Chimney Company in Logan Square — Flat-Price Sweep, Photo Report Included

Chimney Company in Logan Square, IL

Chimney repair in Logan Square usually means working on a masonry stack that’s been standing since before the First World War. Most of the chimneys we service here are original brick from the 1890s through the 1920s, built for coal-fired furnaces and now handling gas appliances or the occasional fireplace. The freeze-thaw cycles Chicago puts these old stacks through mean cracked crowns, spalling brick, and clay tile liners that have given up after a century of service. If you’re seeing water stains, mortar dust, or draft problems in a Logan Square two-flat or greystone, call Sandstone Chimney Sweep at (833) 589-7835 for a straight diagnosis.

Why Logan Square Homes Are Different

Logan Square’s housing stock creates a specific set of chimney problems that generic advice doesn’t cover. The neighborhood’s dense rows of 1880s – 1920s brick two- and three-flats, greystones, and frame workers’ cottages sit on narrow 25-foot lots with shared party walls and rear gangways. That means chimneys are typically at the shared wall between units, so access and exterior staging are tight. Ladders go up gangways, staging goes over garages, and the flue you’re working on often belongs to a neighbor’s unit as much as the person who called us.

The bigger issue is what’s inside those stacks. Many Logan Square chimneys were built with clay tile liners or no liner at all. After a century of coal service followed by decades of gas appliance venting, those liners are commonly cracked, spalled, or entirely missing. Chicago’s hard freeze-thaw cycles don’t help: deep winter freezes followed by midwinter thaws and damp spring weather spall and crack the original soft brick and mortar crowns. Heavy lake-effect snow and ice dams at the roofline drive water into unlined flues. And because the heating season runs from October to April, the flue is in near-constant use for most of the year.

There’s also a quirk specific to Logan Square’s two- and three-flats. A single chimney stack often serves two separate flues: one for each unit’s furnace or water heater. We routinely find the upstairs flue relined while the downstairs one is still bare clay tile, or vice versa. What looks like one chimney problem is really two heating systems sharing a century-old masonry stack.

Our Main Logan Square Services

Most Logan Square homeowners call us for one of two things: a chimney that hasn’t been cleaned in years, or a dryer vent that’s packed with lint. Both are fire hazards, and both can be handled in a single visit.

Chimney Sweep in Logan Square

Chimney sweeping in Logan Square means removing creosote and soot from flues that are often over a century old. On the neighborhood’s two- and three-flats, we sweep both flues in a shared stack, not just the one you use. The tight rear gangways and shared party walls here mean we plan access carefully before any equipment goes up. A clean flue is the baseline; a sweep also tells us whether the liner is still sound. For most Logan Square homes, an annual sweep is the minimum for safe operation through Chicago’s long heating season. Chimney Sweep in Logan Square

Dryer Vent Cleaning in Logan Square

Dryer vent cleaning is the home fire hazard most people never think about. In Logan Square, where laundry rooms are often in basements or closets far from an exterior wall, dryer ducts run long distances with turns that catch lint. That buildup restricts airflow, makes dryers run longer, and creates a real fire risk. We clean the entire duct run, from dryer to termination point, and check for crushed or disconnected sections. Bundle it with a chimney sweep and you’ve addressed two of the leading household fire hazards in a single visit. Dryer Vent Cleaning in Logan Square

Chimney Repair in Logan Square

Chimney repair in Logan Square is dominated by the neighborhood’s dense stock of late-1890s-to-1920s two- and three-flat greystones and brick workers’ cottages, many still with their original unlined or clay-tile-lined chimneys serving now-retired coal flues. So most jobs here are relining and capping chimneys built over a century ago, not sweeping modern prefab flues. The rapid turnover of these two-flats into condo conversions, and the constant gut-rehab permitting along Milwaukee and Logan Boulevard, means chimney scope is frequently caught mid-renovation, where the flue serves a newly installed furnace or water heater rather than an open fireplace. When we find a problem during a sweep, we can fix it without handing you off to another company. That matters in a neighborhood where the chimney is structural, shared, and old. Chimney Repair

Chimney Cap Installation

Signs you need it

You see birds, squirrels, or raccoons entering the flue, or you find water and debris inside the firebox after rain.

What it costs in Logan Square

A standard chimney cap installation in Logan Square typically runs $150 to $400, depending on the flue size and whether it’s a single-flue or multi-flue cap on a shared stack.

How we do it

We measure the flue tile precisely, select a stainless or copper cap sized for Logan Square’s wind and rain exposure, and secure it to the crown with mechanical fasteners, not adhesive.

Chimney Cap Replacement

Signs you need it

The existing cap is rusted through, missing, or the mesh is torn open wide enough for animals to get through.

What it costs in Logan Square

Chimney cap replacement in Logan Square falls between $150 and $450, with the cost depending on whether the old cap can be removed cleanly or the crown needs patching first.

How we do it

We remove the old cap, inspect the crown and flue tile underneath, then install a new cap rated for the specific flue dimensions and local pest pressure.

Chimney Liner Installation

Signs you need it

Your chimney has no liner, the clay tiles are cracked or missing, or you’re seeing moisture damage on interior walls near the flue.

What it costs in Logan Square

A stainless steel chimney liner installation in Logan Square generally runs $2,400 to $5,200, with the wide range reflecting flue length, story count on the two-flat, and whether the old liner must be broken out.

How we do it

We run a camera down the flue to document the exact condition, size the liner system from DuraFlex for the specific appliance and flue length, and install it with proper insulation and top and bottom terminations.

Chimney Flashing Repair

Signs you need it

You see water stains on the ceiling near the chimney, dampness in the attic, or rust streaks on the brick where the chimney meets the roof.

What it costs in Logan Square

Chimney flashing repair in Logan Square typically runs $300 to $850, depending on whether it’s a simple reseal or full replacement of the step and counter flashing at the roofline.

How we do it

We cut back the old flashing, inspect the roof decking underneath for rot, install new step and counter flashing with proper overlap, and seal the joint with a polyurethane sealant that handles Chicago’s freeze-thaw cycles.

Chimney Crown Repair

Signs you need it

The top of your chimney has cracked, spalled concrete, or the crown is missing sections so the brick below is exposed to rain and snow.

What it costs in Logan Square

Crown repair in Logan Square falls between $250 and $700, depending on whether we can patch and reseal or need to form and pour a new concrete crown.

How we do it

We remove loose material, build proper crown formwork with a drip edge that extends past the brick line, and pour a crown mix sized for Chicago’s temperature swings so water sheds away from the flue.

What Chimney Repair Costs in Logan Square

How long does chimney repair take in Logan Square?

A cap installation or crown repair is done in one visit, typically two to three hours. A full relining of a two-flat stack takes a day to a day and a half, depending on flue length and how much of the old liner must be removed. Logan Square’s tight gangway access sometimes adds staging time before we even start the work itself.

Can you fix a chimney on a shared two-flat wall without affecting the neighbors?

Yes. We work on one flue at a time, and the work is contained to the stack and roofline. If you’re in a Logan Square two-flat where the stack is shared, we’ll talk to you about which flue serves your unit so the right side gets the repair. We don’t need access to the neighbor’s unit unless their flue is the one being worked on.

Brands We Service in Logan Square

We install and service chimney systems built around specification-grade products. That means liner systems from DuraFlex and caps and dampers from Famco and Copperfield, not whatever the big-box store happens to stock. We keep common parts for Logan Square’s older masonry chimneys in inventory, so many repairs happen same-visit. For larger jobs, materials arrive from our supplier within a few days.
