We’ve been working on Northlake chimneys since the early 1980s. Our crews know the postwar brick bungalows along Grand Avenue, the modest ranches off North Avenue, and the split-levels near the Franklin Park border. These houses were built fast during the 1950s and 1960s boom, and their chimneys tell a consistent story: originally sized for oil or coal, later converted to natural gas, often left with oversized flues that never got properly lined. That fuel-conversion legacy is the defining chimney problem in Northlake. It is not a footnote. It is the reason so many Northlake homeowners call us after another company did a “standard sweep” and missed the actual problem.
Our Chimney Cleaning & Sweep team carries the equipment to assess liner condition, not just brush out soot. In Northlake, that distinction matters.
Why Hearthstone Chimney Co. of Chicago Is Northlake’s Preferred Chimney Cleaning & Sweep Company
Northlake homeowners have left us reviews for decades. We do not chase ratings, but we do read every one. The pattern is consistent: technicians who show up on time, explain what they found in plain English, and leave photos the homeowner can see. Our 90-Day Done Right Promise is in writing, with no arguing. If it is not right, we come back.
We answer the phone with a live person, 24 hours a day, 7 days a week. Not a voicemail. Not a callback queue. A real person who can dispatch a technician to Northlake.
Our response time to Northlake averages under 45 minutes because our Chicago-based crews know the local streets: North Avenue, Grand Avenue, the industrial corridor near the rail yards, and the residential grid between Wolf Road and 25th Avenue. We do not waste time with GPS guesses.
Local knowledge builds trust. We know that a chimney on a 1958 brick bungalow near the old Hawthorne Works site probably shares a flue between furnace and water heater. We know that freeze-thaw damage from Chicago’s continental winters hits Northlake’s soft lime mortar harder than the harder mortars used in newer construction. We know what to look for before we ring the doorbell.
Our Chimney Cleaning & Sweep Services in Northlake
Level 1 Inspection
A Level 1 inspection is the standard annual check for chimneys with no known changes. In Northlake, we perform these on well-maintained systems, but we rarely stop there. The 1950s and 1960s housing stock here means most chimneys have been altered, converted, or patched. Our Level 1 includes visual assessment of accessible portions, but our technicians are trained to flag when a Level 2 is warranted. Most Northlake homes we visit need that deeper look.

Level 2 Inspection
This is where our Northlake work gets specific. A Level 2 inspection uses a video camera to examine the full length of the flue, the smoke chamber, and the firebox. We document every finding with photos you can see and a plain-English verdict. In Northlake, we are looking for the damage pattern that comes from oversized flues: acidic condensation eating mortar joints, spalled clay tiles, and gaps between liner sections. We serviced a 1950s brick bungalow on Hazelwood Avenue where a shared flue for a gas furnace and water heater had deteriorated from acidic condensation. Our crew installed a DuraFlex liner and performed a Level 2 inspection, resolving persistent carbon monoxide risks and poor draft. The homeowner had lived there 34 years and never known the flue was shared until we showed her the camera footage.

Creosote Removal
Creosote buildup is a chimney fire hazard, and Northlake’s long heating season, October through March, produces significant loads by late winter. But here is the local complication: oversized flues from fuel conversions burn cooler than properly sized flues. Cooler flue gases condense more readily, and that condensation mixes with creosote to form a corrosive, tar-like glaze that standard brushing often misses. Our creosote removal in Northlake uses professional-grade rotary systems and, when necessary, chemical treatments to break down glazed deposits. We do not leave until the flue is clean and we have verified liner integrity. A dirty flue with a failing liner is not a finished job.

Soot Removal
Soot removal sounds simple. In Northlake, it rarely is. Soot in a converted gas flue often signals incomplete combustion, which means the appliance is not venting properly through that oversized chimney. We remove the soot, but we also diagnose why it accumulated. Sometimes the fix is a thorough cleaning. Sometimes it is a liner installation with HeatShield or DuraFlex materials. Sometimes it is reconfiguring a shared flue that never should have been shared. We tell you which before we start.

Annual Sweep
Northlake’s freeze-thaw cycles and heavy winter chimney use make annual sweeping a practical necessity, not a calendar decoration. We schedule these to minimize disruption, complete most in a single visit, and leave the system documented for next year’s comparison.

Fireplace Cleaning
Many Northlake homeowners use their fireplaces as supplemental heat during the coldest weeks. Our fireplace cleaning removes ash, soot, and debris from the firebox, smoke shelf, and damper assembly. We check for proper draft and flag any signs of water intrusion from cracked crowns or failed flashing. A clean fireplace that drafts poorly is a CO risk. We fix both.

Trusted Brands We Service in Northlake
We stock parts and materials from Copperfield, DuraFlex, and HeatShield, among other professional-grade brands. For Northlake homeowners, that means faster turnaround.

Common Chimney Cleaning & Sweep Problems We See in Northlake Homes
- Oversized flues from fuel conversion accumulate acidic condensation, rapidly degrading mortar and liners. Northlake’s chimneys were built for oil or coal and later converted to natural gas. The flue is too large for the lower-temperature gas exhaust. Moisture condenses on the walls, mixes with combustion byproducts, and forms acid that eats mortar and clay tiles from the inside out. A standard sweep brushes the surface but does not stop the chemical attack.
- Shared flues for furnace and water heater create poor draft and CO backdraft risks. This was common 1960s installation practice in Northlake. Two appliances vent into one oversized flue. Neither drafts efficiently. Carbon monoxide can spill into the basement during startup or windy conditions. Our Level 2 camera inspection finds these configurations, and our liner installations separate or properly size the venting.
- Unlined or poorly lined flues after oil-to-gas conversion accelerate creosote buildup and chimney fire hazards. Many Northlake conversions were done without proper liners. Raw masonry exposed to gas exhaust deteriorates, and the rough surface traps creosote. The result is a higher fire risk in a flue that was already marginal. We assess liner condition every time we sweep.
- Freeze-thaw cycling spalls brick and cracks crowns, letting water into the system. Northlake sits in Chicago’s full continental zone. Subfreezing nights, thawing days, repeated all winter. Water enters hairline cracks, expands when it freezes, and widens them. By March, a small crown crack can become a major leak. Our inspections catch this early, before spring rains compound the damage.

FAQs - Chimney Cleaning & Sweep in Northlake
Yes, almost certainly. The original flue was sized for oil or coal combustion, which runs hotter and produces more draft. Natural gas exhaust is cooler and wetter. Without a properly sized liner, condensation forms on the oversized flue walls, mixes with combustion byproducts, and creates acid that destroys mortar and clay tiles. We find this damage in most unlined Northlake chimneys within 20 years of conversion. Call (888) 289-6055 for a Level 2 inspection and liner assessment. Estimates are free.
Look for moisture or rust stains on the flue pipe in the basement, a persistent sulfur or rotten-egg smell near the appliances, or a water heater that backdrafts when the furnace starts. These are warning signs of poor draft in an oversized shared flue. Carbon monoxide is the silent risk. We identify shared flues during our Level 2 camera inspection and can separate or reline the venting. Call (888) 289-6055 if you notice any of these symptoms.
Water enters cracks in the crown, mortar joints, or brick face. When temperatures drop below freezing, that water expands and widens the cracks. Repeated cycles through a Northlake winter can spall brick faces and loosen crowns. Annual sweeping removes soot and creosote that trap additional moisture against the flue walls, and our inspection identifies crown and mortar damage before spring rains make it worse. The cleaning is preventive maintenance. The inspection is what saves you from a rebuild. Call (888) 289-6055 to schedule before the next freeze.
A Level 2 inspection. Ranch homes on North Avenue were built during Northlake’s peak construction years with the same fuel-conversion chimney systems as the bungalows. The flue was likely oversized for the conversion, may be shared between appliances, and has 60-plus years of wear. A Level 1 visual check cannot assess internal liner condition or hidden flue damage. Our Level 2 camera inspection gives you photos, a plain-English verdict, and a documented baseline. Call (888) 289-6055 to book.
Yes. This is specialized work we perform regularly in Northlake. Oversized flues burn cooler, which produces more condensate and a stickier, more corrosive creosote glaze. Standard wire brushing often fails to remove it. We use rotary mechanical systems and, when necessary, professional-grade chemical treatments to break down the deposit. After removal, we assess whether the flue needs resizing or relining to prevent rapid reaccumulation. Call (888) 289-6055 for an inspection and exact quote. Estimates are free.
