Have you waterproofed yet?

Flash Seal in NHYour chimney is the pinnacle of your home. It provides you with a focal point from the outside and practicality on the inside. Your chimney allows for you to build wonderful fires to create a beautiful atmosphere for your home. In New England, fireplaces get the most use in the winter when the bitter cold attaches to our bones and follows us inside. Warming up by the fire is an amazing feeling and cannot be compared to anything else. But, is your chimney water proofed and fully protected?

You may wonder what waterproofing a chimney has to do with any chimney maintenance. It is outside against the elements and there is no way it is being damaged that much by water on the inside. It was made to be outside! That is where you are wrong. Your chimney can slowly erode away and create an unsightly and dangerous chimney the longer it is exposed to the elements without some type of protection. Inside and out your chimney is exposed to elements and water vapor. Properly sealing your chimney is the only way to protect it properly so it can last you much longer.

What does water around my chimney do?

According to the Chimney Sweep Institute of America, water damage around your chimney can lead to a vast array of damage. Straight from their “Water and your Masonry Chimney” page, the CSIA state that the following can occur:

  • Water Stained Walls
  • Collapsed hearth support
  • Cracked of deteriorated flue lining
  • Stained Chimney exterior
  • Rotting Wood
  • Rust

Now, with these risks attached to an exposed chimney it is very important to consider water proofing. It will add a sense of protection to the rest of your home and make your chimney last a little longer than before.

At Crown Chimney we use the Chimney Saver line of water proofing products. The way this product works it by using siloxanes that are small enough to penetrate masonry up to ¼ of an inch or more. Siloxane is a chemical compound that is made up of “silicon and oxygen atoms with the silicon atoms bound to hydrogen or organic groups” according to The Free Dictionary. This compound creates a strong bond with the silica that is found in masonry and concrete which makes it easy to bind to your chimney. With Chimney Saver, the one application is good for up to ten times the water repellent protections of typical sealers. It also allows the chimney to breath which is important for the use of expansion with heat.

Sealant or repellent?

It is important to note that the Chimney Saver product that we use is a Water Repellent, not a sealer. Sealers remain on the surface of the chimney and do not always pass through the barrier to protect the inner of the chimney. Repellents are able to soak into the chimney providing an extra level of protection. Long term protection, along with typical chimney maintenance could save you money in the long run.

When you protect your chimney properly today it could save you from costly chimney repairs in the future. Remember that when you look into regularly scheduled maintenance, like inspections and chimney sweeping, make sure you ask about Chimney Saver Water Repellents to protect your chimney for years to come.

Chimney Caps

chimney liningChances are your chimney, depending on how old it is won’t have a chimney cap. So the question to ask yourself is if it is worth getting a chimney cap added to your chimney. But, what exactly is a chimney cap and will it complicate my chimney maintenance?

Well, the name is fairly self-explanatory. A chimney caps are a cover for your chimney to help protect it. They come in a variety of styles, materials and designs. Though they can cost a pretty penny it is an addition to your chimney that could extend the life of your chimney and keep the cost of chimney repair lower than an unprotected chimney.

A basic chimney cap costs by itself about 50 dollars and up, then the cost of installation. However, the positives outweigh the initial cost. Here are a few things that the chimney cap can protect your chimney from.

Water

The chimney cap will mainly keep rain out of your chimney. This would in turn reduce moisture, which will promote better burning of the wood as well as protect the masonry of your chimney. Exposure to water will eventually deteriorate the material leading to costly repairs.

Animals

A chimney cap will also reduce the occurrence of unwanted visitors. The squirrel is cute when it is outside in your yard munching on acorns, but once they enter your house they become more of a fluffy menace than an adorable fluff ball. Chimney caps will keep animals from getting into your flue leading to sanity for you and safety for the animal as well. If they get stuck, it will not be pleasant so it is best for both ends of the scale. Some chimney caps will come with screens as well to further protect against animals and other things from entering your house, but the screen is optional.

Debris

Hurricanes! Blizzards! Tornadoes? So New England doesn’t get tornadoes often so they aren’t serious threats (remember when Springfield, MA got those tornadoes in 2011?). The point is all of these issues can drop debris such as leaves, twigs and branches inside the flue. These will get caught and mess up the natural draft of the flue that is needed for a good fire. It could also cause smoke to re-enter your home instead of venting like it should.

Chimney Caps, though not required are extremely helpful in chimney maintenance. When it comes time for your inspection and cleaning they are removable and are able to be cleaned themselves so you do not need to worry about creosote building up in your chimney. They are created to ease the worry of your chimney, not make it worse.

If you are considering a Chimney Cap, Crown Chimney can help you decide which one will be right for you. We offer copper, Stainless steel and masonry chimney caps for you to choose from. We will install them and make sure that they are done to code every time.

Superior Waterproofing Technology

Chimney WaterproofingChimney saver contains patented siloxanes small enough to penetrate most masonry pore up to ¼” or more. These special siloxanes form strong bonds with the silica in masonry and concrete. Because of this bonding process, one application of chimney saver provides up to ten times the water repellent protections of typical sealers while maintaining the masonry’s breathability.

Water Damage can be prevented

Chimneys are highly exposed to the elements and, if left unprotected, are susceptible to structural deterioration. It is important to address this problem before serious damage occurs. A complete chimney protection program should repairing the crown with Crown Seal or Crown Coat, as well as water proofing the entire chimney with Chimney saver water repellent.

Chimney Spalling

Severe spalling and deterioration is caused by water penetration.

 

Efflorescence stains

Efflorescence stains caused by water penetration and leaching salts are unsightly and add to deterioration.

Water penetration and freeze/thaw damage result in loss of insulation value and lead to structural failure.

Protect your Investment

There are approximately 40 million masonry chimneys in North America and the most common problem with these structures is water penetration. Water cause over a billion dollars in damage annually in the form of staining, loss of the insulation value, freeze-thaw damage, deterioration, and ultimately structural failure.

Chimney Saver is a WATER REPELLENT – not a water sealer. The difference could save you hundreds, or even thousands of dollars in repairs because sealers can actually damage masonry. Unlike water proofing sealer that remain on the surface, Chimney Saver penetrates deep enough to protect masonry from destructive water penetration while maintaining the structure’s vapor permeability.
