What Does a Dirty Chimney Look Like?

Why You Need Fireplace Chimney Cleaning Even If You Don’t Use It

Chimneys need to be swept to remove residue that can block the flue and prevent proper drafting. This also removes flammable deposits which can cause a chimney fire. All types of appliances which burn fuel and vent to the outdoors should be inspected annually and cleaned when needed.

Plenty of homeowners assume they don’t have to clean their chimneys out if they don’t use them. Unfortunately, it doesn’t work out that way. If you don’t use your chimney, nature will. If you infrequently use your chimney, it can start to look like a great place for a nest to birds, squirrels, or raccoons. Their nesting debris, along with any sticks or leaves blown in, need to be removed to ensure that your chimney isn’t a fire hazard. Have a professional inspect and sweep your chimney to make sure it’s safe.

Have chimneys cleaned at least once a year, usually before cold weather sets in. Scheduling a fall cleaning will also clear out anything that might have fallen into the chimney during the summer.

Signs You Need A Fireplace Chimney Cleaning Even If You Haven’t Been Using Your Fireplace:

Strong Odors

If you had strong odors coming from your chimney the last time you used it, you probably have an issue with your chimney. Fires should produce a pleasant odor from the burning wood rather than from the soot that is stuck within your chimney. A drafting problem can easily cause smoke to gather in your home rather than going up through the chimney. Avoid smoke damage by paying attention to strong smells when burning a fire.

Creosote Build Up In Fireplaces

Creosote is a flammable substance that builds up in fireplaces and needs regular cleaning to prevent chimney fires. If the last time you had your chimney cleaned was before the previous burning season, then you have creosote in your chimney. Especially if you haven’t had the chimney cleaned since moving into a new place, you can’t know how much creosote is in there, waiting to light at the next fire. The only safe choice is to start a new fall/winter season with a clean chimney.

Hearing Animals Inside

Chimneys that are not in use are warm, dry places for animals and birds to call home. Chimneys are notorious for hiding birds nesting spots, and this can be a safety hazard. Nests can block the exit point of a chimney and cause smoke to back up into your home. Nests can also cause a fire on top of your home. If you hear animals or birds inside your wall or chimney you’ll need help clearing them out.

A Year Has Passed Since Your Last Fireplace Chimney Cleaning

As we noted above, you don’t know who’s been nesting in there, or what’s fallen or blown in from the outdoors. That alone creates enough risk to have a fireplace chimney cleaning before you start using your fireplace again.

Look for a chimney sweep credentialed by the National Chimney Sweep Guild or the Chimney Safety Institute of America, like The Irish Sweep.

Annual cleaning and inspections are very important to the safe and efficient operation of your home’s fireplace. The fireplace chimney cleaning process averages 45 minutes to one hour.

HAVE YOU HAD A CHIMNEY FIRE?

What many homeowners don’t know is that chimney fires can happen without anyone’s awareness. When you become aware that a chimney fire has been eating your home from inside the walls, it may not be the first time. This is part of why prevention is so important!

SOME SIGNS THAT THERE HAS ALREADY BEEN A CHIMNEY FIRE:

♦ ‘Puffy’ creosote, that’s cloud shaped and expanded beyond its normal form

♦ Creosote build up with rainbow colored streaks

♦ Any metal components that show warping (discoloring and distortion): the damper, metal smoke chamber, connector pipe or metal chimney, rain cap

♦ Flue tiles with large chunks missing, or that have cracks or evidence of collapse

♦ Flakes and pieces of creosote on the roof or ground nearby

♦ Burn marks on roofing material damaged by hot creosote

♦ Cracks in exterior masonry

♦ Evidence of smoke escaping through mortar joints of masonry or tile liners

If your home has already had a chimney fire, there is a reason it’s happened, and you’re in danger of it happening again until the cause is identified and addressed. Causes of chimney fires all have to do with structural safety and blockages or build-up in the chimney. The only way to be sure your fireplace is safe to use is to have regular chimney cleaning services.

HOW CAN CHIMNEY CLEANING SERVICES PREVENT THESE FIRES?

There are two main tasks chimney cleaning services can do for you: a chimney inspection and sweeping/cleaning your chimney. If you have concerns about fire safety, it’s best to do both. While inspection is important to identify evidence of previous fires and risk for future fires, it’s the cleaning that removes fuel for fires: creosote and debris.

Always be sure that you have working smoke alarms in appropriate places throughout your home, and that their batteries are fresh. With a little diligence and annual chimney cleaning services, you can minimize your risk for chimney fires.

MASONRY AND METAL CHIMNEYS: WHAT’S THE DIFFERENCE?

If you’re looking to replace or rebuild your chimney soon, you’ll have to decide whether you want masonry or metal chimneys. Not many people really know the difference between the two and can be quite confused as to which option to choose. While both are common options and can be used for a variety of different chimneys, there are some important differences that homeowners should be aware of to make an informed decision. Here are a few differences between masonry and metal chimneys:

WEIGHT

When it comes to weight, a masonry chimney is much heavier than metal.

Because of their weight, there may even be restrictions about where you can place a masonry chimney in your home. They’re generally used on the first floor of a building. Metal Chimneys can weigh much less and are better suited to multi-floor buildings.

ABILITY TO WORK AROUND OBSTRUCTION

Generally, metal chimneys are more flexible with complex buildings than masonry options. Depending on the layout of the home and where you want your fireplace, there may be an offset between the chimney and fireplace. This is when your chimney can’t go straight up because of an obstruction, and it’ll need to go around something. Masonry chimneys only function well with a small off-set, whereas metal chimneys can move around most things no problem.

HEAT REFLECTION PERFORMANCE

When it comes to providing high heat reflection, masonry chimneys really earn their keep. The higher the heat reflection there is in a fireplace, the better heat circulation you have in your home. You want increased heat circulation because it keeps the area around the fireplace warmer and strengthens the smoke removing updrafts of the chimney at the same time. Usually, metal chimneys don’t do as well here, so if that matters, go with a masonry chimney.

Taking these three considerations into account will help you decide on a masonry or metal chimney for your home!

WHEN SHOULD YOU REPLACE YOUR CHIMNEY?

When you think about home improvements, your chimney may not be something you think about. However, like many other things in you home, it can break down and need replacement. But how do you know when you should replace your chimney since it’s usually not something on your repair list? Well, it all depends on the condition of your chimney.

Chimneys are very sturdy, but they still need some TLC every now and then to functional properly. And if your chimney is in really bad shape, it might be time for a chimney replacement. To see if your chimney needs fixing or replacement, it’s recommended that you do an annual check, usually in a

season that you won’t be using your fireplace. You’ll also want to check it out after any severe weather like hail storms or hurricanes.

We’ve rounded up a few obvious signs to check for yourself, right after you schedule a professional chimney inspection.

1. A DAMAGED CHIMNEY CROWN

The crown of your chimney is a vital piece of masonry as it protects the chimney from anything that might fall into it (expect for directly above the flue). It keeps out water and weather damage and takes a beating. If it’s injured, the damage can spread down the chimney, resulting in a complete rebuild. It can also degrade and crack due to age, which can be a disaster for the chimney.

2. WHITE SALTS ON BRICKS

White bricks can mean water damage inside the bricks, which pulls out the natural salts and minerals to the surface of the bricks. The white staining can wash off easily, but if comes back, you’ll definitely need to call a professional to come in and help.

3. SPALLING OR SHALING

Spalling is the result of water entering brick, concrete, or natural stone. It forces the surface to peel, pop out, or flake off. Spalling can eventually cause crumbling and destruction of a structure. If you have spalling bricks, it means your chimney is damaged and will need to be rebuilt. You’ll want to call a professional ASAP.

Shaling is also caused by water, but describes what happens to affected tiles. If you notice that tiles or pieces of tiles fall into your fireplace, this is shaling. You’ll definitely need a chimney replacement if you see this!

4. NO CHIMNEY CAP

The chimney cap is like a little hat worn by the flue, to keep debris and water out. Some chimneys don’t have a cap and the ones that do can lose them from time to time. If your chimney doesn’t have one, it’s because it’s most likely sustained some damage at one point. The cap acts as the first line of defense and you’ll want to call a professional for an inspection before any damage gets worse, needing a full chimney replacement.

ROUTINE HOME FIREPLACE & CHIMNEY CARE

Do you know how to care for your chimney? If you’re wondering what I mean by that, you probably don’t. Which is why you need to learn basic chimney care! As your go-to heating option in the colder months, you’ll want to make sure it’s ready to warm up your home when the weather starts to get chilly. The truth is, not many people think about their chimney much, which is why problems arise when they want to use it. To avoid these problems, here are some basic tips on home chimney care:

1. ALWAYS LEAVE SOME ASH

Although you’ll want to clean the firebox monthly when it’s in use, a clean firebox retains about an inch of ash. This allows your fires to stay strong and retain heat easier.

2. HIRE A CHIMNEY SWEEP

For safety, you’ll want to call a chimney sweep to not only clean it, but also provide an inspection of the fireplace and chimney. They’ll look for any damage or evidence of creosote, which is a tar-like buildup. Do this at least once a year before you begin using the fireplace again.

3. CLEAR THE AREA

As part of basic fire safety, you’ll want to keep the fireplace area clear for the entire fire burning season. Not just while a fire is burning. Any furniture should be at least 36” away from the fireplace to avoid any sparks igniting it, which can be a fire hazard. No flammable decor or plants near the fire.

4. ENSURE THERE’S A CHIMNEY CAP

You’ll want to make sure that your chimney has a cap to prevent any birds from building nests inside or any animals from climbing it. Most importantly, it keeps the flue and fireplace dry, which prevents the breakdown of the materials your chimney is made of.

5. MAKE SURE THAT THE DAMPER IS CLOSED

The damper is the hinged flap that’s above the fireplace and it controls how much air passes through the chimney. You’ll want to leave it open when a fire is on, but close it when it’s out to prevent any heat loss inside your home.

Avoid Chimney Repair With Removal

When a home has a chimney, and something is awry with it, many homeowners only consider 2 options: fixing it or leaving it in place but declaring the fireplace unusable.

But there are two unexamined options: removing the chimney completely and replacing it with a safer style of chimney.

WHY REPLACE YOUR CHIMNEY?

No amount of repair will make a masonry chimney as safe as a metal one. Masonry chimneys are more likely to fall down and hurt or kill someone during an earthquake than any other part of the house. A full replacement means leaving that risk behind, and still enjoying your fireplace as you always have. It’s all gain, no loss.

WHY REMOVE YOUR CHIMNEY?

Chimney removal is another great option. Why do I call it “great”? Because no chimney means no risk of chimney fires, no risk of a falling chimney, no more place for rain to enter your home, or your hot air to escape in winter.

When having a chimney removed you can opt to remove it below the roof line (if it’s not along on exterior wall), and keep your mantel and firebox area indoors (decorative only). Or you can remove the entire fireplace system. This can create new space in your home, too. The chimney removal cost is often less than repair, and unlike repairs, you’re not going to have to do it again in a few years. No more chimney maintenance for you!

Sometimes a chimney is utilized to vent gas appliances that are connected to the metal flue liner. If your chimney is being used to vent gas appliances such as a furnace, water heater, or boiler, a vent will still need to penetrate the roof to carry the exhaust gases to the exterior after your chimney is gone. This doesn’t mean you can’t remove your chimney. Your chimney removal specialist can help you navigate this safely.
