Here at Old Hat Chimney Service, we make sure to help out as much as we can – one chimney problem at a time. In our many years in the chimney industry, we have encountered more chimney problems than you can even imagine. One of the most common chimney problems that we’ve encountered is chimney mold.

Molds are basically a type of fungi that form really tiny spores. Their spores cannot be seen by the naked eye; therefore we have no way of detecting whether there is a horde of molds growing in our chimneys at this very moment. Molds are characteristically annoying and difficult to get rid of because they have the ability to survive even in the harshest environments. There are several types of molds and mold growth which can be characterized by their color and the presence (or absence) of a musty odor.

How do they get in our chimneys?

Mold growth is commonly associated with food and dubbed as one of the most obvious signs of food spoilage. Because of this, some of you may be wondering what these molds are doing in your chimney. But the thing is, mold growth isn’t only limited in food. Anywhere or anything with moisture coupled with the right kind of environmental condition is optimal for mold growth: Food, our chimneys, the basement and our shower stalls – these are all ideal breeding grounds for molds.

What are the signs that indicate mold growth in our chimney?

The most common tell-tale sign of mold infestation in our chimney is the odor. You need to look out for that distinct foul, musky smell. If you do, then it’s time to get your chimney checked by a professional.

How can you remedy chimney mold?

All you need to remember is this: chimney leaks = mold growth, mold growth = chimney leaks. In the industry, every chimney professional certified by the Chimney Safety Institute of America already knows that chimney leaks and mold growth are an inseparable tandem.  Once you discover that there are molds in your chimney, it would only mean that there is a leak in there somewhere. Find the source of the leak and have it fixed.

Common Masonry Repairs

If you've noticed crumbling, cracks or gaps on your chimney masonry, have it repaired right away... before it develops into an even greater and more costly problem.

If you’ve noticed crumbling, cracks or gaps on your chimney masonry, have it repaired right away… before it develops into an even greater and more costly problem.

Most homeowners never think about masonry chimney maintenance beyond the usual annual flue cleaning. Unfortunately, ignoring your chimney can cost you big! Problems that are addressed early on can prevent bigger issues down the road; small repairs are far less costly than larger ones. The certified pros at Old Hat Chimney Service are here to handle all of your masonry repair needs.

Is Crumbling Mortar a Problem for You?

Your chimney is exposed to the elements on the outside and the heat from your firebox on the inside. As a result of this two-front attack, the weathering process is sped up. As such, it isn’t atypical for your mortar to begin to crumble and/or break away. This leaves open areas between the bricks, which exposes even more surface area to these weathering agents and processes. Repointing your chimney might be recommended. 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.

Has your Chimney’s Crown Seen Its Better Days?

Your chimney crown is a reinforced concrete cap placed over the top of your brick and mortar chimney. A properly constructed crown sheds water and serves as a protective covering for your chimney against harsh weather. Your chimney crown is exposed to the same elements that wreak havoc on your chimney itself. As such, it can eventually crack or break and need to be replaced. The replacement will either be cast-in-place (a form is placed on the top of your chimney and filled with cement to the exact specifications required by your particular chimney) or precast (a prefabricated unit that is placed atop your chimney).

Are the Bricks in Your Chimney Cracking or Spalling?

When chimneys spall, it’s a sign of severe moisture penetration. Spalling—the flaking off of a brick surface—is evident when the face of the masonry is missing. Pieces of bricks may be found on the ground or on your roof. Damage can be increased if your crown isn’t poured with an overhang/drip edge, as water that is diverted is allowed to flow straight down the face of your chimney. Spalled bricks can’t be repaired and must be replaced.

Dealing with masonry repairs can be frustrating. Your chimney and fireplace play a large role in your home; when issues arise, we know you want them taken care of correctly, quickly and affordably. Our expert technicians are dedicated to making your system look and feel like new again. If your system is in need of repair, or you need a chimney inspection to determine the cause of a problem, call us today. We are ready to help!

Repairing a Leaky Chimney

Water in your chimney is a recipe for disaster. Have CSIA-certified experts waterproof your chimney as well as repair water damage, if there are any.

Water in your chimney is a recipe for disaster. Have CSIA-certified experts waterproof your chimney as well as repair water damage, if there are any.

According to the Chimney Safety Institute of America (CSIA), water is the biggest enemy of your masonry chimney. When your chimney brickwork is penetrated by water, all sorts of expensive damage is possible, and when leaks develop, it is definitely time to have the leaks repaired by a CSIA-certified company like Old Hat Chimney Service. With experienced technicians thoroughly inspecting your chimney for the leak source, our staff can zero in on the problem, fix your leak, and even safeguard your chimney from future leaks, saving you money in more repairs. We would like to tell you more about our common chimney leak repairs and prevention methods.

● flashing

The seal between the roof and your chimney, flashing plays an important role in keeping water out of your chimney. The CSIA describes flashing as preventing rainwater from running down your chimney, entering your home’s interior, damaging your ceilings and walls, and even rotting your rafters. At Old Hat Chimney Service, we realize the importance of customized flashing, and we do all of our flashing in layers to be more effective. We can even design a custom cricket, a raised ridge built against the problem chimney wall, to encourage water to flow into your gutters, away from your chimney.

● chimney crown

Located at the top of your flue, your chimney crown also protects your chimney from water penetration. However, your chimney crown can suffer cracks and other damage, and water can get in through these cracks. Chimney leaks are a sign of chimney crown damage, as are white stains or green growth around the top of your masonry chimney. The CSIA recommends a chimney crown be constructed of a Portland cement-based mixture and formed to provide an overhang projecting beyond all sides of the chimney by a minimum of two inches, and our Old Hat Chimney Service CSIA-certified technicians will do that as well as repair cracks.

● chimney cap

Even more important in the battle against water penetration, a chimney cap sits on the top of your chimney and keeps out water, debris, and animals. A properly fitted and installed chimney cap should last for years. According to the CSIA, a chimney cap is the most inexpensive preventive measure against water penetration and chimney damage. At Old Hat Chimney Service, we sell a wide variety of styles and sizes in different types of metals, and our professional installers will customize your chimney cap to perfectly fit the top of your chimney.

● masonry joints

If your exterior masonry joints have deteriorated, water can leak through those cracks. Old Hat Chimney Service provides the best way to repair these damaged joints: tuckpointing. Extensively trained in this process, our specialists have vast experience in tuckpointing and can restore historical chimneys as well as repair damage by removing the old mortar and and replacing the joint with new mortar.
