Services
Attic Insulation
Our attic insulation services use cellulose material to enhance energy efficiency. We upgrade existing insulation to reduce heating bills by 20% and cooling costs by 10%. The loose-fill application creates complete coverage in attics and wall cavities. This solution works effectively for both retrofitting older homes and new construction projects.
Spray Foam Insulation
Professional spray foam application for residential and commercial buildings. We install open and closed-cell foam in walls, rim joists, and attics. This versatile material outperforms traditional insulation by creating an air barrier while maintaining thermal efficiency. Ideal for new construction and remodeling projects of all sizes.
Crawl Space Insulation
Specialized crawl space insulation using spray foam and vapor barriers. We seal moisture entry points while insulating foundation walls. This process creates conditioned spaces that maintain floor warmth and prevent humidity-related issues. Combines insulation with long-term moisture control solutions.
Air Sealing
Comprehensive air infiltration control through gap sealing and penetration management. Our infrared imaging identifies hidden leaks around windows, doors, and utility penetrations. We address these vulnerabilities before insulation installation to maximize energy savings and maintain indoor comfort levels year-round.
Poly Jacking
Polyurethane foam injection for concrete lifting and leveling. We repair uneven driveways and sidewalks by filling voids beneath surfaces. The moisture-resistant foam provides permanent stabilization through small 5/8" drill holes. No demolition required for immediate use after completion.

7 years ago A+ Insulation re-insulated my house. After a long weekend away, I came home to realize my furnace had gone out (and ended up getting a new furnace). Due to the great insulation job A+ Insulation did over 7 years ago, my house only got down to 50 when one of those 4 days my furnace was out the high was in the single digits! Fantastic job all these years later!!!

Joe could not have been more thorough. He was personable, honest, and professional. We asked him to look at our insulation based on an inspection on a home we were selling. He corrected the issue and was very reasonable. I highly recommend A-Plus Insulation.
