How Much Does Duct Repair & Sealing Cost in Columbus?
Duct repair and sealing in Columbus, OH typically costs between $300 and $1,200 for a standard single-family home, with most homeowners landing in the $400–$700 range depending on system size, the number of leaks, and access conditions. Minor sealing jobs on accessible runs can come in closer to $200–$300, while extensive repairs on older systems — common in Columbus neighborhoods like Clintonville, Hilliard, or Westerville where homes were built in the 1960s–1980s — can push toward $1,500 or more. Most jobs are completed in a single visit.
Duct Repair & Sealing Cost Breakdown (2026)
The table below reflects real pricing in the Columbus, OH market as of 2026. These are not national averages repackaged — they’re based on the type of work Summit Air Duct Cleaning Service Greater Columbus performs regularly across Franklin County and the surrounding area.
| Service Type | Typical Cost Range | Notes |
|---|---|---|
| Mastic sealant application (minor leaks, 1–2 zones) | $200–$375 | Accessible ducts, small homes or condos |
| Aeroseal duct sealing (whole-system) | $900–$1,500 | Best for hard-to-reach leaks; seals from the inside out |
| Manual duct repair (torn flex duct, separated joints) | $150–$400 per section | Price rises with attic or crawl space access |
| Full duct sealing (whole home, mastic + tape) | $500–$900 | Most common scope for 1,500–2,500 sq ft Columbus homes |
| Register/boot sealing | $75–$150 per register | Often bundled with a full sealing job |
| Duct cleaning + sealing combo | $550–$1,100 | Recommended before sealing to avoid trapping debris |
| Duct section replacement (severe damage) | $200–$600 per section | Necessary when flex duct is collapsed or rodent-damaged |
What moves the number up or down most in Columbus is access. Homes in older Bexley and German Village neighborhoods often have ductwork running through finished basements with limited clearance — that adds labor time. Homes in Dublin or New Albany with open attic runs are generally faster to work on. The material being sealed also matters: rigid sheet metal holds mastic well and requires less product, while deteriorating flex duct sometimes needs partial replacement rather than sealing alone. Columbus’s wide temperature swings between January lows and August highs also stress duct connections more than in more temperate markets, which is why we see a higher-than-average rate of joint separation in homes over 20 years old.
What Affects Duct Repair & Sealing Pricing in Columbus
- System size and number of zones: A 1,000 sq ft condo near Short North has far fewer linear feet of ductwork than a 3,200 sq ft two-story in Pickerington. More duct equals more product, more labor, and a higher total cost — typically $50–$150 more per additional zone.
- Access conditions (attic, crawl space, basement): Ductwork buried in a tight crawl space in Whitehall or running through an unfinished attic in Worthington requires more setup time and physical effort. Difficult-access jobs can add $100–$300 to the base price compared to open-basement installs.
- Type and condition of existing ductwork: Rigid metal ducts are more straightforward to seal and repair than aging flex duct that’s kinked, crushed, or partially collapsed. In homes built before 1985 — a common scenario in Columbus’s inner-ring suburbs — we frequently find duct materials that need replacement rather than patching.
- Extent of leakage: A duct system losing 15% of conditioned air needs more work than one with a single failed joint. If a blower door or duct pressurization test reveals widespread leakage, the scope expands accordingly. Many Columbus homeowners don’t know their leakage level until a diagnostic is done — which is why we offer free estimates before committing to a price.
- Sealing method chosen: Mastic and foil tape applied by hand is the standard approach and the most affordable. Aeroseal — a pressurized polymer mist injected into the duct system — costs more upfront but reaches joints that can’t be accessed manually and carries its own warranty from the manufacturer. For Columbus homes where a significant portion of ductwork runs through finished walls or inaccessible chases, Aeroseal often makes more economic sense over a 5–7 year horizon.
- Combination with duct cleaning: Sealing over dirty ducts traps debris and reduces the effectiveness of the sealant bond. If your ducts haven’t been cleaned in the last 3–5 years, bundling cleaning and sealing is the right call — and doing both in one visit saves on mobilization cost. Summit handles Duct Repair & Sealing in Columbus as part of a full-scope service, so you’re not coordinating two separate contractors.
How to Save on Duct Repair & Sealing
Getting the most value from a duct repair or sealing project in Columbus doesn’t mean finding the lowest bid — it means making sure you’re paying for work that actually solves the problem the first time. Here’s how to approach it practically.
Get a Diagnostic Before Agreeing to Full-System Sealing
Not every Columbus home needs a whole-system seal. A visual inspection and a basic duct pressurization test can pinpoint whether you have two leaky boots near the air handler or widespread joint failure throughout the system. Paying for targeted repairs on a 60% efficient system is money well spent; paying for full Aeroseal on a system that only needs two joints re-taped is not. Ask your contractor to show you the leak points before pricing the job.
Bundle Cleaning and Sealing in One Visit
When you schedule affordable duct cleaning and sealing together, you eliminate a second mobilization charge and ensure the sealant is applied to clean duct walls — which directly affects how well mastic adheres and how long the seal holds. In Columbus, bundling these two services typically saves $75–$150 compared to booking them separately, and the work takes roughly the same amount of time as two standalone visits would.
Don’t Wait Until HVAC Season Peaks
Columbus HVAC contractors — including duct specialists — get busy fast in May and again in September when residents are switching systems for the summer and fall. Scheduling in late winter (February–March) or early fall (October) typically means shorter wait times and occasionally better availability for same-week appointments. Pricing doesn’t fluctuate dramatically by season for duct sealing specifically, but availability does.
Understand What “Cheap” Duct Sealing Actually Costs You
A $99 “duct sealing special” often means a technician with a roll of HVAC tape who seals only the registers visible from the floor. That tape fails within 2–3 years in Columbus’s climate (the freeze-thaw cycle is hard on adhesives). Proper mastic or Aeroseal applied by a technician who actually locates the leaks — not just the ones that are easy to reach — holds for 10–20 years. The math is straightforward.

FAQs — Duct Repair & Sealing Cost in Columbus, OH
How much does duct sealing cost in Columbus, OH?
Duct sealing in Columbus typically costs $300–$900 for a standard home using mastic or foil-backed tape, and $900–$1,500 for whole-system Aeroseal. The right number depends on your home’s square footage, duct material, and how accessible the leaky sections are. Call (866) 531-6429 for a free, no-obligation estimate — we can usually give you a ballpark range before we even arrive.
Is it cheaper to repair or replace ductwork in Columbus?
Repair and sealing is almost always cheaper than replacement — often by a factor of three or more. Full duct replacement in a Columbus home runs $2,000–$6,000+ depending on system size and access, while targeted repair and sealing accomplishes the same functional result for $400–$900 in most cases. Replacement makes sense when ductwork is severely collapsed, rodent-damaged beyond repair, or original to a home built before 1970 with materials that no longer seal reliably. We’ll tell you honestly which category your system falls into.
How long does duct sealing last?
Properly applied mastic sealant lasts 10–20 years under normal conditions. Aeroseal, when applied to the manufacturer’s spec, carries a 10-year warranty on the sealant itself. In Columbus, where summer humidity and winter temperature drops stress duct connections, quality materials and proper application technique matter more than they would in a milder climate. HVAC tape alone — the kind you’ll find on a $99 “duct sealing” job — typically fails in 2–5 years.
Can duct sealing actually lower my energy bill in Columbus?
Yes — leaky ductwork in Columbus homes typically wastes 20–30% of conditioned air before it reaches the living space, according to Energy Star estimates. In a home spending $180–$220/month on heating and cooling (a reasonable Columbus average), fixing that leakage can translate to $35–$65/month in reduced utility costs. Payback periods on professional sealing jobs typically run 2–4 years, making it one of the higher-ROI HVAC improvements available to Columbus homeowners.
Do I need duct cleaning before duct sealing?
In most cases, yes — especially if your ducts haven’t been cleaned in the past 3–5 years. Sealing over dusty, debris-lined duct walls reduces sealant adhesion and can trap contaminants inside your system. At Summit Air Duct Cleaning, Michael Brown evaluates the interior condition of your ducts before recommending a sequence. If your ducts are reasonably clean, we can often seal the same day. If they need cleaning first, we handle both services in a single visit to save you time and money. Call (866) 531-6429 to talk through what your system needs.
Why Columbus Homeowners Choose Summit Air Duct Cleaning
Most duct sealing companies in Columbus send a technician you’ve never met, using equipment you can’t verify, on behalf of a company that may subcontract the work entirely. Summit Air Duct Cleaning works differently. Michael Brown — the owner — is the lead technician on your job. He’s the person who built this business’s reputation across nearly 800 customer reviews, and he’s the person accountable if something isn’t right.
Over eight years focusing exclusively on duct and HVAC cleaning work in Columbus, Michael has developed a clear read on what the local housing stock actually needs.

The full scope runs from cleaning to repair and sealing to air quality sanitizing, all handled by the same specialist rather than pieced together from multiple vendors.
