Services
Attic Insulation
Our attic insulation solutions dramatically improve energy efficiency by installing high-performance materials that prevent heat loss in winter and heat gain in summer. We use advanced blown-in cellulose and spray foam options that meet R-value requirements while qualifying for utility rebates. Proper attic insulation reduces HVAC strain and maintains consistent indoor temperatures year-round.
Attic Air Sealing
We identify and seal attic air leaks using specialized diagnostic tools to prevent conditioned air escape and outdoor air infiltration. This process involves sealing gaps around penetrations, ductwork, and framing to create an airtight barrier. Air sealing improves energy efficiency, reduces drafts, and prevents moisture-related issues in attic spaces.
Crawlspace Encapsulation
Our crawlspace encapsulation creates a controlled environment by sealing moisture entry points and installing vapor barriers. This process prevents mold growth, improves indoor air quality, and enhances structural integrity. Encapsulated crawlspaces contribute to overall home energy efficiency by eliminating cold floor issues and reducing HVAC workload.
Rim Joist Sealing
We apply spray foam insulation to rim joists to seal air leaks between foundation walls and first-floor framing. This critical area often accounts for significant energy loss. Our sealing process improves thermal performance, prevents pest entry, and reduces noise transmission while maintaining structural integrity in both new and existing constructions.
Energy Audits
Our comprehensive energy audits use thermal imaging and blower door testing to identify energy waste sources. We provide detailed reports showing problem areas and recommended solutions with projected savings. The audit process helps prioritize improvements and qualify for utility rebates, giving homeowners a clear roadmap for achieving optimal energy performance.

I can't say enough positive things about this company; they are definitely best-in-class. Over the past 2 years we've asked them complete 3 different projects. 1) add blown-in insulation and foam seal our attic; 2) foam seal our basement; 3) add blown-in insulation for soundproofing. First, they are very competitively priced. Also, they always arrive on-time, are extremely professional, and quickly respond to my many questions. During the estimate phases, Ryan always does a great job explaining, in layman's terms, the benefits of different options. DJ, Javon, Christian, and Kike

I reached out to Ryan at NetZero Insulation to address some insulation issues with our attic and crawlspace areas, and he responded quickly and professionally. Proposal was provided the next day and was very thorough and reasonable. Communication has been great even throughout the holidays. Would highly recommend NetZero Insulation for any insulation needs.

I can't say enough good things about Ryan and his team. Absolute class act. I had them install a vapor barrier in my basement and add more insulation in my attic and add spray foam. It's been a few years since they installed everything and the house has been noticeably warmer in the winter and cooler in the summer. I have no doubt we're saving a lot of money on our electric bills as a result. And recently I noticed the vapor barrier was coming off the wall in an area in the basement where some other workmen had walked on it, and Ryan and his team came back and fixed it for no

NetZero sealed and added insulation to the attic and encapsulated the crawl space in one day. Ryan the owner was there to get the job started and the crew knew what needed to be done and had everything required. I would definitely recommend NetZero to anyone looking to make their home more energy efficient.

Ryan and his crew at NetZero were amazing! They installed insulation in our attic. Our house was built it 1901 and was very drafty. With all of the work that NetZero did. We are able to keep our home comfortable. It stays cooler in the summer and we're positive it will stay warmer in the winter.
Ryan explained what our house was needing and the solution options we had for fixing it. He is very knowledgable and shared his experiences. We would recommend this company to anyone!

We solicited bids from two contractors to seal and add insulation to our attic spaces. Ryan at NetZero, and all his employees, were professional, knowledgeable, efficient, and considerate. NetZeros quote was detailed, comprehensive, and clearly explained, and his price was the best. Ryan allowed us to pick and chose work items from his quote that we felt best met our needs and budget. You will enjoy working with Ryan and his team!

Professional operation. Owner was onsite for most of the project. Ryan and his whole crew was hard-working and extremely respectful of us, and our home. They seem to take pride in doing quality work. Very responsive to all communication prior to the project. Highly recommend.
