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.
Fast, Reliable Dryer Vent Cleaning Across Exton
Dryer vent cleaning in Exton typically runs $150 – $275 for a standard single-family home, and most jobs are completed in under two hours with the dryer back in service the same day. If you’re noticing longer dry cycles, a burning smell, or visible lint buildup around your exterior vent cap, your system is already working harder than it should.
We’ve been out to homes from the Whitford Hills subdivisions off Route 100 to the townhome clusters near the Exton Square Mall, and the pattern is consistent: Exton’s 1980s – 2000s housing stock was built with dryer vents that weren’t designed for today’s heavier laundry loads and longer cycles. Many of those original vent runs are 25 – 35 feet through finished basements or attic chases, with multiple elbows that trap lint in ways a simple shop vacuum can’t reach. Our crews dispatch from the Philadelphia office and carry Rotobrush rotary systems and Nikro negative-air equipment built for exactly these Exton configurations.

Dryer Vent Repair in Exton
Dryer Vent Repair in Exton becomes necessary when the vent line itself is damaged, disconnected, or improperly routed through finished spaces where it creates both a fire hazard and an efficiency problem. We see this most often in the split-level and colonial-style homes built during Exton’s 1990s expansion, where original flex-duct runs have sagged, torn at joints, or been crushed by storage items in basement ceiling chases. A typical Dryer Vent Repair in Exton runs $200 – $450 depending on access, materials, and whether rerouting is required.
Sagging and Disconnected Runs
Builder-grade flexible ducting in Exton homes was often supported with minimal strapping. Over years of heat cycling, it sags and creates low points where lint accumulates and moisture condenses. We replace these with rigid or semi-rigid aluminum runs properly supported to code, which eliminates the sag and improves airflow permanently.
Improper Terminations and Backdrafts
Some Exton homes have dryer vents terminating too close to HVAC intakes or under deck overhangs where moisture and lint redeposit on siding. We relocate terminations to proper clearances and install bird guards and backdraft dampers that keep pests and weather out while letting exhaust flow freely.
Dryer Vent Cleaning Company in Exton
Dryer Vent Cleaning Company in Exton describes exactly what Hollis provides: a scheduled, professional service that removes lint buildup from the full vent run, from the dryer transition duct through the exterior termination. In Exton’s climate, this isn’t optional maintenance. Humid summers cause lint to clump and stick to duct walls, while winter heating seasons mean the dryer runs longer with heavier loads, accelerating accumulation. A standard cleaning for Exton’s typical 3 – 4 bedroom home runs $150 – $275; homes with rooftop terminations or runs exceeding 35 feet may run $275 – $400.
Rotary Brush and Negative-Air Methods
Our crews use Rotobrush rotary brush systems that physically scrub lint from duct walls, paired with Nikro negative-air collection that captures debris at the source. For Exton’s longer vent runs through finished basements, this combined approach reaches what a homeowner’s leaf blower or vacuum attachment cannot.
Bird Guard and Cap Upgrades
Exton’s mature subdivisions have trees and shrubs that attract nesting birds. We install Guardsman and Abatement Technologies vent caps with integrated screens that stop birds and rodents without restricting airflow, a common failure point with hardware-store mesh inserts.
Trusted Brands We Service in Exton
We stock parts and accessories from Aprilaire, Abatement Technologies, and Guardsman for Exton customers, which means most repairs and upgrades don’t require a second trip. Our trucks carry replacement vent caps in standard 4-inch sizes, semi-rigid aluminum transition ducts, and bird guard assemblies that match the common configurations in Exton’s 1980s – 2000s housing stock. That inventory translates to faster turnaround and fewer return visits for homeowners in neighborhoods from Marchwood to Franklin Commons.
Common Dryer Vent Cleaning Problems We See in Exton Homes
- Long flex-duct runs through finished basements. Exton’s colonial and split-level homes often route dryer vents 25 – 40 feet through basement ceiling chases with multiple 90-degree elbows. Each elbow reduces airflow efficiency by roughly equivalent to 5 feet of straight duct, so a 30-foot run with three elbows performs like 45 feet. Lint accumulates at the elbows first, then backs up through the entire run.
- Original builder-grade plastic or foil flex duct. Many Exton homes still have the thin, corrugated flex duct installed during original construction. This material traps lint in its ridges, is easily crushed, and is no longer code-compliant for concealed installations. We replace it with smooth-wall aluminum that meets current standards.
- Rooftop terminations in townhome clusters. The townhome developments near Exton Square and along Route 100 often terminate dryer vents through the roof, which puts the cap out of sight and out of mind until airflow is severely restricted. These require specialized equipment and ladder work that most homeowners rightly avoid.
- Agricultural dust and pollen loading from former farmland. Exton subdivisions built over former farmland pull fine soil particulates and mold spores into laundry areas, where they combine with lint to form dense, adhered deposits. We see this repeatedly in neighborhoods off Route 100, where the ductwork carries a distinctive gray-brown loading that pure lint alone doesn’t produce.
