It’s been an ongoing debate about whether it’s okay to paint historic brick or whether it should remain unpainted. This argument does not have a clear verdict and there are many arguments for both sides. Preservation experts often differ in their views on the issue. We’ll also state here, (SPOILER ALERT), that as this article examines the different sides of the debate, we have strong opinions but no clear final verdict, because it’s a complicated topic. This story, too, unfortunately, ends in a cliffhanger.

Considering whether to paint historic brick? Discover the key factors, benefits, and potential risks to make an informed decision.

In this week’s blog article we are examining some of the specific causes of masonry deterioration. This past week, we mentioned several of these issues in the case study from the field, looking at an area of subsidence in a masonry paving area. These issues included: material porosity, temperature fluctuations, moisture exposure, structural loading, chemical interactions, and microstructural changes. Today, we will start a series which will continue into the new year looking closer at each of these issues.

In the field to preservation and deterioration, the problem is problem itself is causing the problem. Of course that sentence doesn’t make much sense, by itself, without further context, but we will explain, referencing a particular case and looking at a particular set of photographs from the field.

Explore the critical relationship between subsurface hydration and brick paving. Understand how moisture beneath the surface can lead to paving issues and learn effective strategies for prevention and repair

At the building shown in the picture below, each of the windows has a doric entablature built from wood that protrudes away from the front facade of the building. This is, essentially, a type of decorative window header, similar to a pediment in a more classical architecture. This header provides a decorative element to dress the window and add a decor to the front facade. The entablature though also provides a bit of a shield from typical non-wind-driven rainfall. It, essentially, keeps the window a little bit drier than it would be otherwise during normal rain conditions.

Discover the elegance of a Doric Window Entablature, blending classic architectural elements with modern design. Learn about its significance and how it enhances your structure’s aesthetic.

In the upcoming year, we’re going to write an article about “ghost buildings” which isn’t about ghosts at all actually. It is will be about buildings that are already gone and demolished, yet the shadow of the old buildings is left on remaining historic buildings.

Today, we’re taking a look at a local masonry restoration project where it was important to match the mortar color. This is a little bit different than the typical repointing or tuck pointing job. This is a granite stone with a beaded joint. This building happens to be a historic church here in Washington DC.

Discover the importance of choosing the right mortar color for spot mortar restoration. Learn how matching mortar enhances structural integrity and preserves aesthetic appeal.

Back in the early part of the summer season, we looked at chimneys on different rooftops that were in different stages of deterioration and neglect. Most of these chimneys were possibly still in use or able to be refurbished for use to either exhaust gas or air exhaust from chimneys or mechanical devices from inside of the building. However, those chimneys were in different stages of disrepair and needed to either have masonry restoration such as repointing, chimney crown rebuilding, and or recapping.

Just because a historic brick chimney is old, that doesn’t mean that it can’t be maintained, restored, and maintained in good condition. In fact there are many examples here in Washington DC of historical chimneys that work near perfectly well almost as good as the day that they were first built if they’re just properly maintained with good care and stewardship and maintenance.

Discover the importance of preserving and revitalizing old historic chimneys, exploring methods to restore these architectural legacies for future generations.
