What Water Can Do To Your Chimney

Water is a major contributor to the ruining of your masonry chimney.  Your chimney is potentially one of the most taken-for-granted parts of your home.  You know it’s there, but rarely pay it very much attention.

It’s one of those things that you expect to be there for you when you need it but may not give it much additional thought in the meantime.  Not very many homeowners give much thought to keeping the chimney’s exterior in the best shape possible; “it’s all just cosmetic,” we think.  This thought process isn’t one to be ashamed of, but it is one to be corrected as soon as possible.

Water and metal are not the best of friends…

It’s common knowledge that water causes rust.  Water penetration can cause your metal damper assemblies and metal chimney liners to rust.  For every bit of rust you can see, there is likely to be even more that you can’t see.  Perhaps you haven’t seen any rust but haven’t been able to physically open your damper; it could be rusted because of water running down from the top (perhaps due to a missing or damaged chimney cap).  In order to prevent water from wreaking havoc on your metal chimney components, a chimney cap is an absolute must have!

Water can cause your brickwork to flake…

Chimney spalling (the flaking off of the brick surface) is a sign of severe moisture penetration.  Spalling bricks have cracks and breaks in the surface and often large, crater-shaped chips.  These bricks need to be repaired or replaced.  The best way to avoid brick spalling is to eliminate the moisture altogether.  If the area around your chimney crown is cracked or the cap itself is defective, this allows water to seep into the brickwork below, thereby increasing the chances for spalling.

Water has a tendency to erode your mortar…

Your chimney is exposed to the elements on the outside and the heat from your firebox on the inside.  As a result, the weathering process is increased.  As such, it is common for the mortar to begin to crumble and fall away, leaving open areas between the bricks, thereby exposing more surface area to these weathering agents.  Repointing your chimney might be your only option.  During this process, the damaged, old and loose mortar on your chimney is removed from the joints between the bricks and replaced with new mortar.

Unless you’re just itching for a reason to get rid of your chimney, there really is no excuse for not taking better care of it.  It’s time to have an experienced technician evaluate the condition of your chimney’s interior and exterior, get them repaired if necessary, and have your chimney coated with a waterproofing agent.  So whether you have a leaky chimney or are simply looking to be proactive and prevent leaks before they happen, call the professionals at Basic Chimney Sweep & Repair today!

Your Chimney and Water Damage

Depending on the type of material it is made from, your chimney may be more susceptible to damage by water than by fire. Certainly true for masonry chimneys, that is counter-intuitive, with no one really thinking about water damaging chimneys. Generally, the worry with chimneys in the minds of homeowners is all about sparks and fires.

Water: Love It or Leave It

Water, however, is often the original source of the explosive chimney fire of which responsible homeowners are rightfully worried. Allowed to seep in, it expands and contracts with the freezes and thaws of changing seasons. It does not sound that bad; it sounds almost poetic. However, it seriously threatens the integrity of chimneys.

That perfectly natural characteristic of water stretches and shrinks the material it is in, further deteriorating your chimney’s mortar. Water also, perfectly naturally, rots wood and erodes even rock, in a process that can probably be made to sound enchanting. Look around a canyon, however, to fully grasp what water can do to brick with the simple passage of time.

Let the River Flow Somewhere Else

It is not a pretty sight when it is your chimney that is crumbling, and a river in your fireplace is not exactly the interior decorating you had in mind. Leaks are usually a pretty clear sign that a roof-top canyon is developing, but hopefully homeowners do not let things go that far these days. Protecting chimneys from water damage is as easy as scheduling a certified sweep to get up there and see how they are doing.

It is a good idea, by the way, to do this in spring, when chimney sweeps are easier to schedule and before the rains come. If repairs or replacements are necessary, you have plenty of time to finish the job before a chimney in good condition becomes even more critical. Fire is definitely dangerous and mandates routine chimney inspections; but when it comes to chimneys, it is important not to play with water either.
