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 Braintree, MA
Dryer vent cleaning is the service Braintree homeowners call about most, and the reason is built into the housing stock. Thousands of split-levels and raised ranches constructed between 1950 and 1975 in neighborhoods like Braintree Highlands and South Braintree have laundry rooms placed dead center on the ground floor, which means the dryer vent often runs 15 to 30 feet horizontally before it exits the house. That’s well past the 6-foot maximum most dryer manufacturers specify, and in Braintree’s coastal humidity that long run collects lint fast. Oil-to-gas conversions left sticky soot inside ductwork all over this town, and the same pre-conversion era left dryer vent runs that were rarely cleaned at all. If you need dryer vent work, duct repair, or air quality service in Braintree, call (806) 606-6902.
Why Braintree Homes Are Different
Braintree’s postwar construction boom produced a dense stock of 1950s to 1970s split-levels, raised ranches, and Cape Cods across Braintree Highlands, South Braintree, and East Braintree. Most of these homes ran oil-fired forced-air heat for their first 20 to 40 years before converting to natural gas in the 1990s or 2000s. That conversion left behind a specific problem: galvanized trunk lines coated in a thick, sticky fuel-oil soot layer. Vacuuming alone won’t remove it, and when the new gas furnace heats those ducts, the residue can re-volatilize and push an odor through the house that homeowners can’t place. Pre-1978 construction also means many Braintree homes have asbestos-containing duct tape or duct board, which a technician has to identify before any cleaning starts. Add proximity to the Weymouth Back River estuary and Boston Harbor’s coastal air mass, and summer humidity pushes mold and biofilm growth inside aging ductwork faster than in more inland towns like Randolph or Milton. Heating season runs roughly October through April here, so forced-air systems cycle constantly, pulling particulates through duct systems that in many cases have never been professionally cleaned. Homes in Braintree with original trunk-and-branch ductwork often have long horizontal runs beneath subfloors and low-clearance plenum areas that are genuinely difficult to access without specialized equipment.
Our Main Braintree Services
Two services dominate the calls we take from Braintree homeowners: full air duct cleaning and deeper HVAC system cleaning. Both address the oil-soot residue and decades of accumulated particulate that define this town’s older duct runs.
Air Duct Cleaning in Braintree
Air duct cleaning in Braintree means dealing with what decades of heating conversions left behind. We photograph the inside of every duct run before we start and after we finish, so you see the oil-soot buildup on the galvanized trunk lines and the difference after extraction. In split-levels and raised ranches, the plenum and branch runs beneath subfloors are where the worst accumulation hides. Every job gets a written price before a single panel comes off. For the full scope of the work, read Air Duct Cleaning in Braintree.
HVAC Cleaning in Braintree
HVAC cleaning in Braintree goes beyond the ducts to the coil, blower, and drain pan, all of which take on the same oily residue the trunk lines do. A furnace converted from oil to gas will blow air across a coil that was never cleaned after the conversion, and that’s where re-volatilized odor starts. We pull the panels, photograph what’s there, and document what we remove. Read more at HVAC Cleaning in Braintree.

BeforeAfterDryer Vent Cleaning in Braintree
Dryer vent cleaning in Braintree is the highest-frequency service we run in this town, and it’s not close. The ground-floor laundry rooms common to 1950s-to-1970s split-levels and raised ranches in Braintree Highlands and South Braintree produce vent runs that stretch 15 to 30 feet horizontally before reaching an exterior wall. That’s three to five times the run length dryer manufacturers recommend, and coastal humidity makes the lint inside those runs denser and quicker to pack. A blocked vent forces the dryer to work harder, but the real danger is lint ignition: according to national fire data, the leading cause of dryer fires is failure to clean the vent. We’ve pulled 3-inch-deep lint mats out of Braintree vent runs that hadn’t been touched since the house was built. For full service details, see Dryer Vent Cleaning.
Dryer Vent Inspection
Signs you need it
Clothes take two or three cycles to dry, the dryer’s exterior gets unusually hot, or the flapper outside barely moves when the dryer runs.
What it costs in Braintree
Expect $85 to $150 for a camera inspection of the full vent run, including a written condition report.
How we do it
We run a camera through the entire vent from the dryer connection to the exterior cap, photograph the interior, and give you a written condition report with specific measurements.
Vent Cleaning
Signs you need it
The dryer runs hot, there’s a burning smell while it runs, or you can see lint pushing out the exterior vent cap.
What it costs in Braintree
Standard cleaning runs $135 to $220, with longer runs or roof terminations pushing toward the upper end.
How we do it
We use negative-pressure extraction to pull the lint out while brushing the full vent length, then photograph the interior before and after so you can see the difference.
Lint Removal
Signs you need it
Visible lint accumulation at the exterior vent, a dryer that shuts off mid-cycle due to overheating, or the vent hasn’t been cleaned in three or more years.
What it costs in Braintree
Heavy lint removal from a badly clogged run costs $150 to $260 in Braintree, depending on run length and how packed the line is.
How we do it
We break up the packed lint with a rotating brush, extract it with professional negative-pressure equipment, and photograph the now-clear run.
Vent Rerouting
Signs you need it
Your current vent run is much longer than manufacturer specs, makes sharp bends, or vents into an unconditioned attic or crawlspace.
What it costs in Braintree
Rerouting a vent to a shorter path runs $185 to $340, including the new exterior termination.
How we do it
We map the shortest acceptable route to an exterior wall, install new rigid duct, seal all joints, and terminate with a proper louvered cap.
Bird Guard Installation
Signs you need it
Birds are nesting in or near the exhaust cap, you hear scratching from the vent, or the existing cap is damaged and letting critters in.
What it costs in Braintree
A bird guard with installation runs $60 to $120, including the guard and fastening to the existing cap.
How we do it
We install a stainless-steel guard over the exterior termination, check that the flap still opens freely, and photograph the finished install.
What Dryer Vent Cleaning Costs in Braintree
| Item | Typical range in Braintree |
|---|---|
| Dryer vent inspection | $85 - $150 |
| Standard vent cleaning | $135 - $220 |
| Heavy lint removal | $150 - $260 |
| Vent rerouting | $185 - $340 |
How often should dryer vents be cleaned in Braintree?
Every 12 to 24 months for most Braintree homes, and every 12 months if your vent run exceeds 15 feet or your laundry room sits mid-house in a split-level. The long horizontal runs common here load faster than short straight runs.
Why does my dryer still take too long after cleaning the lint trap?
Because the trap only catches about 60% of the lint. The rest moves into the vent run. In Braintree’s older homes the vent often runs 15 to 30 feet, so the portion past the trap is where the blockage actually builds.
Duct Repair & Sealing in Braintree
Duct repair and sealing in Braintree is about stopping conditioned air from leaking into subfloor cavities, crawlspaces, and unheated split-level voids. The original trunk-and-branch systems in 1950s-to-1970s homes were built long before anyone sealed duct joints, and fifty years of summer humidity and winter heating cycles have loosened them further. Our job is to find the leaks, seal them, and document every repair. See Duct Repair & Sealing for the full scope of service.
Duct Sealing
Signs you need it
Rooms that never reach the thermostat temperature, rooms above the garage that are cold in winter, or utilities that run high without a change in comfort.
What it costs in Braintree
Aeroseal or brush-on mastic sealing for an average Braintree split-level runs $450 to $1,000, depending on the leak area.
How we do it
We measure leakage, seal accessible joints with mastic or inject sealant, then retest and photograph the sealed joints.
Flex Duct Repair
Signs you need it
Collapsed, kinked, or torn flexible duct visible in the attic or crawlspace, or airflow that’s fine at the trunk but weak at the register.
What it costs in Braintree
Replacing a damaged flex duct run costs $150 to $400 per run in Braintree, including new duct and connections.
How we do it
We remove the damaged flex, install new R-6 or better flex duct, seal both ends with mastic, and photograph the finished run.
Metal Duct Repair
Signs you need it
Visible rust-through or crushed sections of galvanized trunk line, often found in Braintree basements and crawlspaces.
What it costs in Braintree
Patching or replacing a section of metal duct runs $200 to $600 in Braintree, depending on access and the size of the section.
How we do it
We cut out the damaged section, fit new galvanized duct, seal the seams with mastic, and photograph the repair before the access is closed.
Duct Insulation
Signs you need it
Ductwork running through unconditioned space, condensation sweating on the outside of the ducts, or high summer cooling bills.
What it costs in Braintree
Insulating exposed ductwork runs $300 to $700 for a typical Braintree basement or crawlspace exposure.
How we do it
We wrap exposed ducts in fiberglass or elastomeric insulation, seal the seams, and photograph the completed insulation job.
Mastic Sealant
Signs you need it
Visible gaps at duct joints, cracked or missing tape from the original install, or dust streaks at register edges.
What it costs in Braintree
Mastic sealing of all accessible joints runs $350 to $700 in Braintree, depending on the number of accessible joints.
How we do it
We apply brush-on mastic to every accessible joint, let it cure, then photograph the sealed joints and run a leakage test.
What Duct Repair & Sealing Costs in Braintree
| Item | Typical range in Braintree |
|---|---|
| Duct sealing (mastic or Aeroseal) | $450 - $1,000 |
| Flex duct repair (per run) | $150 - $400 |
| Metal duct repair | $200 - $600 |
Do I need a permit for duct repair in Braintree?
Most duct sealing and flex duct replacement jobs don’t require a permit, but any work that changes the system’s air distribution or involves structural changes may. We confirm permit requirements before the job starts, not after.
How much air is leaking from my ducts in Braintree?
Studies show typical duct systems leak 20% to 30% of the air they move. In Braintree homes from the 1950s and 1960s with original unsealed trunk lines, we regularly measure leakage above 30% during initial testing.
Air Quality & Sanitizing in Braintree
Air quality and sanitizing work in Braintree is driven by two local factors: coastal humidity and oil-to-gas conversions. The Weymouth Back River estuary and Boston Harbor keep summer humidity elevated enough to grow mold and biofilm inside ductwork, and the oily residue from decades of oil heat gives that growth something to feed on. Sanitizing after a proper cleaning addresses what’s left. See Air Quality & Sanitizing for the complete service breakdown.
Mold Treatment
Signs you need it
Musty smell that strengthens when the heat or AC runs, visible mold on registers or inside the ductwork, or allergy symptoms that worsen indoors.
What it costs in Braintree
Mold treatment in the ducts runs $300 to $800 in Braintree, depending on the size of the system and the extent of treatment.
How we do it
We apply an EPA-registered antimicrobial to all accessible duct surfaces, then photograph the treated areas and provide a written record of the product used.
Bacteria Sanitizing
Signs you need it
Persistent odor that doesn’t respond to cleaning, a family member with recurring respiratory issues, or a known water intrusion event in the ductwork.
What it costs in Braintree
Whole-system bacteria sanitizing runs $250 to $600 in Braintree, depending on system size.
How we do it
We fog or spray an EPA-registered sanitizer through the full duct system with the blower running, then document the application and product.
Odor Removal
Signs you need it
A stale, oily, or combustion smell when the furnace runs, often reported after an oil-to-gas conversion in Braintree homes.
What it costs in Braintree
Odor removal with targeted cleaning and sanitizing runs $250 to $550 in Braintree.
How we do it
We clean the affected duct surfaces to remove the residue that’s re-volatilizing, then treat with an odor-neutralizing agent and photograph the before and after.
UV Light Installation
Signs you need it
Recurring mold growth in the coil area, persistent musty air despite cleaning, or a household with someone immunocompromised.
What it costs in Braintree
UV light installation runs $400 to $900 in Braintree, including the unit, wiring, and placement at the coil or main return.
How we do it
We mount the UV unit at the coil or in the main return, wire it to run continuously, verify the bulb output, and photograph the installation.
Air Purifier Install
Signs you need it
Household members with allergies or asthma, a home near busy Route 3 or I-93 corridors, or a desire for active filtration beyond a standard media filter.
What it costs in Braintree
Air purifier installation runs $500 to $1,200 in Braintree, depending on the purifier type and duct configuration.
How we do it
We install the purifier in the supply or return plenum, verify the electrical connection and airflow, and photograph the completed install.
What Air Quality & Sanitizing Costs in Braintree
| Item | Typical range in Braintree |
|---|---|
| Mold treatment | $300 - $800 |
| Bacteria sanitizing | $250 - $600 |
| UV light installation | $400 - $900 |
Will sanitizing my ducts actually remove the smell in my Braintree home?
If the odor is coming from duct surfaces, yes, but only after the residue that causes it is physically removed. In Braintree homes converted from oil to gas, that means cleaning the soot layer first, then sanitizing. Sanitizing alone won’t fix re-volatilized oil residue.
How long does air quality treatment last in Braintree’s climate?
Typical treatment lasts 1 to 2 years in Braintree, depending on humidity levels and how often the system runs. Homes near the Weymouth Back River estuary may see faster regrowth and benefit from a UV system installed at the coil.

FAQs About Air Duct Cleaning in Braintree
No. Dryer vent cleaning is classified as maintenance, not construction, and no permit is required for cleaning or inspection. If we recommend a reroute that changes the exterior termination, that work may require a mechanical permit, and we handle the permit check before any work starts.
Standard scheduling for Braintree appointments runs 2 to 4 business days. During peak fall heating season that can extend to a week. We don’t offer same-day, and we won’t pretend to; our scheduling is set in writing before the truck rolls, and the written price goes with it.
We serve both, but the property owner or their authorized property manager must approve the work and receive the written price before we begin. If you’re a renter in Braintree, coordinate with your landlord and we’ll handle the documentation they need.
