Newsletter September 2009


September is the time of the year when most of us fire up our chimneys or heating appliances for the first time in the season.

Now is the ideal time to make sure that your chimney is in proper working condition, before the cold season is in full swing.

Installing a chimney liner is one of the best decisions that I have ever made, in order to keep my chimney efficient and my family safe. I was so impressed with the results, that I decided to go into the business.

From my family to yours,

Fire Safety Tip - How Safe Is Your Chimney?

Your chimney has a big responsibility. It carries toxic gas out of your home, and while doing its job, it must withstand constant attack by acid, creosote, and extreme temperatures for months on end.

These conditions cause chimney damage and deterioration, and when that happens, your family's safety is in question. The risks of carbon monoxide poisoning and house fire become real.

Also, older chimneys were not designed to vent modern heating appliances. Besides, no chimney lasts forever.

You Need A Chimney Liner When You Notice Any of the Following:

1- Staining From Leaking Condensation: The condensation in your chimney is seeping through to the interior of your home, or your chimney exterior, and creating costly damage.

2- Disintegrating Chimney Structure: Acidic moisture goes through freeze and thaw periods with expansion and contraction, creating cracks in your mortar and flue tiles.

3- Poor Draft: You have an improper flue size matched to your heating appliance.

4- Tight Clearance: You have inadequate clearance to the wood framing of your home.

5- Damaged Chimney Structure: Will allow carbon monoxide, smoke, and fire to enter your home.

6- Down-Drafting and Smoke: If you have an improperly lined flue, you can expect an unsteady draft, leading to a downward flow, bringing smoke into your home.


Rock-Flex Chimney liner is the ultimate solution to the problems that plague most chimneys. State-of-the-art Stainless Steel walls provide an airtight and watertight barrier that seals in gases and creosote.

The Rock-Flex liner is made of 100% 316Ti Stainless Steel. High quality Stainless Steel, combined with Titanium, creates an alloy to withstand the acidic moisture and extreme temperature fluctuations inside your chimney. Rock-Flex will even contain a chimney fire!

Actually, Underwriters Laboratories (UL) tested Rock-Flex, and has awarded its seal of approval. UL has declared that the Rock-Flex system excels standards for chimney safety, and can even withstand a 2100 degree F chimney fire, and still maintain its structural integrity.

Rock-Flex also carries a LIFETIME warranty, the first warranty in the business that is transferable to the next homeowner. No fine prints in this warranty, just peace of mind.


If you have any questions regarding the type and size of the Rock-Flex liner that you need, we would love to talk with you. We are available 7 days a week.
