Washington, D.C. Historic Property Preservation
Careful Restoration of Washington, D.C.’s Historic Stone Landmarks and Row-House Districts
Historic Building Restoration Specialists in Washington, D.C.
Few cities hold as many protected buildings as Washington, D.C. The brick Pension Building, now the National Building Museum, was finished in 1887. The granite Old Post Office tower followed in 1899, the Willard Hotel in 1901 and Union Station, faced in white granite, in 1907. Georgetown and Capitol Hill are lined with blocks of 19th-century brick row houses and storefronts. Limestone, marble, granite and old brick all take hot, humid summers, thunderstorms and winter freeze-thaw cycles.
Older buildings need repairs that respect how they were built. Mortar must stay softer than historic brick and stone, stone repairs need compatible materials, and harsh cleaning can damage fragile surfaces. Presto Restoration bases every historic scope on the National Park Service’s Preservation Briefs and works with your architect when a project needs review by the D.C. Historic Preservation Review Board, and, for buildings facing federal property, the Commission of Fine Arts.
With more than 25 years of experience, our crews repoint brick and stone with matched lime mortars, repair limestone, marble and granite, restore historic windows, storefronts and decorative metal and apply breathable treatments that protect older walls without trapping moisture that would freeze.
OUR HISTORIC PRESERVATION SERVICES IN WASHINGTON, D.C.
From the stone landmarks downtown to the row houses of Georgetown and Capitol Hill, Presto preserves D.C.’s historic buildings with materials matched to how they were built.
D.C.’s historic brick was laid in soft lime mortar, and generations of freeze-thaw cycles have pushed many joints out. Hard cement repairs are stiffer than the brick and make it crack. We remove failing joints by hand and repoint with lime mortar matched in strength, color and profile.
Limestone and marble weather slowly in rain and city air, and freeze cycles crack them at joints and around rusting anchors. Granite holds up better but its joints still fail. We clean gently, consolidate and patch weathered stone with compatible repair mortars, replace badly damaged pieces and re-anchor loose units with stainless steel.
Original wood windows and cast iron storefronts help define Georgetown, Capitol Hill and the older downtown blocks. We repair and consolidate damaged wood, re-glaze, refinish and seal perimeters so original windows and storefronts stay in service.
Cornices, towers and carved ornament take the worst of the storms and freezes. We secure loose pieces, repair damaged ones and recreate missing details from the originals.
Cast iron, bronze and decorative railings corrode with humidity and winter road salt. We clean and restore historic metals, stop corrosion, apply protective finishes and reseal where metal meets masonry.
Historic stone and brick must be able to dry out, and in a city with real freezes that matters. Sealing the face of an old wall can trap water that freezes and spalls the surface, so we fix the real leak sources first and use breathable treatments only where they help.

Washington, D.C. Historic Preservation FAQs
What makes historic preservation different from regular restoration?
Restoration makes a building sound and watertight. Preservation does that while keeping as much original material and detail as possible, through careful repair, matched materials and gentle cleaning.
Why is limestone and marble on older D.C. buildings wearing away?
Rain and city air slowly dissolve the surface of limestone and marble, and freezing water cracks them at joints. Gentle cleaning, compatible repairs and breathable treatments slow the damage.
Who reviews exterior work on historic buildings in D.C.?
Most work on landmarks and in historic districts goes through the D.C. Historic Preservation Review Board and its staff. Buildings that face federal property may also need review by the Commission of Fine Arts.
How long does a historic restoration project take?
A row house may take a few weeks, while a large hotel or civic landmark can take many months, depending on scope, review and the season.
Can historic storefronts be repaired instead of replaced?
Usually, yes. Cast iron, wood frames and original glass can often be repaired, reglazed and refinished, keeping the building’s character intact.
How do you work with architects and preservation reviewers?
We share survey findings, test results and proposed methods early and document the work with photos throughout.
Does Presto follow National Park Service guidelines?
Yes. Our repointing, stone repair, masonry cleaning and window work follow the National Park Service Preservation Briefs.
