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.

Why Level Two Chimney Elmhurst Is Downers Grove’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 DuPage County’s older suburbs. Downers Grove homeowners know what we find because we show them - every visit includes a camera-scan inspection and documented photo record under Haven Standard Clause 4, running continuously since we started the practice in 2009.
Our reviews from Downers Grove customers consistently cite the same thing: the technician named what was wrong, showed the camera footage, and handed over a written price before asking for a decision. No voicemail loops, no “call for a quote,” no tech already in your living room before you see a number. Live phone support answers 24/7, and you’ll get a text when your technician is on the way with a name and ETA.
Dispatch and scheduling are coordinated from our Chicago office, but crews serve Downers Grove locally and carry the specific materials - DuraFlex liners, HeatShield resurfacing products, Olympia Chimney components - that older DuPage chimneys actually need. We know the difference between a 1920s Craftsman near Fairview Avenue and a 1960s split-level off 63rd Street, and we know the chimneys in those houses fail differently.
Our Chimney Repair Services in Downers Grove
Mortar Repointing
In Downers Grove’s pre-WWII neighborhoods - the Victorian clusters around Main Street, the Craftsman blocks near the Fairview Metra station - the original lime mortar in chimneys was never designed to survive decades of gas-condensate saturation. We grind out failed joints to proper depth and repoint with mortar matched to the original formulation, not modern Portland-heavy mixes that trap moisture and accelerate spalling. A typical mortar repointing job on a Downers Grove chimney runs $1,200-$2,800.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in Downers Grove’s older housing stock because the Chicago metro freeze-thaw cycle crosses 32°F dozens of times each winter, working on porous brick that was already compromised by acidic condensate from mid-century gas conversions. We remove spalled brick, source matching replacements through our Haven buying network, and rebuild with proper bonding patterns. Spalling brick repair in Downers Grove typically costs $850-$2,400 for localized repair, $3,500-$6,500 if the damage extends through multiple courses.
Chimney Waterproofing
Waterproofing a Downers Grove chimney starts with understanding that the water isn’t always coming from where you think. On unlined single-wythe stacks, condensate from gas appliances soaks the brick from the inside while rain works from the outside. We apply vapor-permeable sealants - never film-forming coatings that trap moisture - after repairing all active leaks. Chimney waterproofing in Downers Grove runs $650-$1,400 depending on accessibility and surface area.
Flashing Repair
The junction between chimney and roof is where most active leaks start, and on Downers Grove’s older homes the original flashing was often lead or galvanized steel that has fatigued through decades of thermal cycling. We fabricate custom flashing from modern materials and integrate it properly with your roofing system. Flashing repair in Downers Grove typically costs $450-$1,100.
Chimney Rebuilding
When mortar wash-out and spalling have compromised structural integrity - common on unlined chimneys where decades of condensate have destroyed the inner wythe - partial or full rebuild becomes necessary. We rebuild with proper liner integration, matching brick where possible, and always with a written scope and warranty before work begins. Chimney rebuilding in Downers Grove ranges from $4,500 for a partial rebuild to $12,000+ for a full stack replacement with new liner system.
Tuckpointing
Tuckpointing in Downers Grove addresses the cosmetic and structural degradation of mortar joints that haven’t yet progressed to full spalling. It’s preventive maintenance on chimneys that still have sound brick but failing joints - exactly the condition we find on well-maintained pre-WWII homes in the neighborhood around Washington Park. Tuckpointing runs $900-$2,200 in this market.

AfterTrusted Brands We Service in Downers Grove
We source materials through Haven’s buying network specifically to keep customer prices honest: DuraFlex stainless steel liners for relining unlined coal-boiler flues, HeatShield cerfractory resurfacing for restoring deteriorated flue surfaces without full liner replacement, and Olympia Chimney components for caps, dampers, and termination systems. These aren’t upsell items - they’re the specific products that solve the specific failure patterns we find in Downers Grove’s 1880s-1920s housing stock. We stock common sizes locally, so repairs that require custom-fabricated components still move fast.
Common Chimney Repair Problems We See in Downers Grove Homes
- Unlined single-wythe brick saturated with acidic condensate. On a Craftsman near the Fairview Avenue station, we opened the cleanout on a 1910s coal-boiler flue and found the brick spongy and efflorescent with decades of acid condensate from the gas furnace that was vented into it in the 1950s. A camera run showed the unlined single-wythe stack had no flue liner at all, so we installed a DuraFlex liner sized to the furnace and repaired the washed-out mortar at the crown. Had this been caught before the mortar gave way, the rebuild would not have been necessary.
- Freeze-thaw spalling on pre-WWII chimneys. The DuPage County freeze-thaw cycle - crossing 32°F repeatedly through winter - exploits every crack in porous brick and lime-mortar joints. We see this most on chimneys in the historic Main Street corridor where the original construction has never been properly maintained.
- Mid-century gas conversions with hidden deterioration. When Downers Grove homes converted from coal to gas in the 1950s-1970s, many chimneys were patched rather than properly relined. The damage sits below the roofline, invisible until a camera inspection reveals it. Any quote given from the ground or roofline alone is guesswork.
- Crown collapse from mortar wash-out. Water infiltration through deteriorated mortar joints undermines the chimney crown from below. We catch this early on annual cleanings; left alone, it progresses to structural rebuild territory.

FAQs - Chimney Repair in Downers Grove
You need a camera inspection to know for certain - unlined single-wythe brick chimneys are common in Downers Grove’s pre-WWII housing stock, but the condition sits entirely below the roofline and is invisible from the outside. During a Level 2 inspection, we push a camera the full length of the flue and document what we find; if there’s no clay tile liner and the brick shows efflorescence or sponginess from decades of gas condensate, we’ll show you the footage and explain your options. Call (708) 498-3199 to schedule - estimates are free.
The damage is probably coming from your gas furnace or water heater, not the fireplace. In Downers Grove’s 1880s-1920s homes, chimneys were sized for coal boilers with large, hot flues; when gas appliances were vented into those same oversized stacks in the mid-20th century, the flue ran cold and produced acidic condensate that ate the mortar from the inside. You don’t need fire to destroy a chimney - you need the wrong appliance in the wrong flue. A camera inspection during cleaning reveals the actual condition. Call (708) 498-3199 and we’ll show you what you’re dealing with.
Tuckpointing is appropriate when the brick itself is sound and only the mortar joints have failed; a full or partial rebuild is necessary when spalling has compromised the brick faces or when mortar wash-out has undermined structural integrity. We make this distinction based on camera evidence and physical inspection, not from the roofline or ground. In Downers Grove, we often find that what looks like surface spalling from the outside masks deeper deterioration inside unlined stacks - so we always inspect before recommending. Call (708) 498-3199 for a free assessment with written options.
A Level 2 inspection under NFPA 211 includes a visual examination of accessible portions of the chimney exterior and interior, plus a camera scan of the flue interior, with a documented photo record of findings - this is Haven Standard Clause 4, and we’ve done it on every visit since 2009. For any Downers Grove chimney repair, you need this level of documentation because the critical damage on older chimneys is hidden below the roofline. No repair quote from Level Two is issued without it. Call (708) 498-3199 to book.
A proper chimney cap and vapor-permeable waterproofing help, but they cannot fix an already compromised structure - and on unlined chimneys, the bigger problem is often internal condensate, not external rain. The DuPage County freeze-thaw cycle will exploit any existing crack or porous surface, so prevention starts with annual cleaning and inspection to catch mortar degradation before water enters. We install Gelco and Olympia Chimney caps as part of integrated repair plans, never as standalone miracle solutions. Call (708) 498-3199 and we’ll assess what your chimney actually needs.
