Most leaks don’t start inside… they start right here.
Freeze/thaw in New England destroys deck coatings fast — once water gets in, it spreads into the structure.
We install seamless rubber membrane deck systems that actually stop it at the source.
Boston area buildings, condos, rooftops — this is one of the most overlooked failure points.

STOP LEAKING DECKS BEFORE THEY COST YOU THOUSANDS
Freeze/thaw in New England is brutal on balconies & rooftop decks.
What starts as a small leak turns into serious water damage fast.
We install rubber membrane deck coatings that:
✔️ Stop active leaks
✔️ Seal and protect long-term
✔️ Handle Boston weather
If your building has leaks — now is the time to fix it before it spreads.

Historic buildings in Massachusetts require more than cosmetic repairs.
If water is getting in, the structure is already telling you there’s a problem.
At Gilrace Masonry, we focus on:
•Masonry restoration
•Waterproofing
•Building envelope diagnostics
If you’re an engineer, property manager, or owner dealing with leaks or façade issues — we can help identify the source and fix it correctly.
Most contractors would’ve covered this up. We restored it the right way.
Historic restoration underway at Phillips Academy Andover, one of the most well-known academic campuses in Massachusetts.
Our team at Gilrace Masonry is performing:
•Full brick grinding & repointing
•Precision mortar matching to original historic profile
•Sealant replacement at entry points
•Restoration of granite steps and building envelope details
This isn’t just masonry — this is building envelope restoration done to engineering standards, preserving the integrity of a historic structure while stopping water intrusion at the source.
Projects like this require:
✔️ Attention to original materials
✔️ Proper joint prep (not shortcuts)
✔️ Understanding of long-term performance — not just appearance
Proud to be trusted on another high-level restoration project in the Boston / North Shore Massachusetts area.

This building was one heavy rain away from a serious problem.
Failing steel lintels. Open mortar joints. Water getting in behind the brick.
Most people would’ve patched it.
We tore it open and fixed it right—steel, flashing, repointing, full seal.
Now it’s solid and watertight.
If you own property in Boston and want to know what actually fails (and how to fix it), follow me.
#Boston #RealEstate #Construction #Masonry
Solid project in Chinatown—this is what proper masonry restoration looks like when it’s done right. Steel lintels replaced, brick rebuilt, partial repointing + full grinding/pointing, stainless flashing, window caulking, and new drainage all tied together to stop water issues for good. In Boston, it’s never just brick—it’s structure and water management. If your building is showing signs of failure, now’s the time to address it before it turns into a bigger problem.

Most contractors use the WRONG mortar and don’t even know it.
That’s why you see brick faces popping off 2–5 years later.
We match original composition + strength—not just color.
If you own or manage a building, this matters more than you think.
Most people don’t realize this…
Bad repointing can DESTROY a brick building.
Wrong mortar = trapped moisture = brick failure.
We’re restoring this historic Worcester mill the RIGHT way—matching original mortar so it actually lasts.
Real craftsmanship still matters.
Follow to see how it’s done.

Water intrusion at door openings is one of the most common failure points in masonry buildings—especially in Boston.
This unit had ongoing leaks at the slider due to failed waterproofing and no proper drainage system behind the brick façade.
👉 Once we opened it up, the issue was clear:
•No effective door pan system
•Water trapped with no way to exit
•Deteriorated flashing + compromised substrate
Our solution (done right the first time):
•Removed existing slider and surrounding brickwork
•Installed custom stainless steel door pan with end dams
•Integrated through-wall flashing + GCP Perm-A-Barrier system
•Rebuilt the assembly to ensure proper drainage and long-term performance
💧 Key detail:
Those end dams aren’t optional—they’re what stop water from migrating laterally and getting back into the building.
Most contractors patch the surface.
We fix the system behind it.

If you’re dealing with leaks around windows, doors, or brick façades…
there’s always a bigger issue behind it.
Let’s fix it permanently.

Most of these failures start years before they’re visible. Water gets behind the brick, steel deteriorates, and by the time cracking shows — the structure is already compromised.
This is what water infiltration does over time.
Steel lintel completely gone behind the brick.
No flashing. No protection.
By the time you see cracks — the damage is already done.

Most chimney failures don’t happen overnight — they happen slowly, then all at once.
Water gets in.
Freeze/thaw cycles expand it.
Brick starts separating.
By the time it’s visible from the ground… the damage is already serious.
That’s why we don’t patch structures like this — we rebuild them properly to match the original detail and make them last.
If you own or manage older brick buildings in Boston, this is something you should be checking regularly.

Historic Chimney Restoration – Phillips Academy, North Andover, MA
At Phillips Academy, our team carefully removed the top 3 feet of deteriorated chimney structures and rebuilt them to match the original historic detail—brick for brick, course for course.
This wasn’t just a repair—it was a commitment to preserving craftsmanship from another era. The original masons set the standard, and we made sure to honor it. From precise brick matching to historically accurate detailing, every element was rebuilt with the same level of pride and precision.
Shoutout to the old-school masons—your work still sets the bar. We’re just carrying it forward.
Scope of Work:
• Selective chimney demolition (top 3 feet)
• Full rebuild to original historic profile
• Custom brick matching & layout replication
• Restoration of decorative courses & cap detailing
• Integrated flashing & weatherproofing
Built to last. Built the right way.
