Professional Chimney Relining
Protect your home from carbon monoxide and chimney fires with premium UL-listed stainless steel lining systems—backed by a lifetime transferable warranty.
Give Your Chimney a New Lease on Life
The chimney liner is the most critical safety feature of your venting system. It contains poisonous combustion gases (like carbon monoxide) and protects surrounding masonry from intense heat and corrosive chemicals. If your clay tile liner is cracked, flaking, or missing, your home is at significant risk.
We specialize in high-quality stainless steel liners designed to withstand extreme thermal shock and last for decades. Our systems come with a Lifetime Transferable Warranty on all materials.
🏆 Lifetime Material Warranty
Our stainless steel liners are warranted for as long as you own your home—and the warranty transfers to the next owner at no cost.
Deteriorated clay liner cavity—a hidden fire and CO hazard
Why Chimney Relining Is Often Necessary
Older chimneys—especially those built before the mid-20th century—may lack a proper liner or have deteriorating clay tile. Without annual maintenance, cracked tiles, crumbling mortar, or collapsed sections allow hazardous gases, embers, and even flames to leak into living spaces.
Common causes of liner failure:
- Past chimney fires that crack or spall tiles
- Improper appliance venting (e.g., oversized wood stoves)
- Poor original construction or unlined older masonry
- Freeze-thaw moisture cycles in Maryland winters
- Age-related deterioration in homes 30+ years old
Instead of costly chimney demolition, modern stainless steel relining offers a faster, more affordable solution—sealing the flue, improving draft, and extending your chimney's lifespan.

We primarily install insulated stainless steel liners—the gold standard for durability and performance. Here are the systems we offer for every fuel type and chimney configuration.

Rigid vs. Flexible Systems
We choose the best fit for your chimney's offsets, bends, and dimensions to ensure optimal draft performance.
- Rigid for straight flues
- Flexible for offset chimneys
- Insulation wrap available
Oil-to-Gas Conversions & Liner Sizing
In Baltimore, switching from oil heat to natural gas is increasingly common for cost savings and efficiency. Local codes typically require installing a correctly sized stainless steel liner (usually 5–6 inches) to safely vent the new system.
We custom-fit the ideal liner based on your exact flue dimensions and appliance BTU rating. Every liner we install for conversions carries our factory lifetime warranty with competitive pricing that beats larger companies.
- Expert flue sizing calculations included
- Same-day installs in many cases
- Code-compliant for all MD gas utilities
Not Sure If Your Liner Is Damaged?
We use high-resolution video cameras to inspect every inch of your flue, documenting the condition before and after any service. You'll receive clear visual proof of any defects—no guesswork, no unnecessary upselling.
A Level II video inspection is especially recommended when:
- Buying or selling your home
- After any chimney fire, even a minor one
- Switching fuel types or appliances
- Experiencing draft problems or smoky fireplaces

“I had another chimney company come out before I called Stanley and they made it seem as though the job was impossible. Stanley came out and reassured me that everything was going to be ok and that the problem wasn’t nearly as serious as the other company made it out to be. He was fair and reasonable in his pricing and even laid out step by step how the work was going to be done.”
“Stan and helper installed chimney liner for a new woodstove insert, insulated liner and connected the stove. They were very professional and courteous, worked hard in bitterly cold weather and took time to ensure project completed to customer’s satisfaction. Fire burns beautifully!
