Wood Fireplace Specialists in the Northwest Suburbs
GEM Chimney & Duct specializes in wood-burning fireplace repair for homeowners throughout Wheeling, IL and the northwest Chicago suburbs. We service both masonry fireplaces — built with brick, mortar, and firebrick — and prefabricated (factory-built) fireplaces with refractory panels and metal components. Whether your firebox has cracked mortar joints, your damper is stuck, or your fireplace is pushing smoke into the room, we start with a thorough inspection, give you a written report with photos, and provide an upfront written estimate before any work begins.
Safety Note: Cracked Firebox Mortar Is a Hidden Fire Hazard
Cracked mortar joints inside the firebox are not a cosmetic issue. The mortar between firebricks is the only barrier between the intense heat of a fire and the framing and insulation behind the firebox walls. When those joints deteriorate, heat can transfer directly to combustible materials — a hidden fire hazard that can smolder for hours before igniting. If you've noticed cracked or missing mortar inside your firebox, have it inspected before using the fireplace again. GEM provides written inspection reports documenting the exact condition of the firebox so you know what you're dealing with.
Wood Fireplace Repairs We Handle
Firebox Tuckpointing
Repointing deteriorated mortar joints between firebricks with refractory mortar rated for high-heat applications. This is the most common firebox repair and restores the fire barrier between the firebox and surrounding structure.
Firebox Rebuilds
When firebrick is severely spalled, cracked, or structurally compromised, a partial or full firebox rebuild replaces the damaged brick and mortar. We use firebrick and refractory mortar rated for the application.
Refractory Panel Replacement
Prefab (factory-built) fireplaces use cast refractory panels instead of brick. These panels crack over time and must be replaced — not patched. We stock or source replacement panels for most major prefab fireplace brands.
Damper Repair and Replacement
Throat dampers (inside the firebox) and top-sealing dampers (at the top of the flue) both wear out. A stuck or missing damper costs you heat all winter. We repair or replace both types.
Smoke Chamber Parging
The smoke chamber above the damper is often rough, corbelled masonry that creates turbulence and draft problems. Parging (coating) the smoke chamber with refractory mortar smooths the surface and improves draft.
Hearth and Lintel Repair
The hearth extension and the steel lintel above the firebox opening both take structural stress over time. We repair cracked hearths and replace failed or sagging lintels.
Spark Screen and Door Repair
Damaged or missing spark screens and glass doors are a safety issue. We repair or replace fireplace doors and screens to restore the safety barrier between the fire and your living space.
What We Find in Older Northwest Suburb Homes
Most homes in Wheeling, Arlington Heights, Northbrook, and the surrounding northwest suburbs were built between the 1950s and 1990s. Wood-burning fireplaces in these homes have often been in use for 30–60 years with little or no professional maintenance. The most common issues we find in these older fireplaces are: firebrick that has spalled or cracked from decades of thermal cycling, damper plates that have rusted shut (causing heat loss all winter) or rusted open (making the fireplace unusable), and smoke staining on the wall above the fireplace opening — a visible sign of a draft problem that's been going on for years. These are all repairable. The key is getting an accurate diagnosis before spending money on the wrong fix.
Our Repair Process
Level 1 or Level 2 Inspection
We begin with a Level 1 inspection (visual examination of accessible areas) or a Level 2 inspection with camera for more complex situations. This determines the exact condition of the firebox, damper, smoke chamber, and flue before we recommend any repairs.
Written Report with Photos
You receive a written report documenting every issue found — with photos. This gives you a clear record of the fireplace's condition and the basis for any repair recommendations.
Upfront Written Estimate
After the inspection, we provide a written estimate covering all recommended repairs. You approve the scope before any work begins. No surprise charges.
Repair with Rated Materials
All firebox repairs use materials rated for high-heat applications — refractory mortar, firebrick, and refractory panels sourced from our regional suppliers. We don't use standard masonry materials inside a firebox.
