Services
Spray Foam Insulation
Spray foam insulation creates an airtight seal in attics, walls, and crawlspaces. This advanced material expands to fill gaps, reducing energy loss by up to 40% while improving indoor air quality. Our team uses closed-cell foam for superior thermal performance and moisture resistance, ensuring long-term efficiency gains for residential and commercial properties.
Energy Audits
Our comprehensive energy audits use blower door tests, infrared imaging, and duct leakage diagnostics to identify efficiency gaps. Technicians analyze 360-degree data points to create customized improvement plans. This diagnostic approach helps homeowners qualify for utility rebates while prioritizing cost-effective upgrades that maximize comfort and savings.
Duct Sealing
Professional duct sealing eliminates air leaks in heating and cooling systems. Using mastic sealant and metal tape, we secure connections in attic ductwork and underfloor systems. This process improves HVAC efficiency by up to 30%, reduces energy bills, and enhances system longevity through proper airflow management and pressure balancing.
Air Sealing
Air sealing services target gaps around windows, doors, plumbing penetrations, and electrical outlets. Our technicians use caulk, spray foam, and weatherstripping to create continuous barriers against air infiltration. This fundamental weatherization step typically reduces energy consumption by 15-25% while improving indoor comfort across all seasons.
Cellulose Insulation
Cellulose insulation made from recycled paper provides excellent thermal performance with environmental benefits. We install this loose-fill material in attics and walls using specialized blowing equipment for uniform coverage. With superior fire resistance and sound-dampening properties, cellulose offers a sustainable alternative to traditional insulation materials while maintaining R-values comparable to fiberglass.

Positive:Professionalism,Punctuality
Two of their professionals (Niki and Squirrel) spent several hours insulating my attic. They worked efficiently and demonstrated great team work. They protected my floors and furnishings and did a very good job of cleaning up when Job was complete. I would recommend them.

Nicholas Sofranec and Xavier OConnor showed up at the scheduled time to remove my existing insulation that was damaged during Hurricane IDA. They worked quickly and efficiently, and cleaned up their mess behind them. After I get some work done in the attic I look forward to Diversified Energy returning to blow in new insulation.

Nicholas Sofranec and Niki Aguillaed were two of the most professional folks who know their job and the solar industry. They were very helpful in explaining the completion process of our solar install along with answering our questions. I would highly recommend this business and if you are lucky enough to get Nick and Nicki you won't be disappointed.

Diversified Energy has been a pleasure to work with. Niki A and her crew (Nick and Byron) did a great job installing insulation on my exterior walls! Their attention to detail really made a difference and sets them apart from other companies. They showed up on time, communicated with me throughout the job, and cleaned up once the work was finished. I will not hesitate to use this company in the future and would recommend them to anyone looking for insulation work.
