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.

Why CleanRun Air Duct Cleaning Northbrook Is Palatine’s Preferred Duct Repair & Sealing Company
We’ve documented the inside of thousands of Palatine duct systems, and the pattern is unmistakable: this village’s housing stock - dominated by 1960s and 1970s ranch homes and split-levels - carries original forced-air ductwork now past the 50-year mark, much of it lined with fiberglass duct board that simply wasn’t designed to last this long. Our Duct Repair & Sealing team knows these homes block by block, from the pre-WWII bungalows near Slade Street to the sprawling ranches off Rand Road.
Palatine customers receive the same documented standard we apply everywhere: a written price before any panel comes off, background-checked uniformed technicians identified by name before arrival under Haven Standard Clause 3: Verified Crews, and a 365-Day Done Right Promise backed in writing on every job. We’ve served over 52,000 homes since 2013, every one with a photo record delivered as a standard job document - not an extra, not a favor.
Our dispatch from the Chicago office means we’re routing crews through Palatine regularly, not scrambling from some distant warehouse when a call comes in. We know the difference between a 1968 ranch on the east side and a 1979 split-level near Winston Park, and we know what the humidifier situation usually looks like before we park the van.
Our Duct Repair & Sealing Services in Palatine
Duct Sealing with Mastic Sealant
Palatine’s original duct systems were assembled with tape and hope, and five decades of thermal cycling have opened gaps at every joint and seam. We seal deteriorating trunk lines and air handler plenum connections with mastic sealant - a thick, fiber-reinforced compound that remains flexible after curing - applied over mechanical fasteners, not instead of them. In Palatine’s 1970s homes with fiberglass-lined supply trunks, we photograph liner condition before touching anything; once that liner is compromised by a previous tech’s aggressive brush, the damage is permanent and we document it to protect the homeowner and ourselves.
Air Leak Repair
Return duct leaks in Palatine basements pull in fiberglass insulation particles and concrete dust, pressurizing the system with material it was never meant to carry. We repair disconnected flex runs, patch corroded metal sections, and verify static pressure after sealing to ensure a whole-house bypass humidifier isn’t forcing conditioned moisture back into newly sealed joints. A sealed system with unverified pressure is a leak waiting to reopen.
Flex Duct Repair
Basement flex runs in Palatine’s split-levels sag, tear at hanger points, and detach from boots after decades of vibration. We replace deteriorated flex with properly supported new material, sealed to the trunk with mechanical fasteners and mastic, not duct tape. The camera shows the difference before we close up.
Metal Duct Repair
Original galvanized trunk lines in Palatine’s older homes corrode from the inside where humidifier moisture has pooled for years. We patch or replace damaged sections, re-seal joints, and insulate where condensation forms on cold surfaces. Every repair is photographed before and after.
Duct Insulation
Uninsulated or degraded insulation on Palatine’s basement and crawl-space duct runs creates condensation in summer and heat loss in winter. We install new insulation vapor-sealed at seams, particularly critical in homes where the humidifier has already saturated surrounding materials.

BeforeAfterTrusted Brands We Service in Palatine
Our equipment roster includes Rotobrush and Nikro for camera inspection and mechanical cleaning, plus Honeywell and Aprilaire components for humidifier pad replacement and control integration. We stock common Aprilaire bypass humidifier pads and Honeywell media locally because Palatine’s older furnaces use them almost universally, and a failed pad is often the moisture source behind the duct damage we’re called to fix. Customers can verify every brand independently - we name them precisely because we want you to look them up.
Common Duct Repair & Sealing Problems We See in Palatine Homes
- Saturated humidifier pads feeding moisture into fiberglass duct board. In Palatine’s 1960s and 1970s homes, an unmaintained Aprilaire or Honeywell bypass humidifier weeps directly into the trunk line, creating microbial growth that no fogging “sanitiser” upsell can actually reach or remediate. The pad must be replaced and the duct board must be sealed or replaced.
- Pre-existing liner damage from improper cleaning brushes. A previous technician used a stiff rotary brush on fiberglass-lined supply trunks, tearing or compressing the liner. We camera-inspect and photograph this damage before touching the system - otherwise the homeowner may reasonably believe we caused it.
- Reopened seams from unverified static pressure. A crew seals trunk joints beautifully but never checks return-duct and air handler static pressure afterward. The bypass humidifier continues pushing conditioned air against newly sealed joints until moisture re-wets the mastic and the leak returns.
- Disconnected or sagging basement flex runs. Original flex duct in Palatine split-levels has collapsed at hanger points or pulled from supply boots, dumping conditioned air into unfinished basement space and starving upstairs rooms. The homeowner feels “some rooms are always cold” without knowing where the air went.
Pricing for Duct Repair & Sealing in Palatine, IL

FAQs - Duct Repair & Sealing in Palatine
Because Palatine’s 1960s-70s forced-air systems run whole-house bypass humidifiers almost universally, we regularly find saturated humidifier pads feeding moisture straight into 50-year-old fiberglass duct board, creating microbial growth inside the trunk line that simply doesn’t occur in newer-construction suburbs with no such equipment. Once that duct board liner is torn or compressed - often by an aggressive brush from a prior cleaning - the liner cannot be restored, so we camera-inspect and photograph liner condition before anyone touches it. Call (224) 351-9772 for a written estimate.
Yes, but only with the right equipment and only after documenting pre-existing liner condition with a camera. We use Rotobrush systems with adjustable brush stiffness matched to the liner type, and we photograph every inch before contact. If the liner is already compromised, we show the homeowner the photo record and discuss repair or replacement options before proceeding. Call (224) 351-9772 to schedule an inspection.
No. A fogging treatment deposits chemical on accessible surfaces but does not penetrate saturated fiberglass duct board or remove the moisture source feeding the growth. In Palatine homes where a bypass humidifier has been weeping into the trunk line for years, the pad must be replaced, the duct board must be dried and sealed or replaced, and the humidity source must be controlled. Fogging is a surface treatment for a cavity problem. Call (224) 351-9772 for a real assessment.
Significant leaks show up in specific, observable ways: rooms that never reach temperature, dust streaking from supply registers, excessive furnace cycling, or utility bills out of line with similarly sized homes in your Palatine neighborhood. We measure static pressure and run a visual camera inspection to quantify leakage before recommending sealing - no guesswork, no pressure. The written estimate shows exactly what we’d seal and why. Call (224) 351-9772 to book.
After proper sealing, a MERV 11-13 pleated filter captures fine particulate without overloading the blower motor on Palatine’s older furnaces. Higher MERV ratings restrict airflow in systems not designed for them, and in homes with bypass humidifiers, that restriction can alter static pressure enough to cause the humidifier to behave unpredictably. We specify the right filter for your system as part of the job record. Call (224) 351-9772 for guidance on your specific equipment.
