Our Stainless Steel ForeverFlex Liners Come With A Forever Warranty!

Finding out that you need to have your liner replaced can be disheartening — after all, it’s not exactly a “fun” expense. But there is a silver — er, stainless steel, rather — lining! Here at The Chimney Doctor, we install Forever Flex 316Ti stainless steel alloy chimney liners, which can resolve a whole host of issues and, when professionally installed, carry a forever warranty. These are UL tested and listed to the UL 1777 standard (Underwriters Laboratories), made of the highest quality metal available, and built to last!

What Makes Stainless Steel Liners Such A Great Relining Option?

While there are certainly other chimney liner options, like aluminum and clay tile, for example, stainless steel is a far better option for the following reasons:

  • Stainless steel liners are durable — Aluminum liners may last for several burn seasons, but as a weaker metal, they certainly aren’t a “forever” option. Likewise, clay tile liners can be incredibly durable, but when they do crack or undergo damage, it’s not always possible (or cost-effective) to make repairs. Stainless steel liners, on the other hand, are highly resistant to corrosion and can provide a lifetime of service. Plus, installation is quick, which means you can get back to enjoying your fireplace or stove faster.
  • Stainless steel liners are approved for use with all fuel types — If you have a wood-burning appliance and switch to gas (or vice versa) at some point in the future, your existing liner may not be equipped to vent the new appliance. Not all liner types can handle the combustion byproducts and heat of every fuel type, but stainless steel liners can safely vent all fuels –  wood, gas, and pellet.
  • Stainless steel liners come in a variety of sizes — The flue liner needs to be properly and proportionately sized to match with the attached appliance, and stainless steel liners make that easy because they come in a variety of sizes. Likewise, they are available in flexible and rigid models, which means that, even if your chimney is somewhat unique in its construction, we can find a stainless steel liner that will fit.
Chimney Relining

So when should you choose to reline with stainless steel?

Our experienced and knowledgeable, Chimney Safety Institute of America (CSIA)-certified chimney professionals will make recommendations and let you know whether or not stainless steel is the best option for your particular situation, but most commonly, we recommend stainless steel in these circumstances:

  • the clay tile liner is beyond repair (relining with stainless steel is typically the most cost-effective option in this situation)
  • you’re changing fuel types/appliance types or there’s a possibility you’ll change fuel types or appliance types in the near future (as long as your stainless steel liner is the proper size for your new appliance, you won’t have to invest in yet another liner when you swap appliances or fuels)

Of course, sometimes issues are a bit more extensive and require more than just the installation of a new liner. For example, when the chimney system is improperly constructed, doesn’t meet local building codes, or has other bigger safety and efficiency problems, it may be best to invest in the Ahren-Fire Fireplace Restoration system. This is an all-in-one system that is incredibly insulating and can bring a fireplace up to code, eradicate efficiency and performance issues, and make an otherwise unsafe and unpleasant fireside experience something wonderful.
