Air sealing works hand-in-hand with insulation to create a complete thermal envelope, preventing energy loss and improving the overall efficiency of your HVAC system. Without proper sealing, even the best insulation won’t perform as intended. By addressing leaks and gaps in your building envelope during a new construction project, you can:
- Ensure you pass your blower door test
- Minimize drafts and temperature fluctuations
- Improve indoor air quality by reducing the infiltration of allergens, dust, and pollutants
- Lower heating and cooling costs by maximizing energy efficiency
Preferred Builder Resources offers residential and commercial air sealing services for new construction projects throughout Alabama and Mississippi’s Gulf Coast areas and Florida’s Emerald Coast. We also work directly with builders and contractors to offer these services and many more!
Air Sealing Services
Air leaks in your home’s building envelope—found around windows, doors, attics, and crawl spaces—can make it difficult to maintain a comfortable indoor environment. Our air sealing services target these problem areas, preventing outside air from infiltrating your home.
How Air Sealing Works:
- We identify air leaks using advanced diagnostic equipment such as blower doors.
- Gaps and cracks are sealed using high-performance caulks, foams, and other materials.
- Special attention is given to hard-to-reach areas, such as plumbing and electrical penetrations.
Benefits of Air Sealing:
- Reduces drafts and cold spots, improving indoor comfort.
- Enhances insulation performance by preventing air movement through walls and ceilings.
- Lowers heating and cooling bills by minimizing energy loss.
Air Sealing Is Ideal For:
- New homes to create an airtight building envelope during construction.

Pass Your Blower Door Test with Professional Air Sealing
Proper air sealing is key to passing blower door tests—yet many builders underestimate its importance, resulting in failed inspections and costly delays. At Preferred Builder Resources, we can seal both pre- and post-drywall to deliver a reliably tight building envelope, ensuring you meet energy efficiency standards and meet code requirements on your project.

How Air Sealing Works Together with Insulation
Insulation and air sealing are a killer combination for energy efficiency. When these components work together, they create a fully sealed and insulated home that delivers maximum comfort and savings.
- Insulation provides a thermal barrier to resist heat flow.
- Air sealing eliminates gaps and cracks, preventing unconditioned air from entering your home.
Together, these services create a healthier, more comfortable, and energy-efficient living environment. If you’re starting fresh with a new construction project, our team ensures all systems work cohesively for optimal results.
