper-faced batts in the walls, and a thousand small air leaks at every can light, plumbing chase, and top plate. Adequate when the developer signed it off — not adequate at 116°F.
Gilbert summers push attic temperatures to 140–160°F, monsoon humidity drives moisture through every gap in the roof deck, and fine desert dust settles into batt insulation year-round. Homes in Power Ranch, Seville, Layton Lakes, Stratland Estates, and Adora Trails routinely report upstairs bedrooms that never cool below 80°F in July, regardless of how hard the AC works.
Spray foam insulation solves this at the source. A monolithic, airtight foam barrier installed at the roof deck stops radiant heat before it loads your AC, blocks monsoon moisture intrusion, and seals the building envelope against dust and outdoor allergens — a meaningful improvement for families with kids or anyone with allergies. Most Gilbert homeowners we work with see noticeable AC bill reductions in the first SRP cycle after install.
We deliver both open-cell and closed-cell spray foam for residential, commercial, and new-construction projects across Gilbert and the southeast Valley.
The vast majority of our Gilbert work is residential retrofits — taking 2000s and 2010s tract homes from builder-grade thermal performance to genuinely high-performance envelopes.
The single highest-ROI install in Gilbert. Stops radiant heat before it loads your AC.
New construction or existing-home injection foam for older Gilbert homes.
Moisture barrier and pest deterrent for the few Gilbert properties that have them.
The classic Gilbert "always too hot, always too cold" room — solved.
Common in Power Ranch and Seville layouts; eliminates the upstairs heat trap.
We handle Gilbert's commercial buildings across the Heritage District, Cooper Commons, SanTan Village, and the Williams Field/Higley industrial corridors.
Tonnage reduction, controlled interior temperatures.
Quieter buildouts, lower utility bills, better tenant comfort.
Closed-cell foam doubles as a vapor barrier for cold rooms and prep areas.
Many Gilbert custom builders in Whitewing, Circle G, and the Greenfield Lakes area now spec spray foam from day one. We coordinate directly with your GC and trades.
Perfect timing in the build sequence — before drywall, after rough-in.
Most Gilbert homes drop a full ton of AC capacity after foam.
Code compliance and meaningful HERS rating improvements.
Sealed coordination with electrical, plumbing, and HVAC penetrations.
Both foam types have their place, but Arizona's climate skews the choice clearly.
Softer, lower density, excellent sound dampening. Ideal for interior walls, media rooms, and budget-sensitive whole-home installs.
Rigid, higher R-value, vapor barrier, structural rigidity. The right call for nearly every Gilbert attic and crawl space.
Our recommendation for most Gilbert homes: closed-cell foam at the roof deck for attics, paired with open-cell where sound or budget matters more than vapor control.
Spray foam is a two-component polyurethane that ships as separate liquids and reacts at the spray-gun nozzle. Within seconds of leaving the gun, it expands 30 to 100 times its liquid volume, flowing into and sealing every gap, void, crack, and penetration in the surface it's applied to. As it cures (within minutes), it forms a permanent, rigid bond to the substrate.
That expansion behavior is the entire point. Fiberglass batts can only fill the cavities a worker physically pushes them into — they leave the gaps around can lights, plumbing penetrations, electrical boxes, HVAC chases, and the top plate completely unsealed. These hidden air leaks are responsible for the largest share of energy loss in most Gilbert homes, and they're invisible from the attic floor.
Spray foam handles both jobs at once: it insulates against thermal transfer and seals against air movement. That dual function is why a 3" closed-cell application at the roof deck radically outperforms an R-49 fiberglass blanket on the attic floor — even though the math on R-value alone might suggest otherwise.
In Gilbert specifically, this translates to attic temperatures within 10–15°F of your conditioned living space (instead of 60–80°F hotter), AC equipment that cycles less and lasts longer, indoor humidity that stays under control during monsoon season, and a home interior that's measurably cleaner because the building envelope is no longer pulling in dust through hundreds of unsealed openings.
Most Gilbert homes are larger than the metro average — typical projects run between 2,200 and 3,500 sq ft under roof, and many Power Ranch, Seville, and Trilogy properties exceed 4,000 sq ft. That changes the math compared to a typical Tempe install. Here's what to expect:
Open-cell spray foam
$0.45–$0.75 per board foot
Closed-cell spray foam
$1.00–$1.50 per board foot
Typical 2,500 sq ft Gilbert attic (closed-cell, ~3")
$7,500–$11,000
Typical 1,800 sq ft single-story attic (closed-cell, ~3")
$5,400–$8,000
Small 200 sq ft project (closed-cell)
$600–$900
Pricing changes based on existing insulation removal (common in 2000s tract homes), project access, target R-value, and whether walls or just the attic are being treated. Optima provides every Gilbert customer with a fixed, written quote after a free on-site evaluation — no estimate ranges, no surprise change-orders. Fast financing is available on most projects.

We work in every corner of Gilbert — established neighborhoods, master-planned communities, custom-build streets, and commercial corridors.
If you're outside this list but within 30 miles of Tempe, give us a call — we likely cover you.
We've installed spray foam in hundreds of Gilbert homes, and we've refined the process to remove every common pain point homeowners describe with other contractors: surprise pricing, dust everywhere, missed deadlines, vague warranties, hard-sell tactics. Here's exactly how a Gilbert project runs.
Call (480) 568-5602 or fill out our online form. We typically book Gilbert evaluations within 48 hours — same-day for urgent projects.
A senior estimator arrives at your Gilbert home or business with thermal-imaging equipment. We measure your space, identify air-leak hotspots, examine your existing insulation, and discuss what you're trying to fix — energy bills, hot rooms, dust, allergies, monsoon humidity, AC noise, or all of the above.
You receive a detailed, fixed-price proposal in writing — exact scope, foam type, thickness, R-value target, project timeline, total cost, and warranty terms. Take time, ask questions, request changes. We never pressure on the spot.
Our certified Gilbert install crew arrives on schedule, masks every surface, isolates HVAC during application, and installs your foam to the spec'd thickness. Most single-story Gilbert attics complete in one day; larger Power Ranch and Seville two-stories typically run 1.5–2 days. Dust-Free Guarantee applies throughout.
Before we leave, we walk you through every treated area, verify coverage and thickness with a fresh thermal scan, register your lifetime warranty, and schedule your first complimentary performance check for the next cooling season.
Spray foam is a two-part polyurethane material applied as a liquid that expands rapidly into a rigid foam. As it expands, it fills and seals every gap in the cavity it's applied to, then cures into a permanent, airtight insulation barrier. Unlike fiberglass, it stops both heat transfer and air leakage in a single product, making it dramatically more effective in Arizona's climate.
Most Gilbert homeowners spend between $5,400 and $11,000 for a typical attic install with closed-cell foam, depending on home size — pricing runs roughly $1.00–$1.50 per board foot for closed-cell and $0.45–$0.75 for open-cell. We provide a fixed, written quote after a free on-site evaluation. Financing is available.
Yes — and arguably more so in Gilbert than in most U.S. cities. Gilbert summers push attic temperatures 60–80°F above your living space, and that radiant heat drives most of your AC bill. Spray foam stops it at the roof deck, reducing cooling costs significantly and extending HVAC equipment life. Most Gilbert homeowners recoup install costs within several SRP/APS billing cycles.
Properly installed spray foam lasts the lifetime of the building. It does not sag, settle, lose R-value, or absorb moisture the way fiberglass and cellulose do. Optima backs every Gilbert install with a lifetime warranty plus complimentary annual performance checks.
For most Gilbert attics and crawl spaces, closed-cell is the right product — higher R-value per inch, vapor barrier against monsoon moisture, and added structural rigidity. Open-cell is excellent for interior walls, media rooms, and applications where sound dampening or cost savings matter more than vapor control. We recommend the right product for your specific space during the on-site evaluation.
Most single-story Gilbert homes finish in one day. Two-story or larger Power Ranch / Seville homes typically run 1.5–2 days. Commercial projects vary by scope, and we commit to the completion date in your written proposal.
Modern low-VOC spray foam is safe once cured (which happens within minutes of application). During the install itself, our crews use respiratory protection and ventilation, and we recommend occupants vacate the immediate work area for 24 hours as a standard precaution. We handle all prep — masking, drop cloths, HVAC isolation, post-install cleanup — under our Dust-Free Guarantee.
Occupants should plan to vacate the immediate work area for 24 hours during installation. We follow strict safety protocols and provide clear preparation instructions before every Gilbert project — including HVAC isolation, surface masking, and post-install HEPA cleanup under our Dust-Free Guarantee.
Stop overpaying SRP or APS every summer. Book your free on-site evaluation and get a fixed, written quote for your Gilbert home or business — no pressure, no obligation, no surprises.
