Chimney Height Violations: The 3’:2’:10’ Rule
For Safety purposes, building code requires that a chimney must meet the 3:2:10 requirement. The 3:2:10 requiremnt states that the chimney must terminate at least 3 feet above the highest point of the roof that it penetrates, and be at least 2 feet higher than anything within an imaginary 10’ horizontal radius encompassing the top of the chimney.
This requirement is primarily for two reasons:
1. To ensure nearby combustible objects are less likely to catch fire. Objects such as trees, roofs gables, walls, etc. must all be kept at a respectable distance to prevent an unintentional fire.
2. To keep your fireplace from smoking into your home by trying to ensure the chimney will draft properly. If the top of your chimney is too close to an adjacent object such as a tree, wall, or nearby building, wind may create a high pressure plane that may push air down your chimney and force smoke into your home. In some situations, even though your chimney meets minimum height requirements, it may still need to be extended higher in order to draft properly.
If your chimney is not tall enough to meet minimum building code, A to Z is very experienced at extending chimneys to their proper heights. When it comes to your chimney’s safety and performance, A to Z goes to great “lengths” in ensuring your safety and comfort aren’t “short” changed!

Several years ago I had one of the biggest chimney sweep companies in town come out to clean my chimney and it was a DISASTER! By the time they finished, my carpets and furniture were covered in dirty, grimy soot, and it was a nightmare to have cleaned!
Because of my past experience with that other company, I was understandably cautious about having another chimney sweep into my home, but I decided to give A to Z since they came highly referred. Needless to say, I was not disappointed! A to Z was on time and very careful to cover my white carpets with fresh, clean tarps not only in front of my fireplace, but everywhere they walked, too!
I could tell they cared deeply about taking care of my home and making sure my experience was a good one! If you are wondering if there's any difference between the quality of service with A to Z versus the competition, believe me, there really is!
