Chimney Relining: Repairs, Installation, Resizing & More

Your historic home may have a chimney system that hasn’t had a liner installed – an inefficient and highly unsafe situation. Pristine Sweeps’ technicians are called to install new lining systems for a variety of reasons:

  • Your existing clay tile liner might have joint damage or cracks, or it may be improperly sized for the appliance it’s venting.
  • Or you may be adding a whole new fireplace and chimney system to your home.

Our recommendations will always depend on your individual system and your individual needs, but stainless steel liners are a great choice for just about any application.

Stainless Steel Chimney Liners: A Good Choice for All Fuels

While terra cotta clay tile liners are effective in chimneys that are venting a wood-burning appliance, tile liners aren’t as effective when it comes to gas appliances. Stainless steel liners, on the other hand, perform well, venting any kind of fuel, from wood to gas, coal or oil. Which makes relining with an M-Flex Lining System ideal if you’re converting an existing wood-burning appliance to burn gas by having gas logs installed – something that’s becoming more and more common as busy homeowners look for ways to enjoy their heating appliance more conveniently.

The byproducts of the combustion in your fireplace or stove, by and large, aren’t friendly – high heat can stress and crack clay tile liners and their joints, acidic deposits will wear on masonry and clay tiles alike, and creosote can, in its worst state, develop into a thick, candy-like coating that’s difficult to remove and often results in liner damage. M-Flex stainless steel liners, however, are specially designed to resist all those damaging effects, so you can expect strong, long-term performance. These products carry a lifetime warranty, too, which brings some worthwhile peace of mind along with it.
