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 Marlborough, MA
Dryer vent cleaning in Marlborough costs between $89 and $189 for most homes, depending on vent length and access. Our crews work weekly in Marlborough, where early 20th-century worker housing and 1960s-80s ranches each bring their own ductwork problems. For a written price before any work starts, call (806) 606-6902.
Why Marlborough Homes Are Different
Marlborough’s housing stock splits sharply by era, and that split changes what we find inside ductwork. Homes near downtown and along East Main Street, many built before 1930, originally ran on steam or gravity hot-water heat. Their forced-air systems arrived later, often during the 1970s, with flex duct spliced onto old octopus-furnace sheet metal and stuffed into basement ceiling cavities that were never designed for access panels. Those runs collect debris at elbows and low points where no cleanout exists, so cleaning requires longer tooling and careful camera work rather than a quick pass.
The second tier, 1960s-80s ranches and split-levels along the Route 20 corridor, was built with forced air from day one. Their ducts are more accessible but no less dirty: Marlborough’s inland central-Massachusetts climate means furnaces run hard from November through April, sometimes six months straight. Dry winter air pulls in dust, muggy summers add condensation inside poorly sealed joints, and the result is a faster accumulation of particulate and mold spore than you’d see on the coast. Marlborough is a former mill city, and that history shapes the ductwork in ways that change both the method and the urgency of cleaning.
Our Main Marlborough Services
Two jobs dominate calls from Marlborough homeowners: full air duct cleaning and HVAC system cleaning. Both are documented with before-and-after photos of every duct run, priced in writing before the first panel comes off.
Air Duct Cleaning in Marlborough
In Marlborough’s older homes, duct cleaning often means working around retrofit systems with minimal access. We run a camera first to map what we’re dealing with, then use negative-pressure extraction with agitation tools sized for tight basement runs. You receive a written scope, a flat price, and a photo record of every run before and after. For the full breakdown, see Air Duct Cleaning in Marlborough.

HVAC Cleaning in Marlborough
Furnace and coil cleaning matters more in Marlborough because the heating season is long and blower motors inhale whatever sits in the return path. We clean the blower assembly, evaporator coil, and plenum, then document the results. A clean coil drops static pressure and shortens run times. For specifics on what this costs and how it works, see HVAC Cleaning in Marlborough.

AfterDryer Vent Cleaning in Marlborough

Dryer vent cleaning in Marlborough runs $89 to $189 for most single-family homes, with the higher end applying to long runs, second-floor laundry rooms, or vents that exit through the roof. Homes along the Route 20 corridor built in the 1960s and 70s often have longer vent paths than older downtown colonials, and that extra length means more lint surface area and more places for a clog to hide. Our crews use a camera to inspect every vent before and after, and you get a written price before we start. See our Dryer Vent Cleaning service page for the full breakdown across Massachusetts.
Dryer Vent Inspection
Signs you need it
Clothes take longer than 50 minutes to dry, the outside flap barely opens, or you can’t remember the last time anyone looked at the vent.
What it costs in Marlborough
A standalone inspection is $69 in Marlborough, and that price is credited toward cleaning if you proceed.
How we do it
We run a camera from the dryer connection to the exterior termination, photograph every section, and show you the images before recommending anything.
Lint Removal
Signs you need it
The dryer runs hot, the vent flap doesn’t move, or a musty smell persists even after clearing the lint trap.
What it costs in Marlborough
Lint removal inside a standard dryer vent cleaning runs $89 to $129; heavy blockages with packed lint at multiple elbows may run $149 to $189.
How we do it
We use a rotary brush with negative-pressure capture at the vent opening, pulling lint back toward the collection unit rather than pushing it outside.
Vent Rerouting
Signs you need it
The current vent path includes flexible foil hose, runs longer than 25 feet, or makes more than two 90-degree turns.
What it costs in Marlborough
Rerouting a dryer vent in Marlborough typically runs $180 to $350, depending on wall penetrations and whether rigid metal pipe replaces flex hose.
How we do it
We map the shortest legal path, replace flex with rigid smooth-wall pipe, seal every joint, and photograph the new run end-to-end.
Bird Guard Installation
Signs you need it
You hear birds or scratching near the vent exit, or nesting material keeps falling from the exterior hood.
What it costs in Marlborough
A bird guard installed on an existing vent termination runs $45 to $85 in Marlborough, including the part and labor.
How we do it
We clear any nesting, install a corrosion-resistant guard over the termination, and verify airflow with a manometer reading.
What Dryer Vent Cleaning Costs in Marlborough
| Item | Typical range in Marlborough |
|---|---|
| Dryer vent inspection | $69 |
| Standard lint removal | $89-$129 |
| Heavy blockage / long run | $149-$189 |
Why do longer dryer vents cost more in Marlborough?
Homes along Route 20 built in the 1960s and 70s often have vents longer than 25 feet, which requires additional time and tooling to clean. Extra length means more lint surface area, more elbows, and sometimes a roof exit that needs ladder work. Call (806) 606-6902 and we’ll explain the price for your specific vent length.
How do I know the vent was actually cleaned?
You receive a photo record of the vent interior before and after, from the dryer connection to the outside termination. That’s the same documentation standard we’ve held on every job since 2013, and it means you never have to take a technician’s word for it.
Duct Repair & Sealing in Marlborough

Duct repair and sealing in Marlborough is a different animal than in newer suburbs because so many downtown-side systems are improvised retrofit work: flex duct spliced to old sheet metal, joints taped badly, runs stuffed into chases with no room to work. Sealing those leaks properly means pulling panels, photographing every joint, and applying mastic or foil tape where the air actually escapes. In Marlborough’s five-to-six month heating season, a duct leak that dumps conditioned air into a basement cavity can add hundreds of dollars to a winter gas bill. See Duct Repair & Sealing for the complete service breakdown.
Duct Sealing
Signs you need it
Some rooms are noticeably colder than others, dust builds up fast near registers, or your utility bills climb every winter.
What it costs in Marlborough
Duct sealing in Marlborough runs $300 to $600 for a standard single-system home, depending on accessible joint count.
How we do it
We photograph every exposed joint, apply mastic sealant or UL-listed foil tape, then re-photograph each treated joint for the record.
Flex Duct Repair
Signs you need it
You see sagging or crushed flex duct in the basement, or airflow is weak at registers connected to flexible runs.
What it costs in Marlborough
Flex duct repair or replacement in Marlborough runs $150 to $400 per run, depending on length, diameter, and access.
How we do it
We replace crushed or kinked sections with properly sized flex, support every 4 feet, and photograph the new run before closing up.
What Duct Repair & Sealing Costs in Marlborough
| Item | Typical range in Marlborough |
|---|---|
| Duct sealing (per system) | $300-$600 |
| Flex duct repair (per run) | $150-$400 |
| Mastic sealant (per joint) | $15-$35 |
Why do retrofit duct systems leak more in Marlborough?
Pre-1930 colonials near downtown almost never had forced air originally. When ducts were added decades later, installers worked around old framing and steam pipes, leaving joints impossible to reach normally. Call (806) 606-6902 for a written assessment of your specific system.
Can sealing save enough to justify the fee?
A duct system leaking 20% of its airflow loses roughly one in five heated cubic feet to a basement or wall cavity. In a Marlborough winter with gas heat running five months straight, that adds up fast, and sealing pays for itself over two or three seasons.
Air Quality & Sanitizing in Marlborough

Air quality and sanitizing work in Marlborough addresses what grows inside ductwork during muggy summers and then circulates when the furnace kicks on. Poorly sealed ducts draw basement air, dust, and mold spores into the return path, especially in older retrofit systems that were never tight to begin with. We apply EPA-registered antimicrobial treatments and install UV or filtration equipment where the duct configuration allows. For full details, see Air Quality & Sanitizing.
Mold Treatment
Signs you need it
You see dark staining around register openings, smell mustiness only when the blower runs, or have had moisture issues in the basement.
What it costs in Marlborough
Mold treatment for ductwork in Marlborough runs $400 to $800 per system, depending on treated length and severity.
How we do it
We treat accessible interior duct surfaces with an EPA-registered antimicrobial, fog the plenum, and photograph affected areas before and after.
UV Light Installation
Signs you need it
Mold keeps returning after cleaning, or a household member has year-round respiratory symptoms that worsen when heat runs.
What it costs in Marlborough
UV light installation in Marlborough runs $500 to $900 for a single-lamp unit mounted in the supply plenum.
How we do it
We mount the lamp where it continuously treats air moving past the coil, wire it to run with the blower, and verify output with a radiometer.
What Air Quality & Sanitizing Costs in Marlborough
| Item | Typical range in Marlborough |
|---|---|
| Mold treatment (per system) | $400-$800 |
| UV light installation | $500-$900 |
| Odor removal | $200-$400 |
Does sanitizing replace duct cleaning in Marlborough?
No. Sanitizing treats biological growth, but it does not remove the debris that holds moisture and feeds regrowth. Cleaning first, then treating, is the sequence that holds up through Marlborough’s humid summers.
What’s the strongest evidence the treatment worked?
You receive before-and-after photos of treated surfaces along with a written record of the product used and where it was applied. If regrowth appears within 365 days, our Done Right Promise means we return and make it right.
