Why Gutter Maintenance is Key to Masonry Preservation

Peter Merlo

If you're managing a commercial property in Chicago, chances are you've dealt with the consequences of water infiltration at some point. Whether it's freeze-thaw damage, efflorescence, or unexpected deterioration in masonry façades or parapet walls, water is often the common denominator.


And one of the simplest, most overlooked sources? Gutters.


Poor gutter maintenance doesn’t just mean puddles or unsightly streaks on your building. It can quietly speed up the deterioration of your masonry. In our work as commercial masonry restoration contractors, we often trace major issues back to something as preventable like clogged or failing gutters.


Let’s walk through why proactive gutter maintenance should be a core part of your building preservation strategy (and what can happen if it’s not).



How Gutters Protect Masonry (When They’re Working)


Gutters and downspouts are your first line of defense in managing water runoff. When functioning correctly, they redirect water away from:


  • Masonry walls
  • Lintels
  • Foundation areas
  • Expansion joints
  • Balcony slabs


This is especially important in buildings with load-bearing masonry or older façades that don’t have modern cavity wall systems or fail-safes. The Chicago area’s frequent freeze-thaw cycles (an average of 6.5 freeze-thaw events annually) make this even more urgent.

What Happens When Gutters Fail?


When gutters overflow, leak, or detach, they create concentrated water flow that can cause issues over time. Here’s what we typically see in buildings without regular gutter maintenance:


1. Localized Deterioration of Brick and Mortar

Masonry is porous. When water runs down façades repeatedly, it seeps into the brick and mortar. As that water freezes, it expands and leads to spalling, cracks, and joint failure.


2. Damage to Lintels and Shelf Angles

Steel components like lintels and shelf angles are vulnerable to corrosion if water consistently reaches them. Over time, this rust can cause displacement of the masonry above and require full masonry lintel replacement.


3. Cracking and Bulging in Parapet Walls

Overflowing gutters often lead to saturated parapets. That’s why we frequently get called in for concrete facade restoration or brick parapet rebuilds following water damage that began at the roofline.


4. Quicker Need for Tuckpointing

Once water gets into mortar joints, they deteriorate faster. This leads to premature failure and the need for commercial tuckpointing.

Signs Your Gutters May Be Weakening Your Masonry


  • Efflorescence or staining on brick below gutters
  • Cracks that trace down from rooflines or corners
  • Water leaking inside the building along perimeter walls
  • Vegetation growing from joints or parapet tops
  • Ice damming or icicles forming at the roofline


If you’re seeing any of these, it’s worth investigating both the condition of your gutters and the masonry they’re impacting.



Prevention: A Low-Cost Investment That Protects a High-Cost Asset


The cost of a full gutter system cleaning and inspection is usually less than 1% of a complete concrete facade repair, making it a highly efficient preventative measure against long-term deterioration. In fact, one recent study from the National Institute of Building Sciences (via Architect) found that every $1 spent on preventative maintenance saves $4 in future repairs.


We recommend property managers and facilities teams include gutter checks in their quarterly or seasonal inspections, especially before and after winter.

Spring water damage often gets blamed on cracks, failed mortar joints, or deteriorated sealants. In many cases, the real issue starts earlier, at expansion joints that were never designed, detailed, or maintained to manage seasonal movement.  For commercial and multi-family buildings in Chicago, expansion joints are a primary defense against moisture intrusion during spring thaw. When they fail, water finds its way behind masonry, into wall assemblies, and down to steel and concrete elements that were never meant to stay wet.
