Chimney Preservation

There are approximately 40 million masonry chimneys in North America and the most common problem with these structures is water penetration. Water causes over 1 billion dollars in damage annually because of deteriorating masonry. Today the modern problem of acid rain accelerates deterioration in your chimneys. All new and existing masonry chimneys are susceptible to water damage and even if repaired, chimneys will continue to deteriorate if they are not protected.

Chimney Water Repellant

10 Year Warranty

Specifically developed to protect chimneys from severe weather conditions.

A water repellent, not a water sealer. Water sealers can actually damage masonry because they trap moisture, rather than allow the chimney to breathe.

Mortar & Joint Repair

10 Year Warranty

Repairs cracks up to 1/8″ in bricks and mortar. It’s nearly invisible when cured.

Crown Preservation

The chimney crown, the top part of your chimney, is the most important part of your chimney and it takes the most abuse. Damage to chimney crowns is the leading cause of deterioration in masonry chimneys. On average, chimney crowns need replacing every 7 to 10 years. Damage comes from the constant contraction and expansion of clay flue liners combined with the relentless abuse of changing weather. If left unattended, even minor cracking will allow water to penetrate the chimney structure and eventually cause masonry problems and costly repairs.

Top Sealing Dampers

How to stop furnace heat from leaking out of our fireplace chimneys? Our Top Sealing dampers.

Why use a a damper?

Old, warped and leaky throat dampers cost homeowners hundreds of dollars a year. With the cost of fuel on the rise, that figure isn’t coming down. Dampers close off the flue properly so that expensive furnace heat does not leak out.

Damper Benefits

Quality stainless steel or aluminum serves as a cap when it is closed. saves heat from escaping out your roof’s “big hole” allows better flow for flue gases exiting the chimney lifetime warranties.

About Chimney Caps

Chimney caps are probably the most inexpensive preventive measure to prevent water leaks, damage to the chimney and birds/critters from nesting inside the chimney. Animal/birds nesting material is usually placed in the chimney during late-Spring/early-Summer by these critters and goes undetected until the furnace begins to heat the house in the cool days of early-Fall. This type of chimney clog is extremely dangerous since carbon monoxide could cause serious consequences to the homeowner.

Chimney caps are probably the most inexpensive preventive measure to prevent water penetration and damage to the chimney.

Chimney caps are probably the most inexpensive preventive measure to prevent water penetration and damage to the chimney. An uncapped chimney can collect rain water and funnel it directly to the chimney interior. Moisture in a chimney flue can contribute to liner deterioration, interfere with draft and create potential for blockages. Caps also will keep birds and animals out of the chimney and can prevent sparks from landing on the roof or other combustible materials if there is a chimney fire. Caps should last a long time if they are made of sturdy, durable and corrosion-resistant material. A full-size chimney cap may be a bit more expensive, but it will cover the entire chimney crown and protect it from wear.

Three reasons every chimney needs a cap:

Rain protection – water causes the greatest damage to your chimney of any of the elements. It soaks into the porous bricks, eats away at the mortar, hastens the destruction of the chimney liner, and destroys the chimney crown. A chimney cap does a great job of protecting your chimney from water damage. For maximum chimney protection Mark Jameson Chimney Contractors recommend a multi-flue cap. That’s because a multi-flue cap covers the entire chimney, not just one flue.

Animal protection – one of the great sources of danger to homeowners is the threat of disease from animals like raccoons, squirrels, birds, and rodents that make their home in their chimneys. A well-made chimney cap will keep those animals out of your home forever. Sturdy mesh and a strong lid keep even the most determined critters at bay.

Spark protection – the mesh screen on our caps protects your home from sparks emitted from your chimney. That means less danger of a fire caused by stray sparks from your fireplace or woodstove.

After The Fire-America’s Best uses only the best chimney water proofing material on the market. This material is called “Chimney Saver” and is manufactured by Saver Systems. This material provides up to 10 times the water protection of typical brands in preventing water leaks and extensive future chimney repairs.

Severe spalling and deterioration is caused by water penetration. Waterproofing is an important step in extending the life of your chimney. Water penetration and freeze/thaw damage results in loss of insulation value and lead to structural failure. Chimney Doctor’s “Chimney Saver” is a penetrating water repellent which protects masonry from destructive water penetration and freezing – thawing damage Listed below is information about our Chimney Saver waterproofing.

Chimney Saver is a water repellent specifically designed to protect masonry from severe weather which assists in preventing expensive reconstruction. It offers long term protection, penetrating into most pores 1/4″, forming a string bond with masonry and concrete. Chimney Saver provided 10 TIMES the water protection of typical brands. It’s important to note that Chimney Saver is not a sealer. Sealers coat surfaces and clog masonry pores, cause surfaces to darken or appear glossy, and trap water vapors which actually accelerate deterioration. Chimney Saver is 100% breathable, releasing water vapor and reducing water absorption. .

Top-Sealing Dampers

The three reasons Mark Jameson Chimney Contractors use Lemance, lock top and Chimolator top sealing dampers is to save energy dollars, protect from water leaks and to prevent birds/critters from entering the chimney.

Three reasons to use Lyemance™ or Lock-Top™ top-sealing damper

Save energy dollars – traditional throat dampers have a metal-to-metal seal. Even when they are new they leak. That leaking gets worse over time as they rust and warp with heat. That means even when they are closed they allow warm air from your home to escape up the chimney. This adds significantly to your energy costs. Lyemance and Lock-Top top-sealing dampers seal with a silicone rubber gasket that seals warm air in 90% more effectively than even new throat dampers.

Protect your chimney from water damage – damage caused by water from rain and snow will destroy your chimney. Water runs down your chimney and erodes the mortar joints and damages the firebox in your fireplace. Our top-sealing dampers will protect your inner chimney from water damage during those times you are not using your fireplace.

Top-sealing dampers can also prevent animals from entering your chimney. Raccoons, squirrels, birds, and rodents love to move into chimneys. Our top-sealing dampers will help keep them out.

A work on quality. There’s a reason Lyemance and Lock-Top dampers are installed on more chimneys every year than any other brand. They both carry a lifetime warranty. They’re made of solid cast aluminum and stainless steel parts assembled to exact standards. If you want the best top-sealed damper money can buy, choose Lyemance or Lock-Top. Everything else is a distant second.

Lock-Top™ seals heat in like a Thermos™ lid

When you shut a damper you want to keep the warm air in your home from escaping up the flue. The throat damper in most masonry chimneys does a poor job of this with its metal-to-metal seal. Lock-Top dampers seal tight with a silicone rubber gasket that is 90% more effective than a new throat damper.
