Prepare for Adverse Weather Conditions
If left unprotected from the adverse conditions around you, your Chimney will become susceptible to decline over time. Therefore it is important to address this issue before serious damage has the opportunity to set in. Water causes billions of dollars in damage each year in the form of staining, loss of insulation value, freeze/thaw damage, unnecessary decay, and leaks, that eventually culminate in structural failure.
Stay 5-minutes Ahead
Severe weather will always find your Chimney. A little time spent now protecting it will save you hundreds, maybe thousands of dollars down the road. Chimneys can take a beating from severe weather year-round. Water penetration is the single biggest cause of decay and damage. Waterproofing your chimney is a simple and easy task that will extend the life of your chimney for many years to come and protect it against expensive repairs. So simple, the Family handyman can do it.

Project Material List
Your Chimney is the most exposed part of the home. Over periods of time, the wind, rain, extreme heat, and freezing temperatures will cause costly damage to the chimney. To prevent further damage and avoid expensive reconstruction costs, use Chimney Rx products to repair, restore and protect this investment.

If the chimney has any mold, dirt, rust, creosote stains, efflorescence, or any other foreign matter, you will want to remove it first.

You won’t notice it on the light gray mortar joints, but try to keep it off the bricks as it can become more noticeable over time.
