Insulation Methods

Learn more about the insulation methods we use to keep homes and businesses comfortable year-round in North Carolina.

High-Performance Spray Foam

The ultimate choice for an airtight seal. Spray foam expands to fill every crack and crevice, providing a superior moisture barrier and the highest R-value per inch available today.

Precision Blown-In Insulation

Ideal for retrofitting existing homes, blown-in insulation fills hard-to-reach spaces, gaps, and cavities to create a more complete thermal barrier. This application helps reduce air movement, improve comfort, and increase energy efficiency without major disruption to your home.

Professional Fiberglass Installation

A classic, reliable choice for temperature regulation and sound dampening. Our modern fiberglass options are fire-resistant and designed to significantly reduce noise transfer between rooms.

FAQs

Frequently asked questions about our insulation services.

What types of insulation do you offer?

We provide a full range of high-performance solutions, including open-cell and closed-cell spray foam, blown-in cellulose and fiberglass, traditional batt insulation, rigid foam boards, and reflective barriers.

Common red flags include:

 

  • Uneven temperatures or “hot spots” between different rooms.
  • A noticeable increase in monthly energy bills.
  • Drafts felt near windows, doors, or baseboards.
    Ice dams form on your roof during the winter.
  • Your HVAC system runs constantly to maintain a comfortable temperature.
  • Smelling mildew or seeing mold in your attic or crawl space.

We proudly serve Central North Carolina, with dedicated teams covering the Piedmont Triad (Greensboro, High Point, Winston-Salem, Burlington) and the Charlotte Metro area (Charlotte, Concord, Huntersville, Mooresville, Gastonia).

Absolutely. We provide free, no-obligation project estimates for all residential and commercial services. You can reach our Greensboro team at 336.296.3423 or our Charlotte team at 704.709.3307.

Our Warranty is limited to the workmanship provided by Seal It Insulation while performing the Work described in the Proposal. The Limited Warranty does not apply to any materials or equipment used in performing the Work. This Warranty is transferable one time within 10 years of the completion of the Work.

Open-cell spray foam is lightweight and excellent for soundproofing and filling large areas, while closed-cell spray foam is much denser, providing a higher R-value per inch and acting as a powerful moisture barrier.

While every project is unique, most residential upgrades (like attic or crawl space insulation) can be completed in a single day. Larger commercial projects or whole-home spray foam applications may take longer depending on the square footage.

Every job we perform is backed by an ACE Audit Report. This digital log tracks the exact chemical ratio used in your home. You will receive a copy of this data to ensure your insulation meets all safety and performance standards.

Unlike many local contractors who rely on guesswork, we differentiate ourselves through Certified Performance and technical transparency:

 

  • The ACE Reporting System: The insulation industry is largely unregulated, but we regulate ourselves using the Akurate (ACE) Monitoring System. While others simply “spray and pray,” our equipment tracks gallon counts, mix ratios, and temperatures in real-time.
  • Data-Backed Proof: Upon completion, you receive an Ace Report—a digital “birth certificate” for your insulation. This data proves your material was applied to exact manufacturer specifications for maximum safety and R-value.
  • Clean Slate Removal: We utilize industrial-grade vacuum systems for insulation removal. This ensures that old, contaminated material is sucked directly into a sealed container outside, keeping your indoor air quality pristine during the process.
  • Local Specialized Expertise: We are deep-rooted in North Carolina, with dedicated teams specifically trained for the unique humidity and climate challenges of the Piedmont Triad and Charlotte Metro areas.
