Chimney Liner Repair
When a chimney is traditionally constructed it is built using Vitreous Fire Clay flue liner (many incorrectly refer to this as terra cotta) Vitreous fire or clay tile is the most common chimney liner . These flue liners typically require frequent repair since they are prone to cracking. In addition, excessive creosote in the chimney can cause a fire that severely damages the clay tiles. Perhaps, you have noticed pieces of clay in the firebox, improper draft, smoke, or fumes in the house. Maybe your home inspector, chimney company, HVAC, or plumbing company mentioned a potential problem. These are all signs your chimney may need relining.
Why Your Chimney Needs a Liner
While most folks rarely notice the chimney liner, it is vital to your chimney and venting system. When you're relaxing by the warm glow of a fireplace or stove, the liner contains the heat inside the flue so that it doesn't spread and ignite nearby combustible building materials. It also helps improve heating efficiency to keep your home warm and cozy while making it easier for the smoke and harmful contaminants to vent out the chimney.
The sole purpose of your chimney liner is to contain the products of combustion and expel them out of the top of your chimney.
The flue liner deteriorates due to age, normal wear and tear, and heat. Moisture, excessive creosote, and corrosive gas residue can also accelerate its deterioration. Also, a small chimney fire that can cause clay tiles to burst. Deficiencies in the liner can present a profound safety concern that may go undetected until a chimney fire occurs. Many municipalities in the Washington DC Metro Area require a chimney liner to comply with building and fire safety codes.

Level 2 Chimney Inspection
The only way to know for sure whether your chimney needs to be relined is to have it inspected. Our chimney technician uses a specially equipped video camera to scan the entire interior of the flue. We’ll be able to see any cracking, imperfections, or other damages to the flue liner as we observe on a video screen in real-time.
Stainless Steel Liner
Stainless steel liners will improve heating efficiency, reduce energy costs, and are low maintenance.
Stainless steel chimney liners, either rigid or flexible, are used to repair or replace an existing chimney flue that has been compromised. It is commonly used inside a masonry chimney when the clay tiles have cracked or mortar joints have deteriorated. Stainless steel liners are also used in masonry chimneys that were built without flue tiles. Stainless Steel is the best material for the application so most liners come with a lifetime warranty.
