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 serve Downers Grove from our Chicago dispatch office, with crews covering the historic downtown triangle, the mid-century ranch belts near Ogden Avenue, and the north-side neighborhoods along 63rd Street. Our technicians carry the trade’s real vocabulary and the camera equipment to show you what we find before any work starts. Downers Grove’s housing stock is unlike its neighbors - dense pre-war attached homes with shared stacks, oversized coal-era flues, and 80-100 years of freeze-thaw damage - and that specificity is what our Chimney Repair team trains for.
Why Level Two Chimney Joliet Is Downers Grove’s Preferred Chimney Repair Company
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a surprising share of our repair calls originate in Downers Grove’s older neighborhoods where a routine sweep turns into a structural conversation. The reason is simple: this village’s pre-1940 housing wasn’t built for modern venting, and the 1950s conversions compounded the problem.
Our Downers Grove customers leave three-star reviews when we flag something they didn’t expect, and five-star reviews when we show them the photo evidence and the written price before anyone picks up a trowel. That’s the Haven Standard - Clause 1 requires a written scope and price before work starts, Clause 4 requires a documented photo record on every job. No exceptions.
Calls are answered by a live person, 24 hours a day. We text when your technician is en route, and every crew is background-checked, uniformed, and licensed. Corrine Halstead built this practice into the company from day one.
We know the local permitting landscape. DuPage County jurisdictions vary, and Downers Grove’s building department has specific requirements for chimney rebuilds and liner installations that our office handles directly.
Our Chimney Repair Services in Downers Grove

Mortar Repointing
Mortar repointing in Downers Grove runs $1,200-$2,800 for a typical two-story masonry chimney, with price driven by access difficulty and how many courses need grinding out. The freeze-thaw cycle here is brutal - temperatures swing from sub-zero January nights to 90-degree summer days, and north- and west-facing chimneys absorb the worst of it. We grind out failed joints to proper depth, match the original mortar composition for thermal compatibility, and tool each joint to shed water. On homes near the downtown Metra corridor, we’ve repointed chimneys where the original 1920s lime mortar had turned to powder behind intact-looking face joints - a condition camera inspection reveals before the bricks start dropping.

Spalling Brick Repair
Spalling - where freeze-thaw cycles pop the face off a brick - is epidemic on Downers Grove’s pre-war chimneys. Repair costs $950-$2,200 depending on how many courses need replacement and whether the damage traces to a failed crown or flashing. We source matching brick through our Haven buying network when possible, and we always address the water source that caused the spalling. Otherwise you’re repairing the same chimney twice. Our crews have replaced spalled courses on Victorians near Belmont Road and Foursquares along Forest Avenue, always with photo documentation of the underlying structure before we close it up.

Chimney Waterproofing
Chimney waterproofing in Downers Grove costs $650-$1,400 and buys you the single most cost-effective protection against the repair spiral. We apply vapor-permeable sealers - never film-forming coatings that trap moisture - specifically formulated for Chicago-area masonry. The application includes crown sealing, flashing inspection, and a written condition report. For north- and west-facing chimneys in Downers Grove, we recommend waterproofing as preventive maintenance every five to seven years, or immediately after any repointing or rebuild. The alternative is watching a $1,200 waterproofing job turn into a $4,000 rebuild because the water kept getting in.

Flashing Repair
Flashing repair runs $450-$1,100 in Downers Grove, with step flashing replacement on the higher end and simple counterflashing reseal on the lower. The intersection where your chimney penetrates the roof is the most common leak point we find during inspections, and on older Downers Grove homes with multiple roof layers, the flashing is often buried under decades of shingle. We remove to inspect, replace with copper or lead-coated copper from our Copperfield and Gelco inventory, and photograph the deck condition underneath. If your chimney is on a west-facing slope catching prevailing weather off the prairie, this repair is not optional - it’s structural triage.

Chimney Rebuilding
Full or partial chimney rebuilding in Downers Grove ranges $3,500-$8,500 depending on height, access, and whether the flue needs relining simultaneously. We rebuild with matching brick, proper crown construction with drip edges and expansion joints, and new flue liners sized correctly for your appliance - not the coal-era oversize that created the problem. Every rebuild includes a written warranty, photo documentation at footing and completion, and smoke testing when shared stacks are involved.

Tuckpointing
Tuckpointing - the decorative and functional replacement of weatherstruck or flush mortar joints - runs $1,400-$3,200 in Downers Grove. On historic homes near the downtown triangle, we match original joint profiles and color to preserve architectural integrity while restoring water resistance. The work is slower than standard repointing and requires a steady hand, but the result is a chimney that looks original and performs like new.

Common Chimney Repair Problems We See in Downers Grove Homes

- Shared or adjacent flues in dense downtown-triangle housing. On attached Victorians and Foursquares near the Metra corridor, one masonry stack often served multiple fireplaces and was later tied into gas furnace or water-heater venting. A repair on one address can change draft and spillage for the neighbor sharing the stack - a condition we test and document, not guess at.
- Coal-era oversized flues converted to gas without relining. These high-draft, large-diameter flues built for coal furnaces produce chronic condensation and poor draft when adapted to 80% efficient gas appliances. Standard creosote-focused cleaning leaves the root cause untouched; only proper relining with a correctly sized DuraFlex or HeatShield system solves it.
- Freeze-thaw destruction of north- and west-facing masonry. DuPage County’s winter temperature swings - repeated cycles of wetting, freezing, and thawing - accelerate mortar joint failure and brick spalling. Chimneys on these exposures in Downers Grove routinely need repointing, waterproofing, and crown rebuilds every 15-20 years.
- Failed chimney crowns with no drip edge or expansion joint. Original crowns on pre-war Downers Grove chimneys were often poured flat or sloped toward the flue, with no overhang to shed water. We rebuild with proper pitch, drip edges, and expansion joints that accommodate thermal movement without cracking.

FAQs - Chimney Repair in Downers Grove

Yes. A shared stack means any change to flue diameter, liner condition, or draft characteristics on one side can alter performance for the neighbor’s appliance. We smoke-test shared stacks after repair to confirm no backdrafting or spillage occurs. On an 1890s Foursquare near the downtown Metra corridor, our tech pulled the damper and found the clay flue liner had cracked and stepped, with second-degree creosote glazing above a coal-era oversized flue that had been converted to a gas water heater without relining. We repointed the firebox mortar, installed a HeatShield liner, and rebuilt the chimney crown and cap, then smoke-tested the shared stack to confirm the neighbor’s appliance wasn’t back-drafting into this home. Call (815) 620-5234 if you suspect shared-stack issues - we document everything under Haven Standard Clause 4.
Standard cleaning removes creosote and obstructions but does not change flue diameter or thermal properties. An oversized coal-era flue is too large for a modern gas appliance’s lower exhaust temperature and reduced draft; the result is sluggish venting, condensation, and chronic moisture damage. The fix is relining with a correctly sized DuraFlex stainless steel or HeatShield cerfractory liner, not another cleaning. We measure your appliance output and flue geometry during our Level 2 inspection, then specify the liner size in writing. Call (815) 620-5234 for a camera inspection that shows you the mismatch.
Downers Grove’s housing stock is 30-50 years older on average, with pre-WWII masonry chimneys that predate modern liner requirements and 1950s-70s conversions that compounded flue mismatches. Chicago-area freeze-thaw cycles hammer these systems harder every winter than they do newer construction. In Woodridge and Lisle, you’re more likely to find properly lined, independently vented chimneys built to 1980s+ codes. Here, a cleaning call routinely uncovers cracked liners, failed mortar, and spalling brick that demand repair before the chimney is safe to use. That’s why we bring the camera on every visit - so you see what we see, not just hear about it. Call (815) 620-5234 to schedule.
A Level 1 inspection is a visual check of accessible portions - adequate for annual maintenance on chimneys with no changes. A Level 2 inspection, which we perform on every Downers Grove repair evaluation, includes camera-scan documentation of the full flue interior, accessible attics and crawl spaces, and written findings with photos - this is the NFPA 211 standard that became Haven Standard Clause 4 in 2009. A Level 3 inspection involves demolition of building components to access concealed areas, reserved for suspected structural failures or fire damage. Most Downers Grove repairs begin with Level 2; we only recommend Level 3 when camera evidence justifies it, and we show you that evidence first. Call (815) 620-5234 to book a Level 2 inspection.
DuPage County’s winter temperature swings - repeated cycles of wetting, freezing, and thawing - force water trapped in masonry to expand and contract, cracking mortar joints, spalling brick faces, and splitting concrete crowns. North- and west-facing chimneys in Downers Grove accumulate damage fastest because they stay wet longer and catch prevailing weather. Flashing sealants degrade faster under thermal stress, and crowns without proper drip edges or expansion joints fail predictably within 10-15 years. Annual inspection before heating season catches this damage before it reaches the structure. Call (815) 620-5234 for a pre-winter camera inspection and written condition report.
