Chimney Relining

Our Chimneys & Furnace Flue Stainless Steel Liners Last A Lifetime

The condition of the inside of the chimney venting your fireplace, stove, insert, furnace, or boiler can change over time. General wear and tear, age, and chimney leaks can cause spalling, flaking flue tiles, cracks, eroded mortar joints, gaps between tiles, and corrosion, rust, and holes if the liner is metal — and all of that damage can mean serious problems when it comes to safety and performance.

The lining of the chimney is meant to protect the masonry against the intensely hot temperatures, corrosive gases, and byproducts produced by the fire. It’s also meant to provide a smooth, airtight surface that prevents heat from transferring to framing and insulation in nearby walls (which could spark a fire), and that streamlines and speeds up the path for byproducts to exit the chimney. When damage is present, the liner can’t effectively do its job. As a result, you may be at greater risk of house fire and carbon monoxide poisoning, and your heating appliance could be wasteful and damaging to your home.

We may also recommend a reline in the following situations:

  • Following a chimney fire
  • When your liner is not appropriately sized for the appliance it’s venting
  • When your liner is not U.L. tested and approved for venting the type of appliance you have or are switching to

With over 30 years in various fields of the fire industry, there’s nothing we care about more than fire prevention. We want to make sure our customers in Columbia and all throughout Central Maryland stay safe and sound when at home, and we believe that a quality chimney liner goes a long way in ensuring that.

Chimney crowns are essentially concrete coverings for masonry chimneys. They seal Your hearth appliance’s chimney may be well taken care of, but what about your furnace or boiler flue? When neglected and damaged, this flue can be just as dangerous as the one venting your fireplace, stove, or insert. That’s why it’s important to have your furnace/boiler flue inspected annually and relined as needed.

There’s an easy way to find out if your chimney liner needs to be replaced: just call Trinity Chimney Service to schedule an inspection. We’ll perform a video scan of your chimney flue or furnace/boiler flue from bottom to top and document any damage or areas of concern we find. We’ll even show you the interior in real time so you can see exactly where damage is.

At the end of the inspection, you’ll be provided with a report, along with our recommendations, so you’ll know whether or not it’s time to invest in a new liner for your chimney or furnace/boiler flue. We’ll also email you a more detailed report (including photos) for your records.

We also reline furnace and boiler flues. Like your hearth’s chimney, your furnace/boiler’s chimney needs to be in peak condition for safety, performance, and efficiency reasons. Find out more about why these smoke pipes need to be replaced from time to time and why you shouldn’t just assume your furnace/boiler service company is keeping an eye on your flue right here.

For many years, chimneys were built without liners, which was incredibly unsafe. Afterwards, clay tile or terra cotta liners became the standard. But while these liners can last many years, they are prone to cracking as a result of thermal expansion, and they can also deteriorate and flake as a result of sulphuric acid, which is produced by moisture and creosote.

Metal liners soon began to take their place, but one thing that’s important to keep in mind is that not all metal liners are worth opening your wallet for. Aluminum and similar weaker metals are not approved for venting all fuel types, as they can’t safely and effectively contain the high heat and corrosive byproducts of combustion. The best liner, no matter the fuel type, is stainless steel. That’s why we reline with Olympia stainless steel liners, the chimney industry’s most trusted option.
