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.
Air Duct Cleaning in Randolph, MA
Dryer vent cleaning in Randolph is a different job than it is in most Boston suburbs, because so many of the town’s homes were built in the 1960s and 1970s with long, multi-elbow vent runs routed through finished basement ceilings. Add the humid coastal air that sits inside uninsulated duct runs all summer, and lint stops being a nuisance and starts being fuel. CleanRun brings a camera into every run, writes the price before work starts, and photographs everything before and after. Call (806) 606-6902 for a written quote.
Why Randolph Homes Are Different
Randolph’s housing stock clusters around the 1960s and 1970s raised ranch and split-level, with older post-war Capes mixed in through North Randolph and along the Route 28 corridor. The original sheet-metal ductwork in these homes is now 50-plus years old, and a large share of it was retrofitted when properties converted from oil-fired steam or hot-water heat to forced air. Those retrofit jobs often ran ducts through tight basement cavities and interior partition walls with minimal access points, which means most of them have never been professionally cleaned. Decades of dust, pet hair, drywall particles, and construction debris sit in those runs. The humid coastal plain south of Boston makes it worse: summer dewpoints regularly climb into the low-to-mid 60s, and any uninsulated or unsealed basement duct run is holding moisture against that old galvanized steel for weeks at a time. The result is a town where duct cleaning is less about cosmetics and more about correcting decades of accumulated material in systems that were never really accessible in the first place.
Our Main Randolph Services
Two services account for most of the calls CleanRun receives from Randolph homeowners, and each has its own dedicated page with full pricing and local detail.
Air Duct Cleaning in Randolph
Air duct cleaning in Randolph typically means working inside 50-year-old trunk lines and duct board that has never been opened. Our crews pressure-test access points, photograph the inside of every run, and extract debris with negative-pressure equipment from Rotobrush and Nikro. The full scoop on local pricing, signs, and what the camera finds is on the dedicated Randolph page: Air Duct Cleaning in Randolph.

HVAC Cleaning in Randolph
Randolph’s forced-air conversions left many homes with furnace and air handler cabinets full of debris that falls straight into the blower and coils. HVAC cleaning here means pulling the blower, cleaning the evaporator coil, and documenting the whole thing.

Before
AfterDryer Vent Cleaning in Randolph

Dryer vent cleaning in Randolph has to account for the way these houses were built: long vent runs that snake through finished basement ceilings, often exceeding 15 or 20 feet, with elbows added during retrofit work. Every bend catches lint, and the summer humidity in this coastal plain south of Boston turns that lint into a damp, compacted mass that restricts airflow and creates a genuine fire hazard. Our crews scope the vent with a camera before anything else, then run a rotating brush through the full length of the run and photograph the before and after. You get the photo record as part of the job, every time. For a complete overview of the service line, see Dryer Vent Cleaning.
Dryer Vent Inspection
Signs you need it
Clothes take longer than one cycle to dry, the dryer exterior gets unusually hot, or you notice a burning smell when it runs.
What it costs in Randolph
A camera inspection alone runs $95-$165 in Randolph, depending on access and run length.
How we do it
We run a video scope through the full vent from the dryer connection to the exterior termination and give you the still images from that pass.
Lint Removal
Signs you need it
Visible lint accumulates around the exterior vent flap, or the dryer stops mid-cycle on a high-limit error.
What it costs in Randolph
Full lint removal through the entire vent run costs $120-$180 in Randolph for most homes.
How we do it
We brush the entire vent run mechanically, vacuum the debris from both ends, and photograph the interior before and after.
Vent Rerouting
Signs you need it
The existing vent run exceeds 25 feet, passes through an inaccessible cavity, or terminates into a soffit instead of outside.
What it costs in Randolph
Rerouting a dryer vent in Randolph ranges from $250 to $500 depending on the new path and wall penetrations.
How we do it
We cut a new termination point, run rigid metal duct along the shortest practical path, and seal every joint with foil tape.
Bird Guard Installation
Signs you need it
Birds or rodents are nesting in the exterior vent hood, or you hear scratching at the termination point.
What it costs in Randolph
A bird guard with installation runs $75-$140 in Randolph depending on the termination type and height.
How we do it
We mount a galvanized or stainless steel guard over the exterior hood, secured to the structure and angled to shed rain.
What Dryer Vent Cleaning Costs in Randolph
| Item | Typical range in Randolph |
|---|---|
| Dryer vent camera inspection | $95-$165 |
| Full dryer vent cleaning (lint removal) | $120-$180 |
| Vent rerouting | $250-$500 |
| Bird guard installation | $75-$140 |
Why are some dryer vent cleaning quotes in Randolph so much cheaper?
A $49 or $79 coupon typically covers only the first few feet of vent. The moment a Randolph house has a 20-foot run through a finished basement ceiling, the price jumps. We write one flat price per vent run before work starts.
How do I know the dryer vent was actually cleaned?
We photograph the inside of the vent before and after every job, from the dryer connection to the exterior hood. You receive those images as part of the written job record.
Duct Repair & Sealing in Randolph

Duct repair and sealing in Randolph usually means finding leaks in 50-year-old galvanized trunk lines that were patched over by previous owners or never sealed properly during a forced-air conversion. The humid coastal air in this part of Norfolk County condenses inside unsealed basement runs, and every leak pulls that moisture along with dust into the conditioned space. We find the leaks with a pressure test, seal them with mastic or foil tape, and photograph every repair. For more on how the full service line works, see Duct Repair & Sealing.
Duct Sealing
Signs you need it
Rooms at the end of the run are consistently cold in winter, or your energy bill climbs year over year without a change in usage.
What it costs in Randolph
Sealing exposed ductwork in a typical Randolph basement runs $450-$700 for a full system.
How we do it
We brush-coat every accessible joint and seam with water-based mastic, then verify the seal with a pressure or smoke test.
Flex Duct Repair
Signs you need it
A flex run is crushed, kinked, or has pulled loose from its collar, leaving an upstairs room with almost no airflow.
What it costs in Randolph
Repairing or replacing a flex duct run in Randolph falls between $180 and $320 per run.
How we do it
We cut out the damaged section, fit a new insulated flex run over the existing collar, and cinch it with proper draw bands.
Duct Insulation
Signs you need it
Basement ductwork sweats in summer, leaving water stains on the floor or rust streaks on the metal.
What it costs in Randolph
Insulating an exposed trunk line and branch runs in Randolph runs $350-$650 depending on total linear footage.
How we do it
We wrap the duct with fiberglass insulation rated for the basement environment and secure it with foil-faced tape at every seam.
What Duct Repair & Sealing Costs in Randolph
| Item | Typical range in Randolph |
|---|---|
| Full system duct sealing | $450-$700 |
| Flex duct repair or replacement | $180-$320 per run |
| Duct insulation | $350-$650 |
Do I need a permit to repair ductwork in Randolph?
Most duct sealing and flex-run repairs do not require a Randolph permit because they are maintenance, not new installation. Any work that touches the furnace cabinet itself falls under mechanical code, and we pull the permit when it is required.
How much air is actually leaking from my ducts in Randolph?
Older retrofit systems in Randolph commonly leak 20 to 30 percent of conditioned air into basements and wall cavities. We test before and after sealing so you can see the measured change on the written report.
Air Quality & Sanitizing in Randolph

Air quality and sanitizing work in Randolph has to deal with what the local climate puts inside the ductwork: summer dewpoints in the mid-60s, basement runs that are not insulated, and 50-year-old galvanized steel that is often colonized by mold. The first step is never spraying something into the system; it is finding out exactly what is growing and where. We swab, photograph the interior, and then treat with an EPA-registered antimicrobial or install a UV system if the conditions call for it. For the full scope of this service, see Air Quality & Sanitizing.
Mold Treatment
Signs you need it
Visible mold patches inside the ductwork on the camera images, or a persistent musty odor that gets stronger when the blower runs.
What it costs in Randolph
Mold treatment for duct interiors runs $400-$800 in Randolph depending on the length of the affected run.
How we do it
We clean the affected surfaces mechanically first, then apply an EPA-registered antimicrobial and photograph the treated area.
Odor Removal
Signs you need it
Smells from past occupants, pets, or a prior water event return every time the system cycles on.
What it costs in Randolph
Whole-house duct odor removal in Randolph typically falls between $250 and $500.
How we do it
We clean the duct interiors, replace the filter media, and treat the return and supply runs with a thermal fog or vaporized neutralizing agent.
UV Light Installation
Signs you need it
Mold or bacteria keep returning on the evaporator coil after cleaning, or a household member has a documented respiratory condition.
What it costs in Randolph
A coil-mounted UV light installation in Randolph costs $600-$950 including the fixture and wiring.
How we do it
We mount the UV lamp above the evaporator coil, wire it to the blower circuit so it cycles with the fan, and verify the sensor output.
What Air Quality & Sanitizing Costs in Randolph
| Item | Typical range in Randolph |
|---|---|
| Mold treatment (duct interior) | $400-$800 |
| Whole-house odor removal | $250-$500 |
| Coil-mounted UV light installation | $600-$950 |
Will sanitizing my ducts actually fix the smell in my Randolph house?
If the odor source is inside the ductwork, mechanical cleaning followed by an approved antimicrobial or vaporized neutralizer removes it. We photograph the before and after so you can see what was actually there and what remains.
Is mold in ducts common in Randolph?
Yes, particularly in 1970s-era raised ranches with uninsulated basement trunk lines. Humidity inside the duct run in July and August creates exactly the conditions mold needs on older galvanized steel and fiberglass duct board.

Prices in Randolph push toward the upper end of these ranges when the ductwork is a 50-year-old retrofit running through finished basement ceilings, because access and run length drive labor. What does not change is the written price: Haven Standard Clause 1 means the number you approve before work starts is the number on the invoice when the crew leaves, every time.
