Philadelphia's freeze-thaw cycles wreak havoc on mortar joints. We remove compromised mortar to a depth of 1 inch using specialized tools that preserve surrounding bricks. Our custom lime-based mortar mix matches historic compositions while meeting modern durability standards.
For rowhouses, we stagger work to maintain structural stability during the process. In Northern Liberties' industrial conversions, we blend new mortar to complement original textures. Every project includes a moisture barrier treatment to slow future deterioration.

Frequently Asked Questions
How often should Philly rowhouses be repointed?
Every 30-50 years depending on exposure. Southwest-facing walls degrade fastest.
Do you work with historic preservation boards?
Yes, we've completed 60+ projects requiring approval from the Philadelphia Historical Commission.
Can you match my 19th century mortar color?
Our lab analysis identifies original aggregate composition for authentic reproductions.
