 Trustindex verifies that the original source of the review is Google. I can’t say enough about the positive experience I had with 5CEnergy. Neri and his team were very respectful of my home, and kept me in the loop throughout the entire installation process. I had three things done through the MassSave program - attic insulation, an exhaust pipe routed through the roof, and door stripping/sweeps added to two doors. I felt extremely confident in the work because of the excellent communication; Neri came to get me a few times to show me the progress and gave me options on how I wanted the work to be done. For such a messy job like insulation, my house was spotless when they left. I would absolutely use 5CEnergy again, as well as recommend them to a friend. Please thank Neri and his team for me!

 Trustindex verifies that the original source of the review is Google. Cliff the chief supervisor arrived 5 minutes early with his worker Juan both conducted themselves as perfect gentleman worked efficiently and did a complete walk-through before and after cleanliness was beyond my expectations, they swept up after themselves left my basement floor. I think Cleaner than that when they started, Cliff explained everything that they were going to do and then afterwards brought me back downstairs to make sure that cleanliness was up to my expectations and was there anything else that they could do and explained everything that had been done and if everything was OK and was there anything else that they could do? I would highly recommend 5C energy to anybody.
Thank you 5C energy for making my home more energy efficient!! You’ve got a great team!

What You Can Expect

Preparing Your Property

We carefully prepare attic access points, especially in cramped Tatnuck-era knee walls, ensuring debris is contained before sealing bypasses.

Installing High Quality Materials

Our attic insulation services include blown-in cellulose insulation, fiberglass insulation, and spray foam systems designed to reduce heat loss and improve thermal control.

Curing and Ventilation

After installation, we confirm attic airflow and ventilation are balanced. Proper ventilation helps prevent moisture buildup and uneven insulation performance.

Why Proper Insulation Matters?

Attic insulation plays a major role in reducing heat loss during Worcester winters. Without proper insulation, heated air escapes through the attic, forcing HVAC systems to work harder and increasing utility costs.

Proper attic insulation also helps stabilize second-floor temperatures and reduce moisture issues caused by seasonal humidity changes. According to the U.S. Department of Energy, attic insulation and air sealing are among the most effective ways to improve residential energy efficiency.
