Old brick deserves old methods
Northern Virginia has brickwork going back centuries — farmhouses, churches, old town buildings, and early suburban homes whose brick was laid by hand, one trowel at a time. That masonry was built with different materials than modern work: softer brick, lime mortar, techniques passed down through apprenticeships. Restoring it with modern methods does not preserve it — it destroys it slowly.
Masonry restoration is the discipline of repairing old brickwork the way it was built. Lime mortar for lime-mortar walls. Matching brick, not whatever is cheapest at the yard. Gentle cleaning, not sandblasting. Patience instead of shortcuts. It is slower and more careful than standard masonry repair, and for historic structures it is the only right approach.
Why old masonry fails differently
Historic brick is softer and more porous than modern brick — it was fired at lower temperatures from local clays. It was laid in lime mortar, which is softer than the brick and flexes with the building. This system works beautifully for centuries as long as the mortar stays softer than the brick. The wall breathes, moves, and sheds water the way it was designed to.
The number one destroyer of historic masonry is well-meaning modern repair. Someone repoints with hard Portland cement mortar. Now the mortar is harder than the brick. The wall still moves and freezes, but the mortar will not give — so the brick faces pop off instead. Within a decade, the "restored" wall is worse than the worn original. We see this tragedy constantly, and undoing it is painstaking: the hard mortar has to be carefully removed without damaging the soft brick underneath.
Other killers: sandblasting or pressure-washing, which strips the hard-fired face off old brick and leaves it vulnerable; waterproof sealers that trap moisture inside the wall; and cement stucco smeared over brick, which holds water against the masonry it was supposed to protect.
What restoration involves
It starts with investigation. We identify the brick type, test the original mortar to determine its composition, and document the wall's condition — what is original, what was repaired before (and how), and what is failing now. On significant structures, we recommend a conditions assessment before any work begins, so the restoration plan is based on evidence, not assumptions.
Lime mortar repointing is the core work: raking out failed mortar — including wrong modern mortar from past repairs — and repointing with lime mortar matched to the original in composition, color, and texture. Lime mortar is more forgiving to work with and more forgiving to the building. It cures slower, breathes with the wall, and sacrifices itself to protect the brick, exactly as designed.
Brick replacement uses matched units — salvaged brick from the same era when available, or new handmade brick made to match. We never use modern hard brick in a historic wall; the mismatch in hardness and porosity creates the same problems as wrong mortar. Dutchman repairs (piecing in matching brick sections) preserve as much original fabric as possible.
Gentle cleaning removes decades of grime, paint, or biological growth without damaging the brick. We use the mildest effective method — usually low-pressure water with appropriate detergents, sometimes poultices for stubborn stains. Never sandblasting, never harsh acids on old brick.
What we will not do to your historic masonry
We will not smear Portland cement on your lime-mortar wall. We will not sandblast your brick. We will not seal moisture inside with impermeable coatings. We will not replace your handmade brick with modern extruded units. If a contractor proposes any of these for your historic structure, get a second opinion — preferably from us.
Beyond houses: churches, outbuildings, and landmarks
We restore masonry on more than homes: historic churches, old school buildings, farm outbuildings, cemetery walls, and garden walls. Each has its own character and its own needs, but the principles are the same — compatible materials, gentle methods, and respect for the original craft. If your organization stewards a historic masonry structure, we will assess it and give you a phased plan that respects both the building and the budget.
Our process
Step one: we visit and document — photographing conditions, testing mortar, and understanding the building's history as it relates to the masonry. Step two: you get a free written estimate with our findings in plain language and a restoration plan: what gets done, in what order, with what materials. Step three: we execute carefully — lime mortar work is scheduled for the right weather, and we protect the site throughout. Step four: we review the finished work with you and provide maintenance guidance for the years ahead.
