Houston, TX Air Duct Cleaning Service & Insulation | Atticair
The cost to spray foam insulation for a 1000 sq ft area typically ranges from $1,500 to $4,000, with an average around $2,750. This wide variation depends heavily on the foam type and project specifics. Open-cell foam, which is less dense and has a lower R-value per inch, usually costs $0.44 to $0.65 per board foot, making it the more economical choice. Closed-cell foam, offering a higher R-value, superior moisture resistance, and structural strength, costs significantly more, generally $1.00 to $1.50 per board foot. The final price is also influenced by the desired insulation thickness (R-value), the complexity of the installation (like attic obstructions or wall cavities), your geographic location, and the contractor's labor rates. For an accurate estimate, it is essential to get a professional assessment from a qualified insulation contractor like Atticair, as proper installation is critical for performance and safety.
Insurance companies may hesitate to insure homes with spray foam insulation due to concerns over improper installation. If installed incorrectly, this insulation can trap moisture within walls, leading to hidden rot, mold growth, and structural damage. Some older formulations also posed fire safety risks if not adequately covered with a thermal barrier. Insurers view these potential long-term, concealed damages as significant liabilities. However, many providers will offer coverage if the installation is performed by a certified professional and includes proper ventilation detailing and a fire-rated coating. Homeowners should always obtain documentation and certification from the installer to present to their insurance carrier.
The cost to spray foam a 40x60 building (2,400 sq ft of floor space) varies significantly based on the type of foam, desired R-value, and regional labor rates. For closed-cell spray foam, which provides a high R-value per inch and acts as an air and vapor barrier, you can expect a price range of $1.50 to $3.00 per board foot. For a building with an average ceiling height, total costs often fall between $4,500 and $12,000. Open-cell foam, which is less expensive at $0.44 to $0.65 per board foot, would typically cost $2,000 to $4,000 for the same structure but requires more thickness for equivalent insulation value. Key factors affecting the final quote include the condition of the building envelope, local code requirements, and the complexity of the framing, which is why a professional on-site assessment is always recommended for an accurate estimate.
The cost to spray foam a 24x24 garage (576 sq ft of floor area) typically ranges from $1,500 to $3,500, with an average around $2,500. This wide range depends on several key factors. The type of foam is a primary cost driver: open-cell foam is less expensive ($1.50 to $2.50 per board foot) but provides a lower R-value per inch, while closed-cell foam is more costly ($3.00 to $5.50 per board foot) but offers a superior air and moisture barrier with a higher R-value. The required thickness (R-value), the complexity of the garage structure (e.g., ceiling height, obstructions), your geographic location, and the contractor's labor rates all significantly influence the final price. For a standard two-car garage with walls and a ceiling, you are generally insulating both the wall cavities and the roof or ceiling assembly, which is calculated in board feet (area multiplied by thickness). Always obtain multiple detailed quotes from licensed and insured professionals. A proper spray foam application not only improves comfort but also enhances energy efficiency and structural integrity, making it a valuable long-term investment for the space.
