Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Murrieta
We’re the crew Hollis Air Duct Cleaning dispatches from our Inland Empire office to handle Duct Sealing in Murrieta and the surrounding communities. If your vents are blowing dust, your rooms aren’t heating or cooling evenly, or your energy bills have climbed without explanation, there’s a good chance your ductwork is leaking air into the attic or crawlspace. We seal ducts in Murrieta homes built in the 1980s through today, and we know the specific problems this city’s housing stock and climate create. Call us at (361) 326-5060 for a free estimate. We’ll show up in the window we promised, price the job in writing before we touch anything, and back it with our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Murrieta’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing team serves Murrieta under The Garrison Standard. That means written prices, written guarantees, and technicians who arrive uniformed, background-checked, and on time. Murrieta homeowners don’t need another company that quotes low over the phone and doubles the price at the door. We price by the system, not by the vent, and that number is locked before work starts.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. When you call (361) 326-5060, you talk to someone who can schedule your Murrieta appointment or answer questions about what duct sealing actually involves.
We know Murrieta’s neighborhoods. From the master-planned communities near California Oaks Road to the older homes around Old Town Murrieta and the newer builds in the Laurelwood area, we’ve worked in attics with flexible ductwork, rigid metal trunk lines, and everything in between. That local familiarity matters because the duct problems in a 1995 home off Jefferson Avenue aren’t the same as those in a 2018 build near Los Alamos Road.
Air Duct Sealing in Murrieta
Air Duct Sealing in Murrieta means finding and closing the gaps, loose joints, and failed sealant in your home’s ductwork so conditioned air reaches your rooms instead of leaking into the attic. Our crew uses mastic sealant and metal-backed tape at connections, then verifies the seal with pressure testing where appropriate. A typical whole-house duct sealing job in Murrieta runs $450 – $850 depending on system size, attic accessibility, and how many connections need attention. Most single-family homes in Murrieta fall in the $550 – $700 range.
When Murrieta Homes Need Sealing
You’ll know it’s time when rooms stay hot while others freeze, when dust blows from vents even after cleaning, or when your HVAC runs constantly without catching up. In Murrieta’s long, dry summers, cracked sealant around flexible duct connections is common. The Santa Ana winds and temperature swings in attic spaces harden mastic and tape over time.
What the Job Actually Looks Like
We access the ductwork through attic hatches or crawlspace openings, inspect each joint and connection, remove old failing tape, apply fresh mastic, and secure connections with proper metal-backed tape. We don’t use standard duct tape; it fails. For homes near the Santa Rosa Plateau or in the path of seasonal wildfire smoke, sealing also keeps outside contaminants from getting pulled into leaky return ducts.
Duct Sealing Services in Murrieta
Duct Sealing Services in Murrieta cover the full range of residential ductwork repair and sealing, from spot repairs at loose register connections to complete system resealing after construction damage or wildfire smoke infiltration. We also handle partial replacements of crushed or disconnected flexible ductwork, which we find frequently in Murrieta attics where original builder-grade materials weren’t secured properly. A targeted repair at a single connection might run $180 – $280; full system sealing for a larger home with multiple zones can reach $900 – $1,200.
Construction Debris and Newer Homes
Because Murrieta’s housing stock is dominated by master-planned subdivisions built from the 1980s through the 2000s with flexible ductwork run through attic spaces, our crew routinely finds construction dust, drywall dust, and tape debris still sitting in supply and return ducts of homes that are only a few years old. Many Murrieta homeowners schedule their first Murrieta Dryer Vent Cleaning or duct cleaning far later than the construction debris actually warrants. Sealing during that first service prevents that debris from circulating indefinitely.
Wildfire Smoke and Seasonal Stress
After major wildfire events in the nearby Santa Rosa and San Jacinto mountains, Murrieta technicians see a surge in calls as ash and smoke infiltrate home HVAC systems. Leaky ducts pull that contaminated attic air straight into your living space. Sealing before fire season starts is preventive maintenance that pays off when the smoke arrives.

Trusted Brands We Service in Murrieta
Our Murrieta crews carry professional-grade equipment from Rotobrush, Nikro, and Guardsman on every van. Rotobrush camera systems let us show you exactly what’s inside your ducts before we seal anything. Nikro negative-air machines maintain proper containment during the job. For sealing materials, we use Guardsman mastic and metal-backed tapes rated for the temperature swings Murrieta attics experience. We don’t show up with hardware-store duct tape or generic caulk. The products we use are the same ones commercial HVAC contractors specify, and we explain what each one does while we’re working in your home.
Common Duct Sealing Problems We See in Murrieta Homes
- Builder-grade flexible ductwork with loose joints. Homes in Murrieta subdivisions from the 1990s through 2010s often have flexible duct connections at the air handler and registers that were never properly sealed with mastic. Air leaks into the attic, and dust bypasses the filter entirely.
- Drywall dust and construction debris in newer builds. We were called to a home in the Laurelwood subdivision in Murrieta, where the homeowner had moved into a newly built house and noticed a persistent drywall-dust smell every time the AC kicked on. Using a Rotobrush camera inspection, we found drywall dust and construction debris caked along the flexible ductwork in the attic, and we performed source removal with negative pressure and HEPA filtration to clear the supply and return ducts. After sealing several leaky connections at the air handler and registers with Guardsman mastic, the dust smell disappeared and the system’s airflow improved noticeably.
- Cracked sealant from Murrieta’s dry heat and Santa Ana winds. The long, dry summers and temperature extremes in local attics dry out mastic and adhesive tapes. What sealed fine five years ago may be brittle and leaking today, especially on west-facing homes that bake afternoon sun.
- Wildfire smoke infiltration through unsealed returns. When smoke events push ash and particulate into attic spaces, leaky return ducts act like vacuum lines, pulling that contamination into your HVAC system and distributing it room to room.

FAQs About Duct Sealing in Murrieta
Yes, probably. Builder-grade flexible ductwork in Murrieta’s newer subdivisions often has connections that were taped but never properly mastic-sealed, and construction debris may still be inside the system. We find drywall dust and loose tape in homes less than ten years old regularly. Call (361) 326-5060 and we’ll inspect it at no charge.
Wildfire smoke from the Santa Rosa and San Jacinto mountains pushes ash and fine particulate into Murrieta attics, and leaky ducts pull that contamination directly into your HVAC system. Sealed ducts block that pathway. If you’ve noticed dust or odor after smoke events, your ducts are likely leaking. We can test and seal them before the next season.
It can, especially when combined with proper duct cleaning. New construction in Murrieta’s master-planned communities often leaves drywall dust and debris in flexible attic ductwork. Sealing prevents that debris from recirculating and stops the system from pulling in new dust from the attic through leaky connections. We document everything with camera inspection so you see the source.
We seal with Guardsman mastic and metal-backed tape, inspect with Rotobrush camera systems, and maintain containment with Nikro negative-air equipment when cleaning is part of the job. These are professional-grade tools, not hardware-store supplies, and we explain what each one does while we’re in your home.
If your vents blow visible dust right after cleaning, or if some rooms never reach the thermostat setting while others over-condition, you likely have leaks that cleaning alone won’t fix. We inspect with a camera first and show you the condition of your connections. Sometimes Murrieta homes need both. We’ll tell you exactly what we found and give you a written price for either service or both. Call (361) 326-5060 to schedule.
