Philadelphia, PA Historic Property Preservation
Careful Restoration of Philadelphia’s Historic Brick, Terra Cotta & Cast Iron Landmarks
Historic Building Restoration Specialists in Philadelphia, PA
Few American cities hold as many historic buildings as Philadelphia. Independence Hall dates to the 1750s, Old City and Society Hill are lined with colonial and Federal brick, and Elfreth’s Alley is one of the oldest continuously lived-in streets in the country. City Hall, completed in 1901, is one of the largest masonry buildings ever built, and Center City adds cast iron storefronts, brownstone rowhouses around Rittenhouse Square and terra cotta office towers from the early twentieth century. Thousands of these buildings are listed on the Philadelphia Register of Historic Places, and all of them face freeze-thaw winters, wind-driven rain and decades of wear.
Older buildings need materials and methods that respect how they were built. Mortar must stay softer than historic brick, cleaning must not damage terra cotta or brownstone, and repairs should match the original. Presto Restoration bases every historic scope on the National Park Service’s Preservation Briefs and works with your architect when a project needs approval from the Philadelphia Historical Commission or review by the Pennsylvania Historical and Museum Commission.
With more than 25 years of experience, our crews repoint brick with matched lime mortars, repair and reset terra cotta, restore brownstone, marble and cast iron, refurbish historic windows and apply breathable treatments that keep each building dry without trapping moisture.
OUR HISTORIC PRESERVATION SERVICES IN PHILADELPHIA
From colonial brick and brownstone rowhouses to cast iron storefronts and terra cotta towers, Presto provides preservation services for Philadelphia’s historic buildings using materials suited to their original construction.
On Philadelphia’s historic brick, mortar usually fails first. Freezing water erodes the original lime mortar until the joints open, and later repairs with hard cement mortar often crack the softer brick. We remove failing joints carefully and repoint with lime mortar matched in strength, color and profile.
Glazed terra cotta, brownstone and marble define much of the city’s character. Water reaching the steel anchors behind terra cotta rusts them and cracks the units, brownstone flakes and peels as water freezes inside it, and marble steps and trim wear and stain. We clean gently, repair cracks and spalls with compatible materials, treat corroded anchors and reset or replace loose units, matching color and profile.
Historic wood and steel windows are central to a building’s character and often must be kept on designated buildings. We repair and refinish frames, re-glaze with new compound and seal perimeters so original windows stay in service.
Cornices, carved stone, terra cotta ornament and decorative brick collect water and deteriorate first, and loose pieces are a safety concern over busy sidewalks. We stabilize loose pieces, repair broken elements and recreate missing details that match the original.
Cast iron storefronts in Old City, iron railings, bronze entrances and copper details appear across Philadelphia’s historic districts. Age and weather leave them rusted or buried under paint. We clean and restore historic metals, stop corrosion, apply protective finishes and reseal metal-to-masonry joints.
Historic masonry must breathe. Sealing the face of an old wall can trap moisture that freezes and damages it, so we fix the actual leaks first and use breathable repellents only where they help.

Philadelphia Historic Preservation FAQs
What makes historic preservation different from regular restoration?
Regular restoration makes a building sound and watertight. Preservation also protects original materials and appearance through matched mortars, gentle cleaning and repair rather than replacement.
Why does lime mortar matter on older Philadelphia buildings?
Historic brick was laid in soft lime mortar meant to be weaker than the brick. Hard cement mortar traps water and stresses the brick, which then cracks in freezing weather.
Can an older building be made watertight without losing its character?
Yes. Most leaks come from eroded mortar, failed flashings, cracked copings and worn window seals, all of which can be repaired with compatible materials.
How long does a historic restoration project take?
A rowhouse facade may take a few weeks, while a large terra cotta tower or church can take many months, with most work done between spring and fall.
Does Presto work on historic properties in Philadelphia?
Yes. For buildings that need approval from the Philadelphia Historical Commission or review by the Pennsylvania Historical and Museum Commission, we provide the scope and material information required.
How do you work with architects and preservation reviewers?
We share survey findings, material testing and proposed methods early and document the work with photos throughout.
Does Presto follow National Park Service guidelines?
Yes. The National Park Service Preservation Briefs guide our methods for repointing, masonry cleaning, terra cotta repair and historic windows.
