Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Wilmette, IL
Chimney repair in Wilmette is rarely a simple patch job. Most homes here were built between the 1920s and 1960s with original clay tile flues, and decades of freeze-thaw cycles have taken a toll. We regularly find cracked liners, spalling brick, and failing crowns on Wilmette chimneys that still look fine from the street. Sandstone Chimney Sweep has served Wilmette since 2017, and we approach every repair with the same inspection-driven mindset: find the real problem, show you the evidence, then fix it with materials built to last. Call (833) 589-7835 for a free estimate.
Why Wilmette Homes Are Different
Walk any street in Wilmette, from the lakefront estates east of Sheridan Road to the colonials and Tudors farther west, and you’ll see the same thing: masonry chimneys that have been standing for 70 to 100 years. That longevity is impressive, but it comes with a catch. The original clay tile liners inside those flues were never designed for this climate, and Wilmette’s cold winters punish them relentlessly.
Freeze-thaw is the big one. Water seeps into hairline cracks in the clay, freezes, expands, and widens those cracks a little more each winter. By the time a chimney is 60 years old, those tiles are often compromised in ways you can’t see from the outside. When we clean a Wilmette fireplace, we’re not just brushing out soot. We’re looking at the liner, the damper, the crown, and the flashing, because in this housing stock, a routine sweep is often the moment a bigger problem gets caught before it becomes dangerous. That’s the difference between a company that cleans chimneys and one that knows how Wilmette homes actually age.
Lake-effect moisture adds another layer. Homes on the east side of Wilmette, particularly near the lake, get more wind-driven rain and humidity than properties a mile inland. That constant moisture accelerates spalling, the flaking and crumbling of brick faces, and it eats away at mortar crowns. By spring, we commonly see crowns with cracks wide enough to fit a quarter, and flashing that has pulled away from the roofline after repeated freeze cycles.

Our Main Wilmette Services
Most Wilmette homeowners call us for one of two reasons: they need a chimney sweep before burning season, or they need dryer vent cleaning to clear a hidden fire hazard. Both are services we handle in a single visit when needed.
Chimney Sweep in Wilmette
A chimney sweep in Wilmette is the starting point for almost every other chimney decision you’ll make this year. Beyond removing creosote and soot, our sweep includes a close look at your liner, damper, crown, and flashing, because the winter here leaves marks that matter. If we find damage, we’ll show you photos and walk you through what can wait and what can’t. For a full breakdown, see our dedicated Chimney Sweep in Wilmette page.
Dryer Vent Cleaning in Wilmette
Dryer vents clog with lint, and lint is one of the most overlooked residential fire risks. Wilmette laundry rooms are often tucked into basements with long vent runs to the exterior, which gives lint more places to accumulate. When we clean your chimney, we can clean your dryer vent in the same visit, knocking out two fire hazards at once. For details, see our Dryer Vent Cleaning in Wilmette page.

Chimney Repair in Wilmette
Chimney repair in Wilmette usually starts with a problem found during a sweep or an inspection. The original clay tile liners in these pre-war and mid-century homes crack under decades of freeze-thaw stress, and once a liner is compromised, the chimney is no longer safely containing heat and combustion gases. Add lake-effect moisture and aging mortar, and you get the most common Wilmette repair calls we see: relining, crown repair, flashing repair, and cap replacement. These are structural fixes, not cosmetic ones, and they should be handled by someone who understands how the whole flue system works together. That’s where our approach differs: we use specification-grade materials from brands like DuraFlex and HeatShield, not consumer-grade substitutes, because a repair on a Wilmette chimney should outlast the season. For more on how we approach repairs, see our Chimney Repair hub page.
Chimney Liner Installation
Signs you need it
Cracked flue tiles found during an inspection, visible clay tile pieces in your firebox, or smoke backing up into the room are all signs your liner needs replacement.
What it costs in Wilmette
Chimney liner installation in Wilmette typically runs $2,500 to $6,500 depending on flue size, liner material, and chimney height.
How we do it
We measure the flue, select a DuraFlex liner sized to your fireplace and fuel type, then lower it through the chimney, insulate as needed, and connect it at the appliance and the top plate.
Chimney Crown Repair
Signs you need it
Cracks in the concrete crown, spalling brick near the top, or water stains on the ceiling near the chimney all point to a failing crown.
What it costs in Wilmette
Chimney crown repair in Wilmette ranges from $500 to $2,000, depending on whether we patch, resurface, or pour a new crown.
How we do it
We clean the crown, fill or remove damaged concrete, apply a proper slope so water runs off, and seal it so Wilmette’s freeze-thaw cycles don’t crack it again next winter.
Chimney Flashing Repair
Signs you need it
Water leaking around the chimney base, rusted or lifted flashing, or damp drywall near the roofline mean the flashing has failed.
What it costs in Wilmette
Chimney flashing repair in Wilmette typically costs $300 to $1,200, depending on how much flashing must be replaced.
How we do it
We remove the old flashing, cut new step and counter flashing to fit, and seal the joint so lake-effect rain and snow can’t get behind it.
Chimney Cap Replacement
Signs you need it
A missing or rusted cap, rain water in the firebox, or birds and debris getting into the flue means the cap is gone or not doing its job.
What it costs in Wilmette
Chimney cap replacement in Wilmette runs $200 to $700, depending on cap size and material.
How we do it
We remove the old cap, check the flue opening for damage, and install a properly sized stainless cap that keeps water and animals out.
What Chimney Repair Costs in Wilmette
| Item | Typical range in Wilmette |
|---|---|
| Chimney cap replacement | $200 – $700 |
| Chimney flashing repair | $300 – $1,200 |
| Chimney crown repair | $500 – $2,000 |
| Chimney liner installation | $2,500 – $6,500 |
Does a cracked liner need to be replaced right away?
Not always, but often. A cracked clay liner can’t safely contain heat and gases, and Wilmette’s freeze-thaw cycles only make cracks worse. If we find cracks during a sweep, we’ll show you camera footage and tell you honestly whether it can wait or needs immediate attention.
How long do chimney repairs last in Wilmette?
When done with specification-grade materials like DuraFlex liners and proper crown resurfacing, repairs typically last 15 to 20 years or more. The variable is how much water and freeze-thaw stress the chimney sees each winter, which is why we emphasize proper drainage and sealing on every Wilmette repair.
Brands We Service in Wilmette
We stock and install parts from a focused set of professional brands: DuraFlex for liners, HeatShield for resurfacing, and Olympia Chimney for caps and dampers. Copperfield and Famco components are available for specific repairs. Because we keep these lines on hand, most Wilmette repairs don’t wait on shipping. Learn more about our brands.

In Wilmette, the two things that push a repair price up are chimney height and liner condition. Tall chimneys on two-story colonials require more setup and safety rigging, and a liner that has significantly deteriorated adds labor hours to extraction and prep. We give a flat price before any work starts, based on what we see and what you approve.

— Amanda Hayes"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
