Why are the clothes taking so long to dry?

Your dryer vent is a similar system to your fireplace chimney or furnace flue.  Its purpose is to vent heat and lint from the clothes dryer. It needs regular maintenance to properly function…just like your chimney and furnace.  If it isn’t maintained, the clothes dryer may become a serious fire hazard…just like your chimney or furnace.

Danger, Will Robinson, Danger……

Many installers don’t know how to install or even realize that a dryer vent should be installed to specific safety standards.   Many of the standards are outlined in the User Guide. For example, the total length of the run for the vent should not exceed 25 feet.  And every 90-degree turn counts for 5 feet. The pipe itself must be at least 4”. A lightweight flexible pipe should only be used as a connector and not for the main vent run.  

There are many dryer vent related fires that cause loss of life and property each year.  However, they are preventable with proper installation, use, and maintenance of clothes dryers and their venting systems.  The majority of these fires were caused by simple failure to clean the dryer vent on a regular basis.

The Problems….

Many homeowners incorrectly think that routinely emptying the lint trap is all it takes for a clean dryer vent.  Not so…..

Your clothes dryer may not have been installed correctly.  An inspection by a qualified professional can give you peace of mind as to whether your appliance has been installed properly.  

Please read the complete User Guide from your dryer manufacturer.  Please give special attention to the parts about maintenance and use. There should be specific maintenance instructions for each model.  Get to know your appliance, and follow instructions and schedule regular maintenance to ensure proper operation.

How do you know if you need maintenance?

Have you noticed a change in your dryer’s performance?   It’s likely a dryer vent problem. Things to notice:

  • A normal load of clothes takes more than one cycle to dry completely.
  • The surface of the dryer feels hotter than usual.
  • Clothes are excessively hot at the end of the drying cycle.
  • The temperature in the house rises while the dryer runs.
  • The area around the dryer covers in condensation or lint while the dryer is in use.
  • The outlet outside at the end of your dryer vent doesn’t have any air/lint moving thru it.

Benefits of regular maintenance…

  • Saves money when you use less energy
    • by running fewer cycles
    • by not having to cool a house overheated by a malfunctioning dryer.
  • Lengthens the life of your dryer when you run fewer cycles.

 

Take advantage of the “Spring Cleaning” bug to get your dryer checked out.  It’s a perfect add-on when getting your chimney cleaned at the end of the burning season.  

 

Dealing with Water Damage to Your Chimney

APRIL SHOWERS BRING MAY FLOWERS…..

But before they do, your chimney might just spring a leak.  After all, a chimney is just a big sponge. Like a sponge — when it gets saturated, the water will run out anywhere and anyhow it can. Depending on how many bricks are exposed to the elements and available to soak up water, there is the potential for a great deal of water, to be managed, and with it the possibility of leaking into your home’s structure.  If it is not dealt with, over time, the chimney structure can even become compromised.

If you’d like to know more about water’s effects on masonry chimneys, please feel free to check out CSIA.ORG.

Sometimes it is obvious where the water is coming in. Given enough time, it will make its presence known.  However, more insidious water leaks often go unnoticed until there is damage and can be difficult to diagnose as to the exact entry point. Usually, there is more than one problem. A visual inspection can reveal likely possibilities and probable remedies. Sometimes where the water is being seen can indicate one or more of the four most common sources as being the most likely point of entry. In other cases, it is a trial and error process to pinpoint the source.

Most Common Points of Entry

  • No chimney cap or too small chimney cap
  • Cracked and porous crown wash
  • Absorption through brick due to
    • Old, porous brick and/or mortar
    • Deteriorated mortar joints with voids/holes
  • Deteriorated or badly installed flashing
  • No cricket or saddle on the broad side of a chimney downhill from a peak

There are products and methods to address these problems.

  • A full coverage chimney cap, preferably with a lid (with drip edge) that overhangs the sides of the chimney, can prevent rain from entering the flue and provide added protection for crown wash.**
  • An elastomeric coating can seal the crown wash or a cast and poured crown with a drip edge can be created. Either option helps prevent water from freely soaking in from the top.
  • A breathable water repellant and/or crack sealer designed for chimneys applied to the brick and mortar can prevent water from soaking in from the sides.
  • Deteriorated mortar joints can be tuck-pointed.  Holed can be filled.
  • Complete rebuild may be necessary if an aging chimney is too deteriorated to repair.
  • Metal flashing can be repaired or replaced; or a flexible, surface bonded flashing can be applied to correct improper or deteriorated flashing.
  • A cricket can be added to the roof at the base of a chimney where water tends to puddle during heavy rains.

How do you know if it’s the chimney or the roof?

One way is to wrap the chimney with plastic and wait for rain.   No sign of water even though it rains, says it’s probably the chimney.   If you still see water with the rains when the chimney is wrapped, the leak is probably in the roof uphill from the chimney and water is running down to the chimney.
