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 Company in Bryn Mawr, PA
Air duct cleaning in Bryn Mawr typically runs $450 – $850 for a whole-home system, with most jobs scheduled within a week during peak fall and spring seasons. We clean ductwork in pre-1940 stone and stucco Main Line homes where gravity systems were retrofitted with forced air, leaving undersized runs and decades of accumulation behind plaster walls. Our crews dispatch from the Philadelphia office and carry rotary brush systems and negative-air machines built for these tight, legacy layouts. Call (361) 326-5060 for a free estimate.
Why Bryn Mawr Homes Are Different
Bryn Mawr’s housing stock shapes every job we do here. The town is dominated by large single-family homes built between the 1890s and 1930s, stone and brick construction with stucco facades, plus scattered post-war capes and ranches. Original ductwork is often unlined metal or transite, and piecemeal retrofits have left inconsistent runs with flexible duct crammed into attic conversions.
The humid Mid-Atlantic climate hits these systems hard. Summers bring high humidity that condenses in unconditioned attics and crawl spaces; winters drop temperatures that stress old seams. Fall and spring are our busiest seasons because pollen loads peak right when homeowners switch between heating and cooling.
Here’s what separates Bryn Mawr from neighboring Main Line towns: many basements and crawl spaces still contain original transite (asbestos-cement) ductwork. Pennsylvania DEP and EPA guidelines prohibit dry-sweeping these materials. Our technicians identify transite before touching it and handle it accordingly. This is not a standard truck-mount job. It requires someone who reads old duct layouts and knows when to stop.
Our Main Bryn Mawr Services
Most Bryn Mawr homeowners call us for one of three jobs. Each has its own page with full details on what to expect.
Air Duct Cleaning in Bryn Mawr
We clean supply and return ductwork with Rotobrush rotary brush systems and Nikro negative-air machines that pull loosened debris out rather than pushing it deeper. In Bryn Mawr, this means navigating tight plaster-wall chases, working around transite sections that must be bypassed, and accounting for gravity-system remnants that reduce airflow in retrofitted homes. Every job starts with a written price that does not move at the door. Air Duct Cleaning in Bryn Mawr
Dryer Vent Cleaning in Bryn Mawr
Dryer vent cleaning here often involves runs through thick masonry walls or long horizontal exits in older construction. We clear lint buildup with rotary tools and airflow meters to verify exhaust volume afterward. Blocked vents in these homes are a genuine fire hazard, especially where original vent routing was extended during renovations. We photograph the before and after so you see the difference.

Duct Sealing in Bryn Mawr
Duct sealing with mastic and mechanical fasteners closes leaks in metal and flexible duct where conditioned air escapes into attics or wall cavities. Bryn Mawr’s retrofitted systems are especially leak-prone at connection points between old and new sections. We pressure-test the system, seal accessible joints, and re-test so you see the improvement in delivered airflow. Duct Sealing in Bryn Mawr
