Why Hearthstone Chimney Co. of Chicago Is Mount Prospect’s Preferred Chimney Cleaning & Sweep Company
Mount Prospect homeowners call us because we understand what we’re looking at when we climb these roofs. The village’s housing stock is overwhelmingly concentrated in the 1950s-1970s post-war suburban build-out, meaning the neighborhoods are filled with ranch homes and split-levels whose original clay tile flue liners are now 50-70+ years old and systematically reaching end-of-life. The uniformity of this build era means chimney technicians here aren’t doing isolated one-off repairs. We’re working through entire neighborhoods of same-vintage chimneys with the same cracking tile and crumbling mortar, making liner inspection and relining the central service issue, not just annual sweeping.
Our reputation in Mount Prospect is built on documentation. Every Level 2 inspection ends with photos you can see and a plain-English verdict. The 90-Day Done Right Promise backs every job in writing with no arguing. Background-checked, uniformed technicians arrive when we say we’ll arrive, and most cleanings and inspections are finished in under two hours. We’ve served communities throughout the Chicago area since 2014, and we plan to be here in thirty more years. That changes how you treat a customer.
Our Chimney Cleaning & Sweep Services in Mount Prospect
Level 1 Inspection
A Level 1 inspection is the baseline for any Mount Prospect home that hasn’t changed its heating appliance or chimney configuration. We examine the readily accessible portions of the chimney exterior, interior, and connection, checking for creosote buildup, obstructions, and basic structural soundness. For the thousands of ranch homes near Central Road and Dempster Street built in the 1950s and 1960s, this annual check catches problems before freeze-thaw cycling turns a small mortar crack into a flue gas leak. A Level 1 inspection paired with standard sweeping runs $189-$279 in Mount Prospect.

Level 2 Inspection
Level 2 is what most Mount Prospect homes actually need. We use a specialized camera to inspect the full length of the flue liner, documenting every crack, offset joint, and spalled tile. This is non-negotiable when buying or selling a home, after a chimney fire, or when switching fuel types. Given Mount Prospect’s distinctive pattern of 1960s-70s split-levels with oversized combination flues left over from original oil or gas furnaces, the camera inspection often reveals what the eye cannot: a flue that was never resized after the furnace was swapped for a high-efficiency sidewall-vented unit. We were called to a 1963 split-level on Busse Avenue where exactly this scenario played out. The fireplace flue had an oversized combination flue left over from the original oil furnace. After the furnace was swapped to a sidewall-venting high-efficiency unit, the fireplace flue was never relined; we cleaned heavy creosote and installed a new DuraFlex liner to correct the chronic condensation and draft issues. Level 2 inspection with documentation runs $425-$675.

Creosote Removal
Creosote accumulates in every wood-burning chimney, but Mount Prospect’s legacy flue problems accelerate it. An oversized combination flue runs colder than a properly sized one. Cold flue walls condense more smoke particles into sticky, combustible creosote. We see this constantly in the split-levels near Golf Road and Wille Road, where homeowners burn seasoned oak and still face heavy Stage 2 or Stage 3 glazed creosote deposits. Our technicians use professional-grade rotary cleaning systems and, when necessary, chemical treatments to break down glazed deposits without damaging fragile 50-year-old clay tile. Creosote removal as a standalone service runs $249-$425, depending on severity and flue accessibility.

Soot Removal & Annual Sweep
For gas fireplaces and heating appliance flues, soot removal is the priority. Even clean-burning gas appliances produce acidic condensation that degrades mortar and metal components over decades. An annual sweep removes this residue and gives us the access to inspect for deterioration. In Mount Prospect’s climate, sitting about 20 miles northwest of Lake Michigan with frequent freeze-thaw cycling from November through March, that annual visit is preventive maintenance against water infiltration and liner failure. Our $89 Seasonal Tune-Up covers basic soot removal and inspection for standard gas setups.

Trusted Brands We Service in Mount Prospect
We don’t substitute builder-grade materials on Mount Prospect chimneys that have already survived half a century. For relining work, we specify DuraFlex stainless steel liners and HeatShield cerfractory resurfacing systems where the existing clay tile can be salvaged. For crown and flashing repairs, we source through Olympia Chimney and Famco to match original specifications. These are the brands that professional sweeps specify, and we stock common diameters and fittings so Mount Prospect customers aren’t waiting weeks for a special order. The right material for a 1960s ranch on Emerson Street is not the same as what works on a 1990s build, and we know the difference.
Common Chimney Cleaning & Sweep Problems We See in Mount Prospect Homes
- Oversized combination flues causing chronic creosote buildup. A very common find in 1960s-70s Mount Prospect homes is an oversized combination flue that once served both the original oil or gas furnace and the fireplace. After the furnace was swapped for a high-efficiency unit venting through a sidewall PVC pipe, the old shared flue was left serving only the fireplace but was never relined to the correct smaller diameter. The result is a chronically cold, oversized flue that accumulates heavy creosote and condensation moisture even with light use.
- Spalling clay tile from decades of freeze-thaw cycling. Mount Prospect sits about 20 miles northwest of Lake Michigan and experiences repeated temperature oscillation across the 32°F threshold from November through March. This freeze-thaw cycling is particularly destructive for aging mortar joints and clay tile liners, and it compounds on 50-70 year-old masonry faster than in drier inland climates.
- Crown and flashing failures from exterior water intrusion. Original brick-and-mortar crowns and flashing fail prematurely under this same cycling stress, allowing water entry that accelerates interior masonry decay. We find this on nearly every inspection call in the older neighborhoods near Main Street and Northwest Highway.
- Offset joints and cracked tile creating flue gas leakage paths. In split-levels with multiple heating zones, the thermal expansion differential between floors stresses flue joints over decades. What starts as a hairline offset becomes a pathway for carbon monoxide and combustion gases into wall cavities. Camera inspection finds what visual inspection misses.

FAQs - Chimney Cleaning & Sweep in Mount Prospect
Your flue is probably oversized for the fireplace alone. In Mount Prospect’s 1960s-70s split-levels, many chimneys were built as combination flues serving both the original furnace and the fireplace. When the furnace was replaced with a sidewall-vented high-efficiency unit and the flue was never resized, the remaining fireplace flue is too large in diameter. It runs cold, causing smoke to condense into creosote on the walls. Burning seasoned wood helps, but it cannot overcome a fundamentally wrong flue diameter. We correct this with a properly sized DuraFlex liner after thorough cleaning. Call (888) 289-6055 for a camera inspection.
Yes. The clay tile liner is now 70 years old, and in Mount Prospect’s climate, freeze-thaw cycling has been attacking the mortar joints for decades. Exterior brick can look sound while interior liner tiles have spalled, cracked, or developed offset joints that leak flue gases. Only a camera inspection reveals the true condition. We find dangerous liner failure in Mount Prospect chimneys with pristine exterior masonry several times per month. The $425-$675 for a Level 2 inspection is minor compared to the cost of undetected deterioration.
We can clean it, but we won’t leave it in service without addressing the damage. Offset joints and cracked tiles create gaps where creosote accumulates in inaccessible pockets and where combustion gases can escape into the structure. Cleaning alone doesn’t fix the hazard. We’ll document the damage with photos, explain your repair or relining options, and provide upfront pricing for the complete solution. Our 90-Day Done Right Promise covers the full repair, not just the cleaning.
Only if it was properly relined at the time of furnace replacement. In most Mount Prospect homes we inspect, it was not. The oversized flue runs too cold, causing the creosote and moisture problems we described. We can clean the existing flue and install a correctly sized DuraFlex or HeatShield liner to make it safe for fireplace use. This is one of the most common corrections we make in the neighborhoods near Randhurst Village and along Elmhurst Road.
Original clay tile liners in Mount Prospect’s 1950s-1975 housing stock are now at or well past their designed service life. In this specific climate, with repeated freeze-thaw cycling and the thermal stress of combination flue use, we consider 50 years a practical maximum for reliable performance. Many are still standing, but “still standing” is not the same as “safe.” Spalling, cracking, and mortar loss accelerate sharply after the 50-year mark. If your home dates to this era and the liner has never been inspected with a camera, it’s time.
