Rotobrush Duct Sealing & Repair Nationwide

Rotobrush Duct Sealing & Repair: The Houston Owner’s Guide

If your Rotobrush system has a failed sealing gasket, cracked collection hose, or a worn brush head that won’t hold suction, we stock the replacement parts and install them for a flat price, typically $145 to $390 depending on what failed. Most Rotobrush duct sealing and repair jobs in Houston are done the same day we arrive, and you’ll know the exact cost before we touch a thing. The way owners usually find out is gradual: suction drops, dust leaks around the hose connection, or the system starts sounding labored. Sometimes it’s sudden, like a split hose or a seal that finally gave out mid-job. Either way, you don’t have to live with a Rotobrush that’s working at half strength, and you don’t have to guess which part to order.

Which Rotobrush Models This Applies To

We work on Rotobrush models across the board: the aiR+ series, the older R500 and R700 units, and the compact BR series used in tighter Houston attics and crawl spaces. The key to matching the right part is reading the label on the motor housing, not the hose or the brush head. Rotobrush stamps the model and serial there, and that’s what tells us the correct gasket size, hose diameter, and brush-head mount. Here’s the gotcha we see often in Houston: the aiR+ uses an 8-inch hose connection, while the older R500 runs a 7-inch connection. Buy the wrong diameter and it’ll feel like it fits, but it’ll leak at the collar and burn through a filter in a week. OEM Rotobrush parts are well made, but for hoses, gaskets, and seals, quality aftermarket equivalents from suppliers we’ve vetted hold up just as well at a lower price. For brush heads and motor internals, we stick with OEM every time. The tolerances matter too much to gamble.

Signs Your Rotobrush Duct Sealing & Repair Is Failing

• Dust leaking around the hose connection. This usually means the rubber gasket has hardened or cracked. Houston’s heat accelerates rubber aging, and a gasket that lived a long life somewhere cooler will fail years earlier here. The fix is a new gasket and a properly seated collar.
• Noticeable suction loss at the brush head. Before you assume the motor is failing, check for pinholes or splits in the collection hose. Even a small tear drops suction dramatically, and a big one can pull attic insulation straight into the filter housing.
• The brush head wobbles or won’t spin true. Worn bearings or a bent mounting shaft cause this. Running it anyway chews through brush bristles and can score duct lining, which then needs sealing work you didn’t plan for.
• Strange smell from the unit while running. In Houston’s humidity, fine duct debris trapped against a hot motor can produce a musty, acrid smell. It’s often a clogged seal or a filter that’s bypassing because a gasket failed. Don’t ignore it; it means debris is getting where it shouldn’t.
• Rattling or vibration that wasn’t there before. Rotobrush systems are quiet when everything’s seated. A new rattle usually points to a loose clamp, a cracked hose cuff, or a brush head that’s no longer locking into the mount properly.

Replacement Cost & What’s Included

Here’s what Rotobrush duct sealing and repair costs in Houston, installed by us:

• Gasket or seal replacement: $45 to $90 installed, parts included.
• Collection hose replacement (7-inch or 8-inch): $120 to $220 installed, depending on length and whether you need a straight or tapered hose.
• Brush head replacement (OEM): $160 to $280 installed, depending on model and diameter.
• Hose cuff or clamp replacement: $35 to $70 installed.
• Full inspection plus all seals, gaskets, and hose assessment: $95, and if we find something during the inspection, that $95 is credited toward the repair.

The price we quote over the phone is the price on the invoice. No per-part surprise fees, no shop supplies line item. If the repair needs a part we don’t have on the truck, we order it and you don’t pay a second trip charge. Every repair gets our 365-Day Done Right Promise: if the part fails or the work wasn’t done right within a year, we come back and make it right at no charge to you.

DIY or Call Us?

Here’s the honest split. You can safely check three things yourself: read the model label on the motor housing so you know what you’re working with, run your hand along the hose (with the unit off) to find obvious splits or collapsed sections, and check whether the hose collar is seating fully into the connection point. Those three checks cost nothing and tell you a lot. What you should not do is open the motor housing or attempt to replace an internal seal without experience. Rotobrush units run tight tolerances, and an incorrectly seated internal gasket can cause motor overheating or debris bypass that you won’t see until it’s been running for an hour. We’d rather you call us at (940) 314-5008 and describe what you’re seeing. Paul Adeyemi will often be the one on the line, and he’ll tell you whether it’s worth a truck roll or whether a simple adjustment fixes it.
