Fast, Reliable Chimney Liner & Rebuild Across Catonsville
Chimney liner replacement and chimney rebuilds in Catonsville typically cost between $1,800 and $6,500 depending on scope, and most projects are completed in a single day with our crew. If your flue is cracked, your liner is sized wrong for a converted gas system, or your chimney crown has failed after another freeze-thaw winter, we’ll diagnose it with a Level-2 camera inspection and give you a plain-English verdict you can see for yourself.
We’ve been working in Catonsville since 1984, and we know the chimneys here. The Colonial Revivals along Frederick Road, the Cape Cods tucked behind Edmondson Avenue, the bungalows in the older grid near the historic core - these houses were built with oversized masonry flues designed for coal and oil, not modern gas appliances. That fuel-conversion mismatch is the single most common reason Catonsville homeowners call us for liner work. When you’re ready, a live person answers our phones at (844) 803-1545, twenty-four hours a day.
Why Hearthstone Chimney Co. Is Catonsville’s Preferred Chimney Liner & Rebuild Company
Catonsville homeowners tend to stay put. The 21228 ZIP has one of the higher rates of long-term residency in Baltimore County, and we’ve found that people who’ve owned their house for twenty-five years don’t want a sales pitch. They want someone who will look at the chimney, explain what’s actually wrong, and fix it without creating a new problem. That’s why our Level-2 camera inspections end with photos you can see and a written verdict - documented like an engineer, explained like a craftsman.
Our technicians are background-checked, uniformed, and complete most liner and rebuild jobs in a single visit. We offer no-hassle upfront pricing, so the number on the estimate is the number on the invoice. And every job is backed by our 90-Day Done Right Promise in writing - if it’s not right, we come back, no arguing, no paperwork chase. Over forty-two years, that approach has built a reputation we don’t take lightly.
Calls are answered by a live person, not a queue or an app, every hour of every day. When a chimney is backing up smoke or a liner has failed mid-winter, that matters.
Our Chimney Liner & Rebuild Services in Catonsville
Stainless Steel Liner Installation
Stainless steel liners are the right choice for most Catonsville oil-to-gas conversions and wood-burning restorations. We size the liner to the appliance, not the existing flue, which is critical in these 1920s-1950s homes where the original clay tile liner is far too large for modern equipment. A properly sized stainless liner from Olympia Chimney or Famco eliminates the acidic condensation that silently erodes mortar in oversized flues. Most installations run $2,200-$3,800 in Catonsville and are completed in one day.
Flexible Liner Installation
Flexible liners navigate offsets and bends that rigid pipe cannot, making them essential for chimneys with corbelled shoulders or angled flues common in the older masonry around Catonsville’s historic core. We’ve installed flexible liners in bungalows where the chimney tilts with the roofline and in Colonials with multiple direction changes. The material is professional-grade, not builder-grade, and we back the installation with our 90-Day Done Right Promise. Typical cost in Catonsville: $2,000-$3,500.
Liner Replacement
When clay tile liners crack or spall - which we see regularly after hard freeze-thaw winters in Catonsville’s elevated, exposed position west of Baltimore - replacement is often the only safe option. We remove the damaged liner and install a new system sized to your current heating appliance, whether that’s a gas furnace, oil boiler, or wood insert. This is not a patch job. A liner replacement in Catonsville typically costs $1,800-$3,200, and we handle the full scope: inspection, removal, installation, and final camera verification.
Partial Chimney Rebuild
Partial rebuilds address the top courses of brick, the crown, and the flue surround without dismantling the entire stack. In Catonsville, this is often the right solution for chimneys where the north and west faces have deteriorated faster than the south face due to persistent shade and moisture retention from the mature oak canopy. We rebuild with matching brick where possible and install a proper concrete or Gelco crown with correct overhang and drip edge. Partial rebuilds in Catonsville generally run $3,500-$6,500 depending on height and access.

Trusted Brands We Service in Catonsville

When we inspect your chimney, we know what parts are available and what the timeline actually is. No builder-grade substitutes, no surprises on the bill, and every component is documented in your written report.
Common Chimney Liner & Rebuild Problems We See in Catonsville Homes
- Oversized flues from fuel conversions. The Colonial Revivals and Cape Cods throughout 21228 were built with flue diameters for coal or oil. When homeowners converted to gas without resizing the liner, the reduced exhaust temperature caused acidic condensation that erodes clay tile from the inside out. We find this in roughly half the pre-1960 chimneys we inspect in Catonsville.
- Freeze-thaw spalling on chimney crowns and brick faces. Catonsville’s elevation west of Baltimore exposes chimneys to harsher wind and more rapid temperature oscillation in December through February. Water penetrates the crown, freezes, expands, and pops the brick face off the wall. Homeowners who skip a post-winter inspection are often shocked how much damage one season creates.
- North- and west-face deterioration from canopy shade. The mature oak and maple canopy in Catonsville’s older neighborhoods keeps masonry damp for days after rain. We regularly find the north and west faces of a chimney stack in significantly worse condition than the south face on the same structure - a pattern you wouldn’t see in a cleared, new-construction suburb.
- Failed mortar joints between clay flue tiles. In chimneys that vented oil for decades before gas conversion, the acidic exhaust degraded the mortar bedding between flue tiles. The gaps allow exhaust gases to leak into the chimney cavity, and in a lined system, they indicate the original liner is no longer protecting the masonry. This is a common finding in our Catonsville Level-2 inspections.
