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.

Dryer Vent Installation in Kensington
Dryer Vent Installation in Kensington becomes necessary when a home’s existing vent run is too long, too convoluted, or routed through a fire-risk zone like an unconditioned attic or crawl space. Many Kensington homes built between 1940 and 1980 were originally configured with vent runs that exceed modern safety lengths, or they terminate under decks where lint accumulates against wood framing. A proper installation re-routes the vent to the shortest, straightest path to exterior air, using rigid metal ducting rather than the flexible foil or plastic that older homes often have in place. In Kensington’s market, a full vent replacement with new termination cap typically runs $350 – $650, while a straightforward reroute of an existing run falls in the $250 – $450 range. We price this in writing before any cutting begins.
When Rerouting Makes Sense
Homes near the Town Center frequently have dryers positioned against interior walls, forcing vent runs through multiple bends before reaching daylight. Each 90-degree elbow reduces airflow efficiency by roughly equivalent to adding five feet of straight duct. Our crews map the path with a borescope, then propose the most direct route possible, often through a gable end or soffit that shortens the run by half.
Termination Cap Upgrades
The standard flapper caps installed in the 1970s and 80s stick open, invite birds, or clog with lint at the louvers. We install low-profile caps with backdraft dampers and removable screens that keep wildlife out while allowing full airflow. In Kensington’s oak-heavy canopy, this matters: squirrels and starlings nest in vent terminations year-round, and a blocked vent is a fire hazard within a single laundry cycle.
Dryer Vent Repair in Kensington
Dryer Vent Repair in Kensington addresses the gaps, separations, and corrosion that develop in vent runs after decades of use. The original galvanized steel ducting in post-WWII Kensington homes rusts from the inside out, especially in basement runs where summer humidity condenses on cool metal. A separated joint behind a finished wall can vent moist, lint-laden air into wall cavities for months before anyone notices the mildew smell. Repair work ranges from $125 for a simple reconnection and seal to $275 for replacing a corroded section with new rigid ducting. We inspect with a camera first, show you what we found, and write the price before we open a wall or ceiling.
Corrosion in Older Metal Ducting
Galvanized steel has a protective zinc coating that eventually wears thin. Once rust starts, it accelerates because lint holds moisture against the metal. Our crews cut out the damaged span and splice in new ducting with proper supports and sealed joints, not the foil tape that fails in three years. We also check whether the rust is localized or systemic, so you’re not repairing one hole while three more are forming downstream.
Joint Separation and Hidden Leaks
Mid-century renovations in Kensington often used friction-fit connections without mechanical fasteners or mastic sealant. Vibration from the dryer slowly works these joints apart. We find separations by measuring airflow at the exterior termination and comparing it to the dryer’s rated output. A significant drop means air is escaping somewhere in the run, and we trace it with a camera rather than guessing which wall to open.
Trusted Brands We Service in Kensington
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same tools commercial crews use in hospitals and schools. For filtration and vent protection products, we stock Guardsman bird guards and termination caps sized for the 4-inch rigid ducting common to Kensington’s housing stock. Because we keep these parts on the van, most repairs don’t require a return trip. If your vent system needs a component we don’t carry, we source it from regional suppliers with next-day turnaround rather than making you wait for a two-week special order. Every part we install is covered under the same 365-Day Done Right Promise as our labor.
Common Dryer Vent Cleaning Problems We See in Kensington Homes
- Excessive lint buildup from heavy canopy cover. Kensington’s mature oak and maple trees shed pollen, seeds, and leaf debris that gets pulled into laundry room vents through soffit gaps or open windows. This material mixes with dryer lint to form dense, fire-prone clogs near termination points.
- Long vent runs through unconditioned crawl spaces. The ranch and cape-style homes common along Kensington Avenue often route vents through damp, cool basements or crawl spaces where humidity condenses on lint, creating packed, moldy blockages that standard brushing won’t dislodge.
- Original foil or plastic flex hose still in service. Many 1960s and 70s Kensington installations used corrugated plastic or thin foil transition ducts that sag, kink, and trap lint. These materials are no longer code-compliant and represent a known fire risk that we replace with rigid metal on every job where we find them.
- Bird and squirrel nesting in unscreened terminations. The dense tree canopy around Kensington’s older neighborhoods provides constant wildlife pressure. We regularly remove nests of dried grass and twigs from vent caps, then install Guardsman screens that block animals without restricting airflow.
