Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Mount Prospect, IL
Chimney repair in Mount Prospect usually means one thing: an original clay-tile flue from a 1950s ranch or split-level that has finally cracked after decades of Illinois freeze-thaw cycles. Homes built between 1945 and 1970 dominate the blocks off Northwest Highway and around Randhurst, and their single-flue exterior masonry chimneys were sized for furnaces long since replaced by higher-efficiency units. Duke Chimney Sweep repairs, relines, and restores those systems with specification-grade materials instead of guessing. Call (844) 660-6510 to schedule an inspection.
Why Mount Prospect Homes Are Different
The village grew fast along the Chicago & North Western’s Northwest Line after World War II, and the housing stock from that boom still defines most blocks. Brick ranches, frame Cape Cods, and split-levels went up quickly between roughly 1945 and 1970, nearly all with one exterior masonry chimney serving a fireplace, a furnace, or both. Those chimneys now sit 60 to 80 years old, and the clay tile liners inside them were never designed for modern high-efficiency appliances that vent cooler, wetter exhaust. Put a cooler flue gas against old terra cotta and the acidic condensate does slow, steady damage that most homeowners never see until an inspection camera does.
Mount Prospect’s winters accelerate every problem. Chicago-area temperatures swing through the freeze-thaw zone from 0°F to 32°F repeatedly between December and March. Water finds its way into hairline cracks in the crown or mortar joints, freezes, expands, and spalls the brick. By spring, chimneys on the exposed gable ends of older ranches near the Prospect Heights border often show crown deterioration, loose flashing, and flue tile fractures. We also find birds in uncapped flues during fall cleanings on those same wind-exposed chimneys, which is why we recommend checking caps before the first hard freeze.
Single-flue masonry chimneys on compact village lots also mean access matters. Many Mount Prospect chimneys sit close to property lines or under mature trees, so we bring equipment sized for tight roof access and stage work from the driveway rather than assuming wide-open space.

Our Main Mount Prospect Services
Most Mount Prospect homeowners reach us for one of two reasons: an annual chimney sweep before burning season, or a dryer vent that has not been opened in years. Both are part of the same venting system.
Chimney Sweep in Mount Prospect
Wood-burning fireplaces in older Mount Prospect homes build creosote fast, especially when burning unseasoned wood or running fires low and slow. Our sweep removes deposits from the flue walls, smoke shelf, damper, and firebox, then we camera-check the liner for cracks before the first fire of the season. On those gable-end chimneys exposed to winter wind, we almost always find cap and crown issues worth addressing during the same visit. For full details, see our dedicated page: Chimney Sweep in Mount Prospect.
Dryer Vent Cleaning in Mount Prospect
Over half the ranches and split-levels we service in Mount Prospect have dryer vents that have never been opened. Lint compacts over years, restricting airflow, extending dry times, and creating a fire risk that builds quietly behind the wall. We clean the full run from dryer to exterior termination, inspect the duct for disconnects, and verify the termination flap seals. It is a fire-safety service, not an add-on. See the full scope at Dryer Vent Cleaning in Mount Prospect.

Chimney Repair in Mount Prospect
Chimney repair in Mount Prospect is usually a liner question first. Original clay tile flues in postwar ranches and split-levels crack from decades of freeze-thaw stress and acidic exhaust from upgraded furnaces, and once a flue tile fails, the chimney is no longer safely venting smoke and carbon monoxide. The repair path depends on what the camera shows: resurfacing with HeatShield, a DuraFlex reline, or targeted masonry work at the crown and flashing. Duke Chimney Sweep stocks the professional-grade materials to restore before replacing, which keeps costs and disruption down on older Mount Prospect chimneys.

Chimney Crown Repair
Signs you need it
Spalling brick near the top of the chimney, visible cracks in the concrete crown, or water staining on ceiling drywall near the flue chase all point to a failing crown.
What it costs in Mount Prospect
Chimney crown repair in Mount Prospect typically runs $300 – $700 depending on access and the size of the crown.
How we do it
We remove loose crown material, apply a proper bond break, form and pour a new concrete crown with a drip edge, and finish it to shed water away from the flue and brick.
Chimney Liner Installation
Signs you need it
Cracked flue tiles visible on camera, chunks of terra cotta in the cleanout, or a furnace exhaust smell in the living space mean the liner has failed and the chimney is unsafe to use.
What it costs in Mount Prospect
Chimney liner installation in Mount Prospect typically starts around $1,700 and runs up, with HeatShield resurfacing often coming in lower than a full stainless reline.
How we do it
We spec the correct diameter from the appliance BTU rating, install a DuraFlex stainless liner or HeatShield resurfacer to code, and confirm draft and clearances before the system goes back into service.
Chimney Flashing Repair
Signs you need it
Water in the attic after rain, rusted or lifted flashing at the roofline, or streaking on the brick below the roof penetration all indicate failing flashing.
What it costs in Mount Prospect
Chimney flashing repair in Mount Prospect typically runs $400 – $800 for step flashing replacement on a standard ranch or split-level roof pitch.
How we do it
We remove the old flashing, inspect the roof deck underneath, install new step and counter flashing with proper overlap, and seal every seam so water cannot track back under the shingles.
What Chimney Repair Costs in Mount Prospect
| Item | Typical range in Mount Prospect |
|---|---|
| Chimney crown repair | $300 – $700 |
| Chimney flashing repair | $400 – $800 |
| Chimney liner installation (HeatShield or DuraFlex) | $1,700 and up depending on flue size and access |
What pushes cost up in Mount Prospect is access: chimneys on the gable end of a two-story split-level take longer to stage than a low ranch, and mature tree cover near the roofline sometimes requires extra lift equipment. We give a flat price after the camera inspection, so the quote covers the full job, not just the first hour.
How long does chimney repair take in Mount Prospect?
Most crown and flashing repairs finish in one day. A liner installation can take one to two days depending on flue height and whether HeatShield resurfacing or a full DuraFlex stainless reline is the right fix.
Do I need a new liner or can the old one be resurfaced?
HeatShield can restore many cracked clay tile liners without a full teardown, as long as the flue is structurally sound and properly sized. We only recommend a complete reline when resurfacing would leave clearance or draft problems, and you will see the camera footage either way.
Brands We Service in Mount Prospect
We spec and install Olympia Chimney and Famco components alongside Copperfield products and DuraFlex liner systems for Mount Prospect homes, keeping the same professional-tier parts on the truck that building contractors order, not hardware-store substitutes. Using our brands means repairs match the existing system and hold up through Chicago winters.
