Chimney Swifts in Your Chimney

Chimney swifts in chimneys are a common problem because the migratory path of the birds is so far ranging. It extends from Canada across the entire eastern half of the United States at points, changing as they fly north and south every spring and fall. They LOVE chimneys, which is how they got their name and why they are such a common problem.

Unfriendly Skies

That leads to what you can do about it if you live along their chimney-hopping routes. The first thing is to be concerned about their migratory path regardless of the frequency with which you see them fly in your skies. They are difficult to distinguish from other ‘long narrow cylindrical bodies’ up there, and we never see everything that happens above our heads.

If you are not sure whether or not their migration involves your neighborhood, it is important to find out. You can contact either fire safety professionals or certified chimney sweeps in your area…both will know. If you know you are in their line of fire, so to speak, it is equally important not to discount their presence just because you have never seen one.

Restrictions for Frequent Flyers

To repeat, chimney swifts LOVE chimneys.  If yours is unprotected, there is a 50-50 chance they will check it out, at some point during their migration. If your home is within their migratory path, you need a chimney cap or a bird screen, and it needs to be strong. If not, you risk the swifts choosing your home as their next vacation spot.

If they are already in your chimney, their removal is restricted by law and must be performed by someone with a Federal permit to do so. The legal protections for chimney swifts cover their nests as well, so even if the bird is gone, you cannot simply remove the nest and debris it left behind. Again, certified chimney sweeps in your area will have those permits and are also both trained and experienced in their removal.

Protecting Your Home from Creosote Build-Up

At this time of year, when fireplace use is finally slowing and coming to a halt, creosote buildup raises two issues. First, whatever creosote is inside your flue, contact with moisture is going to make the fumes it produces much worse. Secondly, simply shutting those smells out of your house by closing the damper does not solve the greater issue.

Build-Up Stinks

Generally speaking, when you can smell something inside your house, it is time to really do something about it! For many of us, the solution is to throw the smelly item away or clean up the mess. However, a smelly chimney is just a bit more involved.

Many of us like to be able to use the chimney as the vent it is. That means a damper left open and a cap on top which naturally improves the chimney’s draft and keeps water out. Neither one is safely possible with creosote buildup greater than ¼” of SOOT or 1/8^” of later stage creosote.

…And It’s Bad For Your Chimney’s ‘Skin’

Every chimney cap will do a lot to keep wind gusts that cause downdrafts out of your chimney. It makes no sense at all, however, to cap a flue that contains unacceptable amounts of creosote. The longer that creosote stays in your flue, the more damage it does, which is the second type of harm you need to prevent.

Not only does creosote emit toxic fumes, unnecessarily exposing you to harmful carbon monoxide, but it is corrosive. Furthermore, the greater its accumulation, the more difficult it is to remove and the more dangerous it becomes. Protecting your home from creosote build-up means not allowing it to accumulate to any significant amount. When buildup is noticed, it is time to call a CSIA certified chimney sweep to take care of this problem.

What Is the Best Season for Your Annual Chimney Inspection?

The language used in authoritative recommendations of annual chimney inspections contributes to the debate regarding this. “Before every heating season” and “before use” lead many to conclude that annual inspections should be done in fall. “Before further use of the fireplace” might or might not have caused fewer leaps to the same conclusions.

The point really is that the chimney was inspected and then time passed. What was true about it before is no longer necessarily true. No one can know that it is still in good condition. Accordingly, somewhere between last-and-first regular uses – which often are responses to seasonal weather changes – the chimney needs to be inspected.  Which season is the best for that obviously varies with chimneys and circumstance.

There can be good reasons for inspections in any season. The important thing is that home owners not introduce fire to systems of uncertain condition. There are two quick points in that connection which together say, “Home-Buyer Beware!” A home inspector only inspects what he can see and lack of use does not stop time.

All of this becomes especially salient when chimneys have no caps and crowns are improperly constructed. It is extremely difficult, therefore, to pronounce one season better than another for your annual chimney inspection. We can tell you that when problems are detected in spring, there is time to correct them before fall.

We can also tell you that CSIA certified chimney sweeps are conscientious year round, so there is no real problem with fall inspections. That, however, assumes that a certified sweep found everything to be in great condition last fall and there was no change in use. These professionals can work around your choice of season. The important thing is for you to schedule annual inspections.

Water and Your Masonry Chimney

There are two important things to think about in connection with water and masonry chimneys: crowns and caps. The first function to keep water out of the chase and away from the chimney. The second are designed to prevent it from entering the flue, but “full coverage” caps protect the entire crown.

A Wash?

The crown is the highest masonry component of your chimney. Above it are only the flue liner top (typically clay) and its cap (typically metal). It closes the chase around the flue liner and overhangs the rest of the chimney to direct water away from it. Sometimes called a “chimney wash”, it more than pays for its construction and maintenance with its prevention of much more costly damage.

If a crown fails to do its job and the problem is not corrected, the scale tips increasingly toward expensive repairs. Once water gets into the chimney, it freezes and thaws, constantly expanding little cracks into bigger ones. Moisture reacts with creosote and releases smelly gases, and odorless toxic ones have more chance of slipping through cracked liners to remain indoors.

Water begins its slow and steady destruction of your masonry chimney, rusting metals and rotting woods. Neglected long enough, the whole chimney can collapse if its worst enemy is let in on the roof. A crown in good repair and a strong chimney cap are anything but a wash when it comes to safety measures.

King of the Hill, Top of the Heap

Chimney caps are equally important because they do the same thing for the protruding flue liner. The fact that caps are missing from so many chimneys is baffling, although lightweight ones can be taken by wind and animals. Either lots of homeowners are ignoring the good advice of certified chimney sweeps or there are lots of critters on their really windy roofs! That, of course, also calls for chimney caps.

Always Have a Plan of Escape

Was it Colin Powell who pointed out the importance of knowing how you get out before you go in? Whether it’s called an “exit strategy” or an “escape plan”, it is critical to the survival of loved ones regardless of where the fight is. No different than being on a battlefield, facing fire, every family needs to plan and train for their own escape and leave the fight to pros.

Fight Fire with Smoke

Working smoke detectors properly placed can save both your family and your house if you have a good escape plan. It is a tiny fraction of children who cannot be awakened from deep sleep by traditional smoke alarms. Nonetheless, if your child is among them, you need to know, so check it out a few times.

Indeed, the more realistic the practice for an actual escape, the more likely it is to kick in when needed. The presence of that shrill beeping from smoke detectors needs to be familiar rather than something that causes panic. Children who do not wake to them need to be assigned to adults who reliably are, and the plan may have to be re-designed.

Time Is Of the Essence

When the alarms sound, getting the whole family out of the house within 5 minutes at most is the goal. Smoke detectors are extremely sensitive, so they are an essential early warning system.  With a good escape plan that has been well practiced, all family members can get safely out and take the pets with them.

It is important to think about family pets, because all too often they are the reason for someone going back into a burning house. This should never be done; get out and stay out, and let firefighters handle the rest. Plan in advance for all of your loved ones to safely escape from the house, and make the 9-1-1 call a part of the plan.

The Recent Time Change and Your Smoke Detectors

The recent time change for Daylight Savings was more than a reminder to set your clocks forward 1 hour. It was also a reminder that smoke detector batteries should be periodically changed. Advised to use our twice-yearly time changes to keep up with battery strength, homeowners tracking spring’s special occasions and tax return deadlines sometimes forget. Since it really is a good idea for home safety, we thought it worth bringing forward for new attention now that April Fool’s is past.

Why Bother Now?

Smoke and carbon monoxide detectors save lives, but not if their batteries are not good. In addition,  knowing their condition is not easy. If there is any uncertainty about a battery’s remaining life, it should not be in a smoke or gas detector. Remove it and put it in something less essential to safety, like an extra flashlight or a backup alarm clock.

Getting the last possible drop of juice out of every battery is not a great idea when the batteries are in life-saving alarms. All the statistics point to the costly dangers of undetected smoke and toxic gases, with high public awareness now of carbon monoxide in particular. Yet, those inexpensive batteries tend to be things about which we entrust too much confidence in both big-name and unknown brands.

Extend Lives Another Way

How many homeowners really check how many hours their batteries last or at what point their strength has diminished to unacceptable? More and more homeowners with a taste for short-term savings have switched to ‘house wine’ batteries, coming from who knows where. It is incredibly sad but true that spending a few more cents on each battery might save lives.

So, replace them sooner rather than later, and they can still be used in dozens of other common household items where if a battery dies it is literally not a matter of life and death. Children’s toys, gaming devices, phone bases, bike lights; there are any number of things that you can put used batteries into. Performing too important a function, your carbon monoxide and smoke detectors are not the place for them, so it really is time to change them.
