Why Hollis Air Duct Cleaning Is Melrose’s Preferred Duct Sealing Company

We’ve been in business since 2004 as part of the Garrison Partners family, and our Duct Sealing in Melrose reputation is built on showing up when we said we would. Our Boston office dispatches crews who know that Melrose Highlands is not the same job as a north-side cape, and they plan truck and ladder placement before they leave because parking off Main Street and around the Common can eat twenty minutes if you don’t know the block.

Our customers in Melrose mention the same things in feedback: the technician called ahead, arrived uniformed, explained what he found with a camera, and the price matched the written estimate. No one likes a stranger in their basement; we make it predictable. Every repair carries our 365-Day Done Right Promise in writing. If the seal fails or the airflow drops again within a year, we come back and make it right at no charge, including a free second visit.

Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to book.

Air Duct Sealing in Melrose

Air Duct Sealing in Melrose is typically a diagnostic hunt through decades of modified ductwork rather than a simple tape-and-mastic job. A typical whole-system sealing project in Melrose runs $450 – $1,200, with smaller partial repairs starting around $280. The final cost depends on how much of the system we can access, whether we need camera inspection to locate hidden disconnections, and whether the job includes sealing around the air handler and return plenum.

Melrose’s housing stock drives this. Victorian and Colonial Revival homes from the 1880s – 1920s dominate neighborhoods near downtown and the Highlands, many converted to two-family units with ducts that were split, extended with flex, or crushed behind finished plaster walls. Mid-century capes and ranches on the city’s edges have shorter runs but often suffer from original joint seals that have dried and pulled apart after sixty-plus years of heating seasons.

What We Seal and Why It Matters

We seal supply and return joints, trunk connections, plenum seams, and register boots. In Melrose’s older homes, we also seal around the air handler cabinet because gravity-furnace conversions rarely include tight mechanical seals. Every gap we close returns conditioned air to the rooms that paid for it instead of leaking into your basement or wall cavities.

How We Find Leaks You Cannot See

Our crews use camera inspection and pressure testing to locate disconnected runs behind plaster or in unheated attics. We explain what we find before we cut access. In a two-family near the Melrose Highlands, our crew found a 1920s gravity-furnace conversion where the second-floor apartment had been trunked off the original system with a run that had been crushed behind a finished plaster wall. We confirmed it with camera inspection before opening anything. We rebuilt and sealed that run, then sealed the supply and return ducts at the air handler with mastic, because the old joints were leaking enough that the upstairs registers barely moved air. With the run reconnected and sealed, static pressure normalized and both units got even heat for the first time in years.

Duct Sealing Services in Melrose

Duct Sealing Services in Melrose require planning for equipment access, shared building systems, and the physical constraints of dense, hilly streets. A typical residential sealing job takes four to six hours; larger two-family systems or jobs requiring plaster access can run a full day. We price by the system, not by the vent, and we write that price down before work starts.

Our Duct Sealing team carries mastic, foil tape, mechanical fasteners, and replacement register boots on every truck. For jobs requiring access through finished walls or ceilings, we coordinate with you on placement and repair. We do not open plaster without explaining why and showing you the camera image that justifies it.

Scheduling Around Shared Systems

In Melrose’s converted two-families, one furnace often serves both units. We schedule sealing when both households can be present or when one owner has authority to grant access to common areas. We also inspect shared dryer vent stacks during these visits because a clogged lint pathway in a shared stack will keep a dryer cycling hot no matter how well the supply ducts are sealed, and we can schedule our Dryer Vent Cleaning in Melrose if needed.

Equipment Staging on Tight Streets

Our trucks carry Rotobrush rotary systems and Nikro negative-air machines, but on Melrose’s winding streets off Main Street and around the Common, we sometimes stage equipment from the nearest legal parking and run hoses rather than block traffic. We solve parking before we touch a register. This is standard operating procedure under The Garrison Standard, not an inconvenience we pass to you.

Trusted Brands We Service in Melrose

We seal and repair ductwork connected to equipment from every major manufacturer, and we stock sealing materials from Aprilaire, Abatement Technologies, and Guardsman for fast turnaround on Melrose jobs. Our mastic and foil tapes are rated for the temperature swings these ducts see, from zero-degree January intake air to attic spaces that hit 120 degrees in August. If your system includes a Honeywell or Aprilaire air cleaner or fresh-air intake, we inspect those seals as part of the job because Melrose’s mature oak canopy dumps leaves and pollen into outdoor intakes every fall. We don’t sell you parts you don’t need; we seal what you have and flag what we cannot fix with mastic alone.

Common Duct Sealing Problems We See in Melrose Homes

• Crushed or disconnected runs behind finished plaster. In older two-families near the Melrose Highlands and downtown, ducts split for upstairs apartments decades ago were often routed through walls with no access panel. The visible joints look fine; the real leak is hidden and kills airflow to entire rooms.
• Condensation and microbial growth in attic runs. Ducts routed through unheated attic spaces on Victorian homes collect humid summer air that condenses on cold metal. Sealing the joints without addressing the condensation traps musty growth inside the system.
• Dried joint seals on mid-century capes and ranches. Homes built in the 1950s and 1960s on Melrose’s north side often have original duct tape that has hardened and peeled. The leaks are obvious once we pressure-test, invisible until then.
• Shared dryer vent stacks blocked with lint. In downtown two-families where one furnace serves a split apartment system, sealing around the air handler won’t fix a shared dryer vent stack that’s clogged with lint. The lint pathway stays blocked and the dryer keeps cycling hot, wasting energy and creating a fire hazard.
