Why Ivy is Damaging Your Chimney

Climbing vines such as ivy or wisteria have been used for years as a way to cover up unsightly exteriors or add a touch of whimsy to a home. While these vines may add curb appeal, they can also cause serious damage to your home’s exterior, especially if they are growing on or around your masonry chimney.

Why Is Ivy Bad for Chimney?

Many homeowners believe that ivy is no different from any plant growing in the garden. Unfortunately, while it can be a charming addition to the exterior of a home, it is can also cause significant damage. Below are three of the most common ways that ivy and climbing vines are bad for chimneys.

1. Ivy causes cracks

Climbing vines such as ivy do not grow vertically on their own; they need a structure to hold onto in order to climb. When this happens on your chimney, the roots and tendrils of the ivy snake their way into the bricks and mortar in order to continue climbing. This can create cracks and holes in the masonry; at the plant continues to grow, so too does the size of the damage.

Even chimney chases covered by siding or shingles can be affected. Just like with masonry, ivy on a chimney chase can also cause cracks and holes to form. Likewise, on these building materials tendrils from climbing vines can cause staining and discoloration that is difficult to remove without damaging the siding itself.

2. Ivy traps moisture

Ivy’s lush, green foliage can create a cover of shade that is difficult for the sun to penetrate. Because of this, water from rain, snow, morning dew, and even sprinklers can become trapped against the masonry. Over time, the combination of water and the holes and cracks created by the ivy’s roots can cause significant cracking and spalling.

In addition to damaging the masonry, trapped moisture can also encourage the growth of mold or mildew. Exterior mold and mildew growth can cause odor both inside and outside your home, as well as affecting your home’s air quality. This can be particularly harmful to those with breathing condition such as asthma or allergies.

3. Ivy invites insects

The same leafy coverage that prevents water from evaporating also provides the perfect home for all kinds of insects. Protection from predators and an abundant food source are just two of the reasons why climbing vines such as ivy can easily become host to insect infestations. Termites in particular have been known to take up residence in ivy; the network of branches, roots, and leaves often give these insects direct access to wood siding or trim around your home.

While ivy might add character or curb appeal to your home, it can also cause significant damage to the exterior. Chimneys, whether they are made of masonry or covered with a chimney chase, are particular susceptible to damage from climbing vines. If your home has ivy growing on the chimney structure, contact Lords Chimney today to learn more about removing the ivy and repairing the damage it may have caused.

Spotting Masonry Damage In Need Of Repairs

Your chimney does more than just decorate your roofline; it protects your entire fireplace system and helps keep you and your family safe. While chimneys are built to last and to withstand the elements, they can deteriorate due to damage, poor construction, or age.

In order to keep your chimney working well and in good condition it is important to be able to spot the signs of masonry damage. By knowing when your chimney is damaged, you can quickly enlist the help of a chimney professional to get it repaired and back in good working condition.

How masonry gets damaged

Masonry is one of the strongest building materials available, which is what allows well-built fireplaces and chimneys to stand the test of time. However, even the most well maintained masonry structures need repairs over time. Below are some of the most common causes of masonry damage, as well as what repairs can fix them.

Water: Water and moisture from rain, ice, and snow can be some of the most damaging forces that affect your chimney. Because bricks are naturally porous, they may absorb small amounts of water. As the water absorbed by the bricks freezes, it expands and creates progressively larger and larger cracks and holes. This freeze-thaw can cause significant damage to the masonry in as little as one year, causing bricks to crack, chip, and spall.

In addition to affecting the bricks and mortar of the chimney, water can affect many other parts of your chimney system. The chimney cap and crown are also particularly susceptible to water damage due to their location; many chimney leaks are caused by damaged chimney caps and crowns. Chimney leaks can lead to damage to the flue and firebox, as well as damage to the walls and ceilings surrounding your chimney.

One of the best ways to prevent water damage is by having your masonry waterproofed. The waterproofing process involves coating bricks and mortar with a specially designed chimney sealant. Made for porous bricks, it keeps water out while still allowing gasses to pass through. Waterproofing products can also be applied to chimneys with existing water damage to slow or stop the deterioration process.

Settling: Over time, all homes are prone to settling. Settling can affect many different parts of your home, including your fireplace and chimney. Masonry fireplaces that are not built on proper bases may become damaged due to settling; this often shows up as cracks in the firebox or chimney.

Chimney or fireplace cracks caused by settling can be repaired using the detailed tuckpointing process. Tuckpointing involves the removal of the existing damaged mortar, replacing it with new mortar that matches the color and consistency of the original. This strengthens the masonry and prevents further damage.

Subpar materials: Sometimes, chimney damage can be caused by the wrong materials. If subpar materials were used in the construction of your fireplace or chimney, it may be more prone to damage. Likewise, mistakes made during installation can also affect your fireplace system. This is often seen in fireplaces or chimneys that are built by general contractors rather than skilled masons.

No matter what is causing your masonry damage, it is important to have it repaired as soon as possible. Contact Lords Chimney today to schedule your masonry repair appointment!

Chimney Swifts

Spring has officially arrived, and with the warmer temperatures and longer days come new babies for many different kinds of animals. Unfortunately, many birds and small mammals may view your chimney as the perfect place to build a nest and raise their young. While many animals and their nests can be safely and humanely removed if they get into your chimney, one cannot: the chimney swift.

About chimney swifts

A chimney swift can be recognized by their size, color, movements, and sounds. Chimney swifts are small birds with narrow bodies and long wings. While up close they are a brown-gray color, they may appear black when backlit against the sky. Swifts fly and twist side to side erratically, and have a distinct high pitched chirp.

Although chimney swifts spend their winters in South America, they migrate north to the eastern United States and Canada each spring to nest and raise their young. According to the Cornell Lab of Ornithology, “Their ability to travel over long distances and through a variety of habitats exposes them to a wide range of microorganisms.”

Chimney swifts got their name because of their unique ability to build nests that stick to the side of slippery flue tiles. While swifts traditionally prefer to nest in hollow or dead trees, the increase in size of cities, suburbs, and agricultural areas has forced them to adapt.

Removing chimney swifts

If birds take up residence in your chimney, your first reaction may be to have them removed as soon as possible. Unfortunately for many homeowners, chimney swifts and several other species of migratory bird are protected under the Federal Migratory Birth Treaty Act. This law makes it illegal for anyone to remove or destroy chimney swift nests, eggs, or hatchlings, with severe fines and penalties for anyone who violates the law.

Luckily for those dealing with an unexpected nest of chimney swifts, the birds have a relatively short nesting period. Chimney swifts can lay, hatch, and raise their young in about six weeks. Likewise, as they nest in the spring and summer when fireplaces are not typically in use, the presence of a chimney swift nest of often little more than a minor inconvenience.

Keeping chimney swifts out

Because chimney swifts cannot be removed once they have taken up residence in your chimney, the best thing homeowners can do to prevent them is to have their chimney regularly inspected. A chimney inspection can ensure that there are no areas for chimney swifts to enter through, such as a damaged chimney cap.

Likewise, because chimney swifts are migratory they tend to return to the same nesting ground each year. Because of this, if you have chimney swifts find their way into your chimney it is extremely important to have the chimney inspected and repaired after they leave. If not, you may find that your chimney becomes an annual summer home for a family of chimney swifts.

If you think you have birds in your chimney, contact Lord’s Chimney today. Our expert technicians will be able to find out if they can be removed as well as help prevent them from getting in again.

Damper Stops

Gas fireplaces make a beautiful addition to any home and are an increasingly sought after feature for homebuyers. Valued for their beauty, functionality, and ease of use, more and more homeowners are converting their existing open hearth fireplaces to gas. However, what many may not realize is that their new gas fireplace is missing a required component – the damper stop.

Although many homeowners may not know what a damper stop is, they are a necessary part of a gas fireplace. Unfortunately, many homes with gas fireplaces – especially those that were not professionally installed – may be missing this important piece.

damper-stop-image-houston-tx-lords-chimney

What is a damper stop?

A damper stop is a piece of metal designed to ensure that the flue of a gas fireplace always remains partially open. With a traditional hearth fireplace, the damper  is opened or closed when the fireplace is in use.

While gas fireplaces also need the flue to be open while in use, there is often no mechanism to close it; instead, the damper is simply left partially or fully open when the gas insert is installed. However, leaving the damper open at installation does not ensure that the damper will stay open forever. Strong winds, house settling, or other damage to the flue or damper can cause the damper to close.

Because of this, damper stops were designed to be installed as a way to keep the damper permanently open. Although they are required, some homes with gas fireplaces – especially those that were self-installed by previous homeowners or untrained installers – may not have them.

Dangers of a missing damper stop

A damper stop may seem like an insignificant piece of the gas fireplace. However, it is a specially designed safety precaution that can help protect your family, namely against carbon monoxide poisoning.

Carbon monoxide is an odorless, tasteless, colorless gas that is often called the “silent killer” because it is so difficult to detect. When the damper is open, carbon monoxide is able to safely travel up the chimney and out of your home. However, if the damper is closed this deadly gas can back up into your room, affecting the health and safety of you, your family, and your friends.

How to identify a damper stop

With a traditional hearth fireplace, it is easy to tell if the damper is open or closed; if smoke back flows into a room when the fireplace is in use, the damper is closed. Gas fireplaces, however, do not produce smoke, making it much more difficult to tell if the damper is open or closed.

Missing damper stops are most frequently identified during home inspections; however, they can be easily missed, leading homeowners to believe that there is nothing wrong with their gas insert or fireplace.

To make sure that your gas fireplace has a damper stop that is correctly installed, contact Lord’s Chimney to schedule a chimney inspection. Our trained chimney sweeps will be able to inspect your chimney and fireplace to determine whether or not your gas fireplace has a damper stop; if it is missing, one can be installed. To make sure your chimney is up to current safety standards, contact us today!

Chimney Cleaning Logs

If you walk down the aisles of your neighborhood big box home improvement store, you are bound to see a wide variety of products designed to help homeowners clean and maintain their fireplaces. While some of these products can be useful, they should not be used to replace regular annual chimney maintenance by a certified chimney sweep.

One such product that our customers regularly ask about are “chimney cleaning logs”. Sold for less than $20 at many home improvement stores, chimney sweeping logs advertise their ability to significantly reduce creosote buildup in the chimney. Because of this, some homeowners purchase and burn these products as their only form of chimney maintenance, patting themselves on the back for saving money on a chimney sweep.

chimney-logs-get-the-facts-houston-tx-lords-chimney

Despite their advertising claims, these logs are no replacement for a professional chimney cleaning. Although they may be able to remove some creosote buildup, there are a number of ways that they are deficient at maintaining the health and safety of your fireplace system.

Why loosening creosote is just part of the job

The primary purpose of a chimney cleaning log is the removal of creosote; the smoke from the log loosens the creosote and causes it to fall down the flue and into the firebox, where it can be safely swept up and removed.

In theory, this is an excellent system. Unfortunately, the reality leaves much to be desired.

Most flues are not a straight vertical line between your firebox and the top of the chimney. Depending on your fireplace’s location, your flue may have one of more curves and bends in it. When this happens, the loosening of creosote by the chimney cleaning log merely causes it to fall and accumulate in the bends of the flue. This may not only block the flue, but can also create a significant fire hazard. Even fireplaces without curved flues may wind up with the majority of the creosote trapped on the smoke shelf, which can be difficult to access and clean without proper training.

A chimney cleaning log is no substitute for a chimney sweep

While a chimney cleaning log may be useful in loosening creosote, it is no substitute for the services performed by a certified chimney sweep.

“I usually tell people using one of those logs instead of having your chimney cleaned manually is like chewing Dentyne instead of brushing your teeth,” said Allan Bopp of Bald Eagle Enterprises. “It may help a little, but it’s a poor substitute for the real thing.”

Likewise, a chimney cleaning log has no way to know or tell you if your chimney is damaged in any way. There are a number of hidden issues such as cracked flue liners, decaying masonry, or damaged chimney caps or crowns that can only be spotted by a sweep during a chimney inspection. Because many of these chimney issues do not affect performance, you may have no idea there is even an existing issue.

Don’t trust the health of your chimney or the safety of your family to a $20 log bought at a big box store. Instead, have an annual chimney sweeping and rest assured that you can safely use your fireplace for the rest of the year. Contact Lord’s Chimney today to schedule an appointment!
