Why Duct Sealing is Critical for Pearland Homes
Your ductwork is supposed to deliver conditioned air efficiently throughout your home. But in reality, most duct systems leak significantly—wasting 20-30% of heated or cooled air into attics, crawlspaces, and walls where it does nothing but cost you money.
In Pearland's climate where air conditioning runs 8-9 months annually, these leaks translate to hundreds of dollars wasted every year. Professional duct sealing stops the leaks, dramatically improving comfort while reducing energy bills.
Common Duct Leak Locations
Connection Points
Where duct sections connect, joints often separate or were never properly sealed during installation, allowing significant air loss.
Register Boots
Connections between ductwork and ceiling/floor vents frequently have gaps allowing air to escape into wall cavities.
Trunk Line Seams
Main duct trunks develop leaks along seams as buildings settle and materials age, especially in attic installations.
Air Handler Connections
Where ductwork connects to HVAC equipment, improper installation or deteriorated seals create major leak points.
Branch Take-Offs
Spots where smaller ducts branch from main trunks often lack proper sealing, particularly in older installations.
Attic Penetrations
Locations where ducts pass through attic floors or walls frequently have unsealed gaps allowing massive air loss.
How Duct Leaks Waste Money and Comfort
Understanding leak mechanics explains why professional sealing delivers such dramatic improvements:
- Attic Air Loss: Cooled air escaping into 140°F attics wastes energy while hot attic air gets sucked into ductwork, forcing AC to work harder
- Pressure Imbalance: Leaks create negative pressure pulling hot, humid outdoor air into your home through cracks and gaps
- Uneven Temperatures: Rooms farthest from AC unit don't receive adequate airflow due to leaks reducing system pressure
- Extended Runtime: HVAC systems run longer trying to compensate for lost capacity, increasing wear and energy costs
- Humidity Problems: Leaky returns pull humid air from attics and crawlspaces, making indoor humidity control difficult
- Increased Bills: Average leaky duct system wastes $500-800 annually in Pearland's climate with year-round cooling needs
Professional Duct Sealing Methods
We offer two proven sealing approaches based on your system's needs:
- Manual Sealing: Accessible leaks sealed with mastic compound and metal-backed tape. Permanent, durable solution for visible connections. Includes all accessible joints, seams, and connections throughout system
- Aeroseal Technology: Revolutionary process seals leaks from inside using polymer particles. Reaches inaccessible areas impossible to seal manually. Computer-controlled process measures exact leak reduction. Proven to seal up to 90% of duct leakage. Ideal for finished buildings where ducts are hidden
- Combination Approach: Manual sealing of accessible areas combined with Aeroseal for hidden sections provides most comprehensive sealing
Our Duct Sealing Process
Comprehensive leak detection and sealing ensures maximum results:
- Initial Assessment: Inspect accessible ductwork identifying visible damage, disconnections, and major leak points
- Blower Door Testing: Measure total home air leakage establishing baseline for improvement verification
- Duct Pressure Testing: Quantify exact duct leakage percentage using specialized equipment
- Leak Mapping: Create detailed map of leak locations and severity throughout entire duct system
- Manual Sealing: Seal all accessible connections, joints, and penetrations with professional-grade mastic and tape
- Aeroseal Application: If applicable, seal remaining inaccessible leaks using Aeroseal polymer technology
- Verification Testing: Re-measure duct leakage confirming leak reduction and performance improvement
- Documentation: Provide before/after test results showing exact improvements achieved

Frequently Asked Questions
How much does duct sealing cost in Pearland?
Duct sealing costs $300-$1,200 depending on home size and leak severity. Standard homes average $600-$800 for manual sealing. Aeroseal technology costs $1,000-$1,500. Price includes leak detection, sealing, and verification testing. ROI typically achieved within 2-3 years through $500+ annual energy savings.
How do I know if my ducts need sealing?
Signs include high energy bills, uneven room temperatures, excessive dust, poor airflow from vents, rooms that won't reach desired temperature, and HVAC running constantly. Professional leak detection with pressure testing identifies exact locations and severity of leaks throughout your duct system.
What is Aeroseal and how does it work?
Aeroseal is patented technology that seals duct leaks from inside. Polymer particles are forced through ductwork under pressure. Particles accumulate at leak points, gradually sealing them. Computer monitors process showing exact leak reduction. Reaches inaccessible areas impossible to seal manually. Proven to eliminate up to 90% of duct leakage.
