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 Repair & Sealing Across Lombard
Duct repair and sealing in Lombard, IL typically runs $280-$650 for most residential jobs, with full-system sealing on older homes reaching $800-$1,400 when multiple runs need attention. We dispatch to Lombard from our Chicago office, and most repair calls are scheduled within two to three business days. Call (224) 344-8881 for a written estimate before any work starts.
We’ve been inside enough Lombard basements to know the pattern: raised-ranch off North Avenue, split-level near Westmore-Meyers Road, ranch bungalow south of Roosevelt Road - the ductwork tells the same story. Original 1950s-70s sheet metal, galvanized seams that have worked loose over sixty heating seasons, flex connectors crushed where someone stored holiday boxes against the plenum. Our Duct Repair & Sealing crews document every joint separation and rust scale with before-and-after photos, because in Lombard’s housing stock, the problem is usually structural, not just dirty.

Our Duct Repair & Sealing Services in Lombard
Duct Sealing
Most Lombard homes we enter lose 20-30% of conditioned air through leaks before it reaches the registers. On original sheet-metal systems in the Highlands or near Madison Meadow, we find joint separation at every trunk branch, seams that were never sealed beyond the factory fold, and return plenums drawing basement air through gaps you could slide a pencil into. Our sealing protocol starts with a static-pressure test to quantify the loss, then mechanical agitation to clear debris that would block adhesive contact, then mastic application at every joint and seam. We photograph each sealed joint; the photo record is part of your standard job deliverable. Typical duct sealing in Lombard runs $450-$850 for a full system.
Metal Duct Repair
Galvanized steel ductwork in Lombard’s postwar ranches doesn’t fail dramatically. It rust-scales from the inside, pits at low points where condensation collects, and separates at drive-cleat joints that were designed to hold together under positive pressure but weren’t built for sixty years of thermal cycling. We cut out damaged sections, fabricate replacement runs on site, and tie them back with S-cleats and mastic - not foil tape that peels when the basement humidity spikes in July. A single run replacement in Lombard typically costs $180-$340; multiple sections on a split-level near Northside Park can reach $600-$900.
Flex Duct Repair
Flex duct was the cheap fix of the 1980s and 90s, and we find it crimped behind air handlers, disconnected at plenum takeoffs, or crushed where storage habits changed after the original installation. The field vignette from our crew: on a raised-ranch off S. Main St near the village center, our tech pulled a supply trunk feeding the front bedrooms and found the original 1960s galvanized run separated at two joints with rust scaling and a crushed flex connector behind the air handler. After camera inspection, agitation tools and negative pressure, we mastic-sealed the joints, replaced the damaged flex section, and tied it back to the trunk; post-seal static pressure dropped and airflow at the far registers evened out. Flex repair in Lombard generally runs $220-$480 depending on access and length.
Duct Insulation
Uninsulated or degraded ductwork in Lombard basements and crawl spaces bleeds heat in January and gains humidity in July. We wrap repaired runs with formaldehyde-free fiberglass insulation, sealed at seams with mastic, to restore thermal efficiency. This matters especially in homes near Churchill Woods or along the Salt Creek watershed, where basement moisture runs higher than the village average. Insulation work is typically quoted as an add-on to sealing or repair, running $150-$350 for accessible trunk lines.

Our equipment roster includes Rotobrush mechanical agitation systems, Nikro HEPA-filtered negative-pressure extractors, and Guardsman mastic sealants - professional-grade tools customers can verify independently. For integrated air-quality systems, we work with Honeywell and Aprilaire components commonly found in Lombard HVAC setups, including whole-house humidifiers and media air cleaners mounted at the return plenum. We don’t sell equipment we can’t service, and we don’t service brands we can’t source parts for locally.
Common Duct Repair & Sealing Problems We See in Lombard Homes
- Original sheet-metal joint separation pulling in basement air. In Lombard’s 1950s-70s housing stock, drive-cleat and snap-lock joints have worked loose over decades of thermal expansion. Conditioned air escapes; unconditioned basement or crawl-space air gets drawn into returns. We find this in nearly every ranch between St. Charles Road and Roosevelt Road.
- Interior rust scaling on galvanized trunk lines. Sixty years of condensation cycles have left flaky oxidation inside metal ducts. The debris doesn’t brush out with a vacuum; it requires mechanical agitation to dislodge before sealing can adhere properly. Our Rotobrush systems are specified for this exact condition.
- Crushed or disconnected flex runs at the air handler. Storage habits change. A flex connector that was clear in 1987 now has a dehumidifier or storage bin compressing it against the plenum. The result: pressure swings, whistling, and rooms that never reach set temperature.
- Compacted pollen and organic debris in return trunks after Lilac Time window-opening. This one is Lombard-specific. The annual May festival draws residents to open windows just as lilac and tree pollen peaks. Technicians servicing homes within a few blocks of Lilacia Park consistently report a fine, compacted organic layer on duct interiors that correlates with years of spring window-opening during festival week - a seasonal pollen-loading pattern local crews recognize as a Lombard-specific challenge that doesn’t appear at the same intensity in comparable-age homes in neighboring Villa Park or Addison.

FAQs - Duct Repair & Sealing in Lombard
Weak airflow after cleaning usually means a disconnection or crush in the duct path, not debris. In Lombard’s older homes, we find flex connectors collapsed behind air handlers, trunk lines separated at joints, or supply runs pinched where basement storage habits have shifted over decades. A vacuum-only cleaning can’t fix a physical gap. We camera-inspect to locate the failure, then repair or replace the damaged section. Call (224) 344-8881 for a free estimate with written pricing.
Yes. Mastic outperforms foil tape on aging galvanized steel in Lombard’s humidity cycles. Foil tape adhesive degrades in basement moisture; mastic remains flexible and maintains its seal through thermal expansion. We apply mastic with a brush at every joint, seam, and penetration, then photograph the finished work. This is standard on all our metal duct repair and sealing jobs.
We run a camera through the duct run and take static-pressure readings before and after each section. A disconnected joint shows a pressure drop at the failure point and visible gap on camera. The photo goes into your documented job record. We don’t guess; we show you what we found before quoting the repair.
It should, if the temperature imbalance was caused by duct leakage. Sealing restores designed airflow to each register; static pressure readings before and after sealing quantify the improvement. On split-levels near Westmore-Meyers Road, we’ve measured 15-25% airflow increases at upstairs registers after trunk-line sealing. If the problem persists, we inspect for additional issues like insufficient return capacity or zoning problems.
Yes. We work with Honeywell and Aprilaire whole-house components mounted at the return plenum, including media air cleaners and humidifiers. If duct repair requires temporary disconnection of these units, we reinstall and verify function before leaving. Parts are sourced through standard distribution; no proprietary lockouts.
