Brick Repointing
This masonry restoration project in Framingham, MA focused on selective brick repointing — targeting the first floor where deterioration was most severe and repointing all window sills due to their high water exposure. Damaged mortar joints were cut to proper depth, new mortar was set and struck correctly, and the yard was fully cleaned after two days of work.
The Challenge
The biggest issue on this project was widespread mortar deterioration, with the most urgent damage concentrated on the first floor and around every window sill.
Window sills are among the most vulnerable sections of any brick exterior. They are fully exposed to rain, standing water, and freeze-thaw cycles — and when mortar joints in those areas begin to fail, moisture can penetrate the masonry and trigger more serious deterioration behind the surface.
The other challenge was making sure the repointing was done correctly rather than cosmetically. A common shortcut in this type of work is to apply new mortar directly over the surface where old mortar is missing, without cutting out the damaged material first. That approach does not create a durable repair. New mortar needs proper joint depth and clean substrate to bond correctly to the existing masonry — without that preparation, fresh repointing can begin failing within months.
We have seen many jobs where surface-patched repointing was already cracking and separating in less than a season. This project required the right method from the start.

Scope of Work
- Setup of scaffolding for safe, stable access to first floor and window sill areas
- Cutting out deteriorated mortar joints to proper depth throughout all repair zones
- Selective repointing of all first floor brick areas with significant mortar deterioration
- Repointing of all window sill masonry joints across the full exterior
- Placing new mortar into properly prepared joints
- Striking and finishing the mortar joints to the correct profile for a clean, durable result
- Full cleanup of the work area, including removal of mortar dust and debris from the surrounding yard
Materials Used
- Masonry mortar — matched to the composition and texture appropriate for this brick exterior
- Angle grinder and chisel tooling — used to cut existing joints to proper depth before new mortar was set
- Jointing tools — used to strike and finish the new mortar joints to a consistent, weather-resistant profile
- Scaffolding — set up for safe access to the repair areas and stable working conditions throughout the project
Challenges Solved
- Identified the first floor and all window sills as the highest-priority repair zones, focusing the work where deterioration was most advanced
- Cut all damaged mortar joints to proper depth before applying new mortar — preventing the shallow surface-patch failure seen on many improperly done repointing jobs
- Repointed all window sill masonry joints specifically because of their high water exposure and role in protecting the underlying structure
- Completed scaffolding setup, joint cutting, mortar installation, striking, and full yard cleanup within a two-day project window
- Delivered a mortar restoration built for long-term performance — not a cosmetic patch — positioning the masonry for decades of reduced maintenance
The Results
The completed project restored the most deteriorated brick and mortar areas of the home while concentrating the repair where it was needed most.
By repointing the first floor masonry and all of the high-exposure window sill areas using proper joint depth and preparation — not surface patching — this project stopped active moisture intrusion at its most vulnerable points and significantly reduced the risk of further masonry damage.
The mortar joints were struck and finished cleanly, the yard was fully cleared of dust and debris, and the exterior was left in a condition that is built to perform for decades rather than months.

Frequently Asked Questions
Why is it important to cut out the old mortar rather than patch over it?
New mortar needs proper depth and a clean joint surface to bond correctly to the existing masonry. If new mortar is applied over the surface of missing or damaged joints without cutting out the old material first, there is not enough thickness or adhesion for the repair to hold. Surface-patched repointing often fails within a single season.
Why were the window sills prioritized for repointing?
Window sills are directly exposed to rain and standing water and experience concentrated moisture load compared to the rest of the wall. When mortar joints in those areas begin to fail, water can penetrate behind the brick and cause deterioration to the underlying structure. Repointing all window sills was one of the most important protective steps on this project.
Why does brick repointing create so much cleanup work?
Cutting out deteriorated mortar joints with an angle grinder or chisel creates a significant amount of fine dust and mortar debris that settles into the surrounding yard, landscaping, and walkways. Thorough cleanup is an essential part of delivering a professional result — and was treated as a formal phase of this project, not an afterthought.
How long does a properly done repointing job last?
When mortar joints are cut to proper depth and new mortar is correctly placed and finished, a quality repointing job can protect a brick exterior for several decades. The exact lifespan depends on mortar mix, exposure conditions, and ongoing maintenance, but it is a far more durable result than any surface patch.
