Professional Duct Sealing in Puyallup & Pierce County
Stop Paying to Heat Your Attic and Crawl Space
Your heating and cooling system is wasting your money right now. Most homes in Pierce County have ductwork with gaps, holes, and poor connections that let 20-40% of conditioned air escape before it reaches your rooms.
You're literally paying to heat or cool your attic and crawl space instead of your home.
Professional duct sealing stops these leaks, lowers your energy bills by 20-30%, and makes your home more comfortable - all without buying expensive new equipment.
Signs Your Ducts Are Leaking Money
High Energy Bills With No Explanation
If your heating or cooling costs keep climbing but nothing else changed, leaky ducts are probably the culprit.
Some Rooms Are Always Too Hot or Too Cold
When ducts leak before reaching certain rooms, those spaces never get the conditioned air they need.
The result? Uncomfortable rooms no matter how you set the thermostat.
Dusty Home No Matter How Often You Clean
Leaky return ducts pull dusty attic or crawl space air into your home. You're breathing that dusty air every day.
HVAC System Runs Constantly
When air leaks before reaching your rooms, your system works overtime trying to reach the thermostat setting - running longer and costing you more.
Visible Gaps or Disconnected Ducts
If you've been in your attic or crawl space, you might have seen gaps where duct sections connect, torn flex duct, or even completely disconnected sections.
How Duct Leaks Cost You Money
The Math
Average Pierce County home spends $1,800-2,400 per year on heating and cooling. If 25% of that air leaks through ductwork, you're wasting $450-600 annually.
Professional duct sealing costs $800-1,500 for most homes and saves $450-600 per year. The work pays for itself in 2-3 years, then continues saving you money for as long as you own your home.
Beyond Just Money
- Uncomfortable rooms
- Poor indoor air quality
- Overworked HVAC equipment (shorter lifespan)
- Wasted energy (environmental impact)
What Professional Duct Sealing Includes
Comprehensive Duct Inspection
We inspect your complete duct system in the attic, crawl space, or basement to identify:
✓Gaps at duct connections
✓Holes or tears in flex duct
✓Disconnected duct sections
✓Poor original installation
✓Inadequate support causing sagging
Professional Sealing
We seal all accessible leaks using professional-grade mastic sealant and foil tape:
✓Mastic: Long-lasting sealant that bonds to ductwork and flexes with temperature changes
✓Foil Tape: Professional HVAC tape for joints and seams (not duct tape - that fails quickly)
Air Leak Detection
We use hands-on inspection techniques to find air leaks throughout your system.
Both supply ducts (carrying conditioned air to rooms) and return ducts (bringing air back to your furnace/AC).
System Testing
After sealing, we verify the repairs improved system performance and airflow.
We seal leaks at:
✓Duct connections and joints
✓Boot connections
(where ducts meet vents)
✓Plenums
(main distribution boxes)
✓Any holes or tears in ductwork

If your ductwork is structurally sound but has leaks at connections, holes, or gaps, sealing is the right solution. This represents 80-90% of homes.
When to Replace
If ducts are crushed, heavily damaged, undersized for your system, or poorly designed, replacement might be necessary.

FAQ
How long does duct sealing last?
When done properly with professional materials (mastic and foil tape), duct sealing lasts 15-20+ years.
That's decades of energy savings from one service.
Can I seal ducts myself?
Some accessible areas you can seal yourself with materials from hardware stores.
However, the most significant leaks are often in hard-to-reach areas in attics or crawl spaces where professional tools and experience make a big difference.
What's the difference between duct sealing and duct cleaning?
Duct sealing stops air leaks to improve efficiency and comfort.
Duct cleaning removes dust and debris from inside ducts.
These are different services addressing different problems.
Most homes benefit more from sealing than cleaning.
Will this fix my uncomfortable rooms?
If uncomfortable rooms are caused by leaky ducts preventing air from reaching those spaces, yes.
Duct sealing will improve airflow and comfort.
If the problem is caused by other issues (inadequate insulation, poor system design), we'll identify that during inspection.
Do you seal the entire duct system?
We seal all accessible duct leaks. Some areas may not be accessible without major construction.
We'll explain what can and cannot be reached during your free inspection.
How quickly will I see energy savings?
Immediately. Your next energy bill should reflect the improved efficiency - typically 20-30% lower than similar months in previous years.
Does this work for both heating and cooling?
Yes. Duct leaks waste energy whether you're heating or cooling your home.
Sealing improves efficiency year-round.
Is mastic better than duct tape?
Yes. Despite the name, actual "duct tape" fails quickly in HVAC applications due to temperature changes.
Professional mastic and foil tape are specifically designed for ductwork and last decades.
