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.

AfterTrusted Chimney Repair for Crystal Lake Homeowners
Chimney Repair in Crystal Lake typically costs between $350 for minor mortar repointing and $4,500 for partial rebuilding, with most jobs completed in one to two days. Since 2009, Emberly Chimney Cleaners Crystal Lake has completed more than 38,000 chimney inspections and repairs across McHenry County, and we bring that same documented, camera-verified approach to every repair we quote. Call us at (815) 923-3185 for a free written estimate with your price, scope, and warranty spelled out before any work begins.
Crystal Lake’s freeze-thaw cycles are hard on masonry. Water seeps into hairline cracks in fall, expands when temperatures drop below 20°F, and opens those cracks to structural width by spring. We’ve repointed chimneys in Coventry, rebuilt crowns near Three Oaks Recreation Area, and waterproofed flues throughout the Colby and Canterbury neighborhoods. Every repair starts with a Level 2 camera inspection down the flue, so we name what we found, show you the photo record, and give you a written price before anyone picks up a trowel. That’s Clause 1 of the Haven Standard: have it in writing.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar Repointing is the removal of deteriorated mortar between bricks and its replacement with new, matched mortar to restore structural integrity and water resistance. In Crystal Lake, we see accelerated mortar decay in homes built during the 1980s and 1990s construction boom, particularly in the Wakefield and Woodland Heights areas where lime-based original mortars have softened after 30-plus winters. Our crews grind out failed joints to a uniform depth, match the sand and Portland cement ratio to your existing mortar color and hardness, and finish with a concave or struck profile that sheds water. Every repointing job includes a written specification of joint depth, mortar type, and curing time, plus the photo record required by Clause 4 of the Haven Standard.
Spalling Brick Repair
Spalling Brick Repair addresses what happens when the face of a brick flakes or pops off due to water trapped inside freezing and expanding, leaving the softer inner body exposed to further damage. Crystal Lake’s clay-heavy soils and north-facing chimneys that stay shaded and damp through March create ideal conditions for spalling, especially on homes near the Fox River basin where groundwater is high. We remove spalled bricks, inspect the wythe behind for moisture damage, install proper weep ventilation if needed, and replace with matching brick from our network of regional suppliers. If the damage is isolated to the top few courses below a failed crown, we’ll show you the camera footage of the flue interior to confirm the liner is still sound before we quote brick work alone.
Chimney Waterproofing
Chimney waterproofing is the application of a vapor-permeable silane or siloxane sealant to masonry surfaces, allowing moisture inside the brick to escape while blocking liquid water from entering. This is not the same as painting; standard exterior paint traps moisture and accelerates freeze-thaw damage, which is why we see so many failed DIY jobs in Crystal Lake’s Four Colonies and Lakewood subdivisions. We use commercial-grade treatments from suppliers in our Haven buying network, apply them only when the masonry is dry and temperatures are above 40°F, and back the application with a written performance period. Waterproofing is often the most cost-effective repair we quote, and we’ll tell you directly when it’s sufficient versus when brick replacement is the honest recommendation.
Flashing Repair
Flashing is the sheet metal assembly where the chimney passes through the roof, designed to channel water away from the joint; when it corrodes, lifts, or was never properly step-flashed during original construction, leaks follow. In Crystal Lake, we find failed flashing on a disproportionate number of homes with dimensional shingle roofs installed in the 2000s, when kickout flashings were often omitted at roof-wall intersections. Our crews fabricate custom step flashing and counterflashing from copper or painted steel, integrate it with your existing roofing underlayment, and seal with high-temperature polyurethane sealant rated for chimney applications. We photograph the completed assembly from the roof and attic side for your record, and the written warranty covers both materials and workmanship.
Chimney Rebuilding
Chimney rebuilding is the partial or complete dismantling and reconstruction of the chimney structure, required when multiple systems have failed or the stack has leaned, shifted, or lost structural connection to the house. We’ve rebuilt chimneys in Crystal Lake after vehicle impacts, after long-ignored spalling left walls one brick thick, and after improper liner installations created thermal stress cracks through multiple courses. Our rebuilds include a new concrete crown with proper drip edge and expansion control, stainless steel chimney cap, and option to upgrade to a DuraFlex or Olympia Chimney liner if the original terracotta is compromised. Every rebuild quote itemizes demolition, disposal, scaffolding, masonry, and finishing in separate line items so you see where your money goes.
Tuckpointing
Tuckpointing is a specialized form of repointing that uses two contrasting mortar colors to create the illusion of very fine, uniform joints, historically used on high-end brickwork and increasingly requested by Crystal Lake homeowners in historic districts and custom homes. The technique requires more labor than standard repointing because each joint is finished twice: first with a mortar matching the brick body, then with a thin line of contrasting mortar to simulate the joint. We maintain separate lime putty and colored mortar stocks for tuckpointing work, and we’ll show you sample boards on site before committing to the color match. Not every chimney justifies tuckpointing cost, and we’ll say so directly if standard repointing will perform identically for your application.

Brands We Service for Chimney Repair
We repair and rebuild chimneys fitted with components from the manufacturers we source through our Haven buying network. For HeatShield cerfractory flue resurfacing systems, we’ve completed hundreds of installations and restorations in McHenry County since adding the product line in 2014; the factory-trained application process requires specific surface preparation and curing protocols that our technicians are certified to execute. Gelco chimney caps and accessories are our standard for replacement installations after rebuilds or when existing caps have corroded beyond repair, and we stock common sizes for same-day fitting on Crystal Lake jobs.
Copperfield chimney supply components, including firebrick, refractory mortar, and specialty flue products, round out our material inventory for rebuilds requiring matched historical materials or high-heat applications. Whether your chimney was originally built with these brands, retrofitted by a previous owner, or uses any other make of cap, crown, or liner, we can source compatible repair materials and document the compatibility in your written scope. Our 365-Day Done Right Promise applies regardless of brand.
BeforeAfterSigns You Need Chimney Repair Right Now
- White efflorescence or dark staining on exterior brick - Efflorescence is the white powder left when water evaporates through masonry and deposits mineral salts; dark staining indicates organic growth from persistent moisture. Both mean water is getting past your crown, cap, or mortar joints and cycling through freeze-thaw damage inside the brick. In Crystal Lake, we see this most on chimneys with original concrete crowns that cracked after 15 years without maintenance.
- Chunks of brick or mortar in your yard or fireplace - Spalled brick faces and deteriorated mortar don’t always stay in place; gravity and wind remove them. Finding debris at the chimney base or inside the firebox means the protective outer layer of your masonry is gone, and the structural wythe behind it is now exposed to the same damage cycle. This is not cosmetic; the chimney’s load-bearing capacity is compromised.
- Water stains on ceiling drywall near the chimney - A leak at the chimney-roof intersection often travels along rafters before appearing on ceiling surfaces, so the visible stain may be feet from the actual failure point. Flashing leaks worsen rapidly during Crystal Lake’s spring snow melt and fall rain patterns, and the associated moisture can damage insulation, framing, and finished surfaces beyond the chimney itself.
- Smoke drafting poorly or entering the room - Poor draft can indicate a blocked flue, but it can also signal structural damage: a shifted chimney, separated flue liner, or deteriorated smoke chamber that no longer funnels combustion gases efficiently. If your fireplace worked fine last season and now smokes into the room, the change suggests a new structural problem rather than simple creosote buildup.
- Visible leaning or separation from the house - A chimney that tilts away from the structure or shows a widening gap at the roofline has lost foundation support or structural connection. This is a safety issue; the chimney’s weight is no longer distributed as designed, and collapse risk increases with each freeze cycle. We assess lean with plumb lines and photograph the gap width for your record before quoting stabilization or rebuild options.
Our Chimney Repair Process - Step by Step
- 1
Schedule your Level 2 inspection. Call (815) 923-3185 and speak with a live person, any time of day. We’ll confirm your Crystal Lake address, ask about the symptoms you’ve observed, and schedule a technician arrival with a text notification when they’re en route. Your technician arrives in uniform with license information visible and a background check on file.
- 2
Camera-scan documentation of the full system. We run a high-resolution camera the full length of your flue liner, inspect the smoke chamber, firebox, damper, and exterior masonry from roof and ground, and photograph all findings. This is not a flashlight glance; it’s the NFPA 211 Level 2 inspection standard, and we’ve performed it on every job since 2009. The footage and stills become your documented photo record under Haven Standard Clause 4.
- 3
Written diagnosis and price before any work. Within 24 hours of inspection, you receive a written scope naming each finding in plain language, the recommended repair for each, line-item pricing, and the warranty terms. Clause 1 of the Haven Standard requires this written price before work starts; we do not begin repairs on the same visit as inspection so you have time to review without pressure.
- 4
Repair execution with progress documentation. Once you approve the scope, we schedule repair work with the same technician who inspected your chimney when possible. For rebuilds and extensive repointing, we photograph key stages: mortar mix consistency, joint depth verification, flashing integration, and final assembly. You’re welcome to observe, and we explain what we’re doing as we work.
- 5
Final inspection, photo record delivery, and warranty activation. After completion, we run the camera again to verify flue integrity was preserved through the repair process, deliver your final photo record and written warranty documentation, and activate your 365-Day Done Right Promise. If anything isn’t right, we make it right. That’s stamped on every job.
How Much Does Chimney Repair Cost in Crystal Lake?
Most chimney repairs in Crystal Lake fall into these ranges based on what we’ve quoted over the past three years:
| Repair Type | Typical Range | What Affects Price |
|---|---|---|
| Mortar repointing (partial) | $350 - $900 | Height, scaffold need, mortar type match |
| Mortar repointing (full chimney) | $1,200 - $2,800 | Surface area, joint depth, brick condition |
| Spalling brick replacement (localized) | $600 - $1,500 | Brick availability, wythe damage behind |
| Chimney waterproofing | $400 - $800 | Surface area, prep cleaning needed |
| Flashing repair/replacement | $500 - $1,400 | Roof pitch, material (steel vs. copper), decking repair |
| Crown repair or replacement | $800 - $2,200 | Size, reinforcement, overhang design |
| Partial chimney rebuild | $2,500 - $4,500 | Courses affected, liner status, scaffold complexity |
| Full chimney rebuild | $5,500 - $12,000+ | Height, materials, liner replacement, permit requirements |
Three factors push Crystal Lake repairs toward the higher end of these ranges. First, the city’s 1980s-2000s housing stock often has chimneys built with lower-grade mortar that requires more extensive removal. Second, two-story and split-level homes common in the Canterbury and Coventry areas need scaffolding that single-story ranch jobs don’t. Third, McHenry County’s permit requirements for structural rebuilds add inspection fees and timeline that simple repairs avoid.
To avoid overpaying, get a second opinion on any estimate over $2,000. We offer free second opinions on competitor written quotes, and we’ll show you our camera footage so you can compare findings. Every estimate we provide includes exactly what’s included, what’s excluded, and what conditions would trigger a change order. No surprises.

Frequently Asked Questions - Chimney Repair in Crystal Lake
Chimney repair fixes structural and waterproofing failures in the masonry, metal, or liner systems; a chimney sweep removes combustible deposits from the flue interior. You might need both: we often discover repair needs during a sweep inspection, and we always recommend sweeping before major repairs so the flue is clean for camera documentation. Call (815) 923-3185 and we can schedule either service or a combined appointment.
Most single-element repairs like repointing, flashing replacement, or waterproofing are completed in one working day. Partial rebuilds and extensive tuckpointing typically require two days plus curing time before the chimney can be used. We give you a specific timeline in your written scope, and we don’t quote same-day completion for jobs that genuinely need two days just to get the sale.
Typical repairs range from $350 for localized repointing to $4,500 for partial rebuilding, with full rebuilds starting around $5,500, though how much Chimney Repair costs depends on your specific situation. Your exact price depends on what the camera inspection reveals about masonry condition, liner status, and access complexity. We provide written, line-item pricing before any work begins, and estimates are free. Call (815) 923-3185 to schedule yours.
Yes. We’re trained and equipped to repair, resurface, and replace HeatShield cerfractory flue liners and DuraFlex stainless steel liner systems, and we source both brands through our Haven buying network. If your chimney has one of these liners and needs repair, we’ll inspect it with the same camera documentation we use for all flue evaluations and quote only what’s necessary.
We answer calls live 24 hours a day, 7 days a week, and we prioritize active leaks, storm damage, and structural concerns that create immediate safety issues. For non-emergency repairs, we schedule within three to five business days. When you call, we’ll ask enough questions to determine whether your situation needs same-day assessment or can safely wait for a standard appointment.
Every repair is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right. Specific materials carry manufacturer warranties as well; HeatShield resurfacing, for example, includes a 20-year limited warranty when applied to factory specifications. Your written scope names all applicable warranties, and we retain your photo record so warranty claims don’t depend on your memory of the work.
Clear a path to your fireplace and move any furniture or decor within six feet of the hearth. For exterior work, ensure we can access the driveway or yard with our scaffold and mortar mixing equipment; trim back branches that overhang the chimney if possible. We’ll cover floors and furniture with drop cloths, but the clearer the workspace, the more efficiently we can work and the less disruption to your home.
