Chimney Crown And Shoulder Resurfacing

Shoulder & Crown Diagram-Sacramento CA-AtoZChimney

Shoulder & Crown Diagram

On most masonry chimneys, there is a “crown” on the very top and a pair of “shoulders” where the chimney flares out. Like your home’s roof, these horizontal surfaces are designed to keep harmful rainwater from penetrating your chimney’s brickwork. Because these horizontal surfaces are fully exposed to all the elements (sun, rain, heat, cold, etc.), they generally begin to crack and develop leaks in short order.

You’ll want to prevent your chimney’s crown and shoulders from leaking at all costs, as water leaks in masonry chimneys cause more damage as a whole than any other element, including chimney fires. These leaks not only compromise the safety, efficiency, and structural integrity of your chimney, but can cause water damage to the ceilings, walls, and floors around your chimney.

If your chimney’s crown and/or shoulders are cracked and weathered, your chimney—and everything it is connected to—is suffering more than you know. Every time it rains, water likely seeps down into the top 3-5 layers of brick, which causes the mortar to prematurely become soft, thus allowing the bricks to become loose. If you put off repairs to your chimney’s crown and shoulders, your chimney’s brickwork will eventually loosen, and you’ll need to have the top several layers of your chimney rebuilt. Such repairs are often $1,000 – $2,000—certainly nothing to sneeze at. Luckily, there’s a great way to protect your crown and its surrounding masonry. Those of us at A to Z Chimney Services swear by a product called CrownSeal.

A new crown is poured once the bricks are extended in order to hold the top flue tile safely in position for years to come.

All About CrownSeal

When it comes to your chimney’s crown and shoulders, an ounce of prevention is better than a pound of cure. Avoid expensive masonry and crown repairs by having your crown and shoulders professionally resurfaced with ChimneySaver’s CrownSeal.

CrownSeal is a fireproof, waterproof, environmentally-friendly, and permanently flexible membrane that’s specially engineered for chimneys. It dries in approximately six hours, cures in 24 hours, and has a natural concrete/mortar appearance. If desired, it can be colored with mortar dye. With a 10-year warranty, CrownSeal will keep the water out of your chimney and keep more of your money in your pocket.

In addition to preventing damage, CrownSeal does a great job of repairing severely cracked chimney crowns. However, sometimes the crown is just too damaged to repair, and it will need to be torn off and rebuilt. Read more about our crown construction here.

Dear A to Z Chimney

I just wanted to thank you from the bottom of my heart for the great service you have done for me. I am an avid wood burner and love to burn my fires just about every evening. There’s nothing like the simple pleasure of curling up next to a warm and cozy fire during those cold winter nights.

Unfortunately, I had a chimney fire which did extensive damage to my chimney and it had to be re-lined with a new Stainless Steel Liner.

Last year, I hired a different company to come out and sweep my chimney. The sweep from that company tried to use high pressure sales tactics to get me to do the repairs. His poor attitude and high pressure turned me off so badly that I decided not to have them do the work.

This year, I hired your company and Chris Donovan was such a gentleman! He gave me the same bad news, but this time I could see it with my own eyes on the screen as he video scanned my flue. He was also much more knowledgeable and informative and really took the time to help me understand. He did not talk condescendingly, and there was no pressure whatsoever.

Consequently, I did hire your company to come back and complete the needed repairs, and was absolutely delighted!! Not only did Chris come back, but Aaron, the owner came, as well. I was delighted to know that the owner was personally seeing to the work. In the process of repairing my chimney, some other minor problems were detected, and they fixed them at no additional charge!

In addition, when everything was done, they did a spectacular job cleaning up every bit of their mess, and I couldn’t even tell they had been here.

Thanks again for the great service you provide! I will use you again and again, and refer you to my friends.
