Why Certified Chimney?

We have been in the industry for over 25 years. 

Whether you need cleaning, maintenance, chimney lining services, or a major repair, we can help. Your commercial chimney differs significantly from a residential chimney, so you need experts in the commercial industry. Look no further than Certified Chimney, our Long Island chimney service. We will take the time to get to know your building and make the necessary improvements. We work WITH your company to keep you up to safety code and regulations.


We begin running innovative, in-depth tests to ensure the safety of your system: 

Video ScansCommercial Chimney Service, Repair, and Inspection on Long Island and New York City

Our video scanner allows us to attain a detailed view of the chimney cavity. 

This gives a much more thorough scan than a regular level 1 chimney inspection. We use state-of-the-art video cameras and scanning tools that are designed to operate in small 3” venting pipes up to 13” x 18” fireplace flues. For larger jobs, we can add on stabilizers and utilize rotating cameras to gain a comprehensive scan of any size chimney. 

Smoke Tests

Even more conclusive than a video scan is a smoke test. 

The smoke test analyzes the tightness and condition of your chimney. A smoke test is performed by closing off the top and bottom of the chimney and filling the chimney with smoke. Smoke will escape through any gaps or joint openings, revealing any structural flaws in the chimney. The purpose of the test is to determine if the chimney is seeping any fumes during regular operation. 


Once we determine the efficiency and safety of your chimney, we may recommend the following products: 

Commercial Chimney Liners

We may recommend using stainless steel or composite flexible lining systems that can conform to any shape, size, or length. 

They are corrosion-proof and airtight. The flexible liner is very easy to run through a chimney and can be a great solution for chimneys that are not entirely straight or have structural issues. 


Oil to Gas Conversions

Converting from oil to gas can result in significant cost savings over the long term and is better for the environment than oil. 

Frequently, when switching from an oil chimney to a gas chimney, an inspection and sweep are required. The existing flue liner may or may not be acceptable for a gas appliance. Gas emits a different type of exhaust than oil and therefore requires a different liner. Over time, fumes can erode the liner and begin to leak fumes. Our professional technicians will be able to access your current chimney and recommend the best products for your personal needs. Together, we will decide the safest and most sustainable liner. 


Custom Chase Cover Replacement

A chimney case cover is located on the top of the chimney. It is a metal cover that deflects water and protects the bricks of the chimney. Chase covers can be made of a variety of materials, but the most common is stainless steel.
