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.

AfterChimney Cleaning in McHenry, IL
Chimney cap and crown work in McHenry runs $180-$2,800 depending on whether we’re sealing a hairline crack or pouring a new concrete crown. Most McHenry calls we get start with water dripping into the firebox after the first hard freeze, which is why we book crown inspections heavily from March through May. Call (331) 200-4445 and we’ll send a written price before anyone picks up a trowel.
Why McHenry Homes Are Different
McHenry sits at the southern end of the Chain O’Lakes and along the Fox River, meaning a substantial share of the housing stock consists of 1920s-1950s seasonal lake cottages that have been converted to year-round primary residences. These structures were built with minimal or unlined chimneys intended for occasional use, not continuous winter heating loads.
McHenry County averages among the highest annual snowfall totals in the Chicago metro area, and the proximity to the Fox River and Chain O’Lakes introduces persistent ground-level moisture that accelerates spalling and mortar-joint deterioration on exposed brick chimneys. The extended freeze-thaw season - often running October through April - means water that infiltrates crown cracks in fall can fragment masonry significantly by spring.
Vacation cottages left unoccupied through shoulder seasons are prime nesting sites. Chimney swifts, raccoons, and squirrels move in over summer; owners who return in October and light the first fire of the season without a sweep are a recurring emergency-call pattern for our McHenry technicians.
Our Main McHenry Services
McHenry homeowners call us most often for these three services:
Chimney Cleaning & Sweep in McHenry
We clean and inspect chimneys across McHenry’s mixed housing stock, from unlined cottage flues to factory-built zero-clearance units in 1990s subdivisions. Every sweep includes an NFPA 211 Level 2 camera inspection and a documented photo record under Haven Standard Clause 4. Chimney Cleaning & Sweep in McHenry covers seasonal cottages that need pre-occupancy sweeps and year-round homes on regular maintenance cycles.
Chimney Repair in McHenry
Freeze-thaw damage, spalling brick, and deteriorated mortar joints are the bulk of our McHenry repair work, especially on converted lake cottages with exposed chimneys. We quote every repair in writing before work starts, with photos of the damage and a scoped fix. Chimney Repair in McHenry includes crown rebuilding, tuckpointing, and structural stabilization.
Fireplace Services in McHenry
Gas insert conversions in older McHenry cottages require careful venting analysis - the original flue was sized for atmospheric drafting, not a sealed combustion unit. We inspect, measure, and document what will work before quoting any modification. Fireplace Services in McHenry handles installs, troubleshooting, and safety checks.

Before
AfterChimney Cap & Crown in McHenry
McHenry’s converted lake cottages and mid-century ranch homes share a common vulnerability: concrete crowns poured decades ago with no overhang and no drip edge, plus exposed brick that takes the full force of Chain O’Lakes moisture. The freeze-thaw cycle here fragments crowns faster than inland suburbs, and squirrels nesting in uncapped flues over summer is a routine discovery our technicians document on camera. Chimney Cap & Crown work is the single most effective preventive investment a McHenry homeowner can make.
Crown Repair
Signs you need it
Water stains on the firebox ceiling, crumbling concrete at the crown edge, or hairline cracks that widen after winter.
What it costs in McHenry
Crown repair in McHenry typically runs $450-$1,200 for crack sealing and partial rebuilds, while full crown replacement ranges $1,500-$2,800.
How we do it
We grind out cracked concrete to sound substrate, form and pour new high-strength crown with proper slope and drip edge, then photograph the finished profile for your record.
Cap Installation
Signs you need it
Twigs or animal droppings in the firebox, rust streaks down the exterior brick, or a flue that has never had a cap.
What it costs in McHenry
Single-flue cap installation in McHenry ranges $180-$450; multi-flue caps or custom sizes run $400-$950 installed.
How we do it
We measure each flue precisely, select a stainless steel or copper cap with proper mesh clearance, and secure it with masonry anchors rated for McHenry wind exposure.
What Chimney Cap & Crown Costs in McHenry
| Item | Typical range in McHenry |
|---|---|
| Single-flue cap installation | $180 - $450 |
| Multi-flue cap installation | $400 - $950 |
| Crown crack repair / coating | $450 - $1,200 |
| Full crown replacement | $1,500 - $2,800 |
How long does a crown repair last in McHenry?
A properly poured crown with correct slope and overhang lasts 20-30 years even in McHenry’s freeze-thaw climate; coating-only repairs need re-inspection every 3-5 years. We note the method in your written warranty so you know which you received.
Can a chimney cap stop animals?
A correctly sized cap with 3/4-inch mesh stops squirrels, raccoons, and birds while allowing smoke and gases to vent freely; we verify mesh clearance against your appliance type before installing. Call (331) 200-4445 for exact sizing on your flue.
Chimney Liner & Rebuild in McHenry
McHenry’s converted lake cottages were built with unlined or single-wythe brick chimneys never meant for daily heating loads, and the terracotta liners in postwar ranches are now 60-70 years old. Continuous winter use in a structure designed for weekend fires creates creosote buildup, drafting problems, and elevated carbon monoxide risk that a camera inspection reveals. Chimney Liner & Rebuild is often the only safe path forward once the original liner fails.
Stainless Steel Liner
Signs you need it
Flue tiles cracked or missing chunks visible on camera, or a gas insert venting into an unlined masonry chimney.
What it costs in McHenry
Stainless steel liner installation in McHenry ranges $2,200-$4,500 depending on flue height, diameter, and whether the chimney needs relining for wood, gas, or oil.
How we do it
We measure the flue with a video scan, order DuraFlex or Olympia Chimney liner cut to length, insulate and drop it from the top, then connect a new collar and cap with photo documentation.
Partial Rebuild
Signs you need it
Spalled brick above the roofline, a leaning stack, or mortar joints eroded to finger-width gaps.
What it costs in McHenry
Partial chimney rebuilds in McHenry typically run $3,500-$7,500 for above-roof restoration; full rebuilds below the roofline range $8,000-$15,000.
How we do it
We scaffold to the roofline, remove damaged courses to sound masonry, lay matching brick with proper bond, and install a new crown and cap before the scaffold comes down.
What Chimney Liner & Rebuild Costs in McHenry
| Item | Typical range in McHenry |
|---|---|
| Stainless steel liner installation | $2,200 - $4,500 |
| Flexible liner (offset flues) | $2,800 - $5,200 |
| Partial rebuild (above roofline) | $3,500 - $7,500 |
| Full chimney rebuild | $8,000 - $15,000 |
Does every old chimney in McHenry need a liner?
Not every one - an NFPA 211 Level 2 camera inspection determines if the existing terracotta is intact and properly sized for your appliance; we show you the footage before quoting any liner work. Call (331) 200-4445 to schedule the inspection.
Can a partial rebuild wait until spring?
Above-roof spalling without structural lean can sometimes wait if the crown is sound and water entry is controlled; we document the risk in writing and note it for re-inspection. If the stack leans or mortar is missing, we recommend immediate stabilization.
