We’ve been working in ZIP code 02368 long enough to know what hides behind those finished basement walls. Randolph’s raised-ranch and split-level stock from the 1960s and 1970s carries ductwork that’s now 50–60 years old, often modified by multiple owners without professional oversight, making hidden damage and accumulated debris a routine finding on our jobs.

Why Randolph Homes Are Different

Randolph’s inland South Shore position subjects basement duct runs to humid maritime summers and harsh freeze-thaw winters, driving year-round HVAC use that accelerates dust and biological buildup. The town’s dominant 1960s–1970s raised ranches and split-levels contain original galvanized sheet-metal or early flexible duct routed through uninsulated basement cavities. Piecemeal basement-finishing projects — extremely common here — frequently left poorly sealed joints or unauthorized branch extensions. We’ve found supply and return plenums partially open to unconditioned space behind drywall, pulling basement air and pest debris into living spaces for decades before anyone noticed.

Air Duct Cleaning in Randolph

Our Air Duct Cleaning service in Randolph addresses housing stock that demands more than surface vacuuming. The original galvanized ductwork in these homes has accumulated 50–60 years of debris while suffering repeated freeze-thaw stress, and informal renovations have often compromised system integrity in ways a basic cleaning won’t reveal.

Residential Duct Cleaning

We dislodge built-up contaminants with Rotobrush mechanical agitation, extract them with Nikro HEPA negative-air machines, and verify results with before-and-after video. Standard residential duct cleaning for a single system with up to 12 vents runs $350–$550 in Randolph. Full system cleaning with video inspection typically falls between $550–$850. We clean it, repair it, and seal it — because a vacuum won’t fix an open plenum behind your finished basement wall.

Commercial Duct Cleaning

Commercial properties along Route 28 and near the Randolph Industrial Park face higher occupancy, longer runtimes, and stricter insurance requirements. We scale to the job with Abatement Technologies air scrubbers and systematic zone-by-zone cleaning. Commercial duct cleaning in Randolph ranges from $800–$2,500 depending on square footage and system complexity. Scott oversees the scope personally.

How much does air duct cleaning cost in Randolph?

Most Randolph homeowners pay $350–$550 for standard residential cleaning, or $550–$850 with video inspection and repair. Finished basements requiring drywall access, mold contamination, or pest debris add labor and HEPA containment time. We price upfront after inspection — not after starting work. Call (888) 597-5659 for an exact quote; estimates are free.

Dryer Vent Cleaning in Randolph

Dryer vent cleaning in Randolph typically costs $149–$289, with most jobs completed in a single visit. We’re regularly on High Street, North Main Street, and Turnpike Street addressing vents that run 25–35 feet through finished basements — configurations that trap lint and moisture far beyond what shorter runs experience. Our Dryer Vent Cleaning service starts with borescope inspection to see what’s hidden in walls and cavities.

Vent Cleaning & Lint Removal

We use Rotobrush brush-system technology paired with Nikro HEPA vacuum extraction to break packed lint loose at elbow joints and remove it completely. Standard vent cleaning for a straight run on a single-story home runs $149–$189; extended runs of 20+ feet with multiple elbows fall between $189–$249. A split-level on High Street we serviced had a 4-inch galvanized vent extended through a basement partition wall during a 1980s finishing project, adding three elbows that reduced airflow to dangerous levels.

Vent Rerouting

Rerouting removes hazardous flexible duct splices and runs new rigid or semi-rigid duct on proper slope with minimal elbows. Vent rerouting in Randolph typically costs $249–$389 and improves drying time by 40–50%. We commonly find piecemeal basement renovations left vents pinched, disconnected, or venting directly into the basement.

How often should dryer vents be cleaned in Randolph?

Most Randolph homes need professional cleaning every 12–18 months, though homes with long basement runs or heavy laundry usage benefit from annual service. Extended vent length and seasonal condensation in this climate accelerate lint accumulation beyond what shorter-run homes experience. Call (888) 597-5659 to schedule.

HVAC Cleaning in Randolph

HVAC cleaning in Randolph runs $280–$650 for full system service, with Scott handling every job personally. The town’s 50–60-year-old systems, humid summers, and freeze-thaw winters create unique contamination patterns in evaporator coils, blower wheels, and condensers that generalist cleaners miss. Our HVAC Cleaning targets these components with equipment matched to the problem.

Evaporator Coil & Blower Cleaning

The evaporator coil in Randolph’s raised-ranch air handlers collects moisture and microbial growth critical given humid summers and condensation-prone basement installations. Basic air handler and blower cleaning runs $280–$380; evaporator coil cleaning with antimicrobial treatment adds $180–$290. We’ve serviced blowers in split-levels where packed debris had reduced output by 40% of designed CFM.

Condenser Cleaning

Outdoor condenser coils in Randolph face salt and organic debris from maritime air that accelerates corrosion. Condenser coil cleaning runs $150–$220. Full system HVAC cleaning combining all components typically costs $480–$650. We remove the fan assembly, clean fins with foaming agent and low-pressure rinse, and verify refrigerant pressures.

My 1970s ranch smells musty from the vents — is the basement ductwork the cause?

Yes — musty odors from vents in 1970s Randolph ranches almost always trace to basement duct runs with moisture intrusion, unsealed plenum gaps, or disconnected flex duct pulling basement air. The original galvanized or early flexible ductwork was frequently modified during basement finishing without proper sealing. Call (888) 597-5659 and we’ll inspect for the specific failure; estimates are free.

Duct Repair & Sealing in Randolph

Duct repair and sealing in Randolph typically costs $280–$650 for most residential jobs, with same-week scheduling available. The town’s 1960s–1970s homes were built with galvanized sheet-metal sealed with cloth-backed tape or early mastic compounds that crumble after 50–60 years of coastal humidity and freeze-thaw cycling. Our Duct Repair & Sealing service replaces temporary fixes with permanent solutions.

Mastic Sealant Application

We remove degraded sealant entirely and apply fresh, fiber-reinforced mastic sealant to every joint and seam — a permanent fix tape alone can’t match. Full-system mastic sealant application in an accessible Randolph basement runs $280–$420. In uninsulated basements, this makes an immediate difference in airflow and air quality.

Metal Duct & Flex Repair

Original galvanized trunks corrode at seams where condensation pools during humid July and August weeks. Metal duct repair for sectional replacement of one trunk line costs $340–$580. Flex duct repair or replacement for a single run runs $180–$320, with properly supported, insulated flex installed to manufacturer spec. We’ve replaced entire 14-inch supply trunk sections near Highland Avenue and North Main Street.

We finished our basement in the 1990s and now have musty air — could ductwork be involved?

Yes — this is one of our most common Randolph calls. The 1990s basement finishing wave frequently buried supply trunks without proper caps or transitions, pulling humid basement air directly into your living-space duct loop. That musty smell isn’t “just basement” — it’s circulating through every room. We verify with camera inspection, seal openings, and sanitize. Call (888) 597-5659.

Air Quality & Sanitizing in Randolph

Air quality and sanitizing services in Randolph run $275–$650 depending on scope, with persistent musty odors, allergy flare-ups, and visible mold around vents signaling problems that basic cleaning won’t solve. The combination of 50–60-year-old galvanized ductwork, seasonal humidity, and decades of informal modifications creates conditions where contamination recurs unless treated at the source. Our Air Quality & Sanitizing service targets root causes.

Mold Treatment & Odor Removal

We treat active mold with EPA-registered solutions applied through our Rotobrush system, then address moisture sources like corroded joints or condensation on uninsulated ducts. Mold treatment in Randolph typically runs $350–$550 for a standard raised-ranch system. Odor removal with source identification costs $325–$500. On Highland Avenue, we traced a persistent musty smell to a return plenum left partially open behind drywall from a 1980s basement finishing project.

UV Light Installation

UV-C lamps positioned at the coil or supply plenum suppress mold and bacterial growth continuously. Installation typically costs $400–$650. Randolph’s humid summers and freeze-thaw winters create year-round condensation risk in basement duct runs, making UV a sensible preventive investment for many homes here.

Do you install UV lights for mold prevention in Randolph’s humid climate?

Yes — we install UV-C lamps sized for your specific system, positioned where they’ll suppress mold and bacterial growth continuously. Randolph’s humid summers and freeze-thaw winters create year-round condensation risk in basement duct runs. Installation typically costs $400–$650. Call (888) 597-5659 to discuss whether your system configuration makes UV appropriate.
