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.

Why Level Two Chimney Naperville Is Montgomery’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a growing share of those are coming from Montgomery’s 2000s-era subdivisions where factory-built fireplaces are hitting their first major service interval. Our technicians know the difference between a Heatilator refractory panel and a Majestic chase assembly because we’ve replaced both in Montgomery homes - not once, but dozens of times.
Montgomery customers find us through referrals from Naperville and West Chicago, then stay because we show them camera footage of their flue before quoting a dollar. Reviews consistently mention the text-ahead arrival, the uniformed tech with a name, and the written price that doesn’t change after the ladder goes up.
Response time to Montgomery runs 3-5 days for standard repairs; urgent water intrusion or exposed framing gets prioritized same-week. We know which side of Orchard Road puts you in Kendall County versus Kane, and we verify jurisdiction before pulling permits so your job doesn’t stall.
The Haven Standard governs everything we do: Clause 1 requires a written price before work starts, Clause 4 requires a documented photo record on completion, and our 365-Day Done Right Promise means if it’s not right, we make it right.
Our Chimney Repair Services in Montgomery
Mortar Repointing
In Montgomery’s original village core along the Fox River, early-to-mid 20th century brick chimneys have absorbed decades of river-valley moisture. Freeze-thaw cycling here is more aggressive than in elevated communities like Wheaton because cold air settles in the valley and moisture wicks deeper into mortar joints. Repointing a Montgomery masonry chimney runs $18-$32 per square foot of joint, and we grind to sound substrate before laying new Type N or Type S mortar matched to the original. We document before-and-after with photos under Haven Standard Clause 4.
Spalling Brick Repair
Spalling - the flaking or crumbling of brick faces - shows up first on south- and west-facing chimney exposures in Montgomery, where daily freeze-thaw in late winter pops the surface off saturated brick. River-valley humidity keeps masonry wet longer here than in drier western suburbs. Individual brick replacement runs $45-$85 per brick including matching and installation; partial rebuilds of damaged courses start around $680. We always inspect the crown and flashing first, because spalling without fixing the water source is a temporary repair.
Chimney Waterproofing
Montgomery’s position in the Fox River valley means ground moisture pushes through foundation walls and chimney bases year-round, not just during spring rains. We apply vapor-permeable silane/siloxane sealers to masonry chimneys - $380-$620 for a typical two-story flue - that let the wall breathe while blocking liquid water. For prefab chases in subdivisions like Brentwood, we inspect and replace rusted chase covers with stainless or copper from our Famco and Copperfield inventory, then reseal chase flashing. Waterproofing without a camera inspection first is guesswork, so we include the Level 2 scan in every quote.
Flashing Repair
Flashing is where most Montgomery chimney leaks start, especially on the 2004-2007 subdivision homes where step flashing was often installed fast and without kickout diverters. We remove siding courses, install new copper or galvanized step and counterflashing, and integrate proper water management - $420-$780 for standard repair, $890-$1,400 if surrounding sheathing needs replacement. Because Montgomery straddles the Kane/Kendall county line, the same flashing repair scope can require a permit from one building department on one side of town and a different inspection regime on the other. Our crews confirm jurisdiction before ordering materials so your job doesn’t sit in administrative limbo.

AfterTrusted Brands We Service in Montgomery
We stock parts from DuraFlex, HeatShield, and Copperfield through Haven’s buying network, which keeps customer prices honest and turnaround short. For Montgomery’s concentration of 15-20-year-old factory-built fireplaces, that means we can source Heatilator refractory panels, Majestic chase covers, and Lennox gaskets without the multi-week special-order delay that sends homeowners to big-box stores for incompatible substitutes. HeatShield’s cerfractory resurfacing system is our go-to for restoring eroded smoke chambers in older Montgomery masonry chimneys without a full rebuild. Every part is documented in your photo record with serial numbers where applicable.
Common Chimney Repair Problems We See in Montgomery Homes
- Cracked refractory panels in never-serviced gas log fireplaces. In River’s Edge and Brentwood, we regularly open 2005-2007 zero-clearance boxes to find refractory panels cracked and chase covers rusted through. The owners never knew - nothing looks wrong from the living room. Heat reaches framing through those cracks. We replace panels and caps, then run a Level 2 inspection to confirm the flue liner and damper are still sound.
- Loose prefab chase flashing from boom-era installation. Fasteners installed during the 2004-2007 construction rush have worked loose after 15+ winters of expansion and contraction. Water tracks down the chase into wall framing. We remove the chase cap, reseat and refasten flashing, and replace deteriorated sealant with proper through-wall flashing where needed.
- Assuming newer means maintenance-free. Factory-built fireplaces have panels, gaskets, and flue liners that still need Level 1 or Level 2 inspection. A cracked refractory panel in a 2006 Heatilator is as dangerous as deteriorated mortar in a 1926 brick chimney - the failure mode is different, but the fire risk is real.
- Crown deterioration accelerated by valley moisture. Montgomery’s river-valley location keeps crowns wet longer after rain, and freeze-thaw opens cracks faster than in drier, higher suburbs. We pour new concrete crowns with proper overhang and drip edge, or apply HeatShield CrownCoat for minor cracking - always after confirming the flue liner condition with a camera scan.

FAQs - Chimney Repair in Montgomery
Yes, most chimney repair beyond cleaning requires a permit, and the issuing department depends on which side of the Kane/Kendall county line your home sits. Montgomery straddles both counties, so our crews verify jurisdiction before ordering parts or scheduling inspections - a prefab chase cap replacement in a River’s Edge home might need Kendall County approval while the same job two blocks east falls under Kane. We handle permit research as part of every quote. Call (331) 265-1700 and we’ll confirm which building department governs your address.
Because factory-built fireplaces have a designed service life, and 15-20 years is when refractory panels crack, gaskets fail, and chase covers rust through. In River’s Edge, we opened a 2005 zero-clearance Heatilator-style box running a gas log set the owners had never serviced: the refractory panels had cracked and the chase cover had rusted through, so we replaced the panels and cap, then ran a Level 2 inspection and confirmed the flue liner and damper were still sound. The point for newer Montgomery homes is that nothing looks old from the curb - the failure is inside the factory-built firebox and up on the prefab chase. Call (331) 265-1700 for a camera inspection; estimates are free.
Every wood-burning chimney needs annual inspection under NFPA 211, and in Montgomery’s extended heating season - roughly October through April - creosote accumulates heavily. Gas fireplaces should be inspected every 1-2 years, and factory-built units at the 15-year mark even if they’ve performed fine. The freeze-thaw cycling and valley moisture here accelerate deterioration compared to drier climates. Call (331) 265-1700 to schedule; we include a documented photo record with every inspection under Haven Standard Clause 4.
First-degree creosote is flaky and sooty, brushes off easily, and indicates dry wood and hot fires - common early in the season. Third-degree creosote is hard, glossy, and tar-like; it forms when wood burns cool and incomplete, and it can’t be removed with standard brushing - it requires rotary chains or chemical treatment. In Montgomery, third-degree buildup is common because homeowners damp down fires for overnight burns during long winter cold snaps, and because river-valley humidity keeps flue temperatures lower. Third-degree creosote is the leading cause of chimney fires. We classify what we find with photos, then quote removal before any work starts. Call (331) 265-1700 if you can’t remember your last cleaning.
Yes - completely different systems, different failure modes, and often different parts availability. River’s Edge and Brentwood homes typically have zero-clearance metal fireboxes with refractory panels, chase enclosures, and factory-specified caps rather than brick-and-mortar construction. Repairs require manufacturer-compatible parts, not generic masonry materials, and the inspection focuses on panel integrity, gasket seals, and chase weatherproofing rather than mortar joints or crown condition. Our crews carry Heatilator, Majestic, and Lennox component inventory specifically for these Montgomery subdivisions. Call (331) 265-1700 - we’ll identify your unit and quote from the correct parts list.
