Project Overview
Our team at Zavza Seal completed an insulation upgrade project in East Northport, NY with the goal of improving energy efficiency and making the home more comfortable throughout the year. The property had weak insulation, uneven temperature control, and noticeable air leaks that were affecting overall comfort and energy use.
Problem
The homeowner was dealing with several issues inside the home. Cold drafts were coming through the exterior walls, especially during colder months. The attic insulation was old, thin, and no longer effective, which caused heat to escape easily.
The home was also losing energy through poorly sealed areas around windows, which made heating and cooling systems work harder than needed. The attic insulation was only about 5 inches thick and in poor condition, which is not suitable for New York weather conditions. As a result, energy bills were higher and indoor comfort was inconsistent.
Solution
To fix these issues, our team created a two-part insulation improvement plan that targeted both the exterior walls and the attic.
For the exterior walls, we carefully removed a small section of siding to reach the wall cavities. We then drilled access points between the studs and installed dense packed cellulose insulation. This allowed us to improve the insulation value to R-19 without changing the appearance of the home. We also properly sealed the window area to prevent air leakage before reinstalling the siding to its original condition.
For the attic, we upgraded the insulation across approximately 1,200 square feet. We reinforced the attic floor where needed and installed a protective netting system over the joists. After that, we blew in dense packed cellulose insulation over the existing material, bringing the attic up to an R-50 insulation level. This significantly improved the thermal barrier between the living space and the attic.
About the Insulation Used
The insulation used in this insulation project in East Northport, NY is environmentally friendly and designed for long-term performance. It is fire resistant, meets Class 1 fire rating standards, and provides strong resistance against moisture and water damage. It also helps reduce outside noise and improves indoor air quality. The material is Gold certified and supports a healthier living environment.
Results
After the upgrade, the home experienced a noticeable improvement in comfort. Drafts were reduced, indoor temperatures became more stable, and the home retained heat and cool air more effectively. Energy loss through the attic and walls was significantly reduced, and the homeowner also noticed less outside noise entering the home. Overall, the property is now much more energy efficient and comfortable year-round.
