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 Foxborough
Foxborough’s mix of 1950s ranches near the center and newer builds around Gillette Stadium creates a ductwork landscape that changes block by block. We’re the Duct Sealing in Foxborough crew that knows the difference. Our technicians drive from the Boston office daily, so we’re typically on your driveway within the hour window we promised, not somewhere guessing which exit off Route 1 to take. Whether you’re in a cape off Central Street with original galvanized runs or a newer colonial near Patriot Place with flex duct that wasn’t sealed properly at the joints, we price it in writing before we touch anything. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Foxborough’s Preferred Duct Sealing Company
We’ve been sealing ducts in Norfolk County long enough to recognize the telltale signs of a north-side ranch with floor returns versus a Route 1 corridor home with basement trunk lines. That local pattern recognition matters because the sealing approach differs. Our Duct Sealing team carries mastic rated for the temperature swings Foxborough sees, from January nights below 10°F to July humidity that can loosen tape adhesive.
Foxborough homeowners leave feedback that mentions the same things: the technician showed up in the window, explained what he found with a camera, and the final price matched the written quote. No per-vent add-ons, no “we found another problem” surprises. Our 365-Day Done Right Promise covers every seal we apply. If it fails within a year, we return and fix it at no charge, including a free second visit. That’s written on every job, not implied.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. When you’re staring at a winter heating bill that’s $80 higher than last January and suspect leaky ducts, you want a human who can book the next available slot.
HVAC Duct Sealing in Foxborough
HVAC Duct Sealing in Foxborough addresses the conditioned air escaping through gaps, disconnected joints, and failed tape in your forced-air system. In this market, we see the problem most often in homes built between 1955 and 1975, where original ductwork was assembled with cloth-backed tape that dries out after decades of heating cycles. A typical whole-system seal in Foxborough runs $450 – $850 for an average ranch or cape, with larger colonials near Patriot Place running $750 – $1,200 if multiple trunk lines need attention. We also offer Air Duct Cleaning in Foxborough for homes where debris has accumulated at the leak points.
Leak Detection Before Sealing
We pressurize the duct system and use a calibrated fan to measure airflow loss. In Foxborough’s older homes with slab foundations and floor returns, we often find 15 – 25% leakage at the return plenum alone. The test takes 20 minutes and gives us a number we can show you.
Mastic vs. Tape Sealing
We apply water-based duct mastic with a brush or spray depending on access. In tight closets common to Foxborough capes, we use a flexible applicator. Mastic remains flexible through decades of thermal cycling, unlike foil tape that can peel when summer humidity hits 80%.
Duct Repair in Foxborough
Duct Repair in Foxborough becomes necessary when sealing alone won’t hold, typically because sections of galvanized steel have corroded through or flex duct has been crushed by storage in a basement or crawl space. We replace damaged sections with new ductwork, reconnect boots that have separated from floor registers, and rebuild return plenums that have collapsed. Repair jobs in Foxborough typically range from $280 for a single flex duct replacement to $650 – $900 for multiple section repairs in a ranch with extensive original metal duct. We also handle Dryer Vent Cleaning in Foxborough when lint buildup has damaged the vent run.
Corroded Metal Duct Replacement
Galvanized steel from the 1960s rusts from the inside out where condensation collects. In Foxborough homes near the Neponset River watershed, we see this more frequently because of higher ambient humidity. We cut out the damaged section and splice in new duct with mechanical fasteners, not tape alone.
Crushed Flex Duct Restoration
Homeowners in the older ranches near Cocasset Street often find flex duct flattened by boxes in a crawl space. We reroute where possible or replace with properly supported new flex, sized to the original airflow calculation.
Trusted Brands We Service in Foxborough
Our trucks stock sealing and filtration products from Aprilaire, Abatement Technologies, and Guardsman, plus rotary brush systems from Rotobrush for jobs where cleaning precedes sealing. For Foxborough homeowners, that means no waiting a week for a part to ship from a warehouse in Ohio. If your system uses an Aprilaire media air cleaner mounted on the return plenum we’re sealing, we can replace the filter during the same visit. We specify Guardsman-rated mastic for high-humidity applications, which matters in July when Foxborough’s wetlands push indoor relative humidity past 65%. The equipment roster is professional-grade, not hardware-store gear, and we explain what each tool does while it’s running in your home.
Common Duct Sealing Problems We See in Foxborough Homes
- Failed original tape at floor returns. In the ranch homes north of Central Street, cloth tape installed in 1962 has turned to dust. The return pulls attic or crawl space air directly into the system, bypassing the filter. We remove the residue and seal with mastic rated for the temperature range.
- Disconnected boots in slab-foundation homes. Around the capes near the center of town, the combination of concrete slab and floor registers means duct boots settle and separate from the subfloor. We reconnect and support them so the seal holds through heating season.
- Summer humidity degrading foil tape in basement trunks. Homes with full basements, more common east of Route 1, often have foil tape that loosens when July humidity peaks. We replace tape seals with mastic that won’t peel.
- Leakage at the air handler cabinet. In newer construction near Gillette Stadium, we find the factory seal on the air handler has gaps where the return connects. This is a 5-minute fix with proper gasket material, but it drops system efficiency by 8 – 12% if ignored.
Pricing for Duct Sealing in Foxborough, MA
A typical duct sealing job in Foxborough runs $450 – $850 for a ranch or cape with one system, measured by the number of accessible joints and the leakage rate we find during testing. Larger homes with two systems or extensive basement trunk work run $750 – $1,200. Duct repair, when sections need replacement, adds $280 – $650 depending on material and access difficulty. We do not price per vent. The figure we write down before work starts is the figure you pay. No dispatch fees, no “while we’re here” upsells. Factors that move the price: accessibility (crawl space vs. full basement), extent of corrosion damage, and whether we need to cut access panels in finished ceilings. Every estimate is free. Call (361) 326-5060 and we’ll schedule a technician to test your system and give you a written price.
