Insulation and air sealing work together to improve comfort, reduce energy waste and protect your home from seasonal extremes. By keeping conditioned air inside and blocking drafts and heat loss, these upgrades help lower your energy bills and create a more stable, efficient indoor environment.

We offer a full range of solutions to make your home more efficient, comfortable and protected. Installed to the highest standards by our dedicated team.

Spray Foam Insulation

A construction worker wearing a protective mask, gloves, and a plastic suit is spray foam insulation into a wooden wall frame.

Spray foam seals air leaks and insulates in one step ideal for attics, crawl spaces, rim joists and hard-to-reach areas. We use spray foam for its durability, moisture resistance, and high R-value. Every application is done cleanly and precisely, meeting utility program standards without shortcuts. Whether you're prepping for a rebate or just want a tighter, more efficient home, spray foam gets results.

Cellulose Insulation

Blown-in cellulose insulation is a fast, clean way to boost comfort and reduce energy waste. Made from recycled paper and treated for fire and mold resistance, it is safe for people and pets. It is installed through small holes in the exterior siding, patched cleanly with no disruption inside. The upgrade delivers lasting results without mess or teardown.

Fiberglass Insulation

Fiberglass remains a reliable option for open cavities and attic spaces. Installed in batts or loose-fill form, it offers solid thermal performance and cost-effective coverage. Our crew installs fiberglass cleanly and professionally, with no shortcuts and no mess left behind.

Insulation Removal

Old insulation can trap moisture, dust and allergens… and it often hides mold or pest damage! We remove outdated material safely and thoroughly, prepping the space for a clean, efficient upgrade. No mess, no lingering debris and no overlooked details.

Air Sealing

We seal the gaps that waste energy from top to bottom. The team targets crawl spaces, basement edges (rim joists), wall interiors and other leak-prone areas to stop drafts and improve comfort. Every seal is done with care and precision, using the right materials for each space. The result is a tighter, more efficient home with fewer temperature swings and lower energy bills.

Mold Remediation

Mold threatens air quality and damages building materials. NetZero removes it safely and thoroughly, using protective gear and targeted treatments to eliminate mold at the source. We follow containment protocols and proven methods, not quick sprays or coverups, to protect your home and your health.

Most homes in Rhode Island are under-insulated, and it shows in your energy bills.

NetZero delivers clean, targeted upgrades that improve comfort, reduce waste and protect your home from seasonal extremes.
