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.

We know Glen Ellyn’s chimneys. The Lake Ellyn neighborhoods, the Craftsman blocks near the Metra station, the Colonial Revivals along Pennsylvania Avenue - these aren’t abstract addresses for us. They’re homes built between 1900 and 1940 with original full-brick chimney stacks, clay tile flue liners, and shared two-flue configurations that modern suburbia simply doesn’t replicate. Our Chimney Repair team has inspected thousands of them. When a Glen Ellyn homeowner calls, we already understand what we’re likely to find.
Why Level Two Chimney Hoffman Estates Is Glen Ellyn’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections and Chimney Cleaning & Sweep - Glen Ellyn services since 2009, every one with a written price before work started and a documented photo record when finished. Glen Ellyn homeowners account for a significant share of our DuPage County workload, and the pattern is consistent: pre-war masonry, shared flues, separation tile failures. We’ve built our local reputation on naming what we find, showing it on camera, and quoting the fix in writing.
Our reviews from Glen Ellyn customers consistently cite the same details - the technician texted when en route, the camera footage was explained in plain terms, the written price matched the final invoice. Background-checked, uniformed crews with license information displayed on every page. Live phone support 24 hours a day, 7 days a week. No voicemail, no web-form black hole.
Response time to Glen Ellyn is typically 3-5 business days for standard repairs, faster for active water infiltration or structural concerns. We coordinate dispatch from our Chicago office and route crews through Glen Ellyn’s village center, Lake Ellyn area, and the Pennsylvania Avenue corridor in single-day blocks to keep scheduling tight.
What builds trust here is specificity. We don’t say “your chimney needs work.” We say: the clay separation tile between your fireplace flue and furnace flue has a three-inch crack at the third course, visible on camera at timestamp 2:14, and here’s the written price to rebuild it. That’s Clause 4 of the Haven Standard - documented photo record on every visit - and we’ve practiced it since 2009.
Our Chimney Repair Services in Glen Ellyn
Mortar Repointing
Glen Ellyn’s 80-100-year-old masonry chimneys lose mortar joints to DuPage County’s freeze-thaw cycles at rates faster than post-war brick in Carol Stream or Glendale Heights. Sitting well inland, Glen Ellyn gets none of Lake Michigan’s moderating effect - often 30 or more freeze-thaw cycles per season. We grind out deteriorated joints to proper depth and repoint with color-matched Type N or Type O mortar, depending on the original brick hardness. A typical repointing job on a Glen Ellyn two-story stack runs $1,200-$2,800.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic on Glen Ellyn’s exposed upper chimney courses. Water penetrates through failed mortar or porous brick, freezes, expands, and shears off the face. We remove spalled units, source matching brick through Haven’s buying network, and rebuild courses where structural integrity is compromised. On a 1926 Colonial Revival near Lake Ellyn, our tech found spalling so advanced on the south face that four courses required partial rebuild, not just repointing. The buyer’s inspector signed off after we documented the repair with pre- and post-camera scans.
Chimney Waterproofing
Glen Ellyn’s clay-rich soils and flat topography create chronic capillary moisture issues at chimney bases, while wind-driven rain attacks the upper stack. We apply vapor-permeable waterproofing agents - not sealers that trap moisture - to let the masonry breathe while repelling liquid water. Critical on homes near Lake Ellyn where groundwater is consistently high. Waterproofing a standard Glen Ellyn stack runs $450-$850, including minor crack prep.
Flashing Repair
Step flashing and counterflashing on Glen Ellyn’s older homes often consist of original galvanized steel, 40-60 years past service life. We replace with copper or lead-coated copper, custom-formed to the roof pitch and chimney profile. Poor flashing is the leading cause of interior water damage we see in Glen Ellyn’s pre-war housing stock - not crown failure, not cap absence, but flashing that separated from the brick during the last hard freeze.
Chimney Rebuilding
When spalling, mortar loss, and liner degradation compound past the point of spot repair, partial or full rebuild becomes the only sound option. We rebuild to current code with proper clearance to combustibles, often converting shared two-flue stacks to separated stainless systems where the original clay separation tiles have failed. A partial rebuild of a Glen Ellyn two-flue stack typically runs $3,500-$6,500; full rebuilds with new liner systems range $6,500-$12,000.
Tuckpointing
For Glen Ellyn homeowners with historically significant masonry, we offer traditional tuckpointing - the practice of cutting fine grooves into flush mortar joints to simulate the appearance of gauged brickwork. More cosmetic than structural, but appropriate for landmark-quality homes in the village center where historical integrity affects property value.

Common Chimney Repair Problems We See in Glen Ellyn Homes
- Cracked clay separation tiles in shared two-flue stacks. On 1920s-30s homes near the Metra corridor, the tile dividing the fireplace flue from the furnace flue cracks from a century of differential thermal expansion. Home inspectors flag this so routinely that it now triggers camera inspections before closing. The breach lets flue gases cross between systems - a carbon monoxide risk, not merely an efficiency problem.
- Spalling upper courses from freeze-thaw exposure. Glen Ellyn’s 30+ annual freeze-thaw cycles attack brick faces on chimneys that have never been waterproofed. The south and west exposures deteriorate fastest. We see this on virtually every unlined stack over 75 years old in the Lake Ellyn area.
- Third-degree creosote glazed inside aging terracotta liners. These chimneys served as primary heat sources for decades before modern HVAC. The resulting tar glaze - Class III creosote - cannot be removed by brushing alone. It requires chemical treatment or liner replacement, confirmed by camera inspection under NFPA 211 Level 2 standards.
- Deteriorated crowns with improper overhang or no drip edge. Original crowns on Glen Ellyn’s pre-war chimneys were often poured with too little Portland cement, no reinforcement, and no slope for water runoff. They crack, flatten, and funnel water directly into the stack below. Crown rebuild with proper overhang and drip edge is standard in our repair sequences.

What moves a job toward the higher end: access difficulty (steep roof pitch, tight lot lines common in Glen Ellyn’s older neighborhoods), extent of hidden deterioration revealed during camera inspection, and code upgrades required when converting shared flue systems. What keeps costs controlled: catching problems during annual inspection before spalling requires rebuild rather than repointing.

FAQs - Chimney Repair in Glen Ellyn
We inspect the clay separation tile between the two flues with a camera scan, looking for cracks that let exhaust gases cross from the furnace side to the fireplace side or vice versa. We also check liner condition, creosote class, crown integrity, and clearance to combustibles on both flues. This specific shared-stack configuration is far more common in Glen Ellyn’s Metra-corridor housing than in post-war suburbs, and it’s the single most frequent issue our Chimney Repair team documents here. Call (331) 200-4445 to schedule - estimates are free.
Glen Ellyn sits far enough inland that Lake Michigan’s temperature moderation doesn’t reach it, exposing brick to the full severity of Chicago-area winters - 30 or more freeze-thaw cycles annually. Combined with an 80-100-year housing stock that predates modern waterproofing practices, this produces spalling rates we simply don’t see at comparable levels in better-sheltered or newer communities. Annual inspection catches it before rebuild becomes necessary.
Yes - especially in Glen Ellyn’s shared two-flue stacks. The furnace or boiler flue continues operating regardless of fireplace use, and the separation tile between flues deteriorates from thermal cycling, not just creosote exposure. NFPA 211 recommends annual Level 2 inspection for all active chimney systems. Our camera documentation gives you a dated record of condition change year over year. Call (331) 200-4445 to book.
We verify that the original flue is properly sized and lined for the gas appliance’s lower exhaust temperature and moisture content. Many Glen Ellyn conversions were done without proper liner downsizing, leading to condensation damage in the original terracotta. We document the existing configuration with camera scan, then quote appropriate liner work - often a flexible stainless insert from DuraFlex - before any modification. The written price includes all materials and warranty terms.
No - not reliably, and not in a way that meets NFPA 211 Level 2 standards. Third-degree creosote presents as a hard, shiny, tar-like glaze that can look like normal staining from above. The camera reveals its thickness, extent, and whether it’s actively obstructing the flue. In Glen Ellyn’s pre-war chimneys with decades of pre-HVAC wood burning, we find third-degree glaze hidden behind first-degree soot layers with disturbing regularity. Clause 4 of the Haven Standard requires this documentation on every visit - we’ve practiced it since 2009.
