Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Repair Across Naperville
Chimney repair in Naperville typically runs $350-$2,800 depending on whether you’re dealing with a rusted prefab chase cover or a full masonry rebuild, and most non-emergency jobs are scheduled within 3-5 business days. We’re the Chimney Repair team that knows Naperville’s housing stock inside out - from the prefab-heavy subdivisions off 75th Street to the historic brick chimneys near the Riverwalk. Our crews are dispatched from our Chicago office and carry DuraFlex liners, HeatShield refractory materials, and prefab chase covers sized for the Heatilator and Heat-N-Glo units that dominate this market. Call (708) 498-3199 to book a Level 2 inspection with written pricing before any work starts.
Why Level Two Chimney Elmhurst Is Naperville’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of those have been in Naperville’s 1980s-1990s subdivisions where the same prefab fireplace models fail in predictable patterns. Our Naperville customers leave reviews mentioning the same things: the tech showed up in uniform, texted when en route, and handed them a written price before touching a tool. That’s Haven Standard Clause 1 - “Have it in writing” - and it’s how we’ve operated from day one.
Our response time to Naperville is typically same-week for standard repairs, with camera-scan documentation included on every visit under Haven Standard Clause 4. We don’t do “flashlight looks.” Every flue gets a video scan, every customer gets the footage, and every recommendation is backed by photos you can see for yourself. No guesswork. No pressure to commit on the spot.
What separates us in this market is prefab expertise. Most chimney companies in the Chicago area are masonry shops at heart. They can repoint brick all day, but ask them to source a chase cover for a 1992 Heat-N-Glo SL-550 and you’ll get a blank stare. We stock parts and have supplier relationships specifically for these units because Naperville’s housing demands it.
Our Chimney Repair Services in Naperville
Mortar Repointing
Mortar repointing in Naperville runs $18-$28 per square foot for historic-district chimneys with standard lime-based mortar, and $22-$35 per square foot for harder-access stacks on two-story colonials near Naper Boulevard. The freeze-thaw cycles here are brutal. Water gets into hairline cracks in October, expands through January, and by March you’ve got spalling brick and compromised structural integrity. We grind out failed joints to proper depth, match the existing mortar composition for thermal compatibility, and document the before-and-after under Clause 4. Repointing alone won’t save a chimney with extensive spalling or a failed crown, and we’ll tell you exactly that when we see it.
Spalling Brick Repair
Spalling brick repair in Naperville’s historic core - the blocks near Jefferson Avenue and the Riverwalk - typically costs $800-$2,200 depending on how many courses need replacement and whether the damage extends to the wythe (the inner wall separating flues). Spalling happens when moisture behind the brick face freezes and pops the surface off. It’s common on chimneys with failed crowns or deteriorated pointing. We source matching brick through our Haven buying network when possible, and we never recommend brick replacement without first identifying and fixing the water source. That’s usually crown, flashing, or both.
Chimney Waterproofing
Chimney waterproofing for Naperville masonry stacks runs $450-$950 for a standard two-story application using vapor-permeable sealers that let the brick breathe. Cheap silicone sealers trap moisture and accelerate spalling; we don’t use them. For prefab units, waterproofing means chase cover replacement and chase cap sealing, typically $280-$650 depending on whether we’re working with a standard galvanized replacement or upgrading to stainless. Naperville’s shoulder seasons - those freeze-thaw weeks in late October and early March - are when water does the most damage. We schedule waterproofing calls heavily in September before the first hard freeze.
Flashing Repair
Flashing repair in Naperville costs $350-$850 for standard step-flashing replacement on a asphalt-shingle roof, and $600-$1,400 where we’re working with tile, metal, or complex chimney-to-roof intersections with a cricket (the peaked diversion structure behind wider chimneys). Naperville’s 1980s-1990s subdivisions often have builder-grade aluminum flashing that fatigues at the bend points after 20-25 years. Water stains on ceilings near the chimney breast are the tell. We fabricate custom flashing on site when needed, seal with high-temperature polyurethane, and photo-document the completed work. If your leak source isn’t the flashing, we’ll show you what is before we quote anything.
Chimney Rebuilding
Full chimney rebuilding in Naperville ranges from $3,500 for a partial rebuild above the roofline to $8,500-$14,000 for a complete tear-down and reconstruction on historic-district properties. We don’t recommend rebuilding lightly. Every rebuild proposal comes with a full Level 2 inspection, video documentation, and a written explanation of why repair isn’t viable. For prefab units, “rebuilding” often means chase reconstruction and firebox replacement rather than masonry - a different skill set that many local companies simply don’t offer. We do both.
Tuckpointing
Tuckpointing - the cosmetic refinement of repointing with contrasting mortar lines - runs $25-$40 per square foot in Naperville and is typically requested on visible historic chimneys where appearance matters as much as function. We distinguish clearly between structural repointing (necessary) and cosmetic tuckpointing (optional), and we quote them separately so you know what you’re paying for.

We stock and install DuraFlex stainless steel liners, HeatShield cerfractory flue sealant, and Gelco chimney caps through our Haven buying network, with parts availability that keeps most Naperville repairs to a single visit. For prefab chase covers and firebox panels, we source through Olympia Chimney and factory-direct channels for Heatilator, Heat-N-Glo, and Majestic units. Having the right part on the truck matters in Naperville, where a failed chase cover in January isn’t a “order and wait” situation. Our techs carry common sizes for the 1980s-1990s units that dominate subdivisions from Hobson West to White Eagle, and our Chicago office maintains next-day access to less common sizes.
Common Chimney Repair Problems We See in Naperville Homes
- Rusted-through galvanized chase covers on 1980s-1990s prefab units let water into the chase, causing firebox and damper corrosion that spreads to shared flues in attached housing. We see this pattern repeatedly in Naperville townhome clusters where multiple units share a common chase structure.
- Retrofitted gas log inserts vented into original factory-built liners not rated for gas, creating carbon monoxide migration risk into neighboring units through shared chimney chases. This is a recurring finding on inspection calls across the city’s mid-generation subdivisions, and it’s why we always check liner ratings against installed appliances.
- Freeze-thaw cycles crack mortar crowns and spall brick on historic-district chimneys near downtown, while modern prefab homes suffer crown seal failures that go unnoticed until water stains appear on ceilings. The damage mechanisms differ; the inspection protocol is the same.
- Failed chimney flashing on two-story colonials with complex roof geometry, particularly in subdivisions where builders prioritized speed over proper counter-fl integration. By the time a homeowner notices a ceiling stain, the sheathing damage is often extensive.

These ranges reflect Naperville’s market specifically - labor rates, permit requirements through the City of Naperville Building Division, and the prevalence of prefab versus masonry work. What moves a job to the higher end: access difficulty (steep roof, tight lot lines), matching specialty materials on historic properties, or discovery of concealed damage after camera inspection. What keeps it lower: straightforward swap of a standard chase cover on a single-story accessible roof. Every quote is written, itemized, and delivered before work begins. No exceptions.

FAQs - Chimney Repair in Naperville
Every year, before the first fire of the season. The NFPA 211 standard calls for annual inspection of all chimney systems, and Naperville’s 1980s-1990s prefab units are now at or past their 25-40 year design life. Galvanized chase covers rust, refractory panels crack, and factory-built dampers corrode - all on predictable timelines. Our Level 2 inspection includes a camera scan of the full flue length, documentation of chase cover condition, and verification that any retrofitted gas appliance is venting through a properly rated liner. Call (708) 498-3199 to schedule - estimates are free.
The risk is carbon monoxide migration into living space or adjacent units. Factory-built wood-burning fireplaces were never designed for gas appliance venting; their liners are sized for wood combustion temperatures and draft patterns. Gas burns cooler, produces more moisture, and requires a different liner material - typically aluminum or stainless rated for Category I gas venting. We’ve found numerous Naperville installations where gas logs were dropped into original wood-burning prefab fireboxes with no liner modification at all. That’s a hazard we document, explain with photos, and quote to fix. Call (708) 498-3199 for a Level 2 inspection if you’re unsure about your setup.
Shared chimney chases in attached Naperville housing often have deteriorating separation walls or missing wythes between flues, allowing smoke and combustion gases to migrate. The cause is usually one of three things: a rusted-through chase cover letting water damage the separation structure; a missing or damaged chimney cap allowing wind-driven down-drafting; or a liner failure creating positive pressure that pushes exhaust into adjacent flues. Our camera inspection locates the breach, and our report includes photos you and your neighbor can review together. Remediation typically involves chase cover replacement, liner repair or replacement, and sealing of separation gaps. Call (708) 498-3199 - we’ll inspect and quote in writing.
Sometimes, but not always. Repointing restores mortar joints; it doesn’t fix spalled brick, failed crowns, or compromised liners. On historic chimneys near the Riverwalk and Jefferson Avenue corridor, we often find that mortar failure is a symptom of deeper water intrusion through a cracked crown or failed flashing. Our Level 2 inspection determines whether repointing alone will solve the problem or if crown reconstruction, brick replacement, or liner work is also needed. We quote each element separately so you know exactly what you’re paying for. Call (708) 498-3199 for a camera inspection and written assessment.
A Level 2 inspection includes visual examination of accessible interior and exterior chimney components, video camera scan of the full flue length, inspection of the attic and crawl space where accessible, and documentation of all findings with photos and written report. For Naperville’s prefab-heavy housing stock, we specifically examine chase cover condition, firebox refractory panel integrity, damper operation, and liner rating against any installed appliances. For masonry chimneys, we assess crown, flashing, mortar, brick condition, and liner integrity. Every Level 2 under Haven Standard Clause 4 produces a documented photo record - not optional, not extra. The inspection fee is credited toward repair work if you proceed.
