Chimney Waterproof & Sealing

Protecting your masonry chimney is your first line of defense against expensive rebuilds and repairs.

According to the BRICK INDUSTRY ASSOCIATION, chimneys require special attention and maintenance to prevent costly damage caused by water penetration. Because chimneys project above the roof line, they are vulnerable to the elements. Nearly every chimney you encounter has signs of water damage! When this moisture mixes with the residue in a flue it often turns caustic. Add to this the potential for freeze-thaw damage that we have in the northern Chicago area and you may end up with massive repair costs. This can be avoided by keeping moisture out of the chimney, determining the cause of corrosion, and addressing it with the best corrective measures.

Chimney Saver is 100% vapor permeable, which means it won’t trap water vapors that usually wick through the bricks to the exterior. In other words, it allows the chimney to breathe. Waterproofing and sealing products found in most hardware or home improvement stores fill in the pores of the masonry, trapping the moisture which accelerates the damage particularly in freeze/thaw climates like ours in the Chicagoland area.

Chimney waterproofing is a great way to protect the investment you have made in your home. Make sure to schedule your chimney waterproofing services before the winter.

Sealing with CrownCoat

Small cracks in the chimney crown can be a big problem. Moisture enters these cracks and when mixed with the residue in the chimney this moisture often turns acidic in nature. This can cause the breakdown of the inside of the flue, the mortar joints and can also lead to deterioration of the exterior chimney structure. Another problem that moisture causes with cracked chimney crowns is freeze/thaw damage. We often see examples of freeze/thaw damage with pot holes and road damage. Our area is prone to these types of problems – just think about how they are always working on the roads in the Chicagoland area. The good news is that you can stop this deterioration in its tracks. Sealing the chimney crown is a sure way to prevent this type of moisture damage.

Lindemann Chimney Service is proud to provide protective maintenance services to Northern Chicago and our surrounding communities.
