If you searched for duct sealing Lawrenceville GA, you’re probably dealing with high energy bills, uneven room temperatures, or a technician recommended it during a visit. This guide covers the real signs, cost, and energy savings you can expect. Call 678-235-3388 for a written quote.
What Is Duct Sealing?
Duct sealing closes gaps, holes, and poorly connected joints in your ductwork using mastic sealant or specialized tape, preventing conditioned air from leaking out before it reaches your rooms. It’s different from duct cleaning, which removes debris rather than fixing air leaks — many Lawrenceville homes benefit from both.
Signs You Need Duct Sealing
- Some rooms are noticeably hotter or colder than others
- Higher energy bills without a clear explanation
- Visible gaps or disconnected sections in accessible ductwork (attic, crawlspace)
- Dust or musty smells from areas near ductwork, like a crawlspace
- The HVAC system runs constantly but struggles to reach the set temperature
