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 Marshfield, MA
Air duct cleaning in Marshfield, MA typically costs $450 – $850 for a whole-home system, with most jobs completed in a single visit. We’re Hollis Air Duct Cleaning, and we’ve learned that Marshfield homes demand a different approach than inland properties because of salt-air corrosion, crawl-space moisture, and aging galvanized ductwork common in this coastal town. Our crews carry Rotobrush rotary systems and Nikro negative-air machines to handle these conditions, and every job starts with a written price that doesn’t change. Call (361) 326-5060 for a free estimate.
Why Marshfield Homes Are Different
Marshfield sits on the South Shore with homes built on crawl spaces and varying elevations, many within a mile of salt water. That proximity changes what we find inside ducts. In summer, humid air carries salt inland, and when that moisture condenses in cool crawl-space duct runs, it leaves salt crystals on metal components. We’ve opened systems in Marshfield where galvanized steel had corroded through at the seams, something we rarely see in inland towns like Hanover or Pembroke.
The housing stock reinforces the pattern. Marshfield’s mid-century Capes and ranches often still run original flex duct or galvanized trunk lines, while newer construction near Brant Rock and Fieldston puts ducts in unconditioned attics and crawl spaces. Those spaces hit dew point in July and freeze in January, accelerating mold growth and duct fatigue. Humid summers and cold, damp winters create ideal conditions for mildew inside the system, especially when insulation has settled or vapor barriers failed.
We don’t guess at the condition. Our technicians inspect the full duct path, including crawl-space runs, and price the job before touching equipment. That’s The Garrison Standard, and it’s how we avoid the surprises that leave homeowners paying twice.
Our Main Marshfield Services
Marshfield homeowners call us most often for three jobs, each with its own page and pricing.
Air Duct Cleaning in Marshfield
Our Air Duct Cleaning in Marshfield service removes dust, mold spores, and salt residue from your entire forced-air system. We use Rotobrush rotary brushes on flex duct and Nikro negative-air machines on metal trunk lines, adapting the method to what your home actually has. In Marshfield, we often find heavy debris in return ducts pulling air from damp crawl spaces, and we address that directly rather than running a standard template.
Duct Sealing in Marshfield
Our Duct Sealing in Marshfield service closes leaks in supply and return runs using mastic sealant and metal-backed tape, not duct tape. In Marshfield, we seal more crawl-space connections than attic work because that’s where salt corrosion and rodent damage typically occur. Sealed ducts stop pulling musty crawl-space air into your living space and can cut heating and cooling costs by 15 – 25% in older homes with significant leakage.
