Why Full Side Repointing Beats Spot Pointing On Aging Brick Walls
We were walking past a building the other day. Most people don’t think twice about it because the brick looks “good enough” to the untrained eye. As a mason, we noticed the mortar joints right away. Several sections were crumbling, and the patchwork of old spot repairs told a story we see often across Greater Boston: a building that’s been chasing problems one section at a time instead of getting ahead of them.
TL;DR: Spot pointing works for isolated damage, but when mortar deterioration spans an entire wall, repointing one full side at a time delivers a more consistent, longer lasting repair.
What Spot Pointing Is Good For
Spot pointing has a real place in masonry maintenance. If a section of mortar has failed due to a specific issue such as a downspout leak, a tree root, or localized water intrusion, targeting that area makes sense. It’s fast, cost effective, and appropriate when the rest of the wall is in solid condition.
The trouble starts when spot pointing gets used as a default fix on walls where the mortar is uniformly old. Our team at JMS Masonry provides historic masonry services to the Greater Boston area, so we’ve seen a thing or two. And spot pointing is one pattern that shows up again and again on older buildings in Boston, Cambridge, Somerville, and beyond. When mortar joints were installed at the same time and have weathered the same decades of freeze thaw cycles, the areas that look fine today are often only a season or two behind the areas that already failed. This is one of the many reasons why you should always ask your masonry contractor questions in advance. The last thing you want is spot pointing that needs to be revisited sooner rather than later.
Why Full Side Repointing Works Better
Consistency Across The Wall
Repointing one full side at a time addresses the wall as a system rather than a collection of individual joints. Mortar mix, joint profile, and workmanship stay consistent from top to bottom, which matters both for appearance and for how the wall performs against water and freeze thaw damage.
Fewer Return Visits
Property managers and homeowners who rely on spot repairs often find themselves calling back every few years for the next section that has started to fail. Full side repointing breaks that cycle. It costs more at the outset, but it generally reduces the total number of projects needed over the life of the building, which tends to be a better long-term value.
Better Protection For The Substrate
Deteriorated mortar allows water to penetrate behind the brick face, which can affect the structure over time. Addressing a full elevation at once closes those gaps before moisture has a chance to spread further into the wall assembly.
What A Full Side Repointing Project Involves
A full side repointing project generally starts with a survey of the existing mortar to confirm compatibility of the new mix, particularly on historic buildings where original mortar was often lime based rather than modern portland cement. The National Park Service's Preservation Brief on repointing mortar joints is a helpful resource for understanding why matching the original mortar composition matters on older masonry.
From there, the work typically includes:
Removing deteriorated mortar to a consistent depth, repointing with a matched mix and joint profile, and allowing proper cure time before the wall is exposed to weather again. JMS Masonry & Restoration provides repointing services to Boston, Brookline, Newton, and the surrounding communities, and we always recommend a full assessment before deciding between a spot repair and a full elevation.
Talk To A Leading Boston Masonry Contractor Before The Next Section Fails
If a building has mortar joints in similar condition across a wall, it is worth having a mason take a closer look before committing to another round of patch repairs. Our team offers foundation repair and waterproofing services alongside repointing, since these issues often overlap on older structures.
