Fast, Reliable Chimney Repair Across Mount Prospect
Chimney repair in Mount Prospect typically runs $450-$3,800 depending on whether you need mortar repointing, liner replacement, or full rebuilding, and most jobs are completed in a single visit with upfront pricing. If your home was built between 1950 and 1975, your clay tile liner is likely past its service life, and the freeze-thaw cycling we get here from November through March accelerates the damage faster than in drier climates.
We’ve been driving to Mount Prospect from our Chicago base for over 42 years. We know the ranch homes along Elmhurst Road, the split-levels near Randhurst Village, and the Cape Cods tucked behind Lions Park. The original clay tile flues in these houses are now 50-70 years old, and we’re systematically relining entire blocks as homeowners discover what our Level-2 camera inspections reveal. When you call (888) 289-6055, a live person answers, day or night. We’ll schedule your free estimate, show up when we say, and give you photos you can see with a plain-English verdict.

This isn’t generic suburban housing to us. It’s a specific vintage with specific failure modes we’ve repaired hundreds of times.

Our Chimney Repair Services in Mount Prospect
Mortar Repointing
The mortar joints in a 1960s Mount Prospect ranch chimney have endured 60+ winters of freeze-thaw cycling, and by now they’re often powdering out between the bricks. We grind out the failed mortar to proper depth and repoint with color-matched, professional-grade mortar formulated for Chicago-area weather. Done right, repointing stops water intrusion and buys your chimney another 25-30 years without the cost of rebuilding. Most Mount Prospect repointing jobs run $850-$2,200 for a standard single-flue chimney.
Spalling Brick Repair
Spalling, the flaking and crumbling of brick faces, is nearly universal on Mount Prospect chimneys that have lost their crown integrity or were built with softer brick common to the 1950s-60s build-out. We remove damaged brick, match replacement brick for color and hardness, and rebuild the affected courses. In severe cases, particularly on chimneys serving both furnace and fireplace with decades of combined thermal stress, spalling indicates deeper structural compromise that our camera inspection will document with photos you can see.
Chimney Waterproofing
Mount Prospect sits 20 miles northwest of Lake Michigan, close enough to catch lake-effect moisture that penetrates porous masonry more aggressively than in inland suburbs. We apply vapor-permeable waterproofing sealants from professional-grade suppliers that let the chimney breathe while blocking liquid water. This is preventive work that pays off most on chimneys with sound mortar but aging brick, common in the 1970s split-levels near Kimball Hill Park.
Flashing Repair
Chimney flashing in Mount Prospect takes a beating. The combination of freeze-thaw cycling, wind-driven rain off the lake, and original step flashing installed 50+ years ago means leaks at the roofline are one of our most common calls. We replace failed flashing with new copper or galvanized step and counter flashing, integrated properly with your roofing. Sometimes the metal is sound but the sealant has cracked; we’ll tell you straight which it is, with photos, so you’re not paying for work you don’t need.
Chimney Rebuilding
When spalling, mortar failure, and liner damage compound past the point of repair, we rebuild. In Mount Prospect, this most often means the upper courses above the roofline, where weather exposure is worst, though we occasionally rebuild full-height on chimneys with catastrophic liner collapse or structural settling. We match existing brick and mortar color, install a proper concrete crown with correct overhang and drip edge, and often pair the rebuild with a new stainless steel liner from DuraFlex. A partial rebuild in Mount Prospect typically runs $2,800-$4,500; full rebuilds range $5,500-$8,500 depending on height and access.
Tuckpointing
For Mount Prospect homeowners with chimneys where the mortar is failing but the brick remains sound, tuckpointing restores the weather seal and structural integrity without the cost of rebuilding. We see this need constantly in the 1950s-60s neighborhoods where original lime-based mortar has simply reached end of life. Our tuckpointing includes grinding to 3/4-inch depth minimum, proper mortar selection for the era of construction, and cleanup that leaves your property as we found it.

Trusted Brands We Service in Mount Prospect
We don’t use builder-grade substitutes. For liner installations in Mount Prospect’s aging chimneys, we specify DuraFlex stainless steel liners for their flexibility in offset clay tile flues and their lifetime warranty. For crown repairs and refractory work, we use HeatShield and Gelco products formulated for the thermal cycling these chimneys endure. Copperfield supplies our professional-grade waterproofing and flashing materials. We stock these parts locally, so most Mount Prospect repairs don’t wait on shipping. The brands matter because a liner or crown installed with inferior materials will fail before your original clay tile would have, and we’re not in business to do jobs twice.
Common Chimney Repair Problems We See in Mount Prospect Homes
- Clay tile liner cracking and spalling from 50+ years of freeze-thaw cycling. Mount Prospect’s winter temperatures oscillate repeatedly across the 32°F threshold, forcing moisture in cracked tile to expand and contract until the liner collapses. We find this on nearly every Level-2 inspection in homes built before 1975.
- Oversized combination flues left unused after furnace upgrades. A very common find in 1960s-70s Mount Prospect homes: the original flue served both furnace and fireplace, but after the furnace was swapped for a high-efficiency unit venting through sidewall PVC, the old shared flue was never resized. The result is a chronically cold, oversized flue that accumulates heavy creosote and condensation moisture even with light use.
- Crumbling mortar joints and crown damage from decades of Chicago-area weather. The original mortar crowns on Mount Prospect chimneys were often poured too thin, without proper reinforcement or drip edges. After 50 years of thermal cycling, they crack, allow water behind the brick, and the decay accelerates.
- Flashing failure at the roofline causing interior water damage. Original step flashing on mid-century Mount Prospect homes used galvanized steel that corrodes, or was simply never integrated properly with the roofing. We see this manifest as stained drywall on cathedral ceilings in split-levels where the chimney penetrates the roof near the living space.

FAQs - Chimney Repair in Mount Prospect
Not necessarily a time bomb, but it’s almost certainly past its reliable service life. In Mount Prospect’s 1960s ranches, original clay tile flues commonly show spalling, hairline cracking, and offset joints after 60+ years of freeze-thaw cycling, and the oversized combination flue design many of these homes used compounds the problem by running too cold. We recommend a Level-2 camera inspection to see exactly what condition yours is in, documented with photos and a plain-English verdict. Call (888) 289-6055 to schedule; estimates are free.
It depends on how deep the damage goes. If the spalling is limited to the top few courses and the mortar joints below are sound, repointing and partial brick replacement will restore it. If the structural courses are compromised or the liner has collapsed, rebuilding the upper section or full height becomes the honest recommendation. We recently worked on a 1958 ranch on S George Street where the original clay tile liner had spalled and offset at the cleanout - a universal find in this neighborhood. We installed a DuraFlex stainless steel liner to correct the oversized combination flue left after the homeowner swapped the old oil furnace for a high-efficiency unit, stopping the chronic creosote buildup from that cold, oversized chimney. We’ll show you photos and tell you straight which path makes sense. Call (888) 289-6055 for an exact assessment.
You likely have an oversized flue left from a former combination furnace-and-fireplace installation. This is one of the most common finds in 1960s-70s Mount Prospect homes: after the furnace was upgraded to high-efficiency and vented through a sidewall PVC pipe, the old shared flue was never relined to the correct smaller diameter for fireplace-only use. The resulting flue is too large to stay warm, so smoke cools rapidly, condensation forms, and creosote accumulates at 2-3 times the normal rate. A properly sized stainless steel liner fixes this permanently. We can verify the flue diameter with our camera inspection and quote the correct liner installation. Call (888) 289-6055.
If the metal is sound and properly integrated with the roofing, we can reseal with professional-grade flashing cement and extend its life. More often on 50+ year-old Mount Prospect homes, the original galvanized step flashing has corroded, the counter flashing has pulled away, or the roofer who last replaced shingles cut corners on chimney integration. We replace failed components with new copper or step flashing, properly counter-flashed and sealed, because patching bad metal wastes your money. We’ll photograph what we find and explain which approach applies. Call (888) 289-6055 for a free inspection.
A partial rebuild of the above-roof portion typically runs $2,800-$4,500 for a Mount Prospect split-level, while a full rebuild from the roofline up ranges $5,500-$8,500. Split-levels often have taller chimney runs than ranches, and the roof penetration is frequently more complex, which can push toward the higher end. The exact figure depends on brick matching, liner condition, and whether we need to stage the work. We give you the full number upfront, not an estimate that doubles.
