Atticare Construction is a family-owned business specializing in attic and crawl space services since 2012. The company focuses on what matters most in a home: health, comfort and energy efficiency.

“We truly believe that the attic and crawl space are the best areas to start to improve every home,” says CEO Sean Madar. “We offer a free inspection of the crucial systems of the attic and crawl space so we can help our clients maintain healthy homes with much lower energy bills. In our inspections, we check the insulation, ventilation, roof and HVAC. We also detect and eliminate hazards like rodent activity, mold, and other contaminants to ensure healthier indoor air quality.”

Due to its comprehensive approach, Atticare Construction has helped homeowners and businesses save money on their energy bills, improve their indoor air quality, and raise their property value. The company’s clients are protected by the “Atticare Guarantee”: transparent pricing with no hidden fees, a five-star experience, cleanliness, workmanship and craftsmanship, and financing programs that make every project affordable.
