Rotobrush Duct Sealing Nationwide

Rotobrush Duct Sealing in Sandy Springs: What to Know First

We seal duct systems in Sandy Springs homes where Rotobrush equipment has been used, and most sealing jobs take one visit, usually three to five hours depending on access and how much of the ductwork needs attention. You get a written price before we touch anything, and that price doesn’t move once we’re in the attic or crawl space. If you own a Rotobrush system or had one installed and you’re noticing uneven room temperatures, dust on the registers, or a musty smell when the blower kicks on, call us at (229) 489-7780 and we’ll give you a straight read on what’s actually going on.

This page is for Sandy Springs homeowners who specifically want to know how Rotobrush products hold up, where they leak, and what it costs to make them right. Roy Castellanos and our crew have worked these systems in Sandy Springs for years, so we’ll explain what we see in the field, not what a brochure says.

How Rotobrush Products Fail – and How We Fix Them

The Rotobrush name covers a few different product lines, and each one has its own weak points when it comes to duct sealing. Here’s what we see in Sandy Springs homes, and how we address it:

• Rotobrush aiR+ systems with aging flex connections. The aiR+ is a duct cleaning machine, but homes where it’s been used often have older flex duct runs that were disturbed during cleaning. The inner liner separates from the outer jacket, and the connection at the plenum or register box loosens. We seal those transitions with mastic and mechanical fasteners, not tape, because Sandy Springs attics run hot in summer and tape adhesive gives out.
• Rotobrush portable units and the “post-cleaning leak” effect. The rotary brush knocks loose debris that may have been plugging small gaps in the ductwork. Once that debris is gone, the leaks are suddenly obvious. Owners think the cleaning created the problem. It didn’t; it revealed it. We find those separation points and seal them at the joint, which is where the leakage actually happens, not along the length of the duct.
• Register boots that were never sealed to the subfloor. In the older split-levels near Hammond Park, we routinely find return boots that were simply set into the floor opening with nothing sealing the gap between the metal and the wood. Air gets pulled from the crawl space or the wall cavity instead of the rooms. On a Rotobrush job, the brushing can knock those boots loose. We reset and seal every boot we touch, and we check the ones we didn’t touch too.
• Plenum leaks at the air handler. Sandy Springs heat pumps run long cooling cycles, and the temperature swings cause the sheet metal at the plenum to expand and contract. Over time, the factory tape fails. We see this on systems cleaned with Rotobrush equipment and every other brand. The fix is the same: remove the failed tape, clean the surface, apply mastic, and reinforce with metal screws where the duct meets the plenum.
• Supply trunk leaks in basements and crawl spaces. East Sandy Springs has a lot of homes with crawl spaces, and the duct trunks down there are often the original 30-year-old metal with failing seams. A Rotobrush cleaning won’t cause these leaks, but it’ll expose them once the airflow improves. We seal seams with mastic rated for the damp conditions you get in crawl spaces, not the cheap stuff that re-emulsifies.

Our Rotobrush Duct Sealing Process

Here’s how a typical Rotobrush duct sealing job goes when you call Hollis Air Duct Sandy Springs:

1. 1
   You call (229) 489-7780. A live person answers. We ask what you’re seeing: uneven rooms, dust, higher bills, a system that runs constantly. We schedule a time and tell you who’s coming, by name.
2. 2
   We walk the system. Roy or one of our techs goes into the attic or crawl space and physically inspects the duct runs, boots, and plenum connections. We’re looking for separated flex, failed tape, unsealed boots, and crossover leaks. We show you photos, even if you don’t want to crawl up there with us.
3. 3
   We give you a written price. You see exactly what we’ll seal, what materials we’ll use, and what it costs. That number doesn’t change when we’re on the job. If we find something unexpected, we stop and talk to you before doing anything beyond the scope.
4. 4
   We seal by the book. We use mastic and mechanical fasteners on joints and transitions. On access points that need to be opened for the work, we reseal those too. We don’t use duct tape. We don’t seal over mold or standing water; if we find those, we stop and tell you what’s needed before sealing anything.
5. 5
   We test by feel and by instruments. After sealing, we check airflow at the registers and look for any remaining leakage at connection points. We’re not going to hand you a made-up “sealed to spec” number; we’ll show you what we found and what changed.
6. 6
   We leave it clean and covered. The site looks the way we found it, or better. And every job is backed by the 365-Day Done Right Promise in writing. If a sealed joint fails within a year, we come back at no charge.

What Rotobrush Duct Sealing Costs in Sandy Springs

Here are honest dollar ranges for the Rotobrush duct sealing scenarios we see most in Sandy Springs:

• Single-boot reseal (one register or return that’s pulling air from the crawl space or wall cavity): $85 to $140 per boot, depending on access and whether the boot needs to be removed and reset.
• Full plenum reseal at the air handler (both supply and return sides): $325 to $575, depending on how much failed tape and mastic has to be stripped and whether the plenum needs reinforcement.
• Flex duct reconnection at three to five runs (where the inner liner has pulled off the collar): $280 to $520 for the set, including mastic, zip ties, and mechanical fasteners.
• Whole-system duct sealing for an average Sandy Springs home (2,000 to 3,000 square feet, includes boots, plenum, and accessible trunk seams): $850 to $1,800, based on access, linear feet of duct, and how much of it is in a crawl space versus an attic.

What moves the price: crawl space access, how many boots need to be pulled, whether existing duct insulation has to be repaired after we seal, and how much failed material has to be removed first. Some companies bid low and add “per-vent” charges once they’re in the house. We don’t. You see the whole number before we start.

Why Sandy Springs Homeowners Call Hollis Air Duct Sandy Springs for Rotobrush Work

As an independent Rotobrush service provider, we’re not tied to one manufacturer, which means we’ll tell you the truth about what your system actually needs. Clean ducts, straight answers. That’s the whole job.
