Chase Covers: What Is A Chimney Chase Cover and why do I need it

Chase Covers What Is A Chimney Chase Cover 

A proper Chase Cover is 26 gauge stainless steel or copper hood that covers the top of a chimney that contains one or more factory built, prefabricated fireplaces and their venting systems (chimneys). The Chase Cover should have a 4-inch down hang, closed and sealed corners, and incorporate a drip edge. The chimney pass-through should be extruded (pressed) into the main body of the Chase Cover. This eliminates leaking and allows room for expansion and contraction of the chimney as it heats and cools. In addition, a storm-collar and chimney cap are added at the time of the installation to insure proper water shedding.

Why Would A Chase Cover Need Replacing?

 Most chase covers installed at the time of original construction, were built of a very thin 30 gauge sheet metal, which was bent on the construction site, usually by hand. This resulted in a poor fitting cover that did not allow for expansion, contraction, or proper water shedding, causing excessive wear, rusting and leaking into the chase cover and ultimately the fireplace. What Makes Our Chase Covers The Best? Our Chase Covers are customized to fit your chimney’s exact specifications. We use highly trained stainless steel professionals to make our chase covers, specifically for the Chimney Department.

 Benefits of a Properly Sized Chase Cover By providing proper water shedding of the chimney, a properly sized Chase Cover prevents water damage and discoloration (rust stains) of the wood chase and preserves the integrity and safety of your prefabricated (metal) fireplace. It also enhances the appearance of your home.

Why Should I get My Chimney Cleaned

Why Should I get my Chimney Cleaned?

 The job of the chimney sweep is to remove soot, blockages and built-up creosote from your chimney liner, firebox, smoke chamber and damper. This cleaning will help create a safer operation of your system during the heating system. It take only a small accumulation of creosote glazing to create the potential for a chimney fire. Creosote is a highly flammable substance that builds up inside your chimney or liner as a result of burning wood. The rate of accumulation can be higher if you practice poor burning practices or have a burning appliance or stove that is not working well. Different types of wood create different amounts of creosote when burned. Pine causes a rapid build-up of creosote and should be avoided as a regular source of wood. Creosote can also reduce the draw of the fireplace and reduce efficiency.

Chimney Inspections should be scheduled once a year.

To be sure that all of your systems are in working order and operating as they should, it is recommended that homeowners get an annual chimney inspection. Most homeowners opt to have a Chimney Cleaning done every year as well, especially if they use their fireplace on a regular basis. Other venting systems connected to furnaces and stoves should also be cleaned on a regular basis to maintain safer operation. Fireplace, stove, furnace and heating appliance systems are important to your home and families safety and not an area to neglect or cut corners on. Don’t risk the chance that an undiscovered defect could turn into an expensive repair or worse yet – a chimney fire.
If you only have minimal use of your fireplace or stove, an inspection is still advised annually to look at all heating venting systems, chimneys, stove systems and furnace flues. During these inspections any defects or issues that may be found that require action even if cleaning is not needed.
When you have a regular chimney sweep company that you use, they will generally put you on an annual inspection schedule. During these inspections they will advise you if it is time to sweep.

When Do I Need A Chimney Inspection?

If you haven’t had your chimney inspected in a year or more, if you are having any performance issues with your chimney, fireplace or heating system or if you have recently purchased the home you should schedule an inspection. Don’t wait – waiting almost always results in additional repairs, and unfortunately sometimes in property loss. Every year in the US homeowners lose over 200 million dollars as a result of continuing to use unsafe systems.
Another important time to get your venting systems inspected is when you have upgraded or changed heating systems or added a stove or insert. An inspection will make sure that your chimney, lining and venting systems are adequate and in working order to handle the new changes.
If you have not used your fireplace in a long time, pests may have built nests that could clog your flue or chimney chamber. Winter freeze cycles and moisture combine to take an annual toll on masonry and liner materials too. Over several years the deterioration will eventually require attention. Normal wear and tear that is left unchecked will affect the performance of your system. The longer the defects go without being addressed, the more expensive the repairs are likely to be. Bottom line is – staying on top of your systems is not only the smartest and safest choice, it ends up being the most cost-effective too.

How Often Should I get my Chimney Cleaned?

This depends a lot on how much you use your fireplace or stove. The National Fire Protection Association says, “Chimneys, fireplaces, and vents shall be inspected at least once a year for soundness, freedom from deposits, and correct clearances. Cleaning, maintenance, and repairs shall be done if necessary.” So, even if you don’t use your chimney a whole lot – birds, squirrels, raccoons and other critters may have been using your chimney making it unsafe to use without clearing out the accumulated debris from nesting activity.
The CSIA (Chimney Safety Institute of America) says that fireplaces should be cleaned when 1/8″ of sooty buildup is evident inside the chimney and flue system. If any glaze is appearing in the flue, cleaning should be done even if there is less than 1/8″ of build up. Any time an appreciable accumulation of soot and creosote occurs it can be enough to fuel a chimney fire that may damage the chimney and even spread to the roof and home. Furnace flue systems also require cleaning, so don’t neglect regular cleaning of those venting systems.
Some heavy use fireplaces produce an incredible amount of soot and creosote during a cleaning. Recently we removed nearly 2 full 5 gallon buckets of material from one chimney! Removing this material is critical to continued safe use of the fireplace and reduced risk of chimney fires that start when this highly combustible material builds up to unsafe levels.

What is the Best Time to Clean my Chimney?

Ideally, before the start of the burning season during the summer or early fall is a great time to get your chimney inspection and / or chimney cleaning. Before you think about building a fire or starting up your furnace because the weather has changed, is the time to call your chimney sweep. Maybe you forgot the early cleaning before starting to use the fireplace, stove or furnace? Don’t wait until next year, we can do your chimney cleaning or inspection any time of year.

What is Chirping in My Chimney ?

    If you’ve heard some cheeping coming from your chimney, you probably have been a victim of a Chimney Swift nesting. And while the noises may have vanished with the coming of the cold, the remnants of these nestings and the future hosting job you inevitably have, still lingers behind. Chimney Swifts are protected under the Migratory Bird Treaty Act. This Federal Law prohibits the removal of any migrating bird without a federal permit. On top of that, due to the nature of migratory birds, if you had a nest in your chimney last year, you can expect the flock to return, to the exact same chimney. Therefore, if your goal is to keep the birds at bay, the problem must be taken care of in the proper manner at the proper time. On the other hand, you may wish to keep these little creatures around. In this article we will discuss how to keep Chimney Swifts away and also how to best handle providing a good home for these birds that is beneficial for you as well as for the Chimney Swifts.

 What Are Chimney Swifts   ?

   The most common migrating birds typically found in the Eastern United States are Chimney Swifts. These birds are unique little creatures. They are often mistaken as bats due to their rapid flight and their likelihood to reside in chimneys. But up close, these birds look very distinct. While they only weigh about an ounce and their body is only about 5 inches long, their wings span approximately 12 inches! Their wings have a unique shape to them, like thin half moons. In addition to their different wing design, unlike other birds, Chimney Swifts are not able to perch horizontally such as on tree branches and if they do end up landing on the ground or another flat surface, it is difficult for them to get into the air again. This difficulty with level ground is because their legs and feet are designed specially to hold onto the vertical walls of chimneys. In fact, they mostly live in the air and typically only land to sleep at night and raise their young. Rough vertical surfaces provide the resting places for these birds and a place to build their nests. Their nests are built onto the chimney walls using their sticky saliva and little sticks and twigs they gathered in flight. These birds live off of all types of insects which they catch while in flight. During the summer months they migrate to the North and when the weather turns chilly, the birds head to South America to avoid the cold.

 Why Should I Care ?

 The Chimney Swift population in Connecticut is rapidly declining at about 4 percent annually. Historically, these birds would nest in hollowed out trees and structures, but with the destruction of forests and decline of their natural habitat, these birds adapted and began nesting in masonry chimneys. This adaptation allowed the birds to survive in more diverse habitats but now with more and more chimneys being capped and metal flue liners installed, their expanded habitat is decreasing once again.

The chimney caps keep the birds from entering the stone structure in the first place and metal flue liners do not have enough rough surfaces for the birds to hang onto. In fact, uncapped metal chimney liners pose a threat for Chimney Swifts, as the birds can easily get trapped inside. Chimney Swift migration season starts in late March and then they are gone by the first signs of winter in early November. Therefore, once the Chimney Swifts have arrived and chosen your chimney to build their nest, you must leave them alone till they leave in the Fall. You may not even realize the birds are nesting until the young make noises when the parents bring home food. This is the only time the birds will create a ruckus and it always takes place about 2 weeks before they take flight on their journey to the south. But there is one major benefit to keeping Chimney Swifts around, the little birds eat about a third of their weight in insects every day. This includes troublesome mosquitoes, termites, beetles, and many other tiny pests. You can even consider the minor disturbances at the end of their stay as your only sacrifice for enjoying a bug free summer! Chimney Swift Towers Many bird lovers actually construct special towers designed to house the visiting Chimney Swifts as they migrate into the area looking for places to nest. You can find easy to build Chimney Swift Towers online and construct one near enough to your home that you can enjoy watching the birds, but far enough away that they will not create any problems. If your chimney is capped, they will look for the next best thing and find your tower. Some communities that are known as annual nesting grounds have constructed large towers for these migrating birds. The swifts favor larger chimneys, so abandoned factories with smokestacks are a favorite place for a summer home.

 How do I keep the birds away?

  If you act during the right time, preventing the nesting of Chimney Swifts is a very simple task. After finding Chimney Swifts nesting in your chimney, wait till they have migrated back to the south and have your chimney inspected and cleaned. Note that it is illegal for any chimney sweep to remove an active nest of migratory birds. If the chimney inspection reveals an active nest, reschedule the appointment to a date after the birds have moved on. It is important to have the nest and other remnants of the birds removed from the chimney once the Chimney Swifts have moved on to prevent fire hazards. Then, the best solution to prevent any further nesting is to put a chimney cap on the chimney. This will not only prevent the birds from nesting again, but it will also protect your chimney from leaves, rain water, other animals and numerous other things from getting into and creating problems with your chimney. Keeping the birds out is a simple fix and furthermore, a chimney cap is a good addition to any chimney anyway. Whether you appreciate the company or would rather steer clear of the commitment, it is important to know about the residents of your chimney.
