Chimney Rebuilding vs. Re-Pointing: What’s the Difference?

Whether your chimney is crumbling from moisture damage or old age, it’s a significant problem that must be addressed. Two solutions to a damaged and crumbling chimney are repointing and rebuilding. Chimney masonry services can bring your chimney back into tip-top shape and save you from major headaches down the road. So, what’s the difference between chimney rebuilding and chimney repointing?

Chimney Repointing

The chimney is constructed with motor joints to keep the structure in place. As years go by, the mortar joints can begin to decay and create voids in areas of your chimney such as in between the bricks. This is typically the result of exposure to the elements, including the freeze and thaw cycle during brutal Boston winters.

If your chimney’s brick are in good shape, repointing might be the best option for you. This option helps repair the appearance, as well as, the structure of your chimney. It also prevents further damage and moisture from entering between the bricks. This is what can ultimately lead to your chimney experiencing major structural damage to the point where it needs rebuilding.chimney rebuilding

The process of repointing involves grinding out the mortar joints between the brick within by ¼” to ½”. The joints are then filled back in with new mortar and the excess is removed for a smooth and beautiful new look for your chimney!

Chimney Rebuilding

There are some circumstances where a chimney’s repair goes beyond repointing. Rebuilding a chimney is often the result of years of neglect. The chimney can be unsafe to use until it is rebuilt.

There are several types of chimney rebuilding:

  • Partial chimney rebuild: This is performed on smaller sections on a larger chimney or a small chimney. It sometimes includes a chimney crown rebuild.
  • Roofline up rebuild: This is when a new chimney is built up from the roof flashing. A roof line up rebuild is the best option when pointing won’t sufficiently repair the damage.
  • Complete rebuild: A complete rebuild is needed when the entire chimney structure is damaged. Example scenarios that require a complete rebuild includes spawning, leaning, and severe mortar deterioration.
