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.

AfterAir Duct Cleaning in Watertown, MA
Dryer vent cleaning in Watertown runs $129-$179 for a standard single-story run and is usually done within 90 minutes. Homes here, mostly built between 1900 and 1945 as steam-heated two- and three-families, were retrofitted for forced air decades later, and those retrofits put ductwork into chases, knee-walls, and basement cavities never designed for it. That’s why our crews treat every Watertown job as its own diagnostic exercise, not a routine walk-through. Call (806) 606-6902 for a written price before any work starts.
Why Watertown Homes Are Different
Watertown’s dominant housing type is the pre-WWII two-family or triple-decker, built for steam radiators, not air handlers. When forced-air systems came in during the 1970s through the 1990s, installers adapted to what existed: tight chases between studs, uninsulated attic knee-walls, and basement ceiling cavities that run parallel to old plumbing and steam lines. The result is ductwork with more joints, more bends, and more flex-duct splices than you’d find in a purpose-built suburban system, and that means debris accumulates faster at every change of direction.
The Charles River sits along Watertown’s southern and eastern edges, and low-lying streets near the river hold more ambient humidity than neighborhoods up the hill toward Belmont. Inside a poorly insulated basement duct run, that humidity raises condensation risk. In practice, we see more mold-favorable moisture conditions in Watertown basements than in towns set back from the river valley, which changes how we approach both cleaning and sanitizing.
Triple-deckers converted to condos present another wrinkle: stacked, per-unit duct systems installed by separate contractors in different decades. A sheet-metal trunk from an ’80s conversion gets spliced with flex duct added during a 2000s gut-rehab, and return-air pathways sometimes cross unit boundaries. That configuration complicates cleaning scope and billing, and it’s one reason we document every run with a photo record before and after.
Our Main Watertown Services
Most Watertown homeowners call us first about two things: the ductwork itself and the HVAC system attached to it. Both jobs in this city require reading the retrofit history of the house before touching a panel.
Air Duct Cleaning in Watertown
Air Duct Cleaning in Watertown means working through runs that were adapted to spaces never made for them, so our technicians map the system first, photograph every access point, and clean with negative-pressure extraction while the vents stay under controlled airflow. In triple-decker conversions, we note where return pathways cross unit boundaries and quote the scope in writing before starting. You get a documented photo record of every duct run when the crew finishes.
HVAC Cleaning in Watertown
HVAC Cleaning in Watertown covers the air handler, evaporator coil, blower assembly, and the plenum that connects to the duct runs. In Watertown’s retrofitted basements, the air handler often shares space with old steam piping, which leaves less clearance for access panels and makes removal of the blower housing more deliberate. Our written scope itemizes each component, and the before-and-after photo record includes the coil and blower wheel, not just the ducts.

BeforeAfterDryer Vent Cleaning in Watertown
Dryer vent cleaning in Watertown costs $129-$179 for a standard run and addresses the single most common cause of dryer fires in the United States. In Watertown’s pre-1945 homes, dryer vents were often added as afterthoughts during the same retrofit era that brought forced-air ductwork, which means long runs with tight bends, improvised terminations, and, occasionally, sections of flexible foil that collect lint by the spoonful. The river-humidity factor makes lint clumps stickier in basement-level runs. Our Dryer Vent Cleaning service includes a full photo record of the vent’s interior, before and after, so you can see what was removed. Call (806) 606-6902 for a written price.
Dryer Vent Inspection
Signs you need it
Your dryer takes longer than 40-45 minutes to dry a standard load, or the exterior vent flap doesn’t open fully when the dryer runs.
What it costs in Watertown
A camera inspection typically runs $79-$129 when booked as a standalone service, and we waive that fee when you proceed with cleaning on the same visit.
How we do it
We run a camera through the full vent length from the dryer connection to the exterior termination, photograph every segment, and give you the images with a written condition report.
Vent Cleaning
Signs you need it
The dryer runs hot to the touch, the laundry room feels humid while the dryer is on, or you see lint accumulating around the exterior vent opening.
What it costs in Watertown
Standard vent cleaning runs $129-$179 depending on the run’s length and number of turns, with written pricing agreed before we start.
How we do it
We push a rotating brush through the full diameter of the vent while a HEPA-filtered vacuum collects dislodged lint at the termination point, then photograph the interior again.
Lint Removal
Signs you need it
You can see lint packed against the interior walls of the vent when the dryer is disconnected, or the dryer has started tripping its high-limit thermostat.
What it costs in Watertown
Lint removal for a heavily obstructed run typically falls between $129 and $179, matching the standard vent cleaning range, with an additional access fee of $50-$75 if we need to cut a cleanout opening.
How we do it
We remove the dryer from the connection, brush out the entire run from both ends where accessible, and clear the exterior hood, then show you the before photo next to the after photo.
Vent Rerouting
Signs you need it
Your dryer vent runs more than 25 feet with multiple 90-degree bends, or it’s routed through a space where it cannot be cleaned from end to end.
What it costs in Watertown
Rerouting typically runs $220-$460 depending on the new path length and whether we’re working through finished walls, with a written quote before any cutting.
How we do it
We trace the existing route, diagram the replacement path with fewer turns and rigid duct where possible, and install the new run to current code with the exterior hood re-terminated.
Bird Guard Installation
Signs you need it
Birds are nesting in or near the exterior vent hood, or you hear scratching and chirping from the vent during spring and early summer.
What it costs in Watertown
A stainless steel bird guard, installed, runs $89-$129 when done as part of a cleaning visit.
How we do it
We clean the vent first, then mount a corrosion-resistant guard over the exterior termination with hardware that keeps it removable for future cleanings.
What Dryer Vent Cleaning Costs in Watertown
| Item | Typical range in Watertown |
|---|---|
| Camera inspection | $79-$129 |
| Standard vent cleaning | $129-$179 |
| Bird guard installation | $89-$129 |
How often should dryer vents be cleaned in Watertown?
Every 12 months for most households. Watertown’s aging vent runs and river-adjacent humidity make lint clump faster, so a yearly schedule is a sound baseline. Call (806) 606-6902 for a written quote.
Why does my dryer take two cycles to dry clothes in Watertown?
Usually a restricted vent. In Watertown homes, long retrofitted vent runs with multiple bends trap more lint, and the restricted airflow forces the dryer to work harder. Call (806) 606-6902 for a written quote.
Duct Repair & Sealing in Watertown
Duct repair and sealing in Watertown addresses the joints, seams, and connections that fail in retrofitted systems, and it’s where we find the largest share of energy waste. In this city’s pre-1945 housing stock, ductwork runs through unconditioned spaces with no insulation, so every gap means heated or cooled air escaping into a crawl space or knee-wall. Our Duct Repair & Sealing service starts with a camera inspection of every accessible run, and we quote the repair scope in writing before any work begins. Call (806) 606-6902.
Duct Sealing
Signs you need it
Rooms stay unevenly heated or cooled, the system runs more than expected, or your utility usage is higher than homes of similar size in your Watertown neighborhood.
What it costs in Watertown
Sealing accessible duct joints and seams typically runs $350-$700 depending on how many linear feet are involved and how many access points we need to open.
How we do it
We locate the leaks with a pressure test or visual inspection, then seal seams with mastic, a brush-on compound that hardens to a durable airtight barrier.
Flex Duct Repair
Signs you need it
Flexible duct sections are kinked, torn, disconnected, or sagging more than an inch per foot, which restricts airflow to specific rooms.
What it costs in Watertown
Flex duct repair or replacement typically runs $150-$400 per section depending on the length and whether new flex duct is needed.
How we do it
We replace damaged flex sections with properly sized duct, support it every four to five feet, and photograph each repair before and after.
Metal Duct Repair
Signs you need it
Sheet-metal trunks or branch lines show rust, crushed sections, disconnected joints, or holes from prior retrofit work.
What it costs in Watertown
Metal duct repair typically runs $200-$500 for a standard repair section, with full replacement quoted by linear foot after inspection.
How we do it
We cut out the damaged section, fabricate a matching gauge of metal, and seal the new connections with mastic, then add the photo record to your job file.
What Duct Repair & Sealing Costs in Watertown
| Item | Typical range in Watertown |
|---|---|
| Duct sealing | $350-$700 |
| Flex duct repair | $150-$400 per section |
| Metal duct repair | $200-$500 |
How do I know if my Watertown ducts are leaking?
Look for uneven room temperatures, dust streaks around registers, or higher-than-expected heating bills. A proper diagnosis includes a camera check of the runs. Call (806) 606-6902 for a written quote.
Is duct sealing worth doing before replacing a Watertown system?
Yes. Sealing leaks before replacing equipment means the new system actually delivers the airflow it was rated for, which changes the load calculation. Call (806) 606-6902 for a written quote.
Air Quality & Sanitizing in Watertown
Air quality and sanitizing in Watertown matters most in basements near the Charles River, where elevated humidity meets decades-old duct insulation and the organic debris that has accumulated inside it. In retrofitted pre-WWII homes, we find dust, skin cells, pet dander, and sometimes mold growth concentrated at the first elbow past the return grille. Our Air Quality & Sanitizing service pairs cleaning with treatment, so the problem is removed, not just masked. Call (806) 606-6902 for a written price before work starts.
Mold Treatment
Signs you need it
You see dark staining on the interior of ducts or on the air handler, or you smell a persistent musty odor that gets stronger when the system runs.
What it costs in Watertown
Mold treatment of accessible duct runs generally runs $400-$800, depending on the affected area’s size and how much duct needs to be accessed.
How we do it
We clean the affected surfaces first, then apply an EPA-registered antimicrobial rated for HVAC environments, and photograph the treated areas within the full before-and-after record.
Bacteria Sanitizing
Signs you need it
There’s been water damage, a sewage backup, or condensation pooling in the system at some point, and the air has a stale, unpleasant odor.
What it costs in Watertown
Bacteria sanitizing of the air handler and duct system typically runs $300-$600, with the exact price based on the system’s size and the number of access points.
How we do it
We fog the entire system with an EPA-registered biocide, following the dwell time and ventilation guidance on the manufacturer’s label, and document each step photographically.
Odor Removal
Signs you need it
A musty, smoky, or pet odor persists in the home even after cleaning, and the air blowing from the registers carries the same smell.
What it costs in Watertown
Odor removal typically runs $300-$500 depending on the system’s size and the source’s location, and it’s often combined with cleaning for a single written price.
How we do it
We run the blower while treating the plenum and supply runs with an odor-neutralizing agent, and we find the source first so the treatment targets the cause, not just the smell.
What Air Quality & Sanitizing Costs in Watertown
| Item | Typical range in Watertown |
|---|---|
| Mold treatment | $400-$800 |
| Bacteria sanitizing | $300-$600 |
| Odor removal | $300-$500 |
Is sanitizing worth it after a Watertown basement flood?
Yes, because flood moisture in a duct system creates conditions where bacteria and mold grow, and vacuuming alone won’t address the biological load. Call (806) 606-6902 for a written quote.
How do I know sanitizing actually worked in my Watertown home?
The photo record shows the treated surfaces before and after, and we can take surface samples if you want independent lab verification. Call (806) 606-6902 for a written quote.
