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.

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.

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

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
