AfterHow Much Does Duct Repair & Sealing Cost in Tampa?
Duct repair and sealing in Tampa typically costs between $450 and $1,850, with most homeowners in Hillsborough and Pinellas counties paying around $850 to $1,200 for a standard repair-and-seal job covering 10 to 15 linear feet of accessible ductwork. Full-system sealing using aerosolized methods runs higher, generally $1,500 to $2,500 for a 2,000-square-foot home. Your actual price depends on how much duct you have, how reachable it is, and whether you’re dealing with flex duct, sheet metal, or deteriorated duct board.
We’re Morton’s Air Duct Cleaning, part of the Cedarwell family of independently owned companies. We’ve worked in Tampa homes since 2005, and every job starts with a written price before any work begins. No surprises on the invoice, no “we found something else” phone calls mid-job. That’s the Cedarwell Care Promise, and we put it on every single visit.
Duct Repair & Sealing Cost Breakdown (2026)
Here’s what we currently see across Tampa neighborhoods, from Westchase to Brandon to South Tampa. These are real ranges we quote from, not national averages lifted from a generic cost calculator. Prices reflect 2026 material and labor rates in the Tampa Bay area.
| Service | Typical Cost Range in Tampa | Notes |
|---|---|---|
| Minor duct repair (small hole, loose connection, 1-2 joints resealed) | $175 – $400 | Most common issue we see in older Tampa ranch homes |
| Moderate repair and sealing (3-6 joints, section of torn flex duct replaced) | $400 – $900 | Typical for homes with ductwork in the attic |
| Full accessible duct sealing (all joints in attic or crawlspace, mastic + tape) | $900 – $1,800 | 10-15 linear feet; price climbs with duct count |
| Aerosolized whole-system sealing | $1,500 – $2,500 | For homes with significant leakage; confirms seal with before/after readings |
| Duct board section replacement (per 4-foot section) | $180 – $350 | Common in Tampa homes built in the 1970s-1980s with failing duct board |
| Flex duct replacement (per 25-foot run, insulated R-6 or R-8) | $300 – $550 | Includes new connectors, mastic, and support straps |
| Return air box repair or replacement | $250 – $650 | Depends on whether the plenum is corroded or just loose |
These numbers assume the ducts are accessible. In Tampa, “accessible” usually means an attic or a crawlspace with enough clearance to work. If your ductwork runs through finished ceilings, through a slab floor, or behind finished walls, the price changes because the access work changes. We’ll walk you through exactly where your ducts are and what that means for the quote before we touch anything.
Most Tampa homes we visit fall in that $850 to $1,200 middle range. That’s a house where the ducts are in the attic (which most are, given Tampa’s slab-on-grade construction), there are a few separated joints, maybe a torn section of flex duct by the plenum, and the homeowner is noticing uneven cooling or dust buildup around the registers.
Home values and neighborhood age matter less than you’d think. A $900 duct sealing job in Seminole Heights looks a lot like a $900 duct sealing job in Carrollwood. What moves the number is the duct material, the access, and how much total footage needs attention.
What Affects Duct Repair & Sealing Pricing in Tampa
Here’s what actually drives the number on your written estimate, based on what we see when we open attic hatches and crawlspace doors across Tampa Bay.
- Access to the ductwork. Tampa homes are overwhelmingly slab-on-grade, which means ducts run through the attic. A walkable attic with a permanent staircase keeps labor time down. A 130-degree attic in August, with scuttle access only, means our techs work in shorter shifts with more breaks, and the quote reflects that. It’s not a markup; it’s real time.
- Duct material and condition. Older Tampa homes, especially those built before 1990, often have duct board or thin-walled sheet metal that’s corroded from decades of humid attic air. Duct board soaks up moisture and crumbles when you try to reseal it. If the duct board itself is failing, you’re looking at replacement sections, not just sealing.
- Number of supply and return runs. A 1,200-square-foot bungalow in Riverside Heights might have eight runs. A 3,200-square-foot two-story in FishHawk Ranch could have twenty. Each run means joints, collars, and potential leaks. Duct count moves the price more than square footage does.
- Sealing method. Hand-sealing with mastic and UL-rated tape (what we do on most repair jobs) costs less than aerosolized sealing, but aerosolized sealing reaches leaks inside walls that hand methods can’t. If you’ve got a duct run in a finished chase between floors, aerosolized sealing is the only way to get at it without opening drywall.
- Humidity-driven damage. Tampa’s humidity is the great duct killer. Condensation on the outside of supply ducts in a hot attic soaks insulation wraps, rusts metal, and weakens connections. Homes without proper attic ventilation see this pattern more aggressively, and repairs often include refitting insulation around the duct, which adds material cost.
- Time of year. Between March and October, attic temps in Tampa routinely hit 120 degrees or more. Our crews schedule attic work earlier in the morning for safety, which means fewer attic-hours per day. That doesn’t change our hourly rate, but it does spread some jobs across two days, and the quote reflects the actual labor time.
One more local factor: building codes. Tampa sits in a wind-borne debris region, and code requires that flex duct in attics be supported no more than 5 feet apart and that all connections be mechanically fastened, not just taped. If a previous crew did a sloppy job with improper supports, the repair scope includes bringing those runs up to code. We do that as part of the repair, not as an upcharge with a scary name.
What Duct Repair & Sealing Actually Involves
Knowing the price is only useful if you know what the price buys. Here’s the step-by-step of what we do, in the order we do it, so you can follow along when you’re comparing estimates.
Step 1: We Find the Leaks
We don’t guess. We use a duct leakage tester, the same type of equipment used in Florida energy code compliance testing, to measure exactly how much air your ducts are losing. We’ll show you the number. In Tampa homes with original 1980s ductwork, it’s not unusual to see 25 to 35 percent leakage. A tight, properly sealed system should be under 10 percent.
Step 2: We Seal What Can Be Sealed
For accessible leaks, we apply UL-rated mastic at every joint, collar, and plenum connection, then follow with foil tape where the mastic needs mechanical support while it cures. Torn flex duct gets replaced, not patched. A patch on flex duct is temporary by definition, and we don’t sell temporary fixes. If the inner liner is torn, the section comes out and a new insulated section goes in.
Step 3: We Support and Secure
Flex duct that sags between supports creates its own leaks over time by pulling on joints. We re-strap everything to meet the 5-foot support code, using saddles or strapping that doesn’t compress the duct. Compressed flex duct loses R-value and breeds condensation, which in Tampa means mold on the outer liner within a season or two.
Step 4: We Test Again
After the repair, we run the leakage tester again. You’ll see the before and after numbers in writing. If the leakage isn’t reduced to a reasonable target, we keep working until it is. That’s not a promise we make loosely; it’s the whole point of hiring someone who owns the equipment and knows how to read it.
Step 5: We Leave the House Clean
Shoe covers go on at the door on every visit, no exceptions. Drop cloths go down anywhere we’re working inside the living space. Before we leave, we take a photograph of the clean-up and show it to you. That photo is part of the job record. If you have kids or pets, we work around nap schedules where we can, and we keep our tools quiet. The attic work is loud by nature, but we don’t run vacuums or blowers during the moments that matter to your family. That’s the Cedarwell C.A.R.E. values in practice: the house stays livable while we’re in it.
Our techs arrive in uniform and have passed background checks. Paul Adeyemi, who leads our Tampa team, has been with the Cedarwell family since the beginning. Paul trains every tech on the same protocol: explain what you’re doing before you do it, quote the price before you start, and leave proof that the job is done right.
Duct Repair & Sealing vs. Duct Replacement: How to Know Which One You Need
Most Tampa homes don’t need full duct replacement. They need sealing and targeted repair. But there are times when replacement is the honest recommendation, and we’ll say so even though it’s a bigger number.
Repair and sealing makes sense when: the ducts are less than 20 years old, the insulation is intact, the leakage is at the joints and connections rather than along the body of the duct, and there’s no visible mold or pest damage. The repair-and-seal route restores most of the efficiency loss at a fraction of replacement cost, typically $450 to $1,850 on most Tampa homes.
Replacement makes sense when: the duct board is crumbling to the touch, multiple sections of flex duct have failed inner liners, there’s rodent damage through the body of the ducts (Tampa attics see roof rats and squirrels, and they chew through flex duct like it’s bedding), or the system has already been patched so many times that the marginal cost of another repair approaches the cost of doing it right once. Full replacement in Tampa typically runs $3,500 to $8,000 depending on duct count and access, and we’ll only recommend it when the math supports it.
If you’re torn between repair and replacement, we’ll show you the leakage numbers and the condition photos. You decide with real information, not a sales script. Every recommendation is backed by our 365-Day Done Right Promise: if the repair doesn’t hold, we come back and make it right, and “done right” is stamped on every job we quote. No fine print gymnastics.
How to Save on Duct Repair & Sealing in Tampa
Saving money on duct work doesn’t mean finding the cheapest crew. It means not paying for work you don’t need and not ignoring small problems until they become big ones.
- Get the leakage test before you agree to anything. A company that quotes duct sealing without measuring leakage first is guessing. A guess can cost you more in the long run because you’ll pay for sealing that doesn’t solve your problem. We test first, always, and the test is part of the estimate process. Call (850) 738-9748 to schedule one; the estimate is free.
- Combine repair with a full cleaning if you’re already due. If your ducts need cleaning and you’ve got a few separated joints, doing both in one visit saves you a second service call. The cleaning equipment we run, from Rotobrush and Nikro, is designed to work alongside inspection and minor repair, so we’re not charging you for two separate trips to the attic.
- Address return-side leaks even if supply ducts look fine. Tampa homes lose as much air on the return side as the supply side, especially at the filter box and the plenum connections. Return-side sealing is often faster and less expensive, and it solves a lot of the dust and humidity complaints that get blamed on supply ducts.
- Check for obvious duct disconnects before you call. If you can safely look in your attic and see a flex duct that’s completely separated from its collar, that’s the problem. One reconnection might cost $175 to $300 depending on access, which is a lot less than full sealing. Don’t do the repair yourself, flailing around in a hot attic with a sharp duct knife and an aluminum tape roll is how injuries happen, but knowing what you’re looking at helps you have a smarter conversation with whoever you call.
- Ask about the warranty on the sealant and tape. Mastic improperly applied can crack within a season. We warranty our duct sealing work, and that warranty is covered by the 365-Day Done Right Promise, not a separate warranty registration you have to remember to fill out.
And the straightest path to saving money: get a written price before the work starts. Every Morton’s visit includes one. If another company won’t put a number in writing before they open your attic, walk away. You’d never buy a car without knowing the price, and duct work is no different.

FAQs – Duct Repair & Sealing Cost in Tampa
How much does duct repair cost in Tampa on average?
Most duct repair jobs in Tampa run $450 to $1,850, with the typical homeowner paying about $850 to $1,200 for moderate repair and sealing across 10 to 15 linear feet of accessible ductwork. A single reconnection or small hole patch can run as low as $175 to $400. The only way to know your number is to test leakage and inspect the ducts, which is exactly what we do before quoting. Call (850) 738-9748 for a free estimate with real numbers, not ranges pulled from a national database.
Is duct sealing worth the cost in Florida’s climate?
Yes, in Tampa’s humidity, sealing ducts typically pays back through lower cooling costs and less dust, and it often reduces the condensation that ruins insulation and duct board over time. Leaky ducts draw humid attic air into your supply system and push cooled air into the attic, which is a double loss. Homes we test in Tampa regularly show 25 to 35 percent leakage before sealing. Sealing brings that under 10 percent in most cases, which means the air you’re paying to cool stays in the rooms where your family actually lives.
How much does it cost to seal ductwork in a 2,000 square foot house in Tampa?
For a 2,000-square-foot Tampa home with accessible attic ductwork, full sealing typically costs $900 to $1,800 using mastic and tape at every accessible joint. Aerosolized whole-system sealing runs $1,500 to $2,500. The lower number assumes we can reach every connection from the attic; the higher number includes chasing leaks in enclosed chases and testing before and after to confirm the seal. We’ll give you a written price for your specific house before any work starts.
Is it cheaper to repair or replace ductwork in Tampa?
Repair and sealing is almost always cheaper, usually $450 to $1,850 for the typical Tampa home. Full duct replacement runs $3,500 to $8,000 depending on duct count and access. Replacement makes sense when the duct body itself has failed (crumbling duct board, rodent-chewed flex duct, inner liner tears), not when the connections are just loose. We’ll show you photos and leakage numbers so you can see which category your ducts fall into, and we won’t recommend replacement unless the repair math says it’s time.
Can you fix ductwork the same day in Tampa?
Yes, if the repair is accessible and the scope is small to moderate, our Tampa techs complete most duct repairs same-day. A single reconnection or a few joints of mastic sealing is typically a 2 to 4 hour job once the tech is on site. Larger jobs with extensive sealing or multiple replacement sections may take a second visit. Attic heat in the summer sometimes pushes work into two short shifts, but we’ll tell you the timeline before we start. Call (850) 738-9748 to check same-day availability.
How much does it cost to fix a disconnected duct in Tampa?
Reconnecting a single separated duct run in Tampa typically costs $175 to $400, depending on attic access and whether the collar needs to be re-secured or replaced. This assumes the duct itself isn’t torn and the separation is at the plenum or register boot. If the disconnection has been running for months in a humid attic, the insulation around it may be waterlogged and need replacement, which adds $50 to $150 to the job. We’ll show you the condition before we quote, so you don’t pay for hidden damage you can’t see.
