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 Oxon Hill-Glassmanor, MD
Dryer vent cleaning in Oxon Hill-Glassmanor addresses a specific problem shaped by this community’s 1960s and 1970s garden apartment complexes and ranch homes: long vent runs, shared walls, and summer humidity that turns lint into a dense, damp mat inside the pipe. We clean and photograph every vent we work on, and the written price you get before we start is the price you pay. Call (806) 606-6902 for a free estimate, which arrives in writing, not as a verbal range.
Why Oxon Hill-Glassmanor Homes Are Different
Oxon Hill-Glassmanor sits on the low Potomac River plain, where summer humidity hangs over the housing corridors along Indian Head Highway (MD-210) and St. Barnabas Road. That moisture does not stay outside. In 1960s and 1970s garden apartments, condensation forms inside supply ducts during long cooling seasons. Sheet metal gets damp. Lint, drywall dust, and construction debris from original build-outs absorb that moisture and hold it against duct surfaces. The result is a microbial environment that inland PG County communities like Bowie or Largo rarely see at the same intensity. Many homes here still run original sheet-metal ductwork or early fiberglass-lined ducts that are now brittle. Aggressive cleaning methods can crack those liners, so we adjust pressure, tooling, and inspection points for the older systems that dominate Oxon Hill-Glassmanor. In the apartment complexes off St. Barnabas Road, shared trunk lines often carry decades of deferred maintenance: original cardboard duct spacers, insulation fragments, and drywall dust packed into elbows. This is commercial-scale work inside residential buildings, and it demands equipment and documentation that a shop-vac service cannot provide.
Our Main Oxon Hill-Glassmanor Services
Homeowners in Oxon Hill-Glassmanor most often call us for two jobs: full air duct cleaning and HVAC cleaning. Both are documented with before-and-after photos, and both are priced in writing before work begins.
Air Duct Cleaning in Oxon Hill-Glassmanor
In Oxon Hill-Glassmanor, we clean supply and return runs, plenums, trunk lines, and registers using negative-pressure extraction connected to professional equipment from Rotobrush and Nikro. On older systems with fiberglass liners, we inspect first and reduce pressure where the liner shows cracking. Every job includes a Documented Photo Record of each duct run before and after. Air Duct Cleaning in Oxon Hill-Glassmanor has the full breakdown of scope, pricing, and what the photo record covers.
HVAC Cleaning in Oxon Hill-Glassmanor
HVAC cleaning here means blower wheel, evaporator coil, condensate pan, and plenum work, not just a duct blowout. In Oxon Hill-Glassmanor’s humid summers, coils grow biofilm fast, which cuts airflow and pushes damp air through the system. We clean with equipment from Abatement Technologies and document the coil and blower before and after. HVAC Cleaning in Oxon Hill-Glassmanor covers costs, process, and what we check on the HVAC side.

BeforeAfterDryer Vent Cleaning in Oxon Hill-Glassmanor
Dryer vent cleaning in Oxon Hill-Glassmanor deals with a problem that older housing stock makes worse: long vent runs though basements, crawl spaces, and shared walls in garden apartments, where lint accumulates faster than in newer construction. The local humidity turns that lint into a damp, compacted plug, which slows drying time and keeps the dryer’s high-limit thermostat from doing its job. We clean the full vent run from dryer transition to exterior termination, remove the lint, and photograph the inside of the pipe before and after so you can see what was actually in there. For the full service area details, see Dryer Vent Cleaning.
Dryer Vent Inspection
Signs you need it
Clothes take two cycles to dry, the dryer cabinet gets unusually hot, or the exterior vent flap barely opens while the machine runs.
What it costs in Oxon Hill-Glassmanor
A camera inspection runs $90-$150, and we apply that fee toward the cleaning if you proceed with the work on the same visit.
How we do it
We run a video scope from the dryer transition through the full run to the termination point, looking for blockages, crushed sections, disconnected joints, or bird nesting.
Lint Removal
Signs you need it
Visible lint accumulation around the dryer, reduced airflow at the exterior termination, or a burning smell during long loads.
What it costs in Oxon Hill-Glassmanor
Full lint removal from a standard single-family home vent run ranges $110-$180, depending on the length and number of elbows.
How we do it
We run a rotating brush down the full vent run from both ends where access allows, then capture loose debris with a professional vacuum system rather than pushing it back into the wall.
Vent Rerouting
Signs you need it
The current vent run exceeds code length limits, runs through an unconditioned crawlspace with a low point that collects water, or terminates under a deck or porch.
What it costs in Oxon Hill-Glassmanor
Rerouting a vent run in a typical Oxon Hill-Glassmanor home runs $180-$380, depending on the route and how many elbows the new run requires.
How we do it
We lay out the shortest compliant path, install rigid metal duct where the route allows, and seal the old and new penetrations against air and weather intrusion.
Bird Guard Installation
Signs you need it
Birds nest inside the exterior termination, or you find droppings, feathers, or nesting material around the vent hood.
What it costs in Oxon Hill-Glassmanor
A bird guard with proper termination hood runs $90-$180 installed, depending on the existing hood condition and whether mounting requires repair.
How we do it
We remove the existing hood, clean out any nesting material, install a screened termination hood that keeps birds and rodents out, and seal the opening.

|---|---|
| Dryer Vent Inspection | $90-$150 |

| Vent Rerouting or Bird Guard | $180-$380 |
How often should a dryer vent be cleaned in Oxon Hill-Glassmanor?
Every 12 to 18 months for a single-family home, and every 6 to 12 months for a garden apartment with a shared or long vent run. If the dryer takes two cycles, clean it now, then set a schedule. Call (806) 606-6902 and we’ll give you a written price before any work starts.
Do apartment complexes in Oxon Hill-Glassmanor need commercial vent cleaning?
Yes, the garden apartments off St. Barnabas Road and Indian Head Highway have shared dryer vent runs that most individual unit owners cannot access. We work on those multi-unit systems with commercial equipment and provide documentation for property managers and owners.
Duct Repair & Sealing in Oxon Hill-Glassmanor
Duct repair and sealing in Oxon Hill-Glassmanor means repairing original 1950s-1970s sheet-metal ductwork and early fiberglass-lined ducts that are now brittle and leaking at joints and seams. Every leak pulls humid outside air into the system, which raises humidity inside the home and drives mold growth inside the ducts themselves. We seal the leaks, repair or replace damaged sections, and photograph every repair before and after. For the full scope, see Duct Repair & Sealing.
Duct Sealing
Signs you need it
High utility bills, rooms that never reach the thermostat setpoint, or visible dust streaks around supply registers.
What it costs in Oxon Hill-Glassmanor
Aeroseal duct sealing in Oxon Hill-Glassmanor ranges $1,200-$2,500 depending on system size and measured leakage.
How we do it
We run a pressurization test to measure leakage, then inject sealant through the duct system and verify the post-seal leakage with a second test.
Flex Duct Repair
Signs you need it
Crushed or kinked flex runs in the attic or crawlspace, rooms with weak airflow, or visible condensation on flex duct insulation.
What it costs in Oxon Hill-Glassmanor
Flex duct section replacement runs $400-$800 for a standard 10-15 foot run, including materials and sealing.
How we do it
We remove the damaged flex section, replace it with properly supported R-6 or R-8 flex duct, and seal both ends with mastic and UL-181 tape.
Mastic Sealant
Signs you need it
Joints and seams that show visible gaps, dry tape, or stains where humid air has been leaking into or out of the ductwork.
What it costs in Oxon Hill-Glassmanor
Standalone mastic sealing of accessible joints runs $300-$500 for a typical single-family system of 10-15 linear feet of accessible trunk line.
How we do it
We clean the seam, apply mastic with a brush to fill and cover the joint, and leave the mastic to cure before re-pressurizing the system.
What Duct Repair & Sealing Costs in Oxon Hill-Glassmanor
| Item | Typical range in Oxon Hill-Glassmanor |
|---|---|
| Mastic sealing (standalone) | $300-$500 |
| Flex duct replacement | $400-$800 |
| Aeroseal whole-system sealing | $1,200-$2,500 |
How much does duct sealing cost in Oxon Hill-Glassmanor?
Standalone mastic sealing runs $300-$500, flex replacement $400-$800, and Aeroseal $1,200-$2,500. We write the price before work starts, and it includes the before-and-after photo record. Call (806) 606-6902 for an exact written quote.
Can leaking ducts make a home in Oxon Hill-Glassmanor more humid?
Yes, leaks pull humid outside air into the return side and push conditioned air out of the supply side. In Oxon Hill-Glassmanor’s low-lying Potomac plain, that adds measurable indoor humidity, which feeds mold inside the ducts themselves.
Air Quality & Sanitizing in Oxon Hill-Glassmanor
Air quality and sanitizing in Oxon Hill-Glassmanor addresses what the local climate leaves behind: sustained summer humidity that breeds microbial growth inside ducts, on coils, and in plenums even in homes with no visible water damage. The 1960s and 1970s garden apartments along St. Barnabas Road and Indian Head Highway often share return air paths, meaning a mold problem in one unit’s duct can carry into neighboring units. We treat the duct surfaces, document everything with photos, and provide a written scope so you know exactly what was treated and with what. For details on the methods, see Air Quality & Sanitizing.
Mold Treatment
Signs you need it
Musty odor from supply registers, visible discoloration inside ducts or on the coil, or allergy symptoms that worsen when the HVAC runs.
What it costs in Oxon Hill-Glassmanor
Duct system mold treatment runs $800-$2,000 depending on system size and the extent of visible growth.
How we do it
We clean the affected surfaces with negative-pressure extraction, then apply an EPA-registered antimicrobial and document the treated areas with photos.
UV Light Installation
Signs you need it
Recurring mold on the evaporator coil, persistent odor from the supply plenum, or a household member with a diagnosed respiratory condition.
What it costs in Oxon Hill-Glassmanor
A UV light system installed at the coil or plenum runs $950-$2,200 including the unit, installation, and wiring.
How we do it
We mount the UV lamp at the evaporator coil or supply plenum using manufacturer-specified brackets, wire it to the blower circuit, and confirm proper lamp positioning.
Air Purifier Install
Signs you need it
Dust accumulation on registers within days of cleaning, household odors that linger, or visible particles in the air when sunlight enters a room.
What it costs in Oxon Hill-Glassmanor
Whole-home air purifier installation runs $900-$2,500 depending on the system type and whether duct modifications are required.
How we do it
We install the purifier in the return or supply plenum per manufacturer specification, wire it to the air handler, and run a full airflow and installation check.
Odor Removal
Signs you need it
Persistent cooking, smoke, or pet odors that return within hours of cleaning or opening windows.
What it costs in Oxon Hill-Glassmanor
Odor removal with sanitizing and deodorizing treatment runs $500-$1,200 depending on the system size and the odor source.
How we do it
We clean the duct surfaces, apply a broad-spectrum deodorizer, and run the blower to circulate the treatment through the full duct system.
What Air Quality & Sanitizing Costs in Oxon Hill-Glassmanor
| Item | Typical range in Oxon Hill-Glassmanor |
|---|---|
| Odor removal / sanitizing | $500-$1,200 |
| Mold treatment | $800-$2,000 |
| UV light or purifier install | $900-$2,500 |
How long does duct sanitizing last in Oxon Hill-Glassmanor’s humidity?
UV light installations provide continuous treatment as long as the lamp is powered, and lamps are replaced every 12-24 months. Surface treatments last 6-12 months depending on humidity and system runtime. Call (806) 606-6902 for a written quote based on your system.
Does air duct sanitizing address mold in garden apartment shared return systems?
Yes, but shared return ducts may require building-wide coordination. We treat the accessible runs and document the treatment, but if the mold recurs from an untreated adjacent unit, the source has to be addressed at the building level.
