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 Sansom Park
Your ducts are leaking. In Sansom Park, that means conditioned air escaping into your attic or crawl space, utility bills climbing every month, and rooms that never reach the temperature you set. Duct sealing closes those gaps permanently using mastic sealant and metal-backed tape applied at every joint, connection, and penetration. Most Sansom Park homes we seal see a 15 – 25% drop in heating and cooling costs within the first billing cycle.
We’re the Duct Sealing in Sansom Park crew from Hollis Air Duct Cleaning, and we know this city’s housing stock inside out. Dispatch and scheduling run through our Dallas-Fort Worth office, but our technicians live and work in Tarrant County neighborhoods like yours. That matters when you’re trying to schedule around a workday and need someone who actually shows up inside the window. Call (361) 326-5060 and you’ll reach a live person, not a voicemail maze.
Sansom Park sits in the heart of the Mid-Cities corridor, and the homes here tell a specific story. Most were built between the 1940s and 1970s, with original galvanized metal ductwork that’s now pushing 50 – 80 years of service. Those metal joints have loosened. The internal rust has created pinholes. Retrofit flex duct sags between joists, creating low spots where air pools instead of flows. Our Duct Sealing team addresses each failure point with methods matched to the material, not a one-size-fits-all approach.
Why Hollis Air Duct Cleaning Is Sansom Park’s Preferred Duct Sealing Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Tarrant County markets like Sansom Park is built on operational specifics, not advertising claims. Technicians arrive uniformed, background-checked, and equipped with professional-grade tools from Rotobrush and Nikro. The price is written down before any work starts. The site is left clean. These aren’t slogans for us; they’re requirements under The Garrison Code that governs every job.
Our 365-Day Done Right Promise applies to every duct sealing job in Sansom Park. If the seal fails, the airflow doesn’t improve, or you find we missed a joint, we return and make it right at no charge. That includes a free second visit, not a negotiated callback. Competitors in this trade rarely put a full year in writing.
Phones are answered by a live person 24 hours a day, 7 days a week. When you’re staring at a winter heating bill that’s $80 higher than last year, or a summer electric bill that never seems to drop, you don’t want to leave a message and hope someone calls back Tuesday.
Duct Repair in Sansom Park
Duct Repair in Sansom Park addresses the physical damage that sealing alone cannot fix: crushed flex runs, disconnected trunk lines, corroded metal that has rusted through, and sections chewed by rodents common to the pier-and-beam foundations throughout the area. A typical repair runs $280 – $520 depending on material length and accessibility, with most jobs completed in a single visit.
Metal Duct Restoration
Original galvanized steel ducts in Sansom Park’s post-war ranches often suffer from internal rust that flakes off and restricts airflow. We cut out corroded sections and splice in new galvanized or insulated flex, then seal every joint with mastic. The result is restored capacity without the cost of full replacement.
Flex Duct Replacement
Sagging flex duct between joists is a constant issue in homes near Lake Worth and along Roberts Cut Off Road. We suspend new flex properly, eliminate the low spots where debris collects, and insulate to R-6 or R-8 depending on attic conditions. This stops the trapped-air problem that makes back rooms feel stale.
Air Duct Sealing in Sansom Park
Air Duct Sealing in Sansom Park is the precision work of closing every leak point in your distribution system without replacing intact ductwork. We pressurize the system, measure leakage with a duct blaster, then apply mastic sealant and metal-backed tape at joints, boots, and plenum connections. A typical whole-system seal runs $1,800 – $3,200 for a single-zone residential system, with exact pricing determined by duct count, accessibility, and leakage severity measured during your free estimate.
Leak Detection and Measurement
We start every sealing job with a pressure test. The duct blaster gives us a CFM25 number, which tells us exactly how much air you’re losing to unconditioned spaces. In Sansom Park, we regularly see homes leaking 30 – 40% of their airflow before sealing. After our work, that number typically drops below 10%.
Mastic Application Standards
Water-based duct mastic, not duct tape, is what creates a permanent seal. We brush it into every joint, allow proper cure time, and verify with a second pressure test. The black soot from Loop 820 traffic that permeates local homes can’t penetrate a properly sealed system, and your filter lasts longer because it’s not loading up with road dust.
Trusted Brands We Service in Sansom Park
Our equipment roster includes professional-grade tools from Rotobrush, Nikro, and Abatement Technologies, plus filtration products from Honeywell, Aprilaire, and Guardsman. For Sansom Park homeowners, this means we don’t order parts from a catalog and wait a week. We stock mastic, metal-backed tape, galvanized fittings, and insulated flex in diameters common to the 1,000 – 1,400 square foot ranches that dominate this market. When we find a crushed return duct under your pier-and-beam home, we fix it that day, not after a supply run to Dallas. Fast turnaround matters when your AC is running constantly through a July stretch of 100-degree days.
Common Duct Sealing Problems We See in Sansom Park Homes
- Loose joints in original galvanized trunk lines. The metal ductwork installed in 1950s and 1960s Sansom Park ranches was sealed with fabric tape that has dried and failed. We find gaping separations at every branch connection, dumping conditioned air directly into attics that reach 140°F in August.
- Sagging flex duct in pier-and-beam crawl spaces. Retrofit flex installed in older homes wasn’t properly suspended, creating low spots where humid North Texas air condenses. This moisture breeds mold and collapses the inner liner, cutting airflow to back bedrooms by half.
- Return-air ducts drawing in diesel exhaust near railroad tracks. Homes along the western edge of Sansom Park, near the BNSF line, have return plenums with cracked seams or missing end caps. Instead of recirculating indoor air, these systems pull in locomotive exhaust, leaving that stubborn black film on filters and registers that standard vacuuming won’t remove.
- Oversized gaps around ceiling boots and wall penetrations. The drywall cuts in older homes were rough, and installers often left 1 – 2 inch gaps around metal boots. These bypasses send conditioned air into wall cavities where it does nothing for comfort but plenty for your electric bill.
Pricing for Duct Sealing in Sansom Park, TX
Whole-system duct sealing in Sansom Park typically runs $1,800 – $3,200 for a single-zone residential HVAC system. Partial sealing of a specific problem area, such as a leaking trunk line or disconnected branch, ranges from $280 – $650. Factors that move the price: accessibility (crawl space vs. attic), duct material type (metal requires more labor than flex), and the initial leakage rate measured during our free pressure test.
We do not quote per-vent pricing. That structure invites bait-and-switch tactics we’ve all heard about in this industry. Instead, we give one flat price per system, agreed in writing before any work starts. The price does not move at the door, and it does not grow because we “found something else.” You’ll see before-and-after photos of your own ducts, and the written invoice matches the written estimate.
We also handle Air Duct Cleaning in Sansom Park and Dryer Vent Cleaning in Sansom Park for homeowners who want the full system addressed.

Call (361) 326-5060 for a free estimate; we’ll measure your leakage, show you the numbers, and give you a written price you can take to any other company for comparison.

We typically schedule duct sealing estimates within 2 – 3 business days for Sansom Park addresses, with actual sealing work booked within a week of estimate approval.

Yes, we seal ducts across the full city, including the older ranches near Lake Worth, the post-war homes along Jacksboro Highway, and the neighborhoods west of the railroad tracks where return-air systems face unique contamination challenges. Every Sansom Park ZIP code is in our standard service area.
We do not classify duct sealing as an emergency service; it’s a scheduled improvement that requires proper access, cure time for mastic, and pressure testing to verify results. However, our phones are answered by a live person 24/7, and we will expedite scheduling if you’re facing an urgent situation like a disconnected trunk line in extreme heat. Call (361) 326-5060 and we’ll find the earliest slot that allows us to do the job properly.
Pricing is consistent across our Dallas-Fort Worth service area, including Sansom Park. The variables that affect your quote are duct accessibility, system size, and leakage severity, not your specific city. A 1,200 square foot ranch in Sansom Park with crawl space access will typically fall in the same range as a comparable home in Fort Worth.
Every duct sealing job is covered by our 365-Day Done Right Promise in writing. If any sealed joint fails, airflow doesn’t improve as measured, or you find a missed connection within one year, Hollis returns and makes it right at no charge, including a free second visit. This is not a pro-rated or limited warranty; it’s a full year of coverage backed by a company that’s been in business since 2004.
