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.

HVAC Duct Sealing in Kendall West
HVAC Duct Sealing in Kendall West is almost always about stopping conditioned air from leaking into attics that stay hot and humid ten months a year. The job involves finding every gap, seam, and disconnected joint in your duct system – from the air handler plenum to each register boot – then sealing them with mastic and mesh (not foil tape, which peels in our humidity) so your blower’s output actually reaches the rooms you’re paying to cool.
A typical whole-system duct sealing in Kendall West runs $450 – $1,200 depending on system size, attic accessibility, and how many runs need attention. Partial sealing of one or two problem zones can run $180 – $450. We always inspect first with a camera, price it in writing, then do the work.
When Sealing Beats Cleaning
Many Kendall West homeowners call for Kendall West Dryer Vent Cleaning or duct cleaning when the real problem is leakage. If your rooms won’t hold temperature, your filter gets dirty in two weeks, or your energy bill spikes in July, the ducts may be dumping cooled air into the attic. Cleaning a leaky duct just removes the symptom; sealing fixes the cause.
Mastic and Mesh in Humid Attics
Foil tape fails fast in Kendall West’s year-round humidity. We use duct sealing mastic – a thick, flexible compound – reinforced with mesh fabric at joints and plenums. It stays bonded through wet seasons and dry seasons alike. This is standard practice for our Duct Sealing team on every job.
Duct Repair in Kendall West
Duct Repair in Kendall West usually means replacing or rebuilding sections of flex duct that have sagged, crushed, or grown microbial film from years of trapped humidity. The repair starts with a camera inspection to see what’s actually happening in your attic – disconnected collar, split inner liner, or a return run flattened behind the air handler platform. Then we pull the damaged section, rebuild with new flex or rigid pipe as needed, and seal every connection with mastic.
Single-run duct repair in Kendall West typically costs $280 – $650. More extensive rebuilds involving multiple runs or plenum work can reach $800 – $1,500. We price it before we start, and that price includes all materials and sealing.
Crushed Returns Behind the Platform
This is the most common duct repair we find in Kendall West’s 1990s two-stories. The return flex gets pinched behind the air handler platform during installation or settles there over years. The blower starves for air, pressure goes negative at every unsealed seam, and your attic sucks in dust while your bedrooms go stale. We rebuild the return path with proper support so it stays open.
Sagging Flex in Wet Attics
Flexible duct absorbs humidity, gets heavy, and sags between supports. Eventually it pulls apart at the collar or tears the inner liner. In Kendall West’s tropical monsoon climate, this happens faster than in drier parts of the country. We replace the compromised run and add proper strapping so it stays pitched for drainage.
Trusted Brands We Service in Kendall West
We carry parts and sealing materials from Rotobrush, Nikro, and Abatement Technologies on every truck, which means most Kendall West jobs don’t wait for a parts run. For filtration and air quality upgrades tied to your sealing project, we stock Honeywell, Aprilaire, and Guardsman products. Our technicians know which register boots and plenum adapters fit the builder-grade systems common to Kendall West’s 1980s – 2000s subdivisions, so we’re not guessing at connections or making return trips. That familiarity with your specific housing stock is part of why we’re able to price accurately before we start.
Common Duct Sealing Problems We See in Kendall West Homes
- Builder-grade flex sagging and pulling apart at collars. The same flexible duct used across Kendall West’s planned subdivisions absorbs attic humidity, gets heavy, and separates from its collar. Foil tape is the wrong fix – it peels in a season. We seal with mastic and mesh, which stays bonded.
- Crushed return runs behind air handler platforms. Standard to these floor plans, the return flex gets pinched where it bends behind the platform. The blower starves, static pressure drops, and air leaks out of every unsealed seam instead of circulating through your home.
- Microbial growth on duct exteriors from never-drying attic conditions. With indoor humidity often above 60% and AC running year-round, flex duct in Kendall West attics rarely dries out. Sealing over contaminated duct without cleaning first just traps the problem.
- Unsealed plenums and register boots on original 1990s installs. The connection between your air handler and the main trunk, and between each branch and its ceiling boot, was often left unsealed or taped poorly. These are predictable leak points we check first.
Pricing for Duct Sealing in Kendall West, FL
Whole-system duct sealing in Kendall West runs $450 – $1,200 for most single-family homes, with the typical three-bedroom, two-bath split-level falling near $650 – $850.

What moves the price: system size (more runs, more labor), attic accessibility (tight truss spaces take longer), and whether we find contamination that requires source removal before sealing. We inspect with a camera first, give you a written price, and that price does not move once work begins. No per-vent pricing, no add-ons at the door. Call (361) 326-5060 for a free estimate – we’ll quote your specific system after seeing it.

FAQs About Duct Sealing in Kendall West
Because the dominant problem in Kendall West’s 1980s – 2000s housing stock is leakage, not just dust accumulation. The tropical monsoon climate keeps flex duct moist year-round, causing sagging and collar separation that dumps conditioned air into the attic. Cleaning a leaky duct removes debris but leaves the energy waste and uneven cooling untouched. Sealing fixes the structural failure. Call (361) 326-5060 and we’ll inspect to tell you which problem you actually have.
We run a camera inspection through the duct and take static pressure readings at the air handler. A disconnected or crushed return shows negative pressure at the blower and visible separation on camera; a dirty but intact duct shows debris buildup with intact walls and normal pressure. In Kendall West’s uniform housing stock, we usually know the likely failure point before we climb into the attic. Call (361) 326-5060 to schedule an inspection.
Not always. Surface microbial growth on the exterior of flex duct from attic humidity can often be addressed by source removal cleaning, then sealing the duct and improving attic ventilation. If the inner liner is torn or the insulation is saturated, replacement is necessary. We inspect first and tell you which category you’re in before pricing either option. Call (361) 326-5060 for a camera inspection.
We access the attic through your hatch or gable vent, support ourselves on walk boards to protect your ceiling, and work systematically from the air handler plenum to each register boot. Every joint gets mastic and mesh. We run the system under negative pressure with HEPA filtration at our Nikro collector while we seal, so we’re not dumping attic dust into your living space. On tight lots with zero side yard, we don’t need exterior access – it’s all attic work. Call (361) 326-5060 for a written quote.
Yes, significantly. Leaky return ducts in Kendall West’s humid attics pull in dust, fiberglass, and microbial spores that bypass your filter entirely. Once returns are sealed and supported, your filter catches what it’s supposed to catch, and you’ll change it less often. Most homeowners notice less dust on surfaces within two weeks of a proper seal. Call (361) 326-5060 for an estimate – they’re free.
