Spray foam insulation and air sealing are smart investments for McKinney homeowners looking to improve energy efficiency, comfort, and indoor air quality. Whether you need attic insulation, crawl space sealing, wall retrofit foam, or comprehensive air sealing, pricing depends on several factors including project scope, foam type, and accessibility. We're committed to transparent pricing so you know exactly what to expect before we begin work.

| Service | Price | Details |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a 150°F McKinney attic into conditioned space. Ductwork and attic water lines end up inside the envelope, a lesson Winter Storm Uri taught. Every estimate lists the R-value; thickness per pass and board footage. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Two-pound closed-cell foam delivers R-6.5 per inch with its own vapor retarder and real structural stiffening. The right product for metal buildings and barndominiums; pier-and-beam subfloors and any Collin County wall that has to handle both August heat and a hard freeze. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Half-pound open-cell foam air-seals attics and walls at a friendlier price per board foot. Sound dampening between rooms comes with it. We spell out where it belongs, and where a metal building or pier-and-beam floor calls for closed cell instead. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed walls through small drilled ports, no demolition. The retrofit answer for Collin County's 1960s-80s ranches with empty cavities behind brick veneer and for McKinney's historic frame homes. Ports are patched to match. |
| Crawl Space Spray Foam Insulation | From $2,500 | Closed-cell foam on pier-and-beam subfloors stops cold floors in a freeze and holds back humid summer air. McKinney's historic homes sit on them. Moisture and drainage get fixed first, we never spray over a wet crawl space. |
| Rim Joist & Band Joist Spray Foam | From $650 | Band joists; cantilevers and bonus-room floors over garages leak conditioned air at every framing gap. A closed-cell pass seals them for good, the small-ticket job with the fastest comfort payback in a McKinney house. |
| Garage Spray Foam Insulation | From $1,200 | Garage ceilings under bonus rooms and walls shared with the house are foam-sealed against radiant afternoon heat. Workshop conversions are handled the same way. The difference between a storage oven and usable space. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Closed-cell foam is the insulation that stops a Texas metal building from sweating. Barndominiums; shops; pole barns and ag buildings sealed against condensation from Princeton and Farmersville acreage to the warehouses along US 75. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Warehouses; offices; churches and production builders served on schedule. Code-compliant assemblies come with documentation your inspector will actually accept. Phased work keeps your operation running from the US 75 corridor to the Sherman industrial plants. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. Pipe-soaked material comes out too. We also cut out failed spray foam; the job most installers will not touch. Vermiculite gets flagged for testing; never disturbed. |
| Insulation Replacement & Re-Insulation | From $2,800 | The full reset: old material removed; gaps air-sealed; new foam installed to current code R-values. The right call when insulation is flattened; soaked by a frozen pipe or a hail-damaged roof, or when a new roof is going on anyway. |
| Air Sealing | From $650 | Top plates; can lights; chases and attic hatches leak more cooled air than most walls. We seal them before insulating, the step that makes every R-value perform and the cheapest comfort fix in Collin County. |
What Affects the Price
- Project Size and Square Footage : Larger projects typically benefit from better per-unit pricing. Attic and metal building projects are priced per square foot, while closed and open cell foam pricing reflects board feet of material applied.
- Foam Type (Closed Cell vs. Open Cell) : Closed cell foam ($1.20/board ft) offers superior R-value and moisture resistance, making it ideal for basements and crawl spaces. Open cell foam ($0.55/board ft) is more affordable and works well for interior walls where moisture isn't a concern.
- Project Complexity and Accessibility : Tight attics, complicated roof lines, or difficult-to-reach areas require more time and care. Wall injections and rim joist work involve precise application in confined spaces, affecting labor costs.
- Existing Insulation Removal : If old insulation must be removed before new foam is applied, removal costs start at $950. This ensures a clean surface and accurate foam application for maximum performance.

Pricing FAQ
Why does spray foam insulation cost more than traditional fiberglass?
Spray foam provides superior air sealing, higher R-value per inch, moisture resistance, and long-term durability. The upfront cost is offset by lower energy bills, improved comfort, and reduced HVAC strain over time. It's a long-term investment in your home's performance.

Why is crawl space insulation a flat rate starting at $2,500?
Crawl spaces involve setup, safety measures, moisture barriers, and thorough foam application across the entire space. The flat-rate pricing reflects the complete scope of work needed for effective moisture and temperature control.
Are there any hidden fees in your spray foam pricing?
No. Our estimates are transparent and include all labor, materials, and cleanup. We discuss any removal costs upfront so you know the full project cost before we start.
